Description

Technical Field

[0001] The invention relates to the technical field of permanent magnet block grinding, in particular to a device for grinding the edge of an arc surface on a rare earth permanent magnet block. Background Art

[0002] The rare earth family consists of 15 elements from the lanthanide series and two elements closely related to the lanthanide series, scandium and yttrium. They are lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, scandium, and yttrium. Permanent magnets containing the above rare earth elements usually have stable magnetic properties. For this reason, rare earth permanent magnets are widely used in electronics, machinery and other industries due to their excellent performance.

[0003] The rare earth permanent magnet blocks in the prior art need to be polished on the upper arc surface, and in factories, large quantities of permanent magnet blocks need to be polished manually in coordination with machines, resulting in low polishing efficiency. At the same time, a large amount of debris and dust will be generated during the polishing process, which, if absorbed into the body, will affect the physical condition of the operator.

[0004] When applying for the present invention, the applicant found through search that a Chinese patent disclosed a "rare earth permanent magnet block upper arc edge grinding device", and its application number is "202223139100.1". The patent mainly limits, transports and grinds batches of rare earth permanent magnet blocks, greatly improving the work efficiency; on the other hand, by setting an arc groove on the limiting tube, it is ensured that the inner concave wheel accurately grinds the edges on both sides of the arc surface of the rare earth permanent magnet block in the arc groove, avoiding the damage of the equipment after the arc groove and the inner concave wheel contact, and ensuring that the rare earth permanent magnet block in the arc groove is smoothly polished. However, the specifications of the permanent magnet blocks in the patent are not uniform during the grinding process, which is not convenient for limiting the permanent magnet blocks of different sizes to complete the grinding operation. At the same time, the patent has fewer adjustment methods, which may cause limitations in the grinding process and may be inconvenient to use. Therefore, according to the applicant's invention, a rare earth permanent magnet block upper arc edge grinding device is invented, which solves the problem that a large number of permanent magnet blocks in the factory need to be manually polished with the cooperation of the machine, and the grinding efficiency is low.

The driving end of the first motor 2 is fixedly connected to the bidirectional screw 22;

[0035] The surface of the processing platform 1 is rollingly matched with a plurality of first conveying rollers 8 and second conveying rollers 16. By placing the permanent magnet block 15 through the opening at one end of the protective box body 1, the permanent magnet block 15 can be conveyed by rotating the first conveying roller 8 and the second conveying roller 16. The ends of the first conveying roller 8 and the second conveying roller 16 are fixedly connected with pulleys 19. The ends of the first conveying roller 8 and the second conveying roller 16 are sleeved with inner sleeve belts 18. The ends of the first conveying roller 8 and the second conveying roller 16 are connected by the inner sleeve belt 18 and the outer sleeve belt 17. Only one conveying roller 8 needs to be driven to drive the driving of the entire structure. The end of the inner belt 18 on one side is sleeved with an outer belt 17, and the middle part of the rear side of the processing platform 1 is fixedly connected to the second motor 7. After the second motor 7 is driven, the turntable 6 is driven to rotate, and after rotation, it is rotated with the rotating rod 30 to rotate and slide with the baffle 9, so as to block and convey the permanent magnet 15.

One end of the dust suction pipe 11 passes through the interior of the protective box body 12, and one end of the dust suction pipe 11 is fixedly connected to the dust hood.

[0036] Working principle: When in use, first place the permanent magnet block 15 through the opening at one end of the protective box 1, and then rotate the first conveying roller 8 and the second conveying roller 16 to convey the permanent magnet block 15. Since the ends of the first conveying roller 8 and the second conveying roller 16 are connected by the inner belt 18 and the outer belt 17, only one conveying roller 8 needs to be driven to drive the driving operation of the entire structure. During the driving process, the permanent magnet block 15 moves to the inside of the protective box 12, and the structure of the baffle 9 can block and limit the permanent magnet block 15, and can act at intervals. The conveying of the permanent magnet block 15 will be controlled. At this time, the second motor 7 drives the turntable 6 to rotate, and after rotating, it cooperates with the rotating rod 30 to rotate and slide with the baffle 9, thereby blocking and conveying the permanent magnet block 15. When the permanent magnet block 15 is conveyed and moved to the top of the induction pressure block 3, the induction pressure block 3 completes pressure sensing of the internal pressure sensor through the action of gravity, and the pressure sensor sends a signal to the controller after receiving the signal. After receiving the signal, the controller can send signals to the first motor 2 and the third motor 31 respectively. At this time, the first motor 2 can drive the bidirectional screw 22 rotates, and after rotation, it cooperates with the moving block thread, which can support the rotation support rod 20, move the clamping plate 21 inward, and fix the clamping of the permanent magnet block 15. After clamping, the third motor 31 is driven to drive the rotation of the grinding wheel 4. The servo motor 32 drives the rotation of the threaded rod to cooperate with the thread of the threaded block, so that the thread can be lowered. After lowering, the grinding operation of the upper arc surface can be completed by fitting the grinding wheel 4 and the permanent magnet block 15; by opening the top operation inspection plate 14 of the protective box body 12, the bolt 25 can be rotated in the opposite direction to move the outer grinding wheel 4 and the sliding shaft 23 are slidably matched, and then the threaded fastening is performed through the spiral threaded hole 24 to complete the sliding of the position to achieve precise adjustment control; when the dust generated during the grinding process can be started by the pump body 27, the interior of the dust box 29 is in a negative pressure state, and the dust hood at one end of the dust pipe 11 enters the gas, and the gas generating dust is adsorbed into the interior of the dust box 29, and falls into the interior of the collection box 26 by gravity for unified treatment; the permanent magnet block 15 after grinding can be pushed out of the induction pressing block 3 by the permanent magnet block 15 transported again at the rear end to complete the grinding operation.
