Description

(54) ROTARY DEVICE

The invention relates to the field of machine tools, namely to vehicles of automatic lines and machine tools.

Turning devices (rotary drums, rotary tables, etc.) are known, into which the part is fed by the conveyor of the previous section of the automatic line, and is picked up by the conveyor of the subsequent section of the automatic line 1.

However, in this case, the productivity of the automatic line decreases, since the conveyors of the previous and subsequent sections must operate in a strictly defined sequence, as a result of which the downtime and delays of one section are completely superimposed on. the work of the adjacent area.

To eliminate this drawback, the part from the orienting device is provided by the pusher, which ensures the separation of the work of conveyors of adjacent sections.

These pushers, made in the form of a hydraulic cylinder, require large production areas.

The closest to the proposed technical entity is a swivel device containing a fixed housing with a rotatable part and Toai-caievieM

to move the workpiece, equipped with a drive 2.

Installing the pushers directly into the rotary device, although it provided some reduction in the production area, iHO required more complex operation and, accordingly, an increase in the number of control equipment, which in turn led to a decrease in the reliability of the automatic line.

The purpose of the invention is to simplify the design, reduce the production area and increase reliability.

This goal is achieved by the fact that

15, the pusher is made in the form of a chain open loop with two branches arranged in guides, one of which is made on a fixed housing and the other in a rotatable part.

The pivoting device comprises a fixed casing 1 with a pivoting part 2 and a pusher 3 for moving the machining body 4, equipped with a reversible

The pusher 3 is made in the form of a chained open Loop, both branches 7 and 8 of which are located in guides, one 9 (stationary) of which is mounted on the housing 1, and the other 10 (movable) in the rotary part 2,

The branch 8 of the chain is equipped with a dog 11, moving the workpiece 4.

The device works as follows

During the operation of the automatic line, the work piece 4 enters the rotator. After turning, the mobility guide 10 is located opposite the fixed guide 9 of the pusher. At this moment, the dog 11 is in the lower part of the fixed guide Q.

After the command to push the part 4 is pushed, the dog I goes into the movable guide 10 and takes the leftmost position. Next is the reverse of the drive 5 sprocket 6 and the dog 11 pushes the workpiece 4 from the rotator. Then the cycle is repeated.

Execution of the pusher in: a form of an open chain contour, both branches of which are located in the movable and stationary guides, and 1 with its reversible drive allows the device to be built in any part of the automatic

liyiyu, significantly reducing the production area.

Placing the pusher outside of mobile devices allows to increase the reliability of the LINE, while ensuring the separation of the work of conveyors of adjacent areas, i.e., to increase the productivity of the automatic link.
