Embodiment Construction

[0036]Below in conjunction with accompanying drawing and embodiment the present invention is described further, but the present invention is not limited to this embodiment.

[0037] A skin adaptive adsorption clamping device is suitable for clamping aircraft skins of various shapes and sizes, and includes a frame A, a bent frame B and an adaptive adsorption column C. Such as figure 1 As shown, the upper and lower beams of the frame are respectively equipped with racks; the bent frame is located between the upper and lower beams. The motor I that moves horizontally on the frame, the synchronous movement of the two motors I can make the rack move along the rack on the frame, and the racks need to move in coordination to avoid interference; the racks are equipped with ball wires along the vertical direction Each set of racks is equipped with a certain number of self-adaptive adsorption columns, and each adaptive adsorption column can move up and down along the vertical guide rai...

Abstract

The invention discloses a self-adaption absorptive clamping device of an airplane skin. The clamping device is characterized by comprising a frame, bent frames and self-adaption absorptive columns, wherein the upper and lower beams of the frame are provided with racks, and the two ends of each bent frame are arranged on the racks and can move along the racks; each bent frame is internally provided with a linear guide rail in a vertical direction, and each group of bent frames is provided with a certain amount of self-adaption adsorption columns and can move along the linear guide rail respectively; each adsorption column comprises a rotary vacuum chuck, a self-adaption telescopic link and a scale column. According to the clamping provided by the invention, the layout of the bent frames and the self-adaption absorptive columns can be adjusted by aiming at the shape of the skin, the absorption height can be adjusted by the scale columns and the self-adaption telescopic links, and the skin can be absorbed by the vacuum suckers; furthermore, the clamping device is applicable to clamping the skins of various shapes and sizes, the comprehensive cost can be reduced, the frock preparation period and production period can be shortened, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to a clamp, in particular to an aircraft skin clamping device, in particular to an aircraft skin self-adaptive adsorption and clamping device. Background technique [0002] Aircraft skin is the outer part that constitutes the aerodynamic shape of the aircraft. It has large size, many types, complex and diverse shapes, and small batches. It is an important part to ensure the aerodynamic performance of the aircraft. In the process of aircraft manufacturing, it is necessary to carry out various processing on the skin. Due to the poor rigidity and small thickness of the skin, it is easy to deform during processing. The existing skin processing usually adopts a multi-point flexible adsorption clamping system. When the skin is formed, certain errors will occur. The existing multi-point flexible adsorption devices usually use motors or hydraulic pressure to precisely control the adsorption position, and locate the adsorption points accor...
