Description

Technical Field

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

[0002] Auto parts processing refers to the various units that constitute the overall auto parts processing and the products that serve the auto parts processing. As the foundation of the automotive industry, auto parts are a necessary factor to support the sustainable and healthy development of the automotive industry. In particular, the current independent development and innovation carried out by the automotive industry requires a powerful parts system to support it. Patent No. CN202122854396.4 discloses a welding fixture for welding auto parts, which can clamp welding round tubes of different diameters to avoid the welding fixture being able to clamp only round tubes of a single diameter, thus narrowing the scope of application of the fixture. However, since auto parts not only have round tube structures, but also some plate-shaped or flat workpieces, and the welding fixture can only clamp round tube-shaped workpieces, its functionality is relatively single, its limitations are strong, and it is not convenient to use. To this end, we propose a welding fixture for welding auto parts. Utility Model Content

The operation of the servo motor is convenient to drive the worm to rotate under the operation of the reducer, so that the worm can mesh with the worm wheel that can rotate on the top of the cushion seat and drive it to rotate. At the same time, the hole on the inner circumference of the worm wheel is convenient to be screwed with the lead screw, and then the worm wheel is convenient to be screwed with the lead screw and drive the upper clamping plate to move, so that the upper clamping plate can step along the two sets of lead screws and approach the lower clamping plate, so that the upper clamping plate and the lower clamping plate are close to each other and the automobile parts are clamped and limited, which is convenient for subsequent welding.

[0008] Specifically, the top surface of the table top is equipped with vertical rods that are matched and connected with the upper clamping plate, and there are multiple groups of vertical rods.
