Embodiment Construction
[0019] figure 1 1-6 represent the six layers of high-voltage cables. L1 is the length of the first section to be removed, L2 is the length of the second section to be removed, L3 is the length of the third section to be removed, L4 is the length of the fourth section to be removed, L5 is the length of the fifth section to be removed, L6 is the sixth length to be resected. In order to complete the layered cutting of the above six sections, at present, a tape measure is used to measure one section, and one section is cut off. The present invention can complete the scribing of the above-mentioned multi-layer cutting positions at one time.
[0020] A high-voltage cable head scribing cutting positioning method, the right end face of the main ruler claw end positioning block of the high-voltage cable head scribing and cutting positioner is facing it with the end of the high-voltage cable to be cut, and the auxiliary ruler snap ring is clamped on the high-voltage cable On the outer...

Abstract
The invention discloses a line-scribing, cutting, and positioning method of a high-voltage cable head. The right end surface of a main scale jaw end positioning block of a line-scribing cutting positioner of the high-voltage cable head and the end surface of a to-be-cut high-voltage cable are aligned, an auxiliary scale clamping ring is clamped at the excircle of the high-voltage cable, an auxiliary scale is moved to a required line-scribing dimension L1, a first line-scribing, cutting, and positioning auxiliary device is installed, the right end surface of the auxiliary device is aligned with the left end surface of the auxiliary scale, a screw is locked, and the position of the line-scribing position L1 is determined; the positions of the line-scribing positions L2, L3, L4, L5,..., and Ln are determined via the above repeated operation; and finally, the line scribing of the excircle of the high-voltage cable is performed in sequence by employing a line-scribing tool, the corresponding positions from dimensions L1 to Ln are determined, and materials in need of being stripped are cut and stripped layer by layer. According to the method, one-time line-scribing positioning can be realized, the precision reaches 0.02 mm, and an outer sheath, a steel band armor, a copper shielding layer, a semiconducting layer, and a cable major insulation layer etc. of the cable are stripped in a layered manner according to the line-scribing positions.
Description
[0001] This application is a divisional application with the application number: 201310297253.5, the application date: 2013.7.16, and the name "High Voltage Cable Head Scribing, Cutting and Positioning Method". technical field [0002] The invention relates to a method for scribing, cutting and positioning a high-voltage cable head. Background technique [0003] The high-voltage cable head is peeled off in layers such as the cable sheath, steel tape armor, copper shielding layer, semi-conductive layer, and cable main insulation layer. The stripped size must be accurate to the millimeter level, or even higher. In the cable terminal assembly, the crimping part of the outlet terminal, the cover cap, the terminal insulation body, the insulation tube, the winding part of the self-adhesive tape of the semi-conductive layer, the fixing of the constant force spring hoop, the fixing of the copper braid, and the three sets of sleeves are accurate according to different positions. When...
