[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] This specific embodiment provides a processing device for knurling pins, which solves the technical problems of existing knurling machines being unable to process high-precision parts and small batches of parts.

[0023] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures represented in the following embodiments are not limited to those necessary for the solution of the utility model as described in the claims.

[0024] Reference Figures 1-3 This utility model provides a processing device for knurling pins, including a base 1, a first positioning base 2, a second positioning base 3, a power source, and a knurling cutter 4. The first positioning base 2 and the second positioning base 3 are fixedly installed on the base 1, ensuring a certain distance between them. To place the workpiece to be processed, a stepped surface 21 is provided on the side of the first positioning base 2 closest to the second positioning base 3, and the workpiece is placed on the stepped surface 21. To facilitate positioning the knurling position of the workpiece, a positioning component is provided at one end of the stepped surface 21. To facilitate the knurling of the cutter 4, a first groove penetrating vertically is provided on the side of the first positioning base 2 closest to the second positioning base 3. The depth of the first groove is greater than the depth of the stepped surface, thus facilitating the rotation of the workpiece. The knurling cutter 4 is movably installed on the second positioning base 3. The power source is installed above the knurling cutter 4 to drive it to move up and down. Specifically, a support frame is provided to support the power source, which facilitates its fixation.

[0025] This setup, with its positioning components, precisely determines the location to be processed. It also ensures structural stability and reliability, simplifies operation, improves worker efficiency, and reduces costs. The knurling structure utilizes high-strength metal processing to meet various knurling requirements.

[0026] To further optimize the design, in order to facilitate the positioning component 5 in defining different workpieces to be processed, the positioning component 5 includes a positioning seat 51, an adjusting bolt 52, and a positioning block 53. The positioning seat 51 is detachably mounted on the first positioning base 2. A positioning groove 511 is provided on the positioning seat 51. The positioning block 53 is installed in the positioning groove 511. The adjusting bolt 52 passes through the side wall of the positioning groove 511 and connects with the positioning block 53 to drive the positioning block 53 to move, thereby adjusting the position of the workpiece to be processed. Specifically, the adjusting bolt 52 and the positioning block 53 are rotatably connected, so that the positioning block 53 can move along the length of the positioning groove 511.

[0027] To further optimize the design, in order to facilitate the positioning block 53, a second dovetail groove and a second protrusion are provided between the positioning block 53 and the positioning groove 511. The second protrusion can be set on the positioning block 53, and the positioning groove 511 can be set on the side wall of the positioning groove 511. The second protrusion is inserted into the second dovetail groove. This arrangement allows the second protrusion to move along the extension direction of the second dovetail groove, ensuring that the positioning block 53 moves linearly.

[0028] To further optimize the design and ensure that the positioning seat 51 can be installed on the first positioning base 2, a third dovetail groove and a third protrusion are provided between the positioning seat 51 and the first positioning base 2. The third protrusion is installed on the positioning seat 51, and the third dovetail groove is installed on the first positioning base 2. Figure 1 It can be seen that the shape of the third protrusion is the same as that of the third dovetail groove, which makes it convenient for the third protrusion to be inserted into the third dovetail groove, while ensuring the tightness of the connection between the two.

[0029] To further optimize the design, in order to ensure that the workpiece can be stably installed on the step surface 21, the horizontal plane of the step surface 21 is set as an inclined plane. This way, the workpiece can be prevented from moving outward under its own weight.

[0030] To further optimize the design, in order to ensure that the knurling cutter 4 can move straight up and down, the second positioning base 3 is provided with a first dovetail groove 31 on the side close to the first positioning base 2, and the knurling cutter 4 is provided with a first protrusion 41 that cooperates with the first dovetail groove 31. The first protrusion 41 is located in the first dovetail groove 31. The cooperation between the first protrusion 41 and the first dovetail groove 31 can play a guiding role, so that the knurling cutter 4 can move in a straight line. Specifically, the side of the knurling cutter 4 away from the second positioning base 3 is provided with knurling teeth, which are evenly distributed along the height direction of the knurling cutter.

[0031] To further optimize the design, in order to extend the length of the knurling cutter 4's movement, a second through hole 11 is provided on the base 1. The knurling cutter 4 passes through the second through hole 11, so that when processing a relatively rough workpiece, the knurling cutter 4 can pass through the second through hole 11 and continue to move downwards.

[0032] To further optimize the design, in order for the positioning block 53 to move along the step surface 21, the vertical surface of the positioning groove 511 is flush with the vertical surface of the step surface 21, and the horizontal surface of the positioning groove 511 is flush with the horizontal surface of the step surface 21. This allows the positioning block 53 to move along the step surface 21.
