[0002] In the automotive production and manufacturing industry, in order to ensure product quality, before the welding and assembly of each automotive component, the welding parts need to be subjected to quality inspection. During the inspection, to ensure accurate and convenient inspection, some larger welding parts with cavities must be fixed with jigs to facilitate comprehensive inspection.

[0003] The existing patent CN221088784U discloses a fixed clamping structure, including a workbench, a support plate, a first motor, a bidirectional screw, a base, a winding box, and two groups of clamping components. The support plate is located below the first motor, the first motor is located outside the workbench, the other end of the bidirectional screw is rotatably connected to the workbench and is located inside the workbench, and the surface of the bidirectional screw has a bidirectional thread. The base is located above the workbench, the winding box is located above the base, the two groups of clamping components are symmetrically arranged, and each group of clamping components includes a moving block, a balance plate, a fixing member, and a protective member. The moving block is threadedly connected to the bidirectional screw and is located inside the workbench, and the bidirectional screw penetrates through the moving block. The balance plate is located above the moving block, the fixing member is located above the balance plate, and the protective member is rotatably connected to the winding box and is located on both sides of the winding box, so as to adjust the distance between the two clamping devices according to the size of different parts.

[0004] Based on the retrieval of the above patent and the discovery of the fixed clamping structure in the prior art, when the above clamping structure is used, through the operation of the first motor, the bidirectional screw rotates to control the movement of the two balance plates, so as to adjust the distance between the two bearing plates, facilitating the clamping and fixing of parts. However, in actual use, to ensure the quality of parts, different positions of the parts need to be inspected. For the above structure, once the parts are fixed and need to be flipped and adjusted, it is relatively troublesome. The position of the bearing plate is fixed, and the parts cannot be rotated flexibly, which is not convenient for comprehensive and rapid inspection, resulting in reduced practicability.
