Description

Technical Field

[0001] The utility model relates to the technical field of grinding wheels, in particular to a combined grinding wheel for cutting and grinding. Background Art

[0002] Grinding wheel is the most important type of grinding tool in grinding process. Grinding wheel is a porous body made by adding binder to abrasive, pressing, drying and baking. Due to the difference of abrasive, binder and manufacturing process, the characteristics of grinding wheel vary greatly, which has a great influence on the processing quality, productivity and economy of grinding. The characteristics of grinding wheel are mainly determined by factors such as abrasive, particle size, binder, hardness, structure, shape and size.

[0003] After searching, the Chinese patent application No. 202223189899.5 discloses a dual-purpose cutting and grinding grinding wheel.

The dual-purpose cutting and grinding grinding wheel provided by the patent is not only convenient for grinding and cutting, but also has high structural strength, simple and practical structural design.

[0004] Although the above patent is not only convenient for grinding and cutting, but also has high structural strength, simple and practical structural design, in actual use, due to the long-term use of the grinding wheel, its grinding base and cutting abrasive ring are easily worn, so it is necessary to replace them. At this time, due to the different frequencies and times of use of the grinding base or the cutting abrasive ring, the degree of wear is also different. The cutting and grinding dual-purpose grinding wheel in the above patent is an integral whole, and the grinding base and the cutting abrasive ring cannot be replaced separately, so that when the grinding base or the cutting abrasive ring is replaced, the entire cutting and grinding dual-purpose grinding wheel needs to be replaced together, thereby causing unnecessary waste of resources and increased use costs, which is not conducive to daily use by staff.

[0005] Therefore, it is necessary to modify the cutting and grinding dual-purpose grinding wheel in the above patent to effectively prevent the grinding base and the cutting abrasive ring from being integrated as a whole, which makes it impossible to replace them separately, thereby causing unnecessary waste of resources and increased use costs.

[0025] refer to Figure 4 A plurality of fixing grooves 16 are provided on one side of the mounting ring 8 close to the cutting ring 6 , and the plurality of fixing grooves 16 correspond to and are clamped with the plurality of guide posts 5 .

[0026] As a technical optimization solution of the utility model, by setting a plurality of fixing grooves 16, the mounting ring 8 can press the cutting ring 6 tightly, thereby preventing it from shaking during the cutting process, thereby improving the stability of the cutting ring 6 when in use.

[0027] refer to Figure 1 , the thickness of the grinding disc 14 is higher than the height of the mounting ring 8 .

[0028] As a technical optimization solution of the present invention, by setting the thickness of the grinding disc 14 higher than the height of the mounting ring 8, the grinding surface of the grinding disc 14 can be exposed, making the grinding direction more comprehensive.

[0029] refer to Figure 1 and Figure 6 A plurality of gasket rings 17 are arranged inside the connecting disc 1 , and the plurality of gasket rings 17 are stacked and used in conjunction with the grinding disc 14 .

[0030] As a technical optimization solution of the present invention, by providing a plurality of spacer rings 17 , the grinding disc 14 can be gradually raised as the effect thereof increases, thereby making the grinding disc 14 usable to the maximum extent.

[0035] The working principle and use process of the utility model are as follows: when the combined grinding wheel for cutting and grinding is used, firstly, the guide hole 7 on the cutting ring 6 is aligned with the guide column 5 on the connecting disk 1 and slid in, then the positioning block 9 on the mounting ring 8 is aligned with the positioning groove 3 and snapped in, at this time, the fixing groove 16 on the mounting ring 8 is snapped with the guide column 5, the positioning hole 4 is aligned with the fixing hole 10, and then the positioning hole 4 is positioned with the fixing hole 10 by an external bolt, thereby completing the installation of the cutting ring 6, and then according to the thickness specification of the grinding disk 14, it is selected whether to add the shim ring 17, that is, if the thickness of the grinding disk 14 is thin, the shim ring 17 can be added to increase the height of the grinding disk 14, so that the grinding disk 14 can be exposed, so that the grinding panel of the grinding disk 14 can be lifted, if the thickness of the grinding disk 14 When it is higher than the mounting ring 8, the gasket ring 17 cannot be added. The anti-fool groove 20 on the grinding disc 14 is aligned with the anti-fool column 18 and slid in until it cannot move. At this time, the mounting hole of the connecting flange 15 is aligned with the connecting hole 13 on the connecting ring 12. At this time, the connecting flange 15 and the connecting hole 13 are positioned by external screws, so that the installation of the grinding disc 14 can be completed, and the installation of the combined grinding wheel for cutting and grinding can be completed. Then, the output end of the external device is connected to the connecting ring 12, so that the entire connecting disc 1 can be driven to rotate eccentrically, and then the cutting ring 6 can be cut or the grinding disc 14 can be used for grinding. When the cutting ring 6 or the grinding disc 14 needs to be replaced, the above operation can be reversed to replace them separately, thereby saving resources and usage costs.
