Description

Technical Field

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

[0002] Cycloidal diamond rollers are high-efficiency, long-life, and low-cost grinding wheel dressing tools used in mass production of profile grinding on specialized machine tools and gear grinding machines. By installing cycloidal diamond rollers on the dressing device of a grinding machine, the grinding wheel is processed using cycloidal diamond rollers, and then the profiled grinding wheel is used to grind the parts. In this way, the shape, contour, precision, and dimensions of the cycloidal diamond rollers are copied to the surface of the workpiece through the grinding wheel.

[0003] Ordinary roller structures cannot accurately replicate the complex curve shape of a cycloid, resulting in the manufactured parts failing to meet increasingly stringent industrial requirements in terms of tooth shape and contour accuracy. Moreover, during long-term dressing operations, high temperatures reduce the hardness and wear resistance of diamond particles, while increasing thermal stress, making diamond particles more prone to cracking, chipping, or even falling off, thus greatly reducing the service life of the roller. Utility Model Content

[0004] The main objective of this invention is to provide a cycloidal diamond roller to address the problem that conventional roller structures in related technologies struggle to accurately replicate the complex curves of a cycloid, resulting in parts that fail to meet increasingly stringent industrial requirements in terms of tooth profile and contour accuracy. Furthermore, during prolonged dressing operations, high temperatures reduce the hardness and wear resistance of diamond particles while increasing thermal stress, making the diamond particles more prone to cracking, chipping, or even detachment, thus significantly reducing the roller's lifespan.

[0005] To achieve the above objectives, according to one aspect of the present invention, a cycloidal diamond roller is provided, comprising a diamond roller housing, an upper protective cover fixedly connected to the upper end of the diamond roller housing, a lower protective cover fixedly connected to the lower end of the diamond roller housing, a rotating shaft coaxially connected to the upper and lower protective covers, and a spiral groove formed inside the diamond roller housing.

[0006] Furthermore, an inlet pipe is fixedly provided inside the upper protective cover, and an inlet interface is fixedly provided at the upper end of the inlet pipe.

[0007] Furthermore, a liquid outlet pipe is fixedly installed inside the lower protective cover.

[0008] Furthermore, the upper end of the outlet pipe is fixedly provided with an outlet port.

[0009] Furthermore, the lower end of the diamond roller housing is provided with a liquid inlet and a liquid inlet outlet.

[0010] Furthermore, the upper end of the diamond roller housing is provided with a liquid outlet pipe inlet and a liquid outlet pipe outlet.

[0011] Furthermore, a diamond roller body is fixedly installed inside the diamond roller housing, and the diamond roller body is coaxially connected to the rotating shaft.

[0012] Furthermore, a main spiral groove is formed inside the diamond roller body.

[0013] Furthermore, a number of diamond protrusions are fixedly provided on the outer shell of the diamond roller.

[0014] Furthermore, grooves are formed between the diamond protrusions.

[0015] Compared with the prior art, this utility model has the following beneficial effects: the cycloidal diamond roller can accurately replicate the cycloidal contour during the processing, ensuring that the contour accuracy of the processed parts reaches an extremely high level. By setting the outer shell spiral groove and the main body spiral groove, the coolant is continuously circulated from the inside, which solves the problem that the hardness and wear resistance of diamond particles will decrease due to high temperature during long-term dressing operations, and at the same time, the thermal stress will increase, making diamond particles more prone to cracking, chipping or even falling off, thereby greatly reducing the service life of the roller.

[0020] To further illustrate the technical means and effects adopted by the utility model in order to achieve the intended purpose of the utility model, the following detailed description of the specific implementation methods, structure, features and effects of the utility model, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0021] Please see Figures 1-3As shown, the purpose of this embodiment is to provide a cycloidal diamond roller, including a diamond roller housing 1, an upper protective cover 2 fixedly connected to the upper end of the diamond roller housing 1, a lower protective cover 3 fixedly connected to the lower end of the diamond roller housing 1, and a rotating shaft 4 coaxially connected to the upper protective cover 2 and the lower protective cover 3.

[0022] The diamond roller housing 1 has a housing spiral groove 15 inside, and the diamond roller body 5 is fixedly installed inside the diamond roller housing 1. The diamond roller body 5 is coaxially connected to the rotating shaft 4. The diamond roller body 5 has a main spiral groove 51 inside, and the housing spiral groove 15 and the main spiral groove 51 form a coolant channel.

[0023] It should be noted that the cross-sections of both the outer spiral groove 15 and the main spiral groove 51 are semicircular, and the diameters of the outer spiral groove 15 and the main spiral groove 51 are the same.

[0024] The upper protective cover 2 is fixedly provided with an inlet pipe 6, and the upper end of the inlet pipe 6 is fixedly provided with an inlet interface 61. The lower protective cover 3 is fixedly provided with an outlet pipe 7, and the upper end of the outlet pipe 7 is fixedly provided with an outlet interface 71. The coolant flows in the rotating shaft, enters the inlet pipe 6 through the inlet interface 61 and flows into the inlet pipe inlet 13, and enters the outlet interface 71 through the outlet pipe 7 and flows into the rotating shaft.

[0025] The lower end of the diamond roller housing 1 is provided with a liquid inlet pipe 13 and a liquid inlet pipe 14, and the upper end of the diamond roller housing 1 is provided with a liquid outlet pipe 16 and a liquid outlet pipe 17. The liquid inlet pipe 13, the liquid inlet pipe 14, the liquid outlet pipe 16, and the liquid outlet pipe 17 are used for the coolant to enter and exit within the diamond roller housing 1 and the diamond roller body 5.

[0026] The diamond roller shell 1 is fixedly provided with several diamond protrusions 11, and grooves 12 are opened between the diamond protrusions 11. The diamond roller body 5 is made of high-strength alloy steel, which has good rigidity and wear resistance and can withstand the large pressure and friction during the dressing process. The space between the diamond roller shell 1 and the diamond roller body 5 is filled with a cobalt-based alloy metal binder, which has strong adhesion and can firmly fix the diamond particles on the diamond roller body 5. At the same time, it also has a certain degree of self-lubrication, reducing frictional heat and wear during the dressing process.

[0027] In practical use, the coolant flows within the rotating shaft, entering the inlet pipe 6 through the inlet port 61 and flowing into the inlet pipe inlet 13. It then flows out from the inlet pipe outlet 14 and into the diamond roller housing 1. Through the spiral groove 15 of the housing and the spiral groove 51 of the main body, the coolant flows into the outlet pipe inlet 16 and out from the outlet pipe outlet 17, flowing into the outlet pipe 7. Finally, it flows into the rotating shaft through the outlet port 71 to achieve circulation. A cobalt-based alloy metal binder is filled between the diamond roller housing 1 and the diamond roller main body 5. This binder has strong adhesion, which can firmly fix the diamond particles onto the diamond roller main body 5. It also has a certain degree of self-lubrication, reducing frictional heat and wear during the dressing process.
