Aircraft skin part hoisting tool structure

Abstract

The invention provides an aircraft skin part hoisting tool structure. The aircraft skin part hoisting tool structure comprises a mounting bottom plate. The four corners of the bottom of the mounting bottom plate are fixedly connected with mounting fixing pieces correspondingly. Two lifting connecting plates are fixedly connected to the top of the mounting bottom plate, and lifting devices are fixedly connected to the two lifting connecting plates correspondingly. Navigation devices are connected to the two lifting devices in a sliding manner, and driving devices are connected to the navigation devices in a sliding manner. The driving device is provided with a pedestal body device in a rotational coupling manner, the pedestal body device is fixedly connected with a connecting base, and the connecting base is fixedly connected with a supporting large arm through bolts. An elastic adjustment device is arranged, adjusting springs are arranged on adjusting sliding shafts in a sleeving manner and can stretch out and draw back, the problem that skin is scratched due to too tight fixing can be avoided, angle adjustment can be conducted according to the surface curvature of the skin through a vacuum suction cup, and the problem that the skin of a small aircraft cannot be firmly fixed due to a curved surface is solved.

Description

technical field [0001] The invention belongs to the technical field of aircraft assembly, and more specifically relates to a hoisting tooling structure for skin parts of an aircraft. Background technique [0002] Aircraft refers to a plane with one or more engines. The aircraft skin refers to a three-dimensional component that surrounds the aircraft skeleton structure and is fixed on the skeleton with adhesives or rivets to form the aerodynamic shape of the aircraft. The skin structure composed of aircraft skin and skeleton has a large bearing capacity and rigidity, but its own weight is very light, and it plays the role of bearing and transmitting aerodynamic load. Aircraft assembly is an important link in aircraft manufacturing. The coordination between tooling, tooling and tooling, and then the aircraft manufacturing coordination method to ensure the accuracy of assembly is an important feature of aircraft manufacturing. Through a series of special process equipment, the...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides an aircraft skin parts hoisting tooling structure to solve the problem that there is a corresponding protective and stabilizing device for the skin assembly of small aircraft, which is very easy to cause damage to the skin, leading to scrapping and affecting painting. As a result, there is no automatic adjustable fixing device for the curved skin, and the curved skin cannot be hoisted firmly. At the same time, there is no multi-axis adjustment system for the operator to realize flexible steering and movement. Secondly, the structure is too complicated and the manufacturing cost is high. , operating complex problems
