[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Reference Figure 1-5A stamping device for automotive parts with different sizes is applicable to processing. It includes a stamping machine body 1, the stamping machine body 1 includes a worktable, a base 2 is provided at the top of the worktable, a support platform 21 is fixedly installed at the middle of the top of the base 2, and clamping components 3 are symmetrically arranged on both sides of the support platform 21 at the top of the base 2. It is worth noting that the specific structure, connection method and working principle of the punching machine body 1 and the worktable are all based on the "punching machine" already publicly available on the market, so they will not be described in detail.

[0015] The clamping assembly 3 includes a support 31, a screw assembly 32 is internally threaded to the support 31, and the end of the screw assembly 32 is movably connected to the movable clamping block 33 through a bearing. The clamping surface of the movable clamping block 33 is provided with a plurality of detachable auxiliary pressing components 34 at equal intervals. The auxiliary pressing component 34 includes a movable rod 341. One end of the movable rod 341 is rotatably connected to a movable pressing block 344 via a pin, and the other end of the movable rod 341 is fixedly installed with a limit ring 345. The limit ring 345 is slidably disposed in the movable clamping block 33, and a sliding cavity for the limit ring 345 to slide is opened in the movable clamping block 33. A spring body 343 is disposed in the sliding cavity. A connecting piece 342 is slidably sleeved on the outer wall of the movable rod 341, and the connecting piece 342 is threadedly connected to the movable clamping block 33. The connector 342 is T-shaped, and the outer wall of the connector 342 adjacent to the limiting ring 345 is provided with an external thread.

[0016] The movable clamping block 33 has a mounting groove on its clamping surface at the corresponding connector 342, and the inner wall of the mounting groove has an internal thread at the external threaded part, which is threadedly connected to the external threaded part. A flexible rubber pad is provided on one side of the clamping surface of the movable pressing block 344.

[0017] A scale line 4 is provided on one side of the top of the base 2, and the middle of the scale line 4 is the 0 point, which is located at the center of the support platform 21. A guide block 35 is provided on the side of the movable clamping block 33 adjacent to the scale line 4, and the tip of the guide block 35 points to the scale line.

[0018] Meanwhile, it is worth noting that a telescopic dust cover is provided on the outside of the screw assembly 32 and between the support 31 and the movable clamping block 33, and the spring body 343 is equipped with a damping component (the figure is only a simplified schematic diagram and the matching damping component is not shown). The specific structure and working principle of the screw assembly 32 and the spring body 343 are all existing technologies that are currently publicly available on the market, so they will not be described in detail.

[0019] When the movable clamping block 33 and the corresponding auxiliary pressing component 34 are moved toward the outer wall of the automotive part by rotating the screw assembly 32, the movable pressing block 344 first contacts the surface of the automotive part. As the movable clamping block 33 continues to move toward the automotive part, the movable pressing block 344 is pushed by a reverse force to move its movable rod 341 toward the movable clamping block 33 and compress the spring body 343. When both clamping components prevent the screw assembly 32 from rotating further (ensuring that the spring body 343 is compressed to provide sufficient clamping force), the clamping of the automotive part is completed, and the stability of the subsequent stamping process of the stamping press body 1 on the automotive part is ensured.

[0020] Some of the outer surfaces of the automotive parts have different undulations. When the movable pressing block 344 moves toward and fits the surface of the automotive parts, it can adaptively make a slight turn to ensure that its flexible rubber pad fits the surface of the automotive parts better. In addition, the setting of multiple sets of auxiliary pressing components 34 can avoid stress concentration points during the clamping process of the automotive parts.

[0021] In this embodiment, the automotive parts to be processed are placed on the support platform, and the screw assemblies 32 on both sides of the support platform 21 are rotated in sequence. By rotating the screw assemblies 32, the movable clamping block 33 and the corresponding auxiliary pressing assembly 34 are moved toward the outer wall of the automotive parts until they are completely pressed and adhered.

[0022] Then, observe the values ​​pointed to by the pointing blocks 35 of the two sets of movable clamping blocks 33, and make fine adjustments to the two sets of movable clamping blocks 33 to ensure that the values ​​pointed to by the pointing blocks 35 of the two sets of movable clamping blocks 33 are consistent. At this time, the center of the car part is aligned with the center of its support platform 21, and then the car part can be stamped by the stamping machine body 1.

[0023] Meanwhile, the auxiliary pressing component 34 is detachable. When any set of auxiliary pressing components 34 is worn or requires maintenance, the connecting piece 342 can be loosened and removed, and the internal spring body 343 can be maintained.

[0024] In this invention, the use of two sets of clamping components 3 and scale lines 4 facilitates the clamping of automotive parts of different sizes within a certain range, ensuring that the center of the automotive parts is aligned with the center of the support platform 21. This also ensures the stability of the stamping process of the stamping machine body 1 on the automotive parts. Furthermore, the use of multiple detachable auxiliary pressure components 34 helps to avoid stress concentration points during the clamping process of the automotive parts.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
