[0037] The working principle of the chamfering device for engine nut machining is as follows:

[0038] Firstly, when the engine nut 19 is placed in the inner wall of the positioning strip 18, the machine tool milling table 1 supports the positioning strip 18, and the positioning strip 18 supports the engine nut 19. At the same time, the machine tool milling table 1 supports the support rod 14, the support rod 14 supports the sleeved block 2, and the support rod 14 supports the support strip 13, thereby increasing the stability of the support strip 13. The support strip 13 supports the servo motor 4, thereby increasing the stability of the servo motor 4.

[0039] Secondly, the present application carries out two-way synchronous correction chamfering, the controller 12 starts the correction motor 7, the correction motor 7 drives the linkage screw rod 5 to rotate, the linkage screw rod 5 rotates inside the slot column 3, the linkage screw rod 5 drives two threaded sleeve blocks 6 to approach each other under the action of threaded transmission force. At the same time, the two threaded sleeve blocks 6 slide along the inner wall of the slot column 3 and approach each other, the threaded sleeve block 6 moves left, and the other threaded sleeve block 6 moves right. The threaded sleeve block 6 drives the slot 8 to move left, the slot 8 drives the strut 9 to move left, the strut 9 drives the correction groove roller 10 to move left, the correction groove roller 10 drives the distance sensor 11 to approach the right side of the engine nut 19, and the other distance sensor 11 approaches the left side of the engine nut 19. The distance sensor 11 senses the distance between the distance sensor 11 and the engine nut 19, when the distance value sensed by the distance sensor 11 is one centimeter set by the controller 12, the outer wall of the correction groove roller 10 is attached to the right side of the engine nut 19, and the outer wall of the other distance sensor 11 is attached to the left side of the engine nut 19. In this way, the horizontal offset position of the engine nut 19 is accurately corrected.

[0040] Then start the servo motor 4, the servo motor 4 drives the slot column 3 to rotate clockwise one hundred and eighty degrees, so that the slot column 3 drives the linkage screw rod 5 to rotate clockwise one hundred and eighty degrees, and the slot column 3 rotates clockwise one hundred and eighty degrees inside the sleeve block 2. The linkage screw rod 5 drives the two threaded sleeve blocks 6 to rotate clockwise one hundred and eighty degrees, and the two threaded sleeve blocks 6 respectively drive the two slots 8 to rotate clockwise one hundred and eighty degrees. The slot 8 drives the strut 9 to rotate clockwise one hundred and eighty degrees, the strut 9 drives the correction groove roller 10 to rotate clockwise one hundred and eighty degrees, and the correction groove roller 10 attached to the right side of the engine nut 19 rotates clockwise one hundred and eighty degrees, and the other correction groove roller 10 attached to the left side of the engine nut 19 rotates clockwise one hundred and eighty degrees. The two correction groove rollers 10 can accurately correct the horizontal position of the engine nut 19, and can also accurately correct the vertical position of the engine nut 19, so that the correction groove roller 10 can slide horizontally on the positioning strip 18 to correct the machining position from top to bottom.

[0041] Then, the present application carries out timely correction chamfering, when the correction groove roller 10 rotates 180 degrees clockwise, the correction groove roller 10 will rotate and extrude the guide head 24, since the outer wall of the guide head 24 is a chamfered surface, the correction groove roller 10 extrudes the guide head 24, the guide head 24 moves left under the action of the guide force, the guide head 24 drives the linkage column 23 to move left, the linkage column 23 drives the convex strip column 22 to move left, and the convex strip column 22 moves left along the inner wall of the sliding sleeve block 20, the convex strip column 22 drives the rubber pressing column 25 to move left and extrude, the rubber pressing column 25 extrudes the sensing end of the pressure sensor 26, the pressure sensor 26 is supported by the support block 21, and the pressure sensor 26 senses the pressure of the rubber pressing column 25. When the pressure sensor 26 senses the pressure value, it is known that the correction groove roller 10 has just completed the horizontal and vertical correction operation on the engine nut 19. At the same time, the controller 12 starts the down pressure cylinder 16, the down pressure cylinder 16 drives the pressing strip 17 to move down, and the pressing strip 17 extrudes the top of the engine nut 19, so that the engine nut 19 is fixed inside the positioning strip 18. At the same time when the two correction groove rollers 10 perform bidirectional correction on the engine nut 19, the pressing strip 17 can simultaneously fix the engine nut 19, avoiding the problem of deviation of the engine nut 19 during the fixing process. The engine nut 19 can be timely and automatically corrected and quickly fixed during milling, avoiding the deviation of the horizontal and vertical positions.

[0042] Finally, when the present application carries out distributed butt milling, the controller 12 starts two butt cylinders 27, which respectively push two sleeve sliding plates 28 to move close to each other, and the sleeve sliding plates 28 slide on the track 29. At the same time, the sleeve sliding plates 28 drive the supports 32 to move, the supports 32 drive the rotating motors 31 to move, the rotating motors 31 make the shafts 30 move, and the shafts 30 drive multiple chamfering knives 33 to move close to the right inner wall position of the engine nut 19, while the multiple chamfering knives 33 on the other shaft 30 move close to the left inner wall position of the engine nut 19. The controller 12 respectively starts the two rotating motors 31, which drive the shafts 30 to rotate, the shafts 30 drive the multiple chamfering knives 33 to rotate, and the multiple chamfering knives 33 contact and mill chamfering with the engine nut 19, so that the left and right multiple chamfering knives 33 can realize distributed butt milling on the two sides of the engine nut 19, and the protective cover 34 can realize protection operation on the debris.
