[0018] 2.

[0028] Please see Figures 1-5 This utility model provides a technical solution: a fixture for pin production, including a base 1, a fixture assembly 2 slidably connected to the top of the base 1, a wear-resistant mechanism 3 provided on the inner side of the fixture assembly 2, and a mounting mechanism 4 fixedly connected to the top of the fixture assembly 2. The wear-resistant mechanism 3 includes a mounting plate 31, a mounting hole 32, and a wear-resistant pad 33. The mounting plate 31 is located on the top of the fixture assembly 2, the mounting hole 32 is opened on the top of the mounting plate 31, and the wear-resistant pad 33 is fixedly connected to the bottom of the mounting plate 31. The inner side of the wear-resistant pad 33 is in contact with the outer side of the fixture assembly 2. The mounting mechanism 4 includes a motor 41, a shrink wheel 42, a transmission belt 43, a sliding column 44, a transmission plate 45, a return spring 46, a horizontal plate 47, a transmission wheel 48, and a pressure plate 49. The shrink wheel 42 is fixedly connected to the output end of the motor 41, and the transmission belt... 43 is connected to the surface of the retraction wheel 42. The transmission plate 45 is slidably connected to the surface of the slide column 44. The return spring 46 is sleeved on the surface of the slide column 44. The top of the return spring 46 is fixedly connected to the top of the transmission plate 45. The bottom of the horizontal plate 47 is fixedly connected to the top of the transmission plate 45. The transmission wheel 48 is fixedly connected to the outside of the horizontal plate 47 through a connecting rod. The side of the transmission belt 43 away from the retraction wheel 42 is connected to the transmission wheel 48. The front of the pressure plate 49 is fixedly connected to the back of the transmission plate 45. The bottom of the motor 41 is fixedly connected to the housing assembly 5. The inner wall of the housing assembly 5 is fixedly connected to both ends of the slide column 44. The two sides of the back of the horizontal plate 47 are fixedly connected to the slide rod assembly 6. The back of the slide rod assembly 6 is slidably connected to the limit slide rail 7. The back of the limit slide rail 7 is fixedly connected to the inner wall of the housing assembly 5.

[0029] In this embodiment, specifically, by setting up the wear-resistant mechanism 3 and the mounting mechanism 4, the phenomenon that traditional pin production fixtures, due to the lack of protective measures, are prone to causing wear on the pin surface due to excessive friction during the clamping operation is changed, which greatly affects the subsequent production and processing quality of the pin.

[0030] Example 2

[0031] A fixture for producing pins has reinforcing plates 8 fixedly connected to both sides of the outer shell assembly 5. The bottom of the reinforcing plates 8 is fixedly connected to the top of the fixture assembly 2. A limiting block 9 is fixedly connected to the top of the motor 41. The back of the limiting block 9 is fixedly connected to the inner wall of the outer shell assembly 5. A reinforcing block 10 is fixedly connected to the top of the horizontal plate 47. The bottom of the reinforcing block 10 is fixedly connected to the top of the transmission plate 45. A connecting plate 11 is fixedly connected to the top of the transmission plate 45. The bottom of the connecting plate 11 is fixedly connected to the top of the pressure plate 49.

[0032] In this embodiment, specifically: the reinforcing plate 8 strengthens the outer shell assembly 5, enhancing the connection between the outer shell assembly 5 and the clamp assembly 2, ensuring a more stable connection and preventing detachment during long-term use; the limiting block 9 reinforces and limits the motor 41, ensuring a more stable connection between the motor 41 and the outer shell assembly 5, preventing positional displacement of the motor 41 due to vibration or other factors, thus protecting the structural integrity; the reinforcing block 10 strengthens the horizontal plate 47, preventing breakage during long-term use and enhancing the connection with the transmission plate 45; and the connecting plate 11 reinforces the pressure plate 49, strengthening the connection between the pressure plate 49 and the transmission plate 45, ensuring a more stable connection.

[0033] Working principle: Simply place the mounting plate 31 on top of the fixture assembly 2, so that the wear-resistant pad 33 is in contact with the outer side of the fixture assembly 2, and then start the motor 41. The output end of the motor 41 drives the shrink wheel 42 to rotate. The shrink wheel 42 drives the transmission wheel 48 to move up and down through the transmission belt 43. The transmission wheel 48 drives the transmission plate 45 to move up and down through the horizontal plate 47. The transmission plate 45 drives the pressure plate 49 to move up and down until it is in contact with the top of the mounting plate 31, thereby achieving the effect of avoiding wear on the surface of the pin shaft due to the lack of protective measures in the pin shaft production fixture.
