[0029] A limiting groove 5 is provided on the upper side of the fixing seat 4, and two symmetrically arranged limiting plates 20 are installed on the upper side of the fixing seat 4. By installing and using the limiting groove 5 and the limiting plate 20, the two can be used to limit the power cable, making the wire stripping work more stable. The upper side of the U-shaped top plate 2 is fixedly connected to two symmetrically arranged support plates 6, and the inner sides of the two support plates 6 are rotatably connected to the first wire wheel 7.

[0030] The lower side of the U-shaped top plate 2 is connected to two symmetrically arranged connecting plates 25, the inner side surfaces of the two connecting plates 25 are rotatably connected to the double-headed screw rod 26, and the outer surface of the double-headed screw rod 26 is threadedly connected to two symmetrically arranged displacement plates 29, one side of the two displacement plates 29 is slidably connected to a U-shaped movable seat 30, and the inner sides of the two U-shaped movable seats 30 are rotatably connected to the second wire wheels 32 distributed in an array.

The rear side of the double-headed screw rod 26 passes through the connecting plate 25 and extends to the rear side of the connecting plate 25. The rear side of the double-headed screw rod 26 is fixedly installed with a No. 3 servo motor 27 through a motor mounting plate. The inner side surfaces of the two connecting plates 25 are connected to two second smooth rods 28. Through the setting of the second smooth rods 28, the two displacement plates 29 can be restricted by the two second smooth rods 28, so that the two sets of second wire wheels 32 can be moved toward each other smoothly, so as to limit the transmission of cables for wire stripping. The outer surfaces of the two second smooth rods 28 are slidably connected to the interior of the displacement plate 29.

[0032] Two symmetrically arranged fixed plates 21 are installed on the upper side of the cable stripping device base 1.

[0033] The upper side of the threaded rotating rod 10 passes through the U-shaped plate 9 and extends to the upper side of the U-shaped plate 9. The upper side of the threaded rotating rod 10 is fixedly connected to the No. 1 servo motor 18 through the motor mounting plate. The inner side of the positioning plug-in plate 15 passes through the mounting seat 12 and extends to the inside of the knife seat 13. The fixed seat 4 is located directly below the wire stripping cutter 14. Two first smooth rods 19 are connected to the inside of the U-shaped plate 9. Through the setting of the first smooth rods 19, the two first smooth rods 19 can limit the trajectory of the lifting plate 11, so that the lifting plate 11 drives the wire stripping cutter 14 to move up and down smoothly, which is used to adjust the height of the wire stripping cutter 14. The outer surfaces of the two first smooth rods 19 are slidably connected to the inside of the lifting plate 11.

[0034] Positioning slots 100 are provided on both sides of the mounting seat 12 . The positioning slots 100 are adapted to the telescopic stopper 16 . One side of the telescopic stopper 16 is engaged with both sides of the mounting seat 12 through the positioning slots 100 .

[0035] The working principle of the power cable stripping device provided by the utility model is as follows:

[0036] By pressing the two telescopic stops 16 equipped with the first spring 17 on the knife seat 13, the two telescopic stops 16 can be stored in the inside of the knife seat 13, and then the knife seat 13 is clamped to the bottom of the mounting seat 12. At this time, the two telescopic stops 16 are automatically extended due to the elastic force of the first spring 17, so as to be clamped and fixed to the positioning slots 100 of the mounting seat 12, which is used for preliminary positioning of the wire stripping cutter 14 at the knife seat 13. Then, the two positioning plug plates 15 are inserted into the mounting seat 12 and the knife seat 13 in turn to further lock the wire stripping cutter 14, so that the wire stripping cutter 14 can be stably and reliably fixed. In this way, the wire stripping cutter 14 can be quickly replaced by clamping, and there is no need to use the screw installation method, which saves time and effort in replacement. At the same time, it can also avoid the problem of screw slippage, thereby improving the stripping effect of the power cable stripping device;

[0037] By allowing the output shaft of the No. 3 servo motor 27 to drive the double-headed screw 26 to rotate, the two displacement plates 29 on the double-headed screw 26 can move toward each other, so that the two U-shaped movable seats 30 equipped with the second spring 31 can shorten the spacing to adapt to cables of different sizes. At this time, the second wire pulleys 32 at the two U-shaped movable seats 30 can guide the movement of the cables, allowing the stripping work to proceed stably. Subsequently, the cables to be stripped are sequentially passed through the first wire pulley 7, the second wire pulley 32, the fixed seat 4, and the L-shaped card plate 23 of the winding roller 22. Then, the output group of the No. 1 servo motor 18 drives the threaded rotating rod 10 to drive the lifting plate 11 on the threaded rotating rod 10 to drive the wire stripping cutter 14 to move downward and fit above the cable to be stripped. Then, the No. 2 servo motor 24 is started, and the output shaft of the No. 2 servo motor 24 drives the winding roller 22 to rotate. In this way, the winding roller 22 can drive the cable to move, allowing the wire stripping cutter 14 to cut and strip the cable continuously. At the same time, the winding roller 22 is also used to wind up the separated insulation layer of the cable, exposing the copper core of the power cable.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
