Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, specifically to a cooler spot welding positioning tooling and fixture. Background Technology

[0002] In the electric welding process of coolers, tooling fixtures are required to clamp and fix the cooler before welding the inlet and outlet connectors and the support. Existing tooling fixtures typically use bolts to fix the cooler, which requires multiple adjustments and tightenings. This makes it difficult to quickly and accurately position and fix the inlet and outlet connectors and the support to the tube shell. The clamping process is time-consuming, affecting processing efficiency, especially in mass production. In addition, after fixing the cooler, the existing fixtures usually cannot adjust their angle, making some welding points difficult to reach. Workers need to frequently adjust their welding posture, which not only increases labor intensity but also reduces welding quality and efficiency. Therefore, there is an urgent need to design a new type of cooler welding tooling fixture to solve the problems of complex clamping operation and inconvenient angle adjustment in the existing technology, thereby improving welding efficiency, reducing worker labor intensity, and adapting to diverse processing needs.
