[0024] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] The present invention provides a processing device for the end slots of the thrust washer, such as... Figure 1-2 As shown, it includes a circular alignment body 2, one side of which has an alignment plane 19, and a frustum 16 is formed on the surface of the alignment body 2 along its circumference. The frustum 16 is located at the edge of the alignment body 2. The alignment body 2 is connected to a fancy pressure plate 3. The surface of the fancy pressure plate 3 is uniformly formed with a plurality of through grooves 22 along its circumference. The through grooves 22 pass through the edge of the fancy pressure plate 3. The frustum 16 forms a support surface 17 on the alignment body 2. The support surface 17 bears the force of the thrust washer 1. One side of the alignment body 2 is a mounting surface 18. The mounting surface 18 levels the support surface 17 in the horizontal direction. The mounting surface 18 is placed on the machine tool worktable. The inner hole 10 and any end face 11 of the thrust washer 1 are assembled with the support surface 17 on the frustum 16 to quickly achieve the first positioning of the thrust washer 1. The through-plate 3 is used to achieve clamping. The through groove 22 provides the tool feed path to the oil groove 9, i.e., an unobstructed passage. This assembly process eliminates the need to use a dial indicator to align the thrust washer 1 through automatic centering, thus solving the problem that existing machining methods require alignment for each part.

[0026] Example 1

[0027] like Figure 3-5 As shown, the surface of the alignment body 2 has two countersunk holes 15, which are located on the same straight line and are close to the frustum 16. After the alignment body 2 is placed on the machine tool table, the countersunk holes 15 are used to bury the through screw heads of the internal hexagon socket screws.

[0028] A threaded hole 13 is provided in the center of the surface of the alignment body 2. The threaded hole 13 and two countersunk holes 15 are arranged on the same straight line, with the two countersunk holes 15 located on both sides of the threaded hole 13. A through hole 20 is provided in the center of the fancy pressure plate 3. A screw 5 is connected between the through hole 20 and the threaded hole 13. Figure 6-7 As shown.

[0029] A washer 6 is fitted onto the screw 5. The alignment body 2 and the fancy pressure plate 3 are fastened together by the screw 5, thereby pressing the thrust washer 1.

[0030] Example 2

[0031] The surface of the alignment body 2 is provided with a first positioning hole 12 and a second positioning hole 14. The second positioning hole 14 is located near the alignment end face 19. The first positioning hole 12, the second positioning hole 14, and the threaded hole 13 are arranged on the same straight line. The first positioning hole 12 and the second positioning hole 14 are respectively located on both sides of the threaded hole 13. The straight line formed by the first positioning hole 12 and the second positioning hole 14 and the straight line formed by the two countersunk holes 15 are perpendicular to each other. A first positioning pin 4 is connected in the first positioning hole 12. The first positioning hole 12 plays a positioning role for the thrust washer 1, the second positioning hole 14 plays a circumferential limiting role for the fancy pressure plate 3, and the threaded hole 13 plays a centering role for the fancy pressure plate 3. By assembling the support surface 17 on the round platform, the first positioning pin 4 with the inner hole 10, end face 11 and positioning hole 8 of the thrust washer 1, the second positioning of the thrust washer 1 is quickly achieved. This assembly process eliminates the need to use a dial indicator to align the thrust washer 1 through automatic centering and positioning, and also improves the positional accuracy of the oil groove 9 on the thrust washer 1.

[0032] Example 3

[0033] The surface of the decorative pressure plate 3 is provided with a third positioning hole 21, which is arranged on the same straight line as the through hole 20. A second positioning pin 7 is connected between the third positioning hole 21 and the second positioning hole 14. The third positioning hole 21 and the second positioning hole 14 cooperate with each other, and the second positioning pin 7 is connected to provide circumferential positioning for the decorative pressure plate 3.

[0034] The operating procedure of the processing device for the holes and grooves at both ends of the thrust washer of the present invention is as follows:

[0035] Place the mounting surface 18 of the alignment body 2 on the machine tool worktable, making the alignment surface 19 parallel to the X-axis or Y-axis. Then, use an Allen screw to screw into a T-nut in the T-slot of the worktable through the countersunk hole 15 to secure the alignment body 2. Use the frustum 16 to determine the coordinate position of the rotation center of the alignment body 2 on the worktable, establishing the relative coordinate origin during machining. Fit the support surface 17 on the frustum 16 with the inner hole 10 and any end face 11 of the thrust washer 1. Figure 8-9As shown, the thrust washer 1 is fastened with the fancy pressure plate 3, and the mass production of the positioning holes 8 on the thrust washer 1 can begin. After all the positioning holes 8 on the thrust washer 1 are processed, the first positioning pin 4 is inserted into the first positioning hole 12, ensuring that the length of the exposed part of the first positioning pin 4 is less than the depth of the positioning hole 8 on the thrust washer 1 to prevent interference between the positioning of the end faces 11. The support surface 17 on the frustum 16, the first positioning pin 4, and the inner hole 10, end face 11, and positioning hole 8 of the thrust washer 1 are fitted together. The fancy pressure plate 3 is placed on the end face of the oil groove 9 to be processed on the thrust washer 1. The screw 5 with the washer 6 is passed through the through hole 20 on the fancy pressure plate 3 and screwed into the threaded hole 13 on the alignment body 2. The second positioning pin 7 is inserted into the third positioning hole 21 and the second positioning hole 14. Finally, the screw 5 is tightened, and the processing of the oil groove 9 on the thrust washer 1 can begin.

[0036] The processing device for the holes and grooves at both ends of the thrust washer of the present invention unfolds around the positioning hole 8 on the thrust washer 1, and completes the processing in sequence according to the processing order of "hole first, groove later", and uses the positioning groove 8 as the positioning reference when processing the oil groove 9.
