An attitude adjustment device and an attitude adjustment method for realizing multi-degree-of-freedom motion

Abstract

The invention provides an attitude adjustment device and an attitude adjustment method for realizing multi-degree-of-freedom movement, and realizes six-degree-of-freedom movement of components by using a spiral elevator, a cross slide, a tension spring, and a ball-and-socket structure. The X / Y translational movement of aircraft parts and the micro-adjustment of A / B / C three directions can be quickly adjusted manually; the Z-direction lifting movement and A-direction rotation movement of aircraft parts rely on the quantitative adjustment of the screw elevator to realize real-time quantitative control. Realize six degrees of freedom movement. The attitude adjustment device has a high degree of freedom, accurate docking during assembly, quantitative control during assembly, and flexible manual quick adjustment, which greatly improves the assembly accuracy of aircraft components and saves assembly time. It can be directly extended to the field of butt joint assembly in other industries.

Description

technical field [0001] The invention relates to the field of docking installation of large aircraft parts in the aviation manufacturing industry, in particular to a device and method for fast and accurate docking installation of large aircraft parts. Background technique [0002] At this stage, the attitude adjustment device or assembly test device used in the field of docking and assembly of large aircraft parts is not flexible enough in structure freedom, and the operation is manually operated and the docking is difficult, which not only consumes time and affects the assembly accuracy of large aircraft parts, but also affects the aircraft and personnel safety. The posture adjustment device with multi-degree-of-freedom movement is flexible in operation, capable of three-dimensional movement and three-dimensional rotation, and realizes six-degree-of-freedom movement in space. [0003] Patent CN103434655A discloses an aircraft nose landing gear assembly test vehicle, which i...

AI Technical Summary

Problems solved by technology

The above technology uses motion superposition to realize six-degree-of-freedom motion. The X / Y / C axis can be adjusted manually, but its degree of freedom cannot be quantitatively adjusted; although the Z / A / B axis can be quantitatively controlled through servo control, it lacks the requirements for flexible assembly , it is impossible to quickly complete the handling and posture adjustment of the whole mechanism

At the same time, this structure is difficult to control and highly dependent on system control. If one of the four electric cylinders has a problem, it cannot be used normally and must be replaced, and the purchase cost is relatively high.
