Abstract
The invention discloses a different-plane double-oscillating-bar spatial transmission mechanism. The mechanism comprises a driving oscillating bar and a driven oscillating bar. One end of the driving oscillating bar is hinged to a first base body, and one end of the driven oscillating bar is hinged to a second base body. The first base body and the second base body are located on two crossed planes respectively. The driven oscillating bar is provided with a sliding groove, a sliding block is mounted in the sliding groove, and a ball socket is formed in the sliding block. The other end of the driving oscillating bar is hinged to a drive rod. The other end of the drive rod is of a ball head structure, and is hinged to the ball socket in the sliding block so as to form a spatial sphere lower pair. The different-plane double-oscillating-bar spatial transmission mechanism has the advantage that the problems that a traditional transmission mechanism is large in motion space, rapid acting cannot be achieved, and the motion range and reliability are inversely proportional when large tensile force is transmitted are solved.
Description
Technical field
Be in a space transmission for two forks in two not parallel planes, especially relate to antarafacial double swing-bar spatial mechanism.
Background technique
At present, traditional hinge bar driving mechanism, in order to ensure that the rotation (or swing) of the driving lever by being positioned at a plane is passed to the rotation (or swing) being positioned at another not parallel plane follower lever with it, the two bulb drive links generally forming two ball-joints respectively with driving lever and follower lever by two ends realize.Common driving mechanism has three shortcomings: the first, the spatial motion of two bulb drive link needs larger space; The second, two bulb drive link cannot realize the quick start of motion due to the restriction of structure; Less in range of movement during the larger pulling force of structural type transmission of three, two bulb ball-joint, otherwise bulb and ball-and-socket easily pull.
Summary of the invention
The object of the invention there are provided a kind of antarafacial double swing-bar spatial mechanism.
For achieving the above object, the present invention takes following technical proposals:
Antarafacial double swing-bar spatial mechanism of the present invention, comprises initiatively fork and driven fork; One end and first matrix phase of described active fork are hinged, and one end and second matrix phase of described driven fork are hinged, and first, second matrix described lays respectively in two planes intersecting; Described driven fork offers chute, in described chute, slide block is installed, described slide block offers ball-and-socket; The other end and the drive link of described active fork are hinged, and the other end of described drive link is ball head structure and is hinged with Special composition sphere lower pair with the ball-and-socket on slide block.
The invention has the advantages that solve described traditional driving mechanism space large, cannot start fast, range of movement and reliability are inversely proportional to when transmitting large pulling force problem.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is principle schematic of the present invention.
Embodiment
As shown in Figure 1, 2, antarafacial double swing-bar spatial mechanism of the present invention, comprises initiatively fork 1 and driven fork 2; One end and first matrix 3 of described active fork 1 are hinged, and rotate formation first Plane Rotation secondary around articulating point; One end and second matrix 4 of described driven fork 2 are hinged, and rotate formation second Plane Rotation secondary around articulating point, and first, second matrix 3,4 described lays respectively in two planes 5,6 of intersecting; Described driven fork 2 offers chute 7, in described chute 7, slide block 8 is installed, described slide block 8 offers ball-and-socket; The be hinged the other end of described drive link 9 of the other end of described active fork 1 and drive link 9 is ball head structure and is hinged with Special composition sphere lower pair with the ball-and-socket on slide block 8.
Transmission process of the present invention is as follows:
As shown in Figure 2, initiatively fork 1 turns at Z-X plane internal rotation around articulating point, by transmission of power to drive link 9; Drive link 9 also passes through space sphere lower pair by transmission of power to slide block 8 at Z-X move in plane; Slide block 8 slides in the chute 7 of follower lever 9, drives driven fork 2 to rotate around articulating point in Z-Y plane, completes the transmission of power.
