Description
Technical Field
The invention relates to the technical field of painting, in particular to an inner cavity painting device, an inner cavity painting method and an inner cavity painting method for a sliding rail sleeve.
Background
The main function of the slide rail sleeve is to provide a motion space for the slide rail in an aircraft wing oil tank, so the slide rail sleeve is usually in a thin-wall, shell-shaped and cantilever beam stressed structure, and the central axis of the slide rail sleeve is consistent with the motion track of the slide rail and is in an arc shape, namely, the arc-shaped axis curved sleeve. In practical use, the structures of the sliding rail sleeves are serialized, but the external dimensions of the sleeves of each specification are limited by the installation positions of the sleeves, so that certain differences are presented. One typical structure of the slide rail sleeve is shown in fig. 1, the diameter of the cylinder body is generally between 100 and 300mm, the wall thickness of the part is between 2 and 6mm, the central axis of the slide rail sleeve is in a spatial arc shape, the radius R of the arc axis is between 500 and 2000mm, and the length H of the slide rail sleeve is between 400 and 700 mm.
The sliding rail sleeve is usually manufactured by welding in sections, and after welding and heat treatment, the surface of the sliding rail sleeve needs to be subjected to corrosion prevention treatment. The common method for painting the sliding rail sleeve at present is to firstly adopt epoxy primer to paint the inner cavity of the sleeve in a filling way, so that the inner cavity is completely cured; spraying oil-resistant paint on the outer surface of the sleeve except the end face of the flange plate, and drying and completely curing; and (4) overturning the geometric position of the sleeve, spraying oil-resistant paint on the flange plate on the outer surface of the sleeve, and drying and completely curing. Of course, the necessary protection of the unpainted areas is required during the painting process. In addition, after the surface of the metal base material of the sliding rail sleeve is subjected to anodic oxidation, painting is finished as soon as possible, and the time is not more than 24 hours; the shorter the interval time, the better the anticorrosion effect.
At present, the inner cavity of the sliding rail sleeve is manually coated or brushed, the variation range of the coating thickness is large and is often multiple times of the spraying thickness difference of the outer surface, namely, the quality consistency is poor, the local coating thickness is often too thick, and a large amount of reworking and repairing are caused, and time and labor are wasted. Meanwhile, the manual pouring or brushing has higher requirements on the operation skills of personnel and has relatively higher operation strength.
Meanwhile, in the process of painting the sliding rail sleeve, the paint layer or the coating needs to be heated to 90 +/-5 ℃ in an oven and the temperature is kept for about 3-4 h. In the whole process of painting the sliding rail sleeve, the paint layer or the coating is completely cured for 3 times, the processing period is long, the efficiency is low, and the waste of energy consumption is correspondingly large. Meanwhile, the appearance of the fish scale pattern is reserved on the surface of the welding line of the sleeve, the pinhole defect of a paint layer or a coating layer often appears on the surface of the welding line, and in order to prevent the defect from influencing the corrosion resistance of the sliding rail sleeve structure, paint repairing treatment is often needed after painting. Drying is also needed after paint repair, which is time-consuming and labor-consuming, and poses a challenge to manual operation.
