[0003] As a forming and finishing tool roller, the diamond roller is gradually recognized by the market for its excellent properties of high hardness and long life made of diamond material, and has been widely used. During the production and use of the rack, a diamond roller needs to be used for grinding. In the prior art, the patent document with application number 202022252353.4 discloses a diamond roller for rack processing, comprising a roller body and a hollow cavity, a hollow cavity is provided at the middle position of the roller body, a heat dissipation structure is provided on both sides of the roller body, an anti-dislocation structure is provided around the hollow cavity, a processing structure is provided on the outside of the roller body, and the processing structure includes a first grinding part, the first grinding part is provided on one side of the outside of the roller body, a second grinding part is provided on the other side of the first grinding part, and a third grinding part is provided on the other side of the second grinding part. The above technical solution is equipped with three grinding parts. Compared with the traditional diamond roller for rack processing, which can only process one tooth groove of the rack at a time, it improves the work efficiency accordingly and is suitable for grinding large racks. However, when one of the three grinding parts of this solution is damaged, the entire diamond roller needs to be replaced, which easily causes waste and increases the cost of use. Summary of the Invention

[0004] The purpose of the utility model is to solve the problem in the prior art that when one of the grinding parts is damaged, the entire diamond roller needs to be replaced, which easily causes waste and increases the cost of use. A large rack diamond roller is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A large rack diamond roller comprises a mounting shaft and a roller body mounted on the middle of the mounting shaft, a fixing assembly being provided on one side of the roller body, the roller body comprising a disc-shaped wheel body and a plurality of bosses evenly distributed on the outside of the wheel body, an annular groove being provided on the outside of each boss, a group of arc-shaped grinding parts being installed in each annular groove, each group of the grinding parts being arranged as two pieces symmetrically distributed in the annular groove and fitted together, a positioning assembly being provided on the part of the grinding part located in the annular groove and cooperating with the boss, and by providing the positioning assembly, a function of quick assembly is achieved between the wheel body and the arc-shaped grinding part.

[0007] In some embodiments, the mounting shaft is a three-section stepped shaft with increasing diameter from left to right, namely the first section shaft, the second section shaft and the third section shaft. The first section shaft and the third section shaft are circular shafts, and the second section shaft is a regular square prism.

[0008] In some embodiments, the fixing assembly is located on the side of the roller body away from the third section of the shaft. The fixing assembly includes a retaining ring sleeved on the second section of the shaft and two bolts symmetrically arranged on the outside of the retaining ring. The two bolts are located on the same axis.

[0009] In some embodiments, a threaded hole cooperating with a bolt is provided on the outer side of the retaining ring.

[0010] In some embodiments, the center of the roller body and the retaining ring are both provided with a square hole that matches the second section of the shaft.

[0011] In some embodiments, the positioning assembly includes a mounting groove opened on one side of the grinding part and two springs arranged in the mounting groove. One end of the two springs is commonly connected to a clamping block, and the clamping block includes a large diameter section and a small diameter section. The large diameter section is connected to the spring, and the large diameter section is located in the mounting groove. A clamping hole matching the small diameter section is opened on the boss, and the two grinding parts are assembled to the wheel body through the mutual engagement of the clamping block and the clamping hole.

[0012] In some embodiments, at least two groups of grinding parts are arranged at equal intervals along the axis direction of the roller body. The distance between two adjacent groups of grinding parts is equal to the distance between two adjacent teeth on the rack. Three groups of tooth grooves can be ground at the same time, which correspondingly improves processing efficiency.

[0013] Compared with the prior art, the present invention provides a large rack diamond roller with the following beneficial effects.

[0014] The utility model sets a fixing component, first installs the roller body and the grinding part, then installs the retaining ring, and finally fixes the retaining ring by bolts, and then the grinding part can be driven to rotate by rotating the mounting shaft, thereby realizing the grinding demand for large racks; and, the part of the grinding part located in the annular groove is provided with a positioning component that cooperates with the boss. When the grinding part needs to be replaced, the clamping block is pressed to squeeze the spring to shrink toward the inside of the mounting groove, releasing the clamping state between the clamping block and the clamping hole, further enabling the grinding part to be separated from the clamping hole, making it convenient to replace the grinding part, and a single group of damaged parts can be replaced without replacing the entire diamond roller, thereby reducing the replacement cost accordingly.

[0015] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model improves the existing large rack diamond roller structure and avoids the waste of resources caused by replacing the entire diamond roller by setting a grinding part with a two-piece assembled structure.

[0016] Other advantages, objectives and features of the present invention will be described in the following description to some extent; and will be apparent to those skilled in the art based on an examination of the following; or may be taught from the practice of the present invention to some extent.
