Description

The invention relates to the field of engineering and can be used in flexible production systems. The aim of the invention is the expansion of technological capabilities of vacuum capture. For this, a vacuum gripper comprising a housing

1 with a vacuum chamber 2, a vacuum conductor 3 and holes 10, is equipped with a mechanical spool 4 with teeth 5 and holes 11 with bridges 13, and in the vacuum wire 3 there is an additional impeller 7 with a shaft 6 on which the bevel gear 8 is fixed The holes 10 and 11 are made so that at any position of the mechanical spool 4 at least one of the holes 11 communicates with one of the holes 10. When the device passes through the holes 10, 11, the air presses on the web 13, lifting the front spool 4. When This rotation of the impeller 7 The rotation of the face spool 4, which is rotated until all the holes 10, not covered by the captured part, will not be blocked by it. 4 il.

The invention will lean towards mechanical engineering and can be used in flexible production systems when working with complex parts,

The aim of the invention is the expansion of technological capabilities of vacuum capture.

FIG. 1 shows the device „general view; in fig. 2 is a section A-A in FIG. 1; FIG. 3 is a section BB in FIG. one; in fig. 4 - section B-B in FIG. one,

The device includes a housing 1 and · a vacuum chamber 2, a vacuum wire 3, mounted on the housing 1. On the vacuum line 3 with limited axial displacement and rotation, there is an end spool 4 with teeth 5, In the vacuum wire 3 on the ram 6 an impeller 7 is installed and a bevel gear 8 forming together with the teeth 5 a mechanical gear. A rubber gasket 9 is installed on the working surface of the housing 1, and holes 10 are made. Holes 11 are made in the face spool 4, connected to the vacuum pipe 3'channels 12, jumpers 13 are fixed to the walls of the holes 11. at any position of the face spool 4, at least one of the holes 11 communicates with one of the holes 10 in the housing 1 "

The device works as follows.

When connecting the vacuum wire 3 to the vacuum source through the holes 10 and 11 and the ducts 12. air enters, Under the pressure of air on the bridges 13, the front spool 4 'comes off the body and starts to rotate due to the rotation of the impeller 7 transmitted by the shaft 6 gears 8 and teeth 5, When

This hole 10 in the housing 1 and the holes 11 in the front spool 4 are moved relative to each other. When lowering the grip on a part having holes or notches, the face spool 4 rotates until all the holes 10 not covered by the part are blocked by the face spool 4. At the moment when all the holes 10 are blocked by the part or face spool 4, the flow air through the holes 11 will stop, at the same time the face slide 4 will simultaneously lower and the impeller 7 will stop rotating, the part will be captured. After transferring the part to the working position, the vacuum source is disconnected and the part is disconnected.

Claims (1)

Claim Adaptive vacuum grip, comprising a housing with holes on the working surface, a vacuum chamber, a vacuum wire fixed to the housing, and an opening overlap mechanism, characterized in that, in order to expand technological capabilities, the opening overlap mechanism is in the form of an end spool with the holes connected to the vacuum-wire by the corresponding channels, and bridges are fixed on the walls of the holes of the mechanical spool, and an additional wire is installed inside the vacuum wires (the impeller with the shaft is connected m mechanical transmission with mechanical slide valve mounted in a vacuum chamber at a vacuum wire for limited axial movement and rotation of the posts to secure the housing and the corresponding holes of the mechanical valve. 1484718 1484718 AT 8 Fy
