Stabilizing device before cutting off cable by utilizing stroke changing principle

Abstract

The present invention discloses a stabilizing device before cutting off a cable by utilizing a stroke changing principle, and relates to the technical field of cable production and manufacturing. Thedevice comprises a base, a positioning hole is formed in the base, and three positioning blocks are fixedly connected to the front face of the base. Limiting blocks are fixedly connected to the outersides of the positioning holes, push rods are movably connected in the limiting blocks, and clamping mechanisms are movably connected in the positioning blocks. According to the stabilizing device before cutting off the cable by utilizing the stroke changing principle, a handle is pulled anticlockwise to drive a driving wheel to rotate, at this time, the movement stroke of a connecting rod is reduced, the stroke for correspondingly driving the push rod to move is reduced, and the distance among the three rotating wheels is increased. The device is suitable for the cable with larger size, according to the structure and the process, the purpose that the distance of the device is variable is achieved, the device can be suitable for cables of different specifications through the variable-distance structure, the application range of the device is enlarged, and the practicability and the applicability of the whole device are improved.

Description

technical field [0001] The invention relates to the technical field of cable manufacturing, in particular to a stabilizing device before cable cutting using the principle of stroke change. Background technique [0002] In order to facilitate transportation and measurement, cables are usually produced in the form of wire bundles when they leave the factory. When laying cables, it is often necessary to cut cables of corresponding lengths according to different construction lengths. Since the cross-sectional shape of cables is generally circular and The surface is a smooth insulating layer. When shearing, the cable will move as a whole due to the tension. At this time, the cut will be uneven, resulting in the need for secondary cutting when the cable is connected, which takes a certain amount of time. At the same time, if the cable moves when it is cut, the contact area between the cutter and the insulating layer will increase, which will cause the insulating layer to rupture, ...
