Description

Technical Field

[0001] The utility model relates to a welding device, in particular to a welding device used for basket metal bars, belonging to the technical field of basket welding. Background Art

[0002] Wire baskets are widely used in life. They are usually made by welding wires and metal bars. When welding wire baskets, the wires and metal bars must first be positioned and fixed according to the shape of the wire basket, and then the contact points are welded.

[0003] A welding device for welding a plastic-dipped basket is disclosed in Chinese patent application publication CN218363117U. The device places the basket on a rotating seat and drives the clamping plates to move through a threaded rod so that the four clamping plates clamp the lower end of the basket. The basket is protected by elastic protrusions to improve its practicality. The welding gun is fixed to an electric telescopic rod through a fixing part, and the welding gun is moved back and forth through the electric telescopic rod. The electric telescopic rod slides in an electric slide rail on a support frame through a slider to move it up and down. The basket can be welded at different heights, thereby improving its welding efficiency.

[0004] Although the solution of the above patent can clamp the lower end of the basket by means of a clamping plate, manually rotating the threaded rod can easily cause the clamping plate to apply excessive clamping force to the basket. If this force exceeds the yield strength of the basket material, the metal portion of the basket will deform, affecting its structural integrity and function. In addition, the device can only move the welding gun up and down, making it difficult to weld the left and right parts of the basket, and has low flexibility. Utility Model Content

The output end of the first rotating motor is fixed with a threaded rod, and one end of the threaded rod is rotatably connected to the inner side wall of the chute. A threaded block is threadedly connected to the outer surface of the threaded rod, and the outer surface of the threaded block is slidably connected to the inner wall of the chute.
