Embodiment approach

[0065] The ball head 1 is fixedly installed on the aircraft component, and there is a cross mark on the bottom of the ball head 1; the locking mechanism 40 is a component including the ball socket 2 and other parts, and is installed on the numerical control positioner through the connecting piece 45; the ultrasonic sensor 41 is fixedly installed On the locking mechanism 40; a cylindrical hole is opened at the bottom of the ball socket 2, just enough for the syringe camera 42 to pass through; the camera fixing part 43 is used to fix the syringe camera 42, the camera fixing part 43 and the locking mechanism 40 Fixed connection; the three-way force sensor 44 is fixedly installed on the locking mechanism 40 .

[0066] Before the large parts of the aircraft are installed, the ball head 1 must be allowed to enter the ball socket 2. Before the ball head 1 enters the ball socket 2, the aircraft components are transported to the vicinity of the designated position by the hoisting syste...

Abstract

The invention provides a self-adaptive positioning method for ball head butt joint, comprising the following steps: a preliminary positioning step: positioning a ball socket (2) in an X-axis direction, a Y-axis direction and a Z-axis direction at a position within a set value range from the ball head (1); Precise positioning step: the ball head (1) enters the ball socket (2), and the position of the ball socket (2) is adjusted so that the stress of the ball socket (2) in the X-axis direction is the same as that in the Y-axis direction. Accordingly, the present invention also provides a devicecapable of realizing the ball head docking adaptive positioning method. The invention enables the ball head to be self-adaptively inserted into the ball socket, realizes the quick and accurate positioning action, and shortens the total installation time of the aircraft.

Description

technical field [0001] The invention relates to the field of docking equipment and the field of aircraft assembly, in particular to a method and device for self-adaptive positioning of a ball joint. Background technique [0002] In the installation and docking of large aircraft components, the use of digital docking is the general trend. In digital docking, the connection between the aircraft and the NC positioner depends on the ball head on the aircraft entering the ball socket of the NC positioner, and through a group of movements in the X, Y, and Z directions of the NC positioner, the aircraft is realized. Adjust the posture of each large component and carry out docking. At present, many enterprises use the positioning method to see by eyes and adjust by hand, which is very inconvenient and difficult to achieve the accuracy required for positioning. Contents of the invention [0003] In view of the defects in the prior art, the object of the present invention is to pr...
