Full Diameter Composite Core Conductor Rotary Cutting Fixture

Abstract

The invention relates to a full-diameter composite core wire rotary cutting fixture, which includes a wire clamping assembly and a cutting machine mounting bracket, and the wire clamping assembly includes a first barrel body, a second barrel body and a clamping screw The column, the first cylinder unit and the second cylinder unit are combined to form a complete, cylindrical support cylinder, and the two butt joints of the first cylinder unit and the second cylinder unit are respectively connected by hinges and buckles A movable opening and closing structure is formed. At least two groups of clamping studs are arranged on the supporting cylinder. The clamping studs are arranged along the radial direction of the supporting cylinder and connected by threads. The cutting machine mounting bracket includes a rotating fixed body, Positioning ring, main frame body and sub-frame body; the invention can realize the cutting of the cored wire in the full diameter range, and the cutting machine is manually rotated to cut the wire, and the precise and non-damaging cutting of the cored wire is realized. The invention can be used in ground and high-altitude operations, and can greatly improve construction efficiency and construction accuracy.

Description

technical field [0001] The invention relates to the technical field of wire butt joint tools, in particular to a full-diameter composite core wire rotary cutting fixture. Background technique [0002] At present, the high-voltage wires are all made of steel core or carbon fiber composite core wire, and several layers of aluminum stranded wire are wrapped on the outside. Before the wire is crimped, the outer layer of aluminum stranded wire needs to be stripped to cut off the aluminum strands to expose the steel core or The carbon fiber composite core wire is used for connection. The quality of the wire connection is the key link to ensure the smooth flow of the wire line.

[0002] At present, the high-voltage wires are all made of steel core or carbon fiber composite core wire, and several layers of aluminum stranded wire are wrapped on the outside. Before the wire is crimped, the outer layer of aluminum stranded wire needs to be stripped to cut off the aluminum strands to expose the steel core or The carbon fiber composite core wire is used for connection. The quality of the wire connection is the key link to ensure the smooth flow of the wire line. However, in such a critical construction link, it is completely manually operated by the construction personnel. The tools used are ordinary utility knives, hand saws, Vise, file, tape measure and sandpaper, the most commonly used auxiliary tools are manual hydraulic pliers that are only used when crimping metal wire joints or casings. Electric hydraulic pliers are considered high-end tools. Due to the complicated manufacturing process, It is not easy for construction workers to be proficient, and construction defects often appear. Most of the power failures are caused by such reasons. In order to reduce construction defects, some simple manual tools are gradually used in the industry by referring to foreign methods, such as wire cutters and small electric belts. Saws, manual strippers, electro-hydraulic pliers, etc., only slightly reduce the amount of labor. For the key quality factors of wire pretreatment, such as the cutting depth and position accuracy control of the wire sheath, the shielding layer and semiconducting layer of the split-phase wire , the peeling depth and position accuracy of the insulating layer, the shape of the cutting section and the surface quality, etc., there is almost no improvement. Therefore, a new type of wire cutting equipment is urgently needed to change the existing situation
