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

Embodiment Construction

[0018] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0019] Such as figure 1 As shown, a universal compliance mechanism includes an inner ring body 1, an outer ring body 2 and an elastic body 3, the inner ring body 1 is arranged in the outer ring body 2, and the elastic body 3 is arranged on the inner ring body 1 and the Between the outer ring body 2, the elastic deformation of the elastic body 3 serves as the restoring tension for the relative translation, rotation and overturn between the inner ring body 1 and the outer ring body 2, between the inner ring body 1 and the outer ring body 2 There is a gap between them, and the gap at least ensures that the relative translation, rotation and flipping strokes between the inner ring body 1 and the outer ring body 2 do not interfere within the elastic deformation range of the elastic body 3. In this embodiment, at right angles to the space ...

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 obedience device can be installed in conjunction with some fixtures, movable or stationary parts in automated production. In the production process, when these matched parts encounter obstacles in motion, the obedience device can perform flexible avoidance through the obedience device to realize the obedience 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 original position when the force is small or no force is applied. 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 stee...
