Embodiment Construction

[0035] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0036] A kind of helicopter cockpit cover bonding and assembly method, such as figure 1 shown, including the following steps:

[0037] Step 1: Pre-installation: Position the left door frame frame, right door frame frame, left windshield frame, right windshield frame, upper corner joint, lower corner joint, cockpit ceiling, and ventilation pipe-shaped parts on the assembly fixture in sequence according to the positioning reference; measure each part The gap between the board and the pallet;

[0038] The second step: make the initial hole, make the left door frame frame, the right door frame frame, the left windshield frame, the right windshield frame, the upper corner joint, the lower corner joint, the cockpit ceiling, and the initial holes for connecting the ventilation pipe parts;

[0039] The third step: riveting ...

Abstract

The invention belongs to the technical field of composite material assembling and manufacturing, and discloses a helicopter cockpit cover gluing assembling method and a clamp. A brand-new tool form for curing and assembling a cockpit cover is adopted, an embedded separable tool structure is provided, a simple curing bracket is changed into a curing clamp tool with an appearance clamping plate, a curing clamp and an assembling clamp form a whole in the assembling process, and the curing clamp can be separated from the assembling clamp in the curing process. An INVAR steel material with the expansion coefficient similar to that of a composite material is selected as a curing clamp tool material, and deformation of the cockpit cover in the curing process is effectively controlled; and meanwhile, the positioning reference of the cockpit cover is transferred to the curing clamp from the assembling clamp so that the unification of the positioning reference of the cockpit cover in the pre-assembling, curing and assembling processes is ensured, the off-frame frequency of the cockpit cover is reduced, and the deformation of the cockpit cover in the curing process is effectively controlled.The problems that a butt joint assembling gap between the cockpit cover and a fuselage is out of tolerance, and assembling with a cockpit door and a radome is not coordinated are solved.

Description

technical field [0001] The invention belongs to the technical field of composite material assembly and manufacturing, and in particular relates to a helicopter cockpit cover adhesive bonding assembly method and a fixture. Background technique [0002] Helicopter canopy is a typical part with the characteristics of helicopters. Currently, it is mainly made of advanced composite materials, including left door frame frame, right door frame frame, left windshield frame, right windshield frame, cockpit roof, upper corner joint, lower corner joint, front belt plate, The back is equipped with components such as plates, and the overall structure is formed by glue riveting. The non-closed structure of the weak skeleton has the characteristics of space distortion, small rigidity, and easy deformation. [0003] At present, the canopy assembly of existing models includes two sets of independent tooling, the assembly fixture and the curing bracket. After the canopy is pre-installed and...
