Manipulátor pro automatickou výmenu nástroju je uložený ve skríni (1) opatrené odnímatelným víkem (2), jehož vnitrní mechanismus je vyveden vne jednak pro spražení s hnací jednotkou (3) a jednak pro spražení s manipulacním ramenem (4), uzpusobeným pro zajištení výmenného uchycení nástroju. Vnitrní mechanismus manipulátoru sestává z vacky (5), která je upevnena na rotacní vackové hrídeli (6) vyvedené vne skríne (1) a která je opatrena radiální vodicí drážkou (51), v níž jsou suvne uloženy vodicí kladka (7) rotace a vodicí kladka (8) translace, které jsou pres konstrukcní uzel (9) rotace a uzel (10) translace spraženy s hlavní hrídelí (11), na jejímž volném konci vyvedeném vne skríne (1) je suvne uloženo manipulacní rameno (4), pricemž vodicí kladka (7) rotace a vodicí kladka (8) translace jsou umísteny v rovinách procházejících podélnou osou vacky (5), které jsou vzájemne pootoceny o 90.degree.. The present invention relates to a manipulator for automatic change of tools being mounted within a housing (1) provided with a removable cover (2) and having its internal mechanism lead outside for both coupling with a driving unit (3) and for coupling with a handling arm (4) adapted for securing an exchangeable mount of the tools. The manipulator internal mechanism consists of a cam (5), being attached to a rotating camshaft (6) lead out of the housing (1) and being provided with a radial guide groove (51) serving for slidably mounting therein a rotation guide roller (7) and a translation guide roller (8), which are coupled via a rotation structural center (9) and a translation structural center (10) with a main shaft (11) wherein the handling arm (4) is slidably mounted on the main shaft (11) free end being lead out of the housing (1). The invention is characterized in that said rotation guide roller (7) and said translation guide roller (8) are situated in planes passing through the longitudinal axis of the cam (5) and being angularly displaced relative to each other by 90 degrees.
