The technical scheme of the utility model is further described below by the specific embodiments with reference to the accompanying drawings.

In order to solve the above problems, as shown in fig. 1 and 2, the present embodiment proposes a polishing wheel including a disk 1, an elastic ring 2, and a polishing ring 3, the disk 1 being capable of being mounted on a rotating shaft of a polishing apparatus. The side wall of the disc 1 is provided with a mounting groove 10 which is circumferentially arranged, and the mounting groove 10 is communicated with the inner cavity of the disc 1. The elastic ring 2 is compressively mounted to the inner cavity of the disc 1 such that the elastic ring 2 expands radially and abuts against the side wall of the disc 1. The polishing ring 3 is arranged in the mounting groove 10, the inner ring of the polishing ring 3 is sleeved on the outer ring of the elastic ring 2, and the lateral surface of the outer ring of the polishing ring 3 extends out of the lateral wall of the disc 1. When the disc 1 of the polishing wheel is arranged on the rotating shaft of the polishing device, the polishing device drives the polishing wheel to rotate through the rotating shaft so as to polish a product, so that the polishing device is integrated with a polishing function, the polishing device is not required to be purchased independently, and the production cost is reduced. Meanwhile, products are not required to be repeatedly disassembled and assembled between the grinding equipment and the polishing equipment, and polishing can be performed by replacing the polishing wheel on the grinding equipment, so that the production efficiency is improved.

The product is carrier glass, and the polishing wheel arranged on the grinding equipment can polish the edge part of the carrier glass so as to meet the requirements of the smoothness of the edge of the carrier glass. Of course, the product may be other workpieces requiring polishing, and is not particularly limited herein.

Specifically, the disc 1 is provided with a central hole in an axial penetrating manner, and the disc 1 is arranged on a rotating shaft of the grinding device through the central hole. It should be noted that, the original grinding wheel of the grinding device is provided with a mounting hole, and the grinding wheel is arranged on the rotating shaft through the mounting hole. The center hole of the disc 1 is the same as the mounting hole of the grinding wheel, so that the mounting size of the disc 1 and the grinding wheel is consistent, and the polishing wheel is convenient to be quickly mounted on the rotating shaft of the existing grinding equipment, thereby integrating the polishing function into the existing grinding equipment.

As shown in fig. 2, the elastic ring 2 is provided with openings 21 with adjustable intervals, so that the elastic ring 2 has an unclosed circular ring structure. When the elastic ring 2 is not compressed, the elastic ring 2 is in a natural placing state, and after the elastic ring 2 is compressed and installed in the inner cavity of the disc 1, the elastic ring 2 is always in a compressed state, so that the elastic ring 2 has a trend of radial expansion under the action of self elastic force, the outer ring side surface of the elastic ring 2 is always abutted against the inner side surface of the disc 1, the polishing ring 3 is always abutted against a part to be polished of a product, namely the elasticity of the elastic ring 2 can meet the feeding requirement of a polishing process, and the normal polishing operation of the polishing ring 3 is ensured.

Specifically, the spacing of the openings 21 of the elastic ring 2 is 5mm to 10mm. In the present embodiment, the pitch of the openings 21 may be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, or the like, and is not particularly limited herein. When the spacing of the openings 21 of the elastic ring 2 is too small, the range in which the elastic ring 2 is compressed is small, and the elastic force of itself is too small, so that it is difficult to satisfy the feeding requirement of the polishing process. When the spacing between the openings 21 of the elastic ring 2 is too large, the elastic force of the elastic ring 2 is too large, which results in inconvenient installation of the elastic ring 2 and easy damage to the rotating shaft of the grinding device. Further, the maximum elastic force of the elastic ring 2 in this embodiment is smaller than the limit value of the radial force that the rotating shaft can bear, so as to avoid the bending deformation of the rotating shaft under the influence of the elastic ring 2.

The polishing ring 3 of the present embodiment is made of a polishing material to polish the edges of the product to meet the finish requirements of the product. The polishing ring 3 can flexibly select polishing cloth wheels, nylon wheels, hemp wheels, wire wheels, miscellaneous cloth wheels and the like according to polishing requirements, and is not particularly limited herein.

Specifically, the inner ring side surface of the polishing ring 3 is adhered to the outer ring side surface of the elastic ring 2, so that stable installation of the polishing ring 3 and the elastic ring 2 is realized. In other embodiments, the polishing ring 3 may be fixedly mounted to the elastic ring 2 by screws or the like.

As shown in fig. 1 and 2, the disc 1 includes an upper tray 11 and a lower tray 12, the upper tray 11 is buckled on the lower tray 12, and a mounting groove 10 is enclosed between the upper tray 11 and the lower tray 12. The upper tray 11 and the lower tray 12 are buckled and assembled into the disc 1, and the disc 1 is arranged into a split type structure, so that the processing and the assembly are convenient.

Specifically, the upper tray 11 includes a cover plate 111 and an upper peripheral plate 112, and the upper peripheral plate 112 is provided around the peripheral edge of the cover plate 111. The lower tray 12 includes a bottom plate 121 and a lower peripheral plate 122, and the lower peripheral plate 122 is provided around the peripheral edge of the bottom plate 121. The elastic ring 2 abuts against the inner sides of the upper coaming 112 and the lower coaming 122, and the upper coaming 112 and the lower coaming 122 are arranged at intervals up and down and enclose the mounting groove 10. The upper coaming 112 and the lower coaming 122 together form the side wall of the disc 1 to provide a radial limit to the elastomeric ring 2 to prevent the elastomeric ring 2 from ejecting from the interior cavity of the disc 1.

Further, the cover plate 111 is provided with a first hole 110, the bottom plate 121 is provided with a second hole 120, and the first hole 110 and the second hole 120 are coaxial and jointly form a central hole of the disc 1. When the polishing wheel is installed in the polishing device, the rotating shaft of the polishing device sequentially penetrates through the first hole 110 and the second hole 120.

As shown in fig. 2, a guide sleeve 123 is provided on the inner bottom surface of one of the cover plate 111 and the bottom plate 121, and a through hole 113 coaxial with the guide sleeve 123 is provided on the other of the cover plate 111 and the bottom plate 121. The buffing wheel also includes a fastener 4 that passes through the through hole 113 and into the guide sleeve 123 to lock the upper tray 11 with the lower tray 12. The upper tray 11 and the lower tray 12 are assembled into an integral structure through the fastener 4, so that the structural strength and stability of the polishing wheel are improved.

In this embodiment, the bottom plate 121 is provided with a guide sleeve 123 on the inner bottom surface, and the cover plate 111 is provided with a through hole 113 coaxial with the guide sleeve 123. The fastener 4 is a bolt, and the inner hole of the guide sleeve 123 is a threaded hole. The bolt passes through the through hole 113 and then extends into the inner hole of the guide sleeve 123 to be in threaded connection with the guide sleeve 123. Specifically, four guide sleeves 123 are circumferentially arranged on the inner bottom surface of the bottom plate 121, four through holes 113 are formed in the cover plate 111 in a penetrating manner, and the four guide sleeves 123 and the four through holes 113 are coaxially arranged one by one. Four fasteners 4 are screwed with four guide sleeves 123, respectively. In other embodiments, the inner bottom surface of the cover plate 111 is provided with a guide sleeve 123, and the bottom plate 121 is provided with a through hole 113 coaxial with the guide sleeve 123. The number of the guide bush 123 and the through hole 113 may be one, two, three, or five or more, and is not particularly limited herein.

When the fastener 4 is tightened, the cover plate 111 abuts against the top surface of the guide sleeve 123. The height of the elastic ring 2 is lower than the axial height of the guide sleeve 123, so as to avoid the cover plate 111 and the bottom plate 121 clamping the elastic ring 2 to reduce the elastic force of the elastic ring 2, and avoid limiting the radial expansion trend of the elastic ring 2. Specifically, the height of the elastic ring 2 is about 1mm to 2mm lower than the axial height of the guide sleeve 123. In other embodiments, the difference between the height of the elastic ring 2 and the axial height of the guide sleeve 123 can be flexibly adjusted according to the actual working conditions, which is not limited herein.

The embodiment also provides a grinding device, and the grinding device includes pivot and foretell polishing wheel, and the disc 1 of polishing wheel is installed in the pivot of grinding device, and the grinding device passes through the pivot and drives the polishing wheel rotation to carry out polishing to the product, make the grinding device integrate and have the polishing function, need not to purchase polishing device alone, reduced manufacturing cost. Meanwhile, products are not required to be repeatedly disassembled and assembled between the grinding equipment and the polishing equipment, and polishing can be performed by replacing the polishing wheel on the grinding equipment, so that the production efficiency is improved.
