A kind of robot arm with replaceable gripper

Abstract

The invention relates to the technical field of machine arm equipment for auto parts, in particular to a gripper replaceable machine arm. The gripper replaceable machine arm comprises a clamping jaw air cylinder, a clamping jaw, a mounting block, a fixed sleeve, a column section, a circular truncated cone section, a cone groove, a clamping hole, a notch, a micro air cylinder, a limiting block, a connecting column, a clamping jaw bracket, a clamping block and a V-shaped groove. The gripper replaceable machine arm has the beneficial effects that when the clamping block is mounted, the connectingcolumn is locked to the clamping hole of an elastic chuck and then the micro air cylinder acts, so that the limiting block pulls the column section to slide in a blind hole in the fixed sleeve, and the circular truncated cone section slides in the cone groove. As the notch is formed in the circular truncated cone section, the outer wall of the circular truncated cone section shrinks elastically toward the radial inner side of the circular truncated cone section, so that the inner wall of the clamping hole clamps the connecting column, so that the clamping bloc is mounted quickly. Therefore, the replacing speed of the clamping block is improved to at least a certain extent, so that the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of robotic hand equipment for auto parts, in particular to a replaceable gripper robotic arm. Background technique [0002] Shaft parts are commonly used parts in auto parts. During processing, the turnover of shaft parts usually needs to be grasped and transferred by machine grippers to realize the turnover of shaft parts. The existing machine grippers are generally made of The jaw cylinder is composed of jaws. The action of the jaw cylinder makes the two jaws relatively close to each other, and then grabs the shaft parts. However, the current jaws are inconvenient to install and disassemble. When replacing the jaws of a specific product model, it needs to be shut down for a long period of time, and then replaced by workers. Due to the long downtime, the production efficiency will be reduced. Contents of the invention [0003] The purpose of the present invention is to overcome the problems existing in t...
