Description

Cable stripping tool

technical field

The invention relates to a stripping tool for cables in the field of transmission line construction.

Background technique

With the development and promotion of electric power, the use of cables is becoming more and more extensive. Basically, cables are used in all walks of life. During the use of cables, it is inevitable to cut and strip the cables. For example, the cables in power transmission cables usually use steel-cored aluminum stranded wires, which include the central steel core and the multi-layer aluminum stranded wires arranged on the periphery of the steel core. When the cables are connected, they need to be disconnected first, and then Strip off the aluminum stranded wires around the steel core, and finally crimp the steel cores of the two cables.

Existing wire stripping tools such as "a kind of wire stripping tool" disclosed in China CN107147050A include a cutting mechanism and a knife body driving mechanism, and the cutting mechanism includes a mechanism seat, and the mechanism seat is provided with two relatively movable and oppositely movable Knife bodies, at least one of which is a moving knife body connected to the drive mechanism of the knife body. A wire core avoidance groove is provided on the blades of the two knife bodies to avoid damage to the steel core in the middle of the cable. The mechanism seat also guides The mobile device is equipped with a cable positioning sleeve, and the guiding movement direction of the cable positioning sleeve is consistent with the moving direction of the moving knife body. The cable positioning sleeve is usually separated from the mechanism seat, and the cable positioning sleeve and the mechanism seat are only guided together when in use. . When in use, first put the cable to be stripped through the cable positioning sleeve, and then the operator guides and connects the cable positioning sleeve with the mechanism seat. The cable positioning sleeve is used to locate the positional relationship between the cable and the core avoidance groove , to ensure that the steel core is just in the wire core avoidance groove, so as to avoid the steel core being accidentally damaged by the knife body. The problem with the existing stripping tool is that the cable positioning sleeve is a positioning part, and its purpose is to locate the relationship between the steel core and the wire core avoidance groove. However, in the prior art, the cable positioning sleeve guides and moves Mechanism seat, so there must be wear and tear between the cable positioning sleeve and the mechanism seat, after wear, it will affect the positioning relationship of the cable positioning sleeve to the cable.

Contents of the invention

The purpose of the present invention is to provide a cable stripping tool to solve the problem in the prior art that the wear between the cable positioning sleeve and the mechanism seat will affect the positioning of the cable by the cable positioning sleeve.

In order to solve the problems of the technologies described above, the technical solution of the present invention is as follows:

A wire stripping tool for cables, including a cutting mechanism and a knife body driving mechanism, the cutting mechanism includes a mechanism seat, a cable positioning sleeve is fixedly arranged on the mechanism seat for wearing a corresponding cable, and a guiding and moving device is installed on the mechanism seat Two moving knife bodies that are driven by the driving mechanism of the knife body and can move relative to each other. The two moving knife bodies are distributed on both sides of the cable positioning sleeve, and the opposite sides of the two moving knife bodies are provided with wire core avoidance grooves. , the axis of the cable positioning sleeve is in the extension direction of the movement track of the core escape groove.

The mechanism base includes two guide rods arranged side by side, and each movable knife body is guided to move and assembled on the two guide rods, and the cable positioning sleeve is fixed at the middle of the two guide rods.

The cable positioning sleeve includes a fixed flap and a movable flap whose one end is hingedly connected to the fixed flap. The fixed flap is fixed in the middle of the two guide rods, and the other end of the movable flap is connected to the fixed flap through a detachable connection structure.

One of the moving knife bodies is provided with a first arc-shaped stopper that is adapted to stop and cooperate with the outer peripheral surface of the movable flap when the two moving knife bodies are close to each other; A second arc-shaped stopper that fits and stops with the outer peripheral surface of the fixed flap when the two movable knife bodies are close to each other.

The beneficial effect of the present invention is that: in the present invention, the cable positioning sleeve is fixed on the mechanism seat, and the relative movement of the two movable knife bodies can complete the stripping of the outer steel strands of the cable, and the axis of the cable positioning sleeve is at the position of the line. The core avoidance groove is in the extension direction of the movement track of the groove center, so it can ensure that the cable core is just in the center of the wire core avoidance groove, and the moving knife body is placed on the wrong side to damage the wire core, because the cable positioning sleeve and the seat of the mechanism are fixed. , so there is no wear problem, which can ensure the long-term high-precision use of the cutting mechanism.
