[0026] It is worth noting that the specific structure, connection method, and working principle of the aperture detection unit 3 are all based on the utility model disclosed in the authorization announcement number "CN222560917U" as "an aircraft parts aperture detection mechanism", and are not the main technical problems to be solved in this utility model, so they will not be described in detail. At the same time, the bidirectional screw drive unit 5 is used to drive two sets of symmetrically arranged limiting components 42 to move towards each other or away from each other, and the conveyor belt unit 2 is used to transport the automotive parts with the aperture to be detected. The specific structure and working principle of the bidirectional screw drive unit 5 and the conveyor belt unit 2 are existing technologies that have been disclosed in the market, and are not the main technical problems to be solved in this utility model, so they will not be described in detail in this utility model.

[0027] A connecting plate 43 is fixedly installed at both ends between the two first fixing frames 41, and auxiliary guide components are provided on adjacent surfaces of the connecting plate 43. One side of the auxiliary guide component is connected to the limiting component 42.

[0028] Meanwhile, a second fixing frame 45 is provided on the top of the workbench 1 outside the conveyor belt unit 2 and on the side of the first fixing frame 41. A sliding groove is provided in the second fixing frame 45, and two limiting sliders are slidably arranged in the sliding groove. The two limiting sliders are respectively connected to the adjacent limiting components 42.

[0029] Meanwhile, the limiting component 42 includes a fixed frame and a guide frame. The guide frame is connected to one side of the fixed frame, and both the fixed frame and the guide frame have grooves on the side closest to the middle of the conveyor belt unit 2.

[0030] Furthermore, multiple fixed shafts 421 are installed at equal intervals in the groove, and guide rollers 422 are sleeved on the outer wall of the fixed shafts 421.

[0031] Furthermore, the auxiliary guide assembly includes a fixed rod 44, and a movable rod 442 is slidably disposed inside the fixed rod 44. The movable rod 442 is T-shaped, and one end of the movable rod 442 extends out of the fixed rod 44 and connects to the limiting assembly 42.
