End rotation connection;All rotary shafts are parallel to each other and horizontally disposed;The first movement branched chain in two movement branched chains
In addition to no second expansion link and its connector, annexation and the second movement branched chain phase between other parts and part
Together;On the moving platform, by the driving of three expansion links of three movement branched chains, it is flat that motion can be achieved in workpiece or fixture installation
Two-dimensional movement of the platform in vertical plane and the rotation around a trunnion axis.
The present invention has the following advantages that compared with prior art:
1st, there is clear and definite kinetic characteristic, i.e. the two-dimensional movement in vertical plane and the rotation around a trunnion axis.
2nd, kinematics of mechanism algorithm is simple, precision is high, bearing capacity is strong, simple in construction, moving range and upset ability are big
And good manufacturability.
3rd, the present invention has wide practical use in modern industry field, is particularly suitable for linking with welding robot, is used for
The welding of large complicated part.
