Description

Technical Field

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

[0002] Diamond rollers are high-precision machining tools. By mounting them on the dressing device of a grinding machine, diamond rollers dress ordinary ceramic grinding wheels or CBN grinding wheels. After the grinding wheels are shaped, the parts are ground, thereby replicating the shape, precision, and dimensions of the diamond rollers onto the surface of the workpiece.

[0003] RV reducers typically include core components such as cycloidal gears, pinwheels, and crankshafts. In the machining of these components, diamond rollers, with their high precision, high hardness, and excellent shape replication capabilities, can be applied to multiple key processes.

[0004] To adapt to different usage scenarios, diamond rollers are installed in different ways on the dressing device of a grinding machine. Among them, the method of fitting the diamond roller onto the drive shaft and clamping it with nuts and washers on both sides is more common and the installation structure is relatively simple.

[0005] However, after a period of high-speed grinding, the diamond roller installed using the above method may become loose. This not only poses a safety hazard but also affects normal grinding work. Furthermore, when the diamond roller is damaged and needs to be replaced after a period of use, the entire roller needs to be replaced and discarded, which undoubtedly increases the cost of use. Utility Model Content

[0006] The purpose of this invention is to solve the problems in the prior art where diamond rollers may loosen after a period of use and need to be discarded when damaged, and to propose a new type of diamond roller.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A diamond roller includes a roller body with a connecting hole at the central shaft. A first side clamp and a second side clamp are detachably connected to both sides of the roller body. A connecting cylinder passing through the connecting hole is fixed in the middle of the first side clamp. A fastening assembly is provided on the outside of the connecting cylinder to increase the friction between the connecting cylinder and the roller body, and between the connecting cylinder and the drive shaft of an external dressing device. A disassembly and assembly assembly for connecting the roller body is provided between the first side clamp and the second side clamp.

[0009] In some embodiments, the fastening assembly includes a connecting ring and a clamping assembly. The connecting ring is sleeved and fixed to the outside of the connecting cylinder, and the clamping assembly is located inside the connecting ring and connected to the connecting hole and the drive shaft of the grinding machine dressing device, respectively.

[0010] In some embodiments, the compression assembly includes an airbag ring, top blocks, and a compression mechanism. The number of top blocks is several and they are connected to the outside of the airbag ring. The top blocks are divided into two groups and are slidably connected to the connecting ring and the connecting cylinder, respectively.

[0011] In some embodiments, the extrusion mechanism includes an extrusion plate and an extrusion rod. The extrusion plate is slidably connected within the connecting ring and is used to extrude the airbag ring. The extrusion rod is fixed to the extrusion plate and extends outward to the outside of the first side clamp.

[0012] In some embodiments, the disassembly and assembly assembly includes a plurality of bolts and a limiting post, wherein the plurality of bolts are connected between the first side clamp and the second side clamp, and the limiting post is fixed to the first side clamp and inserted into the roller body.

[0013] In some embodiments, there are several limiting posts with through holes inside, and several bolts are inserted into the several through holes respectively.

[0014] In some embodiments, the outer surface of the second side clamp is provided with an insertion hole adapted to the limiting post, and the end of the limiting post away from the first side clamp is inserted into the insertion hole.

[0015] In some embodiments, anti-slip textures are provided on the opposite side of the first side clamp and the second side clamp to increase the friction between the roller body and the first side clamp and the second side clamp respectively.

[0016] Compared with the prior art, the present invention provides a diamond roller with the following beneficial effects.

[0017] 1. This utility model, through the setting of fastening components, can effectively improve the installation stability of the roller body and the entire diamond roller, thereby effectively preventing the diamond roller from loosening after a period of use, thus reducing the safety hazards during the high-speed rotation of the diamond roller, while ensuring the normal processing and production of the diamond roller.

[0018] 2. This utility model, through the cooperative arrangement of the first side clamping plate, the second side clamping plate and the disassembly and assembly components, allows only the roller body, the main processing component of the diamond roller, to be replaced when it is damaged. Other related components can continue to be used without replacing and discarding the entire diamond roller. This avoids excessive waste of materials and saves on usage costs to a certain extent.

[0019] 3. In this utility model, by setting a limiting post, after the bolt connects the roller body, the first side clamping plate and the second side clamping plate, the bolt is located in the through hole on the limiting post, thereby avoiding direct contact between the bolt and the roller body. Therefore, it can prevent the roller body from causing certain shearing and squeezing on the bolt surface during high-speed rotation, avoid affecting the disassembly and assembly of the bolt, and ensure the service life of related components. At the same time, the limiting post plays a positioning role when installing the second side clamping plate, making the assembly process more convenient, simple and easy to operate.

[0020] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Reference Figure 1 and Figure 2 A diamond roller includes a roller body 1. A connecting hole 101 is provided at the central shaft of the roller body 1. A first side clamping plate 2 and a second side clamping plate 3 are detachably connected to both sides of the roller body 1. A connecting cylinder 4 passing through the connecting hole 101 is fixed in the middle of the first side clamping plate 2. A fastening component 9 is provided on the outside of the connecting cylinder 4 to increase the friction between the connecting cylinder 4 and the roller body 1 and between the connecting cylinder 4 and the drive shaft 13 of the external dressing device. A disassembly and assembly component 7 connected to the roller body 1 is provided between the first side clamping plate 2 and the second side clamping plate 3.

[0032] Reference Figures 2 to 5 The fastening assembly 9 includes a connecting ring 5 and a clamping assembly 6. The connecting ring 5 is sleeved and fixed to the outside of the connecting cylinder 4. The outer diameter of the connecting ring 5 is the same as the inner diameter of the connecting hole 101. A cavity 501 is provided inside the connecting ring 5. The clamping assembly 6 is located inside the cavity 501 and is connected to the connecting hole 101 and the drive shaft 13 of the grinding machine dressing device. The cavity 501 has an opening on one side of the connecting ring 5 to facilitate the replacement of the damaged clamping assembly 6 and improve the convenience of maintenance.

[0033] The compression assembly 6 includes an airbag ring 601, top blocks 602, and a compression mechanism 603. There are several top blocks 602, which are divided into two groups. One group of top blocks 602 is fixed to the outer circular surface of the airbag ring 601, and the other group of top blocks 602 is fixed to the inner circular surface of the airbag ring 601. The outer surface of the connecting ring 5 has a first through groove 502 that communicates with the cavity 501. The top blocks 602 located on the outer circular surface of the airbag ring 601 are slidably connected to the first through groove 502. The outer surface of the connecting cylinder 4 has a second through groove 401 that communicates with its inner hole. The top blocks 602 located on the inner circular surface of the airbag ring 601 are slidably connected to the second through groove 401.

[0034] Reference Figures 3 to 6 The extrusion mechanism 603 includes an extrusion plate 6031 and an extrusion rod 6032. The extrusion plate 6031 is slidably connected to the connecting ring 5 and is used to extrude the airbag ring 601. The extrusion rod 6032 is fixed on the extrusion plate 6031 and extends outward to the outside of the first side clamping plate 2 and contacts the outer pad 11. The extrusion rods 6032 are set as several evenly distributed ones. At the same time, the extrusion plate 6031 is annular, which can ensure uniform extrusion of the airbag ring 601, thereby ensuring its service life.

[0035] Reference Figure 3 and Figure 4 The disassembly and assembly component 7 includes several bolts 701 and limiting posts 702. Several bolts 701 are connected between the first side clamping plate 2 and the second side clamping plate 3. Specifically, the bolts 701 are internal hexagon anti-loosening bolts, and the second side clamping plate 3 is provided with threaded holes 301 that are compatible with the bolts 701. The bolts 701 are threadedly connected to the threaded holes 301 by passing through the first side clamping plate 2.

[0036] There are several limiting posts 702 and through holes 7021 are provided inside. Several bolts 701 are inserted into several through holes 7021 respectively. Moreover, several limiting holes 102 adapted to the limiting posts 702 are provided on the roller body 1. Several limiting posts 702 are inserted into the limiting holes 102 respectively.

[0037] The outer surface of the second side clamping plate 3 is provided with an insertion hole 302 that is compatible with the limiting post 702. The insertion hole 302 is connected to the threaded hole 301, and the end of the limiting post 702 away from the first side clamping plate 2 is inserted into the insertion hole 302.

[0038] The second side clamping plate 3 has a first mounting hole 303 with the same outer diameter as the connecting cylinder 4 in the middle. The second side clamping plate 3 is sleeved on the end of the connecting cylinder 4 through the first mounting hole 303, and the diamond roller can be installed on the drive shaft 13 of the external dressing device through the inner hole of the connecting cylinder 4.

[0039] Reference Figure 3 and Figure 7 The first side plate 2 and the second side plate 3 are provided with anti-slip texture 10 on the opposite side to increase the friction between the roller body 1 and the first side plate 2 and the second side plate 3 respectively.

[0040] In this utility model, in the disassembled state, as follows Figure 2 As shown, when assembly is required, firstly, the roller body 1 is fitted onto the outside of the connecting ring 5 through the connecting hole 101. During this process, ensure that the limiting hole 102 on the roller body 1 is fitted onto the limiting post 702. At this time, the first side clamp 2 is attached to the front of the roller body 1, and then the second side clamp 3 is attached to the back of the roller body 1 and fitted onto the end of the connecting cylinder 4 through the first mounting hole 303. At the same time, ensure that the insertion hole 302 is fitted onto the end of the limiting post 702 to achieve positioning. Then, the bolt 701 is passed through the through hole 7021 and threaded into the threaded hole 301 on the second side clamp 3 until the bolt 701 is tightened to complete the assembly of the diamond roller.

[0041] When installing the diamond roller on the drive shaft 13 of the external dressing device, first install a set of nuts 12 and washers 11 on the drive shaft 13. Then, the roller body 1 can be directly sleeved on the outside of the drive shaft 13 through the inner hole of the connecting cylinder 4 until the diamond roller contacts the washers 11 that were previously installed on the drive shaft 13. Then, another washer 11 and another nut 12 are installed, and the diamond roller is clamped and fixed on the drive shaft 13 by tightening the nut 12.

[0042] During the tightening of nut 12, one of the pads 11 can push the pressing rod 6032 to slide by squeezing until the pressing rod 6032 is completely pushed into the first side clamping plate 2, as shown in the following... Figure 6 As shown, the sliding of the extrusion rod 6032 can compress the airbag ring 601 through the extrusion plate 6031, causing it to expand and deform radially. During this process, the outer diameter of the airbag ring 601 increases and the inner diameter decreases, thus pushing the top block 602 on the outer circular surface of the airbag ring 601 to press tightly against the inner wall of the connecting hole 101, thereby increasing the friction between the roller body 1 and the connecting ring 5, and thus improving the installation stability of the roller body 1. At the same time, it can also push the top block 602 on the inner circular surface of the airbag ring 601 to press tightly against the outer surface of the drive shaft 13, thereby increasing the friction between the connecting cylinder 4 and the drive shaft 13, thus effectively improving the installation stability of the entire diamond roller, and thus effectively preventing the diamond roller from loosening after a period of use, and also effectively preventing the roller body 1 from loosening.

[0043] When the roller body 1 needs to be replaced, first remove the diamond roller from the drive shaft 13, then unscrew the bolt 701 on the first side clamp 2 to separate the first side clamp 2 from the second side clamp 3, and thus remove the roller body 1. After replacing the roller body 1 with a new one, reinstall the first side clamp 2, the second side clamp 3, and the bolt 701 in their original positions. Thus, when the main processing component of the diamond roller, the roller body 1, is damaged, only the roller body 1 needs to be replaced, and other related components can continue to be used. It is not necessary to replace and scrap the entire diamond roller, thereby avoiding excessive waste of materials and saving operating costs to a certain extent.
