Problems solved by technology

Most of the existing manipulators have two claws, and there are only two contact points when grabbing cylindrical objects, which is not reliable, and the objects are prone to slipping, which affects work efficiency
Three-claw manipulators are gradually appearing on the market, but most of them have complex structures, irregular shapes of parts, and complicated production processes, which undoubtedly increase production costs.

Abstract

The invention discloses a three-jaw manipulator formed by three crank-slider mechanisms. The three crank-slider mechanisms are equidistantly and circumferentially distributed on a mother disc and share a crank, each crank-slider mechanism is composed of a finger slider, a connecting rod, a mother disc and a turntable, the finger slider of one of the crank-slider mechanisms is connected with an air cylinder through which opening and closing of fingers are realized, and three fingers can simultaneously slide centripetally or centrifugally and can realize centering of cylindrical workpieces.

Description

technical field [0001] The invention belongs to the technical field of manipulator manufacturing, and relates to a three-jaw manipulator composed of three sets of crank slider mechanisms. Background technique [0002] With the advancement of productivity and the popularization of production automation, manipulators play an important role. Most of the existing manipulators have two claws, and there are only two contact points when grabbing cylindrical objects, which is not reliable, and the objects are prone to slipping, which affects work efficiency. Three-jaw manipulators are gradually appearing on the market, but most of them have complex structures, irregular shapes of parts, and complicated production processes, which undoubtedly increase production costs. [0003] Contents of the invention [0004] The object of the present invention is to overcome the defects of the prior art, and provide a three-jaw manipulator with simple structure and accurate grasping, which is...
