Embodiment Construction

[0019] This embodiment is an experimental device for positioning and clamping aircraft thin-walled parts.

[0020] refer to Figure 1 to Figure 5 , The experimental device of this embodiment is composed of a plurality of positioners 4, a plurality of holders 5, a leveling support 3 and a support frame. The support frame structure is composed of crossbeam 1, vertical support beam 17, connecting beam 2 and connecting plate. The connecting plate includes an upper connecting plate 14, a middle connecting plate 15 and a lower connecting plate 16. The upper connecting plate 14 and the lower connecting plate 16 have the same structure; The four vertical beams 17 are fixedly connected to the four beams 1 respectively, and the multiple connecting beams 2 are fixedly installed on the upper surface of the upper beam 1 and the upper surface of the lower beam 1 of the support frame in parallel, and the connecting beams 2 on the upper surface of the upper beam 1 are connected to the lower b...

Abstract

The invention discloses a locating and gripping experimental device for aircraft thin-wall parts. Cross beams, vertical supporting beams, a connecting beam and a connecting plate are adopted to form a supporting frame structure; the four vertical supporting beams fixedly connected with the four cross beams, respectively; the plurality of connecting beams are fixed on the upper surfaces of both the upper cross beams and the lower cross beams of the supporting frame in parallel; the connecting beams on the upper surfaces of the upper cross beams and the connecting beams on the upper surfaces of the lower cross beams are mounted in a relatively dislocated way; every two grippers are fixed on the side surfaces of the upper connecting beams of the supporting frame; every two locators are fixed on the side surfaces of the lower connecting beams of the supporting frame; gripping heads of the grippers and locating heads of the locators are coaxial with each other so as to oppositely locate and grip the thin-wall part; and four levelling supports are symmetrically mounted on the lower surfaces of the lower cross beams of the supporting frame and used for adjusting the supporting frame to a horizontal posture. The locating and gripping experimental device for the aircraft thin-wall parts, disclosed by the invention, is advantaged in that the experimental device is simply structured and capable of locating and gripping the thin-wall parts with different shapes and sizes; and as the locators and the grippers are configured in a modularized way, the locating and gripping experimental device is highly adaptive and reconfigurable.

Description

technical field [0001] The invention belongs to the field of aircraft manufacturing assembly and process equipment, and in particular relates to an experimental device for positioning and clamping aircraft thin-walled parts. Background technique [0002] Aircraft thin-walled parts are the main structural parts constituting the aerodynamic shape of the aircraft, which have the characteristics of large size, complex shape and weak rigidity. The assembly process of aircraft components mainly includes positioning, clamping, hole making, and connection. Thin-walled parts are large in size and easy to deform. Reasonable positioning layout and clamping force are the prerequisites for controlling their deformation and accurate assembly in subsequent processes. Therefore, it is necessary to study the influence of positioner layout and clamping force on the deformation of thin-walled parts. Correspondingly, an experimental device is needed to analyze the feasibility and effectiveness...
