It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figures 1 - 5As shown in the figure, the utility model provides a hole-opening device for grinding wheel processing, including: a base 1, a support column 2 fixedly connected to the top of the base 1, a first motor 3 fixedly connected to the inner top of the support column 2, the output end of the first motor 3 rotatably penetrating the outer surface of the support column 2, the output end of the first motor 3 fixedly connected to a turntable 4, a plurality of placing plates 5 fixedly connected to the top of the turntable 4 at equal intervals, and a support frame 6 fixedly connected to the position near the bottom of the inner surface of each of the plurality of placing plates 5; a drilling assembly 8, the drilling assembly 8 fixedly connected to the top of the base 1, the drilling assembly 8 including a mounting frame 801 and a bottom plate 807, the bottom of the mounting frame 801 fixedly connected to the top of the base 1, an electric telescopic rod 802 fixedly connected to the top of the mounting frame 801, the telescopic end of the electric telescopic rod 802 slidably penetrating the outer surface of the mounting frame 801, the telescopic end of the electric telescopic rod 802 fixedly connected to a connecting frame 803, a top plate 805 fixedly connected to the top of the connecting frame 803, a second motor 804 fixedly connected to the center of the top of the top plate 805, the output end of the second motor 804 rotatably penetrating the outer surface of the top plate 805, the output end of the second motor 804 fixedly connected to a drill bit 806, a plurality of springs 809 fixedly connected at equal intervals between the top plate 805 and the bottom plate 807, the bottom plate 807 being located below the top plate 805, a plurality of guide rods 808 fixedly connected to the top of the bottom plate 807 at equal intervals, the outer surfaces of the plurality of guide rods 808 all slidably penetrating the outer surface of the top plate 805 and extending upward, the second motor 804 being located inside the connecting frame 803, the guide rods 808 being located inside the springs 809, a fixing hole 810 being formed in the top of the bottom plate 807, the diameter of the fixing hole 810 being larger than the diameter of the drill bit 806, and a circular hole 7 being formed in the center of the top of the support frame 6, the diameter of the circular hole 7 being the same as the diameter of the fixing hole 810.

[0025] The effect achieved by the entire Embodiment 1 is that when machining the holes in the grinding wheel, the first motor 3 arranged at the inner top of the support column 2 is started. The output end of the first motor 3 drives the turntable 4 to rotate intermittently in the clockwise direction, so that it is located above the support frame 6. The diameter of the grinding wheel to be machined fits the inner surface of the placement plate 5, playing a role of preliminary positioning. Under the continuous rotation of the first motor 3, when the placement plate 5 equipped with the grinding wheel moves successively and stops below the drill bit 806, the second motor 804 is started. The output end of the second motor 804 drives the drill bit 806 to rotate rapidly. Meanwhile, the electric telescopic rod 802 is started, and its telescopic end drives the connecting frame 803 to move downward until the bottom of the bottom plate 807 fits and abuts against the lower grinding wheel. A plurality of guide rods 808 slide synchronously in the inner wall of the top plate 805, playing a role of positioning. A plurality of springs 809 are compressed when the bottom plate 807 is squeezed, and deform and contract between the top plate 805 and the bottom plate 807. At the same time, their resilience will force the bottom plate 807 to tightly abut against the grinding wheel, playing a role of abutting and fixing the grinding wheel. Under the continuous extension of the telescopic end of the electric telescopic rod 802, the rapidly rotating drill bit 806 passes through the fixing hole 810 and drills a hole in the center of the grinding wheel. After the hole opening is completed, the electric telescopic rod 802 drives the top plate 805 to rise and reset, and the bottom plate 807, the drill bit 806 and the grinding wheel are separated. The first motor 3 drives the turntable 4 to drive the next placement plate 5 to move below the drill bit 806, and the above-mentioned hole opening steps are repeated for hole opening. The operator stands at the opposite position of the mounting frame 801, and the operator takes out the grinding wheel with the hole opened in the nearest placement plate 5 in front of him and replaces it with a new grinding wheel. In this way, the drill bit 806 can quickly drill holes in multiple grinding wheels, greatly improving the hole opening efficiency of the grinding wheels.

[0026] Embodiment 2: As Figures 1 - 5 shown, a plurality of discharge holes 10 are equidistantly opened at the top of the turntable 4. The plurality of discharge holes 10 are respectively matched with the positions of the plurality of placement plates 5. The top of the base 1 is fixedly connected with a collecting ring block 9. An annular collecting groove is opened at the top of the collecting ring block 9. The inner surface of the collecting ring block 9 fits the outer surface of the support column 2.

[0027] The effect achieved by the entire Embodiment 2 is that when the drill bit 806 drills a hole in the grinding wheel during the hole opening of the grinding wheel, most of the generated debris falls downward through the circular hole 7 at the center of the support frame 6 and falls into the collecting ring block 9 through the discharge holes 10 for collection, playing a role of centralized collection and having high practicability.

[0028] Working principle: When machining the holes in the grinding wheel, start the first motor 3 installed at the top inside the support column 2. The output end of the first motor 3 drives the turntable 4 to rotate intermittently in the clockwise direction, so that it is above the support frame 6. The diameter of the grinding wheel to be machined fits against the inner surface of the placement disk 5, which plays a preliminary limiting role. Under the continuous rotation of the first motor 3, when the placement disk 5 with the grinding wheel moves successively and stops below the drill bit 806, start the second motor 804. The output end of the second motor 804 drives the drill bit 806 to rotate rapidly. Synchronously start the electric telescopic rod 802, and its telescopic end drives the connecting frame 803 to move downward until the bottom of the bottom plate 807 fits and abuts against the lower grinding wheel. Multiple guide rods 808 slide synchronously in the inner wall of the top plate 805, which plays a limiting role. Multiple springs 809 are compressed when the bottom plate 807 is pressed, and deform and contract between the top plate 805 and the bottom plate 807. At the same time, their resilience forces the bottom plate 807 to tightly abut against the grinding wheel, which plays a role in abutting and fixing the grinding wheel. Under the continuous extension of the telescopic end of the electric telescopic rod 802, the rapidly rotating drill bit 806 passes through the fixing hole 810 and drills a hole in the center of the grinding wheel. After the hole drilling is completed, the electric telescopic rod 802 drives the top plate 805 to rise and reset, and the bottom plate 807, the drill bit 806 and the grinding wheel are separated. The first motor 3 drives the next placement disk 5 to move below the drill bit 806, and repeat the above hole drilling steps to drill holes. The operator stands at the opposite position of the mounting frame 801, and the operator takes out the ground wheel with the hole drilled in the nearest placement disk 5 in front of him and replaces it with a new grinding wheel. In this way, the drill bit 806 can quickly drill holes in multiple grinding wheels, greatly improving the hole drilling efficiency of the grinding wheel. When drilling holes in the grinding wheel, most of the debris generated when the drill bit 806 drills holes in the grinding wheel falls downward through the round hole 7 at the center of the support frame 6 and falls into the collection ring block 9 through the discharge hole 10 for collection, which plays a role in centralized collection and has high practicability.

[0029] The above are only the preferred embodiments of the present invention, and do not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
