The grinding motor 42 starts to drive the grinding gear 41 to rotate and grind the gear to be processed.

[0046] Reference Figure 1 and Figure 3 After the installation of the gear to be processed and the position adjustment of the grinding gear 41 are completed, the driving cylinder 9 is started to drive the second side plate 8 to move along the length direction of the sliding groove 101, and the sliding block 81 slides in the sliding groove 101.

[0047] Reference Figure 3-5 When the grinding gear 41 grinds the gear to be processed, debris is generated. The metal debris is attracted by the arc-shaped electromagnet 3 and adsorbed on its inner arc wall, which reduces the impact of the debris on the processing of the gear to be processed. The driving motor 61 is started, and the driving rod 62 rotates under the drive of the driving motor 61. The sliding column 63 connected to the end of the driving rod 62 slides back and forth in the driving slide groove 661 of the reciprocating swing rod 66. The reciprocating swing rod 66 performs periodic reciprocating swings in a vertical plane with the rotating connecting rod 65 as the rotating axis 52 under the driving action of the sliding column 63. The rotating connecting rod 65 and the fan gear 64 reciprocate with the reciprocating swing rod 66, and the rotating gear 67 reciprocates under the drive of the fan gear 64. The rotating disk 51 reciprocates with the rotating gear 67.

[0048] Reference Figure 3 and Figure 4, the scraper block 54 connected to the rotating disk 51 by the first connecting rod 53 moves with the rotating disk 51, and the edge of the scraper block 54 pushes the debris adsorbed on the inner arc wall of the arc-shaped electromagnet 3 toward its end. The setting of the abutment pad 57 reduces the friction between the scraper block 54 and the arc-shaped electromagnet 3, reducing the possibility of damage to the arc-shaped electromagnet 3. When the scraper block 54 moves to the end of the arc-shaped electromagnet 3, the first connecting rod 53 presses it down along the inclined surface of the wedge-shaped electric control switch 59, and the electric control switch 59 sends an electrical signal to the control system (not shown in the figure), and the control system sends an electrical signal to the arc-shaped electromagnet 3 to disconnect and lose its magnetism. The top rod 58 pushes the slag collecting cover 552 toward the inside of the slag collecting box 55, and the debris pushed to the end of the arc-shaped electromagnet 3 falls into the slag collecting box 55 under the action of gravity. When the gear to be processed overheats during the grinding process, the cooling fan 23 starts and cools it, reducing the possibility of deformation of the gear to be processed due to heat.

[0049] Reference Figure 4 When the scraper block 54 slides in the reverse direction under the drive of the driving assembly 6, the slag collecting cover 552 is separated from the slag collecting cover 552, and the slag collecting cover 552 rotates in the reverse direction under the action of the torsion spring 553 and abuts against the limit block 554 to achieve reset. The setting of the torsion spring 553 realizes the closing of the slag collecting cover 552, and prevents the arc-shaped electromagnet 3 from sucking out the debris in the slag collecting box 55. The first connecting rod 53 is separated from the electric control switch 59, and the arc-shaped electromagnet 3 has magnetism again to absorb the debris, and the scraper block 54 moves in the reverse direction to push the debris, and the above operation is repeated to realize the collection and storage of the debris.

[0050] Reference Figure 5 and Figure 6 The driving motor 61 drives the driving pulley 13 to rotate, the driven pulley 14 rotates under the driving action of the transmission belt 15, and the transmission shaft 12 rotates with the driven pulley 14. The first connecting rod 16 rotates with the transmission shaft 12, and the second connecting rod 17 swings with the first connecting rod 16. The dust extraction slide bar 73 slides back and forth in the dust extraction cylinder 71 along the vertical direction, and the dust extraction plate 72 slides back and forth in the dust extraction cylinder 71. When the dust extraction plate 72 slides upward, the first one-way valve 78 is in an open state, and the second one-way valve 79 is in a closed state. Some non-magnetic impurities generated during processing are sucked into the dust extraction cylinder 71 through the dust collecting hopper 75 and the dust extraction pipe 74 for temporary storage. When the dust extraction plate 72 slides downward, the first one-way valve 78 is in a closed state, the second one-way valve 79 is in an open state, and the air with impurities in the dust extraction cylinder 71 is pushed into the dust collection box 77. The dust collection box 77 is provided with an air permeable net 18. The air overflows the dust collection box 77 through the air permeable net 18, and the impurities are temporarily stored in the dust collection box 77. The arrangement of the driving pulley 13, the driven pulley 14 and the transmission belt 15 realizes that the dust extraction plate 72 and the rotating gear 67 are driven by only one driving source.

[0051] The implementation principle of a grinding device for the tooth surface of a wind power gear in the embodiment of the present application is as follows: when grinding the gear, the gear to be processed is installed on the mounting shaft 46, and the position of the grinding gear 41 is adjusted. Debris is generated during the grinding process, and the debris is attracted by the arc-shaped electromagnet 3, thereby reducing the impact of the debris on the processing of the gear to be processed. Driven by the driving source, the scraper block 54 reciprocates along the inner arc wall of the arc-shaped electromagnet 3, and the edge of the scraper block 54 pushes the debris adsorbed on the arc-shaped electromagnet 3 into the slag collecting box 55 for collection.

[0052] The driving motor 61 is started, and the dust extraction plate 72 slides back and forth in the dust extraction cylinder 71. When the dust extraction plate 72 slides upward, some non-magnetic impurities generated are sucked into the dust extraction cylinder 71 through the dust extraction pipe 74 for temporary storage. When the dust extraction plate 72 slides downward, the air with impurities in the dust extraction cylinder 71 is pushed into the dust collection box 77 for storage.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
