Embodiment Construction

[0015] Such as figure 1 As shown, a three-dimensional force sensor-based ball-and-twist connection mechanism of a positioner is provided with a three-dimensional force sensor 2 on the positioner 1. Process ball head 4, the upper end of the process ball head is a flange structure, and the lower end is a sphere structure, so that it has the freedom to rotate around the center of the sphere; two laser tracker targets are symmetrically arranged along the diameter direction on the upper surface of the ball twist connection unit 3 5. Used to determine the sphere center coordinates of the craft ball head; the data line of the three-dimensional force sensor 2 is derived through the three-dimensional force sensor connection port 6 at the side end, and the data line communicates with the control system.

[0016] Such as figure 2 As shown, the specific structure of the ball joint connection unit 3 is as follows: the center of the ball holder body 10 is a spherical surface, and the ball hol...

Abstract

The invention relates to a ball-hinged coupling mechanism of a locator based on a three-dimensional force sensor, wherein a three-dimensional force sensor is arranged on a locator; a ball-hinged coupling unit is connected with the three-dimensional force sensor; a process ball head is hinged in the ball-hinged coupling unit; two laser tracker targets are symmetrically arranged on an upper surface of the ball-hinged coupling unit along a diameter direction; and a data wire of the three-dimensional force sensor is led out by a wiring hole of the three-dimensional force sensor on the side. The coupling mechanism integrates the ball-hinged coupling and the three-dimensional force sensor with the locator, achieves quick and accurate coupling of the plane and the locator and coordination control of the locator, not only improves production efficiency, but also reduces assembly stress greatly.

Description

Technical field [0001] The invention relates to a positioner ball-twist connection mechanism based on a three-dimensional force sensor, which is used for the rapid and accurate connection of butt tooling for large parts of an aircraft fuselage, and belongs to the field of aviation manufacturing engineering / aircraft assembly. Background technique [0002] Modern aircraft have the characteristics of long life, stealth, high reliability and low cost and rapid development, which puts forward higher requirements on the manufacturing process and tooling of aircraft. Traditional assembly frames and fixtures can no longer meet the needs, and the development of numerical flexible tooling It is imperative. Numerical flexible tooling based on product digital size coordination system, reconfigurable modularization and automated assembly system design not only reduces tooling development costs, shortens tooling preparation cycle, but also improves assembly efficiency and quality. The flexibl...
