Description

Technical Field

[0001] This utility model relates to the field of vehicle lamp assembly technology, and more specifically, to a vehicle lamp positioning and assembly fixture. Background Technology

[0002] With social progress and economic development, automobiles have now become very common in people's lives. Automobiles have become an indispensable means of transportation in human society. Car lights refer to the lights on a vehicle. Car lights mainly serve the functions of illumination and signaling. Car light assembly fixtures are auxiliary tools specially designed for the assembly process of car lights, aiming to ensure that car light components can be assembled onto the car accurately and efficiently.

[0003] The existing positioning clamps for car headlights cannot rotate, which means that when assembling the other side of the car headlight, it is necessary to remove the car headlight again for clamping and positioning, thus greatly reducing work efficiency.

[0004] A search revealed that Chinese patent CN220838838U discloses an assembly device for automotive headlights. In use, the headlight to be assembled is placed inside a fixed frame. Then, a threaded rod is rotated. Because the clamping plate is connected to one end of the threaded rod via a bearing, and the other end of the threaded rod passes through and is threaded to the fixed frame, rotating the threaded rod causes the clamping plate to move. This allows the two clamping plates to clamp and position the headlight. A first servo motor is then activated, driving a rotating shaft to rotate. This rotating shaft, in turn, causes the fixed frame and connecting shaft to rotate, facilitating the rotation of the clamped headlight and allowing for easy assembly of the other side of the headlight without needing to remove it for re-clamping and positioning.

[0005] In actual use, when the above-mentioned assembly device for automotive headlights is used to fix the round headlight onto the clamp, the lack of a positioning device for the headlight during clamping can cause it to shake or shift, resulting in a deviation in the placement of the headlight and thus an inaccurate position of the assembled headlight. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a vehicle lamp positioning and assembly fixture to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A vehicle headlight positioning and assembly fixture includes an assembly table, a base fixedly connected to the upper surface of the assembly table, a support frame fixedly connected to the top of the assembly table, a cylinder mounted on the top of the support frame, a connecting frame fixedly connected to the output end of the cylinder, a fixed plate fixedly connected to the bottom of the connecting frame, a positioning component mounted inside the bottom of the fixed plate, and a clamping mechanism mounted on the top of the assembly table.

[0009] The positioning component includes a stepper motor, which is fixedly connected to the upper surface of the fixed disk. A turntable is fixedly connected to the output end of the stepper motor. A connecting rod is rotatably connected to the bottom end of the turntable. A connecting column is rotatably connected to one end of the connecting rod. A first sliding block is fixedly connected to the bottom end of the connecting column. A rotating rod is rotatably connected to the bottom end of the first sliding block. A positioning bracket is fixedly connected to the bottom end of the rotating rod. Two rollers are rotatably connected to the front side of the positioning bracket. Three first sliding grooves are formed on the lower surface of the fixed disk. The inner side of the first sliding groove is slidably connected to the first sliding block. Three positioning pins are fixedly connected to the bottom end of the fixed disk.

[0010] By adopting the above technical solution, positioning the vehicle headlight on the front side of the clamp can effectively prevent shaking and displacement during clamping, and reduce quality problems caused by movement during clamping.

[0011] As a further description of the above technical solution: the clamping mechanism includes an electric push rod, the output end of which is fixedly connected to a connecting plate, and the top of the connecting plate is fixedly connected to three first hinge supports. A pull rod is hinged to the inner side of each first hinge support, and a second hinge support is hinged to one end of the pull rod. A second hinge support is fixedly connected to the upper surface of the second hinge support, and a second slider is fixedly connected to the top of the second hinge support. A clamping ring is fixedly connected to the upper surface of the second slider, and an anti-slip pad is fixedly connected to the front side of the clamping ring. Three second sliding grooves are provided on the upper surface of the assembly table, and the inner side of each second sliding groove is slidably connected to the second slider.

[0012] By adopting the above technical solution, the headlights are clamped in a triangle using three clamping rings, resulting in greater stability when clamping them.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. By setting up a positioning component, compared with the existing technology, the headlight can be positioned before clamping, so that the headlight can remain stable during clamping, reducing the time and error of manual adjustment, and allowing the headlight to be placed more accurately on the base during assembly. This reduces quality problems caused by movement during clamping and improves the overall assembly quality.

[0015] 2. By setting up a clamping mechanism, compared with the existing technology, the vehicle headlight is clamped by three clamping rings in a triangle, which makes the vehicle headlight more stable when clamping it. It can effectively maintain the stable position of the vehicle headlight and prevent it from moving or falling off, thereby ensuring the accuracy and safety of assembly. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The embodiments disclosed in this application are as follows: Figure 1-6The above-displayed vehicle headlight positioning assembly fixture includes an assembly table 1, a base 5 fixedly connected to the upper surface of the assembly table 1, a support frame 2 fixedly connected to the top of the assembly table 1, a cylinder 3 installed at the top of the support frame 2, a connecting frame 4 fixedly connected to the output end of the cylinder 3, a fixed plate 6 fixedly connected to the bottom end of the connecting frame 4, a positioning component installed inside the bottom end of the fixed plate 6, and a clamping mechanism installed at the top of the assembly table 1.

[0025] The positioning assembly includes a stepper motor 7, which is fixedly connected to the upper surface of a fixed disk 6. A turntable 8 is fixedly connected to the output end of the stepper motor 7. A connecting rod 9 is rotatably connected to the bottom end of the turntable 8. A connecting post 10 is rotatably connected to one end of the connecting rod 9. A first sliding block 11 is fixedly connected to the bottom end of the connecting post 10. A rotating rod 12 is rotatably connected to the bottom end of the first sliding block 11. A positioning bracket 13 is fixedly connected to the bottom end of the rotating rod 12. Two rollers 14 are rotatably connected to the front side of the positioning bracket 13. Three first sliding grooves 15 are formed on the lower surface of the fixed disk 6. The inner side of each first sliding groove 15 is slidably connected to the first sliding block 11. Three positioning pins 16 are fixedly connected to the bottom end of the fixed disk 6. The three connecting rods 9 are used to... The ends rotate with turntable 8 and connecting column 10 respectively, so that when turntable 8 deflects, it can drive the three connecting rods 9 to move. One end of the connecting rod 9 can pull the first sliding block 11 to slide inside the first sliding groove 15, so that the first sliding block 11 can stably drive the positioning bracket 13 to contact the surface of the car lamp. Two rollers 14 are used to assist the positioning bracket 13 in contacting the surface of the car lamp, so that when the three positioning brackets 13 contact the round car lamp, they can position the round car lamp on the base 5. The positioning pin 16 is used to prevent the positioning bracket 13 from deflecting at a large angle, so that the three positioning brackets 13 can position the car lamp before clamping, so that the car lamp can remain stable when clamped.

[0026] Reference Figure 4 and 6As shown, the clamping mechanism includes an electric push rod 17, with a connecting plate 18 fixedly connected to the output end of the electric push rod 17. Three first hinge supports 19 are fixedly connected to the top of the connecting plate 18. A pull rod 20 is hinged to the inner side of each first hinge support 19. A second hinge support 21 is hinged to one end of the pull rod 20. A second hinge support 21 is fixedly connected to the upper surface of the second hinge support 21. A second slider 22 is fixedly connected to the top of the second hinge support 21. A clamping ring 23 is fixedly connected to the upper surface of the second slider 22. An anti-slip pad 24 is fixedly connected to the front side of the clamping ring 23. Three second sliding grooves 2 are formed on the upper surface of the assembly table 1. 5. The inner side of the second slide groove 25 is slidably connected to the second slider 22. The downward movement of the connecting plate 18 can drive the three first hinge supports 19 to move downward. The two ends of the pull rod 20 are respectively hinged to the inner sides of the first hinge support 19 and the second hinge support 21, so that the connecting plate 18 can drive the three pull rods 20 to pull the second slider 22 to slide inside the second slide groove 25. This allows the three second sliders 22 to drive the clamping ring 23 to clamp the outer side of the headlight. The three clamping rings 23 clamp the headlight in a triangle, which can effectively maintain the stable position of the headlight and prevent it from moving or falling off.

[0027] Working principle of this utility model: This utility model designs a vehicle headlight positioning and assembly fixture, the specific structure of which is shown in the attached instruction manual. Figure 1-6 As shown, in this technical solution, through the cooperation between various structures, when assembling the round headlight, the round headlight is first placed on the base 5. Then, the cylinder 3 is activated, which pushes the connecting frame 4 downward, allowing the connecting frame 4 to move the fixing plate 6 downward, thereby moving the three positioning brackets 13 to the outside of the round headlight. Then, the stepper motor 7 is activated, which drives the turntable 8 to deflect. The two ends of the connecting rod 9 are rotatably connected to the turntable 8 and the connecting column 10 respectively, so that when the turntable 8 deflects, it can drive one end of the connecting rod 9 to move, so that the other end of the connecting rod 9 passes through the connecting column. 10 can drive the first sliding block 11 to slide inside the first sliding groove 15 so that the positioning bracket 13 can contact the surface of the round headlight. By rotating the rod 12 and the bottom end of the first sliding block 11, the positioning bracket 13 can deflect and swing when it approaches the round headlight. The two rollers 14 are used to assist the positioning bracket 13 in contacting the headlight surface, so that the three positioning brackets 13 can position the round headlight on the base 5 when they contact the round headlight. The positioning pin 16 can limit the deflection angle of the positioning bracket 13, which can effectively prevent the positioning bracket 13 from deflecting.

[0028] Then, the electric push rod 17 is activated, which drives the connecting plate 18 to move downward. The two ends of the pull rod 20 are respectively hinged to the inner sides of the first hinge support 19 and the second hinge support 21, so that when the connecting plate 18 moves downward, the three pull rods 20 can pull the second slider 22 to move. The second slider 22 is slidably connected to the inner side of the second slide groove 25, which can guide the movement of the second slider 22, so that the second slider 22 can drive the three clamping rings 23 to clamp the headlight. After clamping is completed, the stepper motor 7 is activated again, so that the stepper motor 7 rotates in the opposite direction, thereby separating the three positioning brackets 13 from the headlight surface, and driving the fixed plate 6 to move upward through the cylinder 3, which facilitates the assembly work.
