Workpiece transposition manipulator of hydraulic stretcher

Abstract

The invention belongs to the technical field of manipulators, and particularly relates to a workpiece transposition manipulator of a hydraulic stretcher. The workpiece transposition manipulator comprises a rotating motor and an auxiliary rotating arm, and the auxiliary rotating arm is fixedly installed at the output end of the rotating motor; a clamping piece is fixedly installed on one side of the auxiliary rotating arm, and comprises a rotating shaft and two clamping arms; two anti-falling assemblies which are symmetrically distributed are arranged in the clamping arm; after a workpiece is clamped through the two clamping arms, the two anti-falling assemblies are rotated in the opposite directions under the action of the driving piece, and the clamped workpiece is clamped for the second time; the contact area between the clamping piece and the workpiece is increased; therefore, the friction force between the clamping piece and the workpiece is increased, so that the clamping and fixing effect of the clamping piece is better; the contact surface between the workpiece and the clamping piece is increased, and the situations that the contact surface between the workpiece and the clamping piece is small, the local pressure is large, and the exterior of the workpiece is prone to being damaged are effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of manipulators, and in particular relates to a work piece transposition manipulator of a hydraulic stretching machine. Background technique [0002] In today's life, with the rapid development of science and technology, the biggest difference between a robot arm and a human arm lies in its flexibility and endurance, that is, the biggest advantage of a robot arm can repeat the same action under normal mechanical conditions Under the circumstances, the application of the robot arm will become more and more extensive. The robot arm is a high-tech automatic production equipment developed in recent decades. The accuracy of the operation and the ability to complete the operation in the environment are one of the industrial manipulator robots. important branch.

AI Technical Summary

Problems solved by technology

[0003] The Chinese patent discloses a workpiece transposition manipulator for a hydraulic stretching machine (authorized announcement number is CN206795818U). Adjust the up and down height of the manipulator installation sleeve, so as to control the up and down height of the manipulator assembly; the tightening and loosening of the left manipulator and the right manipulator are controlled by the cylinder, but the existing left manipulator and right manipulator are tightening due to the contact with the workpiece The clamping surface of the manipulator is small, and after the manipulator is clamped and rotated, it is easy to cause the workpiece to fall from the manipulator, which affects the normal operation of the manipulator. Therefore, those skilled in the art provide a hydraulic stretching machine workpiece transposition manipulator , to solve the problems raised in the above background technology
