[0002] A car is a vehicle that carries people and goods; it is a vehicle that tows people and goods. Car doors provide a passage for drivers and passengers to enter and exit the vehicle, and isolate external interference, thereby mitigating side impacts and protecting occupants to some extent.

[0003] Hinges are an essential component when installing car doors. They connect the door to the car body, ensuring and maintaining the door's position relative to the body, while also facilitating the opening and closing of the door.

[0004] The installation of hinges requires the use of an assembly machine. Since the assembly structure on the assembly machine is usually matched with the specifications of the hinge to be assembled, it is necessary to replace the hinge when changing the specifications. The existing assembly structure is fixed by bolts in multiple different positions, which is cumbersome and inconvenient to disassemble and replace, which is time-consuming and reduces work efficiency.

The snap-fit ​​blocks and the bidirectional screws form a lead screw drive. The bottom end of the mounting base is provided with a snap-fit ​​groove. The snap-fit ​​blocks are slidably inserted into the inner cavity of the snap-fit ​​groove. The cross-section of the snap-fit ​​blocks is L-shaped.

[0010] Preferably, the limiting mechanism includes: A limiting plate is provided, and the top of the worktable is symmetrically provided with limiting grooves.

By releasing the limiting mechanism from restricting the placement plate, the transmission mechanism can drive the placement plate to detach from the mounting frame. At this point, the placement plate can be rotated to directly replace the pre-installed assembly base of the next production specification in front. The transmission mechanism then resets the previous production specification assembly base, pushing it back to the rear of the mounting frame, allowing normal production to proceed. Simultaneously, the assembly base of the next production specification can be disassembled and assembled via the installation mechanism, enabling rapid switching of assembly bases. This allows the production line to quickly respond to changes in production plans, achieving flexible production of small batches and multiple varieties. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0018] This utility model provides, for example Figures 1-3 The illustrated automotive component hinge assembly device includes a worktable 1, an assembly mechanism 3, a placement plate 4, an assembly base 5, a transmission mechanism 6, a mounting mechanism 7, and a limiting mechanism 8. A mounting bracket 2 is fixedly connected to the top of the worktable 1. The assembly mechanism 3 is mounted on the mounting bracket 2. The placement plate 4 is slidably inserted into the inner cavity of the mounting bracket 2. The assembly base 5 is symmetrically arranged on the placement plate 4. The transmission mechanism 6 is located inside the worktable 1 and is used to drive the placement plate 4 to move. The mounting mechanism 7 is located inside the placement plate 4 and is used to position the assembly base 5. The limiting mechanism 8 is located inside the worktable 1. The limit mechanism 8 is used to limit the displacement of the placement plate 4. By releasing the limit mechanism 8 on the placement plate 4, the transmission mechanism 6 can drive the placement plate 4 to disengage from the limit of the mounting frame 2. At this time, the placement plate 4 can be rotated to directly replace the pre-installed assembly base 5 of the next production specification to the front, and reset through the transmission mechanism 6. The assembly base 5 of the previous production specification is pushed back to the rear of the mounting frame 2, and production can proceed normally. At the same time, the assembly base 5 of the next production specification can be disassembled and assembled through the mounting mechanism 7, realizing the switching of the assembly base 5 in a short time.

[0019] Specifically, the assembly mechanism 3 includes a cylinder 31, a transmission plate 32, and an assembly block 33. The cylinder 31 is fixedly installed on the top of the mounting bracket 2, and the output end of the cylinder 31 is connected to the transmission plate 32. The assembly block 33 is fixedly installed on the bottom of the transmission plate 32. The cylinder 31 serves as a power source, pushing the transmission plate 32 and the assembly block 33 at its bottom to move downwards, thereby performing assembly and pressing operations on the hinge placed on the assembly base 5.

[0020] Specifically, the transmission mechanism 6 includes a slide rod 61, a slide table 62, and an electric telescopic rod 63. The top of the worktable 1 has a groove. The end of the slide rod 61 is fixedly connected to the inner wall of the groove. The slide table 62 is slidably inserted and connected to the slide rod 61. The placement plate 4 is rotatably set on the top of the slide table 62. The electric telescopic rod 63 is fixedly installed inside the worktable 1. The output end of the electric telescopic rod 63 is connected to the slide table 62. When the electric telescopic rod 63 extends and retracts, it pushes the slide table 62 to slide precisely along the slide rod 61, thereby driving the entire placement plate 4 and the assembly base 5 on it to move into or out of the working position. Thus, it can get rid of the limitation of the mounting frame 2 when it is pushed out. At the same time, after the limitation of the limiting mechanism 8 is released, the placement plate 4 can be rotated to realize the rapid switching of assembly bases 5 of different specifications.

[0021] Specifically, the mounting mechanism 7 includes a bidirectional screw 71 and a locking block 72. The top of the placement plate 4 has a mounting groove. The end of the bidirectional screw 71 is rotatably inserted into the inner wall of the mounting groove. The locking blocks 72 are symmetrically arranged inside the mounting groove. The locking blocks 72 and the bidirectional screw 71 form a screw drive. The bottom of the assembly base 5 has a locking groove. The locking blocks 72 are slidably inserted into the inner cavity of the locking groove. The cross section of the locking blocks 72 is L-shaped. Rotating the bidirectional screw 71 drives the two L-shaped locking blocks 72 to move synchronously towards or away from each other, thereby locking or releasing the assembly base 5 from the bottom. This realizes the quick connection between the assembly base 5 and the placement plate 4 and also facilitates the replacement of the assembly base 5 at any time.

[0022] Specifically, the limiting mechanism 8 includes a limiting plate 81, a synchronization plate 82, and a compression spring 83. The top of the worktable 1 has symmetrically arranged limiting grooves. The limiting plate 81 is slidably inserted into the inner cavity of the limiting groove. The outer wall of the worktable 1 has a pull groove communicating with the limiting groove. The synchronization plate 82 passes through the pull groove and is fixedly connected to the limiting plate 81. The bottom end of the inner wall of the limiting groove has an elastic groove. The compression spring 83 is located inside the elastic groove. One end of the compression spring 83 is fixedly connected to the limiting plate 81, and the other end is fixedly connected to the bottom end of the inner wall of the elastic groove. Under the thrust of the compression spring 83, the limiting plate 81 pops upward, locking the placement plate 4 so that it cannot move. When a change of shape is needed, the synchronization plate 82 can be manually pulled downward to release the limiting mechanism. At the same time, the limiting plate 81 can also act as a limiting mechanism, allowing the placement plate 4 to be accurately inserted into the inner cavity of the mounting frame 2 after the electric telescopic rod 63 drives the slide table 62 to move, facilitating its use.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
