Description

Technical Field

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

[0002] Dressing rollers are tools used to shape grinding wheels. Diamond dressing rollers are dressing rollers made of diamond. They are high-efficiency, long-life, and low-cost grinding wheel dressing tools used in mass production of shaping grinding on specialized machine tools and gear grinding machines. By being installed on the dressing device of a grinding machine, diamond rollers dress ordinary ceramic grinding wheels or CBN grinding wheels. After the grinding wheel is shaped, the parts are ground, thereby replicating the shape, precision, and dimensions of the diamond roller onto the surface of the workpiece.

[0003] Diamond dressing rollers generate a large amount of heat during grinding. If this heat cannot be dissipated in time, it will affect the surface quality of the workpiece. The heat dissipation performance of the diamond dressing roller determines the grinding quality. For example, Chinese utility model patent CN221735845U can improve the heat dissipation effect of the diamond dressing roller and ensure its grinding quality by using the cooperation between heat dissipation holes, air inlet pipe and groove. During the high-speed rotation of the roller, the external air can flow in the heat dissipation holes and carry away the heat inside the roller. However, since the external air temperature is difficult to guarantee and the heat points of the diamond dressing roller are mainly concentrated in the outer area, it is difficult to guarantee the heat dissipation effect when using the through hole in the middle to allow the flow of external air to dissipate heat from the diamond dressing roller. In view of this, we propose a diamond dressing roller. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0025] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0026] Please see Figure 1-4This utility model provides a technical solution: a diamond dressing roller, including a drive shaft 1, a connecting shaft 2 sleeved on the outer surface of the drive shaft 1, a diamond dressing roller 3 sleeved on the outer surface of the connecting shaft 2, storage boxes 4 fixedly connected to the left and right sides of the diamond dressing roller 3, connecting rings 5 ​​fixedly connected to the side surfaces of the two storage boxes 4 that are far apart from each other, fan blades 6 fixedly connected to the outer surface of the connecting rings 5, and fixing rings 7 fixedly connected to the side surfaces of the fan blades 6 that are far apart from the connecting rings 5. Each of the two storage boxes 4 has a storage cavity 8 inside, and each of the two storage boxes 4 is equipped with a cooling component. The liquid nitrogen inside the two storage boxes 4 can cool the air when the outside air enters the diamond dressing roller 3 through the cooling component, thereby improving the cooling effect. The mirrored arrangement of the two storage boxes 4 ensures that cooling can still be performed when processing bidirectional dressing.

[0027] Furthermore, the cooling assembly includes a through pipe 9, which is fixedly connected to the inner wall of the storage box 4. The ends of the two through pipes 9, located far apart from each other, extend through the surfaces of the two storage boxes 4 on opposite sides. A cooling chamber 10 is formed inside the diamond dressing roller 3. The ends of the two through pipes 9, located close to each other, both extend into the cooling chamber 10. A guide ring 11 is fixedly connected to the inner wall of the cooling chamber 10. The guide ring 11 has a trapezoidal cross-section. A dispersion plate 12 is fixedly connected between the inner wall of the cooling chamber 10 and the outer surface of the guide ring 11. The drive shaft 1 has a through hole 13, which is inclined. The two storage boxes 4 are provided with a liquid injection valve 14 and a pressure relief valve 15 on the side surfaces that are far apart from each other. The outer surface of the drive shaft 1 is fixedly connected with a connecting key 16. The inner wall of the connecting shaft 2 is provided with a keyway 17 that matches the connecting key 16. By using the two dispersion plates 12 in conjunction with the through hole 13, the residence time of cold air in the cooling chamber 10 can be greatly increased, thereby increasing the cooling effect. At the same time, it can reduce the risk of injury to personnel caused by the cold air flowing out at too low a temperature.

[0028] Liquid nitrogen can be injected into the storage chamber 8 to cool the air inside the pipe 9, while the storage box 4 is made of austenitic stainless steel to prevent microcracks caused by temperature stress.

[0029] Working principle: When using the diamond dressing roller 3, liquid nitrogen is first injected into the storage tank 4 on one side through the injection valve 14. The storage tank 4 is selected according to the rotation direction of the diamond dressing roller 3. When the diamond dressing roller 3 rotates, the fan blades 6 guide the air on one side through the pipe 9 into the cooling chamber 10. At the same time, when the air flows through the pipe 9 into the storage chamber 8, the liquid nitrogen in the storage chamber 8 rapidly cools the air inside the pipe 9. The cooled air then enters the cooling chamber 10. The cool air is guided by the guide ring 11 and comes into contact with the dispersion plate 12. The cold air is dispersed into multiple streams through the through holes 13 on the dispersion plate 12, thereby making the cooling more uniform. The cold air absorbs the heat of the diamond dressing roller 3 itself by contacting the inner wall of the cooling chamber 10 through the through holes 13. Then, this cold air enters the interior of the through pipe 9 on the other side through the dispersion plate 12 on the other side, and is finally discharged through the through pipe 9. Since the interior of the discharge side storage box 4 is not equipped with liquid nitrogen, it can prevent the low temperature air from causing damage to the surrounding staff and reduce resource consumption.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
