Welding robot and device for adjusting posture of welding gun of welding robot

Abstract

The invention discloses a device for adjusting the posture of a welding gun, which is used for a welding robot. The device comprises a first guide device arranged on the welding robot and a first driving device arranged on the upper part of the welding gun (0), wherein the first driving device drives the upper part of the welding gun (0) to sway along the first guide device, and the guiding center of the first guide device coincides with the endpoint at the tail end of the welding gun (0). In the working process of the welding gun, the first driving device drives the upper part of the welding gun (0) to sway along the first guide device, and because the guiding center of the first guide device coincides with the endpoint at the tail end of the welding gun (0), when the upper part of the welding gun (0) sways along the fist guide device, the position of the endpoint at the tail end of the welding gun (0) is not changed, and the posture of the welding gun (0) in the welding process is changed, so the welding stability and the welding seam quality can be stably ensured for a long time.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a welding torch posture adjustment device for a welding robot. The present invention also relates to a welding robot comprising the above welding torch attitude adjustment device. Background technique [0002] With the rapid development of my country's economic construction, welding technology is more and more widely used in various fields of engineering construction due to its advantages of reliable connection and low cost. [0003] For a long period of time, manual welding is generally used in welding construction in my country. The labor intensity of workers is high, and the welding quality and welding efficiency are low, which cannot meet the actual production requirements for welding technology. [0004] In order to reduce the labor intensity of workers and improve welding quality and welding efficiency, various welding equipment have emerged, especially the devel...

Problems solved by technology

In the welding process, for example, when the welding current is large, there will be more metal in the molten pool. At this time, when the welding torch performs downhill welding, the walking direction of the welding torch is the same as the flow direction of the molten pool metal, which will cause serious When the welding torch performs uphill welding, the walking direction of the welding torch is opposite to the flow direction of the molten pool metal, which will form a more serious countercurrent welding phenomenon.

It is well known that the phenomena of downstream welding and countercurrent welding during the welding process will lead to lower stability of the welding process and lead to poor welding quality
