After one side of the hexagonal nut 3 is polished and deburred, the electric push rod 12 is started to work. Through the cooperation of the gear 13 and the toothed plate 14, the two fixed rods 6 can be controlled to drive the two hexagonal nuts 3 to move in the direction away from the grinding disk 9. During the movement of the fixed rod 6, the gear ring 16 is driven to rotate in contact with the right-angle surface of the limited arc block 18 to control the hexagonal nut 3 to change the surface. When the electric push rod 12 is started again, the fixed rod 6 is controlled to drive the hexagonal nut 3 to move and reset, and the gear ring 16 contacts the arc surface of the limited arc block 18, pushing the limited arc block 18 into the slide groove 24, and the gear ring 16 does not rotate, which is convenient for timely changing the surface of the hexagonal nut 3 and removing burrs. The fixing rod 6 is provided with a fixing part and a pre-positioning part for fixing the hexagonal nut 3 on the outside, and a connecting part for pushing the fixing part to move is installed on one side of the grinding machine body 1. The fixing part includes a support plate 20 located on both sides of the fixing rod 6, and two connecting blocks 30 are fixedly installed at one end of the fixing rod 6. A first rotating rod 31 and a second rotating rod 23 are rotatably installed on the inner side of the supporting plate 20, and one end of the first rotating rod 31 is rotatably connected to the connecting block 30. The second rotating rod 23 is rotatably provided with a push rod 15 which is slidably connected to the fixed rod 6 at one end, and a mounting hole 19 is opened on the outer side of the fixed rod 6.

The fixed rod 6 continues to move, and the annular plate 10 contacts the oblique angle 7 of the push plate 8. The support plate 20 is separated from the inner side of the hexagonal nut 3 by the push of the connecting spring 17. At this time, it is convenient to remove the hexagonal nut 3 and replace it with a new hexagonal nut 3 for deburring. A controller 27 is fixedly mounted on one side of the grinding machine body 1 , and the controller 27 is electrically connected to the dual-axis motor 4 and the electric push rod 12 .

[0021] As a further technical solution of the present invention, the limiting member includes a plurality of arc-shaped limiting plates 21 fixedly mounted on the outside of the fixing rod 6. The arc-shaped limiting plates 21 are elastically arranged. A limiting groove 26 for limiting the arc-shaped limiting plates 21 is provided on the inner side of the collar 11. When the gear ring 16 contacts the right-angle surface of the limiting arc block 18 and rotates, the arc-shaped limiting plates 21 are squeezed when controlling the hexagonal nut 3 to change faces. When the gear ring 16 contacts the arc surface of the limiting arc block 18, the arc-shaped limiting plates 21 are limited by the limiting groove 26 to prevent the gear ring 16 from rotating at this time.

[0022] As a further technical solution of the present invention, the pre-positioning member includes two sliding openings 28 opened on the outside of the fixed rod 6, and an arc-shaped shell 22 is slidably connected in the sliding opening 28. A reset spring 29 is fixedly arranged between the arc-shaped shell 22 and the sliding opening 28. When taking and placing the hexagonal nut 3, any plane of the hexagonal nut 3 can be placed parallel to the grinding disk 9 (the equipment can simultaneously grind parts similar to the hexagonal nut 3, not only six sides, but also five sides and four sides, as long as one of the planes is controlled to be placed parallel to the grinding disk 9), and the hexagonal nut 3 is fixed by the arc-shaped shell 22 to avoid large movement of the hexagonal nut 3 during the movement.

[0023] Working principle: At this time, the annular plate 10 is located at the bevel 7 of the push plate 8, and the support plate 20 does not abut against the inner side of the hexagonal nut 3. The hexagonal nut 3 can be placed on the outer side of the fixing rod 6 (when placing it, any plane of the hexagonal nut 3 is placed parallel to the grinding disc 9). During the placing process, the arc-shaped shell 22 will be squeezed to move, and the reset spring 29 will be squeezed. The outer side of the arc-shaped shell 22 abuts against the inner side of the hexagonal nut 3, which is used to pre-fix the hexagonal nut 3 to prevent the hexagonal nut 3 from moving significantly during the subsequent movement process. Start the electric push rod 12 to work, drive the toothed plate 14 connected thereto to move, and through the cooperation between the gear 13 and the other toothed plate 14, the two collars 11 can be controlled to move, and the collars 11 drive the two hexagonal nuts 3 to move toward the direction of the grinding disc 9. During the movement, the fixing rod 6 drives the annular plate 10 to disengage from the bevel 7, and moves the plane of the straight push plate 8. The connecting spring 17 is squeezed, and the annular plate 10 pushes the push rod 15 to move, and the first rotating rod 31 and the second rotating rod 23 rotate, pushing the support plate 20 to abut against the inner side of the hexagonal nut 3, so as to fix the hexagonal nut 3; The electric push rod 12 continues to work, the fixed rod 6 continues to move, the fixed rod 6 drives the gear ring 16 to contact the arc surface of the limiting arc block 18, and pushes the limiting arc block 18 into the slide groove 24, and the gear ring 16 does not rotate (when the gear ring 16 contacts the arc surface of the limiting arc block 18, the arc limiting plate 21 is limited by the limiting groove 26 to prevent the gear ring 16 from rotating at this time), until the hexagonal nut 3 contacts the grinding disc 9, and the grinding disc 9 can grind and deburr it; After one side of the hexagonal nut 3 is polished and deburred, the electric push rod 12 is started to work. Through the cooperation of the gear 13 and the toothed plate 14, the two fixed rods 6 can be controlled to drive the two hexagonal nuts 3 to move in the direction away from the grinding disc 9. During the movement of the fixed rod 6, the gear ring 16 is driven to rotate in contact with the right-angled surface of the limiting arc block 18 to control the face change of the hexagonal nut 3 (the right-angled surface of the gear ring 16 and the limiting arc block 18 is rotated to control the face change of the hexagonal nut 3, and the arc limiting plate 21 is squeezed), and the electric push rod 12 is continued to be started to work, and then the fixed rod 6 is controlled to drive the hexagonal nut 3 to move and reset. The gear ring 16 contacts the arc surface of the limiting arc block 18, and the limiting arc block 18 is pushed into the slide groove 24. The gear ring 16 does not rotate, which is convenient for timely face change and deburring of the hexagonal nut 3; After the grinding work is completed, the electric push rod 12 is started to control the fixed rod 6 to move away from the grinding disk 9. The annular plate 10 first contacts the plane of the push plate 8. At this time, the support plate 20 is against the inner side of the hexagonal nut 3. The fixed rod 6 continues to move, and the annular plate 10 contacts the bevel 7 of the push plate 8. The support plate 20 is separated from the inner side of the hexagonal nut 3 through the push of the connecting spring 17. At this time, it is convenient to remove the hexagonal nut 3 and replace it with a new hexagonal nut 3 for deburring.
