[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As Figures 1-5 shown, a high-precision vehicle front crossbeam inspection fixture includes a bottom plate 1. A motor 2 is connected to the upper surface of the bottom plate 1. The output shaft end of the motor 2 is connected to a rotating rod 3. The output shaft end of the motor 2 drives the rotating rod 3 to rotate, providing power for the rotating rod 3 and facilitating operation. The top end of the rotating rod 3 is connected to a rotating block 4. The upper surface of the rotating block 4 is rotatably connected to a connecting rod 5.

[0024] One end of the connecting rod 5 is rotatably connected to a moving plate 6. There are two connecting rods 5 in total. The two connecting rods 5 drive the two moving plates 6 to move, and the distances moved by the two moving plates 6 are the same. An auxiliary column 12 is connected to the upper surface of the rotating block 4. The upper surface of the auxiliary column 12 is rotatably connected to an auxiliary ring 13. The outer surface of the auxiliary ring 13 is connected to the outer surface of the connecting rod 5. When the rotating block 4 drives the connecting rod 5 to rotate, the auxiliary ring 13 will rotate on the outer surface of the auxiliary column 12. At the same time, an auxiliary ring 13 and an auxiliary column 12 are also provided at the connection between the connecting rod 5 and the moving plate 6.

[0025] The upper surface of the moving plate 6 is connected to a right-angled plate 7. The upper surface of the bottom plate 1 is connected to a thick rod 14. The upper surface of the thick rod 14 is connected to a sliding seat 15. A chute 16 is provided on the upper surface of the sliding seat 15. The shape of the chute 16 is concave-convex, which can better limit the moving plate 6. The bottom surface of the moving plate 6 is connected to a sliding plate 17. The outer surface of the sliding plate 17 is slidably connected to the inner wall of the chute 16. Lubricating oil is applied to the inner wall of the chute 16, which can reduce the friction between the sliding plate 17 and the chute 16 and facilitate the sliding of the sliding plate 17 on the inner wall of the chute 16. The shape of the sliding plate 17 is also concave-convex, which can well contact the outer shape of the chute 16.

[0026] The outer surface of the right-angled plate 7 is connected to a fixing plate 8. When the moving distances of the two moving plates 6 are the same, the moving distances of the two fixing plates 8 will also be the same. The outer surface of the sliding seat 15 is bolted with a blocking block 18. The blocking blocks 18 are distributed on the front and rear surfaces of the sliding seat 15. There are four blocking blocks 18 in total, two in a group. The existence of the blocking blocks 18 is to prevent the sliding plate 17 from detaching from the chute 16.

[0027] The upper surface of the bottom plate 1 is connected to a fixing column 9. The outer surface of the fixing column 9 is connected to a base plate 10. A profile detection line 11 is provided on the upper surface of the base plate 10. There are two fixing plates 8 in total, symmetrically distributed on the upper surface of the base plate 10. The position of the front cross beam fixed by the fixing plate 8 is located at the center of the profile detection line 11. The front cross beam can be directly detected by referring to the profile detection line 11.

[0028] The bottom surface of the fixing plate 8 is slidably connected to the upper surface of the base plate 10. A support frame 19 is provided above the bottom plate 1. The outer surface of the rotating rod 3 rotatably penetrates through the outer surface of the support frame 19. The upper surface of the support frame 19 is connected to the outer surface of the sliding seat 15. The support frame 19 has a supporting effect on the rotating rod 3. The support frame 19 is composed of a plate and columns, consisting of one plate and four columns.

[0029] It should be noted that in actual use of this device, when detecting the front cross beam, place the front cross beam on the base plate 10, start the motor 2, the output shaft end of the motor 2 drives the rotating rod 3 to rotate, the rotating rod 3 drives the rotating block 4 to rotate, the rotating block 4 drives the connecting rod 5 to rotate, the connecting rod 5 pulls the moving plate 6 to move. At this time, the sliding plate 17 will slide on the inner wall of the chute 16. The chute 16 limits the movement of the sliding plate 17, so that the sliding plate 17 can only move horizontally along the direction of the chute 16. Thus, the fixing plate 8 is driven by the right-angled plate 7 to move horizontally to fix the front cross beam. The position of the fixed front cross beam is located at the center of the profile detection line 11. The front cross beam can be detected by referring to the profile detection line 11.

Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments, and what is described in the above-mentioned embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
