A device for measuring the structural size of a cable sheath

Abstract

The invention discloses a cable sheath structural size measuring device. The device comprises a base; a control device, a clamping device for clamping a cable and an industrial camera for shooting theend surface of the cable are arranged on the base; the industrial camera is electrically connected with the control device; the clamping device comprises a guide rail; a first clamping block and a second clamping block are connected to the guide rail in a sliding mode; a lead screw parallel to the guide rail is rotationally connected to the base; the lead screw is in transmission connection withthe first clamping block and the second clamping block simultaneously; the first clamping block and the second clamping block approach or move away from each other at the same time when the lead screwrotates; a hand wheel is arranged at one end of the lead screw; and a torque limiter is arranged between the hand wheel and the lead screw. When device of the invention is used for measuring the structural size of a cable sheath, a metal layer does not need to be stripped from the sheath, and therefore, the sheath is prevented from being damaged or deformed, and measurement accuracy is improved.

Description

technical field [0001] The invention relates to a measuring device, in particular to a measuring device for the structural dimension of a cable sheath. Background technique [0002] The cable usually includes a sheath, a metal layer, and a wire. The sheath is wrapped around the wire, and the metal layer is attached to the inside of the sheath to enhance the strength of the sheath. The sheath is usually made of insulating rubber material. On the one hand, the sheath protects the internal wires, and on the other hand, it plays the role of insulation and isolation. During the cable production process, the cross-sectional dimensions of the sheath (the outer diameter of the sheath, the inner diameter of the sheath, and the thickness of the sheath) need to be measured. The traditional measurement method needs to take a section of the sheath first, peel off the metal layer inside the sheath, then cut the sheath into thin slices, and put it into a special device for measurement. ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that before measuring the structural size of the cable sheath, the metal layer inside the sheath needs to be peeled off first. When the metal layer is peeled off, the sheath is easily deformed, and the sheath is easily damaged, resulting in a measurement structure. Inaccurate problem, provide a cable sheath structure size measurement device, no need to peel off the metal layer before measurement, the measurement structure is accurate
