[0069] like Figure 3 , Figure 4 As shown, the tool radial control mechanism 1 includes a motor 105, the output end of the motor 105 is connected to the transmission screw 103 through a coupling, and a plate body 109 is also fixed to the motor 105. A track fixing sleeve 107 and a pair of guide sleeves 104 are respectively installed on the plate body 109. The track fixing sleeve 107 cooperates with one end of the track fixing rod 102, and the other end of the track fixing rod 102 is connected to the fixing seat matching groove 2065 of the tool rail assembly through the tool rail assembly connecting sleeve 101.

[0071] like Fig.15 , Fig.16 As shown, the specific structure of the tool axial control mechanism 6 is as follows: it includes a second stepper motor 601, the second stepper motor 601 is fixed on the second stepper motor mounting seat 602, the output end of the second stepper motor 601 is connected to the second ball screw 603 through a coupling, the second screw nut 608 is screwed to the second ball screw 603, the second screw nut 608 is fixed to the second movable plate 604, the second movable plate 604 is connected to the third movable plate 606 through a connecting plate 605 and a pair of connecting columns 609, wherein the outer ring of one connecting column 609 is matched with the rotating motor fixing plate 215.

[0072] The method for stripping wires using the automatic wire stripping machine comprises the following steps:

[0073] A: Input the cable wave cutting data into the control terminal and start the automatic wire stripping machine.

[0074] B: The locking mechanism 3 starts and locks the cable. Fig.17 , Fig.18 and Fig.19As shown, the first stepper motor 301 is started and drives the first ball screw 3031 to rotate through the coupling. Since the first ball screw 3031 is connected to the first movable plate 305 through the first screw nut 3032, and the front end of the first movable plate 305 is fixedly connected to the wedge block slide rod 307, the wedge block slide rod 307 moves axially and drives the wedge block 308 connected thereto to move, as shown in FIG. Fig.17 , Fig.18 As shown in FIG. 1 , since the rotating wheel fixing block 310 is installed on the fixing plate 4, and the bottom of the rotating wheel fixing block 310 contacts the wedge surface of the wedge block 308 through the locking rotating wheel 309, the rotating wheel fixing block 310 opens to both sides when the wedge surface gradually increases, so that the rotating wheel fixing block 310 drives the locking shaft 312 to rotate when it rotates to open, as shown in FIG. Fig.19 As shown, the locking shaft 312 rotates and drives the locking push rod 315 to rotate outward, and the other end of the locking push rod 315 rotates inward and drives each V-block fixed slider 318 to approach through the locking cam 317, and the cable is placed in the groove of the V-block 319. Each V-block 319 is staggered, so it gradually cooperates and locks the cable during the approach process.

[0075] C: The tool axial control mechanism 6 starts and drives the rotary cutting mechanism 2 and the tool radial control mechanism 1 to move to the stripping position. Fig.15 , Fig.16 As shown, the second stepper motor 601 is started, and the output end of the second stepper motor 601 drives the second ball screw 603 to rotate through the coupling, and the second screw nut 608 moves axially along the second ball screw 603 and drives the second movable plate 604 to move. The second movable plate 604 not only cooperates with the rotating shaft 208 through the fixed bearing seat 210 and the rotating shaft bearing 209, but also connects to the third movable plate 606 through the connecting column 609, and the connecting column 609 also cooperates with the rotating motor fixing plate 215 of the fixed rotating motor 214. The above-mentioned second movable plate 604 is also connected to the transmission screw 103 through the screw seat 110. Therefore, the second movable plate 604 moves axially to drive the rotating cutting mechanism 2 and the tool radial control mechanism 1 to feed axially to the stripping position.

[0076] D: If Figure 6 , Figure 7 , Figure 8 , Figures 10 to 14 As shown, the rotating unit of the rotary cutting mechanism 2 is started, the rotating motor 214 is started and the power is transmitted to the motor gear 211 through the connecting shaft 213, the motor gear 211 engages the rotating shaft gear 212 and realizes the rotation of the rotating shaft 208, and the tool rail fixing member 204, the blade mounting seat 202 and the blade 201 are driven to rotate through the rotating shaft 208 (the blade has not yet made radial movement during this process). Figure 3 , Fig.16As shown, the motor 105 of the tool radial control mechanism 1 is started, and the motor 105 starts to drive the transmission screw 103 to rotate. Since the transmission screw 103 is threadedly connected with the screw seat 110, and the screw seat 110 is fixed on the second movable plate 604, the transmission screw 103 moves forward and backward relative to the screw seat 110. While the transmission screw 103 moves forward and backward, it drives the motor 105 and the plate body 109 fixed to the motor 105 to move axially. The movement of the plate body 109 drives the guide sleeve 104 and the track fixing sleeve 107 to follow, as shown in FIG. Figure 1 As shown, the guide sleeve 104 moves along the first guide rod 108. Figure 3 As shown, the track fixing sleeve 107 drives the track fixing rod 102 and the tool rail assembly connecting sleeve 101 to move axially, as shown in FIG. Figure 3 , Figure 4 and Figure 5 As shown, since the tool rail assembly connecting sleeve 101 is fixed to the outer tool rail 2061 and the inner tool rail 2062 of the tool rail assembly through the fastener and the lock hole 2067, and as shown in FIG. Figure 4 As shown, the tool rail assembly connecting sleeve 101 is located in the rotating shaft 208, and the tool rail assembly connecting sleeve 101 extends from the through slot 2081 of the rotating shaft 208 and cooperates with the fixing seat matching slot 2065, so that the tool rail assembly (external tool rail 2061, internal tool rail 2062) can move synchronously.

[0077] The movement of the tool rail assembly relative to the tool rail fixing member 204 will drive the cam 207 to slide along the track formed by the cam slide groove 2063, thereby driving the tool rod 203 to produce radial displacement. The tool rod 203 is connected to the tool rail fixing member 204 by rotating the support rod 205, so that the other side of the tool rod 203 produces a reverse radial movement opposite to the above-mentioned radial displacement. Fig. 9 As shown, the reverse radial movement causes the cutter bar 203 and the second blade feed slot 2031 to move, thereby driving the blade protruding end 2011 of the blade 201 to move in the direction of the arrow along the first blade feed slot 2022, thereby realizing radial feeding of the blade 201, so that the cutting diameter of the tool changes from Φ60 to Φ52, and then repeating step C so that the tool axial control mechanism 6 controls the rotating blade 201 that is radially fed to the appropriate position to continuously axially cut the rubber part of the cable.

[0078] E: The tool radial control mechanism 1 controls the tool to cut to the required depth, specifically by repeating step D to change the tool cutting diameter from Φ52 to Φ50, thereby achieving the required depth.

[0079] F: The tool axial control mechanism 6 controls the tool to feed axially to the next stripping position at a diameter of Φ50. The specific feeding steps are the same as step C.

[0080] G: The rotary cutting mechanism 2 stops, and the tool axial control mechanism 6 controls the tool to retract to the initial position;

[0081] H: The locking mechanism 3 is activated and the cable is released, and then steps AH are repeated to continue the cable stripping work. The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. The present invention can be modified in any form without violating the basic structure of the present invention.
