Mechanical arm capable of adjusting grip strength

Abstract

The invention discloses a mechanical arm capable of adjusting grip strength. The mechanical arm comprises a fixing rod, a clamping mechanism, a transmission mechanism, a fixing mechanism, an adjusting mechanism and a rotating mechanism, wherein the fixing rod is respectively connected with the clamping mechanism, the fixing mechanism and the rotating mechanism; the clamping mechanism is respectively connected with the transmission mechanism, the rotating mechanism and the adjusting mechanism; and the clamping mechanism is movably arranged at the bottom of the fixing rod through a rotating shaft. According to the mechanical arm, the adjusting mechanism is arranged, the position of a installation block can be moved by rotating the installation block in the installation hole, therefore, the distance between a first electromagnet and a second electromagnet can be changed, the movable distance of a supporting plate can be changed when goods are clamped, and the gripping force for clamping products can be adjusted.

Description

technical field [0001] The invention relates to the technical field of manipulators, in particular to a manipulator with adjustable grip strength. Background technique [0002] A manipulator is an automatic operating device that can imitate certain movement functions of the human hand and arm to grab, carry objects or operate tools according to a fixed program. It is characterized in that it can be programmed to complete various expected operations. Combining the advantages of man and manipulator, 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 to protect personal safety. Therefore, it is widely used in machinery manufacturing, metallurgy, electronics, light industry and atomic energy and other departments. [0003] There are following deficiencies in existing manipulators: [0004] 1. The existing manipula...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing manipulator cannot adjust the strength of the manipulator to grip the product well when it is in use. When grabbing different products, it needs to use different grip strengths, and the current manipulator does not have a buffer device. When grabbing the product, it may cause damage to the product;

[0005] 2. The existing manipulator cannot be rotated very conveniently, it is very inconvenient when picking and placing the product, and it is very troublesome to use
