Problems solved by technology

After the grinding wheel is assembled on the main shaft, if there is a large gap between the center hole of the grinding wheel and the main shaft, the coaxial error between the grinding wheel and the main shaft will be too large, resulting in the radial runout error of the outer surface of the grinding wheel when the grinding wheel rotates. Too big
During the use of the grinding wheel, the disassembly and assembly of the grinding wheel on the main shaft will cause a certain degree of wear on the main shaft, making the main shaft smaller
In addition, when the roundness error and size error of the spindle are large, the gap between the spindle and the center hole of the grinding wheel will also increase.
If the glass edging machine is in such a situation, the diamond grinding wheel on it will hit the glass if the radial runout is too large during use, causing the glass to collapse and become a waste product
In addition, high-quality grinding wheels have the characteristics of high wear resistance and high efficiency. If they are installed on a worn spindle, the eccentricity will be difficult to run in, and the edge of the glass will be more serious. High-quality grinding wheels cannot be used, and their high efficiency must be If it is not fully utilized, only low-quality grinding wheels can be used, which not only seriously affects the production efficiency and processing quality of the glass processing industry, but also affects the improvement of the technical level and economic benefits of grinding wheel manufacturing enterprises

example 1

[0021] The diameter of the grinding wheel is 600mm, the thickness of the grinding wheel is 200mm, the diameter of the central hole is 32mm, and the number of annular grooves is 1. The annular groove is located at one end of the central hole, and there is no upper groove wall. The section of the groove is L-shaped, and the lower edge of the groove is chamfered, such as image 3 as shown in a. The depth of the groove is 200 mm, and the width of the groove is 100 mm. The outer diameter of the elastic ring matches the annular groove, the outer diameter is 432mm, the thickness is 98mm, the inner diameter is 22mm smaller than the central hole diameter by 10mm, and its cross section is rectangular with chamfering, such as image 3 as shown in b; or the section of the elastic ring is L-shaped, and its outer ring surface is a convex surface, such as image 3 as shown in c.

example 2

[0023] The diameter of the grinding wheel is 150mm, the thickness of the grinding wheel is 20mm, the diameter of the center hole is 22mm, the number of annular grooves is 2, and the cross section of the groove is V-shaped, such as Figure 4 as shown in a. The depth of the groove is 50 mm, and the width of the groove is 5 mm. The outer diameter of the elastic ring is 122mm, the thickness is 5mm, the inner diameter is 17mm smaller than the diameter of the central hole 5mm, and its cross-section is 0-shaped, such as Figure 4 as shown in b; or the section of the elastic ring is V-shaped, and its outer ring surface is a convex surface, such as Figure 4 as shown in c.

example 3

[0025] The diameter of the grinding wheel is 450mm, the thickness of the grinding wheel is 150mm, the diameter of the center hole is 22mm, the number of annular grooves is 12, and the cross section of the groove is 匚-shaped, such as Figure 5 as shown in a. The depth of the groove was 100 mm, and the width of the groove was 8 mm. The outer diameter of the elastic ring is 222mm, the thickness is 7.5mm, and its inner diameter is 14mm smaller than the central hole diameter of 8mm. The cross-sectional shape of the elastic ring is U-shaped. Figure 5 as shown in b; or the section of the elastic ring is rectangular, and its upper and lower surfaces and inner and outer ring surfaces are zigzag, such as Figure 5 as shown in c.

Abstract

A self-regulating abrasive wheel for automatically regulating the axiality between the abrasive wheel and its central axle features that there are 1-20 ring slots on the inner surface of the central hole of said abrasive wheel and the elastic rings are embedded in said ring slots for interference fit between central axle and elastic ring, so preventing radial jump of abrasive wheel.

Description

(1) Technical field [0001] The invention relates to a grinding wheel for grinding, in particular to a self-aligning grinding wheel. (2) Technical background [0002] Grinding wheels are used in the processing of brittle and hard materials such as glass, stone, and ceramics. The grinding wheel is installed on the motor drive shaft (i.e. the main shaft), and the main shaft drives the grinding wheel to rotate for grinding operations. After the grinding wheel is assembled on the main shaft, if there is a large gap between the center hole of the grinding wheel and the main shaft, the coaxial error between the grinding wheel and the main shaft will be too large, resulting in the radial runout error of the outer surface of the grinding wheel when the grinding wheel rotates. too big. During the use of the grinding wheel, the multiple disassembly and assembly of the grinding wheel on the main shaft will cause a certain degree of wear on the main shaft, making the main shaft smaller...
