DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0027] A NdFeB magnet chamfering device, such as Figure 1-Figure 4As shown, it includes a support frame 1, a rotating shaft 2, a discharge tray 3, a sealing gasket 32, a driving mechanism and a grinding mechanism. The support frame 1 is provided with two front and rear ones, and the rotating shaft 2 is rotatably connected between the middle parts of the two support frames 1. The discharge tray 3 is connected in the middle of the rotating shaft 2. The discharge tray 3 is provided with a plurality of accommodating grooves 31 and grooves 33 evenly spaced along the circumferential direction. The accommodating grooves 31 are connected to the grooves 33. The grooves 33 are used to clamp the magnets. The sealing gasket 32 ​​is provided on the grooves 33. A driving mechanism for driving the discharge tray 3 to rotate is provided between the discharge tray 3 and the support frame 1. A grinding mechanism for grinding the tile-shaped NdFeB magnet 100 is provided on the support frame 1.

[0028] like Figure 2 As shown, the driving mechanism includes an inner gear ring 41, a driving motor 42 and a driving gear 43. The inner gear ring 41 is connected to the discharge tray 3, and the driving motor 42 is installed on the rear support frame 1. The output shaft of the driving motor 42 is connected to the driving gear 43, and the driving gear 43 is meshed with the inner gear ring 41, so that the operation of the driving motor 42 can drive the discharge tray 3 to rotate through the driving gear 43 and the inner gear ring 41.

[0029] like Figure 2-Figure 4 As shown, the grinding mechanism includes a servo motor 51, a transmission shaft 52, a mounting frame 53, a spline shaft 1 54, a conical grinding wheel 55, a spline shaft 2 59, an adjustment component and a transmission component. The servo motor 51 is installed on the left side of the rear support frame 1, and the mounting frames 53 are slidably connected on the left sides of the two support frames 1. The transmission shaft 52 is rotatably connected between the two mounting frames 53. The front and rear sides of the transmission shaft 52 are connected to the spline shaft 1 54, and the output shaft of the servo motor 51 and the left side of the front support frame 1 are installed with the spline shaft 2 59. The two spline shafts 2 59 are located on the same axis. The spline shaft 1 54 and the spline shaft 2 59 are slidably connected with the conical grinding wheel 55. The support frame 1 is provided with an adjustment component for adjusting the position of the mounting frame 53, and a transmission component is provided between the transmission shaft 52 and the support frame 1.

[0030] like Figure 2-Figure 4 As shown, the adjustment component includes a side plate 56, a sliding plate 57 and an adjusting screw 58. The side plate 56 is connected between the left sides of the two support frames 1. The sliding plate 57 is slidably connected to the side plate 56. The sliding plate 57 is connected to the two mounting frames 53 so that the sliding plate 57 can drive the two mounting frames 53 to move when moving, so as to adjust the position of the conical grinding wheel 55. The side plate 56 is rotatably connected to the adjusting screw 58, and the adjusting screw 58 is threadedly matched with the sliding plate 57 so that the rotation of the adjusting screw 58 can drive the sliding plate 57 to move through the thread to adjust the position of the sliding plate 57.

[0031] like Figure 2-Figure 4As shown, the transmission assembly includes a slider 61, an elastic member 62, a pulley 63 and a transmission belt 64. The sliders 61 are slidably connected to the left sides of the two support frames 1. The sliders 61, the front and rear ends of the transmission shaft 52 and the front and rear spline shafts 59 are all connected with pulleys 63. The pulley 63 on the slider 61 is rotatably connected to the slider 61. A transmission belt 64 is wound between the three pulleys 63 on the front and rear sides. The pulley 63 and the transmission belt 64 form a triangle so that the spline shaft 59 and the transmission shaft 52 can rotate synchronously. An elastic member 62 is connected between the slider 61 and the support frame 1, and the elastic member 62 is a tension spring.

[0032] like Figure 5 and Figure 6 As shown, it also includes a fixing mechanism, which includes a cylinder 81, an air suction pipe 82, a connecting frame 83, a guide frame 84, a guide inclined rod 88, an elastic member 85, a T-shaped rod 86 and a piston plate 87. The discharge tray 3 is evenly spaced along the circumferential direction and connected with cylinders 81 of the same number as the receiving grooves 31. One end of the cylinder 81 is connected to the air suction pipe 82, and the air suction pipe 82 is connected to the receiving groove 31. The front and rear sides of the rotating shaft 2 are connected to the connecting frame 83. The connecting frame 83 is connected to a guide frame 84, and the guide frame 84 is arc-shaped. A slanted guide rod 88 is connected to the upper right side of the guide frame 84. A piston plate 87 is slidably connected in the cylinder body 81. An elastic member 85 is connected between the piston plate 87 and the cylinder body 81. The elastic member 85 is a return spring. A T-shaped rod 86 is connected to the piston plate 87. The guide frame 84 and the guide rod 88 are both located at the moving track of the T-shaped rod 86.

[0033] When the tile-shaped NdFeB magnet 100 needs to be chamfered, the tile-shaped NdFeB magnet 100 can be placed in the groove 33 first (the tile-shaped NdFeB magnet 100 processed in the present device is a semi-finished product and has not been magnetized, so it has no magnetism). Then, the driving motor 42 is controlled to operate to drive the discharge tray 3 to rotate through the driving gear 43 and the inner gear ring 41, thereby driving the cylinder body 81 and the T-shaped rod 86 to rotate. When the T-shaped rod 86 rotates, it will contact the guide inclined rod 88 and be squeezed by the guide inclined rod 88 to slide downward, thereby driving the piston plate 87 to move, the elastic member 85 is stretched, and the piston plate 87 moves. When the T-shaped NdFeB magnet 100 is moved, the gas in the receiving tank 31 is extracted through the suction pipe 82, so that negative pressure is generated in the receiving tank 31, and the tile-shaped NdFeB magnet 100 is fixed. Then, when the T-shaped rod 86 moves to the guide frame 84, the guide frame 84 presses against the T-shaped rod 86 to limit the T-shaped rod 86. Then, the tile-shaped NdFeB magnet 100 continues to move, so that the edges that need to be chamfered on the front and rear sides thereof are respectively in contact with the two conical grinding wheels 55 on the front and rear sides. Before that, the servo motor 51 can be controlled to operate through the transmission between the pulley 63 and the transmission belt 64 to drive the transmission shaft 52, the spline shaft 1 54 and the spline shaft 2 59 to rotate, so as to The conical grinding wheel 55 is driven to rotate, so that the conical grinding wheel 55 contacts the tile-shaped NdFeB magnet 100 during the rotation, and the edges of the front and rear sides of the tile-shaped NdFeB magnet 100 are ground and chamfered. In this way, the device can be used to chamfer the tile-shaped NdFeB magnet 100, and during the processing, the edges of the front and rear sides of the tile-shaped NdFeB magnet 100 are ground and chamfered by a roller-type conveying method. The chamfering can be performed while conveying, and the overall operation process is more continuous, and the front and rear sides can be processed at the same time, and the processing efficiency is higher. In the actual operation process, the adjusting screw 58 can be rotated according to the thickness of the tile-shaped NdFeB magnet 100, so that the sliding plate 57 can be driven to move left and right through the thread. When the sliding plate 57 moves, it can drive the mounting frame 53 and the transmission shaft 52 to move together, so as to adjust the spacing between the left and right conical grinding wheels 55 to adjust according to the thickness of the tile-shaped NdFeB magnet 100. When the transmission shaft 52 moves, it will drive the pulley 63 on it to move, thereby squeezing the pulley 63 on the slider 61 through the transmission belt 64, driving the slider 61 to move upward, and the elastic member 62 is compressed to ensure that the transmission belt 64 is tensioned.

[0034] like Figure 4 As shown, a locking bolt 72 is also included. The spline shaft 1 54 and the spline shaft 2 59 are both provided with a locking flat groove 71. The conical grinding wheel 55 is threadedly connected with the locking bolt 72. The locking bolt 72 can be rotated to move downward through the thread to press against the locking flat groove 71, thereby fixing the conical grinding wheel 55.

[0035] When using the present device, when it is necessary to adjust the size of the chamfer area, the locking bolt 72 can be removed, and then the conical grinding wheel 55 can be pulled to slide along the spline shaft 1 54 and the spline shaft 2 59 to adjust the size of the chamfer. The smaller the distance between the front and rear conical grinding wheels 55, the closer the conical grinding wheel 55 is to the tile-shaped NdFeB magnet 100, and the larger the chamfer area. Conversely, the larger the distance between the front and rear conical grinding wheels 55, the farther the conical grinding wheel 55 is to the tile-shaped NdFeB magnet 100, and the smaller the chamfer area, thereby playing a role in adjusting the size of the chamfer area.

[0036] like Figure 7 As shown, an isolation plate 9 is also included. The accommodating groove 31 is provided with an isolation plate 9. The isolation plate 9 is evenly spaced with air holes to disperse the suction force so that the suction force is evenly distributed at various positions of the tile-shaped NdFeB magnet 100, thereby avoiding the situation where the suction force is concentrated on one place of the tile-shaped NdFeB magnet 100, resulting in the tile-shaped NdFeB magnet 100 being over-pressed and broken.

[0037] like Figure 8 As shown, an arc-shaped shielding frame 10 is also included. The arc-shaped shielding frame 10 is connected between the right sides of the two support frames 1. The arc-shaped shielding frame 10 can cover the receiving groove 31 and the air intake pipe 82 to prevent dust from entering the receiving groove 31 and the air intake pipe 82.

[0038] like Figure 8 As shown, it also includes a connecting plate 11 and a belt conveyor group 12. Two connecting plates 11 are connected to the lower part of the two support frames 1. The belt conveyor group 12 is installed between the four connecting plates 11. The belt conveyor group 12 is evenly spaced with slag discharge holes. The polished tile-shaped NdFeB magnet 100 will fall on the belt conveyor group 12. The belt conveyor group 12 can be used to transport the tile-shaped NdFeB magnet 100. The debris generated during the polishing process falls on the belt conveyor group 12 and is discharged through the slag discharge holes on the belt conveyor group 12, so as to achieve the effect of processing the polished tile-shaped NdFeB magnet 100.

[0039] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
