[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a high-strength diamond grinding wheel proposed by the utility model comprises a steel substrate 1 and an isolation layer 2. The isolation layer 2 is installed on the outer surface of the steel substrate 1. The steel substrate 1 provides fixing points for the isolation layer 2, the cooling layer 3, the connecting hole 5, the threaded fixing hole 6, the first extension rod 7 and the second extension rod 9 installed on its outer surface and inside. At the same time, the steel substrate 1 is made of stainless steel to improve the structural strength of the diamond grinding wheel. The isolation layer 2 is electroplated on the outer surface of the diamond grinding wheel with aluminum alloy to provide a fixing point for the cutting layer 4 installed on its outer surface. When heat is conducted to the inside of the isolation layer 2, the isolation layer 2 conducts the heat to the inside of the steel substrate 1. The outer surface of the isolation layer 2 is installed with the cutting layer 4. The cutting layer 4 is made of diamond and resin bonded and sintered. When the cutting layer 4 comes into contact with the external metal part, the metal part is cut under the drive of the external motor. A connecting hole 5 is opened through the front of the steel base 1. The connecting hole 5 is opened through the front of the steel base 1 to provide a fixing space for the transmission components of the motor. Before using the device, the external connecting rod is inserted into the inside of the connecting hole 5 to complete the preliminary fixation of the external transmission components. Eight groups of threaded fixing holes 6 are opened through the outer surface of the connecting hole 5, and the threaded fixing holes 6 are located on the outside of the connecting hole 5. Before using the device, the external bolts are inserted into the inside of the threaded fixing holes 6 and the external bolts are inserted into the inside of the external transmission disk to complete the fixation of the steel base 1.

[0024] The working principle of a high-strength diamond grinding wheel based on Example 1 is: first, an external connecting rod is inserted into the inside of the connecting hole 5 to complete the preliminary fixation of the external transmission component, and then the external bolt is inserted into the inside of the external transmission disk to complete the fixation of the diamond grinding wheel. When the rotational force is transmitted to the inside of the diamond grinding wheel, the cutting layer 4 contacts the external metal part, and the metal part is cut under the drive of the external motor.

[0025] Embodiment 2

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, a high-strength diamond grinding wheel proposed by the utility model, compared with the first embodiment, this embodiment also includes: a steel substrate 1 and a cooling layer 3, the cooling layer 3 is arranged inside the inner wall of the steel substrate 1, and the cooling layer 3 is filled with water. When heat is conducted to the inside of the cooling layer 3, the water inside the cooling layer 3 absorbs the heat to prevent the diamond grinding wheel from being softened, thereby improving the structural strength and service life of the diamond grinding wheel.

[0027] Embodiment 3

[0028] like Figure 1 , Figure 2 and Figure 4As shown, a high-strength diamond grinding wheel proposed by the utility model, compared with the first embodiment, this embodiment also includes: a steel base 1 and a first extension rod 7, the first extension rod 7 is installed on the inner wall of one side of the steel base 1, the first extension rod 7 is installed to one side of the steel base 1, and a connection point is provided for a shielding rod 8 wrapped and connected to its outer surface. When the impact force is transmitted to one side of the steel base 1, the first extension rod 7 shrinks to the inner side of the shielding rod 8, the outer surface of the first extension rod 7 is wrapped and connected to the shielding rod 8, the shielding rod 8 is wrapped and connected to the outer surface of the first extension rod 7 and the second extension rod 9, and the inner side of the shielding rod 8 is embedded and connected to the second extension rod 9. The tail end of the second extension rod 9 is connected to the other side of the steel base 1, and the second extension rod 9 is installed to the other side of the steel base 1 to provide a connection point for the shielding rod 8 wrapped and connected to its outer surface. When the impact force is transmitted to the other side of the steel base 1, the second extension rod 9 shrinks to the inner side of the shielding rod 8. A shock-absorbing spring 10 is installed inside the first extension rod 7, and the tail end of the shock-absorbing spring 10 is connected to the inside of the second extension rod 9. When the impact force is transmitted to the inside of the first extension rod 7 and the second extension rod 9, the shock-absorbing spring 10 shrinks, converts the impact force into elastic potential energy, absorbs the impact force, and thus improves the stability of the diamond grinding wheel.
