Small film rolling machine used for spacecraft hot test electrical fitting technology

Abstract

The invention discloses a small-sized film rolling machine used for the thermal test electrical assembly process of spacecraft, which includes a base, a rotating shaft frame, an auxiliary shaft frame, a film rolling roller, a rocker, etc.; wherein, a rolling bearing is arranged on the rotating shaft frame After the rocker passes through the bearing, the variable diameter section is used to ensure close contact with the inner ring of the bearing; a pin hole is provided on the rocker on the side passing through the bearing, and the pin penetrates into the pin hole; a limit groove is provided at one end of the roll film roller When in use, the pin snaps into the limit slot, and the other end of the roll film roller is set on the extension rod of the auxiliary shaft frame; the straight rod is extended from the film fixing bracket fixed on the other end of the base and parallel to the roll film roll, The front end is provided with a 90° elbow, which is used to cover the polyester film sleeve on the straight rod of the film fixing bracket. The invention is designed to be light and simple, can quickly roll the polyester film, and improves the work efficiency of craftsmen.

Description

technical field [0001] The invention belongs to the technical field of spacecraft thermal test tooling, and is applied to the rolling work of the polyester film of the electrical equipment process before the spacecraft thermal test. It is better to complete the polyester film roll faster. Background technique [0002] At present, domestically developed film rolling machines are mostly used in large-scale industrial manufacturing, and small, simple and smart film rolling machines have not yet been used in spacecraft thermal test electrical assembly processes. [0003] In the market, film rolling machines are mostly large-scale industrial equipment, hiding in large-scale papermaking industries and plastic film processing industries. Its size and configuration are relatively large, and its self-weight is relatively large. It is a non-movable production equipment. [0004] In the preparation work of the electrical installation process, in order to facilitate the operation, it ...

AI Technical Summary

Problems solved by technology

In the past, the film roll operation was carried out by craftsmen holding a short rod to wind and roll the polyester film. This method is not only time-consuming, but also low in efficiency.
