Description

Technical Field

[0001] The invention relates to a glass grinding wheel based on standard module design and a processing method thereof. Background Art

[0002] Glass grinding wheel is a commonly used glass processing tool with the advantages of high grinding efficiency and high processing precision. The production of glass grinding wheel requires the selection of high-quality abrasives and adhesives, and careful grinding and production. The basic forms of existing glass grinding wheels are three-slot, five-slot or multi-slot, among which the basic is a flying disc form, with an axial hole in the middle and a mounting reference surface on the bottom (for correction). The size from the mounting surface to the grinding working surface needs to be manually corrected to ensure the normal grooving work.

[0003] However, when the grinding wheel blank is produced, the reference surface of the inner ring-mounted protrusion is lower than the outer protrusion plane in order to prevent the reference surface from being worn when placed and the peripheral groove is formed. Therefore, during processing, the reference surface cannot be directly used as the reference of the processing device, and measurement and calculation are required to obtain the required position distance data. Since the data measured on the grinding wheel are very small, the accuracy requirement is very high, even reaching the accuracy requirement of 0.001, which will make the actual error very large. In the existing installation method, manual correction is used to eliminate the influence of the error to meet the use requirements. The correction process is power-on correction, which often wastes one or two pieces of glass raw materials and takes about 0.5 hours. This is time-consuming and labor-intensive. Therefore, a processing method is needed to accurately measure the value of the reference surface to the edge of the groove. Summary of the invention

[0004] The purpose of the present invention is to solve the above deficiencies in the prior art and to provide a glass grinding wheel based on a standard module design and a processing method thereof.

[0005] A method for processing a glass grinding wheel based on a standard module design comprises the following steps:

[0006] S1: Fix the fixture at the processing position of the processing device;

[0007] S2: Fix the blank on the fixture so that its reference surface fits with the installation surface of the fixture;

If not, adjust the fixture to make the correction plane completely fit with the reference surface on the other side;

[0009] S4: Remove the rough material and calibrate the processing device to zero based on the mounting surface of the fixture;

[0010] S5: Fix the blank on the fixture and start the processing device to process it.

[0011] Furthermore, the blank is a disc-shaped structure with a through hole at the center of its bottom surface, and an annular raised reference surface is provided on the periphery of the hole opening on both sides of the through hole. An annular raised plane is provided on the edge of the bottom surface on both sides of the blank, and the raised height of the raised plane is higher than the raised height of the reference surface.

[0012] Furthermore, the fixture includes a base and an upper cover, a cylindrical fixing platform is provided at the center of the upper end surface of the base, a limiting column is provided at the center of the upper end surface of the fixing platform, and a slot is provided on the upper end surface of the limiting column;

The lower end surface of the upper cover is connected to the reference surface on the other side of the blank, and the upper end surface of the upper cover is parallel to the reference surface of the blank.

[0014] Furthermore, the lower end surface of the upper cover is provided with an annular protrusion, and the annular protrusion is used to be inserted into the annular groove on the periphery of the reference surface of the blank.

[0019] Beneficial effect: Compared with the prior art, the present invention adds a clamp so that the mounting surface on it fits with the reference surface of the blank material, thereby realizing the zeroing work of the processing device based on the reference surface of the blank material, eliminating the need for calculation to obtain the position data of the starting point of processing. Now, the distance can be set directly according to the requirements through the clamp, so that the position of the pits and grooves on the periphery of the processed grinding wheel is more accurate, meeting the position accuracy requirements of the subsequent use of the grinding wheel, eliminating the steps required for adjustment when using the grinding wheel, improving work efficiency and reducing costs.

[0031] S1: Fix the fixture at the processing position of the processing device;

[0032] S2: Fix the blank on the fixture so that its reference surface 8 fits with the mounting surface of the fixture;

[0033] S3: Make the reference surface 8 on the other side of the blank 2 contact with the correction plane, rotate the fixture, and observe whether the reference surface 8 on the other side is completely fitted with the correction plane.

Annular protrusion planes 9 are provided on the edges of the bottom surfaces on both sides of the blank 2. The protrusion height of the protrusion plane 9 is higher than the protrusion height of the reference surface 8.

[0037] In this embodiment, the clamp includes a base 1 and an upper cover 3. A cylindrical fixing platform 4 is provided at the center of the upper end surface of the base 1. A limiting column 5 is provided at the center of the upper end surface of the fixing platform 4. A slot is provided on the upper end surface of the limiting column 5.

[0039] In this embodiment, the lower end surface of the upper cover 3 is provided with an annular protrusion 7 , and the annular protrusion 7 is used to be inserted into the annular groove on the periphery of the reference surface 8 of the blank 2 .

[0040] In this embodiment, the base 1 is a rib-shaped three-dimensional structure.

[0041] In this embodiment, a cushion is provided at the contact position between the lower end surface of the upper cover 3 and the reference surface 8 of the blank 2 .
