[0002] When a grinding wheel is used to grind a large surface of a glass cover plate, a large amount of heat will be generated, which not only affects the service life of the grinding wheel, but also affects the yield of the glass cover plate. Therefore, it is necessary to adopt an effective cooling method. In the prior art, a coolant is sprayed to the side of the grinding wheel, and a slot or a cross slot is opened on the bottom of the grinding wheel. This cooling method has the problem that the coolant cannot fully enter the inside of the grinding wheel, resulting in the problem that the grinding wheel cannot be effectively cooled, resulting in a reduction in the service life of the grinding wheel and the processing yield of the glass cover plate. Summary of the invention

[0003] In order to solve the technical problems existing in the background technology, the present invention provides a grinding wheel for processing a glass cover plate.

[0004] The grinding wheel for processing a glass cover plate comprises: a grinding wheel body, the bottom surface of the grinding wheel body is a working area for grinding the glass cover plate, a plurality of evenly spaced first guide grooves are opened on the side wall of the grinding wheel body along the axial direction of the grinding wheel body, a plurality of evenly spaced second guide grooves are opened on the bottom surface of the grinding wheel body along its radial direction, one end of the second guide groove is located on the outer peripheral surface of the grinding wheel body, and the other end is close to the center of the grinding wheel body, and the first guide groove and the second guide groove are connected on the bottom outer peripheral surface of the grinding wheel body.

[0006] Preferably, the second guide groove is a crescent-shaped arc-shaped groove, and the bending direction of the arc-shaped groove is consistent with the machining rotation direction of the grinding wheel body.

[0007] Preferably, the second guide hole includes a second upper guide hole and a second lower guide hole, the second upper guide hole is a funnel-shaped hole that is larger at the top and smaller at the bottom, the top diameter of the funnel-shaped hole is equal to that of the first guide hole, the aperture of the second lower guide hole is equal to the bottom diameter of the funnel-shaped hole, and the bottom of the second lower guide hole is circumferentially connected to one end of the second guide groove close to the center of the grinding wheel body.

[0008] Preferably, a plurality of third flow guide holes penetrating the first flow guide holes and the second flow guide grooves are formed on the grinding wheel body.

[0009] Preferably, the flow inlet is detachably connected to the grinding wheel body.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

The first guide hole and the second guide hole can store the coolant. At the same time, because the flow direction of the coolant on the bottom surface of the grinding wheel body is from the center of the grinding wheel body to the periphery of the grinding wheel body, and the glass fragments are also discharged from the center of the grinding wheel body to the periphery of the grinding wheel body, the coolant and the glass fragments can flow and be discharged more powerfully under the action of centrifugal force, thereby ensuring the cooling effect of the grinding wheel and the glass cover plate and the processing effect of the glass cover plate. In addition, not opening the first guide groove on the grinding wheel body also ensures the structural strength of the grinding wheel body. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The specific implementation of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] Reference Figure 1, which is the first embodiment of the present invention, a grinding wheel for processing a glass cover plate, comprises: a grinding wheel body 1, the bottom surface of the grinding wheel body 1 is a working area for grinding the glass cover plate, and is characterized in that a plurality of evenly spaced first guide grooves 11 are opened on the side wall of the grinding wheel body 1 along the axial direction of the grinding wheel body 1, and a plurality of evenly spaced second guide grooves 12 are opened on the bottom surface of the grinding wheel body 1 along its radial direction, one end of the second guide groove 12 is located on the outer peripheral surface of the grinding wheel body 1, and the other end is close to the center of the grinding wheel body 1, and the first guide groove 11 and the second guide groove 12 are connected on the bottom outer peripheral surface of the grinding wheel body 1.

[0020] The grinding wheel will be connected to the machine tool shaft through the tool handle 3 to grind the glass cover plate. The first guide groove 11 will guide the coolant sprayed on the side wall of the grinding wheel body 1 into the second guide groove 12, so as to fully cool the bottom working area of ​​the grinding wheel body 1. The second guide groove 12 can also discharge the ground glass debris from the bottom working area of ​​the grinding wheel body 1 in time, thereby improving the service life of the grinding wheel and the processing yield of the glass cover plate.

[0021] Reference Figure 2 , Figure 4 , which is the second embodiment of the present invention, the grinding wheel also includes an inlet portion 2, which is located on the top wall of the grinding wheel body 1 and is coaxially arranged with the grinding wheel body 1, the diameter of the inlet portion 2 is smaller than the diameter of the grinding wheel body 1, the first guide groove 11 is located on the side wall of the inlet portion 2, and a first guide hole 21 is opened in the center of the inlet portion 2 along its axial direction and penetrates the bottom surface of the inlet portion 2, the first guide hole 21 is connected with the first guide groove 11 in the circumferential direction, and a second guide hole 13 is opened on the grinding wheel body 1 along its axial direction and penetrates the grinding wheel body 1, the top of the second guide hole 13 is connected with the bottom of the first guide hole 21, and the bottom of the second guide hole 13 is connected with one end of each second guide groove 12 close to the center of the grinding wheel body 1 in the circumferential direction.

[0022] The coolant will enter the first guide hole 21 through the first guide groove 11, then enter the second guide hole 13, and then flow into the second guide groove 12, so as to cool the working area on the bottom surface of the grinding wheel body 1. The first guide hole 21 and the second guide hole 13 can store the coolant. At the same time, because the flow direction of the coolant on the bottom surface of the grinding wheel body 1 is from the center of the grinding wheel body 1 to the periphery of the grinding wheel body 1, and the glass fragments are also discharged from the center of the grinding wheel body 1 to the periphery of the grinding wheel body 1, the coolant and the glass fragments can flow and be discharged more powerfully under the action of centrifugal force, thereby ensuring the cooling effect of the grinding wheel and the glass cover plate and the processing effect of the glass cover plate. In addition, the first guide groove 11 is not opened on the grinding wheel body 1, which also ensures the structural strength of the grinding wheel body 1.

[0023] Reference Figure 3The second guide groove 12 is a crescent-shaped arc groove, and the bending direction of the arc groove is consistent with the processing rotation direction of the grinding wheel body 1. The arc groove can reduce the resistance and impact of the coolant flowing in the second guide groove 12 when the grinding wheel body 1 rotates, making the flow of the coolant more stable and smooth.

[0024] Reference Figures 2 to 5 The second guide hole 13 includes a second upper guide hole 13a and a second lower guide hole 13b. The second upper guide hole 13a is a funnel-shaped hole with a larger upper portion and a smaller lower portion. The top diameter of the funnel-shaped hole is equal to that of the first guide hole 21, and the aperture of the second lower guide hole 13b is equal to that of the bottom diameter of the funnel-shaped hole. The bottom of the second lower guide hole 13b is circumferentially connected to an end of the second guide groove 12 close to the center of the grinding wheel body 1. The second guide hole 13 is divided into the second upper guide hole 13a and the second lower guide hole 13b, which can retain more of the internal structure of the grinding wheel body 1, thereby ensuring the structural strength of the grinding wheel body 1. The funnel-shaped second upper guide hole 13a can better guide the coolant to the second lower guide hole 13b.

[0025] Reference Figure 2-Figure 5 The grinding wheel body 1 is provided with a plurality of third guide holes 14 penetrating the first guide holes 21 and the second guide grooves 12, which can guide the coolant in the first guide holes 21 to the second guide grooves 12 more quickly and fully, and can also cool the upper part and the part close to the periphery of the grinding wheel body 1.

[0026] Reference Figure 2 In order to make it easier to process the grinding wheel body 1 and the flow inlet 2, the flow inlet 2 and the grinding wheel body 1 are split and detachably connected. In practical applications, a spiral connection can be used. This connection method can also enable the grinding wheel to continue working by simply replacing a new grinding wheel body 1 after the grinding wheel body 1 reaches its service life.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
