The invention relates to a machine tool industry, in particular, to an aggregate meta-spacing machine with satellite devices, and is intended for machining parts such as rotary bodies weighing more than 100 kg,

The purpose of the invention is to expand the technological capabilities and improve the accuracy of processing due to obdg- | n liver ability to install on the installation of equipment pre-oriented heavy.

On presented the proposed machine, a general view; in Fig.2, js view A in Fig. 1; on fig.Z view B on fig, 1; Fig, 4 - section bb In Fig.Z.

The aggregate machine contains a multi-position rotary table 15 having 20 SCH1-W loading positions 2, processing positions 3-6 and a free position 7. Part 8 is transferred from position to the machine by table 1 in the installation position.

satellite fixture 9, in which 25 part 8 can occupy vertically

three positions: -1 - the loading position and unloading; II - position, location of part 8; III - position of the carriage outlet, the distance between which the ZO

respectively A and

In satellite 9, the part installs- C on the base hole D on two fixed rigid base elements.

10, 11, placed through 120 ° at the periphery of the nominal processed

position Us and spread by a movable clamp 12a with drive 13 and pusher 14 "

In the angular position, the part 8 is fixed in diameter d by means of a clamp 15 placed in the housing 16. And equipped with a handle 17

in motion In satellite 9, the basic strips IS are placed, to which the part 8 y is pressed by the rotary L-shaped

bayonet tacks 19,

Boot device completed

in the form of a drive carriage 20 moving to the ground for moving L with rollers 21J 22 along guides 23 mounted in bracket 24.

On the carriage 20, there is a mechanism for preliminary fixation, which is extraordinary in VI, a rocker arm 25 with a special vertical otunzher 26, spring-loaded with respect to the carriage 20 by springs 27; and two one-arm levers 28, turning relatively

axis 29. The force of the two springs 27 exceeds the weight of the part 8 by 10-15 kg. The levers 28 are provided with a 30 return position. The arms of the levers 28 are mounted freely: on the rotating rollers 31, on which the part 8 is mounted, while the levers 28 interact with the plungers 26.

The carriage 20 is equipped with a shaft 32 with an eccentric cam 33 and its rotation handle 34 having three fixed positions when rotated 45. A limiting jog 35 is mounted on the shaft 32, and a side offset plate 36 of the part 8 is mounted on the bracket 37 Eccentric cam 33 shaft 32 interacts with the rocker 25 through the spacer 38 and the compensator 39.

Aggregate machine works as follows.

The force of the two springs 27 through the plungers 26 and the levers 28 forces the machined piece 8 in position 1 (Fig. 2), and the plungers 26 will not be able to lift up, having a strict limitation in the form of a rocker arm 25 connected through the compensator 39 and bet 38 with eccentric 33, After loading the workpiece 8, the carriage 20 makes the movement of L using rollers 21, 22.

Carriage stroke (FIG) - along the guides mounted on the bracket 24,

At the end of the turn. L, the workpiece 8 is pressed against the base slats 18 of the fixture-satellite 9 mounted on the turntable 1, and the carriage 20 is fixed in the forward position

The workpiece 8, located vertically in position 1 (Figures 1 and 4), has a guaranteed clearance C (FIG. 3) between the base hole D and the two rigid latches 10 1K located 120 ° around the periphery of the first position II. base hole D,

By turning the handles 34 and 45 °, the hoist 8 through the cam-eccentric gear 33 - spacer 38 - compensator 39 - rocker 25 - shgunger 26 lowers a (a) (fig. 3), completely selecting the gap C, while remaining on rollers 31 due to the spring in suspension, which greatly facilitates turning

the part to be machined, necessary for carrying out its angular fixing on the diameter d with the help of a sheared retainer 15, moved by the mechanism located in the body 16 by means of the handle 17, after which the final part of the workpiece 8 is misaligned along the base hole D with the help of d water 13 through the pusher 14 fixed in the fixture 9 by the lever 12, which is the third base point (along with two rigid stops 10, 11), providing the nominal position (II) of the workpiece 8 in the fixture 9. After this, part 8 is clamped by hydraulic cylinders c. 19. By turning the knob 34 another 45 ° shaft 32 with 20 eccentric 33 pulls the rollers ZG by the value of L-sin 45 °, while simultaneously withdrawing the clamp 35 attached to the shaft 32 from the area of the workpiece 8, the carriage 20 unlocks - 25 is reset.

The turntable 1 rotates one division, thereby feeding to the loading position 2 the already machined part 8 from the 6th position of the workshop, which is removed into the carriage 20 brought in and fixed in reverse order and transported in it to the workshop conveyor and replaced by new non-g

working detail 8.
