[0029] In the prior art, generally, a glass edge grinding device equipped with a flat grinding wheel is used for edge grinding operations. However, due to the fact that the flat grinding wheel can only perform flat grinding, only end face grinding or single-sided chamfering can be carried out separately in a single grinding. As a result, the overall size adjustment operation efficiency of special-shaped glass is low and cannot meet the high-efficiency operation requirements of the current industry.

[0030] To solve the above technical problems, the present utility model proposes a glass edge grinding wheel and a glass edge grinding device.

[0031] Please refer to Figures 1-5 , in an embodiment of the present utility model, the glass edge grinding wheel 100 is applied to a glass edge grinding device. Specifically, the glass edge grinding wheel 100 includes a wheel body 1. The axial center portion of the wheel body 1 is used to connect the drive shaft 210 of the rotation drive device 200. A recessed first edge grinding portion 2 is provided on the annular side portion of the wheel body 1. The first edge grinding portion 2 includes a first grinding surface 201, a second grinding surface 202, and a third grinding surface 203 that are connected in sequence. Among them, the second grinding surface 202 is used for grinding the side end face of the glass 400 to be processed, and the first grinding surface 201 and the third grinding surface 203 are used for chamfering the opposite side edges of the side of the glass 400 to be processed respectively.

[0032] The technical solution of the present utility model is that a first edge grinding part 2 is arranged in a sunken manner on the annular side of the wheel body 1. The first edge grinding part 2 includes a first grinding surface 201, a second grinding surface 202 and a third grinding surface 203 which are connected in sequence. During operation, first, the rotation driving device 200 is used to drive the wheel body 1 to perform a rotational movement. Subsequently, the first edge grinding part 2 of the wheel body 1 is brought into contact with the side edge of the glass 400 to be processed. During the contact between the two, the second grinding surface 202 grinds the side end surface of the glass 400 to be processed, and the first grinding surface 201 and the third grinding surface 203 respectively chamfer the opposite two side edges of the side edge of the glass 400 to be processed. Compared with the prior art where single grinding can only perform end surface grinding or single-sided chamfering respectively, the present utility model can simultaneously grind the end surface and the opposite two side edges of the side edge of the glass 400 to be processed at one time, thereby effectively improving the overall dimension adjustment operation efficiency of the special-shaped glass and meeting the high-efficiency operation requirements of the current industry.

[0033] Specifically, referring to the attached Figure 3 , a first included angle α is provided between the first grinding surface 201 and the second grinding surface 202, and the angle value range of the first included angle α is 30° to 60°; and / or, a second included angle β is provided between the third grinding surface 203 and the second grinding surface 202, and the angle value range of the second included angle β is 30° to 60°. With such a setting, the first included angle α and the second included angle β are the chamfering angles of the opposite two side edges of the side edge of the glass 400 to be processed. During actual operation, the operator can select a glass edge grinding wheel 100 with appropriate first included angle α and second included angle β according to the on-site situation for edge grinding operation.

[0034] Furthermore, the angles of the first included angle α and the second included angle β are equal, that is to say, the first grinding surface 201 and the third grinding surface 203 are symmetrically arranged on the opposite sides of the second grinding surface 202. With such a setting, it is ensured that the chamfers of the opposite two side edges of the side edge of the glass 400 to be processed are symmetrical. In this embodiment, the angles of both the first included angle α and the second included angle β are taken as 45°.

[0035] Specifically, a mounting hole 3 with a keyway 301 is provided at the axial center of the wheel body 1, and the driving shaft 210 of the rotation driving device 200 is connected to the wheel body 1 through the mounting hole 3. With such a setting, the driving shaft 210 of the rotation driving device 200 is connected to the mounting hole 3 with the keyway 301, and the keyway 301 is in interference fit with a key block (not shown in the attached drawing) on the driving shaft 210, thereby ensuring that the rotation driving device 200 can effectively drive the wheel body 1 to perform a rotational movement.

[0036] Furthermore, a recessed area 4 is provided in the axial center of the wheel body 1, and the mounting hole 3 is located at the inner bottom of the recessed area 4; the recessed area 4 is used to accommodate the mounting part 300 between the wheel body 1 and the drive shaft 210 of the rotary drive device 200. With such a setting, when the wheel body 1 and the drive shaft 210 of the rotary drive device 200 are fixedly connected to each other by mounting parts 300 such as nuts, in order to prevent the mounting part 300 from protruding outside the side surface of the wheel body 1 and affecting the overall aesthetics; therefore, a recessed area 4 for accommodating the mounting part 300 can be provided in the axial center of the wheel body 1.

[0037] As a preferred solution of the above embodiment, the second edge grinding part 5 is provided on the opposite sides or one side of the wheel body 1 along its axial direction. With such a setting, by providing the second edge grinding part 5, the side part of the wheel body 1 along its axial direction can also be fully utilized, so that it acts as a function of a surface grinding wheel to perform surface grinding on the side edge of the glass 400 to be processed. In this way, through the combination of the first edge grinding part 2 and the second edge grinding part 5, the operator can freely choose to use according to actual needs, which is beneficial to improving the applicability of the product. Among them, when the second edge grinding part 5 is provided on the opposite sides of the wheel body 1 along its axial direction, when the grinding function of one side of the second edge grinding part 5 decreases due to long-term grinding operation, the second edge grinding part 5 on the other side can be replaced to continue the grinding operation, so that both sides of the wheel body 1 along its axial direction can be effectively utilized, saving resources and being environmentally friendly. In this embodiment, the second edge grinding part 5 is only provided on one side of the wheel body 1 along its axial direction.

[0038] Specifically, the second edge grinding part 5 includes a fourth grinding surface 501 and a fifth grinding surface 502 with an annular structure, and the roughness of the fourth grinding surface 501 and the fifth grinding surface 502 is different; with such a setting, since the roughness of the fourth grinding surface 501 and the fifth grinding surface 502 is different, for example, the roughness of the fourth grinding surface 501 is greater than the roughness of the fifth grinding surface 502, so that the operator can perform rough grinding on the glass 400 to be processed with the fourth grinding surface 501 according to the actual situation, and perform fine grinding on the glass 400 to be processed with the fifth grinding surface 502, thereby increasing the functionality of the product.

[0039] Meanwhile, considering that the fourth grinding surface 501 and the fifth grinding surface 502 are arranged in a ring structure and sleeved with each other on the side of the wheel body 1 along its axial direction, in order to avoid the fourth grinding surface 501 and the fifth grinding surface 502 coming into contact with the glass to be processed 400 simultaneously when the wheel body 1 rotates, thereby causing interference between the fourth grinding surface 501 and the fifth grinding surface 502; in this embodiment, it is specified that the fourth grinding surface 501 is sleeved outside the fifth grinding surface 502, and the fifth grinding surface 502 protrudes outward from the fourth grinding surface 501; in this way, by placing the fourth grinding surface 501 and the fifth grinding surface 502 on different planes respectively, it is convenient for the operator to select a suitable grinding surface (the fourth grinding surface 501 or the fifth grinding surface 502) for grinding operations according to the actual situation. It can be understood that when the operator needs to perform rough grinding, the side of the glass to be processed 400 is brought into contact with the fourth grinding surface 501 located outside the side of the wheel body 1; when the operator needs to perform fine grinding, the side of the glass to be processed 400 is brought into contact with the fifth grinding surface 502 located inside the side of the wheel body 1; it should be noted to avoid the glass to be processed 400 moving back and forth on the fourth grinding surface 501 and the fifth grinding surface 502 simultaneously during the grinding operation.

[0040] Further, referring to the attached Figure 3 , a connecting inclined surface 503 is provided at the junction of the fourth grinding surface 501 and the fifth grinding surface 502. A third included angle γ is provided between the connecting inclined surface 503 and the fourth grinding surface 501, and the angular range of the third included angle γ is 30 to 75 degrees. With such a setting, since the fourth grinding surface 501 and the fifth grinding surface 502 are respectively arranged on different planes, in order to avoid the glass to be processed 400 being damaged when the operator makes a mistake during the grinding process and the glass to be processed 400 contacts the junction of the fourth grinding surface 501 and the fifth grinding surface 502; in this embodiment, a connecting inclined surface 503 is provided at the junction of the fourth grinding surface 501 and the fifth grinding surface 502 as a transition surface, and it is specified that the angular range of the third included angle γ between the connecting inclined surface 503 and the fourth grinding surface 501 is 30 to 75 degrees, so that the glass to be processed 400 can smoothly transition between the fourth grinding surface 501 and the fifth grinding surface 502 along the connecting inclined surface 503, ensuring that the operator has enough time to readjust the position of the glass to be processed 400. In this embodiment, the angular value of the third included angle γ is 60 degrees.

[0041] Further, referring to the attached Figure 3, the horizontal distance difference d between the fourth grinding surface 501 and the fifth grinding surface 502 is 3 to 5 mm. With such a setting, since the fourth grinding surface 501 and the fifth grinding surface 502 are respectively arranged on different planes, in order to prevent the glass to be processed 400 from being damaged when the operator makes a mistake during the grinding process and causes the glass to be processed 400 to contact the junction of the fourth grinding surface 501 and the fifth grinding surface 502; in this embodiment, the horizontal distance difference d between the fourth grinding surface 501 and the fifth grinding surface 502 is limited within a small value range to avoid too large a horizontal drop between the fourth grinding surface 501 and the fifth grinding surface 502.

[0042] This embodiment also discloses a glass edge grinding device, including a rotation driving device and the glass edge grinding wheel of any one of the above embodiments, and the driving shaft of the rotation driving device is connected to the central part of the glass edge grinding wheel. For the specific structure of the glass edge grinding wheel, reference can be made to the above embodiments. Since this glass edge grinding wheel adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, and will not be elaborated here one by one.

[0043] It should be noted that other contents of the glass edge grinding wheel and the glass edge grinding device disclosed in the present invention are prior art and will not be elaborated here.

[0044] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All those that are directly / indirectly applied in other related technical fields of the present invention are included in the patent protection scope of the present invention.
