[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-5A grinding device for processing drive axle housings includes a base 1, a protective shell 2 fixedly mounted on the upper surface of the base 1, a mounting bracket 3 fixedly mounted on the upper surface of the base 1, a first three-jaw chuck 16 rotatably connected inside the mounting bracket 3, a fixing plate 17 disposed above the base 1, a rotary motor 18 fixedly mounted on the left side of the fixing plate 17, and a second three-jaw chuck 19 fixedly mounted on the output end of the rotary motor 18. The drive axle housing is clamped by the first three-jaw chuck 16 and the second three-jaw chuck 19, and the power provided by the rotary motor 18 drives the first three-jaw chuck 16 and the second three-jaw chuck 19 to rotate, thereby achieving the function of clamping and flipping the drive axle housing.

[0025] The mounting bracket 3 has a threaded rod 4 rotatably connected inside. A rotating motor 5 is fixedly installed on the right side of the mounting bracket 3. The right end of the threaded rod 4 is fixedly connected to the output end of the rotating motor 5. A movable plate 6 is threadedly connected to the outer surface of the threaded rod 4. Two sliding rods 24 are fixedly installed on the inner wall of the mounting bracket 3. The outer surface of each sliding rod 24 is slidably connected to the inner wall of the movable plate 6. The installation of the sliding rods 24 restricts the movement trajectory of the movable plate 6, thereby preventing the movable plate 6 from deviating from the movement trajectory during movement, and thus ensuring the stability of the movement of the movable plate 6.

[0026] Two electric push rods 7 are fixedly installed on the bottom surface of the movable plate 6. The telescopic ends of the two electric push rods 7 are jointly fixedly installed with a connecting plate 8. Connecting bearings 20 are fixedly installed on the opposite sides of the first three-jaw chuck 16 and the second three-jaw chuck 19. The opposite sides of the two connecting bearings 20 are fixedly connected to the outer surface of the fixed plate 17 and the outer surface of the mounting bracket 3, respectively. The installation of the connecting bearings 20 plays a role in stabilizing the first three-jaw chuck 16 and the second three-jaw chuck 19, thereby preventing the first three-jaw chuck 16 and the second three-jaw chuck 19 from shaking when rotating, thus ensuring the stability of the rotation of the first three-jaw chuck 16 and the second three-jaw chuck 19.

[0027] Two concave blocks 9 are fixedly installed on the bottom surface of the connecting plate 8. Each concave block 9 is rotatably connected to a placement rack 10. Each placement rack 10 is fixedly installed with a collection cover 11 on its inner wall. Each placement rack 10 is fixedly installed with a worm gear 27 on its left end. Each concave block 9 is fixedly installed with a connecting rack 28 on its left side. Each connecting rack 28 is rotatably connected with a worm 29. The outer surface of each worm 29 meshes with the outer surface of the worm gear 27. By utilizing the self-locking function of the worm gear 27 and the worm 29, the angle of the collection cover 11 can be adjusted, allowing workers to adjust the angle of the collection cover 11 according to their needs, thus better collecting the metal shavings generated during grinding.

[0028] The upper surface of the mounting bracket 3 is fixedly mounted with a collection box 12 and an air pump 13. The air inlet of the air pump 13 extends into the interior of the collection box 12. An electric telescopic rod 21 is fixedly mounted on the outer surface of the fixing plate 17. The bottom surface of the electric telescopic rod 21 is fixedly connected to the upper surface of the base 1. The power provided by the electric telescopic rod 21 drives the fixing plate 17 to move, thereby adjusting the position of the second three-jaw chuck 19, which facilitates the clamping and grinding of different models of drive axle housings.

[0029] A filter screen 14 is fixedly installed on the inner wall of the collection box 12. Two sliders 22 are fixedly installed on the bottom surface of the fixed plate 17. Two grooves 23 are opened on the upper surface of the base 1. Each slider 22 is slidably connected inside the groove 23. The installation of the sliders 22 and the grooves 23 restricts the movement trajectory of the fixed plate 17, thereby preventing the fixed plate 17 from deviating from the movement trajectory when moving, and thus ensuring the stability of the movement of the fixed plate 17.

[0030] A conveying pipe 15 is fixedly connected to the left side of the collection box 12. The end of the conveying pipe 15 away from the collection box 12 extends into the interior of the collection cover 11. A stepper motor 25 is fixedly installed on the bottom surface of the connecting plate 8. A grinding tool 26 is fixedly installed on the output end of the stepper motor 25. The grinding tool 26 is rotated by the power provided by the stepper motor 25, thereby grinding the drive axle housing.

[0031] The working principle of this utility model is as follows: In use, the worker places the drive axle housing between the first three-jaw chuck 16 and the second three-jaw chuck 19. Then, the worker opens the electric telescopic rod 21 via an external remote control device. The power provided by the electric telescopic rod 21 drives the fixed plate 17 to move, thereby adjusting the distance between the first three-jaw chuck 16 and the second three-jaw chuck 19 according to the length of the drive axle housing. Then, the first three-jaw chuck 16 and the second three-jaw chuck 19 clamp and limit the drive axle housing. After that, the worker closes the protective shell 2 and uses the power provided by the rotary motor 5 to drive the threaded rod 4 to rotate, thereby causing the threaded rod 4 to drive the moving plate 6 to move. At the same time, the electric push rod 7 is used... The provided power drives the connecting plate 8 to move up and down, thereby adjusting the height of the grinding tool 26. Then, the power provided by the stepper motor 25 drives the grinding tool 26 to rotate, thus grinding the drive axle housing. During the grinding process, the power provided by the air pump 13 discharges the gas inside the collection box 12, creating a negative pressure inside the collection box 12. This allows the metal debris generated during the grinding process to enter the collection box 12 after passing through the collection cover 11 and the conveying pipe 15, thereby collecting the metal debris. At the same time, the protective shell 2 isolates the metal debris generated during the grinding process, preventing it from flying everywhere and thus avoiding any impact on surrounding personnel or the environment.
