Description

Technical Field

[0001] The present application relates to the technical field of welding fixtures, and more specifically, to an auxiliary fixture for a welding machine. Background Art

[0002] A welding machine is a device used to weld metal materials. When welding different parts, the welding machine needs to use auxiliary clamps to stabilize the welding between parts and improve efficiency and welding quality.

[0003] In the related technology, the semicircular plate is driven by an electric slide to move and clamp the pipe. For example, the patent with the prior art publication number CN219188950U provides a pipe welding auxiliary clamp. The device is provided with a first electric slide and a semicircular plate. Two pipes are placed in a limiting cylinder, and then the two second electric slides move toward the middle, so that the two translation plates move toward the middle. When the two pipes are docked, the second electric slide stops moving, and then the multiple first electric slides move, so that the semicircular plate moves toward the middle, so that the two semicircular plates are against the side walls of the pipe.

[0004] Although the above-mentioned prior art solution can achieve the effect of clamping the pipe through the first electric slide rail semicircular plate, it still has the following defects: the diameter of the semicircular plate is not adjustable, and it can only clamp pipes of a single diameter, which has poor practicality.

[0005] In view of this, we propose an auxiliary fixture for a welding machine. Utility Model Content
