The invention discloses an aircraft outer wing airtight and oil-tight test device and method, and belongs to the technical field of aeronautical manufacturing, and the device comprises a turnover mechanism, a connecting flat plate, a support, a visual control cabinet and an oil circulation system. An innovative automatic control turnover mechanism is adopted, visual automatic control over outer wing pitching posture adjustment and turnover posture adjustment during outer wing airtight and oil-tight test and turnover cleaning is achieved, and the turnover mechanism is reasonable in design and accurate in control. The connecting flat plate shared by the left outer wing and the right outer wing improves the situation that a large amount of manpower and material resources are wasted when the flat plate is replaced repeatedly, and production efficiency is improved. The oil circulating system greatly simplifies the processes of oil adding, oil discharging and circulating cleaning in the test process, and saves a large amount of oil consumption cost. The problems that traditional outer wing airtight oil-tight and cleaning equipment is difficult to control, poor in control precision, tedious in test process, low in production efficiency and large in oil consumption are solved.
Description
technical field [0001] The application belongs to the technical field of aviation manufacturing, and in particular relates to an air-tight and oil-tight test equipment and method for an outer wing of an aircraft. Background technique [0002] The air-tightness and oil-tightness test of the outer wing of a medium-sized transport aircraft and the cleaning of the fuel tank are important processes in the production process of the outer wing. It is used to test the sealing performance of the outer wing fuel tank, and the fuel tank is fully cleaned so that the internal cleanliness can meet the final assembly requirements. [0003] During the air-tight and oil-tight test and cleaning process of the outer wing, it is necessary to control the tip of the outer wing to pitch to a specific angle, and it is required to be able to control the outer wing to turn 180° to complete the comprehensive inspection and cleaning of the outer wing. The outer wing of a certain type of aircraft is mor...
