AI Technical Summary

Technical Problem

When the clamping and conveying robot arm in the prior art is driven pneumatically, the clamping jaws are loose due to unstable air pressure of the air source, and the workpiece clamping force is insufficient, which affects the conveying efficiency.

Method used

A clamping conveying robot arm is designed, adopting a structure of servo cylinder, shell and clamping jaws. The middle part of the clamping jaws is provided with a rotating groove, and the inner wall is rotatably connected with a rotating shaft. The hollow magnetic suction plate is driven to move through the lever principle. Combined with the design of the spring plate and the magnetic suction plate, the connection stability of the clamping jaws is enhanced.

Benefits of technology

It effectively prevents the cylinder output shaft from sliding due to unstable air pressure of the air source, avoids loose claws, ensures that the workpiece is always fixed in the claws, prevents falling, and improves conveying efficiency.

Abstract

The utility model belongs to the technical field, and particularly relates to a clamping and conveying mechanical arm which comprises a servo air cylinder, a shell and a clamping jaw, a rotating groove is formed in the middle of the clamping jaw in a penetrating mode, a rotating shaft is rotatably connected to the inner wall of the rotating groove, and a first connecting plate is fixedly connected to the outer wall of the rotating shaft. A second connecting plate is fixedly connected to the position, located on one side of the first connecting plate, of the outer wall of the rotating shaft, a hollow magnetic suction plate is fixedly connected to one end of the second connecting plate, sliding plates are symmetrically and slidably connected to the interior of the clamping jaw, and a third connecting plate is jointly and fixedly connected to one ends of the two sliding plates. In the process that the mechanical arm clamps and conveys a workpiece, unstable sliding of the output shaft of the air cylinder caused by unstable air pressure of an air source and insufficient clamping force caused by loosening of the clamping jaw can be prevented, so that the workpiece can be fixed in the clamping jaw all the time and is prevented from falling off, and the conveying efficiency is improved.
