Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically to a welding fixture for automotive steering columns. Background Technology

[0002] The steering column is a crucial component in automobiles, serving as the element connecting the steering wheel and steering gear in the steering system. Its primary function is to transmit torque. During the manufacturing process of the steering column, the column body is typically welded to other components to meet usage requirements. Therefore, automated laser welding equipment for automotive steering columns is required for this welding process.

[0003] A search revealed that patent document CN215091367U discloses an automated laser welding device for automotive steering columns, comprising a fixed column, a worktable, and a base. The worktable is fixedly mounted on the top of the base, and a fixed seat is fixedly mounted on the top of the worktable. A servo motor is fixedly mounted on one side of the fixed seat, and a turntable extending from the fixed seat is fixedly mounted on the output end of the servo motor. A clamp is movably mounted on one side of the turntable, and a guide roller is movably mounted on the front end of the clamp. A sliding frame is slidably mounted on the worktable on one side of the fixed seat, and a limiting frame corresponding to the clamp is movably mounted on one side of the sliding frame. A fixed column is fixedly mounted on the base at the rear end of the worktable, and a sliding block is slidably mounted on the fixed column.

The column 3 is fixed to the base 1, and the slide 5 can slide on the column 3, driven by the first electric telescopic rod 4, thereby realizing the vertical movement of the welding gun 2.

[0026] A clamping mechanism for fixing the car steering column is provided on the base 1. The base 1 has a sliding groove 11 and a mounting groove 18. The clamping mechanism includes two mounting seats 7 disposed on the upper surface of the base 1, and a clamp 8 is rotatably mounted between the two mounting seats 7. A first drive motor 9 is fixed to the outer surface of the left mounting seat 7, and the output shaft of the first drive motor 9 is fixed to the outer surface of the left clamp 8. A second electric telescopic rod 10 is fixed to the upper surface of the base 1. Specifically, a slide block 71 that is slidably connected to the sliding groove 11 is fixed to the lower surface of the left mounting seat 7, the right mounting seat 7 is fixed to the upper surface of the base 1 by bolts, and the output end of the second electric telescopic rod 10 is fixed to the outer surface of the left mounting seat 7.

[0027] To protect the slide 11, a shielding cloth 12 is provided inside the mounting groove 18 to cover the slide 11.
