An arc plate 24 is fixedly provided, and the arc plate 24 is located on the outside of the arc plate 13 and is arranged cocentrically with the arc plate 13. A pressing seat 10 is fixedly provided on one side of the inner wall of the bottom of the frame 1, and a pressing block 11 is provided on the other side of the inner wall of the bottom of the frame 1. A hydraulic cylinder 12 is fixedly provided on the outside of the bottom of the frame 1, and the push rod of the hydraulic cylinder 12 is fixedly connected to the back side of the pressing block 11. The outer wall of the bottom of the wire stripping drum 2 is integrally formed with a ring tooth 6, and a gear 7 is coaxially fixedly provided on the motor shaft of the driving motor 8, and the gear 7 is meshed with the ring tooth 6.
[0018] In a specific embodiment of the present invention, the electric energy of the electric push rod 5 is provided by a direct connection between a wire and a power supply, and the push rod telescopic distance of the electric push rod 5 is precisely controlled by a controller A (not shown in the figure). The two arc plates 2 4 are wrapped around the outside of the four arc plates 1 3. The tool head of the wire stripping tool 301 is located on the inner side of the wire stripping barrel 2. The rod body of the wire stripping tool 301 is a square column, and the square column part is provided with a groove body for clamping the clamp 1 302 and the clamp 2 304. The clamp 2 304 cooperates with the spring 303 to enable the wire stripping tool 301 to have an elastic reset function. When the arc plates 2 4 synchronously press the arc plates 1 3, the four wire stripping tools 301 synchronously move toward the center of the wire stripping barrel 2. When the arc plates 2 4 synchronously move away from the arc plates 1 3, the four wire stripping tools 301 synchronously move toward the direction away from the center of the wire stripping barrel 2, thereby achieving The electric push rod 5 now regulates the stripping depth of the four stripping tools 301. The electric energy of the drive motor 8 is provided by a direct connection between the wire and the power supply. The start and stop of the drive motor 8 is precisely controlled by the controller B (not shown in the figure). A retreat hole horizontally aligned with the gear 7 is opened on one side of the frame 1 to provide space for the normal rotation of the gear 7. When the gear 7 rotates, it can drive the stripping drum 2 to rotate. The discharge hole 13 is used to discharge the stripped insulation layer. The press-fit joint can be placed between the press-fit seat 10 and the press-fit block 11, and then the end of the cable with the insulation layer stripped is inserted into the press-fit joint. The push rod of the hydraulic cylinder 12 is controlled to extend (the hydraulic cylinder 12 is provided with a hydraulic source and control by a hydraulic component, and the hydraulic component protects the hydraulic pump, solenoid valve, pipeline and oil tank combination), so that the press-fit block 11 cooperates with the press-fit seat to press the press-fit joint with the conductive end of the cable.
[0019] In the preferred technical solution, the wire stripping tool 301 is inlaid with a clamp 1 302 and a clamp 2 304. The clamp 1 302 is located on the inner side of the wire stripping barrel 2, and the clamp 2 304 is located on the outer side of the wire stripping barrel 2. The wire stripping tool 301 is inlaid with a spring 303 on the outside, and the spring 303 is located between the wire stripping barrel 2 and the clamp 2 304. The clamp 2 304 cooperates with the spring 303 to enable the wire stripping tool 301 to have the function of elastic reset, and the clamp 1 302 can prevent the wire stripping tool 301 from being easily separated from the wire stripping barrel 2.
[0020] In the preferred technical solution, the pressing seat 10 has a V-shaped shape, and the pressing block 11 has a triangular shape. The V-shaped angle of the pressing seat 10 is consistent with the triangular vertex angle of the pressing block 11. The pressing joint is placed between the pressing seat 10 and the pressing block 11, and then the end of the cable with the insulation layer stripped off is inserted into the pressing joint. The push rod of the hydraulic cylinder 12 is controlled to extend, so that the pressing block 11 cooperates with the pressing seat to press the pressing joint with the conductive end of the cable.
[0021] In the preferred technical solution, a discharge hole 13 is provided at the bottom center of the frame 1 and is vertically aligned with the wire stripping drum 2. The diameter of the discharge hole 13 is consistent with the inner diameter of the wire stripping drum 2. The cut-off part of the cable insulation layer is separated from the cable, and the separated cable insulation layer leaks out through the inside of the wire stripping drum 2 and is finally discharged from the discharge hole 13.
[0022] Working principle: by putting the cable end into the stripping drum 2, the push rod of the electric push rod 5 extends, so that the arc plate 2 4 presses the arc plate 1 3 synchronously, and the four stripping knives 301 move synchronously toward the center of the stripping drum 2 until the stripping knives 301 are inserted into the cable insulation layer, and then the driving motor 8 is started, and the gear 7 can drive the stripping drum 2 to rotate when it rotates. At this time, the four stripping knives 301 rotate synchronously around the outside of the cable, thereby cutting off the cable insulation layer, and then the cable is pulled back to separate the cut-off part of the cable insulation layer from the cable, and the cable is separated. The separated cable insulation layer leaks out through the inside of the stripping barrel 2 and is finally discharged from the discharge hole 13. Then, the push rod of the electric push rod 5 is controlled to retract and reset. The resilience of the spring 303 makes the four stripping tools 301 move synchronously in the direction away from the center of the stripping barrel 2, and the cable continues to move downward, and the pressing joint is placed between the pressing seat 10 and the pressing block 11. Then, the end of the cable with the insulation layer stripped off is inserted into the pressing joint, and the push rod of the hydraulic cylinder 12 is controlled to extend, so that the pressing block 11 cooperates with the pressing seat to press the pressing joint with the conductive end of the cable.
