[0001] The utility model relates to the technical field of grinding processing, in particular to a structure of a grinding wheel base assembly for interchangeability. Background Art

[0002] The grinding wheel is an important processing tool in the industrial grinding field. Among them, the superhard grinding wheel has high wear resistance due to the excellent physical and chemical properties of its abrasive, and can achieve higher-quality surface processing. The superhard grinding wheel is widely used in precision and ultra-precision machining and manufacturing scenarios. The superhard grinding wheel abrasive is made of artificial diamond or cubic boron nitride. Usually, the superhard grinding wheel consists of a grinding wheel base and a superhard abrasive layer bonded to the outer side of the grinding wheel base. Reserved mounting holes are processed on the grinding wheel base of the superhard grinding wheel, and it can be installed on a grinding machine through a grinding wheel chuck for grinding processing. However, due to the differences in the structures of different grinding machines, the sizes of the grinding wheel chucks are also different. Therefore, in order to adapt to different sizes of grinding wheel chucks, reserved mounting holes matching different sizes of grinding wheel chucks need to be added to the center of the grinding wheel base. In this way, the grinding wheel base cannot be interchanged and used universally among different grinding machines, bringing more costs and also consuming more production and manufacturing time. Content of the Utility Model

[0018] Embodiment: A structure of a grinding wheel base 2 assembly for interchangeability, comprising a grinding wheel abrasive layer 1, a grinding wheel base 2, an interchangeability assembly 3 and a connecting piece. The grinding wheel abrasive layer 1 is fixedly compounded on the outer circumference of the grinding wheel base 2. The interchangeability assembly 3 can be detachably and concentrically fixedly installed on the grinding wheel base 2 through the connecting piece. The inner hole of the interchangeability assembly 3 is a chuck mounting hole 4 for fixedly installing with the grinding wheel chuck of a grinding machine. The inner holes of different interchangeability assemblies 3 match the mounting dimensions of the grinding wheel chucks of different specifications of grinding machines.

[0019] When it is necessary to install the grinding wheel on grinding machines of different specifications, it is only necessary to disassemble the interchangeability assembly on the grinding wheel and replace it with an interchangeability assembly corresponding to the size of the grinding wheel chuck of the grinding machine. There is no need to replace the entire grinding wheel. One grinding wheel can cooperate with several interchangeability assemblies to cope with the installation of grinding machines of multiple specifications. When processing with grinding machines of different specifications, there is no need to prepare multiple grinding wheels with different chuck mounting holes 4. Only one standard grinding wheel and multiple interchangeability assemblies 3 of different specifications need to be prepared. When manufacturing the grinding wheel, there is no need to manufacture multiple specifications of grinding wheels with different chuck mounting holes 4. Only one specification of grinding wheel and multiple specifications of interchangeability assemblies 3 need to be manufactured. The manufacturing cost of the interchangeability assembly 3 is very low. Therefore, the cost of clamping the grinding wheel on grinding machines of different specifications is greatly reduced, enabling one grinding wheel to be interchangeable and universal for grinding machines of multiple specifications, achieving cost reduction and efficiency increase in the grinding wheel manufacturing process.

[0020] A T-shaped central hole with an inner diameter at one end larger than that at the other end is formed inside the grinding wheel base 2. The interchangeability assembly 3 is a T-shaped ring-columnar structure with an outer diameter at one end larger than that at the other end. The interchangeability assembly 3 is inserted into the T-shaped central hole of the grinding wheel base 2. The circumferential outer side surfaces at both ends of the interchangeability assembly 3 are closely attached to the circumferential inner side surfaces at both ends of the T-shaped central hole inside the grinding wheel base 2. The axial stepped surface formed between both ends of the interchangeability assembly 3 is closely attached to the stepped surface of the T-shaped central hole of the grinding wheel base 2.

[0021] Through the cooperation and insertion assembly of the T-shaped central hole and the T-shaped ring-columnar structure, automatic centering can be achieved, the assembly is fast, and it can ensure that the grinding wheel abrasive layer 1 and the chuck mounting hole 4 are coaxial after assembly.

[0022] The above structure can flexibly match different sizes of grinding wheel chucks of different grinding machines by replacing the interchangeability assembly 3. The relationship between the chuck mounting hole 4 of the grinding wheel, the size of the grinding wheel interchangeability assembly 3 and the inner hole of the grinding wheel base 2 is as follows:

[0023] c = a – 2×b;

[0024] Among them, a represents the inner hole dimension of the outer step of the grinding wheel base body 2, b represents the ring dimension of the inner step of the interchangeable component 3, and c represents the chuck mounting hole dimension of the grinding wheel after the grinding wheel base body 2 is installed.

[0025] In addition to the above structure, it is also possible to provide a countersunk through hole on the grinding wheel base body 2. The interchangeable component 3 is a cylindrical ring structure. The interchangeable component 3 is inserted into the countersunk head of the countersunk through hole of the grinding wheel mechanism. It is also possible to design the cross-section of the T-shaped central hole in the grinding wheel base body 2 as a square structure and design the interchangeable component 3 as a square column structure as well. Such are all equivalent replacement structures that are easily conceivable by those skilled in the art according to this application and all fall within the protection scope of this application.

[0026] A number of connecting through holes are formed on the inner step of the grinding wheel base body 2 at intervals along the circumferential direction of the grinding wheel base body 2. A number of threaded holes are formed on the outer step of the interchangeable component 3 at intervals along the circumferential direction of the interchangeable component 3. The connecting piece is a connecting bolt. The connecting bolts pass through the connecting through holes one by one and are screwed with the threaded holes. The head of the connecting bolt abuts against the other end of the grinding wheel base body 2. The grinding wheel base body 2 and the stepped part of the interchangeable component 3 are fixedly connected by the connecting bolts. The interchangeable component 3 is convenient to install and disassemble and can withstand large-torque grinding processing.

[0027] The connecting through holes on the grinding wheel base body 2 are countersunk through holes, and the heads of the connecting bolts are completely accommodated in the countersunk heads of the connecting through holes. By designing the connecting through holes as countersunk through hole structures, the heads of the connecting bolts are hidden in the countersunk heads of the connecting through holes to avoid interference between the heads of the connecting bolts and other components.

[0028] Six connecting through holes are arranged at uniform intervals along the circumferential direction of the grinding wheel base body 2 on the inner step of the grinding wheel base body 2. Six threaded holes are arranged at uniform intervals along the circumferential direction of the interchangeable component 3 on the outer step of the interchangeable component 3.

[0029] The above is a better solution. It can also be other numbers of connecting points, which can be designed according to actual processing requirements.

[0030] The plane at both axial ends of the interchangeable component 3 is aligned and joined with the plane at both axial ends of the grinding wheel base body 2. The design of alignment and joining enables the interchangeable component 3 and the grinding wheel base body 2 to form a perfect integral structure after assembly and avoids interference with other components.

[0031] The grinding wheel abrasive layer 1 is integrally formed on the circumferential outer side surface of the grinding wheel base body 2 by sintering.
