Safety protection type automatic clamping mechanical hand

Abstract

The invention discloses a safety protection type automatic clamping mechanical hand, and mainly relates to the technical field of mechanical hands. The two ends of a first joint shaft are separately connected to a machine body and a second joint shaft in a matched manner; the first joint shaft, the second joint shaft and clamping fingers are driven by a servo motor arranged inside the machine body; the upper end of a piston rod is connected to an air cylinder in a matched manner through a buffer mechanism, the lower part of the piston rod passes through a second joint arm, and is nested in a sealing sleeve, and the bottom of the piston rod is fixedly connected to a shaft coupler; the clamping fingers are connected to the shaft coupler in a matched manner through connecting rods; magnetic blocks are inlaid inside the end parts of the clamping fingers; the surface of the second joint shaft is provided with a detecting device connected to an audible and visible alarm; and paint is coated on the surfaces of the clamping fingers. The mechanical hand disclosed by the invention is small in damage on a workpiece, is good in integral safety, can guarantee efficient and stable operation of clamping work, has fewer redundant structures, is very convenient to mount, dismount and maintain, and is low in manufacturing and operation cost.

Description

technical field [0001] The invention relates to the technical field of manipulators, in particular to a safety protection type automatic gripping manipulator. Background technique [0002] A manipulator is an automatic operating device that can imitate certain movement functions of the human arm to grab, carry objects or operate tools according to a fixed program. The manipulator is the earliest industrial robot and the first modern robot. It can replace the heavy labor of people to realize the mechanization and automation of production, and can operate in harmful environments, so it is widely used in machinery manufacturing, metallurgy, electronics, light sectors such as industrial and atomic energy. Among them, the gripping manipulator generates power through electric or pneumatic means to replace frequent manual grabbing actions, which reduces the work intensity of personnel to a certain extent. [0003] In recent years, with the continuous development of science and te...

AI Technical Summary

Problems solved by technology

[0004] 1. The axial impact force generated when the piston rod goes down can easily damage the workpiece;

[0005] 2. The overall safety is poor, and it cannot respond in time when an unexpected situation occurs, and cannot guarantee the efficient and stable operation of the gripping work;

[0006] 3. The manipulator has many redundant structures, large size and weight, high load requirements, cumbersome maintenance, and high manufacturing and operating costs
