[0054] In a device for positioning and clamping a headlight fixture of the utility model, a headlight fixture 28 and a main vehicle fixture 27 are positioned and connected by a main positioning pin 2, the main positioning pin 2 is positioned and connected to a first center hole 4 of a connecting sleeve 1, the connecting sleeve 1 is positioned and connected to the headlight fixture 28, and the main positioning pin 2 is positioned and connected to a second center hole 5 of a positioning sleeve 3, the positioning sleeve 3 is positioned and connected to the main vehicle fixture 27, so that the headlight fixture 28 is positioned and connected to the main vehicle fixture 27; and a clamping nut 9 is connected to the threaded section 6, the clamping nut 9 is clamped on the top of the connecting sleeve 1, and a hook 16 at the lower end of the main positioning pin 2 passes through the positioning sleeve 3 and hooks on the edge of the main positioning hole 26, so that the clamping nut 9 and the hook 16 clamp the headlight fixture 28 and the main vehicle fixture 27 together; it can be seen that a device for positioning and clamping a headlight fixture of the utility model can conveniently position and clamp the headlight fixture 28.

[0055] As a preferred embodiment, the third section positioning pin 15 is eccentrically arranged relative to the first section positioning pin 7, please refer to Figure 5 The main positioning pin 2 can also rotate to allow the hook 16 to rotate to a state where it can smoothly pass through the main positioning hole 26. Figure 6 As shown, the main positioning pin 2 rotates to allow the hook 16 to rotate to a state where it can hook the edge of the main positioning hole 26 .

[0056] Please refer to Figure 1 and Figure 2, a U-shaped groove 10 is provided on the side wall of the connecting sleeve 1, and the U-shaped groove 10 includes a first connecting groove 11 and a second connecting groove 12 parallel to the axis of the first center hole 4, and the bottoms of the first connecting groove 11 and the second connecting groove 12 are connected through a third connecting groove 13; a stopper pin 14 is provided on the side wall of the first section positioning pin 7, and the stopper pin 14 is located in the U-shaped groove 10; when the main positioning pin 2 rotates to the position located in the first connecting groove 11, the hook 16 rotates to a state where it can hook the edge of the main positioning hole 26; when the main positioning pin 2 rotates to the position located in the second connecting groove 12, the hook 16 rotates to a state where it can smoothly pass through the main positioning hole 26. Move the main positioning pin 2 downward along the first center hole 4 so that the stopper pin 14 enters the third connecting groove 13, and then the main positioning pin 2 can be rotated so that the stopper pin 14 rotates from the first connecting groove 11 to the second connecting groove 12, or rotates from the second connecting groove 12 to the first connecting groove 11.

[0057] As a preferred embodiment, Figure 2 As shown, the hook 16 is arranged at the lower end of a screw rod 17, and the upper end of the screw rod 17 is threadedly connected to the central screw hole 18 of the second section positioning pin 8. This can reduce the length of the main body of the main positioning pin 2, make it easier to process the main positioning pin 2, and make it more convenient to remove the hook 16.

[0058] In order to facilitate the positioning and installation of the connecting sleeve 1 with the vehicle lamp inspection fixture 28, as shown in FIG. Figure 1 , Figure 2 and Figure 3 As shown, the connecting sleeve 1 has a connecting flange 19, the bottom surface of the connecting flange 19 is positioned and matched with the top of the headlight inspection fixture 28, and two auxiliary pin holes 20 are provided on the connecting flange 19. Each auxiliary pin hole 20 is provided with an auxiliary positioning pin 21, and the auxiliary positioning pin 21 is used to plug into the two positioning holes on the top of the headlight inspection fixture 28 (not shown in the figure).

In this way, on the one hand, the positioning sleeve 3 and the transition positioning hole 22 of the headlight inspection fixture 28 can be well positioned, and on the other hand, the positioning sleeve 3 can be prevented from rotating when the main positioning pin 2 is rotated.

[0061] The third section positioning pin 15 is used to position the positioning sleeve 3 relative to the main positioning hole 26. Figures 4 to 6 The third section positioning pin 15 includes two positioning posts 24, the outer side of the positioning posts 24 is a positioning cylindrical surface, and the positioning cylindrical surface cooperates with the main positioning hole 26 on the main automobile inspection fixture 27, and the space between the two positioning posts 24 can accommodate the hook 16. In order to allow the positioning posts 24 to be smoothly inserted into the main positioning hole 26, as shown in FIG. Figure 4 As shown, a guiding cone surface 25 is provided at the lower end of the positioning column 24 .

[0062] The device for positioning and clamping a headlight inspection fixture of the utility model is a connected component, not a scattered part. When positioning and clamping the headlight inspection fixture 28, first loosen the clamping nut 9 so that the main positioning pin 2 moves downward relative to the positioning sleeve 3, and the hook 16 extends to a state where it can rotate freely without interfering with the positioning column 24. At this time, the stop pin 14 on the main positioning pin 2 is located in the second connecting groove 12, and then the main positioning pin 2 is withdrawn relative to the positioning sleeve 3 so that the stop pin 14 on the main positioning pin 2 is stuck in the second connecting groove 12, and the state where the stop pin 14 on the main positioning pin 2 is stuck in the second connecting groove 12 is maintained so that the hook 16 cannot rotate, and then the main positioning pin 2 is removed from the mounting hole ( Figure 2 Not marked, at the connecting sleeve 1) downward through the transition positioning hole 22 at the bottom of the headlight inspection fixture 28, and through the main positioning hole 26 on the main automobile inspection fixture 27. After the third section positioning pin 15 is positioned and matched with the main positioning hole 26, the main positioning pin 2 is moved downward so that the stop pin 14 moves to the third connecting groove 13, and the main positioning pin 2 is rotated so that the stop pin 14 enters the first connecting groove 11, and the stop pin 14 is kept stuck in the first connecting groove 11 and the main positioning pin 2 is retracted so that the hook 16 is hooked on the edge of the main positioning hole 26, and then the connecting sleeve 1 is positioned and fixed on the headlight inspection fixture 28, and then the clamping nut 9 is tightened, so that the hook 16 is pressed upward on the edge of the main positioning hole 26 so that the headlight inspection fixture 28 and the main automobile inspection fixture 27 are clamped.

[0063] Based on the technical solutions of the above embodiments, a device for positioning and clamping a headlight inspection fixture of the utility model can conveniently position and clamp the headlight inspection fixture, and is convenient to install and disassemble. Moreover, the positioning and clamping are both along the axis direction of the main positioning pin. Such a positioning and clamping method makes the positioning accuracy higher.

[0064] In summary, the utility model effectively overcomes various shortcomings of the prior art and has high industrial utilization value.

[0065] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
