[0002] The process of obtaining the specific structure and precision of gears by mechanical methods is gear forming processing. Diamond rollers are often required for gear processing. Diamond rollers are high-efficiency, long-life, and low-cost grinding wheel dressing tools for special machine tools for mass production forming grinding and gear grinders. When the existing diamond rollers are in use, they inevitably vibrate, which easily affects the use of diamond rollers. At the same time, it is rather cumbersome, time-consuming, and laborious to install the diamond cutting ring of the diamond roller.

A limiting component is arranged inside the diamond roller main body, an installation component is arranged outside the diamond roller main body, and two through holes are opened inside the diamond roller main body. The two through holes are symmetrically arranged on the upper and lower sides of the horizontal center line of the diamond roller main body.

[0004] In the above technology, the rotation of the limiting screw is facilitated through the threaded seat, which is convenient for driving the four clamping plates to move towards each other and clamp with the fixing device respectively between the four friction pads. However, the composition structure of the clamping plates is relatively single. Since the extrusion force of the clamping plates is required to clamp with the device, depressions will appear on the surface of the clamping plates after being subjected to external forces for a long time. The internal performance of the clamping plates needs to be strengthened, and the heat generated during the operation of the diamond roller will be transferred to the surface of the clamping plates, and the heat dissipation area is small. Therefore, innovation is made on this technology. Summary of the Utility Model

[0022] Please refer to Figures 1-4 , the present invention provides a technical solution for a diamond roller for gear forming:

[0023] Embodiment 1:

[0024] As Figures 1-3 shown, a diamond roller for gear forming includes a diamond roller body 1, a cutting ring 2, a plurality of twisting rods 3, a plurality of clamping rings 4 and a plurality of rubber pads 5. The cutting ring 2 is sleeved on one end of the diamond roller body 1. A plurality of twisting rods 3 are respectively arranged inside the diamond roller body 1. One side of each of the plurality of clamping rings 4 is connected to one end of each of the plurality of twisting rods 3.

The sound-absorbing layer 12 is made of polyurethane foam and has good sound-absorbing characteristics, which can be used to reduce the noise during the operation of the diamond roller body 1. The compressive layer 15 is made of carbon fiber material and can be used for high-strength components of the diamond roller, extending the service life of the diamond roller.

[0025] Embodiment 2:

[0026] On the basis of Embodiment 1, as Figure 1 and Figure 4 shown, filling layers 13 are arranged inside the plurality of clamping rings 4. The thicknesses of the plurality of sound-absorbing layers 12 are all smaller than the thicknesses of the plurality of filling layers 13. A plurality of through holes 16 are opened on one side of the diamond roller body 1. One side of a part of the flame-retardant layers 14 is in contact with one side of the plurality of compressive layers 15 respectively. For the diamond roller for gear forming of the present invention, by setting the wear-resistant layer 11, the filling layer 13, the flame-retardant layer 14 and the through holes 16, the wear-resistant layer 11 is made of silicon carbide material, enhancing the strength of the clamping ring 4, thereby improving the firmness of clamping between the diamond roller and the equipment. The flame-retardant layer 14 is made of alumina.

[0027] Working principle: The process of obtaining a specific structure and precision of gears by mechanical methods is gear forming machining. Diamond rollers are often indispensable in gear machining. Diamond rollers are high-efficiency, long-life, and low-cost grinding wheel dressing tools for special machine tools for mass production forming grinding and gear grinders. When existing diamond rollers are in use, they inevitably vibrate, which easily affects their use. By rotating the twisting rod 3, the positions of the clamping ring 4 and the rubber pad 5 can be adjusted. The rubber pad 5 can be clamped with the outer wall of the fixed device. Therefore, the diamond roller body 1 can be firmly installed with the device. Then, one side of each of the two reinforcing rings 6 is respectively attached to both sides of the diamond roller body 1. By using the threaded connection of multiple positioning rods 8 and positioning holes 9, the diamond roller body 1 and the reinforcing rings 6 can be limited and fixed. The heat conducting ring 10 is made of nickel alloy and can transfer the heat on the surface of the clamping ring 4 to itself, thereby increasing the heat dissipation area of the diamond roller body 1. The two heat conducting rings 10 are located outside the rubber pad 5. By the heat conducting rings 10 resisting the rubber pad 5 and the clamping ring 4, the stability of the clamping ring 4 clamping the device can be enhanced. The sound-absorbing layer 12 is made of polyurethane foam and has good sound-absorbing characteristics, which can be used to reduce the noise during the operation of the diamond roller body 1. The compressive layer 15 is made of carbon fiber material and can be used for high-strength components of the diamond roller, extending the service life of the diamond roller. The wear-resistant layer 11 is made of silicon carbide material, enhancing the strength of the clamping ring 4, thereby improving the firmness of clamping between the diamond roller and the device. The flame-retardant layer 14 is made of alumina and has good high-temperature resistance and fire resistance, enhancing the flame-retardant performance of the diamond roller and the clamping ring 4. The filling layer 13 is made of steel material, providing strength and stability. The through holes 16 can provide more heat transfer paths, enabling the diamond roller body 1 to more effectively transfer heat from the heat source to the surrounding environment.
