Six-axis robot

Abstract

The invention discloses a six-axis robot. The six-axis robot comprises a main control center, a base, a first axis mechanical arm, a second axis mechanical arm connected with the first axis mechanicalarm, a third axis mechanical arm connected with the second axis mechanical arm, a fourth axis mechanical arm connected with the third axis mechanical arm, a fifth axis mechanical arm connected with the fourth axis mechanical arm and a sixth axis mechanical arm connected with the fifth axis mechanical arm, wherein the first axis mechanical arm, the second axis mechanical arm, the third axis mechanical arm, the fourth axis mechanical arm, the fifth axis mechanical arm and the sixth axis mechanical arm are sequentially installed on the base. The fourth axis mechanical arm comprises a motor A anda connecting plate A arranged on the motor A. The right side of the connecting plate A is provided with a pair of parallel arms A. A connecting column is arranged between the parallel arms A. The fifth axis mechanical arm comprises a motor B and a U-shaped arm. One head of the U-shaped arm is fixedly connected with the parallel arms A. The motor B is provided with a drive shaft. The six-axis robot is simple in structure and convenient to operate, the manufacturing cost is reduced, by the adoption of the structure, the stability between the fourth axis mechanical arm, the fifth axis mechanicalarm and the sixth axis mechanical arm can be improved, connecting is more compact, and use for an operator is facilitated.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a six-axis robot. Background technique [0002] The six-axis robot has six-axis mechanical arms, similar to human arms, and is mainly used for loading, unloading, painting, surface treatment, testing, arc welding, spot welding, packaging, assembly, cutting machine tools, fixing, special assembly operations, Forging, casting, etc., its advantages: it has a high degree of freedom, has a six-axis mechanical arm suitable for almost any trajectory or angle of work, can be freely programmed, complete fully automatic work, can provide production efficiency, and controllable errors It can replace many complex tasks that are not suitable for manpower and harmful to health, such as spot welding of automobile shells, so it is widely used. However, the fourth of the six-axis mechanical arms in the existing six-axis robot 1. The connection relationship between the fifth and sixth axis mecha...

AI Technical Summary

Problems solved by technology

[0003] In view of the deficiencies in the background technology, the present invention provides a six-axis robot, the purpose of which is to solve the problem of the fourth, fifth and sixth axis mechanical arms among the six-axis mechanical arms in the six-axis robot in the prior art. The connection relationship between them is not compact enough, the stability performance is poor, and the manufacturing process and stability requirements of the first, second and third axis mechanical arms are high, which leads to the problem of high production cost
