Cable cutting device for flexible cable net of cable antenna

Abstract

The invention discloses a cable cutting device for a flexible cable net of a cable antenna. The cable cutting device is provided with a base; two guiding rail bases are fixed on the left side and the right side of the base through threads correspondingly; and first connecting guiding rails are fixed on the two guiding rail bases correspondingly. A force measuring device is installed at one end of the base. A tension adjusting device is installed on the other end of the base. A sliding table cable pressing device is slidably connected with the first connecting guiding rails arranged on the other end of the base; and a sliding table cable cutting mechanism is slidably connected with the first connecting guiding rails and located between the force measuring device and the sliding table cable pressing device. A sliding block expansion displacement sensor is arranged on the base. According to the cable cutting device for the flexible cable net of the cable antenna, the machining errors of a cable of the cable antenna are effectively reduced, and the working tension which the cable needs can be accurately controlled when the cable is tensioned; the stress on the cable is not affected by the operations of the sliding table cable cutting mechanism when a connector arranged on the other end of the cable is manufactured; and the lengths of needed cables can be precisely controlled through a sliding table cable cutting female table and a sliding table cable cutting table.

Description

technical field [0001] The invention belongs to the technical field of cable-net antennas, in particular to a cable-cutting device for a flexible cable-net of a cable-net antenna. Background technique [0002] The flexible cable net is an important part of the satellite-borne cable net antenna reflector, and the metal wire mesh used as the reflecting surface is fixed by the flexible cable net; the flexible cable net needs to have good forming accuracy to ensure the shape and surface accuracy of the wire mesh; The main error source of the surface accuracy of the cable net antenna is the cutting error of the rope length of the braided cable net, and a small length error will have a great impact on the tension of the rope. At present, the effective way to reduce the error of rope cutting is to accurately cut the length of the rope under different working tensions, and to make ring joints at both ends of the rope, so that the rope can be assembled into a cable net, thereby impro...

Problems solved by technology

[0004] The object of the present invention is to provide a cable cutting device for flexible cable nets of cable net antennas, which aims to solve the problem that the current cable cutting devices cannot easily ensure that a fixed-strength and fixed-length cable can be cut under a stable working tension, resulting in the cutting of the cable length. The problem of relatively large error
