Abstract

The invention discloses a manipulator fixture protection device. The manipulator fixture protection device comprises an air cylinder body, wherein a piston is arranged in the air cylinder body; an annular bypass port is formed in the side wall of the air cylinder body; the annular bypass port faces to an air inlet of the air cylinder body; a sealing piece is hinged in the annular bypass port, and the annular bypass port is connected with the air inlet of the air cylinder body through a connecting pipe; a first flow guide portion, a second flow guide portion and a third flow guide portion which are serially connected are arranged between the annular bypass port and the air inlet of the air cylinder body; the first flow guide portion is located on one side of the annular bypass port; the first flow guide portion is conical; the second flow guide portion is cylindrical and the third flow guide portion is elliptical. The manipulator fixture protection device can improve the defects of the prior art, can buffer the impact instantly born by a drive part and can protect the fixture.

Description

technical field [0001] The invention relates to the technical field of mechanical arms, in particular to a clamp protection device for a mechanical arm. Background technique [0002] On various processing and transmission robotic arms, it is often used as a clamping tool when clamping. Chinese invention patent CN101987435B discloses a fixture, after workpieces with different proportions are clamped, the center will not shift. However, when the clamp falls off unexpectedly, due to the continuous existence of the clamping force, the instantaneous impact force will cause irreversible damage to the driving parts of the fixture. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a clamp protection device for a mechanical arm, which can solve the deficiencies of the prior art, and can buffer the impact machine that the driving part is subjected to momentarily, and protect the clamp. [0004] In order to solve the above ...
