Technical Field

[0001] This utility model relates to the field of diamond roller technology, and in particular to a special diamond roller for chamfering. Background Technology

[0002] Diamond rollers are high-efficiency grinding wheel dressing tools used for mass production of profile grinding. They are widely used in the machining of precision parts in the automotive, aerospace, bearing, and gear industries. By dressing ordinary ceramic or CBN grinding wheels, diamond rollers replicate their own shape, precision, and dimensions onto the surface of the workpiece, thereby achieving high-precision and high-efficiency grinding.

[0003] Compared to traditional single-point diamond pens, diamond roller dressing significantly improves efficiency and ensures consistent processing accuracy.

[0004] Generally, diamond rollers are fixedly connected to the internal matrix. However, when the diamond particles wear out severely, the entire roller needs to be replaced. The internal matrix is ​​not easy to disassemble, and because it is not convenient to reuse the internal matrix, the operating cost is high. Summary of the Invention

[0005] The purpose of this invention is to provide a special diamond grinding wheel for chamfering, wherein the base ring is inserted into the interior of the fixing hole through a fixing rod to realize the connection between the base ring and the diamond ring body. This allows for the individual replacement of the worn outer diamond ring assembly, while the inner base ring assembly can be reused, reducing the cost of use and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a special diamond grinding and chamfering roller, comprising a diamond outer ring assembly, a base inner ring assembly detachably connected inside the diamond outer ring assembly, and encapsulation assemblies detachably connected to the left and right sides of the base inner ring assembly, wherein a fixing bolt is connected between the encapsulation assembly and the diamond outer ring assembly.

[0007] The diamond outer ring assembly includes a diamond ring body with a disc-shaped structure, and the diamond ring body has arc-shaped chamfers around its perimeter;

[0008] The inner ring assembly of the matrix includes a matrix ring detachably connected to the interior of the diamond ring, and a fixing rod passes through the interior of the matrix ring.

[0010] Preferably, the inner ring assembly of the matrix further includes a movable block fixed to one end of the fixed plug rod, and a connecting spring is fixed to the side of the movable block away from the fixed plug rod. The fixed plug rod is elastically connected to the matrix ring through the movable block and the connecting spring.

[0011] Preferably, the fixing rod is inserted into the interior of the fixing hole, and the front end of the base ring has a strip-shaped hole.

[0012] Preferably, the movable block has a limiting hole inside, and the encapsulation assembly includes an encapsulation plate disposed on the outside of the base ring, with a limiting rod fixed to the side of the encapsulation plate facing the base ring.

[0013] Preferably, the limiting rod passes through the interior of the limiting hole, and the size of the limiting rod is adapted to the size of the limiting hole. Rubber plugs are provided around the limiting rod, and the size of the rubber plugs is adapted to the size of the strip hole.

[0014] Preferably, the fixing bolts pass through the upper and lower sides inside the encapsulation plate, and the encapsulation plate is fixedly connected to the diamond ring body by the fixing bolts.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

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.

[0027] This utility model provides a technical solution:

[0028] Please see Figures 1 to 4 A special diamond grinding wheel includes a diamond outer ring assembly 1, a base inner ring assembly 2 detachably connected inside the diamond outer ring assembly 1, and encapsulation assemblies 3 detachably connected to the left and right sides of the base inner ring assembly 2, with fixing bolts 4 connecting the encapsulation assembly 3 and the diamond outer ring assembly 1.

[0029] The diamond outer ring assembly 1 includes a diamond ring body 101 with a disc-shaped structure. The diamond ring body 101 has an arc-shaped chamfer 102 around its perimeter. The diameter of the arc-shaped chamfer 102 is 0.6 mm with an error of ±0.02 mm.

[0030] The inner ring assembly 2 includes a base ring 201 that is detachably connected to the inside of the diamond ring 101, and a fixing rod 206 passes through the inside of the base ring 201.

[0031] The outer diamond ring assembly 1 also includes a plurality of equally spaced and uniformly distributed fixing holes 103 on the inner wall of the diamond ring body 101. Bolt connection holes 104 adapted to the fixing bolts 4 are provided on both the left and right sides of the diamond ring body 101. The inner ring assembly 2 also includes a movable block 202 fixed to one end of the fixing rod 206. A connecting spring 205 is fixed on the side of the movable block 202 away from the fixing rod 206. The fixing rod 206 is elastically connected to the base ring 201 through the movable block 202 and the connecting spring 205.

[0032] By adopting the above technical solution, the base ring 201 is installed inside the diamond ring body 101, and the fixed insert 206 is pressed inward. The fixed insert 206 can drive the movable block 202 to press the connecting spring 205 inward. At this time, the fixed insert 206 can enter the interior of the fixed insertion hole 103. Under the elastic action of the connecting spring 205, the movable block 202 can be pushed to move closer to the diamond ring body 101, and the base ring 201 is fixed inside the diamond ring body 101. By replacing the original diamond roller with a combination structure of the base inner ring assembly 2 and the diamond outer ring assembly 1, the base ring 201 is inserted into the interior of the fixed insertion hole 103 through the fixed insert 206, realizing the connection between the base ring 201 and the diamond ring body 101. The worn diamond outer ring assembly 1 can be replaced separately, while the inner base inner ring assembly 2 can be reused, reducing the cost of use.

[0033] Specifically, such as Figure 4 and Figure 5 As shown, the fixed insertion rod 206 is inserted into the fixed insertion hole 103. The front end of the base ring 201 is provided with a strip hole 203. The movable block 202 is provided with a limiting hole 204. The encapsulation assembly 3 includes an encapsulation plate 301 disposed on the outside of the base ring 201. The limiting insertion rod 303 is fixed on the side of the encapsulation plate 301 facing the base ring 201.

[0034] The limiting rod 303 passes through the interior of the limiting hole 204, and the size of the limiting rod 303 is adapted to the size of the limiting hole 204. Rubber plugs 302 are provided around the limiting rod 303, and the size of the rubber plugs 302 is adapted to the size of the strip hole 203. The fixing bolts 4 pass through the upper and lower sides of the encapsulation plate 301, and the encapsulation plate 301 is fixedly connected to the diamond ring 101 by the fixing bolts 4.

[0035] By adopting the above technical solution, after the base ring 201 is installed inside the diamond ring 101, the encapsulation plate 301 can be encapsulated on the base ring 201. The limiting rod 303 is inserted into the limiting hole 204. The limiting rod 303 can limit the position of the movable block 202, preventing the movable block 202 from moving due to vibration during the operation of the diamond roller. At the same time, the rubber plug 302 is inserted into the strip hole 203 to seal the strip hole 203. The fixing bolt 4 is threadedly connected to the bolt connection hole 104. Through the encapsulation component 3, the encapsulation plate 301 is inserted into the movable block 202 through the limiting rod 303. This not only limits the movable block 202 and connects the base ring 201, but also connects the diamond ring 101 through the fixing bolt 4, improving the connection stability between the diamond ring 101 and the base ring 201.

[0036] Working principle: The base ring 201 is installed inside the diamond ring 101, pressing the fixing rod 206 inward. The fixing rod 206 can drive the movable block 202 to press the connecting spring 205 inward. At this time, the fixing rod 206 can enter the interior of the fixing hole 103. Under the elastic action of the connecting spring 205, the movable block 202 can be pushed to move closer to the diamond ring 101, thus fixing the base ring 201 inside the diamond ring 101. The encapsulation plate 301 is then encapsulated on the base ring 201, limiting the movement. The insertion rod 303 is inserted into the limiting hole 204. The limiting insertion rod 303 can limit the position of the movable block 202 and prevent the movable block 202 from moving due to the vibration of the diamond roller during operation. At the same time, the rubber plug 302 is inserted into the strip hole 203 to seal the strip hole 203. The fixing bolt 4 is threadedly connected to the bolt connection hole 104. The limiting insertion rod 303 of the encapsulation plate 301 is inserted into the movable block 202 to limit the movable block 202. The diamond ring body 101 can be connected through the fixing bolt 4.
