Assembly to move and position a machine tool has a structure of four linkages at the carrier to define a carrier swing axis, in a simple and stiff structure to increase the machine tool movements

摘要

The assembly to move and position a machine tool has a base (B) and especially a slide frame. It gives movement on a number of axes for a carrier (1), with four linkages (G1-G4), each with at least two rotary degrees of freedom. They are mounted in opposing pairs at the carrier, to define a carrier swing axis (TS1,TS2). The linkages can each slide to the base. The carrier swing axes have a common intersection point, and each linkage is equidistant from the intersection.
