Description

Cycloidal diamond roller Technical Field The utility model relates to the technical field of machining tools, in particular to a cycloidal diamond roller. Background The cycloidal diamond roller is a high-efficiency, long-service-life and low-cost grinding wheel dressing tool for processing by a special machine tool for large-scale forming grinding and a gear grinding machine, is arranged on a dressing device of the grinding machine, is used for processing a grinding wheel, and is used for grinding a part, so that the outline, the precision and the size of the cycloidal diamond roller are copied to the surface of the processed part through the grinding wheel; The common roller structure is difficult to accurately reproduce the complex curve shape of cycloid, so that the processed parts are difficult to meet the increasingly higher industrial requirements in the aspects of tooth shape, contour precision and the like, in addition, the hardness and wear resistance of diamond particles can be reduced at high temperature in the long-time finishing operation process, and meanwhile, the thermal stress is increased, so that the diamond particles are easier to crack, break and even fall off, thereby greatly reducing the service life of the roller. Disclosure of utility model The utility model mainly aims to provide a cycloidal diamond roller, which aims to solve the problem that a common roller structure is difficult to accurately reproduce the complex curve shape of cycloid in the related technology, so that the processed part is difficult to meet the increasingly-improved industrial requirements in the aspects of tooth shape, contour precision and the like. In addition, in the long-time finishing operation process, the high temperature can reduce the hardness and the wear resistance of the diamond particles, and meanwhile, the thermal stress is increased, so that the diamond particles are easier to crack, break and even fall off, and the service life of the roller is greatly reduced. In order to achieve the above object, according to one aspect of the present utility model, there is provided a cycloidal diamond roller, including a diamond roller shell, an upper protecting cover is fixedly connected to an upper end of the diamond roller shell, a lower protecting cover is fixedly connected to a lower end of the diamond roller shell, the upper protecting cover and the lower protecting cover are coaxially connected to a rotation shaft, and a shell spiral groove is formed in the diamond roller shell. Further, the upper protective cover is internally and fixedly provided with a liquid inlet pipe, and the upper end of the liquid inlet pipe is fixedly provided with a liquid inlet port. Further, the lower protective cover is internally fixedly provided with a liquid outlet pipe. Further, a liquid outlet port is fixedly arranged at the upper end of the liquid outlet pipe. Further, the lower end of the diamond roller shell is provided with a liquid inlet pipe inlet and a liquid inlet pipe outlet. Further, a liquid outlet pipe inlet and a liquid outlet pipe outlet are formed in the upper end of the diamond roller shell. Further, a diamond roller body is fixedly arranged in the diamond roller shell, and the diamond roller body is coaxially connected with the rotating shaft. Further, a main body spiral groove body is arranged in the diamond roller main body. Further, a plurality of diamond bulges are fixedly arranged on the diamond roller shell. Further, grooves are formed between the diamond protrusions. Compared with the prior art, the cycloidal diamond roller has the advantages that the cycloidal diamond roller can accurately copy the cycloidal profile in the processing process, the profile precision of the processed part is ensured to reach an extremely high level, and through arranging the shell spiral groove body and the main body spiral groove body, cooling liquid is continuously circulated from the inside, so that the problems that the hardness and the wear resistance of diamond particles are reduced due to high temperature and the thermal stress is increased in the long-time trimming operation process, and the diamond particles are easier to crack, break and even fall off are solved, so that the service life of the roller is greatly reduced.
