At present, in the construction process of high-voltage cable joints, the high-voltage cable cutting and stripping process is a key process that is time-consuming and labor-intensive and has very high process requirements. It is highly dependent on manual labor. This process requires cutting and stripping the outer semi-conductive layer of the cable as required, cutting off a certain length of the outer semi-conductive layer and exposing the insulating layer, cutting and stripping a certain length of the outer semi-conductive layer slope at an appropriate position, and then grinding the outer surface to make the cable insulation layer surface, the semi-conductive layer slope and the transition area between the two smooth and round.

[0046] like Figure 7 As shown, a third motor 14 is fixedly mounted on the outer surface of one side of the turntable 16, and the third motor 14 is fixedly connected to a connecting plate 38.

[0054] Preferably, the number of the spline shafts 7 may be two to six.

[0055] The present invention also provides a method for using the automatic cutting and stripping device for high-voltage cable insulation layer, comprising the following steps:

[0056] Step 1: Pass the high-voltage cable 5 to be cut and stripped through the first through holes 3 at both ends, rotate the first micro screw mechanism 21 on the clamping mechanism 4 to move the second clamping claw 192 downward, clamp and fix the high-voltage cable 5 to be cut and stripped, and adjust the height of the high-voltage cable 5;

[0057] Step 2: Start the first motor 8 to drive the first screw mechanism 6 to rotate, and the nut 10 drives the translation mechanism 9 to move in the horizontal direction through the forward and reverse rotation of the first screw mechanism 6;

[0059] Step 4: Start the third motor 14, which drives the second screw mechanism 40 to rotate, controls the sliding block 41 on the second screw mechanism 40 to move along the direction of the connecting groove 39, adjusts the depth of the tip of the tool 15 inserted into the high-voltage cable 5, and then controls the depth of cutting the outer surface of the high-voltage cable 5.

[0060] Step 5: The first motor 8 , the second motor 36 and the third motor 14 move simultaneously so that the cutter 15 cuts a spiral cut on the outer surface of the high-voltage cable 5 ;

[0061] Step 6: The worker peels off the cut outer surface of the high-voltage cable 5 through a spiral incision.

[0062] The beneficial effect of the present invention is that, compared with the prior art, the present invention can rotate the first micro screw mechanism to move the second clamping claw on the upper side downward to clamp and fix the high-voltage cable to be cut and stripped, so that the high-voltage cable can be fine-tuned in the height direction and the high-voltage cable to be cut and stripped can be fixed stably.
