Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0026] The embodiment of the present application provides a stud welding quality inspection tool, which can solve the problem of the inconvenience in inspecting the welding quality of stud welding in the related art.

[0028] In actual use, since the detection tool body 1 is provided with a through hole 2 for passing the stud along the height direction, after the stud welding operation is completed, the through hole 2 of the detection tool body 1 can be sleeved on the stud, and then the detection tool body 1 is shaken. If the shaking of the detection tool body 1 drives the stud to shake, causing the stud to separate and fall off from the welded parent material, it can be judged that the stud welding quality does not meet the standard; if the detection tool body 1 is shaken to drive the stud to shake, the stud and the welded parent material are well connected, it can be judged that the stud welding quality is qualified. The detection tool of the present application can judge the quality of stud welding by directly sleeved on the stud, is easy to operate, convenient for daily use, and can improve detection efficiency. At the same time, a resistance component 4 is rotatably connected to the side wall of the detection tool body 1. The resistance component 4 is used to extend into the through hole 2 to resist and fix the stud, so as to facilitate shaking the detection tool body 1 to detect the stud; when the through hole 2 of the detection tool body 1 is sleeved outside the stud, the resistance component 4 can be used to resist and fix the stud. Specifically, by adjusting the distance that the resistance component 4 penetrates into the through hole 2, the detection tool body 1 can be adapted to the resistance and fixation of studs of different diameters, thereby improving the universal applicability of the detection tool body 1 for detecting studs of different diameters, facilitating detection, and improving detection efficiency.

[0029] In some optional embodiments, such as Figure 1 and Figure 2 As shown, the interference assembly 4 includes an adjusting bolt 41 threadedly connected to the side wall of the detection tool body 1. The interference assembly 4 also includes an arc-shaped interference piece 42 fixed to one end of the adjusting bolt 41.

[0030] The abutment assembly 4 includes an adjusting bolt 41 and an arc-shaped abutment piece 42 fixed to one end of the adjusting bolt 41. The adjusting bolt 41 is rotatably connected through the threaded structure of the side wall of the detection tool body 1. In actual use, the diameter of the through hole 2 of the detection tool body 1 can be set larger. When the diameter of the stud to be detected is smaller than the diameter of the through hole 2 of the detection tool body 1, the adjusting bolt 41 can be rotated so that the adjusting bolt 41 moves toward the direction close to the through hole 2, and the stud can be fixed by the abutment assembly 4. The stud fixed by abutment can be fixed with the detection tool body 1 to form a whole, so that the welding quality of the stud can be judged by directly shaking the detection tool body 1, thereby improving the reliability and convenience of the detection.

[0031] At the same time, an arc-shaped abutment 42 is fixedly arranged at one end of the adjusting bolt 41. In actual use, two abutment assemblies 4 can be arranged relatively, that is, after the studs of different diameters are adaptively adjusted by the adjusting bolt 41, the two arc-shaped abutment 42 arranged relatively can clamp the abutment studs and fix the studs, so as to facilitate the inspection of the stud welding quality.

[0032] In some optional embodiments, a rubber gasket is fixedly provided on the outer wall of the arc-shaped resistance member 42. The provision of the rubber gasket can increase the friction between the arc-shaped resistance member 42 and the stud, thereby ensuring the reliability of the arc-shaped resistance member 42 in resisting and fixing the stud. The provision of the rubber gasket, a flexible material, can prevent the thread of the stud from being damaged when the stud is resisted and fixed.

[0033] In some optional embodiments, such as Figure 1 and Figure 3 As shown, the detection tool body 1 includes an extension section 3 arranged at the bottom of the detection tool body 1 and extending to opposite sides. The setting of the extension section 3 can position the detection tool body 1 in the shaking direction, and can enhance the stability of the structure, prevent the feeling of instability when shaking the detection tool body 1, and facilitate detection. The bottom of the extension section 3 is provided with an arc chamfer to prevent scratches on the base material when shaking the detection tool body 1.

[0034] In some optional embodiments, the detection tool body 1 includes a gripping section 11 and a sleeve section 12 detachably connected to the gripping section 11, and the through hole 2 is provided in the sleeve section 12. The gripping section 11 and the sleeve section 12 are arranged in a separate form, so that after the sleeve section 12 is used multiple times and is worn, the sleeve section 12 can be directly replaced without directly replacing all the detection tools. This partial replacement method can save costs. A clamping block is provided on the side of the sleeve section 12 close to the gripping section 11, and a slot matching the clamping block is provided on the side of the gripping section 11 close to the sleeve section 12. The provision of the clamping block and the slot facilitates the connection and disassembly of the gripping section 11 and the sleeve section 12. In actual use, a screw structure can also be provided on the sleeve section 12, and a threaded hole matching the screw structure can be provided on the gripping section 11, so as to fix and disassemble the sleeve section 12 and the gripping section 11.

[0035] In some optional embodiments, an arc chamfer is provided at the bottom edge of the through hole 2 to prevent the stud from being scratched during the process of sleeve connection. In actual use, an arc groove is provided on the side wall of the detection tool body 1 for easy gripping. The provision of the arc groove makes it convenient for construction workers to grip and operate.

The detection tool of the present application can judge the quality of stud welding by directly sleeved on the stud, which is easy to operate, convenient for daily use, and can improve the detection efficiency. At the same time, a resistance component 4 is rotatably connected to the side wall of the detection tool body 1. The resistance component 4 is used to extend into the through hole 2 to resist and fix the stud, so as to facilitate shaking the detection tool body 1 to detect the stud; when the through hole 2 of the detection tool body 1 is sleeved outside the stud, the resistance component 4 can be used to resist and fix the stud. Specifically, by adjusting the distance that the resistance component 4 penetrates into the through hole 2, the detection tool body 1 can be adapted to the resistance and fixation of studs of different diameters, thereby improving the universal applicability of the detection tool body 1 for detecting studs of different diameters, facilitating detection, and improving detection efficiency.
