A Universal Compliance Mechanism

Abstract

The invention provides a universal obedience mechanism which comprises an inner ring body, an outer ring body and elastic bodies, wherein the inner ring body is arranged in the outer ring body; the elastic bodies are arranged between the inner ring body and the outer ring body; the elastic deformation of the elastic bodies serves as the restoring tension for the relative translation, rotation andoverturning between the inner ring body and the outer ring body; gaps are reserved between the inner ring body and the outer ring body; and through the gaps, it is at least guaranteed that no interference is generated in the elastic deformation range of the elastic bodies in the stroke of relative translation, rotation and overturning between the inner ring body and the outer ring body. The universal obedience mechanism provided by the invention can not only provide translation compensation for the X-Y-Z linear directions but also provide rotation compensation for the three axial directions A-B-C corresponding to the X-Y-Z linear directions; furthermore, the reliability and the precision are high; and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of automatic production testing equipment, in particular to a universal compliance mechanism. Background technique [0002] The compliance device can be installed with some fixtures, movable or stationary parts in automated production. In the production process, when these matched parts encounter obstacles in movement, the compliance device can be used to flexibly avoid and achieve the compliance function. A reset mechanism needs to be provided in the compliance device, so that the movable part of the compliance device can automatically return to the initial position when the force is small or not. Among the existing compliance and reset mechanisms, one uses rubber to provide torque to achieve compliance and reset, which is relatively heavy in weight and volume, and the other uses steel plate bending to provide reset torque, but because the steel plate is easy to wear, the reset torque is reduced. There is ...

Problems solved by technology

Among the existing obedience and reset mechanisms, one is to use rubber to provide torque to achieve obedience and reset, which is relatively large in weight and volume, and the other is to use steel plate bending to provide reset torque, but because the steel plate is easy to wear, the reset torque There is a downward trend, the reset accuracy cannot be guaranteed, and they have fewer reset directions and more structural restrictions, and cannot achieve reset in any direction
