Electric internal rotation type electric cable making tool

Abstract

The invention relates to the field of electric cable end making and specifically relates to an electric internal rotation type electric cable making tool comprising an electric drill, a connecting rod, a sleeve cylinder, a cutting tool, polishing sand paper and a fixing member, wherein one end of the connecting rod is connected with the electric drill while the other end is connected with the sleeve cylinder, the fixing member is arranged on the sleeve cylinder, and the cutting tool and the polishing sand paper are fixed in the sleeve cylinder via the fixing member. An power-driven mode is adopted for supplying power for the electric internal rotation type electric cable making tool provided in the invention; high speed and labor saving and time saving performance can be realized; the cutting tool and the sand paper can be adjusted to adapt to electrical cables of different specifications, and strong applicability can be realized; tightness of the built-in sand paper can be adjusted, the sand paper can closely cling to an electric cable insulation layer, a working surface is enabled to be under uniform stress, and phenomena of non-uniform polishing can be overcome; the tool can be operated by an operator when the tool is arranged on the electric cables in a sleeving manner and a power-on button is pressed, and the tool is easy and convenient to use; if the tool is operated by an unversed person, work pieces can be enabled to finally meet technological requirements via a polishing procedure.

Problems solved by technology

[0002] At present, in the process of making 10 kV and 35 kV cable heads on site, the construction technology requirements are very high, and cables with low manufacturing technology often have breakdown failures, so the semi-conductive layer of the cable needs to be stripped during production. Removal and polishing of the insulating layer to ensure that the cable production meets the requirements of the production process; in the prior art: when the manufacturer produces cable accessories, some tools will be attached to the cable terminal accessories, and the construction personnel use these accessory tools to carry out Cable production; or use a blade to manually peel and cut the outer semiconducting layer. Because the semiconducting layer is very thin, it is required to cut two-thirds or three-quarters of the thickness of the outer semiconducting layer. It is difficult to grasp the strength of the hand, so it is easy To destroy the insulating layer under the semiconducting layer, there are also some tools for stripping and cutting the semiconducting layer, such as a stripping tool with multiple blades in a round tube. Since the round tube and the cable may not be completely concentric during installation and adjustment, the stripping depth of each blade Inconsistent, the depth of the knife mark does not meet the design requirements, the electric field of the cable head is uneven after stripping, and the produced cable head is easy to discharge and burn out, so the stripping effect is not very ideal. It is inconvenient to get up, time-consuming and labor-intensive

When the construction personnel peel off the semiconductive layer and process the insulating layer, there will be construction quality problems such as the semiconductive layer is not stripped smoothly, there are too many burrs, and the insulating layer is cut by a knife. In the end, the life of the cable is too short or even fails, and a large amount of economic losses
