Description

Technical Field

[0001] The utility model relates to the technical field of machinery, and particularly relates to a tooling for resistance spot welding tear inspection. Background Art

[0002] In the production process of resistance spot welding, tear inspection is a key quality control step. In the prior art, usually after the resistance spot welding is completed, two test plates are clamped and a tearing force is applied to check the diameter of the weld spot. This inspection process is to ensure that the strength and quality of the weld spot meet the standards. However, the existing operation methods have obvious deficiencies. In actual production, a bench vice is usually used to clamp one side and a vice is used to clamp the other side for tearing. However, this operation is particularly difficult when dealing with thicker plates and larger weld spots, the process is cumbersome and time-consuming, resulting in a reduction in production efficiency. Especially in high-volume production lines, this manual operation not only increases the labor intensity but also affects the production progress and inspection consistency.

[0003] In summary, there is an urgent need for a tooling for resistance spot welding tear inspection, which is convenient to operate, saves manpower and improves efficiency. Summary of the Utility Model
