Description

Technical Field

[0001] The utility model relates to the field of grinding wheels, in particular to a special-shaped grinding wheel. Background Art

[0002] Grinding wheel is also called bonded abrasive. Grinding wheel is a bonded abrasive that is made by bonding ordinary abrasive into a certain shape, most of which are circular, with a through hole in the center and a certain strength. It is generally composed of abrasive, bonding agent and pores. These three parts are often called the three elements of bonded abrasive. According to the different classifications of bonding agents, common ones are ceramic grinding wheel, resin grinding wheel and rubber grinding wheel. Grinding wheel is the most widely used and the most widely used abrasive tool. It rotates at high speed when used, and can perform rough grinding, semi-fine grinding and fine grinding, as well as grooving and cutting on the outer circle, inner circle, plane and various profiles of metal or non-metal workpieces. Special-shaped grinding wheel is also one of the many grinding wheels. Special-shaped grinding wheel is a grinding wheel specially designed for complex shapes or special needs. It has high flexibility and adaptability. Special-shaped grinding wheel is mainly composed of grinding wheel matrix and adhesive. Grinding wheel matrix is ​​the main part of grinding wheel. It can be any shape such as round, oval, triangle, etc.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model provides Figure 1-5 The special-shaped grinding wheel shown in the figure comprises a main wheel disc base 1, a special-shaped wheel disc 2 is fixedly connected to one side of the main wheel disc base 1, an inner connecting hole 3 is opened inside the main wheel disc base 1, a fixing bolt 4 is passed through the inner connecting hole 3, an outer wheel disc sleeve 5 is movably connected to one end of the fixing bolt 4, a cutting-in type wheel body 6 is fixedly installed on one side of the outer wheel disc sleeve 5, a cutting-in groove 7 is opened inside the cutting-in type wheel body 6, a shaft sleeve docking groove 8 is opened inside the special-shaped wheel disc 2, a fixing groove 9 is opened inside the shaft sleeve docking groove 8, a fixing block 10 is movably connected inside the fixing groove 9, and a shaft sleeve disc 11 is fixedly installed on one end of the fixing block 10. When the special-shaped grinding wheel is used to grind products with different requirements, the main wheel disc base 1 can be directly used to complete the grinding of the product for conventional internal and external grinding, and the cutting-in type grinding can be performed by installing the fixing bolt 4 in the inner connecting hole 3 on the outside of the main wheel disc base 1 through the fixing bolt 4 in the inner connecting hole 3.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the outer wheel disc sleeve 5 is threadedly connected to the main wheel disc base 1, and the fixing bolts 4 are evenly spaced on the main wheel disc base 1. The fixing bolts 4 are convenient for operators to quickly disassemble or install the outer wheel disc sleeve 5 according to different processing requirements. The fixing block 10 fixedly installed on one side of the shaft sleeve disc 11 is engaged with the fixing slot 9 opened inside the shaft sleeve docking groove 8. The external size of the fixing block 10 is consistent with the internal size of the fixing slot 9. The shaft sleeve disc 11 of appropriate size can be selected according to the size of the external shaft, and can be quickly installed through the fixing slot 9 and the fixing block 10.

[0027] like Figure 1 , Figure 4 and Figure 5As shown, a positioning bolt 12 passes through the outside of the sleeve disc 11, and a connecting sleeve 13 is fixedly installed on one side of the sleeve disc 11. The positioning bolt 12 further enhances the stability of the sleeve disc 11 when connected to the special-shaped wheel disc 2. A reinforcing connecting block 14 is fixedly installed inside the connecting sleeve 13, and an inner shaft annular piece 15 is fixedly connected to one side of the reinforcing connecting block 14. The outer side of the inner shaft annular piece 15 is provided with anti-skid vertical grooves 16. The inner shaft annular piece 15 and the anti-skid vertical grooves 16 enhance the friction force after the special-shaped grinding wheel and the external shaft are connected. The number of the inner shaft annular pieces 15 is set to four, and the four inner shaft annular pieces 15 are distributed in a circular array on the connecting sleeve 13. The four groups of inner shaft annular pieces 15 make the connection and installation of the external shaft and the special-shaped grinding wheel more stable, and also increase the torque of the external shaft when driving the special-shaped grinding wheel to rotate.

[0028] The practical working principle of the present invention is as follows: firstly, the external power supply is turned on. When the special-shaped grinding wheel and the external shaft of the external machine are to be installed, the shaft sleeve 11 of appropriate size can be selected according to the size of the external shaft, and the special-shaped wheel disc 2 can be installed through the fixing slot 9 and the fixing block 10. Then, the stability of the connection between the shaft sleeve 11 and the special-shaped wheel disc 2 is further enhanced through the positioning bolt 12. Then, when the external shaft passes through the inside of the special-shaped grinding wheel, the inner shaft annular piece 15 and the anti-skid vertical grain 16 enhance the friction force after the connection between the special-shaped grinding wheel and the external shaft, making the connection and installation of the external shaft and the special-shaped grinding wheel more stable. At the same time, it also increases the torque of the external shaft when driving the special-shaped grinding wheel to rotate. In this way, the external machine can be started after the installation of the special-shaped grinding wheel is completed, and the special-shaped grinding wheel is driven by the rotation of the external shaft to grind different products. During grinding, for conventional internal and external grinding, the main wheel disc base 1 can be used directly to complete the grinding work on the product. Then, if it is a cut-in grinding process, the cut-in wheel body 6 can be installed on the outside of the main wheel disc base 1 through the fixing bolts 4 in the internal connecting hole 3, and the cut-in processing of the product can be completed through the cut-in groove 7. In this way, the grinding wheel structure not only meets the requirements of special-shaped grinding wheels, but also meets the internal and external and cut-in grinding requirements of products with different requirements. It also reduces the frequency of disassembly and assembly of special-shaped grinding wheels when facing products with different grinding requirements, and improves the overall scope and applicability of the grinding wheel. Finally, after completing the installation and use of all special-shaped grinding wheels according to the above operations, the special-shaped grinding wheel is maintained daily, and the external power supply is cut off if it is not used for a long time. In this way, the use process of the special-shaped grinding wheel is completed.

[0029] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
