Problems solved by technology

[0005] The purpose of the present invention is to overcome the problem that in the prior art, the existing mechanical arm can only perform single-angle welding, and it takes a lot of time to weld complex structures that require multi-angle welding, which reduces welding efficiency and poor versatility. The problem that the welding quality of difficult positions cannot be guaranteed, provides a multi-degree-of-freedom mechanical arm for automatic welding with simple structure, low technical threshold, easy operation and use, which can realize multi-angle welding and improve welding efficiency.

Abstract

The invention belongs to the technical field of automatic welding and mechanical arm design, and particularly relates to a multi-degree-of-freedom mechanical arm for automatic welding. The multi-degree-of-freedom mechanical arm comprises a base, a vertical rotating shaft arranged on the base, a rotating base arranged on the vertical rotating shaft, a horizontal rotating shaft arranged on the rotating base, a rotating arm arranged on the horizontal rotating shaft, a connecting rotating ball arranged at the tail end of the rotating arm and a welding gun arranged on the connecting rotating ball,wherein the base is connected with the rotating base through the vertical rotating shaft; the welding gun is connected with the rotating arm through the connecting rotating ball; and the connecting rotating ball is used for realizing multi-degree-of-freedom rotation of the welding gun. The multi-degree-of-freedom mechanical arm has the characteristics of simple structure, low technical threshold,easiness in operation and use, capability of randomly rotating the welding gun and realizing multi-angle welding and improvement of the welding efficiency.

Description

technical field [0001] The invention belongs to the technical field of automatic welding and mechanical arm design, in particular to a multi-degree-of-freedom mechanical arm for automatic welding. Background technique [0002] Because welding has the characteristics of good sealing, high connection strength, strong adaptability and high production efficiency, it is widely used in the connection of large equipment and structural parts such as pressure vessels. Therefore, the quality of welding often determines the service life and safety of a part. The development of welding technology has gone through the development process from arc welding, oxygen gas welding, resistance welding, to submerged arc welding, gas metal arc welding, flux cored arc welding, and then to laser and electron beam welding; in this process, research Researchers continue to explore the improvement of welding technology, from manpower to automation. Nowadays, in welding technology, people usually use ...
