Description

Technical Field

[0002] In recent years, NdFeB magnets, as a sunrise industry of energy conservation and environmental protection, have been widely used in information technology, automobiles, nuclear magnetic resonance, wind power generation, motors and other fields. In the processing of NdFeB magnets, in order to ensure the smoothness of their surface, they need to be ground. Therefore, it is necessary to use such positioning devices to clamp and position the NdFeB magnets to prevent them from shaking during processing. However, the NdFeB magnet production and processing equipment in the prior art has the following defects:

[0003] In the prior art, when NdFeB magnet production and processing equipment is grinding NdFeB magnet plates, it is necessary to grind the upper and lower end surfaces of the NdFeB magnet plates, so that the NdFeB magnet plates need to be flipped. However, in the process of clamping and flipping the two sides of the NdFeB magnet plates by the existing clamping assembly, it is easy to cause the NdFeB magnet plates to shift during the flipping process, so that the staff needs to re-position, clamp and fix them, which affects the effect of NdFeB magnet production and processing;

[0004] In the prior art, when the NdFeB magnet production and processing equipment is grinding the NdFeB magnet plate, in order to prevent the NdFeB magnet plate from moving downward, it is necessary to support the lower side of the NdFeB magnet plate. However, after the NdFeB magnet plate is turned over, the support structure is located on the end surface of the NdFeB magnet plate, thereby affecting the effect of the grinding process on the end surface of the NdFeB magnet plate.

[0005] In the prior art, the clamping assembly in the NdFeB magnet production and processing equipment lacks a limiting structure. During the end surface grinding process of the NdFeB magnet plate, the clamping assembly is prone to displacement or loosening, thereby affecting the effect of the end surface grinding process of the NdFeB magnet plate.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention discloses a NdFeB magnet production and processing equipment and a processing technology thereof. Through the arrangement of a frame, a first L-shaped block, a second L-shaped block, a first rubber block and a second rubber block, two frames are brought close to each other to drive two first L-shaped blocks and two second L-shaped blocks to approach each other. The two first L-shaped blocks and two second L-shaped blocks are brought close to each other to drive two groups of first rubber blocks and two groups of second rubber blocks to approach each other and to be in extrusion contact with two sides of a NdFeB magnet sheet, so that the two sides of the NdFeB magnet sheet are clamped and fixed by a plurality of first rubber blocks and second rubber blocks, and the two sides of the NdFeB magnet sheet are respectively located on the upper side of one end of the two first L-shaped blocks, so that the NdFeB magnet sheet is supported by one end of the two first L-shaped blocks, the NdFeB magnet sheet is prevented from moving downward, and the effect of limiting and fixing the NdFeB magnet sheet is improved. Then, through the arrangement of the annular member, the first top plate, the first movable block, the first connecting plate, the second connecting plate, the first push rod, and the second push rod, the second disc rotates to drive the first top plate and the second top plate to rotate, and the distance between the lower side of the second disc and the inner lower side of the annular member is smaller than the distance between the upper side of the second disc and the inner upper side of the annular member, and under the elastic force of the first spring and the second spring, the other ends of the first top plate and the second top plate are always in sliding contact with the inner side of the annular member, so that the rotation of the first top plate and the second top plate is guided by the inner side of the annular member, so as to facilitate the first top plate and the first movable block to move to one side. The movement of the first top plate drives the movement of the first top plate through the first connecting plate, and the movement of the first push rod drives the first L-shaped block to move toward the inside of the frame. The movement of the second top plate drives the second push rod to move through the second connecting plate, and the movement of the second push rod drives the second L-shaped block to move toward the outside of the frame, so that after the NdFeB magnetic steel sheet is turned over, the first L-shaped block moves into the interior of the frame and the second L-shaped block moves out of the frame, so that the lower side of the NdFeB magnetic steel sheet can be supported by the two second L-shaped blocks, and the two first L-shaped blocks can be prevented from affecting the effect of the end surface grinding of the NdFeB magnetic steel sheet.

[0026] The present invention provides a NdFeB magnet production and processing equipment and a processing technology thereof. Through the arrangement of the first hollow piece, the second hollow piece, the third hollow piece, the fourth hollow piece, the first elastic connecting tube, and the second elastic connecting tube, the first L-shaped block moves toward the inside of the frame to squeeze and compress the third hollow piece, so that the solution in the third hollow piece enters the first hollow piece through the first elastic connecting tube, so that the first hollow piece expands and squeezes the first rubber block to remain motionless. The second L-shaped block moves toward the outside of the frame, and the fourth hollow piece recovers its shape under the action of elastic force, so that the solution in the second hollow piece is sucked back into the fourth hollow piece through the second elastic connecting tube, so that the second hollow piece shrinks and recovers its original shape, so as to maintain the position of the second rubber block, avoid the displacement of the first rubber block and the second rubber block during the process of turning over the NdFeB magnet plate, and prevent the displacement of the NdFeB magnet plate during the process of turning over, which is conducive to the smooth turning over of the NdFeB magnet plate.

[0027] The present invention provides a NdFeB magnet production and processing equipment and its processing technology. Through the arrangement of a block, a third spring, a second movable plate, and a slot, the two first top plates approach each other to drive the two blocks to approach each other. Through one side of the block contacts the inclined surface of one side of the slot, the block moves and is squeezed by the second movable plate, so that the block slides in the first top plate. The sliding of the block compresses the third spring to generate elastic force. The elastic force of the third spring acts on the block so that the third spring is always in contact with the upper side of the second movable plate. Then, through the other side of the block contacts the other side plane of the slot, the second disc is limited and fixed to avoid displacement of the second disc. Then, through the arrangement of bolts and T-blocks, the staff rotates the bolts to drive the T-blocks to rotate. Through the contact of the bolts with the lower thread of the annular member and the rotation of the T-block in the second movable plate, the second movable plate moves downward and is out of contact with the block, so as to clamp and fix the new NdFeB magnet plate. Finally, by setting the elastic protrusions, a plurality of elastic protrusions are distributed in a circular array inside the annular member, so as to limit the first top plate and the second top plate in the circumferential direction, and further limit and fix the second disc to avoid the displacement and loosening of the clamping assembly.

[0064] First, the staff placed the NdFeB magnetic steel plate on the upper side of one end of the two first L-shaped blocks 28, and the staff operated the clamping assembly to start, and the two second electric telescopic rods 22 extended to drive the two second discs 24 to move closer to each other, and the two second discs 24 moved closer to each other to drive the two frames 25 to move closer to each other, and the two frames 25 moved closer to each other to drive the two first L-shaped blocks 28 and the two second L-shaped blocks 29 to move closer to each other, and the two first L-shaped blocks 28 and the two second L-shaped blocks 29 moved closer to each other to drive the two sets of first rubber blocks 30 The two groups of second rubber blocks 31 are close to each other and squeezed into contact with the two sides of the NdFeB magnetic steel sheet, so that the two sides of the NdFeB magnetic steel sheet are clamped and fixed by the first rubber blocks 30 and the second rubber blocks 31, and the two sides of the NdFeB magnetic steel sheet are respectively located on the upper side of one end of the two first L-shaped blocks 28, so that the NdFeB magnetic steel sheet is supported by one end of the two first L-shaped blocks 28 to prevent the NdFeB magnetic steel sheet from moving downward, thereby improving the effect of limiting and fixing the NdFeB magnetic steel sheet. The two second disks 24 approach each other, driving the two first top plates 39 to approach each other, and the two first top plates 39 approach each other, driving the two clamping blocks 48 to approach each other, and through one side of the clamping block 48 contacting the inclined surface of one side of the clamping slot 51, the clamping block 48 moves and is squeezed by the second movable plate 50, so that the clamping block 48 slides in the first top plate 39, and the sliding of the clamping block 48 compresses the third spring 49 to generate elastic force, and the elastic force of the third spring 49 acts on the clamping block 48, so that the third spring 49 is always in contact with the upper side of the second movable plate 50. Then, through the other side of the clamping block 48 contacting the other side plane of the clamping slot 51, the second disk 24 is limited and fixed to prevent the second disk 24 from displacement. Finally, the staff rotates the bolt 53 to drive the T-block 54 to rotate, and the bolt 53 contacts the lower thread of the ring 26 and the T-block 54 rotates and contacts in the second movable plate 50, so that the second movable plate 50 moves downward and disengages from the clamping block 48, so as to clamp and fix the new NdFeB magnetic steel plate.

[0065] Then, the first electric telescopic rod 15 extends to drive the first movable plate 16 and the first stepping motor 17 to move downward, and the first movable plate 16 moves downward to drive the grinding plate 18 to move downward, and the grinding plate 18 moves downward to contact the end face of the NdFeB magnetic steel plate. Then the first stepping motor 17 starts to drive the grinding plate 18 to rotate, and the grinding plate 18 rotates to grind the end face of the NdFeB magnetic steel plate. After the grinding process of one end face of the NdFeB magnetic steel plate is completed, it is necessary to grind the other end face of the NdFeB magnetic steel plate. The first stepping motor 17 stops, and the first electric telescopic rod 15 contracts to drive the first movable plate 16 and the grinding plate 18 to move upward, and the grinding plate 18 moves upward to break contact with the NdFeB magnetic steel plate.

[0066] Next, the two second stepper motors 23 are started to drive the two second gears 56 to rotate, and the outer side of the first gear 55 is meshed with the outer side of the second gear 56, and the two second gears 56 rotate to drive the two rotating blocks 21 and the two second electric telescopic rods 22 to rotate, and the two second electric telescopic rods 22 rotate to drive the two second discs 24 to rotate. The rotation of the two second discs 24 drives the two frames 25 to rotate, and the rotation of the two frames 25 turns over the NdFeB magnetic steel plate. During the turning over of the NdFeB magnetic steel plate, the second disc 24 rotates to drive the first top plate 39 and the second top plate 44 to rotate, and the distance between the lower side of the second disc 24 and the lower side of the inner part of the ring 26 is smaller than the distance between the upper side of the second disc 24 and the upper side of the inner part of the ring 26, and under the elastic force of the first spring 41 and the second spring 46, the other ends of the first top plate 39 and the second top plate 44 are always in sliding contact with the inner side of the ring 26, so that the rotation of the first top plate 39 and the second top plate 44 is guided by the inner side of the ring 26, so that the first top plate 39 and the first movable block 40 move to one side. The movement of the first top plate 39 drives the first top plate 39 to move through the first connecting plate 42, and the movement of the first push rod 38 drives the first L-shaped block 28 to move toward the inside of the frame 25. The second top plate 44 moves through the second connecting plate 47 to drive the second push rod 43 to move, and the second push rod 43 moves to drive the second L-shaped block 29 to move to the outside of the frame 25, so that after the NdFeB magnetic steel sheet is turned over, the first L-shaped block 28 moves into the interior of the frame 25 and the second L-shaped block 29 moves out of the frame 25, so that the lower side of the NdFeB magnetic steel sheet can be supported by the two second L-shaped blocks 29, and the two first L-shaped blocks 28 can be prevented from affecting the effect of the end surface grinding of the NdFeB magnetic steel sheet.

[0067] At the same time, the first L-shaped block 28 moves toward the inside of the frame 25 to squeeze and compress the third hollow piece 34, so that the solution in the third hollow piece 34 enters the first hollow piece 32 through the first elastic connecting tube 36, so that the first hollow piece 32 expands and squeezes the first rubber block 30 to remain motionless. The second L-shaped block 29 moves toward the outside of the frame 25, and the fourth hollow piece 35 recovers its shape under the action of elastic force, so that the solution in the second hollow piece 33 is sucked back into the fourth hollow piece 35 through the second elastic connecting tube 37, so that the second hollow piece 33 shrinks and recovers its original shape, so as to maintain the position of the second rubber block 31, and avoids the displacement of the first rubber block 30 and the second rubber block 31 during the flipping process of the NdFeB magnetic steel plate, and prevents the displacement of the NdFeB magnetic steel plate during the flipping process.

[0068] Finally, the first electric telescopic rod 15 extends to drive the first movable plate 16 and the first stepping motor 17 to move downward, and the first movable plate 16 moves downward to drive the grinding plate 18 to move downward, and the grinding plate 18 moves downward to contact the end surface of the NdFeB magnetic steel plate. Then the first stepping motor 17 starts to drive the grinding plate 18 to rotate, and the grinding plate 18 rotates to grind the end surface of the NdFeB magnetic steel plate.

The two first L-shaped blocks 28 and the two second L-shaped blocks 29 are brought close to each other to drive the two groups of first rubber blocks 30 and the two groups of second rubber blocks 31 to be close to each other and to be in extrusion contact with the two sides of the NdFeB magnet sheet, so that the two sides of the NdFeB magnet sheet are clamped and fixed by a plurality of first rubber blocks 30 and second rubber blocks 31, and the two sides of the NdFeB magnet sheet are respectively located on the upper side of one end of the two first L-shaped blocks 28, so that the NdFeB magnet sheet is supported by one end of the two first L-shaped blocks 28, so that the NdFeB magnet sheet is prevented from moving downward, and the effect of limiting and fixing the NdFeB magnet sheet is improved. Then, through the arrangement of the annular member 26, the first top plate 39, the first movable block 40, the first connecting plate 42, the second connecting plate 47, the first push rod 38, and the second push rod 43, the second disc 24 rotates to drive the first top plate 39 and the second top plate 44 to rotate, and the distance between the lower side of the second disc 24 and the inner lower side of the annular member 26 is smaller than the distance between the upper side of the second disc 24 and the inner upper side of the annular member 26, and under the elastic force of the first spring 41 and the second spring 46, the other ends of the first top plate 39 and the second top plate 44 are always in sliding contact with the inner side of the annular member 26, so that the rotation of the first top plate 39 and the second top plate 44 is guided by the inner side of the annular member 26, so that the first top plate 39 and the first movable block 40 move to one side. The movement of the first top plate 39 drives the first top plate 39 to move through the first connecting plate 42, and the movement of the first push rod 38 drives the first L-shaped block 28 to move toward the inside of the frame 25. The second top plate 44 moves through the second connecting plate 47 to drive the second push rod 43 to move, and the second push rod 43 moves to drive the second L-shaped block 29 to move to the outside of the frame 25, so that after the NdFeB magnetic steel sheet is turned over, the first L-shaped block 28 moves into the interior of the frame 25 and the second L-shaped block 29 moves out of the frame 25, so that the lower side of the NdFeB magnetic steel sheet can be supported by the two second L-shaped blocks 29, and the two first L-shaped blocks 28 can be prevented from affecting the effect of the end surface grinding of the NdFeB magnetic steel sheet.

[0070] The present invention provides a NdFeB magnet production and processing equipment and a processing technology thereof. Through the arrangement of the first hollow piece 32, the second hollow piece 33, the third hollow piece 34, the fourth hollow piece 35, the first elastic connecting tube 36, and the second elastic connecting tube 37, the first L-shaped block 28 moves toward the inside of the frame 25 to squeeze and compress the third hollow piece 34, so that the solution in the third hollow piece 34 enters the first hollow piece 32 through the first elastic connecting tube 36, so that the first hollow piece 32 expands and squeezes the first rubber block 30 to keep it stationary. The second L-shaped block 29 moves to the outside of the frame 25, and the fourth hollow member 35 recovers its shape under the action of elastic force, so that the solution in the second hollow member 33 is sucked back into the fourth hollow member 35 through the second elastic connecting tube 37, so that the second hollow member 33 shrinks and recovers its original shape, so as to maintain the position of the second rubber block 31, avoid the displacement of the first rubber block 30 and the second rubber block 31 during the flipping of the NdFeB magnetic steel plate, prevent the displacement of the NdFeB magnetic steel plate during the flipping process, and facilitate the smooth flipping of the NdFeB magnetic steel plate.

[0071] The present invention provides a NdFeB magnet production and processing equipment and a processing technology thereof. Through the arrangement of a clamping block 48, a third spring 49, a second movable plate 50, and a clamping slot 51, the two first top plates 39 are brought close to each other to drive the two clamping blocks 48 to be close to each other. Through one side of the clamping block 48 contacting with the inclined surface of one side of the clamping slot 51, the clamping block 48 moves and is squeezed by the second movable plate 50, so that the clamping block 48 slides in the first top plate 39. The sliding of the clamping block 48 compresses the third spring 49 to generate an elastic force. The elastic force of the third spring 49 acts on the clamping block 48 so that the third spring 49 is always in contact with the upper side of the second movable plate 50. Then, through the other side of the clamping block 48 contacting with the other side plane of the clamping slot 51, the second disc 24 is limited and fixed to avoid displacement of the second disc 24. Then, by setting the bolt 53 and the T-block 54, the staff rotates the bolt 53 to drive the T-block 54 to rotate, and the bolt 53 contacts the lower thread of the ring 26 and the T-block 54 rotates and contacts in the second movable plate 50, so that the second movable plate 50 moves downward and disengages from the clamping block 48, so as to clamp and fix the new NdFeB magnetic steel plate. Finally, by setting the elastic protrusion 27, a plurality of elastic protrusions 27 are distributed in a circumferential array inside the ring 26, so as to limit the first top plate 39 and the second top plate 44 in the circumferential direction, and further limit and fix the second disc 24, so as to avoid the situation where the clamping assembly is displaced and loosened.
