[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example 1, as Figure 1-4As shown, this utility model provides a technical solution: a lathe fixture for processing drive end caps, including a round aluminum base 1, a slide rail 5, and a cross slot block 6. The top of the round aluminum base 1 is provided with the slide rail 5, and the bottom of the slide rail 5 is provided with the cross slot block 6. A slider 8 is provided inside the slide rail 5, and a rotating shaft 9 is mounted on the top of the slider 8 through a bearing. A positioning plate 7 is mounted on the top of the rotating shaft 9, and a positioning ball 701 is provided at the bottom of the positioning plate 7 that contacts the top of the round aluminum base 1. An arc-shaped groove is provided inside the slide rail 5, and a transmission ball that contacts the slider 8 is provided inside the arc-shaped groove. By placing the drive end cap body 4 above the round aluminum base 1, and then releasing the limiting mechanism and tightening it, the positioning plate 7 rotates through the rotating shaft 9, thereby driving the hydraulic lifting rod 3 to adjust the pressing angle, which facilitates movement at different angle positions. In addition, the positioning block 301 can slide at the output end of the hydraulic lifting rod 3 to meet the pressing requirements at different angles.

[0015] Example 2, as Figure 1-5 As shown, this utility model provides a technical solution: a lathe fixture for processing drive end caps, including a positioning plate 7 with a limiting mechanism for positioning inside, a hydraulic lifting rod 3 above the positioning plate 7, and a positioning block 301 for pressing at the output end of the hydraulic lifting rod 3, a drive end cap body 4 placed at the center position above the circular aluminum base 1, a positioning plate 2 placed at the top of the drive end cap body 4, and a positioning pin 201 for positioning the drive end cap body 4 installed at the bottom end of the positioning plate 2, the limiting mechanism including an insert rod 10 and a pull rod 11, and through holes opened at the slider 8 and the rotating shaft 9. A cross groove is provided on one side of the positioning plate 7, and a through hole is provided inside the cross groove, extending into the cross slot block 6. A pull rod 11 is installed at the top of the pull rod 10, and a compression block adapted to the cross groove is installed on the outer wall of the pull rod 11. A spring 12 is sleeved on the outer wall of the pull rod 10, and the outer wall of the spring 12 is in contact with the compression block. By pulling the pull rod 11, the lower part of the pull rod 10 is not in contact with the cross slot block 6, so that the positioning plate 7 can slide freely in the slide rail 5 through the slider 8, which can meet the multi-directional adjustment, improve flexibility, enhance adaptability, and reduce cost investment.

[0016] Working principle: First, connect the external power supply. Then, place the drive end cover body 4 above the round aluminum base 1. Next, the positioning plate 2 drives the positioning pin 201 to insert into the position above the drive end cover body 4. Then, the rotatable positioning block 301 is adjusted to a suitable pressing position. The hydraulic lifting rod 3 is started to drive the positioning block 301 to press on the outside of the positioning plate 2. At this time, the three sets of hydraulic lifting rods 3 and positioning blocks 301 can meet the pressing stability and improve the working efficiency during processing. When it is necessary to rotate the positioning plate 7 to adjust the angle of the hydraulic lifting rod 3, and then adjust the front and rear contact positions of the drive end cover body 4 to meet the requirements of pressing different front and rear lengths of the drive end cover body 4, the lower part of the insertion rod 10 can be moved away from contact with the cross slot block 6 by pulling the pull rod 11. Then, the positioning plate 7 rotates through the rotating shaft 9 to adjust the contact position between the hydraulic lifting rod 3 and the drive end cover body 4. In addition, the positioning plate 7 can slide freely in the slide rail 5 through the slider 8, which can meet the adjustment in multiple directions, improve flexibility, enhance adaptability, and reduce cost investment.
