Posture adjusting device and posture adjusting method capable of realizing multi-degree-of-freedom motion

Abstract

The invention provides a posture adjusting device and posture adjusting method capable of realizing multi-degree-of-freedom motion. Six-degree-of-freedom motion of a component is realized by utilizinga spiral elevator, a cross sliding table, a tension spring and a ball and ball socket structure. X/Y directional translational motion and A/B/C tri-directional micro-adjustment of an aircraft part can be manually and rapidly adjusted, a Z directional lifting motion and the A directional rotation motion of the aircraft part depend on quantitative adjustment of the spiral elevator, real-time quantitative control is realized, and six-degree-of-freedom motion is realized. The posture adjusting device has high degree of freedom, is precise in butt joint during assembly, can realize quantitative control, and flexible manual quick adjustment during assembly, so that the assembly precision of the aircraft part is greatly improved, and the assembly time is saved. The device may be directly popularized to applications in the butt joint assembly field of 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 CN 103434655 A discloses an aircraft nose landing gear assembly test vehicle, which...

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.
