[0002] A gear is a mechanical component with teeth on its rim that continuously meshes to transmit motion and power. During gear processing, the inner wall of the gear needs to be ground. For example, patent application number CN202321213783.2 describes a gear deburring and grinding device, including a machine base mounted on a processing platform. The machine base contains a drive mechanism, the output end of which penetrates the side wall of the machine base. The device is characterized by a fixed shaft on the output end of the drive mechanism, a mounting base on the fixed shaft, and an internal support chuck on the mounting base. This utility model relates to the technical field of... In this method, the gear is inserted into the inner support chuck, and the movement of the inner support chuck is controlled to clamp and fix the gear at the center hole position. After fixing, the movement adjustment parts on both sides of the fixing bracket are controlled to move the grinding head in the horizontal direction, so that the grinding head is closer to the gear. After it is close, the position of the grinding head is finely adjusted by the swing adjustment part, so that the grinding head contacts the gear more closely to the gear end face. In the above technical solution, it is not easy to fix gears of different specifications, and the position of the grinding head is not easy to adjust, which is inconvenient for grinding gears of different specifications.

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1 As shown, a gear center hole grinding device includes a processing table 1. The upper surface of the processing table 1 is provided with a mounting groove 2. A fixing ring 4 is provided inside the mounting groove 2. A plurality of gear teeth 3 are equidistantly arranged on the inner wall of the fixing ring 4. A mounting rod 5 is fixedly installed on the upper surface of the processing table 1. A top plate 6 is fixedly installed at the top end of the mounting rod 5. A drive adjustment component 7 is provided on the top plate 6. A second servo motor 8 is installed on the drive adjustment component 7. A grinding drill bit 9 is installed at the output end of the second servo motor 8.

[0020] like Figure 2 , 3 As shown in Figure 4, a plurality of positioning holes 10 are equidistantly opened on the inner surface of the mounting groove 2, and a plurality of positioning posts 11 are equidistantly installed on the lower surface of the fixing ring 4. The positioning posts 11 are set inside the positioning holes 10. By setting the positioning posts 11 inside the positioning holes 10, the fixing ring 4 can be set inside the mounting groove 2, thus ensuring the stability of the fixing ring 4.

[0021] like Figure 2As shown, the drive adjustment assembly 7 includes a first hydraulic cylinder 701, which is fixedly mounted on the lower surface of the top plate 6. A fixed plate 702 is fixedly mounted on the output end of the first hydraulic cylinder 701. A first servo motor 703 is fixedly mounted on the lower surface of the fixed plate 702. A turntable 705 is mounted on the output end of the first servo motor 703. Connecting rods 704 are fixedly mounted at equal intervals on the lower surface of the turntable 705. A limiting plate 709 is fixedly mounted on the lower surface of the connecting rods 704. A guide groove 707 is formed through the surface of the limiting plate 709. A guide block 708 is slidably mounted in the middle of the guide groove 707. A second servo motor 708 is fixedly mounted on the guide block 708. At the lower end of 08, a second hydraulic cylinder 706 is fixedly installed on the upper surface of the limiting plate 709. The output end of the second hydraulic cylinder 706 is located on one side surface of the guide block 708. The first hydraulic cylinder 701 extends and retracts, driving the limiting plate 709 downwards, thus moving the grinding drill bit 9 downwards. The second hydraulic cylinder 706 then extends and retracts, driving the guide block 708 to slide inside the guide groove 707, thus moving the grinding drill bit 9 and placing it against the inner wall of the gear. The first servo motor 703 then drives the turntable 705 to rotate, which in turn drives the limiting plate 709 to rotate. This allows adjustment of the position of the grinding drill bit 9, enabling it to grind the inner wall of the gear. This device can fix gears of different specifications and can adjust the position of the grinding drill bit 9 according to the gear's specifications to grind the inner wall of different gears.

[0022] Working principle of this gear center hole grinding device:

[0023] In use, when grinding the center hole of the gear is required, first, a retaining ring 4 of appropriate size is placed inside the mounting groove 2, so that several gear teeth 3 mesh with the gear that can be machined. At this time, the gear is placed inside the mounting groove 2, so that the gear meshes with several gear teeth 3, which plays a role in fixing the gear. At this time, the output end of the first hydraulic cylinder 701 extends and retracts, which drives the limiting plate 709 to move downward, so that the grinding drill bit 9 moves downward. At this time, the output end of the second hydraulic cylinder 706 extends and retracts, which drives the guide block 708 to slide inside the guide groove 707, which drives the grinding drill bit 9 to move and put the grinding drill bit 9 against the inner wall of the gear. At this time, the output end of the first servo motor 703 drives the turntable 705 to rotate, which drives the limiting plate 709 to rotate. The position of the grinding drill bit 9 can be adjusted, allowing the grinding drill bit 9 to grind the inner wall of the gear. This device can fix gears of different specifications and can also adjust the position of the grinding drill bit 9 according to the specifications of the gear to grind the inner wall of different gears.
