Description

Technical Field

[0001] This utility model relates to the field of automotive lamp processing technology, and in particular to a tooling for aligning and pressing automotive lamp lenses and housings. Background Technology

[0002] In the manufacturing process of automotive lighting, the assembly of the lens and housing is a crucial step, as its accuracy directly affects the lamp's sealing performance, optical performance, and overall structural stability. To ensure precise alignment and reliable pressing between the lens and housing, alignment and pressing fixtures are widely used in the industry to complete this process.

[0003] Currently, existing automotive lamp lens and housing alignment and pressing fixtures can generally achieve good positioning and pressing operations between the lens and housing. The positioning system ensures precise alignment between the two, and the pressing system applies uniform and stable pressure to meet assembly requirements. However, after pressing, the automotive lamp assembly is usually still on the lower mold, making it inconvenient to move the automotive lamp housing upwards and push it out of the mold. If the automotive lamp housing needs to be removed, it often requires manual operation, which not only increases the labor intensity of the operators, but also easily causes relative displacement between the assembled lens and housing due to improper force or negligence during the removal process, destroying the previous precise alignment, and even causing adverse consequences such as lens scratches and housing deformation, seriously affecting product quality. Therefore, this utility model proposes an alignment and pressing fixture for automotive lamp lenses and housings to solve the above problems. Utility Model Content

[0004] To address the aforementioned issues, this utility model proposes a tooling for aligning and pressing a vehicle headlight lens and its housing, which solves the problem in the prior art that it is inconvenient to move the headlight housing upwards and push it out of the project.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a tooling for aligning and pressing a vehicle headlight lens and a housing, including a base plate, a lower mold mounted on the top of the base plate, a replacement mechanism provided below the lower mold, a placement groove opened inside the lower mold, a pushing mechanism provided inside the lower mold, a fixing rod mounted on the rear end of the top of the base plate, a top plate mounted on the top of the fixing rod, a hydraulic cylinder mounted on the top of the top plate, the output end of the hydraulic cylinder extending to the bottom of the top plate, a fixing plate mounted on the bottom of the hydraulic cylinder, an mounting plate mounted on the bottom of the fixing plate, and a pressing plastic head mounted on the bottom of the mounting plate.

[0006] A further improvement is made in that: the pushing mechanism includes a fixed cavity, a pushing plate, a servo motor, a threaded rod, a threaded sleeve, a movable cavity, and a limiting structure. The fixed cavity is installed at the top of the base plate, and the servo motor is installed at the bottom of the fixed cavity. The threaded rod is installed inside the fixed cavity, and the output end of the servo motor is connected to one end of the threaded rod. A threaded sleeve is provided on the outer wall of the threaded rod, and a movable cavity is fixedly installed on the outer wall of the threaded sleeve. The pushing plate is installed at the top of the movable cavity, and an avoidance hole for avoiding the pushing plate is provided at the bottom of the placement groove. The limiting structure is used to limit the movement of the movable cavity.

[0007] A further improvement is that a sponge pad is provided above the pusher plate, and the sponge pad is used to protect the lens.

[0008] A further improvement is that the limiting structure includes a limiting groove and a limiting block. The limiting groove is formed on the inner wall of the fixed cavity, and the limiting block is provided inside the limiting groove. One end of the limiting block is connected to the outer side of the movable cavity.

[0009] A further improvement is that the cross-section of the limiting groove is larger than the cross-section of the limiting block, and the limiting groove and the limiting block form a sliding structure.

[0010] A further improvement is made in that: the replacement mechanism includes an installation cavity, a connecting rod, and a positioning pin. The installation cavity is installed at the top of the base plate, and the connecting rod is provided inside the installation cavity. The top of the connecting rod is connected to the bottom of the lower mold. The side walls of the installation cavity and the connecting rod are provided with pin holes for installing the positioning pin to achieve fixation between the installation cavity and the connecting rod.

[0011] A further improvement is that the mounting cavity and the connecting rod are mutually adapted, and the mounting cavity and the connecting rod form a locking structure.

[0012] The beneficial effects of this utility model are as follows: By providing a pushing mechanism on the lower inner side of the lower mold, the pusher plate can be driven to move upward by the cooperation between the fixed cavity, pusher plate, servo motor, threaded rod, threaded sleeve, movable cavity, limiting groove and limiting block of the pusher mechanism. The pusher plate pushes the pressed headlight lens and housing upward, making it easier and faster for the headlight lens and housing to be unloaded, avoiding the risk of damage from manual handling, simplifying operation and improving efficiency, thus greatly improving the working efficiency of the tooling. By providing a replacement mechanism on the lower part of the lower mold, the lower mold can be easily replaced by the cooperation between the mounting cavity, connecting rod and positioning pin of the replacement mechanism.

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a tooling for aligning and pressing a vehicle headlight lens and its housing. The tooling includes a base plate 1, a lower mold 2 mounted on the top of the base plate 1, a replacement mechanism located below the lower mold 2, a placement groove 3 inside the lower mold 2, a pushing mechanism inside the lower mold 2, a fixing rod 4 mounted at the rear end of the top of the base plate 1, a top plate 5 mounted on the top of the fixing rod 4, a hydraulic cylinder 6 mounted on the top of the top plate 5, the output end of the hydraulic cylinder 6 extending below the top plate 5, a fixing plate 7 mounted on the bottom end of the hydraulic cylinder 6, an mounting plate 8 mounted on the bottom end of the fixing plate 7, and a pressing head 9 mounted on the bottom end of the mounting plate 8. The mounting plate 8 and the pressing head 9 can be easily replaced using bolts.

[0020] The pushing mechanism includes a fixed cavity 13, a pushing plate 14, a servo motor 15, a threaded rod 16, a threaded sleeve 17, a movable cavity 18, and a limiting structure. The fixed cavity 13 is installed at the top of the base plate 1. The servo motor 15 is installed at the bottom of the fixed cavity 13. The threaded rod 16 is installed inside the fixed cavity 13. The output end of the servo motor 15 is connected to one end of the threaded rod 16. A threaded sleeve 17 is provided on the outer wall of the threaded rod 16. The movable cavity 18 is fixedly installed on the outer wall of the threaded sleeve 17. The pushing plate 14 is installed at the top of the movable cavity 18. The bottom of the placement groove 3 is provided with a clearance hole for avoiding the pushing plate 14. The limiting structure is used to limit the movement of the movable cavity 18. A sponge pad is provided above the pushing plate 14. The pad is used to protect the lens. When in use, the servo motor 15 is started to drive the threaded rod 16 to rotate, which in turn drives the threaded sleeve 17 to move. Under the limit of the limiting groove 19 and the limiting block 20, the threaded sleeve 17 drives the movable cavity 18 to move, which in turn drives the pusher plate 14 to move upward. The pusher plate 14 pushes the housing and lens upward, thus facilitating the unloading of the headlight lens and housing. Then, the servo motor 15 is started to drive the pusher plate 14 to return to its original position. The pusher plate 14 pushes the pressed headlight lens and housing upward, causing the headlight lens and housing to move upward. This makes the unloading of the headlight lens and housing more convenient and faster, avoiding the risk of damage from manual handling, simplifying operation, and improving efficiency, thereby greatly improving the working efficiency of the tooling.

[0021] The limiting structure includes a limiting groove 19 and a limiting block 20. The limiting groove 19 is formed on the inner wall of the fixed cavity 13. The limiting block 20 is provided inside the limiting groove 19. One end of the limiting block 20 is connected to the outer side of the movable cavity 18. The cross-section of the limiting groove 19 is larger than the cross-section of the limiting block 20. The limiting groove 19 and the limiting block 20 form a sliding structure. In use, the mutual cooperation between the limiting groove 19 and the limiting block 20 can limit the movement of the movable cavity 18, making the movable cavity 18 more stable when moving.

[0022] The replacement mechanism includes a mounting cavity 10, a connecting rod 11, and a positioning pin 12. The mounting cavity 10 is mounted on the top of the base plate 1. The connecting rod 11 is disposed inside the mounting cavity 10, and the top end of the connecting rod 11 is connected to the bottom end of the lower mold 2. The mounting cavity 10 and the side wall of the connecting rod 11 are provided with pin holes for installing the positioning pin 12 to fix the mounting cavity 10 and the connecting rod 11. The mounting cavity 10 and the connecting rod 11 are mutually compatible, forming a locking structure. When the lower mold 2 needs to be replaced, the positioning pin 12 is... Pull the connecting rod 11 out from the pin holes of the mounting cavity 10 and the connecting rod 11. At this time, the connecting rod 11 can be removed from the inside of the mounting cavity 10 to complete the disassembly of the lower mold 2. Then, take out the new lower mold 2 and place the connecting rod 11 into the inside of the mounting cavity 10. Use the positioning pin 12 to fix the position of the mounting cavity 10 and the connecting rod 11. The lower mold 2 can be easily replaced. At the same time, the mounting plate 8 and the pressing plastic head 9 can be easily disassembled and installed using bolts. This makes it more convenient and faster to process different models of car lights, thereby greatly improving the versatility of the tooling in use.

[0023] Working principle: The operator first places the lens into the housing, then into the placement groove 3. At this time, the hydraulic cylinder 6 is activated to move the pressing head 9 downward, using the pressing head 9 to press the lens and the housing together. After pressing, the hydraulic cylinder 6 is activated to move the pressing head 9 upward, and then the servo motor 15 is activated to rotate the threaded rod 16, which in turn moves the threaded sleeve 17. Therefore, under the limitation of the limiting groove 19 and the limiting block 20, the threaded sleeve 17 moves the movable cavity 18, which in turn moves the pusher plate 14 upward, using the pusher plate 14 to push the housing. The lens moves upward, allowing for easy unloading of the headlight lens and housing. Then, the servo motor 15 is activated to push the pusher plate 14 back to its original position. When the lower mold 2 needs to be replaced, the positioning pin 12 is pulled out from the mounting cavity 10 and the connecting rod 11. At this time, the connecting rod 11 can be removed from the mounting cavity 10, completing the disassembly of the lower mold 2. Then, the new lower mold 2 is removed, and the connecting rod 11 is placed into the mounting cavity 10. The positioning pin 12 is used to fix the position of the mounting cavity 10 and the connecting rod 11. Finally, the mounting plate 8 and the pressing plastic head 9 can be easily replaced using bolts.
