Embodiment Construction

[0024] In order to solve the technical problem that the existing automatic welding machine has a low degree of automation, which will lead to low welding quality, the embodiment of the present invention provides a welding robot. The general idea is as follows:

[0025] The execution terminal of the small multi-axis open chain welding robot provides a larger working range and spatial accessibility for all-position welding of pipelines. The posture of the welding torch is automatically adjusted in real time according to the change of the welding position, thereby improving the performance of all-position welding of pipelines The degree of automation and intelligence improves the quality of welding forming.

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in ...

Abstract

The invention discloses a welding robot used for solving the technical problem that the automatic welder in the prior art is low in automation level further leading to low welding forming quality. The welding robot comprises a heeling drive arm, a rotary drive mechanism, an angle oscillating drive arm, a lifting drive arm and a welding mechanism. The rear end of the rotary drive mechanism is in first connection with the tilting drive arm and capable of rotating on the first vertical plane; the front end of the rotary drive mechanism is in second connection with the rear end of the angle oscillating drive arm and capable of rotating on the horizontal plane; the front end of the angle oscillating drive arm is in third connection with the rear end of the lifting drive arm and capable of rotating on the second vertical plane; the welding mechanism is mounted to the front end of the lifting drive arm. Automation and intelligent level of all-position welding of pipelines is heightened greatly, and further welding forming quality can be improved.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, in particular to a welding robot. Background technique [0002] The welding of long-distance oil and gas pipelines needs to be welded by automatic welding machines; [0003] The current automatic welding machines all adopt the transmission configuration of two linear motion axes, that is, a welding torch yaw linear axis plus a welding torch vertical linear axis. Because the pipeline welding is all-position welding, the welding torch posture needs to be adjusted dynamically at each phase of the pipeline. The existing two linear axis technical solutions provide less degrees of freedom and a small range of accessibility, so there are only two types of lateral swings: triangle and rectangle. The form cannot fully meet the adjustment requirements of welding torch attitude with multiple degrees of freedom. [0004] Therefore, the degree of automation of existing automatic welding machines is not h...
