Abstract
The invention relates to a three-degree of freedom hinge. A first branched hinge is hinged with a second branched hinge through a shaft pin, and the shaft pin is connected with an external part. One end of a first card slot is hinged with the first branched hinge through a first bolt, and the other end of the first card slot is hinged with the external part through a second bolt. The axes of two ports of the first card slot are vertical. One end of a second card slot is hinged with the second branched hinge through a third bolt, and the other end of the second card slot is hinged with the external part through a fourth bolt. The axes of two ports of the second card slot are vertical. The three-degree of freedom hinge has the advantages of simple structure, convenience in manufacture and high reliability, is controllable and adjustable, has the function of a ball hinge, and can flexibly-tuned input according to the demand or environmental change to accurately realize rotation actions.
Description
Technical field
The present invention relates to the hinge design field, particularly a kind of Three Degree Of Freedom hinge.
Background technique
Along with the raising of mechanical automation level, it gradually serves as extensively that hinge uses it with its advantage at aspects such as mechanical structure, Applicable scope, flexibilities, and becomes a kind of development trend, is widely used in various mechanical transmission.When spherical pair often appeared at the joint of mechanism's driving link, particularly driving link and frame and spherical pair occurs, control brought many inconvenience to motion of mechanism.Spherical hinge can't be realized ACTIVE CONTROL because almost control unit can't be installed, and spherical hinge generally also only is applied in passive occasion simultaneously.Have not yet to see and relevant both had the spherical hinge function, have again simple in structure, be convenient to make, the hinge innovation design of premium properties such as controllable, reliability height.
Summary of the invention
The purpose of this invention is to provide a kind of Three Degree Of Freedom hinge, it had both had the spherical hinge function, have again simple in structure, be convenient to make, premium properties such as controllable, reliability height, can be according to the variation of function requirement or environment, the flexible accent imported, and accurately realizes rotation action.
The present invention achieves the above object by the following technical programs:
A kind of Three Degree Of Freedom hinge comprises hinge side chain, latch, draw-in groove and pivot pin.
Described hinge side chain comprises the first hinge side chain and the second hinge side chain, and the first hinge side chain and the second hinge side chain are hinged by pivot pin, and pivot pin is connected with exterior part.
Described latch comprises first latch, second latch, the 3rd latch and the 4th latch.
Described draw-in groove comprises first draw-in groove and second draw-in groove, one end of first draw-in groove is hinged by first latch and the first hinge side chain, the other end of first draw-in groove is hinged by second latch and exterior part, the two-port axis normal of first draw-in groove, one end of second draw-in groove is hinged by the 3rd latch and the second hinge side chain, the other end of second draw-in groove is hinged by the 4th latch and exterior part, the two-port axis normal of second draw-in groove.
Working principle and process: realize first revolute pair by the first hinge side chain and the hinged pivot pin of the second hinge side chain, hinged by second latch and exterior part, utilize the rotation of first draw-in groove to realize second revolute pair, hinged by the 4th latch and exterior part, utilize the rotation of second draw-in groove to realize the 3rd revolute pair, three revolute pairs accurately realize rotation action under the link of the first hinge side chain and the second hinge side chain, make described Three Degree Of Freedom hinge have controlled, adjustable, performances such as output flexibility, make hinge adapt to different task, flexible Application is in different occasions and different targets.
Outstanding advantage of the present invention is:
1, hinge of the present invention is Three Degree Of Freedom compound hinge mechanism, realizes the function of spherical pair by revolute pair, and it has characteristic simple in structure, that be convenient to make.
2, hinge can be according to the variation of function requirement or environment when being used, and soft readjustment input accurately realizes rotation action, and is controllable, reliability is high.
