Through the moving motor and the grinding motor, the grinding stones can be driven to move and rotate rapidly in a straight line, thereby enabling rapid grinding of both the inner and outer surfaces of the bearing seat blank, improving the deburring effect.

[0004] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation: after the bearing housing casting is produced, the burrs on its outer side need to be cleaned. When cleaning the burrs, the bearing housing casting needs to be fixed. Existing burr removal devices for bearing housing castings are not convenient for fixing bearing housing castings of different sizes, and the fixing process is relatively cumbersome.

[0024] 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.

[0025] Example 1: Please refer to Figure 1 - Figure 6 This utility model provides the following technical solution: a burr removal device for processing impact-resistant bearing seat castings, comprising a base plate 1, with two symmetrically distributed guide rails 2 fixedly connected to the top of the base plate 1, and a clamping structure slidably installed between the two guide rails 2; the clamping structure includes a guide block 3 fixedly connected between the two guide rails 2, and a support block 4 fixedly connected to the top of the guide block 3, with two symmetrically distributed clamping rods 5 slidably connected inside the support block 4, and a gear 6 rotatably connected in the middle inside the support block 4; the two clamping rods 5 are centrally symmetrical inside the support block 4. The clamping rod 5 has a slot along its length, and a rack is provided on one side inside the slot. The clamping rod 5 meshes with the gear 6 on the outside through the rack. The clamping rod 5 has symmetrically distributed limiting grooves on both sides inside. The support block 4 has a protrusion that matches the limiting groove and is slidably connected inside the limiting groove. The end of the clamping rod 5 away from the inside of the support block 4 is fixedly connected to a clamping block 7. The casting body 16 is clamped between the two clamping blocks 7. The casting body 16 and the top of the support block 4 are in contact. A spring is fixedly connected between the two clamping blocks 7.

[0026] When the device is in use, first pull the handle 11 to drive the drive rod 10 to slide inside the guide groove 9. At this time, the drive rod 10 will drive the guide block 3 to move on the top of the base plate 1, and the guide block 3 will slide between the two guide rails 2, thereby removing the entire clamping structure from inside the protective cover 12.

[0027] After the clamping structure is removed from the protective cover 12, the clamping block 7 is pulled to move. During the movement of the clamping block 7, the clamping rod 5 will slide inside the support block 4. The slotted rack on the inner side of the clamping rod 5 will drive the gear 6 to rotate. The gear 6 will then drive another clamping rod 5 to slide inside the support block 4. Therefore, the two clamping rods 5 will move synchronously. When the two clamping blocks 7 move away from each other, the spring at the bottom will be stretched.

[0028] At this time, the bearing housing casting is placed on top of the support block 4, and the clamping block 7 is released. The springs at the bottom of the two clamping blocks 7 will pull the clamping blocks 7 closer to each other until the clamping blocks 7 and the two ends of the casting body 16 are in contact with each other and pressure is applied to the casting body 16. At this time, the two clamping blocks 7 clamp the casting body 16 and automatically adjust the casting body 16 to the middle of the support block 4 through their synchronous movement, which is convenient for quick disassembly and installation. Since the distance between the two clamping blocks 7 is adjustable, it can adapt to casting bodies 16 of different sizes.

[0029] Example 2: Based on Example 1, the following structure is also disclosed: Two symmetrically distributed support bars 8 are fixedly connected to the bottom of the base plate 1, and each support bar 8 is provided with a guide groove 9. A drive rod 10 is fixedly connected to each of the two guide grooves 9. The drive rod 10 slides through the base plate 1 and is fixedly connected to the bottom of the guide block 3. Handles 11 are fixedly connected to both ends of the drive rod 10. A protective cover 12 is fixedly connected to the top of the base plate 1, and a motor 13 is fixedly connected to the top of the handle 11 through a bracket. A rotating shaft 14 is fixedly connected to the output end of the motor 13, and the rotating shaft 14 extends into the interior of the protective cover 12. A ring of equally spaced grinding steel wires 15 is fixedly connected to the outside of the rotating shaft 14, and the grinding steel wires 15 and the rotating shaft 14 form a grinding brush. The grinding brush contacts the inner side of the casting body 16.

[0030] After the casting body 16 is installed, pull the handle 11 to move the drive rod 10, and push the guide block 3 into the protective cover 12 through the drive rod 10. At this time, the casting body 16 will also move into the protective cover 12. During this process, the grinding brush formed by the rotating shaft 14 and the grinding wire 15 will extend to the middle of the casting body 16, and drive the rotating shaft 14 to rotate inside the protective cover 12 through the motor 13 to grind the inner side of the casting body 16, thereby removing the burrs on the inner side of the casting body 16.

[0031] The grinding wire 15 is made of an elastic material, so that as it extends to the casting body 16, the grinding wire 15 can adapt to the size of the inner side of the casting body 16 by deformation, thereby adapting to the size of the middle hole of different casting bodies 16.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
