(54) MULTI-POSITIONAL UNIT FOR MACHINE

I2

The invention relates to a machine tool industry, namely to multi-position machines for machining holes in small parts.

A multi-position aggregate machine is known, comprising a frame, circumferential power heads, a pivoting device and floating satellites consisting of a body carrying clamping elements and fingers fixing the satellite relative to the power head. In the well-known machine, to ensure accuracy of fixation, interchangeable composite devices are used. The satellites consist of a lower support plate and an upper flange plate fixed relative to the power head by means of a pin on the floating plate of the satellite device and the corresponding catcher on the power head 1.

The purpose of the invention is to simplify the design while ensuring high accuracy in positioning the workpieces relative to the processing tools.

The goal is achieved by the fact that a ring gutter is made on the bed, in which are freely placed

the devices are satellites resting on the upper edges of the gutter, and the transport-rotary device is made in the form of a vertical shaft with a fixed Hfcw at its top end with a disk carrying protruding protruding p.

10 the housing of the satellite device, the shaft being installed axially displaced, and at its lower end a rotating gear of the device with 15 face teeth is freely mounted and rigidly fixed, butt half coupling installed with the possibility of interacting with the front teeth of the rotational gear wheel devices.

25 positions

The machine has a frame 1, on which in the technological sequence are placed the power working heads 2, equipped with a transitional plate 30 of that 3.

Stationary is fixed to an annular groove guide 4, in which satellites 5, which consist of two elements: housing 6, the upper and wider part 7 of which is supported to the edge of the annular groove 4, are placed loosely with a certain gap. mounted on it clamping device 8 for blanks and pins 9. Both elements are fastened with pins 10.

In the housing 6 - the lower part of the satellite attachment, on the side facing the periphery of the machine, there is a conical socket, and on the frame there is a retainer 11, having a pin 12 with a conical front part facing the conical socket, in the housing 6 -satellite satellite holes are made in the annular groove 4. The number of latches 11 corresponds to the number of satellite devices 5 in the groove 4.

On the upper part of the shaft 13 of the noBopoof-ci machine, the rotary transport disk 14 is fixed, carrying elastic forks 15 extending protruding on the periphery. The flat teeth of the fork encompass the satellite 5 and enter the corresponding cuts in the upper part of the housing 6.

The lower end of the shaft 13 is coupled with the transport of the rotary device, including two pneumatic cylinders (not shown), one of which rotates the disk 14 by means of a toothed rack 16 and a shaft 17 that is freely mounted on the shaft 15 of the shaft 17. em a half coupling. H the lower end of the Nala 13 is rigidly fixed to the second coupling half 18.

Aggregate machine works as follows.

When the disk 14 with forks 15 is rotated at a certain pitch, the latter capture devices-satellites 5, moving them along an annular groove 4, the upper edges of which serve as a support and sliding surface for the projecting part 7 of satellite satellites 5. Cutouts for the teeth of the forks 15 in the case of satellite satellites 5 are made with a gap in such a way that the satellites adapt freely to the processing positions.

The rotation of the disk is carried out in the following order. The air is supplied to the first pneumatic cylinder, and its joy is raised together with the VS 13 and the disk 14, as a result of which the forks 15 are released from the state pressed to the device by the m-satellites. Together with the shaft 13, the half coupling 18 rises and engages with the gear 17, the rail 16 moves from the second

pneumatic cylinder) performs turning gear, satellites 5.

For clamping the latter, the shaft 13 moves vertically downward from the piston 19 and opens the coupling half 18. The rail 16 returns from the pneumatic cylinder. To the starting position. With the lowering of the shaft 13 with the disk 14, the flat elastic teeth of the forks 15 press the satellites 5 to the guide surfaces of the groove 4. The conical pins 12 of the clamps 11 fit into the corresponding slots in the housings 6 of the satellite devices, fixing them in the exact position.

During the working stroke of the machining forces 5 {heads 2, the conic hole in the adapter plate 3 is lowered onto the pins 9 on the satellite devices, ensuring the rigidity of the tool-part system during machining. The machining tool is fed to a precisely calculated work place.

The adjustment of the machine is carried out as follows. At first, stitches 10 are fastened by both parts of the same satellite device 5. All power heads 2 are mounted on it, i.e. forming tools with respect to blanks. Next, the upper free-floating part of each next satellite fixture is precisely positioned relative to the processing tools, after which it is fastened with pins 10 to the body 6 of the satellite fixture. Thus, the installation of all the remaining satellite devices and, consequently, of the entire multi-station aggregate machine is carried out.

Such an implementation of the proposed aggregate machine allows to provide high accuracy of positioning and sturdy fixation of satellite devices with 3, pressed workpieces on them at work positions and eliminates the need to use more complex designs of turning tables and indexing mechanisms.
