Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub polishing, in particular to a vehicle wheel hub polishing device. Background Art

[0002] For example, in a car wheel hub polishing device disclosed on the Chinese Patent Network (application number: 202122637310.2), when limiting the position of an object, the two clamping plates are controlled by rotating two screws to move toward each other to clamp the object. However, the clamping mechanism cannot control the clamping force and cannot accurately grasp the timing after the wheel hub is clamped. This will cause the wheel hub to be damaged when the clamping force is large, and when the clamping force is small, the wheel hub will be misaligned during polishing, causing trouble for subsequent work.

[0003] In addition, manually turning the screw to clamp the wheel hub with the clamping plate consumes a certain amount of physical strength, and the screw lacks a limit device. When the wheel hub is polished, vibration will be generated. The vibration is transmitted from the clamping plate to the screw, causing the screw to loosen, thereby reducing the clamping force of the clamping plate, making it impossible for the wheel hub to remain in a stable position, affecting the polishing work.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-Figure 5A car wheel hub polishing device includes a base 1. In order to conveniently control the clamping mechanism to clamp an object, a control device is arranged inside the base 1. The control device includes a control motor 2, an adjusting rod 3, two moving blocks 4, two moving plates 5, two clamping plates 6 and a stop switch 7. When the control motor 2 is started, the rotating shaft drives the adjusting rod 3 to rotate. The adjusting rod 3 rotates to make the two moving blocks 4 drive the two moving plates 5 to move horizontally toward each other. When the clamping plates 6 clamp the object, they squeeze the stop switch 7 to stop the control motor 2.

[0026] In order to facilitate the control of the two moving blocks 4 to be stuck in the slot 8 and move horizontally toward each other, the control motor 2 is fixedly installed inside the right end of the base 1, and the adjusting rod 3 is fixedly connected to the rotating shaft of the control motor 2. A slot 8 is opened inside the base 1, and the two moving blocks 4 are slidably inserted into the inside of the slot 8. The two moving blocks 4 are horizontally symmetrically distributed with the axis of the base 1 as the symmetry center. When the control motor 2 is started, the rotating shaft drives the adjusting rod 3 to rotate. The adjusting rod 3 is composed of two horizontally symmetrical threaded rods fixedly connected. When rotating, the two moving blocks 4 will be stuck in the slot 8 and move horizontally toward each other.

[0027] In order to ensure that the movable plate 5 moves horizontally close to the upper surface of the base 1, the outer surface of the adjusting rod 3 is connected to the internal thread of the movable block 4, and the two movable plates 5 are respectively fixedly mounted on the upper surfaces of the two movable blocks 4, and the lower surfaces of the two movable plates 5 are slidingly connected to the upper surface of the base 1. The two movable blocks 4 drive the movable plate 5 to move, and the movable plate 5 moves horizontally close to the upper surface of the base 1.

[0028] In order to ensure that the splint 6 remains horizontal and moves linearly in front of the movable plate 5, a slide groove 51 is opened inside the two movable plates 5, and a sliding card plate 52 is slidably inserted inside the slide groove 51. The splint 6 is fixedly installed on the front end surface of the sliding card plate 52, and the stop switch 7 is fixedly installed inside the movable plate 5. The stop switch 7 is electrically connected to the control motor 2 through a wire. A spring 53 is fixedly connected to the outer surface of the sliding card plate 52, and the other end of the spring 53 is fixedly connected to the inside of the slide groove 51. The sliding card plate 52 is stuck in the slide groove 51 and moves horizontally, ensuring that the splint 6 remains horizontal and moves linearly in front of the movable plate 5. When the stop switch 7 is squeezed, the control motor 2 will stop.

[0029] In order to facilitate the adjustment of the height of the mounting block 15, a mounting seat 11 is fixedly installed on the upper surface of the base 1, an electric telescopic rod 12 is fixedly installed inside the mounting seat 11, a mounting frame 13 is fixedly installed at the lower end of the electric telescopic rod 12, a rotating rod 14 is rotatably connected inside the lower end of the mounting frame 13, and a mounting block 15 is fixedly installed on the outer surface of the rotating rod 14. When the electric telescopic rod 12 is started, the mounting frame 13 is controlled to move up and down to adjust the height of the mounting block 15, and the rotating rod 14 is clamped at the lower end of the mounting frame 13 and rotates.

[0030] In order to facilitate the adjustment of the inclination angle of the grinding roller 18, a rotating motor 16 is fixedly installed inside the right end of the mounting frame 13, and the rotating shaft of the rotating motor 16 is fixedly connected to the outer surface of the rotating rod 14. A servo motor 17 is installed inside the mounting block 15, and the grinding roller 18 is rotatably connected inside the lower end of the mounting block 15. The upper surface of the grinding roller 18 is fixedly connected to the rotating shaft of the servo motor 17. When the rotating motor 16 is started, the rotating shaft drives the rotating rod 14 to rotate to adjust the inclination angle of the grinding roller 18. When the servo motor 17 is started, the rotating shaft drives the grinding roller 18 to rotate.

[0031] By setting a control device, when polishing the wheel hub, the wheel hub to be polished is placed on the base 1, and then the control motor 2 is started, so that the rotating shaft drives the adjusting rod 3 to rotate, so that the two moving blocks 4 are stuck in the slot 8 and move horizontally toward each other, driving the moving plate 5 and the clamping plate 6 to move. When the two clamping plates 6 clamp the wheel hub, the clamping plate 6 will squeeze the stop switch 7 to stop the control motor 2. At this time, the spring 53 will contract, and the elastic force generated by the contraction of the spring 53 will clamp the object to ensure that the clamping force is appropriate. Then the electric telescopic rod 12 is started to control the mounting frame 13 to move downward, and then the rotating motor 16 is started to control the rotating rod 14 to rotate, and the inclination angle of the grinding roller 18 is adjusted. The servo motor 17 is started to control the grinding roller 18 to rotate, so as to facilitate the grinding of the wheel hub, thereby achieving the effect of ensuring the appropriate clamping force and the stable limit of the wheel hub.

[0032] Working principle: when polishing the wheel hub, place the wheel hub to be polished on the base 1, and then start the control motor 2, let the rotating shaft drive the adjusting rod 3 to rotate, so that the two moving blocks 4 are stuck in the slot 8 and move horizontally toward each other, driving the moving plate 5 and the clamping plate 6 to move. When the two clamping plates 6 clamp the wheel hub, the clamping plate 6 will squeeze the stop switch 7 to stop the control motor 2. At this time, the spring 53 will contract, and the elastic force generated by the contraction of the spring 53 will clamp the object, and then start the electric telescopic rod 12 to control the mounting frame 13 to move downward, and then start the rotating motor 16 to control the rotating rod 14 to rotate, adjust the inclination angle of the grinding roller 18, and start the servo motor 17 to control the grinding roller 18 to rotate, so as to facilitate the grinding of the wheel hub.
