[0038] Example 2, reference Figure 3, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a sliding base 33, a first slider 34, a second slider 35, a first screw rod 36, a second screw rod 37, a component placement plate 38 and a lifting connecting plate 39, which can adjust the longitudinal position and vertical height of the grinding and chamfering assembly 3 to align the magnets at the first and second workstations and improve the chamfering accuracy.

The servo tapping machine can drive the chamfering tapping head 310 to rotate and can also adjust the distance from the discharge bin 52. By rotating the first turntable, the first screw 36 rotates, so that the first slider 34 drives the longitudinal position of the grinding bracket 31 to be adjusted. By rotating the second turntable, the second screw 37 rotates, so that the second slider 35 adjusts the vertical height of the lifting connecting plate 39 and the component placement plate 38, and thus the vertical height of the grinding bracket 31. This allows the pair of chamfering tapping heads 310 to be aligned with the magnets at the first and second workstations, respectively, to improve the accuracy of the chamfering of the magnet inner hole.

[0043] Preferably, a first reinforcement member 6 and a second reinforcement member 7 are respectively provided at the first station and the second station, and the first reinforcement member 6 and the second reinforcement member 7 are respectively fixed on the side of the first station and the second station away from the chamfering and tapping head 310;

[0045] Specifically, in this embodiment, by arranging the first reinforcement 6 and the second reinforcement 7 at the first work station and the second work station respectively, when a pair of chamfering tapping heads 310 chamfer the inner hole of the magnet, the first reinforcement 6 and the second reinforcement 7 support the discharge bin 52 at the positions of the first work station and the second work station respectively, thereby improving the overall structural strength of the discharge bin 52.

[0046] Preferably, Figure 2 As shown, the inclined downward pressing assembly 4 also includes a downward pressing guide rail 44, a downward pressing sliding block 45, a driving connecting plate 46, a downward pressing locking piece 47 and a downward pressing connecting piece 48.

The downward pressing connecting piece 48 is fixedly connected to the driving output end of the downward pressing driving component 42. The downward pressing plate 43 is fixed to the bottom of the downward pressing connecting piece 48.

[0047] Specifically, in this embodiment, the pressing connector 48 drives the pressing plate 43 to press downward, thereby pressing the magnets at the first station and the second station.

[0048] Preferably, the downward pressing driving component 42 is a dual-axis cylinder, and a sliding protrusion is provided on the side of the downward pressing driving component 42 away from the driving connecting plate 46 along the direction perpendicular to the discharge bin 52, and a sliding groove is provided on the inner side of the discharge connecting piece, and the sliding protrusion is slidably connected to the sliding groove.

[0049] Specifically, in this embodiment, the driving stability of the downward driving component 42 on the blanking connection piece is improved through the sliding connection between the sliding protrusion and the sliding groove.

[0050] Preferably, a pressing opening is provided at the lower end of the lower pressing plate 43 , the shape of the pressing opening is adapted to the shape of the magnet, and a buffer strip made of a flexible buffer material is provided at the lower end of the pressing opening.

[0051] Specifically, in this embodiment, the buffer strip can be made of silicone material. By providing the buffer strip, the magnet is prevented from being crushed, thereby improving the durability of the magnet.

[0052] Example 3, reference Figure 4, which is the third embodiment of the present invention.

[0054] The first transverse cylinder 82 and the second transverse cylinder 83 alternately drive the first stopper 84 and the second stopper 85 to alternately block the limiting groove and the end of the discharge chute.

[0055] Working principle of embodiment 3:

[0056] When several magnets fall into the discharge trough from the discharge end of the vibrating discharge component, since the first stop block 84 and the second stop block 85 alternately block the discharge trough front and back, the distance between the first stop block 84 and the second stop block 85 along the inclined falling direction of the magnet is consistent with the horizontal diameter of the magnet. Therefore, in the process of the first horizontal cylinder 82 and the second horizontal cylinder 83 alternately driving the first stop block 84 and the second stop block 85 to block the discharge trough, it is possible to complete the discharge of one magnet along the discharge trough at a time, thereby ensuring the accuracy and orderliness of the discharge.
