Abstract

The invention discloses a method and a device for precisely positioning a large part of an airplane in place. The device is arranged in a transition part of connecting a positioner and the large part of the airplane; the positioner is a modularized unit which can realize motion in three mutual vertical directions and has high positioning precision and reliable work; through certain configuration,effective support and posture adjustment on the large part of the airplane can be formed. The device for precisely positioning the large part of the airplane in place has a positioner supporting plate; the bottom of the positioner supporting plate is provided with a sensor fixing bracket; the sensor fixing bracket is provided with four liner displacement sensors; the upper part of the positioner supporting plate is provided with a pressing plate; the top part of the pressing plate is provided with an emitter bracket; the emitter bracket is provided with a plurality of laser emitters; the inside of the positioner supporting plate is provided with a ball strut which is in interference fit and connection with an inner hole of the positioner supporting plate; the outer side of the positioner supporting plate is provided with a plurality of cylinders; and a piston rod of each cylinder is connected with a locking square cotter. The method and the device have simple operation, high positioning precision, good safety and reliable positioning algorithm.

Description

technical field [0001] The invention relates to an accurate positioning device and method for large parts of an aircraft. Background technique [0002] Traditional aircraft assembly uses a large number of jigs and fixtures for clamping and positioning, and transmits the shape and size of parts in the form of analog quantities, which has become the weakest link in the aircraft manufacturing process in my country. At present, the aircraft digital assembly technology that is booming abroad is based on the synthesis of various advanced technologies such as digital standard tooling technology, digital simulation technology, laser tracking measurement technology, digital positioning technology, and collaborative control technology. In the digital environment, the traditional manual docking platform has been replaced by a flexible docking platform composed of a computer-controlled digital locator and a laser tracking and positioning system. [0003] In the process of aircraft digi...
