Description

Technical Field

[0001] The utility model relates to the technical field of polishing devices, in particular to a spoke mirror polishing device. Background Art

[0002] The spoke is a device that protects the rim and spokes of the vehicle wheel. It is characterized by a pair of circular cover plates. The diameter of the cover plates is close to the diameter of the rim. There is a hole in the center of the cover plate that is larger than the wheel's rotating axis. There is an opening near the edge of the cover plate. There is an annular wheel plate on the edge of the cover plate. The curved surface of the wheel plate can fit tightly with the curved surface of the rim. The production of steel spokes must ensure a smooth surface, so they need to be ground and polished.

[0003] The Chinese utility model with authorization announcement number CN218488086U discloses a conveniently adjustable grinding and polishing device for processing steel spokes. When in use, the device is configured to push and pull a clamping plate by a second telescopic rod to achieve clamping and loosening of the steel spokes, so that the device can grind and polish steel spokes of different sizes. However, the device has certain defects in actual use. For example, the contact surface of the clamping plate with the spoke is small, which increases the risk of sliding of the spoke during the grinding and polishing process. At the same time, the force during clamping cannot be precisely controlled. A large force can easily cause damage to the outer wall of the spoke, and a small clamping force can easily cause unstable clamping. Therefore, it is necessary to propose a spoke mirror polishing device to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a spoke mirror polishing device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] Preferably, the driving assembly includes a threaded rod rotatably connected to the inner wall of the slide groove, and the slider is threadedly connected to the threaded end of the threaded rod.

[0011] Preferably, a plurality of servo motors are fixedly connected to the side walls of the workbench, and the output shafts of the plurality of servo motors are coaxially fixedly connected to the adjacent threaded rods.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model adopts the flexible covering design of the rubber belt, so that the outer wall of the spoke is subjected to uniform covering force during the clamping process, avoiding the risk of sliding caused by the small contact area when clamping with traditional plywood. At the same time, the flexibility of the rubber belt not only protects the outer wall of the spoke from damage, but also effectively increases the clamping force, ensuring the stability of the spoke during the grinding and polishing process, and preventing sliding or displacement.

[0021] 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 the embodiments.

[0022] Reference Figure 1-5 A spoke mirror polishing device includes a workbench 1 and a polishing assembly 5. A plurality of groups of slide grooves 3 are provided on the upper end of the workbench 1. Slide blocks 8 are slidably connected in the plurality of slide grooves 3. A side plate 2 is fixedly connected to the upper end of the workbench 1. The outer wall of the side plate 2 is L-shaped. The polishing assembly 5 is installed on the lower end surface of the side plate 2. The upper end of the slide block 8 is fixedly connected to the bottom plate 9. The end surface of the bottom plate 9 is rotatably connected to two groups of rotating drums 10. The outer walls of the two groups of rotating drums 10 are fixedly connected with rubber belts 11. A driving assembly for driving the slide block 8 to slide is installed in the slide groove 3; the two groups of rotating drums 10 are driven to slide by the slider 8, which can drive the rubber belt 11 to approach and cover the outer wall of the spoke. The flexibility of the rubber belt 11 can adapt to spokes of different shapes, ensuring that the spoke is stably clamped during the polishing process and avoiding damage to the spoke surface during clamping.

[0023] The driving assembly includes a threaded rod 6 rotatably connected to the inner wall of the slide 3, a slider 8 is threadedly connected to the threaded end of the threaded rod 6, a limit rod 7 is fixedly connected in the slide 3, and the slider 8 is slidably connected to the outer wall of the limit rod 7. The ends of the two sets of rotating drums 10 are fixedly connected to the top plate, and the upper end of the top plate is rotatably connected to the rotating block 12. The rotating block 12 is coaxially fixedly connected to the adjacent rotating drum 10. The outer wall of the rotating block 12 is provided with multiple groups of rotating grooves 13, and the multiple groups of rotating grooves 13 are annularly distributed on the outer wall of the rotating block 12. The upper end of the top plate is fixedly connected to the sliding rod 14. The sliding rod The outer wall 14 is slidably connected with a clamping block 15, and the end of the clamping block 15 is clamped in the inside of the rotating groove 13. The side wall of the workbench 1 is fixedly connected with multiple groups of servo motors 4, and the output shafts of the multiple groups of servo motors 4 are coaxially fixedly connected with the adjacent threaded rods 6; with the help of the rotation of the rotating drum 10, the rubber belt 11 can be wound around the outer wall of the rotating drum 10, so that the rubber belt 11 is in a taut state, thereby further improving the friction force when clamping the spoke, effectively preventing the spoke from sliding during the grinding and polishing process, thereby ensuring the stability and consistency of the processing.

[0024] In the present invention, when the device is used specifically: the operator controls the servo motor 4 to drive the threaded rod 6 to rotate according to the size and shape of the spoke, driving the slider 8 to slide along the slide groove 3. At this time, the slider 8 moves together with the base plate 9 and the rotating drum 10 connected thereto, and the rubber belt 11 gradually approaches the outer wall of the spoke. When the slider 8 slides to the appropriate position, the rubber belt 11 will cover and fit the outer wall of the spoke. The flexibility of the rubber belt 11 ensures that the surface of the spoke will not be directly damaged, and the covering structure provides sufficient clamping force.

[0025] At the same time, the clamping block 15 can be lifted out of the rotating groove 13, and the rotating block 12 can be rotated to synchronously drive the rotating drum 10 to rotate. The rubber belt 11 is then wound tightly, further increasing the contact force and friction with the spoke surface, ensuring that the spoke will not slip during the polishing process.

[0026] After the spoke is clamped and stabilized, the polishing assembly 5 is started to grind and polish the surface of the spoke. The flexibility and covering force of the rubber belt 11 can ensure that the spoke will not slide or rotate due to external forces during the polishing process.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
