Description

Technical Field

[0001] The utility model is a single-reference processing jig for a glass grinding wheel. Background Art

[0002] Glass grinding wheels are a commonly used tool for glass processing, offering advantages such as high grinding efficiency and precision. They require the use of high-quality abrasives and adhesives, meticulously ground, and crafted. Existing glass grinding wheels typically come in three-, five-, or multi-grooved configurations. These typically resemble a flying disc, with a central axial hole and a mounting datum surface (for calibration) on the bottom. Manual calibration is required to ensure proper grooving.

[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 in the peripheral groove. Therefore, during processing, the reference surface cannot be directly used as the reference of the processing device. 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.

[0004] In the existing installation method, manual correction is used to eliminate the influence of errors 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, which is time-consuming and labor-intensive. Utility Model Content

[0005] The purpose of the utility model is to solve the above deficiencies in the prior art and to provide a single-reference processing fixture for glass grinding wheels.

[0006] A single-reference processing fixture for glass grinding wheels, comprising a base and an upper cover, wherein 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;

[0007] A positioning column is provided at the center of the lower end surface of the upper cover, and the positioning column is inserted into the slot. 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;

[0008] The blank is a disc-shaped structure with a through hole at the center of its bottom surface. There are annular raised reference surfaces on the periphery of the hole on both sides of the through hole. There are annular raised planes on the edges of the bottom surface on both sides of the blank. The raised height of the raised plane is higher than the raised height of the reference surface.

[0009] 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.

[0010] Furthermore, the base is a ribbed three-dimensional structure.

[0011] Furthermore, a cushion is provided at the contact position between the lower end surface of the upper cover and the reference surface of the blank.

[0012] Furthermore, the inner side wall of the slot is provided with at least one annular first groove, the outer side wall of the positioning column is provided with at least one annular second groove corresponding to the first groove, and an elastic O-ring is provided in the second groove.

[0013] Furthermore, a groove is provided on the outer side wall of the annular protrusion on the lower end surface of the upper cover, and an elastic O-ring is provided in the groove.

[0014] Beneficial effects: Compared with the prior art, the present invention adds a jig so that the mounting surface thereof fits with the reference surface of the blank, thereby realizing the zero calibration of the processing device based on the reference surface of the blank, 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 fixture, so that the position of the 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 need for adjustment steps when using the grinding wheel, improving work efficiency and reducing costs.

[0021] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0022] like Figure 1-5 As shown, the base 1, the blank 2, the upper cover 3, the fixing platform 4, the limiting column 5, the positioning column 6, the annular protrusion 7, the reference surface 8, and the protruding plane 9;

[0023] A single-reference processing fixture for glass grinding wheels, comprising 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.

[0024] A positioning post 6 is provided at the center of the lower end surface of the upper cover 3. The positioning post 6 is inserted into the slot. The lower end surface of the upper cover 3 is connected to the reference surface 8 on the other side of the blank 2. The upper end surface of the upper cover 3 is parallel to the reference surface 8 of the blank 2.

[0025] The blank 2 is a disc-shaped structure with a through hole at the center of its bottom surface. A reference surface 8 with an annular protrusion 7 is provided on the periphery of the hole on both sides of the through hole. An annular raised plane 9 is provided on the edge of the bottom surface on both sides of the blank 2. The raised height of the raised plane 9 is higher than the raised height of the reference surface 8.

[0026] In this example, 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.

[0027] In this example, the base 1 is a ribbed three-dimensional structure. Specifically, the fixture is fixed by a supporting mechanism on the processing device, and the prismatic structure is more convenient to fix.

[0028] 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 to reduce wear.

[0029] In this example, the inner wall of the slot is provided with at least one annular first groove, and the outer wall of the positioning column 6 is provided with at least one annular second groove corresponding to the first groove. An elastic O-ring is provided in the second groove, and part of the O-ring is stuck in the first groove and part is stuck in the second groove to ensure that the upper cover 3 will not fall off during processing.

[0030] In this example, a groove is provided on the outer side wall of the annular protrusion on the lower end face of the upper cover, and an elastic O-ring is provided in the groove, which can ensure the tightness of the assembly between the annular protrusion of the upper cover and the blank and ensure that the two will not shake.

[0031] It should be noted that when the grinding wheel blank 2 is manufactured, the inner annular raised reference surface 8 is lower than the outer raised plane 9 in order to prevent the reference surface 8 from being worn when placed in the peripheral groove. Therefore, during processing, the reference surface 8 cannot be directly used as the reference of the processing device, and measurement and calculation are required to obtain the required position distance data. The present invention uses a fixture to enable the processing device to be directly zeroed using the reference surface 8 as the reference, so as to start processing. This can reduce errors and determine the vertical distance from the reference surface 8 to the edge of the groove 10, where the vertical distance is Figure 5 The d in.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
