[0026] The position push plate 37 is pushed by the end of the spring. The pressure-sensitive detector between the position push plate 37 and the end face of the detection seat 35 is composed of a pressure spring 38 and a pressure-sensitive sensor. When the position push plate 37 is pushed by the end of the spring, the pressure spring 38 is compressed, and the pressure-sensitive sensor outputs a pressure signal and feeds it back to the analysis system to correct and adjust the cutting position of the end of the spring. A rotating plate motor 43 is fixedly arranged on the mounting plate 39, and a rotating plate gear 44 is arranged on the output shaft of the rotating plate motor 43. The rotating plate gear 44 and the rotating plate 40 form a gear pair. An axial control electric cylinder 41 is fixedly arranged on the rotating plate 40, and a telescopic rod 42 is fixedly arranged on the telescopic rod of the axial control electric cylinder 41. A hole is opened, and the telescopic rod 45 is located in the hole. The pressure-sensitive detector between the telescopic rod 45 and the telescopic rod 1 42 is composed of a pressure-sensitive sensor and a pressure spring 4502. The telescopic rod 45 moves to the spring wire diameter. When the rotating plate 40 rotates, the end of the telescopic rod 45 moves on the spring wire diameter, and the pressure spring 4502 is compressed. The pressure-sensitive sensor outputs a pressure signal to the analysis system to detect the rotation direction of the spring. A pressure-sensitive detection part 4501 is arranged on the circumference of one end of the telescopic rod 45. When the rotating plate 40 rotates, the pressure-sensitive detection part 4501 contacts the end of the spring wire diameter. The pressure-sensitive detection part 4501 outputs the pressure information to the analysis system to detect the rotation direction of the spring.

[0027] The principle of implementing the present invention is as follows: the spring is placed inside the positioning tube 5, that is, between the fixing rods 25, and is supported and fixed by the fixing rods 25. Specifically, the fixing motor 20 works and controls the push ring 23 to rotate under the gear transmission. The push wheel 24 pushes the inclined portion on the slide bar 26, so that the slide bar 26 and the fixing rod 25 move radially, and the connecting spring 27 is compressed; further, the spring is positioned and fixed (the operator does not need to perform precise positioning when installing the spring, and the spring can be subjected to subsequent calibration and detection operations to complete the determination of the cutting position).

[0028] First, determine the spring cutting position. Specifically, the motor 7 works, the screw 8 rotates, and the slide 10 slides, so that the position push plate 37 on the detection seat 35 corresponds to the position of the spring end. The motor 29 works, and the belt structure on the output shaft of the motor 29 drives the screw 2 11 to rotate (the electromagnetic clamp seat 34 on the inner side of the pulley on the belt structure clamps and fixes the corresponding end of the screw 2 11 to rotate synchronously); the detection seat 35 is moved to the preset position at the end of the rotating drum 16, and the axial motor 19 works, and the axial screw The rod 18 rotates, and then the axial slip ring 22 moves, so that the fixed rod 25 clamps the spring and moves. The wire diameter end of the spring first contacts the position push plate 37 and pushes the position push plate 37. The pressure-sensitive detector between the position push plate 37 and the end face of the detection seat 1 35 outputs a feedback pressure signal, thereby determining the spring cutting position; then the spring rotation direction is further determined. Specifically, the detection seat 2 36 moves and corresponds to the end position of the spring. By controlling the rotation of the screw rod 2 11, the detection seat 2 36 moves toward the end position of the spring to a preset position, and the axial control The electric cylinder 41 works to move the telescopic rod 1 42 and the telescopic rod 2 45 and make the end of the telescopic rod 2 45 contact the surface of the spring wire diameter. At this time, since the rotation direction of the spring is unknown, the rotating plate motor 43 works. Under the gear transmission, the rotating plate 40 rotates, and the end of the telescopic rod 2 45 moves on the spring wire diameter. In the first case, when the telescopic rod 2 45 moves on the spring wire diameter, the telescopic rod 2 45 will move axially under the push of the spring wire diameter, and then the pressure-sensitive detector between the telescopic rod 2 45 and the telescopic rod 1 42 outputs a feedback pressure signal. When the end of the telescopic rod 45 meets the end of the spring wire diameter, the telescopic rod 45 jumps and moves, that is, it separates from the end of the spring wire diameter, and the pressure-sensitive detector between the telescopic rod 45 and the telescopic rod 1 42 outputs a feedback jump signal, thereby determining the rotation direction of the spring; the second situation: the rotating plate 40 rotates, the telescopic rod 45 rotates, and the pressure-sensitive detection part 4501 at the end contacts the end of the spring wire diameter, and then the pressure-sensitive detection part 4501 outputs a feedback pressure signal, thereby determining the rotation direction of the spring; in both cases, the rotation direction of the spring is opposite.

[0029] After the spring rotation direction and cutting position are determined, the rotating motor 14 is operated, and the rotating drum 16 is rotated under the gear transmission, and then the angle of the spring wire diameter end is adjusted, that is, the spring wire diameter end is adjusted to the corresponding position of the cutting piece, so that the initial point of cutting is at the spring wire diameter end, which is conducive to the continuity of cutting (cutting from the end until the cutting is completed, making the cutting surface smoother, if not cutting from the end, that is, cutting from the circumference of the wire diameter, the cut waste will not be continuous, and the flatness of the cutting surface is poor); when cutting, the lifting motor 28 is operated to move the lifting screw 29 and the lifting guide rod 30, so that the cutting wheel 33 is located at the cutting position, and the cutting motor 32 is operated to perform the cutting work, and further, the spring is rotated by the rotating motor 14, and the cutting wheel 33 is cut along the spring wire diameter; after completing the cutting of one end, the reversing motor 2 is operated to rotate the rotating shaft 4 and the positioning drum 5 to complete the reversal of the spring end and perform the cutting of the other end face. The cutting position and rotation direction can be determined through the above process.
