Abstract

The invention discloses a robot gripper device for clamping special-shaped workpieces. The robot gripper device for clamping special-shaped workpieces comprises a mounting base, a first bracket, a second bracket, a third bracket, a motor, a connecting rope and a fixed seat. A columnar cavity is formed in the fixed seat; a second connecting pipe is inserted into the columnar cavity; a first connecting pipe is connected below; two inserting rods are arranged above the first connecting pipe; a second spring is connected between the inserting rods; a first annular pipe is connected through below the inner part of the first connecting pipe; a second limiting ring is fixedly connected to the bottom of the first annular pipe; a first annular strip is inserted into the first annular pipe; the first annular strip is fixedly connected to a first piston; a clamping block is hinged below the first connecting pipe through a hinge; a first glue block is connected to the inner side of the clamping block; a second glue block is fixedly connected to the inner side below the first glue block; and a third spring is connected between the clamping block and the first connecting pipe. The robot gripper device disclosed by the invention can improve defects in the prior art, and can clamp workpieces of different shapes more firmly.

Description

technical field [0001] The invention relates to a robot gripping device, in particular to a robot gripper device for gripping a special-shaped workpiece. Background technique [0002] With the continuous development of science and technology and the decline of the demographic dividend, labor costs are getting higher and higher. In order to save costs and improve production efficiency, more and more companies are transforming their production and starting automation equipment to replace existing manual operations; automation Operation can not only reduce labor costs, improve production efficiency, improve product quality, but also facilitate production management. In automated production, robots and manipulators are frequently used. Chinese invention patent CN 203380896 U discloses a pneumatic series flexible hinge multi-finger gripper with a compliant mechanism. The robotic gripper with this structure has good flexibility and cushioning performance for external loads, and ...
