[0018] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0019] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0020] like Figure 1 As shown, this embodiment provides an integrated diamond floor grinding disc, including a disc body 1 and a cutter head 2, wherein the cutter head 2 is made of diamond, which has high strength and good wear resistance. The disc body 1 is usually circular, but can also be other shapes, which is not limited in this embodiment.

[0021] like Figure 2 As shown, a positioning through hole 3 for positioning is provided at the center of the cutter disc body 1, and mounting through holes 4 for installation are provided around it. The number of mounting through holes 4 is determined according to actual installation requirements. This embodiment takes four mounting through holes 4 as an example.

[0022] like Figure 3 As shown, the cutter head body 1 of this embodiment is provided with an assembly through hole 5 that passes through the front and back of the cutter head body 1, and the diameter of the assembly through hole 5 near the back is larger than the diameter of the assembly through hole 5 near the front. The cutter head 2 is provided with a connecting rod 6 that is adapted to the assembly through hole 5, and is fixedly connected to the assembly through hole 5 through the connecting rod 6, so that the cutter head 2 is fixedly connected to the front of the cutter head body 1. The purpose of this arrangement is to enlarge the end of the connecting rod 6, so that the connecting rod 6 will not withdraw from the assembly through hole 5 during use. Compared with the existing manual welding, the connection between the cutter head 2 and the cutter head body 1 is more secure and does not loosen.

[0023] In this embodiment, each cutter head 2 and the corresponding connecting rod 6 are integrally formed by high-temperature pressing of diamond powder. The specific manufacturing process is as follows:

[0024] The cutter head body 1 is placed on the mold of the cutter head 2, and diamond powder is poured into the mold from the assembly through hole, and the diamond powder is filled to the upper end of the assembly hole. After pressing, heating, and cooling, the diamond powder in the mold forms the diamond cutter head 2, and the diamond powder in the assembly through hole 5 forms an embedded riveted connecting rod 6 structure, which is integrated with the cutter head body 1 and firmly connected. This manufacturing method replaces the existing manual welding, avoids the damage to the cutter head 2 caused by secondary high temperature, and also avoids the harmful gas generated by welding, thereby improving the protection of the human body.

[0025] like Figure 5 As shown, the cross-sectional area of ​​the upper portion of the cutter head 2 in this embodiment is smaller than that of the lower portion. The shape of the cutter head 2 is not limited, and its cross-sectional shape can be polygonal, circular, elliptical or trapezoidal, or other shapes. However, the cutter head 2 of any shape is a structure that is small at the top and large at the bottom. The purpose of this setting is to reduce the demoulding resistance, and compared with the existing cutter head 2 structure, demoulding is easier.

[0026] In addition, in this embodiment, there are multiple cutter heads 2, all of which are distributed along the circumferential direction on the front of the cutter head body 1, and all of which are evenly distributed along the circumferential direction. The specific number of cutter heads 2 is selected according to actual conditions, and usually three or four cutter heads 2 are provided, but not limited to three or four. Figure 1 and Figure 4 As shown, each cutter head 2 is fixedly connected to the cutter disc body 1 via one or more connecting rods 6. The number of connecting rods 6 is also determined according to actual conditions and is not limited in this embodiment.
