Technical Field
[0001] This utility model relates to the field of automotive parts installation technology, specifically an auxiliary tooling for precise alignment and installation of headlights. Background Technology
[0002] In the process of refining automobile manufacturing and maintenance, the importance of headlight installation precision is becoming increasingly prominent. It is not only related to driving safety, but also has a decisive impact on the lighting effect. Precisely installed headlights can ensure that drivers are provided with clear and appropriate lighting under various road conditions and weather conditions, effectively avoiding safety hazards caused by deviations in the beam angle or unreasonable range, such as glare interfering with oncoming vehicles and insufficient lighting obstructing the driver's vision.
[0003] However, most existing headlight alignment and installation methods rely on fixed mounting frames for assistance. In actual installation, headlights often need to be angled according to the specific vehicle model, design requirements, and actual assembly conditions to achieve the optimal installation position and angle. However, fixed mounting frames, due to their inherent design limitations, lack flexibility and precise angle adjustment capabilities, making it difficult to meet the angle adjustment requirements during headlight installation and resulting in ineffective guarantee of installation accuracy. Therefore, we propose an auxiliary tooling for precise headlight alignment and installation. Utility Model Content

[0016] like Figures 1-4 As shown, an auxiliary tooling for precise alignment and installation of a headlight includes: a support base 1 and a support vertical rod 2 fixedly installed at the upper center of the support base 1. An adjusting sleeve 3 is movably sleeved at the upper center of the support vertical rod 2. Support suspension rods 4 are rotatably installed at the centers of both sides of the adjusting sleeve 3. An angle adjustment mechanism 5 is fixedly installed at one end of the support suspension rod 4. The angle adjustment mechanism 5 is used to rotatably install a clamping mechanism 6, which is used to clamp the headlight.
[0017] In practice, the support base 1 has multiple sets of casters installed at its bottom, allowing the fixture components to be moved to the desired installation position during headlight installation. The casters are then locked in place by a locking mechanism to prevent movement during installation. The support rod 2 is vertically fixed to the support base 1, connecting and supporting the upper adjustment structure. The adjusting sleeve 3 is movably fitted onto the support rod 2, allowing for height adjustment by moving it up and down. The support suspension rod 4 is rotatably mounted on both sides of the adjusting sleeve 3, allowing for adjustment of the headlight's horizontal position. The support suspension rod 4 can also extend the installation range, adapting to different headlight installation distances for various vehicle models. The angle adjustment mechanism 5 is installed at one end of the support suspension rod 4, enabling precise adjustment of the headlight installation angle. The clamping mechanism 6 is installed within the angle adjustment mechanism 5, clamping headlights of different sizes to ensure accurate alignment with the installation position.
[0018] As a technical optimization of this utility model, the angle adjustment mechanism 5 includes an adjustment shaft seat 51 horizontally rotatably installed at one end of the support suspension rod 4. An upper arc-shaped support rod 52 is fixedly installed at the lower end of one side of the outer wall of the adjustment shaft seat 51. A fixed mounting block 53 is fixedly installed at the lower end of the upper arc-shaped support rod 52. An upper adjustment shaft 54 is vertically rotatably installed at the center of one side of the fixed mounting block 53. A lower arc-shaped support rod 55 is fixedly installed at the lower end of the outer wall of the upper adjustment shaft 54. A lower adjustment shaft 56 is fixedly installed at one end of the lower arc-shaped support rod 55. A movable shaft 57 is rotatably installed at the center of the upper end of the lower adjustment shaft 56. The rotation surface of the movable shaft 57 is perpendicular to the rotation surface of the upper adjustment shaft 54.
[0019] In practice, the adjusting shaft seat 51 can rotate around the end of the supporting suspension rod 4, realizing the horizontal rotation of the entire angle adjustment mechanism 5; the upper arc-shaped support rod 52 adopts an arc design, and its arc structure helps to realize the flexibility of angle adjustment; the fixed mounting block 53 serves as a connecting hub, stably connecting the upper arc-shaped support rod 52 to the next-level adjustment component; the upper adjusting shaft 54 can rotate around the fixed mounting block 53, driving the lower arc-shaped support rod 55 to adjust the angle; the lower arc-shaped support rod 55 cooperates with the upper arc-shaped support rod 52 to form a double-layer arc-shaped adjustment structure, expanding the angle adjustment range; the lower adjusting shaft 56 provides rotational support for the movable shaft 57, and the movable shaft 57 can realize multi-angle fine adjustment of the clamping mechanism 6, adapting to the complex installation angle requirements of the headlight.
[0020] As a technical optimization of this utility model, the clamping mechanism 6 includes an arc-shaped mounting plate 61 fixedly installed at the upper end of the movable shaft 57. A mounting seat 62 is fixedly installed at the center of one end of the arc-shaped mounting plate 61. A double screw rod 63 is rotatably installed at the center of the inner side of the mounting seat 62. An adjusting handle 64 is fixedly installed at one end of the double screw rod 63. The double screw rod 63 includes two sections of threads with opposite rotation directions. Nut seats 65 are symmetrically rotatably installed on the outer side of the double screw rod 63. An arc-shaped groove is opened at the center of the inner side of the nut seat 65. Multiple sets of mutually interlocking universal clamping heads 66 are rotatably installed on the inner side of the arc-shaped groove. A sliding block 67 is fixedly installed on the outer side of the multiple sets of mutually interlocking universal clamping heads 66. The sliding block 67 is in contact with the arc-shaped groove.
[0021] In practice, the arc-shaped mounting plate 61 adapts to the arc-shaped contour of the headlight, providing a fitting mounting base for the clamping components; the mounting base 62 is used to fix the double screw rod 63, ensuring its stable rotation; the double screw rod 63 adopts a bidirectional thread design, which can drive the two nut seats 65 on both sides to move closer or further away simultaneously when rotated; when the operator manually rotates the adjusting handle 64, the nut seat 65 will move along the double screw rod 63, and the arc-shaped sliding groove is opened at the center of the inner side of the nut seat 65, providing installation and sliding space for the universal clamping head 66. Multiple sets of interlocking universal clamping heads 66 are arc-shaped. The universal clamping head 66 is rotatably mounted inside the arc-shaped slide groove and can be flexibly adjusted according to the shape of the headlight to clamp headlights of different shapes. The sliding block 67 is fixed to the outer wall of the universal clamping head 66 and fits into the arc-shaped slide groove to ensure that the universal clamping head 66 slides stably in the arc-shaped slide groove so that it can fit the curved surface of the headlight. Multiple sets of interlocking universal clamping heads 66 can flexibly adjust the clamping angle to ensure stable clamping of headlights with different curved contours. The sliding block 67 can prevent the universal clamping head 66 from falling off the arc-shaped slide groove and ensure the stability of the clamping structure.
[0022] As a technical optimization of this utility model, the inner side wall of the adjusting sleeve 3 is provided with an axial limiting groove, and the outer side wall of the supporting vertical rod 2 is provided with a limiting protrusion corresponding to the axial limiting groove. The limiting protrusion and the axial limiting groove are slidably adapted. A locking bolt is threaded through the side wall of the adjusting sleeve 3. The end of the locking bolt abuts against the outer side wall of the supporting vertical rod 2 for fixation. An elastic buffer layer is provided at the end of the universal clamping head 66 away from the sliding block 67. The surface of the elastic buffer layer is provided with anti-slip texture. An arc-shaped transition surface is provided at the fitting point of two adjacent sets of universal clamping heads 66.
[0023] In specific implementation, the axial limiting groove is opened on the inner side wall of the adjusting sleeve 3, and the limiting protrusion is set at the corresponding position on the outer side wall of the supporting vertical rod 2. The two slide and adapt to each other, which can prevent the adjusting sleeve 3 from rotating when moving up and down along the supporting vertical rod 2, ensuring the stability of adjustment. The locking bolt is threaded through the side wall of the adjusting sleeve 3. When the adjusting sleeve 3 moves to a suitable height, the locking bolt is tightened so that its end abuts against the outer side wall of the supporting vertical rod 2, thereby fixing the adjusting sleeve 3 on the supporting vertical rod 2 and preventing it from sliding down. The elastic buffer layer is set at the end of the universal clamping head 66 away from the sliding block 67. When it comes into contact with the headlight, it can play a buffering role to avoid damage to the headlight. The anti-slip texture is set on the surface of the elastic buffer layer, which can increase the friction between it and the headlight and prevent the headlight from slipping during clamping. The arc transition surface is set at the fitting point of the two adjacent sets of universal clamping heads 66, making the universal clamping heads 66 more smooth when fitting, reducing wear on the surface of the headlight, and also helping to better fit the shape of the headlight.
[0024] Working principle: First, move the support base 1 to the target position using the bottom casters and lock it to ensure the overall stability of the fixture. Then, slide the adjusting sleeve 3 up and down along the support vertical rod 2. The limiting protrusion on the outside of the support vertical rod 2 and the axial limiting groove on the inside of the adjusting sleeve 3 can be slidably matched to prevent the adjusting sleeve 3 from rotating. After adjusting to the height suitable for the installation of the headlight, tighten the locking bolts on the side wall of the adjusting sleeve 3 so that its end abuts against and is fixed to the support vertical rod 2. At the same time, rotate the support suspension rods 4 on both sides of the adjusting sleeve 3 to adjust their horizontal unfolding angle and extension position to match the headlight spacing of the vehicle to be installed. Secondly, the angle adjustment mechanism 5 connected to the clamping mechanism 6 is rotated around the end of the support rod 4 via the adjustment shaft seat 51 to complete the initial angle adjustment in the horizontal direction. Then, the upper adjustment shaft 54 on the fixed mounting block 53 is rotated to drive the lower arc-shaped support rod 55 to rotate around the fixed mounting block 53 as the axis, which, together with the arc structure of the upper arc-shaped support rod 52, expands the adjustment range. Then, by rotating the lower adjustment shaft 56 at the end of the lower arc-shaped support rod 55, the movable shaft 57 is driven to rotate flexibly, so as to realize the fine angle adjustment of the clamping mechanism 6 in the vertical and tilt directions until it is aligned with the installation angle reference of the headlight. Finally, place the headlight to be installed inside the arc-shaped mounting plate 61, rotate the adjustment handle 64 on the mounting base 62 to rotate the double screw rod 63, and the symmetrical nut seats 65 on the outer side of the double screw rod 63 move closer to the rod body synchronously. The universal clamping head 66 in the arc-shaped slide groove inside the nut seat 65 slides along the slide groove through the sliding block 67. The multiple sets of interlocking universal clamping heads 66 adaptively adjust the angle according to the curvature of the headlight. The elastic buffer layer and anti-slip texture at the end can firmly clamp the headlight and avoid damage. After clamping and fixing, fine-tune the angle adjustment mechanism 5 again to ensure that the headlight is accurately aligned with the vehicle mounting position, and complete the final installation operation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
