Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a welding fixture. Background Art

[0002] Automobiles are assembled from various parts. During the production and processing of automobile parts, some parts need to be welded. During welding, the parts need to be fixed with fixtures. Fixtures refer to a process equipment for clamping workpieces. They are widely used in the process of cutting, heat treatment, assembly, welding and testing in the mechanical manufacturing process. In order to improve the processing efficiency of automobile parts, a welding fixture is needed. However, the existing welding fixtures still have the following shortcomings:

[0003] For example, the utility model with application number 202320691528.2 discloses a fixture for welding automobile parts. The utility model realizes the effect of rotating the parts under the clamping of the fixture through the bearings and rotating shafts arranged in the disc, so that after welding one side of the part, the worker does not need to move to the other side of the part to weld the part, thereby reducing the worker's movement frequency and solving the problem of welding work efficiency caused by the inability of the fixture to rotate the part. However, similar to the comparative documents of the above-mentioned application, when the existing welding fixtures are used, most of the welding fixtures are prone to position displacement in the process of limiting the automobile parts, which makes the welding of parts prone to errors, thereby affecting the subsequent processing yield of automobile parts, resulting in reduced practicality of the welding fixtures and reduced use efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a welding fixture is proposed. Utility Model Content
