An automatic brushing device for c/c material surface

Abstract

The invention relates to an automatic brushing device for the surface of a C / C material. The automatic brushing device comprises a rail car, and a driving motor is mounted on a chassis of the rail car; the driving motor provides forward moving driving force for the device; a delivery pump is mounted on the rail car; one end of the delivery pump is connected with a paint box through a feeding pipe; the other end of the delivery pump is connected with a brush carrier through a discharge pipe; during the forward moving process of the rail car, the delivery pump continuously transports paint into a brushing mechanism; the delivery pump is equipped with a flow regulating valve used for controlling flow velocity of paint; paint passes through the discharge pipe, flows through the brush carrier, and finally is uniformly smeared onto brush hair; and the brush hair uniformly smears the material surface with paint under the driving of the rail car. The automatic brushing device can achieve the function of uniformly and quickly smearing surfaces of C / C samples, and has the advantages of being convenient and quick in use, low in labor intensity, high in brushing speed, and good in brushing effect.

Description

technical field [0001] The invention relates to the field of C / C composite material surfaces, in particular to an automatic brushing device for C / C material surfaces. Background technique [0002] C / C composite material is a new type of high-strength, high-toughness, and high-temperature-resistant structural material. It has been widely used in solid rocket motor nozzles, space shuttle structural components, aircraft brakes, and hot-end components of aero-engines. However, due to the poor high-temperature oxidation resistance of C / C composites, there are large voids inside, resulting in unsatisfactory high-temperature mechanical properties. Therefore, it is necessary to add an anti-oxidation coating to its surface. The brushing method is to borrow the idea of ​​surface sticking, that is, to form a functional coating on the surface of the sample through a special adhesive, but at present, the brushing of the C / C surface is mainly done by manual brushing, which is labor-inten...
