The invention relates to mechanical engineering and can be used for two-sided machining of parts, for example, the type of cable connector jacks. The aim of the invention is to expand the functionality of the machine by providing clamping of parts when the turntable is rotated. FIG. 1 schematically shows a machine for two-sided processing of parts; in fig. 2 is a view A of FIG. 1. The machine contains a base 1, on which a rotary table 2 is mounted with clamping devices, each of which is made in the form of a lever 3 spring-loaded relative to the rotary table 2, hinged on the axis 4, mounted on the lower end 5 of the rotary table 2 and the fixed lolsement formed The inner wall 6 is made in the recess 7 of the turntable 2. The spring-loaded lever 3 with one side enters the corresponding notch 7 of the turntable 2, forming a receptacle for the part 8 and a socket. On the second side of the spring-loaded lever, the roller 9 is fixed on the axis. Coaxially the rotary table 2 is equipped with an annular face copier 10 that controls the clamping device and releases the part 8. A spring 11 is attached to the end 5 of the rotary table 2, which pushes the spring-loaded lever 5 away from the lodgement. A spring 13 is fixed on the machine body 12 to securely clamp the workpiece 8 in the cradle, for example, when there are deviations in its dimensions. A copier 14 is installed outside the side surface of the rotary table, controlling the change in position of the parts 8 in the cradle. A stopper 15 is fixed under the cradle in the loading area, preventing the workpiece 8 from falling out of the cradle.

The spring-loaded lever 3 is made L-shaped for the convenience of bringing the tools into the treatment area. In the walls of the notches 7 of the rotary table 2 and the spring-loaded lever 3 fixed coaxial spring-loaded fingers 16, Ha, two machine-wheels 17 are mounted opposite the machine body,

The rotary table drive consists of the Maltese mechanism 18, the electric motor 19, the gearbox 20 and the chain transmission 21. In addition, on the base 1 the loading device 22 is mounted, the threaded head

five

23, two blocks 24 and 25 for milling.

Machine for two-sided machining works as follows.

From loading device 22, part 8 is fed into a receiving slot and held in it at the initial moment by a limiter 15. When the turntable rotates, the roller 9 of the spring-loaded pin 3 runs around the annular copier 10, turns it, and the latter presses part 8 to the wall 6 of the notch 7. With successive Turning the turntable 2, part 8 is fed to the thread-cutting head 23, where a thread is cut on it, then to blocks 24 and 25 for milling flat. Between the blocks 24 and 25, the profile of the ring copier 10 is changed.

The spring 11 presses the spring-loaded lever 3, the part 8 is released, lowered and slides the lower end of the copier 5 along 5, to obtain a radial upward movement. Conditions are created for machining the second end of the part 8 - milling the groove. After that, the roller 9 again rotates the spring-loaded lever 3, which again presses the item 8 to the wall 6.

Upon further rotation of the turntable 2, part 8 passes under the rollers 17, which, affecting

spring-loaded fingers 16, produce a sim card of the part 8, then the processed part 8 is released and falls into the drive,
