Description

Technical Field

[0001] The present application belongs to the field of structures of sanding discs on grinding machines, and specifically relates to a sanding disc with a block structure. Background Art

[0002] The existing grinding disc has an integral sponge part bonded to the disc body, and a flocking layer is provided on the sponge part to facilitate the bonding of sandpaper. During the grinding process, since the grinding disc is a plane as a whole, the surfaces that need to be polished during work are not all planes, and most of the grinding surfaces are curved surfaces, such as polishing of car bodies. When using a grinder, the area where the grinding disc and the grinding surface are frequently in contact is mainly concentrated in the middle area of ​​the grinding disc, causing the middle area of ​​the grinding disc to be worn and damaged in a short time. Replacing the grinding disc requires replacing the entire disc, which increases the cost of use. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide a grinding disc with a block structure, which can solve the problem of increased costs in the related art.

[0004] The present application provides a block structure grinding disc, including:

[0005] A first disk body, wherein the first disk body is an annular structure, and a middle portion of the first disk body is a hollow structure;

[0006] A second disk body, wherein the second disk body is an annular structure and is located in the middle of the first disk body, and the middle of the second disk body is a hollow structure; a third disk body, wherein the third disk body is located in the middle of the second disk body;

[0007] The first disk body, the second disk body and the third disk body are concentric, and the first disk body, the second disk body and the third disk body are placed in sequence. The first disk body is connected to the first connecting member, the first connecting member is provided with a first buckle, the first buckle passes through the corresponding through hole on the fixed plate, and the first buckle is clamped on the fixed plate. The second disk body is connected to the second connecting member, the second connecting member is provided with a second buckle, the second buckle passes through the corresponding through hole on the fixed plate, and the second buckle is clamped on the fixed plate. The third disk body is connected to the third connecting member, the third connecting member is provided with a third buckle, the third buckle passes through the corresponding through hole on the fixed plate, and the third buckle is clamped on the fixed plate.

[0008] The first disk body, the second disk body and the third disk body are simultaneously clamped on the fixed plate through the first connecting member, the second connecting member and the third connecting member. Each connecting body can be disassembled and replaced separately to avoid overall replacement, thereby reducing the use cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Example

[0016] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0017] In the following, in conjunction with the accompanying drawings, a block structure grinding disc provided in an embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0018] refer to Figure 1-4 , a block structure grinding disc provided in an embodiment of the present application includes:

[0019] The first disk body 1 is an annular structure, and the middle part of the first disk body 1 is a hollow structure; the second disk body 2, the second disk body 3 is an annular structure, and the second disk body 3 is located in the middle part of the first disk body 1, and the middle part of the second disk body 2 is a hollow structure; the third disk body 3, the third disk body 3 is located in the middle part of the second disk body 2; the first disk body 1, the second disk body 2 and the third disk body 3 are concentric, and the first disk body 1, the second disk body 2 and the third disk body 3 are placed in sequence.

[0020] The first disk body 1 is connected to the first connecting member 5, and the first connecting member 5 is provided with a first buckle 11, which passes through the corresponding through hole on the fixing plate 4, and the first buckle 11 is clamped on the fixing plate 4. The second disk body 2 is connected to the second connecting member 7, and the second connecting member 7 is provided with a second buckle 21, which passes through the corresponding through hole on the fixing plate 4, and the second buckle 21 is clamped on the fixing plate 4. The third disk body 3 is connected to the third connecting member 8, and the third connecting member 8 is provided with a third buckle 31, which passes through the corresponding through hole on the fixing plate 4, and the third buckle 31 is clamped on the fixing plate 4. The through holes and the buckles are one-to-one corresponding, and the first buckle 11, the second buckle 21 and the third buckle 31 are uniformly distributed circumferentially around the axis of the first disk body 1. The number of the first buckle 11, the second buckle 21 and the third buckle 31 is at least four respectively.

[0021] The first plate body 1 and the first connecting member 5 form a first connecting body, the second plate body 2 and the second connecting member 7 form a second connecting body, and the third plate body 3 and the third connecting member 8 form a third connecting body. The three connecting bodies are separated and the three connecting bodies are connected to the fixing plate 4 by snapping. Figure 4 As shown,

[0022] A plurality of dust outlet holes 6 are evenly arranged on the first plate body 1, the second plate body 2 and the third plate body 3. Figure 2 and Figure 3 As shown,

[0023] The first plate body 1, the second plate body 2 and the third plate body 3 are all sponges, and a flocking layer is also provided on the surface of the first plate body 1, the second plate body 2 and the third plate body 3 away from the fixed plate 4, so as to facilitate the bonding of sandpaper.

[0024] During use, the third disk 3 is most susceptible to wear, followed by the second disk 2, and the first disk 1 is least susceptible to wear. The specific wear is that the sponge layer becomes less elastic and thinner, which then leads to inability to continue working. After wear, the disk in the specific area can be replaced according to the degree of wear. Replacing an area separately can avoid replacing the entire area, saving material costs.

[0025] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
