Description

Technical Field

[0001] This utility model relates to the field of polishing wheel technology, specifically a polishing wheel with quick assembly and disassembly function. Background Technology

[0002] A polishing wheel is a tool used for grinding and polishing. It is made of elastic materials such as cotton cloth, wool, and nylon. It uses high-speed rotation to rub against the surface, using abrasives to remove scratches, oxide layers and other defects, thereby improving the smoothness. There are various types, such as cloth wheels, sisal wheels and nylon wheels. They are suitable for metal processing, woodworking, automobile repair and other fields, and can handle complex workpieces to achieve fine polishing.

[0003] In industrial production and various processing scenarios, polishing wheels are key consumables with a high frequency of wear and replacement. Currently, most polishing wheels on the market are connected to the main shaft of the equipment by conventional bolt fastening or nut tightening. Taking a common metal processing workshop as an example, when workers replace polishing wheels, they need to use wrenches and other tools to unscrew multiple bolts or nuts one by one. The whole process is cumbersome, and because of the large number of bolts and the compact installation position, it is difficult to operate in a small space, which greatly consumes manpower and time costs.

[0014] This invention provides a polishing wheel with quick assembly and disassembly. It offers the following advantages:

[0015] (1) In this utility model, the connecting sleeve slides downward on the outer wall of the connecting round plate. The bottom of the connecting sleeve will contact the upper surface of the connecting rod. At this time, the connecting rod is pushed inward and slides on the inner wall of the sliding hole.

[0025] 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.

[0026] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] Example 1

[0028] A preferred embodiment of the polishing wheel with quick assembly / disassembly function provided by this utility model is, for example... Figure 1-5 As shown: A polishing wheel with quick assembly and disassembly function includes a polishing wheel 1, a fixed circular plate 2, an assembly and disassembly assembly 3 and a fastening assembly 4, wherein the fixed circular plate 2 is fixedly connected to the upper surface of the polishing wheel 1;

[0029] The disassembly / assembly assembly 3 includes a connecting circular plate 311, a slide rail 312, and a fixing block 313. The connecting circular plate 311 is fixedly connected to the upper surface of the fixing circular plate 2. A connecting groove is formed on the upper surface of the connecting circular plate 311, and a sliding hole is formed on the outer wall of the connecting circular plate 311. The slide rail 312 is fixedly connected to the inner wall of the connecting groove, and the fixing block 313 is fixedly connected to the inner wall of the slide rail 312. The fixing block 313 is fixedly connected to the inner wall of the connecting groove. A spring 314 is provided on one side of the fixing block 313, and one end of the spring 314 is fixedly connected to the fixing block 313. A sliding block 315 is provided on the inner wall of the slide rail 312, and the sliding block 315 is slidably connected to the inner wall of the slide rail 312. The other end of the spring 314 is fixedly connected to the sliding block 315, and a connecting rod 316 is provided on the other side of the sliding block 315. Rod 316 is fixedly connected to the other side of sliding block 315. The connecting rod 316 is slidably connected to the inner wall of sliding hole 1. A sliding groove is provided on the upper surface of the connecting rod 316. A support block 317 is provided on the upper surface of the fixed block 313. The support block 317 is fixedly connected to the upper surface of the fixed block 313. A fixing plate 318 is provided on the upper surface of the support block 317. The fixing plate 318 is fixedly connected to the upper surface of the support block 317. A connecting frame 319 is provided on the upper surface of the sliding block 315. The connecting frame 319 is fixedly connected to the upper surface of the sliding block 315. The connecting frame 319 is slidably connected to the outer wall of the fixing plate 318. A fixing plate 320 is provided at one end of the fixing plate 318. The fixing plate 320 is fixedly connected to one end of the fixing plate 318. The bottom of the fixing plate 320 is fixedly connected to the slide rail 312.

[0030] Furthermore, in this embodiment, the connecting sleeve 411 slides downward along the outer wall of the connecting circular plate 311. As the connecting sleeve 411 slides down, its bottom gradually contacts the upper surface of the connecting rod 316. At this time, an inward pushing force is applied to the connecting rod 316, causing the connecting rod 316 to slide on the inner wall of the sliding hole. Since the connecting rod 316 is fixedly connected to the sliding block 315, the sliding block 315 also slides on the inner wall of the slide rail 312 while the connecting rod 316 slides. The sliding block 315 is fixed to the connecting frame 319, thereby causing the connecting frame 319 to slide on the outer wall of the fixing plate 318. During this process, spring 314 will be compressed and contract. When the connecting sleeve 411 slides down to contact the upper surface of the fixed circular plate 2, spring 314 loses its external force restraint and begins to rebound. The elastic force generated by it drives the sliding block 315 and the connecting rod 316 connected to it to slide, and finally makes the connecting rod 316 slide into the inner wall of the sliding hole 412, thereby fixing the connecting sleeve 411. When it is necessary to loosen the connecting sleeve 411, simply pull the connecting sleeve 411 upward. During the pulling process, the inner wall of the connecting sleeve 411 will squeeze the connecting rod 316, forcing the connecting rod 316 to return to its original position.

[0031] Example 2

[0032] Based on Embodiment 1, a preferred embodiment of the polishing wheel with quick assembly / disassembly function provided by this utility model is, for example... Figure 1-5 As shown: Fastening assembly 4 includes a connecting sleeve 411, a second sliding hole 412, and a second slide rail 413. The connecting sleeve 411 is slidably connected to the outer wall of the connecting circular plate 311. The second sliding hole 412 is provided on the outer wall of the connecting sleeve 411. The second slide rail 413 is fixedly connected to the outer wall of the connecting sleeve 411. A first limiting plate 414 is provided on the upper surface of the second slide rail 413. The first limiting plate 414 is fixedly connected to the upper surface of the second slide rail 413. The bottom of the first limiting plate 414 is provided with... There is a second spring 415, one end of which is fixedly connected to the bottom of the first limiting plate 414. A sliding block 416 is provided on the inner wall of the second slide rail 413. The sliding block 416 is slidably connected to the inner wall of the second slide rail 413. The upper surface of the sliding block 416 is fixedly connected to the other end of the second spring 415. The sliding block 416 is slidably connected to the inner wall of the sliding groove. A second limiting plate 417 is provided at the bottom of the second slide rail 413. The second limiting plate 417 is fixedly connected to the bottom of the second slide rail 413.

[0033] Furthermore, in this embodiment, before the connecting rod 316 enters the second sliding hole 412, the sliding block 416 is first pushed upward along the second slide rail 413 to compress the second spring 415 and store energy. After the connecting rod 316 is fully inserted into the second sliding hole 412, the constraint on the second limiting plate 417 is released. At this time, the compressed second spring 415 quickly rebounds, driving the sliding block 416 to move downward along the second slide rail 413, with its lower end precisely embedded in the sliding groove of the connecting rod 316, forming a stable lock. To unlock, simply reverse the operation of the second limiting plate 417 to compress the second spring 415 again, and the sliding block 416 can then exit from the sliding groove, releasing the connecting rod 316.

[0034] In use, firstly, push the sliding block 416 upwards along the second slide rail 413 to compress the second spring 415 and store energy. Then, slide the connecting sleeve 411 downwards along the outer wall of the connecting circular plate 311. As the connecting sleeve 411 slides down, its bottom will gradually contact the upper surface of the connecting rod 316. At this time, apply an inward pushing force to the connecting rod 316, and the connecting rod 316 will slide on the inner wall of the first sliding hole. Since the connecting rod 316 is fixedly connected to the first sliding block 315, the first sliding block 315 will also slide on the inner wall of the first slide rail 312 while the connecting rod 316 is sliding. The first sliding block 315 is also fixed to the connecting frame 319, which in turn drives the connecting frame 319 to slide on the outer wall of the first fixing plate 318. During this process, spring 314 is compressed and contracts. When the connecting sleeve 411 slides down to contact the upper surface of the fixed circular plate 2, spring 314 loses its external restraint and begins to rebound. The elastic force it generates drives sliding block 315 and the connecting rod 316 connected to it to slide, eventually causing the connecting rod 316 to slide into the inner wall of sliding hole 412, thereby fixing the connecting sleeve 411. Then, after the connecting rod 316 has fully entered sliding hole 412, the restraint on limit plate 417 is released. At this time, the compressed spring 415 rebounds quickly, driving the sliding block 416 to move downward along slide rail 413. Its lower end is precisely embedded in the sliding groove of connecting rod 316, forming a stable lock. When unlocking, simply reverse the operation of the second limiting plate 417 to compress the second spring 415 again, and the sliding block 416 can exit from the sliding groove, releasing the connecting rod 316. Then, pull the connecting sleeve 411 upward. During the pulling process, the inner wall of the connecting sleeve 411 will squeeze the connecting rod 316, forcing the connecting rod 316 to return to its original position, so that the polishing wheel 1 can be quickly disassembled and assembled.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
