(R M Ts-1400)
The bed of a rigid structure with inclined ribs for chip removal back has four guides: two identical prismatic guides for the carriage and two for the tailstock, one of them is flat (No. 01 Fig. 7).
The left cabinet has large dimensions; at the back, the main drive motor is attached to it, mounted on a plate with adjustment for belt tension. In the right cabinet there is a tank with an emulsion and an electric cooling pump.
Paws are made for foundation screws.
Gearbox
The gearbox (No. 02) is installed on the left side of the bed. Spindle alignment in the horizontal plane is carried out by turning the box around the pin, pressed into the frame under the front of the box, with the help of set screws located at the bottom of the back of the box. All gears of the kinematic chain of the gearbox are mounted on five splined shafts and a spindle, made of chromium steel, hardened, shaving or ground. The shafts are mounted on rolling bearings. The front spindle bearing with adjustable radial clearance is a special 2-row bearing with short cylindrical rollers and a tapered inner ring.
The rear spindle bearing is a radial-thrust, working in pars with a thrust ball bearing, which absorbs the axial feed forces during direct turning. The front end of the spindle is threaded. The spindle has 22 speeds from 10 to 1250 rpm, the progression denominator is 1.26. The change in the number of revolutions of the spindle is carried out by moving the gear blocks along the splined shafts with the help of two handles brought to the front wall of the gearbox. The spindle is reversed by a friction clutch. Braking - electromagnetic clutch 116 (see the kinematic diagram of Fig. 9).
tailstock
The tailstock of a rigid design is fixed to the bed rails with the help of two bars with three bolts. The transverse displacement of the headstock body relative to the bridge is carried out with the help of screws and a nut installed in the bridge. Pi zeros are moved by hand using a handwheel. The tailstock moves along the frame guides on 4 ball bearings installed in the bridge (No. 03 fig. 7 and 8).
caliper
The support of the cross structure (No. 04) has a longitudinal movement along the frame guides and a transverse movement along the carriage guides; either one or the other movement can be manual, mechanical, working and accelerated. The rotary part of the caliper has guides for moving the upper part of the caliper with the cutter head. The upper part of the caliper can also be moved manually and mechanically. The cross screw nut has a slot for adjusting the backlash. The axial forces of the transverse screw and the screw of the upper slide are perceived by thrust ball bearings. The guides for the longitudinal movement of the caliper have textolite linings.
Apron
Closed type apron with removable front wall (lid) (No. 06). The movement of the support group will be transmitted by the apron from the lead screw or the lead shaft. Due to the presence of 4 electromagnetic clutches in the apron, the control of the apron is concentrated in one handle, and the direction of turning on the handle coincides with the direction of movement of the feed. By additionally pressing the button built into the same handle, include an accelerated stroke of the caliper.Due to the presence of an overrunning clutch in the apron, the inclusion of an accelerated stroke is possible when the feed is turned on.In order to avoid the simultaneous activation of the mother nut and the feed, their activation handles are interlocked.
Gearbox
The feed box is of a closed type. Correction gears installed in the feed cow allow cutting two types of threads, metric and inch, without rearranging change gears (No. 07). When rearranging interchangeable gears, it is possible to cut two more types of threads: modular and pitch. There is also a direct connection to the screw (bypassing the mechanisms of the feed box) for cutting precise and special threads. To obtain an increased feed or right-hand thread, a gear block is provided located in the gearbox. The body of the feed box has 2 longitudinal bores, in which the shafts are mounted on rolling bearings. The gears are made of chromium steel and hardened. The choice of feed rates is carried out by two handles by moving the gear blocks. The choice of the type of thread or the inclusion in the feed is carried out by handles 1 and 24. To turn on the screw directly, handle 1 must be set to the "metric thread" position, handle 2 - to the "screw directly", handle 24 - "lead screw" (see diagram controls Fig. 7, 8).
Interchangeable gears
Sets of interchangeable gears for obtaining metric and inch or modular and pitch threads are attached to the machine and are located on the wall of the gearbox housing (No. 08).
In addition, a set of interchangeable gears is attached to the machine for threading when the lead screw is turned on directly. In addition to the common casing that covers the entire left wall of the gearbox, the change gears are equipped with a separate protective casing.
lunettes
The machine is equipped with two steady rests, movable and fixed, for processing round parts with a diameter of 20 to 150 mm (No. 10).
The lunettes are equipped with replaceable rollers and crackers, which are installed depending on the working conditions.
Before starting the operation of the machine, it is necessary to connect its electrical part to the workshop network using the VP packet switch (Fig. 14). When the package switch is turned to the “on” position, voltage is supplied to the step-down transformers TB-0.4 and TPB-50 for supplying the machine motor control circuits, selenium rectifiers and the local lighting lamp, which is fixed by the light of the LS lamp.
Control of the main drive of the machine
The electric motor is started by pressing one of the "Start" 1KU or 2KU buttons (located on the carriage and near the short feed) with the clutch off, which closes the power circuit of the magnetic coil of the 1K starter (9-10). The coil, under the influence of the current passing through it, attracts the armature core and closes the main contacts and auxiliary contacts mechanically connected to it.The main contacts at the same time connect the main electric motor IM to the network, and the starter coil is powered through the closed auxiliary contact 1K (7-23), which excludes further pressing the "Start" button.
Simultaneously with the starter coil, it receives power from the time relay RV, which serves as an idle speed limiter through N. O. auxiliary contact 1K (31-26). If the clutch N. 3. contact VK (7-8) remains closed, the time relay and the brake clutch are turned on, then with a time delay of 2-3 minutes, the PB relay will disconnect the main electric motor from the network with its contact (10-29). When the friction clutch H. 3. is switched on, the VK contact breaks, turns off the time relay and ensures the operation of the machine.
The electric motor is stopped by pressing one of the "Stop" ZKU or 4KU buttons (located on the carriage and near the feed box), which opens the circuit of the IK starter coil (0-10), as a result of which the armature core falls off and opens all contacts of the 1K starter.
When the machine is stopped by means of a clutch through the limit switch VK (7-8), the time relay coil RV is energized, with its NO contact it turns on the brake clutch, and with a time delay of 2-3 minutes. (unless the clutch is engaged again) will disconnect the main engine from the mains.
The electric pump is controlled using the "Start" 6KU and "Stop - 5KU" buttons.
Working feed and rapid traverse drive control
1. There are four electromagnetic friction clutches in the apron of the machine, two of which are used to move the carriage in the longitudinal direction and two to move the support in the transverse direction. Working feeds are carried out from the main drive, accelerated moves - from the engine of the accelerated course.
To control the drives of working feeds and rapid movements of the caliper, there is a special handle on the apron that has 5 positions: one - vertically neutral and 4 - inclined, corresponding to the direction of movement of the caliper or carriage.
By tilting the handle, the electromagnetic clutch is switched on, which transmits movement to the apron (caliper) in the direction corresponding to its inclination. To turn on the electric motor of the accelerated course, at any position of the clutch shift handle, a starting jog button is built into the head of the handle.
To turn on the working feeds in the desired direction, you only need to tilt the handle in the same direction, and to quickly move in the desired direction, you should also press the jog button.
2. In order to avoid simultaneous switching on of the mother nut and electromagnetic couplings of the apron, a blocking limit switch (VKF) is installed inside the apron, which disables the couplings when the mother nut is turned on.
163 Universal screw-cutting lathe is designed to perform a variety of turning and screw-cutting operations on ferrous and non-ferrous metals, including turning cones, cutting metric, modular, inch and pitch threads. The rigid design of the machine 163, the high speed limit of the spindle (1250 rpm) and the relatively large drive power (13 kW) make it possible to use it as a high-speed machine using cutters made of high-speed steel and hard alloys. The use of the step increase mechanism makes it possible to increase feeds: at spindle speeds up to 80 rpm - by 16 times, at spindle speeds from 100 - 315 rpm - by 4 times.
Specifications and rigidity of the design of the bed, carriage, spindle of the machine allow you to fully use the possibilities of working on high speeds cutting with the use of cutters made of high-speed steel or equipped with hard alloy plates when machining parts made of ferrous and non-ferrous metals.
The caliper of the machine 163 has a mechanical movement of the upper part, which allows turning long cones. Turning short tapers is also carried out by moving the upper part of the caliper.
Changing the feed rate and setting the pitch of the thread to be cut are carried out by switching the gear wheels of the feed box and setting the guitar of interchangeable gears.
The caliper has a fast movement in the longitudinal and transverse directions, which is carried out from an individual electric motor.
The production of the model 163 screw-cutting lathe began in 1956. The developer is the Ryazan Special Bureau of Machine Tool Building. Screw-cutting lathe mod. 163 was produced for a long time at the machine-tool plant named after S. Kirov in Tbilisi. This is typical for that time heavy lathe, which was installed in factory metalworking shops or in large repair shops.

Machine spindle 163 mounted on two bearings:
- Spindle front bearing radial special 2-row with short cylindrical rollers and tapered inner ring, with adjustable radial clearance.
- The rear spindle bearing is an angular contact bearing, working in tandem with a thrust ball bearing that absorbs axial feed forces during direct turning.
The spindle has a through hole Ø70 mm, it receives from the gearbox 22 rotation speeds in the range from 10 to 1250 rpm (progression denominator 1.26) and 11 reverse rotation speeds in the range from 18 to 1800 rpm.
The change in the number of revolutions of the spindle is carried out by moving the gear blocks along the splined shafts with the help of two handles brought to the front wall of the gearbox. The spindle is reversed by a friction clutch. Braking - electromagnetic clutch.
Front end of the spindle threaded. Internal (tool) spindle taper - Morse 6.
Spindle alignment in the horizontal plane is carried out by turning the headstock around the pin, pressed into the frame under the front of the gearbox, using set screws located at the bottom of the rear of the gearbox.
All gears of the kinematic chain of the gearbox are mounted on five splined shafts and the spindle is made of chromium steel, hardened, shaving or ground. The shafts are mounted on rolling bearings.
Machine support 163 cross design has a mechanical movement of the upper part, which allows turning long cones. Turning short tapers is also carried out by moving the upper part of the caliper.
The caliper carriage moves along the frame guides (longitudinal movement), the cross slide of the caliper moves along the carriage guides (transverse movement); both can be manual, mechanical, working and accelerated. The rotary part of the caliper, located on the cross slide, has guides for moving the upper part of the caliper (cutting sled) with a cutter head. The lower part of the support (cutting slide) can also be moved manually and mechanically. The cross screw nut has a slot for backlash elimination adjustment. The axial forces of the transverse screw and the screw of the upper slide are taken up by thrust ball bearings. The guides for the longitudinal movement of the caliper have textolite linings.
The main operations are mechanized in the machine: longitudinal and transverse movement of the caliper, movement of the incisor sled. There are accelerated movements of the caliper in the longitudinal and transverse directions, and the incisor sled, which is carried out from an individual electric motor. The spindle is also braked automatically when the friction clutch is turned off.
Mechanical movement of the upper part of the caliper allows turning long tapers. Turning short tapers is also carried out by moving the upper part of the caliper.
Changing the feed rate and setting the pitch of the thread to be cut are carried out by switching the gear wheels of the feed box and setting the guitar of interchangeable gears.
The caliper has a fast movement in the longitudinal and transverse directions, which is carried out from an individual electric motor.
Apron closed type with a removable front wall (lid). The movement of the caliper group is transmitted by an apron from the lead screw or the lead shaft. Due to the presence of 4 electromagnetic clutches in the apron, the control of the apron is concentrated in one handle, and the direction of turning on the handle coincides with the direction of movement of the feed. With an additional push of a button built into the same handle, the caliper accelerates. Due to: the presence of an overrunning clutch in the apron, the inclusion of rapid travel is possible with the feed turned on. In order to avoid simultaneous turning on of the nut by the queen and the feed of the turning handle, they are interlocked.
Closed feed box. Corrected gears installed in the feed box make it possible to cut two types of threads, metric and inch, without changing gears. When rearranging interchangeable gears, it is possible to cut two more: types of threads, modular and pitch. There is also a direct connection to the screw (bypassing the mechanisms of the feed box) for cutting precise and special threads. To obtain an increased feed or right-hand thread, a gear block is provided located in the gearbox. The body of the feed box has 2 longitudinal bores, in which the shafts are mounted on rolling bearings. The gears are made of chromium steel and hardened. The choice of feed rates is carried out by two handles by moving the gear blocks. The choice of the type of thread or the inclusion in the feed is also carried out by handles. To turn on the screw directly, handle 5 must be put in the "metric thread" position, handle 1 - in the "screw directly" position, handle 8 - "lead screw" (see control diagram Fig. 6; 7).

Lathe shift mechanism 163
Gear change mechanism. The inclusion of any of the 24 spindle speeds is made on the machine model 163 with two handles.
Handle 1 (Fig. 23, b) controls the movable blocks of gears B1 and B2 (Fig. 22, a) of the gearbox, and handle 27 (Fig. 23, b) controls the triple block B3 and double block B4 (Fig. 22, a ) of the sorting device.
By rotating the handle 1 (Fig. 23, b), through the shaft 26 and gears 25-8, the crank pin 9 and the disk 7 with an end curved groove a, which includes the roller 6 of the two-arm lever 5, are set in motion. The second end of the lever 5 is connected by means of the slider 32 with fork 31 moving along a circular guide 30. Fork 31 controls the triple movable block B2 (Fig. 22, a).
The crank pin 9 (Fig. 23, b) with the help of the slider 10 moves the fork 11 along the round guide 12, which controls the double movable gear block B1 (Fig. 22, a).
Each of the six fixed positions of the handle 1 corresponds to a certain arrangement of double and triple gear blocks, which provides six combinations of gear engagement and, accordingly, six different spindle speeds.
The casing 2 has six windows e, through which the numbers printed on the disk 3 are visible. The numbers correspond to a series of spindle speeds. Pointer d on the limb of the handle 1 shows what number of revolutions the spindle will have with a given arrangement of handles 1 and 27.
When the handle 27 is turned through the shaft 21, the gear train 20-19-18 and the shaft 17, the disk 16 is rotated. The latter has curved end grooves c and d and V-shaped recesses - b. Forks 24 and 23 are installed on the round guide 22. The curved groove in through the fork 24 determines the position of the triple movable gear block B3 (Fig. 22, a), and the groove d with the help of the fork 23 (Fig. 23, b) moves the double movable gear block B4 (Fig. 22, a).
Notches 6 (Fig. 23, 6) serve to fix the position of the gear blocks. For this purpose, a retainer is provided, consisting of a ball 15, a spring 14 and a threaded plug 13.
The disc 3 is connected to the shaft 21 by means of a lever sleeve 4, a link 29 and a lever 28. Therefore, each fixed position of the handle 27 corresponds to a certain position of the disc 3 with numbers of spindle speeds.

Control of the main drive of the machine 163
Starting the main motor is carried out by pressing one of the "Start" buttons - 1KU, 2KU (located on the apron near the feed box), which closes the power supply circuit for the coils of the magnetic starter KSh and the IPB time relay (4-13). The coils, under the influence of the current passing through them, attract the core of the armatures and close the main contacts and auxiliary contacts mechanically connected to them. At the same time, the main contact KSh connects the 1D electric motor to the network, and the starter coils and the time relay are powered through the closed auxiliary contact KSh (1-5), which eliminates further pressing the "Start" button.
Simultaneously with the coils of the starter KSh and the time relay IPB, through the closing block contact IPB (17-23), the time relay RV will be energized. If the friction clutch is not transferred to the working position within the time for which the PB relay is set, then the latter, with its opening contacts PB (2-4), will de-energize the coil of the magnetic starter KSh and the time relay 1PB, followed by stops of the electric motor 1D. When the RV coil is turned off, the closing contact (45-V7) connects the 5EM brake electromagnetic clutch and the 2LS signal lamp. The stop of the main engine 1D is carried out by pressing one of the "Stop" buttons - 3KU, 4KU, located on the carriage and near the feed box.
Control of electric pumps 2D is carried out by means of a VT-2 toggle switch located on the side wall of the electrical cabinet.
