Notch 13 with shoulders 14 provides the direction of movement of the part 6 when fed to the cutting tool and its fixer from the action of the cutting forces during machining. The machining of the part 6 is carried out by the cutters 15 (machining the inner surface), 1b (removing the outer facet) and 17 {tightening the inner chamfer).

Sn t le chamfers are produced at the same time. Part 6, when it is fed, protrudes from recess 3, for a cut of the base 1, no more than half its width.

On the lopue of the front part of the base 1, adjacent to the recess 13, B1 is a chamfer 18, the angle K I Rooi is equal to the angle of the outer face

The front part slider 19 i is made semi-cylindrical with a radius less than the outer radius of the det / .and 6, and on the rest of the first part - the ir - motive. in the front part of the pose 19, there is an inner semi-cylindrical seat 22, the radius of which is larger than the inner radius of the part 6. This slot serves for the 15 mandrel 23 after machining the inner (:) surface of the part 6.

Outside and slider 19, the cross-section H1) 1 Г G1p is a carbon-shaped patch 24. It provides a passage for the narrow part 1: iber 7; when it is moved to its original position, when the crawler 1 11a is in the green () working position).

The rezts5.1a mandrel 2i3 with the incisors 15-17 fixed in the 1st is fixed on the spindle 35 of the machine tool.

The boot device operates as follows.

In the adjustment mode, the tray 2 is loaded with parts 6 in the oriented position and the power cylinder 4 is turned on. At that time, the pins 6 are pushed against the vertical wall of the main shaft 1. The front part 6 is located in the semicircular notch of the gate 7.

The power cylinder 29 is turned on. A current of 30, acting on the traverse L 8, and last on the guide columns 27, presses the cylinder 20 with a bottom 32 to the adjusting screws 34.

The spindle drive 35c re is activated; with a mandrel 23 of the machine tool. The mandrel 23 with incisors 15 to 17 rotates about an axis.

When the cylinder 8 is turned on, the gate 7 moves to the left and moves the part 6 to the feed line to the working zone (into the gap between the slider 19 and the cylinder 2 (5)

The ram 20 is engaged. In so doing, the slider 19 moves to the left.

Since the force of the power cylinder 20 significantly exceeds the force of the power cylinder 29, the slider 19 presses the part 6 to the cylinder 26 and with it moves along the recess 13 with the shoulders 14. The inner surface of the part 6 is machined with a cutter 15.

Upon further movement, part 6 partially leaves (no more, Mt; M on
