Process for controlling thickness of glued rubber layer by using self-made rubber cover plate

Abstract

The invention relates to a process for controlling a thickness of a glued rubber layer by using a self-made rubber cover plate. The process comprises the following steps: 1) a balance plate is manufactured; 2) a rubber film is paved on a prebonded cover; then, a reinforcing plate is placed on the rubber film for buckling the balance plate; and the balance plate extends out around stripping cloth and a porous isolation film; 3) the balance plate is connected and positioned with a reinforcing plate by a pin; and 4) the integer in the steps 2) and 3) is sealed with a vacuum bag, and is shifted into a hot pressing tank; the pressure is applied to the top of the balance plate; the curing is performed by heating; and a cover glued layer with uniform thickness is obtained after curing. The process uses the rubber balance plate for realizing secondary uniform distribution of the pressure of the hot pressing tank, weakens the influence on the thickness of the rubber layer by matching between molding surfaces of the reinforcing plate and the cover compared with direct acting of the pressure on the reinforcing plate, and obtains the rubber layer with uniform thickness. The operation of using the balance plate is simple; the positioning is accurate; the self-inspection is convenient; the process and the result both achieve visible and controllable effects; and the product quality and the working efficiency are improved.

Description

technical field [0001] The invention relates to a technology for controlling the thickness of the glued glue layer by using a self-made rubber cover plate, which is used for the glued thickness control technology of the glued bond between aircraft skin and reinforcement board. Background technique [0002] During the gluing process of the middle panel of a certain type of aircraft empennage tip and flat tail stabilizer, due to the large tolerance of the skin and the reinforcement plate, it is easy to cause uneven cooperation between the skin and the reinforcement plate, resulting in The thickness of the adhesive layer between the middle skin and the reinforcement plate varies greatly, which exceeds the value required by the specification, resulting in the delay in the successful development of the part, which not only causes great economic losses, but also leads to customer dissatisfaction.
