When chamfering the grinding wheels 8 of different thicknesses, start the third motor 52 to drive the vertical screw 53 to rotate. Since the rear portion of the movable block 55 is slidably mounted on the sliding column 54, the vertical screw 53 rotates so that the movable block 55 moves vertically on the vertical screw 53, driving the upper chamfering mechanism 6 to move vertically, thereby adjusting the vertical position of the chamfering end of the upper chamfering mechanism 6 until the chamfering end of the upper chamfering mechanism 6 can abut against the upper side of the grinding wheel 8. Since the grinding wheel 8 is horizontally clamped between the placement plate 32 and the clamping plate 33, the vertical position of the chamfering end of the upper chamfering mechanism 6 can be adjusted according to the grinding wheels 8 of different thicknesses, thereby performing chamfering processing on the grinding wheels 8 of different thicknesses.

When the grinding wheel 8 needs to be chamfered, the chamfering surface of the lower chamfering wheel 75 of the lower chamfering mechanism 7 is driven by the bidirectional chamfering drive mechanism 4 to abut against the lower side of the grinding wheel 8, and then the lower motor 73 is started to drive the lower transmission rod 74 to rotate, thereby driving the lower chamfering wheel 75 to rotate, so that the chamfering wheel and the lower side of the rotating grinding wheel 8 are chamfered, and the grinding efficiency is high. In this embodiment, since the connecting column 31 of the clamping mechanism 3 is vertically fixedly connected to the upper surface of the driven wheel, and the placing plate 32 is fixedly sleeved on the connecting column 31, when clamped and fixed, the inner hole of the grinding wheel 8 is sleeved on the connecting column The lower surface of the grinding wheel 8 is abutted against the upper surface of the placement plate 32, and the vertical position of the lower side of the grinding wheel 8 is fixed. When the lower side of the grinding wheel 8 is chamfered, only the lower chamfering mechanism 7 is driven horizontally by the bidirectional chamfering driving mechanism 4 to abut against the lower side for chamfering. For chamfering of grinding wheels 8 of different thicknesses, the upper chamfering mechanism 6 can be driven vertically by the vertical adjustment mechanism 5 to achieve chamfering of grinding wheels 8 of different thicknesses.

[0057] The working mode of the utility model is as follows:

[0058] When in use, before chamfering, the clamping plate 33 is separated from the placement plate 32. When the grinding wheel 8 needs to be chamfered, the inner hole of the grinding wheel 8 is sleeved on the connecting column 31, and the grinding wheel 8 is quickly positioned until the lower surface of the grinding wheel 8 abuts against the upper surface of the placement plate 32. Then, the thread of the threaded part is connected to the threaded hole 35 of the connecting column 31, and the clamping plate 33 and the screw rod 34 are rotated until the lower surface of the clamping plate 33 abuts against the upper surface of the grinding wheel 8, so that the screw rod 34 and the clamping plate 33 cooperate to fix the grinding wheel 8 between the placement plate 32 and the clamping plate 33.

[0059] By starting the first motor 21 to drive the rotating shaft 22 to rotate, the driving gear 23 is driven to rotate, the driving gear 23 drives the driven gear 24 to rotate, thereby driving the clamping mechanism 3 on the driven gear 24 to rotate, and then the grinding wheel 8 clamped by the clamping mechanism 3 is rotated;

[0060] The vertical position of the upper chamfering mechanism 6 is adjusted according to the different thicknesses of the grinding wheel 8, and the third motor 52 is started to drive the vertical lead screw 53 to rotate. Since the rear portion of the movable block 55 is slidably sleeved with the slide post 54, the vertical lead screw 53 rotates so that the movable block 55 moves vertically on the vertical lead screw 53, driving the upper chamfering mechanism 6 to move vertically, thereby adjusting the vertical position of the chamfering end of the upper chamfering mechanism 6 according to the thickness of the grinding wheel 8;

[0061] Then, the second motor 41 is started to drive the bidirectional screw 42 to rotate. With the cooperation of the left slider 45, the right slider 46 and the slide rod 47, the bidirectional screw 42 rotates to drive the left-handed nut 43 and the right-handed nut 44 threaded on the left-handed thread and the right-handed thread of the bidirectional screw 42 to move toward each other on the bidirectional screw 42 until the upper chamfering wheel 64 of the upper chamfering mechanism 6 and the lower chamfering wheel 75 of the lower chamfering mechanism 7 respectively abut against the upper side and lower side of the grinding wheel 8, and the upper motor 62 and the lower motor 73 are started at the same time to chamfer the upper side and lower side of the grinding wheel 8. Since the left-handed nut 43 and the right-handed nut 44 are symmetrically distributed on both sides of the driven gear 24, the upper chamfering mechanism 6 and the lower chamfering mechanism 7 can chamfer grinding wheels 8 of different diameters, and can chamfer the upper and lower sides of the grinding wheel 8 at the same time, without the need to manually turn over the grinding wheel 8, and the chamfering efficiency is higher.

[0062] Embodiment 2:

[0063] Embodiment 2 includes all the technical features of embodiment 1. The distinguishing features of embodiment 2 from embodiment 1 are as follows: a dust hood is provided on the rear side of the upper surface of the workbench 1, and a vacuum cleaner is connected to the rear side of the dust hood. The vacuum port of the dust hood faces forward to the vertical screw 53, the upper chamfering mechanism 6 and the lower chamfering mechanism 7. The grinding wheel 8, the vertical screw 53, the upper chamfering mechanism 6 and the lower chamfering mechanism 7 can fall into the vacuum range of the dust hood. When the vacuum cleaner is started, the waste chips generated during the chamfering process can be collected through the dust hood, so as to prevent the waste chips generated during the chamfering process from adhering to the vertical screw 53 and the bidirectional screw 42, so that the vertical screw 53 and the bidirectional screw 42 can work normally and the cleaning intensity is reduced.
