The invention belongs to the technical field of
power cable installation, operation and maintenance, and discloses a cable main insulation reducing part
conical surface machining device and a using method thereof.The device comprises a cable fixing component, an adjustable guide mechanism, an adjustable tool rest component and a driving component; the cable fixing part comprises a main
body frame and clamping mechanisms, the multiple clamping mechanisms are arranged in the circumferential direction of the main
body frame, and the adjustable guide mechanism is connected with the main
body frame; the adjustable tool rest part comprises a tool rest main body, a guide
assembly, a tool and a feeding control structure, the tool rest main body is in sliding connection with the adjustable guide mechanism through the guide
assembly, and the tool rest main body axially moves and circumferentially rotates along the adjustable guide mechanism at the same time to drive the tool to
cut the
diameter-variable part of the main insulation of the cable; the feeding control structure controls the radial
cutting depth of the cutter; the driving part is connected with the tool rest body. The angle and the length of the
conical surface of the
cut cable main insulation can be controlled, quantitative adjustment of the
cutting depth is achieved, the
machining error is small, and the cable main insulation installation
process quality is guaranteed.
