The diamond polishing piece is symmetrically arranged on both sides of the base body. The fixed pin is arranged on both sides of the base body and extends into the diamond polishing piece. The outer side of the diamond polishing piece is provided with a diamond abrasive layer. A sleeve is concentrically arranged in the middle of the base body. A guide hole corresponding to the sleeve is arranged in the diamond polishing piece. A ring groove is arranged in the guide hole. A pin hole pointing to the ring groove is radially arranged in the sleeve. The movable pin is arranged in the pin hole and extends into the ring groove. The nest is arranged in the sleeve to limit the movable pin.

[0007] The outer circular end of the nest is provided with a radially extending connecting plate, and the end of the sleeve is concavely provided with a clamping groove corresponding to the connecting plate.

[0008] The connecting plate is provided with a stepped hole, and the stepped hole is provided with a screw connected with the sleeve.

[0009] The diamond grinding disc has a flange extending to the edge of the substrate to form a butterfly-shaped structure.

[0010] The edges of the diamond grinding discs on both sides are connected to cover the edge of the substrate.

[0011] The inner surface of the diamond grinding disc is provided with a positioning blind hole corresponding to the fixing pin.

[0012] The beneficial effects of this utility model are as follows: A high-precision diamond disc wheel for dressing grinding wheels has diamond grinding discs on both sides of the base that can be used individually for grinding wheel dressing, or both sides can be used simultaneously to expand the range of applications. It has good functionality, extends service life, and individual maintenance of the diamond grinding discs can reduce maintenance costs. The positioning and limiting of the diamond grinding discs are achieved through fixed pins and movable pins, ensuring assembly accuracy and stability during use. Moreover, no screws are required to install on the outer side of the diamond grinding discs, increasing the area that the diamond abrasive can cover and making it more widely applicable.

[0014] Figure 2 yes Figure 1 The right view;

[0015] Figure 3 yes Figure 1 Exploded view. Detailed Implementation

[0016] The following is combined Figures 1 to 3 The technical solution of this utility model will be further illustrated through specific embodiments.

[0017] like Figure 1 The high-precision diamond disc wheel for dressing shown includes: a base 8, a nest 7, a diamond grinding disc 2, a fixing pin 4, and a movable pin 6. The base 8 adopts a disc structure, and the diamond grinding discs 2 are symmetrically arranged on both sides of the base 8. A diamond abrasive layer 3 is provided on the outer surface of the diamond grinding disc 2, enabling double-sided grinding. It can be used on one side only and disassembled for replacement, extending its service life. The diamond abrasive layer 3 can be fixed to the outer surface of the diamond grinding disc 2 by brazing or electroplating, ensuring structural stability.

[0018] The fixing pins 4 are disposed on both sides of the base 8 and extend into the diamond grinding disc 2. In this embodiment, the inner surface of the diamond grinding disc 2 is provided with positioning blind holes 5 corresponding to the fixing pins 4. Through the cooperation of at least two sets of fixing pins 4 and positioning blind holes 5, the radial positioning of the diamond grinding disc 2 on the side of the base 8 is achieved, ensuring the concentricity of the diamond grinding disc 2 and the base 8. In addition, the positioning blind holes 5 ensure the integrity of the outer surface of the diamond grinding disc 2, eliminating the need for screws, increasing the area that the diamond abrasive 3 can cover, and making its application range wider.

[0019] A sleeve 1 is concentrically arranged in the middle of the base 8. The base 8, sleeve 1, and fixing pin 4 can be made of an integrated steel structure, which has high strength. The diamond grinding disc 2 is provided with a guide hole corresponding to the sleeve 1, which facilitates assembly and ensures assembly accuracy.

[0020] like Figure 3 As shown, an annular groove 12 is provided in the guide hole, and a pin hole 13 pointing to the annular groove 12 is provided radially in the sleeve 1. The movable pin 6 is provided in the pin hole 13 and extends into the annular groove 12, thereby realizing the axial positioning of the diamond grinding disc 2 on the side of the substrate 8 and ensuring positional accuracy and stability.

[0021] like Figure 1 and Figure 2 As shown, the nest 7 is positioned in the sleeve 1 to limit the movable pin 6, preventing the movable pin 6 from exiting the annular groove 12 and ensuring structural reliability. The outer circular end of the nest 7 is provided with a radially extending connecting plate 9, and the end of the sleeve 1 is recessed with a groove 11 corresponding to the connecting plate 9, ensuring the flatness of the end of the sleeve 1 after assembly.

[0022] A stepped hole is provided in the connecting plate 9, and a screw 10 is provided in the stepped hole to connect with the sleeve 1, thereby fixing the connecting plate 9. The connecting plate 9 is welded to the nest 7, thereby fixing the nest 7 and preventing it from loosening.

[0023] like Figure 3 As shown, a flange 14 extending to the edge of the substrate 8 is provided on the edge of the diamond grinding disc 2 to form a butterfly-shaped structure. The flanges 14 on both sides of the diamond grinding disc 2 are in contact with each other, covering the edge of the substrate 8, which helps to further increase the coverage area of ​​the diamond abrasive layer 3 and expand the functionality of the diamond grinding disc 2 for single-sided and double-sided use.
