Abstract

The invention belongs to the technical field of flexible guide mechanisms, and discloses a flexible guide part which is high in flexural rigidity and stable and reliable in structure and has good buffering and guiding functions. In addition, the multiple first end heads and the multiple second end heads are evenly distributed around the spiral central axis in the circumferential direction, so that stress on the multiple spiral bodies is more balanced, and the problems of eccentric vibration and the like caused by uneven stress on the flexible guide part are effectively solved. The invention further provides a flexible guide mechanism, the flexible guide mechanism can conveniently and flexibly adjust the number of effective stress turns of the spiral body in the flexible guide piece through the arrangement of the adjusting sleeve and the adjusting ring, and therefore rigidity adjustment of the flexible guide piece is achieved, and the use requirements under different buffering and guide working conditions are met.

Description

technical field

[0001] The present invention relates to the technical field of flexible guide mechanisms, in particular to a flexible guide member, a flexible guide mechanism and a flexible guide device. Background technique

[0002] The flexible guiding mechanism is widely used in precision displacement, precision force control and flexible buffering because it has better buffering and guiding functions and is not easy to generate friction.

[0003] The existing flexible guide mechanisms mainly include springs and flexible hinge mechanisms. The springs have a long stroke, but their bending stiffness is small. Usually, they also need to cooperate with the guide mechanism to realize the buffering and guiding function. In addition, since the spring is spirally wound by a single wire , the force is transmitted through the spring wire, so when the force is applied to the end of the spring, when the spring stroke is long, the spring is easily bent when the force deviates from the...
