A double clamping mechanical gripper device

Abstract

The invention discloses a dual clamping mechanical catching hand device which comprises a cylinder body, a piston rod assembly, a clamping catching hand and a tightening assembly. The cylinder body is assembled on a transfer device of a mechanical catching hand, and the clamping catching hand is assembled on the piston rod assembly through the tightening assembly. A first catching hand clamping section and a second catching hand clamping section are provided with strip-shaped grooves, and the sections of a third catching hand clamping section and a fourth catching hand clamping section are of an L-shaped structure. Primary clamping in dual clamping of the mechanical catching hand device is the clamping and capturing of an operated workpiece through the strip-shaped grooves of the first catching hand clamping section and the second catching hand clamping section, the secondary clamping is auxiliary supporting and auxiliary clamping of the operated workpiece through the L-shaped structures of the third catching hand clamping section and the fourth catching hand clamping section, and the problems that the operated workpiece is not clamped firmly, sliding and even dropping occur in the transfer process and the placing position is inaccurate are solved. The dual clamping mechanical catching hand device is simple in structure, reliable in principle and convenient to implement, and the operated workpiece is high in reliability in the clamping, capturing, transferring and placing process.

Description

[0001] Technical field [0002] The invention relates to the technical field of a mechanical gripper device for a robot, in particular to a double-clamping mechanical gripper device for a small robot. Background technique [0003] In the wide application of robots, the function of the mechanical gripper is to complete the clamping, grasping, moving and placing of the workpiece, which is one of the key components in the robot. The structure of the mechanical gripper device of a small robot is usually a pair of clamping grippers, and the clamping, grasping, moving and placing of the workpiece are completed through the relative clamping of the gripping sections of the grippers. [0004] At present, when the mechanical gripper device of a small robot clamps, grasps, moves and places the workpiece, the gripper clamping section has a small contact area due to the small workpiece being operated, and there are large processing errors, resulting in gripper clamping. The contact surfac...

Problems solved by technology

[0005] In order to overcome the fact that the existing mechanical gripper device of a small robot clamps, grasps, moves and places the workpiece, the gripping section of the gripper has a small contact area due to the small workpiece to be operated, and there is a large processing error that causes the gripping The contact surface of the hand clamping section is uneven, and some operating workpieces have restrictions on the clamping force due to material problems, etc., which may cause unreliable clamping of the operating workpiece, slipping or even falling during the moving process, and inaccurate placement; To a certain extent, defects such as the normal operation of the production line of such operating workpieces are affected, and the present invention provides a new double-clamping mechanical gripper device
