Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0030] By providing a fixture for inspecting an automotive crossbeam welding assembly in an embodiment of the present application, the problem that the position of the rod-shaped detecting member on the inspection table is fixed and the overall size of the rod-shaped detecting member is fixed is solved. When facing mounting holes of different sizes at different automotive crossbeams, the rod-shaped detecting member cannot be accurately fitted with the inner wall of the mounting hole, and the detection limitation of the fixture is relatively large. The transformation of the detection diameter of the rod-shaped detecting member and the transformation and installation of the rod-shaped detecting member at any position on the inspection table are realized.

[0031] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0032] An embodiment of the utility model discloses a fixture for inspecting an automotive crossbeam welding assembly.

[0033] According to the attached Figure 1-7 As shown, it includes an inspection table 1 and a detecting member 2 arranged on the top of the inspection table 1 for inspecting the automotive crossbeam welding assembly. Referring to the attached Figure 1 , place the automotive crossbeam on the inspection table 1, and insert the detecting member 2 into the mounting hole opened at the crossbeam. The mounting hole is not specifically shown in the attached drawings, so that the opening size of the mounting hole can be detected through the detecting member 2.

[0034] Referring to the attached Figure 3 , attached Figure 6 and attached Figure 7 , a transformation mechanism is arranged on the top of the inspection table 1. Through the arranged transformation mechanism, the overall diameter of the detecting member 2 is changed to adapt to the accurate detection of mounting holes with different hole diameters at the crossbeam. The transformation mechanism includes a mounting seat 3. The mounting seat 3 is snap-connected to the top of the inspection table 1. A plurality of mounting cavities 37 for mounting the mounting seat 3 are opened on the top of the inspection table 1, so that the detecting member 2 can be installed in the mounting cavities 37 at different positions through the mounting seat 3 according to the mounting holes opened at different positions of the crossbeam, realizing the flexible transformation of the position of the detecting member 2 on the inspection table 1. A moving base 31 for supporting the detecting member 2 is slidably arranged inside the mounting seat 3. A positioning plate 21 is arranged on the outer wall of the detecting member 2. Referring to the attached Figure 6, the detection piece 2 is composed of four groups of arc-shaped plates. A set of positioning plates 21 are arranged on the outer walls of the four groups of arc-shaped plates. The positioning plates 21 can position the connection position between the cross beam and the detection piece 2. The fixing frame 33 is arranged on the top of the moving base 31. The adjusting screw rod 34 and the threaded block 35 are respectively connected to the fixing frame 33 and the support plate 36. The adjusting screw rod 34 is rotatably arranged inside the fixing frame 33. One end of the adjusting screw rod 34 extending to the upper part of the fixing frame 33 is provided with a bolt. One end of the support plate 36 is hinged to the inner surface of the detection piece 2. The support angle of the support plate 36 is adjusted through the threaded connection between the adjusting screw rod 34 and the threaded block 35. One end of the support plate 36 away from the detection piece 2 is hinged to the outer wall of the threaded block 35. A limit telescopic rod 38 is arranged between the inner surface of the detection piece 2 and the outer wall of the fixing frame 33. By rotating the adjusting screw rod 34, under the action of the threaded connection between the adjusting screw rod 34 and the threaded block 35, the threaded block 35 moves upward or downward along the outer wall of the adjusting screw rod 34. When the threaded block 35 moves downward along the outer wall of the adjusting screw rod 34, the opening angle of the support plate 36 hinged between the threaded block 35 and the detection piece 2 gradually increases, so that the detection piece 2 moves away from the fixing frame 33, making the overall diameter of the detection piece 2 increase after adjustment. When the threaded block 35 moves upward along the outer wall of the adjusting screw rod 34, the opening angle of the support plate 36 hinged between the threaded block 35 and the detection piece 2 gradually decreases, so that the detection piece 2 moves closer to the fixing frame 33, making the overall diameter of the detection piece 2 smaller after adjustment.

[0035] Refer to the appendix Figure 5 , an electric telescopic rod 32 is arranged inside the mounting seat 3. One end of the electric telescopic rod 32 is connected to one side of the moving base 31. By arranging the electric telescopic rod 32, the position of the detection piece 2 at the mounting seat 3 can be adjusted to ensure that the detection piece 2 can be accurately inserted into the mounting hole opened at the cross beam of the vehicle.

[0036] Refer to the appendix Figures 2-4, a locking component 4 for stably connecting the mounting base 3 and the mounting cavity 37 is arranged inside the detection table 1, that is, the mounting base 3 and the detection table 1 can be conveniently disassembled and assembled. The locking component 4 includes a connecting cavity 41. The connecting cavity 41 is opened on the inner wall of the mounting cavity 37. A locking screw 42 is rotatably arranged on one side of the detection table 1, and one end of the locking screw 42 is rotatably arranged inside the connecting cavity 41. A locking block 43 is threadedly sleeved on the outer wall of one end of the locking screw 42 located inside the connecting cavity 41. The locking block 43 is slidably limited inside the connecting cavity 41. One end of the locking block 43 is clamped inside the mounting base 3. A locking groove 44 for limiting and clamping the locking block 43 is opened on one side of the mounting base 3. By rotating the locking screw 42, the locking block 43 threadedly connected to its outer wall moves. When one end of the locking block 43 is inserted into the locking groove 44, the mounting base 3 is fixed inside the mounting cavity 37, and with reference to the appendix Figure 2 , the detection table 1 is provided with multiple columns of mounting cavities 37, and a set of locking components 4 can lock between the mounting base 3 and the mounting cavity 37 located in the same column.

[0037] One side of the detection table 1 is provided with a control component 5. The control component 5 is used for fixing between the locking screw 42 and the detection table 1. The control component 5 includes a threaded cylinder 51 fixedly arranged on one side of the detection table 1 and a threaded ring 52 threadedly sleeved on the outer wall of the locking screw 42. One end of the threaded ring 52 is threadedly inserted into the threaded cylinder 51. Thread teeth are provided on both the outer wall and the inner wall of the threaded ring 52. The threaded ring 52 is threadedly connected to the inner wall of the threaded cylinder 51 through the thread teeth on its outer wall, and the threaded ring 52 is threadedly connected to the outer wall of the locking screw 42 through the thread teeth on its inner wall.
