Background
The grinding wheel is a tool which is used for carrying out large-batch forming grinding processing on parts with high efficiency and high precision. The dressing roller is a tool for grinding and shaping the grinding wheel. The ceramic grinding wheel is shaped and dressed through a dressing roller wheel arranged on a grinding machine, and parts are ground after the grinding wheel is shaped, so that the contour and the precision size of the dressing roller wheel are copied to the surface of the part to be machined through the grinding wheel.
Gears are important parts of transmission systems, and tooth profiles, tooth roots and the like also need to be ground by grinding wheels. The existing roller for dressing gears is divided into a plurality of types. The roller for trimming the involute profile of the tooth and the roller for trimming the tooth root are separately arranged, and the gear trimming needs two processes for separately trimming the tooth profile and the tooth root. Because the existing processing method is used for manufacturing a roller, interference is easily avoided during processing, the processing precision is influenced, and the gear which does not meet the requirement is caused. In addition, the cross section of the working surface of the roller for processing the involute is a triangular-like area, so that the roller is easy to wear, the service life of the roller is shortened after the roller is worn, and the existing method is that the top end and two sides of the top end of the triangle are provided with wear-resistant layers consisting of diamond particles, but the top end is still worn seriously, so that the service life of the roller needs to be further prolonged.

Detailed Description
As shown in fig. 1-3, a dressing roller for a gear comprises a first roller 1 and a second roller 2 which are assembled together and can be disassembled, wherein the first roller 1 and the second roller 2 are rotary bodies, and the axes of the first roller 1 and the second roller are overlapped after the first roller 1 and the second roller 2 are assembled. The first roller 1 comprises a first working surface 3 for grinding a corresponding standard involute tooth profile on a grinding wheel, and the second roller 2 comprises a second working surface 4 for grinding a corresponding tooth root on a grinding wheel. A layer of diamond particles is provided on the outer edges of the first and second working surfaces 3, 4. Therefore, the first roller 1 and the second roller 2 are separately processed, and the processing difficulty is reduced. The processing is completed and then the grinding wheel is assembled together, the involute tooth form and the tooth root of the corresponding grinding wheel can be processed simultaneously, the working procedure is saved, the processing working hour is reduced, and the cost is reduced.
The first roller 1 and the second roller 2 are detachably connected together by bolts. The first roller 1 and the second roller 2 are provided with countersunk threaded holes 10 along the circumference. Other connection means may of course be used.
