AI Technical Summary

Technical Problem

In the prior art, the turn-over seat of the mechanical claw module is not provided with a limiting device, which causes the hydraulic cylinder to expand and contract under a static pressure due to external force during the transfer or installation process after clamping the electric rod, affecting the life of the oil cylinder.

Method used

A mechanical claw module rotary rotary dial with a self-locking mechanism is designed. By setting two engagement rotary dials and limiting parts, the limiting part is extended into the socket after clamping to lock the hinged position of the end of the hydraulic cylinder to ensure that the hydraulic cylinder remains stable under static pressure.

Benefits of technology

It effectively prevents the expansion and contraction of the hydraulic cylinder due to external force under static pressure, extends the life of the oil cylinder, and improves the stability of the mechanical claw module during clamping and transport.

Abstract

The utility model discloses a mechanical gripper module rotating turntable with a self-locking mechanism, which comprises a rotating seat, a left shaft seat and a right shaft seat are arranged on the rotating seat at intervals, a first rotating shaft is inserted on the left shaft seat and the right shaft seat, the end part of a hydraulic cylinder is connected with the first rotating shaft, one end of the first rotating shaft extends out of the left shaft seat and is provided with a first turntable with teeth, and the other end of the first rotating shaft is provided with a second turntable with teeth. A second rotating shaft is further arranged on the left shaft seat, one end of the second rotating shaft extends out of the left shaft seat and is provided with a first rotating disc with teeth, the first rotating disc is meshed with the second rotating disc, an inserting hole is formed in the inner end of the second rotating disc, and a limiting tooth groove is formed in the side wall of the inserting hole; the limiting piece can slide to extend into the inserting hole to be matched with the limiting tooth groove for limiting. According to the scheme, the two meshed rotating discs are arranged, and when an angle needs to be kept after clamping, the limiting pieces stretch into the inserting holes to be locked, so that the hinged position of the end of the hydraulic cylinder is locked, and enough stability of the hydraulic cylinder can be guaranteed even under static pressure.
