[0002] Car through-type headlights are a unique and increasingly popular automotive lighting design. Through-type headlights are the lighting elements of the front part of the car that are connected to the center grille to form a very integrated through-type shape. This design not only enhances the overall sense of the front face of the car, but also provides a unique visual appeal.

[0003] Like ordinary headlights, through-type headlights need to go through multiple processing steps during production, such as assembling light-emitting unit modules, high and low beam integrated modules, connectors, accessories, etc. Before assembly, the headlights generally need to be positioned and stabilized to ensure assembly accuracy. Due to the complex and irregular appearance of the headlights, the tooling structures for their positioning in the prior art are generally customized. However, the existing headlight positioning tooling is mostly manually positioned, which requires a large amount of manual participation and wastes manpower. In addition, the positioning accuracy is easily affected by looseness, and the rigid contact during positioning is likely to cause damage to the headlights.

[0004] Therefore, it is necessary to propose a through-type headlight assembly positioning tooling structure to solve the above problems. Utility Model Content

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-6 As shown, a through-type headlight assembly and positioning tooling structure includes a base 1, an automatic clamping mechanism is arranged on the top of the base 1, and the automatic clamping mechanism includes a bracket 4 arranged along the length direction of the base 1. The number of the brackets 4 is three, and the three brackets 4 correspond to the end and the middle of the headlight respectively. The upper end of the bracket 4 is provided with a lower positioning block 11 for supporting the bottom of the headlight and matching the shape of the headlight, one side of the upper end of the bracket 4 is movably connected with a cylinder 8, and the end of the output shaft at the top of the cylinder 8 is provided with a connecting seat 9, and the top end of the bracket 4 near the cylinder 8 is movably connected with a connecting arm 10, and the upper end of the connecting arm 10 is provided with a pressing frame 5, one end of the pressing frame 5 is movably connected to the connecting seat 9, and the bottom of the pressing frame 5 corresponding to the lower positioning block 11 is provided with an upper positioning block 12 for pressing the top of the headlight and matching the shape of the headlight;

[0025] In order to increase the stability of the headlight, grooves 17 are provided on the opposite sides of the upper positioning block 12 and the lower positioning block 11, and the groove 17 is movably connected with a floating block 15. A spring 18 is vertically provided between the floating block 15 and the inner wall of the groove 17, and when the spring 18 is in the initial state, the floating block 15 protrudes from the ends of the lower positioning block 11 and the upper positioning block 12. In order to avoid rigid damage, rubber pads 16 are provided at the adjacent ends of the lower positioning block 11 and the upper positioning block 12.

[0026] In addition, it also includes a positioning and centering mechanism, which includes a bidirectional screw rod 6 rotatably connected to the bottom of the base 1, one end of the bidirectional screw rod 6 extends to the outside of the base 1 and is provided with a handwheel 14 for driving the bidirectional screw rod 6 to rotate, and both ends of the bidirectional screw rod 6 are symmetrically threadedly connected with moving blocks 7, and both ends of the base 1 are provided with through grooves 3 corresponding to and adapted to the moving block 7, and the upper end of the moving block 7 is slidably matched with the inner wall of the through groove 3, and the two ends of the top of the base 1 are respectively slidably connected with positioning end plates 2 corresponding to the moving block 7, and the upper end of the moving block 7 extends to the top of the base 1 through the through groove 3 and is fixedly connected to the bottom of the positioning end plate 2.

[0027] In order to increase the stability of the positioning end plates 2 , triangular support plates 13 are fixedly provided on opposite sides of the two positioning end plates 2 , and the bottoms of the support plates 13 and the positioning end plates 2 are flush.

[0028] It should be noted that the utility model is a through-type headlight assembly positioning tooling structure. When in use, multiple cylinders 8 control multiple press frames 5 to open, two positioning end plates 2 are moved away, and the headlight is placed on the lower positioning block 11 on the top of multiple brackets 4, and then the hand wheel 14 is screwed to drive the two-way screw rod 6 to rotate, and the two-way screw rod 6 drives the two positioning end plates 2 to move closer through the moving block 7. The support plate 13 can increase the stability of the positioning end plates 2. The two positioning end plates 2 push the headlight to the center, and then the multiple cylinders 8 drive the press frame 5 through the action of the connecting seat 9 and the connecting arm 10. Press down, the upper positioning block 12 at the bottom of the pressure frame 5 cooperates with the lower positioning block 11 to clamp the headlight, and the floating block 15 contacts the headlight first when clamping. As the clamping is carried out, the floating block 15 will move toward the groove 17 and compress the spring 18. The spring 18 generates a reverse force until the rubber pad 16 at one end of the lower positioning block 11 and the floating block 15 is tightly fitted with the headlight. If there is a slight looseness, the spring 18 will reset for a while due to the reverse force, and the floating block 15 will move to fill the loose gap. The reverse force also exists, and the looseness of the headlight can be reduced under the reverse force.
