Device and method for positioning overall frame of airplane

Abstract

The invention belongs to the technical field of aircraft assembly, and particularly relates to a device and method for positioning an overall frame of an airplane. The positioning device comprises a sliding sleeve, a refined bolt, a nut, a compression nut, a flange plate and a sliding pin; the sliding sleeve is of a lug-shaped structure, mounting holes are formed in the two ends of a lug, and the sliding sleeve is fixed to the mounting base body in cooperation with refined bolts and nuts. The axis of the sliding sleeve is of a sleeve type structure, a semi-arc boss is arranged at the end of the axis, and a clamping groove is formed in the boss. The sliding pin is a step shaft, and shaft sections with the smallest diameter and the second smallest diameter are provided with threads and are matched with the compression nut and the flange plate respectively. An annular boss is arranged on the shaft section, with the maximum diameter, of the pin shaft, and a notch is formed in the annular boss. The sliding pin is rotated, so that the annular boss is matched with the clamping groove in the sliding sleeve, and locking and disengaging of the sliding pin are achieved. The device can be used for effectively positioning and assembling the whole frame of the airplane, and the purposes of simple manufacturing, convenient use and accurate positioning are achieved. And meanwhile, the in-rack occupation time is reduced, and the assembly efficiency is improved.

Description

Technical field [0001] The present invention belongs to the field of aircraft assembly, and more particularly to devices and methods for the overall frame positioning of aircraft. Background technique [0002] For a long time, the plane is assembled in the form of a displacement. The method is: First, in the frame (or web) in the frame (or web), follow the box on the box and the frame (or web) and the aircraft's space geometric dimension, order to complete the assembly . Since the number of dispersions is large, the position is dispersed, resulting in a long time to take advantage of the assembly period, which reduces production efficiency; the dispersion positioning of each frame also leads to inaccurate the positioning of the entire frame, and the product is not easy to remove after assembly. With the increase in bulk demand for airplane production, this method has become more and more unable to meet the production line demand. [0003] In view of such a situation, it is necess...

AI Technical Summary

Problems solved by technology

Due to the large number of parts and scattered positions, the assembly period occupied by them in the rack is long, which reduces the production efficiency; the scattered positioning of each frame also leads to inaccurate positioning of the entire frame, and the product is not easy to remove from the shelf after assembly

With the increasing demand for aircraft production batches, this method has become less and less able to meet the needs of production line assembly
