Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figures 1-5 The present invention provides a technical solution: a magnetic steel sheet grinding device, including a frame 1, on which two baffles 2 are fixedly arranged symmetrically; the grinding device also includes a material rack 3 for placing the tile-shaped magnetic steel sheet to be ground (hereinafter referred to as the tile-shaped magnetic steel sheet), the material rack 3 is detachably arranged on the two baffles 2, and the tile-shaped magnetic steel sheet is arranged in parallel in sequence in the material rack 3; a grinding component 4 is provided on the frame 1, the grinding component 4 is used to grind the inner ring surface of the tile-shaped magnetic steel sheet.

[0023] Specifically, the material rack 3 includes an arc-shaped support base 31, which is adapted to the tile-shaped magnetic steel sheet. The inner ring diameter of the arc-shaped support base 31 is equal to the outer ring diameter of the tile-shaped magnetic steel sheet, and as shown... Figure 3As shown, the tile-shaped magnetic steel sheets are neatly placed inside the arc-shaped support base 31, and both ends of the tile-shaped magnetic steel sheets are flush with two end faces of the arc-shaped support base 31. The material rack 3 also includes an arc-shaped stop block 1 32 and an arc-shaped stop block 2 33. The arc-shaped stop block 1 32 is fixed inside the arc-shaped support base 31, and the arc-shaped stop block 1 32 is coaxial with the arc-shaped support base 31, and the arc-shaped stop block 1 32 is adjacent to one end of the arc-shaped support base 31 in the length direction. The arc-shaped stop block 2 33 is movable and is adjacent to the other end of the arc-shaped support base 31 in the length direction. Multiple tile-shaped magnetic steel sheets are placed between the arc-shaped stop block 1 32 and the arc-shaped stop block 2 33. The distance between the arc-shaped stop block 1 32 and the arc-shaped stop block 2 33 is set to an integer multiple of the thickness of the tile-shaped magnetic steel sheets, so that multiple tile-shaped magnetic steel sheets are neatly placed between the arc-shaped stop block 1 32 and the arc-shaped stop block 2 33.

[0024] The inner ring diameters of both arc-shaped stop 1 32 and arc-shaped stop 2 33 are larger than the inner ring diameter of the tile-shaped magnetic steel sheet. An arc-shaped limiting block 37 is also fixedly installed on the outer ring surface of arc-shaped stop 2 33. The arc-shaped limiting block 37 is coaxial with arc-shaped stop 2 33, and the outer ring diameter of the arc-shaped limiting block 37 is equal to the inner ring diameter of the arc-shaped support 31. When the outer ring surface of the arc-shaped limiting block 37 contacts the inner ring surface of the arc-shaped support 31, arc-shaped stop 2 33 is coaxial with the arc-shaped support 31. In addition, when the tile-shaped magnetic steel sheet is placed between arc-shaped stop 1 32 and arc-shaped stop 2 33, arc-shaped stop 1 32 and arc-shaped stop 2 33 respectively contact the tile-shaped magnetic steel sheets located on the outermost sides. At the same time, the bottoms of the two stop bars 2 respectively contact the two ends of the tile-shaped magnetic steel sheet, but the distance between the two stop bars 2 is larger than the inner ring diameter of the tile-shaped magnetic steel sheet.

[0025] Four connecting studs 34 are fixedly installed on the arc-shaped support base 31, and the four connecting studs 34 are vertically arranged. Two through holes 21 are provided through each stop bar 2, so there are four through holes 21. The four through holes 21 are arranged in a one-to-one correspondence with the four connecting studs 34, and each connecting stud 34 passes through the corresponding through hole 21. A threaded sleeve 5 is also threadedly engaged on the outside of each connecting thread, and the bottom end of the threaded sleeve 5 abuts against the top surface of the stop bar 2. That is, by the engagement of the connecting studs 34 and the threaded sleeves 5, the material rack 3 is fixed on the two stop bars 2. At the same time, by unscrewing all the threaded sleeves 5, the material rack 3 can be separated from the stop bars 2.

[0026] A support shaft 36 is provided on the arc-shaped support base, and the support shaft 36 is movably mounted on the arc-shaped support base 31 via bearings; a fixing seat 35 is fixedly sleeved on the outside of the support shaft 36, and the fixing seat 35 is fixedly connected to the arc-shaped stop bar 2; before the material rack 3 is connected to the stop bar 2, the arc-shaped limiting block 37 contacts the arc-shaped support base 31, and then the arc-shaped support base 31 contacts the two stop bars 2, so that the bottom of one of the stop bars 2 abuts against the end of the arc-shaped stop block 33 away from the fixing seat 35, and at the same time, the four connecting studs 34 pass through the four through holes 21 respectively. Finally, by tightening each threaded sleeve 5, the material rack 3 is fixed on the arc-shaped support base 31, and the tile-shaped magnet is stably limited in the material rack 3; when the material rack 3 is separated from the stop bar 2, the arc-shaped stop block 33 and the fixing seat 35 can rotate around the support shaft 36; when the arc-shaped stop block 33 rotates to such a position... Figure 4 When in the indicated state, the tile-shaped magnet sheet can be easily placed or removed.

[0027] The grinding assembly 4 includes a support frame 41 movably mounted on the frame 1, which can move up and down; a grinding roller 42 is rotatably mounted on the support frame 41, with both ends of the grinding roller 42 movably connected to the support frame 41 via bearings; a drive motor 44 is mounted on the support frame 41, and the output shaft of the drive motor 44 is fixedly connected to one end of the grinding roller 42, with the output shaft of the drive motor 44 coaxial with the grinding roller 42; the grinding assembly 4 also includes a lifting mechanism 43, which is used to drive the support frame 41 to move up and down; Figure 1 As shown, in the initial state, the axis of the grinding roller 42 is directly above the axis of the arc-shaped support 31, and the grinding roller 42 is adapted to the inner ring of the tile-shaped magnet. The lifting mechanism 43 drives the support frame 41 and the grinding roller 42 to descend. When the grinding roller 42 contacts the inner ring of the tile-shaped magnet, the drive motor 44 drives the grinding roller 42 to rotate, thus grinding all the inner rings of the tile-shaped magnets. Figure 5 As shown in the diagram; after a suitable grinding time, the support frame 41 and grinding roller 42 are reset by the lifting mechanism 43. At this time, the debris can be cleaned by an external blowing device or a cleaning brush. After cleaning, the support frame 41 and grinding roller 42 are lowered again by the lifting mechanism 43, and the grinding roller 42 is rotated and ground again by the drive motor 44. After several cleaning and grinding operations, the grinding operation of the inner ring of the tile-shaped magnetic steel sheet can be completed.

[0028] After the grinding is completed, the lifting mechanism 43 drives the support frame 41 to reset. By unscrewing all the threaded sleeves 5, the material rack 3 is separated from the stop bar 2. By rotating the arc-shaped stop block 33, each tile-shaped magnetic steel sheet can be easily removed. The tile-shaped magnetic steel sheets can then be further ground by other external devices.

[0029] In this embodiment, the inner ring surfaces of multiple tile-shaped magnetic steel sheets can be polished simultaneously; by setting up a material rack 3, which is detachably mounted on the baffle 2, the tile-shaped magnetic steel sheets can be conveniently placed or removed when the material rack 3 is separated from the baffle 2.
