High-precision cantilever type six-axis welding robot

Abstract

The invention discloses a high-precision cantilever type six-axis welding robot which comprises a linear motion device, a Y-axis rotating device, a large arm rotating device, a small arm rotating device, a wrist rotating device and a finger rotating device. The Y-axis rotating device is arranged on the linear motion device, the large arm rotating device is arranged on the Y-axis rotating device, the small arm rotating device is arranged on the large arm rotating device, the wrist rotating device is arranged on the small arm rotating device, and the finger rotating device is arranged on the wrist rotating device. The invention belongs to the technical field of industrial robots, and particularly relates to the high-precision cantilever type six-axis welding robot. According to the high-precision cantilever type six-axis welding robot, bionic design is adopted, the structure of a human body is restored and simulated, and the problems that a six-axis robot in the current market is complex in structure and waste of degree of freedom exists are effectively solved through mutual linkage cooperation of all movable parts.

Description

technical field [0001] The invention belongs to the technical field of industrial robots, and specifically refers to a high-precision cantilever type six-axis welding robot. Background technique [0002] In recent years, my country's manufacturing industry has developed rapidly. More and more companies use industrial robots to replace the original manual operations, which improves the consistency and pass rate of production. This is especially true in the welding field. The welding work requires operators to have skilled experience and Skills require high personal quality, and it is even more difficult to ensure the consistency of welding. Therefore, the field of welding is one of the earliest fields in my country to popularize automated production lines. [0003] The current welding robots are mostly four-axis welding robots or six-axis welding robots. The traditional six-axis welding robots are all cantilever structures, and the base is fixed. There is a waste of degrees of...

Problems solved by technology

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a high-precision cantilever type six-axis welding robot, which adopts bionic design, restores the structure of the simulated human body, and simulates the leg walking through the linear motion device to realize the adjustment of the base position. Move, expand the working range of the welding robot, simulate the in-situ rotation angle through the Y-axis rotation device, simulate the rotation of the human body's large arm and small arm through the large arm rotation device and the small arm rotation device, adjust the height of the working position, and adjust the height of the working position through the wrist The rotation device simulates the rotation of the wrist of the human body, and rotates with the fingers. The finger joints are simulated by the finger rotation device to achieve fine position movement, which effectively solves the problem of complex structure and waste of degrees of freedom in the current six-axis robot on the market.
