[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figures 1-4 As shown, an automotive button assembly fixture includes a fixture platform 1, a support frame 101, an electric cylinder 102, and a top cover pressing head 103. The support frame 101 is fixedly installed on the top of the fixture platform 1, and the electric cylinder 102 is installed on the top of the support frame 101. The output end of the electric cylinder 102 extends through the inner side of the support frame 101. The top cover pressing head 103 is installed at the output end of the bottom of the electric cylinder 102. An automatic clamping mechanism is provided inside the fixture platform 1. The automatic clamping mechanism includes a compression spring 201, a base 202, a connecting rod 203, a clamping head 204, and a limiting plate 205. One end of the compression spring 201 is fixedly connected to... At the bottom of the inner wall of the fixture table 1, the base 202 is fixedly connected to the other end of the compression spring 201. One end of each of the two connecting rods 203 is connected to both sides of the base 202 via a pivot, and the other ends of the two connecting rods 203 extend to the top of the fixture table 1. Two clamping heads 204 are respectively connected to the top of the connecting rods 203 via pivots. Both clamping heads 204 are located at the top of the fixture table 1. A limiting plate 205 is fixedly connected to the top of the fixture table 1. The limiting plate 205 is located on the front and rear sides of the two clamping heads 204, respectively. When assembling the button, the base plate can be placed on the two clamping heads 204 on the base 202 first. Then, the top cover is installed below the top cover pressure head 103. The electric cylinder 102 is then operated to push the top cover pressure head 103 downwards. The downward movement of the top cover pressure head 103 causes the top cover to move downwards and press down to engage with the vertically aligned base plate. During this downward pressing process, the base 202 is simultaneously pushed downwards. As the base 202 moves downwards, it compresses the compression spring 201. Simultaneously, the downward movement of the base 202 causes the bottom ends of the two connecting rods 203 to rotate slightly outwards, and the top ends of the two connecting rods 203 to rotate slightly inwards. When the top ends of the connecting rods 203 rotate slightly inwards... When activated, the two clamping heads 204 move inward simultaneously under the limit of the limiting plate 205. When the two clamping heads 204 move inward simultaneously, they can automatically squeeze and limit the button in the middle. After the button is assembled, the output end of the electric cylinder 102 is lifted upward. Under the elastic force of the compression spring 201, it will push the base 202 upward and reverse the above steps, so that the two clamping heads 204 no longer clamp and limit the button. This can automatically clamp the assembled button, reduce the repeated clamping and disassembly operations of the workers, and enable the button to be assembled quickly and accurately, thereby improving the overall production efficiency.

[0022] like Figure 3As shown, a protrusion 301 is fixedly connected to the inner side of the limiting plate 205. The front and rear sides of the two clamping heads 204 are provided with limiting grooves 302 that cooperate with the protrusion 301. When the clamping head 204 moves, the clamping head 204 can drive the protrusion 301 to slide under the limiting of the limiting groove 302. At the same time, under the auxiliary guidance of the limiting groove 302, the clamping head 204 moves in parallel, preventing the connecting rod 203 from driving the clamping head 204 to lift up on both sides when moving, which would affect the clamping and limiting of the button.

[0023] like Figures 1-2 As shown, a circular block 4 is fixedly connected to the bottom of the base 202. The circular block 4 is located between the base 202 and the clamping head 204. The circular block 4 can reduce the distance between the button base plate and the clamping head 204, and under the action of the circular block 4, the base plate can be raised. During the process of pressing down to assemble the button, the clamping head 204 can still stably clamp the button, preventing it from slipping away from the clamping limit of the clamping head 204 when pressing down to assemble the button.

[0024] like Figure 2 and 4 As shown, the top of the fixture table 1 is provided with a slot 5. The round block 4 and the connecting rod 203 are both located inside the slot 5. When the base 202 is pushed up and down, it will also drive the round block 4 and the connecting rod 203 to move, and make the round block 4 and the connecting rod 203 move flexibly inside the slot 5, so as to prevent them from colliding with the fixture table 1 during movement and affecting the normal operation of the automatic clamping mechanism.

[0025] like Figure 3 As shown, both clamping heads 204 have arc-shaped grooves 6 on their inner sides. The inner wall of the arc-shaped grooves 6 is connected to a protective layer. Under the action of the arc-shaped grooves 6, the contact area between the circular button and the clamping head 204 can be increased, thereby enabling stable clamping of the button. At the same time, under the action of the protective layer, the clamping head 204 can prevent scratching the surface of the button during the pressing and assembly process.

[0026] like Figure 4 As shown, a square hole 701 is provided at the bottom of the fixture table 1. A square rod 702 is fixedly connected to the bottom of the base 202. The other end of the square rod 702 passes through the square hole 701 and extends to the bottom of the fixture table 1. The square rod 702 is slidably connected inside the square hole 701. When the base 202 is pressed down, the base 202 will drive the square rod 702 to move downward and slide inside the square hole 701. Thus, with the guidance and assistance of the square rod 702 and the square groove, the base 202 can move vertically up and down, avoiding shaking when the base 202 and the compression spring 201 are pressed down.

[0027] The working principle of this utility model is as follows: When assembling the button, the base plate can be placed between the two clamping heads 204 on the base 202. Then, the top cover is installed below the top cover pressing head 103. Subsequently, the electric cylinder 102 is operated to push the top cover pressing head 103 downward. The downward movement of the top cover pressing head 103 will cause the top cover to move downward and press down to engage with the vertically aligned base plate. During the downward pressing process, the base 202 is also pushed downward. As the base 202 moves downward, it will compress the compression spring 201. At the same time, when the base 202 moves downward, it will cause the bottom ends of the two connecting rods 203 to rotate slightly outward, and simultaneously cause the top ends of the two connecting rods 203 to move upward. When the connecting rod 203 rotates slightly inward, it will simultaneously drive the two clamping heads 204 to move inward under the limit of the limiting plate 205. When the two clamping heads 204 move inward at the same time, they can automatically squeeze and limit the button in the middle. After the button is assembled, the output end of the electric cylinder 102 is lifted upward. Under the elastic force of the compression spring 201, it will push the base 202 upward and reverse the above steps, so that the two clamping heads 204 no longer clamp and limit the button. This can automatically clamp the assembled button, reduce the repeated clamping and disassembly operations of the workers, and enable the button to be assembled quickly and accurately, thereby improving the overall production efficiency.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
