Novel light six-freedom-degree cooperative mechanical arm

Abstract

The invention provides a novel light six-freedom-degree cooperative mechanical arm. The novel light six-freedom-degree cooperative mechanical arm comprises a base and multiple joint bodies; one jointbody is fixed to the base, remaining joint bodies are assembled and formed, each joint body comprises a shell, a motor and a speed reducer, the speed reducers are fixed into the shells, output ends ofthe speed reducers penetrate the shells to be arranged outside, the motors are fixed into the shells, first synchronous belt wheels are arranged on output shafts of the motors, second synchronous belt wheels are arranged on the input ends of the speed reducers, the first synchronous belt wheels and the second synchronous belt wheels are connected through synchronous belts, the motors control theoutput ends of the speed reducers to rotate, the output end of the speed reducer of one joint body can be fixed to a through connection opening of the other joint body. Modular design is achieved, producing and making are easy, use is easy, high load / self weight ratio is achieved, the modular reconfigurable aim is achieved, and reliability is high.

Description

technical field [0001] The invention relates to a mechanical arm, in particular to a novel lightweight six-degree-of-freedom cooperative mechanical arm. Background technique [0002] A robot can generally be understood as: a programmable machine that completes certain operations and mobile operations through an automatic control area. People try to design this kind of machine to have certain functions of imitating humans or animals, and to expand and extend these functions to replace people to work. [0003] Industrial robot (Industrial robot) is an automatic control, reprogrammable, multi-functional, multi-degree-of-freedom operation and is used to carry materials, workpieces or manipulate tools to complete various operations. It can be fixed or mobile. The control function, structural characteristics and autonomy of industrial robots are different, but they must meet three basic requirements: use CPU as the core controller for control, such as industrial control computer...

AI Technical Summary

Problems solved by technology

[0008] Most of the traditional robot arms are fixed in shape and type, that is, they are specially designed according to the requirements of users, and can only be applied to a specific environment. If the application scene is changed, the original robot arm will no longer be applicable. In addition, Traditional manipulators have poor flexibility, and there are many specifications of various manipulators, the versatility of parts is poor, and there are problems such as unstable quality and reliability, which cannot meet actual needs
