Automatically tracking device of welded joint machinery

Abstract

The invention discloses an automatically tracking device of welded joint machinery. The automatically tracking device comprises a guide wheel mechanism which is provided with a guide wheel capable of rotating freely; an upper and lower adjustment mechanism which is provided with a first linear bearing extending along the vertical direction and an upper elastic body and a lower elastic body which are arranged separately at the upper side and the lower side of the first linear beating; a left and right adjustment mechanism which is provided with a second linear bearing extending along the left and right direction and a left elastic body and a right elastic body which are arranged separately at the left side and the right side of the second linear bearing; a fine adjustment mechanism which is fixedly connected with the guide wheel mechanism and drives the guide wheel to keep close contact with both one side and the top part of a weld groove; and a welding gun fixing mechanism which is matched with the guide wheel mechanism, is correspondingly connected with the first linear bearing or the second linear bearing, and is fixedly provided with a welding gun at the end part. The left and right adjustment mechanism is connected with the upper and lower adjustment mechanism, and the guide wheel mechanism is connected with the first linear bearing or the second linear bearing. The automatically tracking device can automatically adapt to shift of the left and right, the upper and lower positions of a welded joint, so as to automatically track the welded joint.

Description

technical field [0001] The invention relates to the technical field of welding automation, and more specifically relates to a mechanical automatic tracking device for welding seams, which is a mechanical device for automatically tracking circular welding seams. Background technique [0002] With the rapid development of modern industrial technology, automatic welding technology has been widely used in various fields. In the traditional field of circular seam welding, special machines are generally used for welding. [0003] Among them, when welding the end of the circular workpiece and the flat plate, the workpiece must be tilted at a certain angle first, but because the shape of the cylindrical welding workpiece itself and the consistency of the groove usually have deviations, the workpiece is rotated for welding. When the weld bead and the welding torch are in the relative position, the relative position will deviate, resulting in defects such as missing welding and underc...
