The utility model relates to the technical field of
ball screw, concretely is a kind of two-way thread double-
station ball screw, including
workbench, sliding element, installation element, first screw
assembly and second screw
assembly;Sliding element is set at the both sides of
workbench, first screw
assembly and second screw assembly are oppositely set on
workbench to drive the
relative motion of sliding element;The both ends of installation element are erected in workbench, the installation element is used to first screw assembly and second screw assembly installation, so that first screw assembly and second screw assembly carry out unified transmission on the workbench;By setting sliding element at the both sides of workbench, the
relative motion of first screw assembly and second screw assembly is provided with stable support and smooth sliding condition, by oppositely arranged first screw assembly and second screw assembly, the synchronous or asynchronous motion of double-
station can be realized, increase flexibility and functionality, satisfy different work needs, or carry out different operation to different workpieces, improve work efficiency, and it is strong practicality.
