Tapping and positioning mould of heat-shrinkage casing pipe on surface of copper bar

Abstract

The invention discloses a tapping and positioning mould of a heat-shrinkage casing pipe on the surface of a copper bar, and belongs to the technical field of high-voltage power transmission and distribution equipment. The tapping and positioning mould of the heat-shrinkage casing pipe on the surface of the copper bar comprises a cutter rest and a main shaft fixing frame with a cutter rest guide rail; the cutter rest is installed on the cutter rest guide rail and can move left and right along the cutter rest guide rail; the lower end of the main shaft fixing frame is provided with a detachable hole positioning shaft; and the lower end of the cutter rest is provided with a detachable cutter blade. After the structure is adopted, because of the arranged main shaft fixed frame and hole positioning shaft, positioning is carried out when tapping is required; then the tapping is carried out by the cutter blade on the cutter rest, the positioning is accurate, and a notch is beautiful; and meanwhile, because the hole positioning shaft and the cutter rest can be adjusted, holes with different sizes can be tapped, the tapping requirement of various diameters can be met; and with the device, the positioning is accurate, and the cutting speed is high, thus tapped holes are standard and beautiful, meanwhile, the working efficiency is also improved, and the production cost is lowered.

Description

[0001] technical field [0002] The invention relates to a tool for opening and positioning heat shrinkable sleeves on the surface of copper bars used in high-voltage switches, and belongs to the technical field of high-voltage power transmission and distribution equipment. Background technique [0003] At present, in high-voltage power transmission and distribution equipment, heat-shrinkable sleeves are often installed on the surface of copper bars for insulation. The hole opening operations are all cut directly on site with a utility knife. Although this method can be used to open the heat shrinkable sleeve on the surface of the copper bar, due to the large randomness of the manual operation, the shape and size of the openings of different operators are very different, and the artificially cut holes are very difficult. Irregularity affects the appearance. At the same time, due to the difficulty of accurate positioning of manual opening, the efficiency of opening is relati...

Although this method can be used to open the heat shrinkable sleeve on the surface of the copper bar, due to the large randomness of the manual operation, the shape and size of the openings of different operators are very different, and the artificially cut holes are very difficult. Irregularity affects the appearance. At the same time, because the manual opening is difficult to locate accurately, the opening efficiency is relatively low, which wastes working time and wastes production costs.
