[0001] This utility model relates to the field of automotive lamp assembly technology, specifically to an auxiliary assembly tooling for assembling automotive lamp housings. Background Technology

[0002] Automotive headlights mainly consist of a lamp housing, a lamp cover, and a light-emitting element. The light-emitting element is generally installed in the mounting groove of the lamp housing, while the lamp cover and the lamp housing are connected by sealant. After the sealant cools, the lamp cover and the lamp housing are fixed together. Then, the headlight can be tested for air tightness using an air tightness testing device to ensure that the connection between the lamp cover and the lamp housing is tight.

[0003] Before conducting the airtightness test, workers typically place the pre-installed headlights in the workshop and allow the sealant to cool naturally. However, this method has limitations in cooling efficiency and affects the overall assembly efficiency. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an auxiliary assembly tool for assembling vehicle headlight housings, which can improve the cooling rate of the headlights and thus improve the overall assembly efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary assembly fixture for assembling vehicle headlight housings, comprising a base, a support frame fixed on the base, a mounting plate for placing headlights connected to the support frame, multiple mounting plates evenly distributed circumferentially, an upwardly extending support rod on the base, a mounting frame fixed to the top of the support rod, a fan connected to the mounting frame, multiple fans spaced apart from each other, and the mounting plates can be moved sequentially to positions vertically opposite to the fans, so that the airflow from the fans can be fully directed towards the headlights on each mounting plate, thereby improving the cooling efficiency of the headlights.

[0006] The present invention is further configured as follows: a rotating shaft is rotatably connected to the inner side of the support frame, and bases are fixedly fitted at both ends of the rotating shaft. A connecting frame is provided on the outer periphery of the base, and a connecting rod is provided between the connecting frame and the base. There are multiple connecting rods evenly distributed around the circumference. One end of the connecting rod is fixed to the base, and the other end extends toward the connecting frame as a connecting end. The connecting end is fixed to the connecting frame. A connecting arm is provided between the placement plate and the connecting rod. One end of the connecting arm is rotatably connected to the end of the placement plate, and the other end is rotatably connected to the connecting end. A drive motor is provided on the outer side of the support frame. The drive motor is used to drive the rotating shaft to rotate. Counterweights are symmetrically fixed on the placement plate, and the counterweights are provided with placement slots for mounting the end of the headlight.

[0007] The present invention is further configured such that: a limiting clamp is symmetrically fixed on the counterweight block, and the limiting clamp can move in a direction toward or away from the placement groove to adapt to headlights of different widths.

[0008] The present invention is further configured such that: a guide seat is fixed on the counterweight block, the guide seat is provided with a guide groove adapted to the limiting clamp block, the limiting clamp block is coupled to the guide groove and can form a sliding fit between the two, a plurality of limiting holes are provided in the guide groove and spaced apart from each other, the limiting clamp block is provided with a liftable insertion rod, and a spring is provided between the insertion rod and the guide block, the spring being used to provide pressure to the insertion rod so that the insertion rod is stably inserted into the limiting hole.

[0009] The present invention is further configured such that: the placement plate is provided with through ventilation slots, and there are multiple ventilation slots spaced apart from each other.

[0010] The present invention is further configured such that: the mounting frame is provided with a plurality of first threaded holes spaced apart from each other; the outer side of the fan is provided with a connecting flange; the connecting flange is provided with a through second threaded hole; and the second threaded hole is opposite to the first threaded hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] Because multiple placement plates are provided for placing the assembled headlights, and fans are installed above the placement plates, the headlights can be placed on the placement plates after assembly. By moving each placement plate sequentially to a position vertically opposite to the fan, the airflow blown by the fan can be fully directed to the headlights on each placement plate, improving the cooling efficiency of the headlights. Therefore, this effectively solves the technical problem of slow cooling efficiency of the sealant in the headlights by natural cooling in the prior art, thereby improving the cooling rate of the headlights and improving the overall assembly efficiency.

[0017] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] like Figures 1 to 4 As shown, this utility model discloses an auxiliary assembly fixture for assembling headlight housings, including a base 1, a support frame 2 vertically fixed on the base 1, a horizontally arranged rotating shaft 7 rotatably connected to the inner side of the support frame 2 via bearings, and annular bases 8 fixedly fitted at both ends of the rotating shaft 7. The outer circumference of the base 8 is fixedly connected to an annular connecting frame 9 on the outer circumference of the base 8 via multiple evenly distributed circumferential connecting rods 10. The connecting frame 9 has a connecting end corresponding to the end of each connecting rod 10, and the connecting end is rotatably connected to the end of a placement plate 3 located above the base 1 via a hinged connecting arm 11. There are multiple placement plates 3, for example four, evenly distributed along the circumference. Each placement plate 3 is symmetrically fixed with a cast iron counterweight 13, and the top of the counterweight 13 has a placement groove 131 for mounting the two ends of the headlight housing. The placement plate 3 also has multiple through-type strip ventilation grooves 31, which are spaced apart along the length of the placement plate 3 to enhance the penetration of cooling airflow. A drive motor 12 is installed on the outside of the support frame 2. The output shaft of the drive motor 12 is connected to the rotating shaft 7 through a gear set. When the drive motor 12 starts, the rotating shaft 7 drives the connecting frame 9 and the placement plate 3 to rotate at a constant speed, so that each placement plate 3 passes through a specific position in sequence.

[0020] In addition, a support rod 4 is vertically fixed on the base 1. A rectangular mounting frame 5 is welded to the top of the support rod 4. Multiple spaced fans 6 are connected to the top of the mounting frame 5, with the air outlets of the fans 6 facing downwards and directly opposite the placement plate 3. Specifically, the mounting frame 5 has multiple first threaded holes 51 arranged along its length. The edge of the fan 6 housing has a connecting flange 61, and the connecting flange 61 has second threaded holes 611 corresponding to the first threaded holes 51. By passing bolts through the second threaded holes 611 and tightening them with the first threaded holes 51, the fans 6 can be fixed in the designated position of the mounting frame 5, thereby adjusting the spacing of the fans 6 to accommodate placement plates 3 of different sizes and facilitating the installation and removal of the fans 6. When the placement plate 3 rotates with the rotating shaft 7, each placement plate 3 will move sequentially to directly below the fan 6. At this time, the airflow blown out by the fan 6 acts directly on the headlight surface through the ventilation slot 31, achieving uniform and efficient cooling to accelerate the curing rate of the sealant at the connection between the lamp cover and the lamp housing in the headlight. The counterweight design ensures that the headlights on the placement plate 3 always face the upward-facing fan 6 under the influence of gravity during rotation.

[0021] Furthermore, symmetrical limiting clamps 14 are further provided on both sides of the counterweight 13. The limiting clamps 14 can slide horizontally to accommodate headlights of different widths, preventing the size of the placement slot 131 from being too large for the headlights at both ends, which would cause excessive wobbling when the headlights are mounted in the placement slot 131. This ensures that the airflow from the fan 6 can be more concentrated towards the headlights. Specifically, a guide seat 15 is fixed on the counterweight 13, and a horizontally extending guide groove 151 is provided in the guide seat 15. The bottom of the limiting clamp 14 is embedded in the guide groove 151 and locked in position by the insertion rod 16 described below. The bottom of the guide groove 151 is provided with multiple spaced limiting holes 152. The limiting clamp 14 is provided with a liftable insertion rod 16 inside, and a compressible spring 17 is installed between the insertion rod 16 and the limiting clamp 14. The spring 17 forces the insertion rod 16 downward into the limiting hole 152 to fix the limiting clamp 14. During operation, by lifting the insertion rod 16 to disengage it from the limiting hole 152, the position of the limiting clamp 14 can be slidably adjusted. After being released, the insertion rod 16 is reinserted into the corresponding limiting hole 152 under the action of the spring 17 to complete the locking.

[0022] The implementation process for this solution is as follows:

[0023] During operation, the operator first slides the limiting clamps 14 on both sides according to the specifications of the headlight to ensure that the distance between the limiting clamps 14 on both sides matches the specifications of the headlight end. Then, the two ends of the headlight can be placed in the placement slots 131 of the counterweight 13. After starting the drive motor 12, the placement plate 3 drives the headlight to rotate at a constant speed, and each fan 6 blows air to cool the headlight passing below it in turn.

[0024] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
