Abstract
The utility model provides a kind of Universal hinge structure for parallel machine, includes mounting seat, swings ball axis, bearing, swing seat, oscillating rod；The mounting seat is concave base construction, is ball-and-socket shape in the middle part of the mounting seat, and two relative side is equipped with wall structure；The swing ball axis is divided into two parts, it is connection shaft and sphere axis respectively, wherein connection shaft is connected to the two relative side of sphere axis and is connected by the wall of bearing and mounting seat, and sphere shaft portion then by with connect bearing of the shaft in horizontal plane direction and be connected with swing seat；The swing seat is the hollow ball socket structure for being rolled in the sphere shaft portion side and top surface that swing ball axis outside, which is groove structure in connection shaft position；The oscillating rod is that one end is connected on swing ball axis, and the other end runs through the connecting rod structure at swing seat center, which is connected through a screw thread with swing seat.
Description
Technical field
The utility model relates to technical field of mechanical transmission more particularly to a kind of universal coupling knots for parallel machine
Structure.
Background technique
The hinge of parallel machine is the component between connecting rod and moving platform, and function is to provide around a certain centre of motion
Rotation and transmitting realize movement needed for power.The mechanism is the turning joint of parallel machine, to the work essence of parallel machine
Degree has a great impact, and the accuracy of manufacture is more demanding.Mostly with spherical hinge and universal in common parallel machine linkage
Based on hinge.Since structure is complicated, is difficult to manufacture for parallel machine universal coupling artis, the prominent of all parallel machines is become
It goes wrong.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of ten thousand for parallel machine are provided
To hinge arrangement, the structure is with good stability, guarantees the running precision of parallel machine, and structure is simple, easy to use.
A kind of in order to achieve the above purposes, the technical solution adopted by the utility model is: universal coupling for parallel machine
Structure includes mounting seat, swings ball axis, bearing, swing seat, oscillating rod；The mounting seat is concave base construction, should
It is ball-and-socket shape in the middle part of mounting seat, and two relative side is equipped with wall structure；The swing ball axis is divided into two parts, respectively
It is connection shaft and sphere axis, wherein connection shaft is connected to the two relative side of sphere axis and by bearing and mounting seat
Wall connection, and sphere shaft portion then by with connect bearing of the shaft in horizontal plane direction and be connected with swing seat；It is described
Swing seat is the hollow ball socket structure for being rolled in the sphere shaft portion side and top surface that swing ball axis outside, and the swing seat is in connection shaft
Position is groove structure；The oscillating rod is that one end is connected on swing ball axis, and the other end runs through the connecting rod at swing seat center
Part structure, the oscillating rod are connected through a screw thread with swing seat.
The beneficial effects of the utility model are: the structure is with good stability, guarantee the running precision of parallel machine,
And structure is simple, it is easy to use.
Detailed description of the invention
Attached drawing described herein is to be used to provide a further understanding of the present invention, and constitutes one of the application
Point, but do not constitute the restriction to the utility model.
Fig. 1 is Universal hinge structure front cross-sectional schematic diagram, and Fig. 2 is Universal hinge structure side profile schematic diagram.
Wherein: 1 is mounting seat, and 2 is swing ball axis, and 3 be bearing, and 4 be swing seat, and 5 be oscillating rod.
Specific embodiment
In conjunction with attached drawing, the utility model is described in further detail.
As shown, a kind of Universal hinge structure for parallel machine, includes mounting seat 1, swings ball axis 2, axis
Hold 3, swing seat 4, oscillating rod 5；The mounting seat 1 is concave base construction, is ball-and-socket shape in the middle part of the mounting seat 1, and
Two relative side is equipped with wall structure；Described 2 points of swing ball axis are two parts, are connection shaft and sphere axis respectively, wherein
Connection shaft is connected to the two relative side of sphere axis and is connect by bearing 3 with the wall of mounting seat 1, and sphere shaft portion
Then by with connect bearing 3 of the shaft in horizontal plane direction and be connected with swing seat 4；The swing seat 4 is to be rolled in swing outside
The sphere shaft portion side of ball axis 2 and the hollow ball socket structure of top surface, the swing seat 4 are groove structure in connection shaft position；
The oscillating rod 5 is that one end is connected on swing ball axis 2, and the other end runs through the connecting rod structure at 4 center of swing seat, the swing
Bar 5 is connected through a screw thread with swing seat 4.
When practical operation, oscillating rod 5 is supported on by needle bearing 3 and is swung on ball axis 2, and can be done around swing ball axis 2 ±
45 ° of swing；It swings ball axis 2 to be supported in mounting seat 1 by needle bearing 3, and ± 90 ° of pendulum can be done around mounting seat 1
It is dynamic；Connection with external rod piece and platform is completed by the screw thread of upper end and the mounting seat screw of lower end.
