AI Technical Summary

⚠Technical Problem

Existing technologies, such as single-channel positioning fixtures, result in low production efficiency. Multi-claw integrated clamping jaws are difficult to guarantee flatness and are costly. Insufficient magnetic force leads to poor welding or warping of small hardware, which cannot meet the production requirements of high-end smart dial welding.

⚗Method used

The quick-change spot welding fixture is adopted, and the frame is driven to rotate by a swing cylinder to achieve continuous welding. Combined with elastic sliding moving pressure claws and fixed pressure claws, it ensures that small hardware does not warp during high-temperature spot welding. Rotary cylinders and suction cups are used for precise positioning and clamping.

🎯Benefits of technology

It enables rapid product switching and continuous welding, improves production efficiency, reduces wear and operating costs of the pressure claws, and ensures welding quality and precision.

Abstract

This utility model discloses a quick-change spot welding fixture, belonging to the field of welding fixture technology. A quick-change spot welding fixture includes a base; a frame rotatably mounted on the base, with at least two sets of product positioning plates fixedly mounted on the frame. Each product positioning plate has a clamping part for holding workpieces, and the base has a driving part for driving the frame to rotate; a fixed seat mounted on the product positioning plate, with fixed clamping claws for holding accessories fixedly mounted on the fixed seat, and multiple sets of movable clamping claws corresponding to the fixed clamping claws sliding elastically on the fixed seat. This utility model achieves rapid product switching for spot welding of small hardware on the side of a flat plate by rotating the frame and two sets of product positioning plates via the driving part, thus improving production efficiency. By using elastically sliding movable clamping claws, the drawback of substandard flatness of multiple clamping claws is avoided, while ensuring the accuracy of the clamping claws and sufficient elasticity to clamp the small hardware.
