AI Technical Summary

Technical Problem

Under conditions of high-speed reciprocating motion and frequent start-stop operation, the contact stiffness of the guide pair interface cannot be adaptively adjusted due to thermal deformation, load fluctuation and media intrusion, which affects the motion accuracy and stability. Furthermore, kinetic energy fluctuation causes torsional vibration of the crossbeam. Existing technologies make it difficult to achieve active management without an external power source.

Method used

A purely mechanical adaptive system is adopted, which achieves the follow-up optimization and kinetic energy management of the guide pair by adaptive adjustment of interface gap and absorption and redistribution of system kinetic energy, respectively, from the two dimensions of motion constraint stability and driving stability.

Benefits of technology

It significantly improves the dynamic motion accuracy and system stability of the robot under extreme working conditions, avoids the limitations of traditional methods, and achieves high-precision repeatability positioning and lightweight design without the need for an additional power source.

Abstract

The application relates to the technical field of automatic mechanical hand and discloses an automatic gantry type mechanical hand device, which comprises a moving frame. According to the scheme, two sets of pure mechanical self-adaptive systems are cooperatively used to improve the dynamic motion precision and system stability of the mechanical hand under high-speed and frequent start-stop working conditions. On one hand, through self-adaptive regulation of the interface gap, the follow-up optimization of the contact stiffness of the guide pair is realized, and the motion instability risk is eliminated from the source; on the other hand, through the absorption and redistribution of the system kinetic energy, the dynamic disturbance of the cross beam is inhibited. The two sets of systems cooperatively act from two dimensions of motion constraint stability and motion drive stability, so that the mechanical hand can still realize high-precision repeated positioning under the limit working condition, and the comprehensive effect is obviously better than that of the simple superposition of the functional modules.
