Description

Technical Field

[0001] The utility model relates to the technical field of edge grinding wheels, in particular to a grinding wheel used for edge grinding of optical glass original sheets. Background Art

[0002] During the processing of optical glass, it is necessary to first cut the optical glass into the required shape, and then grind the edge of the optical glass with the grinding wheel on the edge grinding machine, which can not only grind off the sharp edges caused by cutting the optical glass, but also ensure the flatness, smoothness and light transmittance of the optical glass. The edge grinding machine contacts the optical glass disc through the edge grinding wheel to perform the edge grinding operation.

[0003] Grinding wheel in the prior art Figure 1 As shown, a diamond layer is often electroplated on the side of a disc-shaped steel material, and the diamond layer is used to grind the optical glass. However, during long-term use of the grinding wheel, the diamond layer on its surface will be worn out, and the worn grinding wheel will affect the grinding accuracy of the optical glass and reduce the quality of the finished optical glass. Therefore, the grinding wheel in the prior art is often replaced during use.

[0004] During the processing of optical glass, a 45-degree chamfer needs to be set to prevent the optical glass from being broken during subsequent processing such as coating, gluing, assembly, etc. In the prior art, two processes are usually used for processing, which takes a long time and causes large grinding wheel loss. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art grinding wheel, such as poor durability, short service life, and inability to set a 45-degree chamfer, the inventor improved the shape and structure of the grinding wheel during the long-term production process in the factory and proposed a grinding wheel for edge grinding of optical glass original sheets of the utility model, and the detailed technical scheme is as follows:

[0006] A grinding wheel for edge grinding of optical glass original sheets comprises a grinding wheel body and a connecting plate embedded in the grinding wheel body; the grinding wheel body comprises a ring-shaped grinding portion, a ring-shaped connecting portion located on both sides of the grinding portion and protruding outward relative to the grinding portion, and a chamfering portion located between the grinding portion and the connecting portion and inclined at a 45-degree angle to the surface of the grinding portion.

[0007] Furthermore, the grinding part and the chamfering part are both composed of diamond abrasive, a binder and a filler.

[0008] Furthermore, the connection disk is a circular cylindrical structure, including a through hole that is concentrically arranged with the connection disk and penetrates the connection disk, and bolt holes that are evenly distributed on the upper surface of the connection disk.

[0009] Furthermore, there are two connecting plates, which are bonded together by glue and connected by bolts; and the two connecting plates are bonded to the inner surface of the grinding wheel body by glue on the outer sides.

[0010] Furthermore, a planar mounting surface is provided on the inner side of the grinding portion; through holes and bolt holes are correspondingly provided on the mounting surface; the connecting plate is bonded to the mounting surface by glue, and is connected to the mounting surface by bolts.

[0011] Furthermore, a positioning block protruding from the mounting surface is arranged on the mounting surface; and a positioning groove matching the positioning block is arranged on the corresponding surface of the connecting plate.

[0012] The beneficial effects of the utility model are as follows: by arranging the grinding part and the chamfering part on the grinding wheel body, chamfering and grinding can be performed simultaneously during one edge grinding process, thus saving the process flow, reducing the production time of optical glass, and improving production efficiency; at the same time, the grinding part and the chamfering part are made of diamond abrasive, and their service life is longer than that of ordinary grinding wheels. In the utility model, by arranging the grinding part in the middle and the chamfering parts on both sides, both sides of the grinding wheel can be used for edge grinding and chamfering of optical glass. If the processing is carried out by changing the side every other day, the service life of the structure can be greatly increased. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In order to increase the durability of the grinding wheel and the convenience of the processing technology, the utility model proposes a grinding wheel for edge grinding of optical glass original sheets, and its external structure is as follows Figure 2 As shown, it is a disc-shaped structure, with the middle part being concave inwards and the upper and lower sides being convex outwards. It mainly comprises a grinding wheel body 100 and a connecting disc 200 embedded in the grinding wheel body 100.

[0026] The first embodiment of the grinding wheel structure is as follows Figure 3 As shown in FIG. 1 , the grinding wheel body 100 includes a grinding wheel body 100 having a hollow center and connecting plates 200 located at the upper and lower sides and embedded in the grinding wheel body 100. The structure of the grinding wheel body 100 is shown in FIG. Figure 4 As shown, it includes a ring-shaped grinding part 110, a ring-shaped connecting part 120 located on both sides of the grinding part 110 and protruding outward relative to the grinding part 110, and a chamfering part 130 located between the grinding part 110 and the connecting part 120 and inclined at 45 degrees to the surface of the grinding part 110. The grinding part 110 and the chamfering part 130 are composed of diamond abrasives, a binder and a filler. The grinding part 110 is used to grind the edges of optical glass, and the chamfering part 130 is used to process a 45-degree chamfer on the optical glass in the same process. Since the grinding part 110 and the chamfering part 130 are not made by electroplating a diamond layer, but by using diamond abrasives, they have a long service life. At the same time, both sides of the grinding wheel can be used for edge grinding and chamfering. The method of grinding the left and right sides every other day can further increase the service life of the structure. By adding a chamfering layer with a 45-degree inclined plane on the outside of the grinding part 110, the chamfering can be processed while the edge grinding is being performed, which saves the process flow, reduces the production time of the optical glass, and improves the production efficiency.

[0027] Connection plate 200 Figure 5As shown, it is a circular cylindrical structure, including a through hole 210 that is concentrically arranged and penetrates the connecting plate 200, and a bolt hole 220 located on the upper surface of the connecting plate 200. The two connecting plates 200 are bonded by glue and the bolt holes 220 of the two connecting plates 200 are connected by bolts. The connecting plate 200 is mainly used to connect with the main shaft of the edge grinding machine, and the main shaft passes through the through hole 210 and drives the grinding wheel body 100 to rotate.

[0028] The second embodiment of the grinding wheel structure is as follows Figure 6 As shown, in the first embodiment, the connecting plate 200 and the grinding wheel body 100 are bonded by glue on the side, and the connection surface is small, which is easy to fail during long-term use and cause the grinding wheel to be scrapped. In the second embodiment, a mounting surface 140 is provided inside the grinding part 110 of the grinding wheel body 100, and the mounting surface 140 is a plane on the inner side of the grinding part 110, on which corresponding through holes and bolt holes are provided. When the connecting plates 200 on both sides are connected, the mounting surfaces 140 are first bonded by glue, and then the connecting plates 200 and the grinding wheel body 100 are connected by bolts. Under this connection mode, not only the effective connection area of ​​the glue is increased, but also the bolt connection is increased, which greatly enhances the stability of the structure.

[0029] The third embodiment of the grinding wheel structure is as follows Figure 7 As shown, although the second embodiment greatly increases the connection strength between the connecting plate 200 and the grinding wheel body 100, it is found in actual production that the alignment between the bolt holes is difficult. This is because the position of the bolt holes in the grinding wheel body is fixed, and the connecting plates 200 on both sides need to be rotated to a specific position to achieve the connection of the bolts. Therefore, the third embodiment is provided with a positioning block 150 protruding from the mounting surface 140 on the mounting surface 140, and a matching positioning groove 230 is provided on the corresponding surface of the connecting plate 200. The connecting plate 200 and the grinding wheel body 100 can be quickly positioned by the concave-convex positioning method to achieve a quick connection of the structure. The shape of the positioning block 150 and the positioning groove 230 can be, but not limited to, common shapes such as a rectangular column and a cylinder.

[0030] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
