Description

Technical Field

[0001] This utility model relates to the technical field of abrasive wheels, specifically an abrasive wheel that is easy to replace abrasive discs. Background Technology

[0002] Abrasive wheels are a common sanding tool widely used in machining, metal surface treatment, woodworking, and many other fields. During actual use, the abrasive discs on the abrasive wheel will gradually wear down as sanding continues. When the discs wear down to a certain extent, they need to be replaced with new ones in a timely manner to ensure sanding effectiveness and work efficiency.

[0003] Replacing existing abrasive wheels is a cumbersome process, typically requiring specialized tools such as wrenches to disassemble each fixing component before removing the old abrasive disc and installing the new one. This not only consumes a significant amount of time and effort but also easily damages other parts of the abrasive wheel during disassembly and installation, increasing operating costs and maintenance difficulty. To address these issues, existing equipment needs improvement. Utility Model Content

[0019] 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.

[0020] Please see Figure 1-4 This utility model provides a technical solution: an abrasive cloth wheel that is easy to replace abrasive discs, according to... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a mounting hole 101 is provided in the middle of the hub body 1 for connecting to the shaft of the grinding equipment. A first threaded groove 102 is provided on the front of the hub body 1 outside the mounting hole 101, and a second threaded groove 103 is provided at the outer end of the front of the hub body 1. Multiple engaging grooves 104 are equidistantly provided on the front of the hub body 1 between the second threaded groove 103 and the first threaded groove 102, and fixed connecting components 105 are provided inside the engaging grooves 104. Two adjacent fixed connecting components 105 are respectively connected to both sides of the abrasive disc body 2. The fixed connecting components 105 facilitate the installation and fixation of the abrasive disc body 2. The abrasive disc body 2 has a fan-shaped annular structure, and the abrasive disc body 2 is located on both sides of the fixed connecting components 105, respectively in the second threaded groove 103 and... Inside the first threaded groove 102, and inside the second threaded groove 103 and the first threaded groove 102, a first threaded seat 3 and a second threaded seat 5 are respectively provided on the outer side of the sand sheet body 2. The first threaded seat 3 has external threads on both its inner and outer sides, and the first threaded seat 3 is threadedly connected to the internal thread inside the first threaded groove 102. The second threaded seat 5 has external threads on its inner side, and the second threaded seat 5 is threadedly connected to the internal thread inside the second threaded groove 103. The connection between the first threaded seat 3 and the first threaded groove 102 facilitates the fixing of the side of the sand sheet body 2 near the mounting hole 101 inside the first threaded groove 102. The connection between the second threaded seat 5 and the second threaded groove 103 facilitates the fixing of the outer end of the sand sheet body 2 inside the second threaded groove 103, thereby completing the installation and fixing of the sand sheet body 2.

[0021] Specifically, the fixed connection component 105 includes a locking seat 1051 and a positioning frame 1052. The locking seat 1051 is provided with the positioning frame 1052 inside, and the positioning frame 1052 is provided with a rubber elastic pad 1053 inside. The rubber elastic pad 1053 and the positioning frame 1052 are used together to improve the tightness of the connection between one side of the sanding disc body 2 and the locking seat 1051. Both the locking seat 1051 and the positioning frame 1052 are U-shaped structures and are made of metal. The positioning frame 1052 is symmetrically provided with elastic buttons 1054 at equal intervals on its outer side. The position of the elastic buttons 1054 corresponds one-to-one with the position of the positioning through holes 1055 opened on the outer side of the locking seat 1051. The elastic buttons 1054 engage with the positioning through holes 1055 to fix the positioning frame 1052 inside the locking seat 1051 and prevent displacement.

[0022] To further explain, both the first threaded seat 3 and the second threaded seat 5 are annular structures, and the first threaded seat 3 is detachably connected to the two sides of its front side with a first extension rod 4. The first extension rod 4 facilitates the installation and removal of the first threaded seat 3. At the same time, the upper and lower ends of the second threaded seat 5 are detachably connected to a second extension rod 6. The second extension rod 6 facilitates the installation and removal of the second threaded seat 5.

[0023] In use, first connect and fix the middle of the front and rear sides of the abrasive disc body 2 to the rubber elastic pads 1053 set inside the adjacent positioning frames 1052. Then, install and fix the positioning frames 1052 inside the locking seat 1051 through the elastic button 1054. Next, move the locking seat 1051 laterally into the locking groove 104 to engage, so that the left and right sides of the abrasive disc body 2 are respectively located inside the first threaded groove 102 and the second threaded groove 103. Then, rotate the first threaded seat 3 to connect with the first threaded groove 102 through the first extension rod 4, and rotate the second threaded seat 3 through the second extension rod 6. The seat 5 is connected to the second threaded groove 103 to install and fix the left and right sides of the sanding disc body 2, thereby completing the installation. Conversely, when disassembling and replacing the sanding disc body 2, firstly, the first threaded seat 3 is rotated to separate from the first threaded groove 102 by the first extension rod 4, and the second threaded seat 5 is rotated to separate from the second threaded groove 103 by the second extension rod 6. Then, the locking seat 1051 is moved to separate from the locking groove 104. Then, the elastic button 1054 is pressed through the positioning through hole 1055 to separate the positioning frame 1052 from the locking seat 1051, thereby facilitating the disassembly of the damaged sanding disc body 2.
