[0003] When processing the countersunk nut in the nut, it is necessary to chamfer the outer wall opening and the inner wall opening of the countersunk nut. In the countersunk nut chamfering device in the prior art, the countersunk nut is first clamped by a three-jaw chuck, and then the cylinder is used to move the turning tool to the outside of the nut. At this time, the turning tool is rotated by the power mechanism to complete the chamfering of the outer wall opening of the countersunk nut, and then the three-jaw chuck is loosened, and then the countersunk nut is turned over so that the unprocessed side is on the outside, and then the above operation is repeated again to chamfer both sides of the countersunk nut.

[0004] In the prior art, after processing one side of the countersunk nut, it is necessary to take the countersunk nut out of the clamping device, then turn the countersunk nut over and clamp it again, then chamfer the countersunk nut again with a turning tool, so as to chamfer the outer walls on both sides of the countersunk nut, then repeat the above operations, and at the same time switch the turning tool to chamfer the inner wall of the countersunk nut.

[0063] The working principle of the present invention is as follows: when it is necessary to chamfer the hexagonal countersunk nut, first place the countersunk nut to be processed inside the feed port 3, then start the external motor of the feeding mechanism 4 to rotate the first rotating shaft 4031, and through the transmission connection between the first rotating shaft 4031, the first gear 4032 and the second transmission belt 4033, the second transmission belt 4033 is transmitted, so that the first transmission belt 402 is synchronously transmitted. At this time, the countersunk nut falls into the first spring telescopic rod 4051 by its own gravity, and the first transmission belt 402 drives the countersunk nut to move to the bottom of the first transmission belt 402. During the movement, the countersunk nut exposed on the outside of the first spring telescopic rod 4051 is squeezed by the inner wall of the first transmission belt 402, so that the hexagonal countersunk nut fits with the first spring telescopic rod 4051 until the countersunk nut moves to the bottom of the first transmission belt 402.

[0064] Furthermore, when the first rotating shaft 4031 rotates, the third transmission belt 4041 drives the second gear 4042 to transmit, so that the second rotating shaft 5031 rotates. Through the transmission connection between the second rotating shaft 5031, the third gear 5032 and the fifth transmission belt 5033, the fifth transmission belt 5033 drives the fourth transmission belt 502 to transmit, ensuring that the second clamping block 5042 with the opening upward is aligned with the first clamping block 4052 facing downward. At this time, the countersunk nut is limited to the middle of the second clamping block 5042 and the first clamping block 4052 through the fit between the second clamping block 5042 and the first clamping block 4052, and the external motor of the first rotating shaft 4031 is stopped.

[0065] Further, the cylinder 601 is started so that the cylinder 601 pushes the power mechanism 602 to move, so that the first cutting mechanism 603 drives the second cutting mechanism 604 to move horizontally, and the motor 6021 is started at the same time, so that the first collecting pipe 6031 rotates, and the first collecting pipe 6031 and the second collecting pipe 6041 are fixedly connected with each other and the connecting rod 6033, so that the first collecting pipe 6031 and the second collecting pipe 6041 rotate synchronously, and when the first collecting pipe 6031 and the second collecting pipe 6041 continue to move toward the direction of the countersunk nut, the first collecting pipe 6031 contacts the outer wall of the countersunk nut, thereby chamfering the outer wall of the countersunk nut, and at the same time, the second cutting knife 6042 contacts the inner wall of the countersunk nut, thereby completing the chamfering of the inner wall of the countersunk nut;

[0066] Furthermore, when the second collecting pipe 6041 chamfers the inner wall of the countersunk nut, the debris cut by the second cutting knife 6042 falls from the through slot at the end of the second collecting pipe 6041 into the interior of the second collecting pipe 6041. At this time, the continuous start-up of the motor 6021 causes the third rotating shaft 6022 to drive the fan blade 6023 to rotate continuously, thereby generating suction on the inner wall of the second collecting pipe 6041, ensuring that the debris inside the second collecting pipe 6041 is sucked to the other end of the second collecting pipe 6041. At this time, the debris inside the second collecting pipe 6041 falls between the second collecting pipe 6041 and the first collecting pipe 6031 through the through slot at the other end of the second collecting pipe 6041. At the same time, when the fan blade 6023 continues to generate suction, the first cutting knife 603 2 The debris generated by cutting is absorbed into the other end of the first collecting pipe 6031 until it is collected into the waste bin 6034. After long-term use, the debris inside the waste bin 6034 is taken out by disassembling the waste bin 6034 and the first collecting pipe 6031 connected by bolts. When the first collecting pipe 6031 moves toward the countersunk nut with the cylinder 601, the electromagnetic rod 6043 is powered on, so that the electromagnetic rod 6043 generates magnetic force, ensuring that larger cutting debris is absorbed by the electromagnetic rod 6043. When the first collecting pipe 6031 is reset to the initial position, the electromagnetic rod 6043 is powered off, so that the electromagnetic rod 6043 loses its magnetic force, and the larger debris absorbed by the electromagnetic rod 6043 falls off, thereby completing the chamfering of the countersunk nut.
