Coupling halves joined by rocker supports and joints

摘要

One rocker support (4) per pair (3) adjusts in length depending on the tensile force (P2) and/or compressive forces (P1) until re-set to original length by a motorised device. The supports are allotted an auxiliary device to counteract this elongating force, with both forces (P1,P2) variable. The rocker should be made up of a free-riding threaded spindle running in a nut or as two powered cylinders and piston units arranged in series, one unit extensible and the other controllable. The motorised re-set devices are powered electrically or by compressed air, the two coupling halves (1,2) being joined by means of the two rocker pairs. The several rocker pairs join the coupling halves in a crossover layout or join these in a ring form when several pairs of rockers are involved, e.g. three pairs in all. All rockers are of pre-set average length and are used preferably in industrial robots.
