Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to an automatic detection device for a stainless steel pipe weld. Background Art

[0002] The stainless steel pipe weld inspection device mainly focuses on the accurate, efficient and reliable inspection of weld quality. As the key part of stainless steel pipe connection, the weld quality directly affects the safety and stability of the entire pipeline system.

[0003] The existing stainless steel pipe welds are mainly inspected manually, which has a series of significant shortcomings and limitations. First, the stainless steel pipe needs to be turned over during manual inspection. Manual turning over of the stainless steel pipe not only increases the labor intensity of the operator, but also may lead to safety risks during the operation, especially when handling heavy or large-sized stainless steel pipes. The operator needs to pay more physical strength and energy, which not only reduces work efficiency, but also may pose a potential threat to the operator's health. Secondly, the manual inspection process is relatively cumbersome and time-consuming. The operator needs to turn over and check the welds one by one, and judge by naked eyes or simple tools. This is not only inefficient, but also difficult to meet the efficient production needs on large-scale production lines. To this end, we provide an automatic inspection device for stainless steel pipe welds. Utility Model Content

[0004] The utility model aims to provide a stainless steel pipe weld automatic detection device to solve the problems raised in the above background technology.

[0016] One end of the stainless steel tube is opposite to the three-jaw wedge screw chuck. Then, by rotating the handle provided on the three-jaw wedge screw chuck, the wedge screw is engaged with the nut, thereby driving the jaw body to move inward or outward to adapt to stainless steel tubes of different diameters. When the jaw body fits tightly against the outer wall of the stainless steel tube, the clamping is completed.
