DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0014] Please refer to Figures 1-4, the present utility model provides a technical solution: an engine piston pin stamping device, including a base 1. The center of the top of the base 1 is fixedly connected with a die base 7. The center of the top of the die base 7 is fixedly installed with a placement seat 9. A placement groove 10 is opened at the center of the top of the placement seat 9. A workpiece body 11 is placed inside the placement groove 10. Activity grooves 12 are opened on both sides of the placement seat 9 corresponding to the placement groove 10. A clamping plate 14 is slidably connected inside the activity groove 12. One side of the clamping plate 14 penetrates to the inside of the placement groove 10 and contacts the surface of the workpiece body 11. Miniature cylinders 18 are fixedly installed at both sides of the placement seat 9. The output end of one side of the miniature cylinder 18 is fixedly connected with a piston rod 19. One side of the piston rod 19 is fixedly connected with a connecting rod 20. One side of the connecting rod 20 is fixedly connected with a support plate 16. One side of the support plate 16 is fixedly connected with a reinforcing rod 17. One side of the reinforcing rod 17 is fixedly connected with the other side of the clamping plate 14.

[0015] Four sides of the top of the base 1 are all fixedly installed with side columns 2. The tops of the four side columns 2 are fixedly connected with a top plate 3. An activity plate 4 is slidably connected at the top position among the four side columns 2. The center of the bottom of the activity plate 4 is fixedly installed with a stamping seat 6.

[0016] The center of the top of the top plate 3 is fixedly installed with a stamping cylinder 5. The output end of the bottom of the stamping cylinder 5 penetrates to the outside of the top plate 3 and is fixedly connected with the top of the activity plate 4.

[0017] Limit sliding grooves 13 are opened at the top and bottom of the placement seat 9 corresponding to the activity grooves 12. The top and bottom of the support plate 16 respectively penetrate into the two limit sliding grooves 13 and are slidably connected with the limit sliding grooves 13. One side of the top and bottom of the clamping plate 14 is fixedly connected with a limit sliding block 15. The side of the limit sliding block 15 away from the clamping plate 14 penetrates to the inside of the limit sliding groove 13 and is slidably connected with the limit sliding groove 13, ensuring that the clamping plate 14 moves along a predetermined track under the drive of the miniature cylinder 18, thereby clamping the workpiece body 11 more stably and accurately, and improving the clamping accuracy and stability.

[0018] Damping rods 21 are fixedly connected at the top and bottom positions on the other side of the support plate 16. One side of the damping rod 21 is fixedly connected with the inner wall of the activity groove 12, which helps to reduce the shaking or vibration of the support plate 16 and the clamping plate 14 when clamping or releasing the workpiece body 11, and further improves the clamping stability and operation accuracy.

[0019] An anti-slip heat-insulating pad 23 is fixedly connected to the inner wall of the clamping plate 14. The inner wall of the anti-slip heat-insulating pad 23 is closely attached to the surface of the workpiece body 11, which not only increases the friction during clamping, prevents the workpiece body 11 from sliding during the stamping process, but also has a certain heat-insulating effect, reducing the damage to the workpiece body 11 or the clamping plate 14 caused by the high temperature generated during the stamping process.

[0020] A receiving groove 8 is provided near the bottom of the die base 7, and a leakage channel 22 is provided inside the placement seat 9 at the center of the bottom of the placement groove 10. The bottom of the leakage channel 22 penetrates into the receiving groove 8, which facilitates the waste or impurities generated during the stamping process to fall directly into the receiving groove 8 through the leakage channel 22, thereby simplifying the cleaning work and improving work efficiency.

[0021] Working principle: The workpiece body 11 is placed in the placement groove 10 on the top of the placement seat 9, and the micro cylinder 18 starts to work, pushing the connecting rod 20 to move through the piston rod 19. The movement of the connecting rod 20 drives the support plate 16 to slide in the limiting slide groove 13. The sliding of the support plate 16 drives the clamping plate 14 to slide in the movable groove 12 through the reinforcement rod 17 until one side of the clamping plate 14 contacts and clamps the surface of the workpiece body 11. The limiting slider 15 ensures that the clamping plate 14 moves along the predetermined trajectory, which improves the clamping accuracy and stability. The damping rod 21 is used when clamping or releasing the workpiece body 11. , reducing the shaking or vibration of the support plate 16 and the clamping plate 14, the anti-slip and heat-insulating pad 23 increases the friction during clamping to prevent the workpiece from sliding during the stamping process, and the stamping cylinder 5 starts to work, and the output end at its bottom pushes the movable plate 4 to slide down along the side column 2. The sliding of the movable plate 4 drives the stamping seat 6 at the bottom to move downward until the stamping seat 6 contacts the workpiece body 11 and performs stamping. During the stamping process, the waste or impurities generated fall directly into the impurity receiving groove 8 in the die base 7 through the impurity leakage channel 22 inside the placement seat 9. The design of the impurity receiving groove 8 simplifies the cleaning work and improves work efficiency.

[0022] To sum up: the engine piston pin stamping device, through the use of a clamping plate 14 system driven by a micro cylinder 18, can automatically adapt to workpiece bodies 11 of different sizes. The micro cylinder 18 is connected to the support plate 16 and the reinforcement rod 17 through the piston rod 19 and the connecting rod 20, thereby driving the clamping plate 14 to slide along the movable groove 12 to achieve clamping of workpieces of different sizes, solving the problem that the traditional single fixed groove is difficult to adapt to workpieces of different sizes. The structural design of the limiting slide groove 13 and the limiting slider 15 ensures that the clamping plate 14 moves along a predetermined trajectory under the drive of the micro cylinder 18. This design not only improves the clamping accuracy, but also enhances the clamping stability, thereby avoiding the displacement of the workpiece during the stamping process and ensuring the stamping accuracy and efficiency.
