Abstract

Instalatia hidraulica de actionare pentru prinderea semifabricatelor pe masini-unelte conform inventiei, se compune dintr-un grup de pompare a instalatiei de ungere a masinii-unelte, care furnizeaza lichid sub presiune unui hidromotor de joasa turatie, acest hidromotor putând fi rotit în ambele sensuri si blocat cu ajutorul unui distribuitor cu trei pozitii, si putându-i-se regla turatia cu ajutorul unor drosele cu supape de blocare, limitarea fortei de strângere a semifabricatului facându-se cu ajutorul unui releu de presiune, iar limitarea cursei bacurilor la desfacerea mandrinei de strângere facându-se cu ajutorul unui releu de timp.The hydraulic drive device for clamping the semifinished machine tools according to the invention consists of a pump unit of the machine-tool lubrication system which supplies pressure fluid to a low-speed hydro-motor, this hydromotor can be rotated in both directions and locked by means of a three-position distributor, and it can be adjusted by means of a drop of locking valves, the limitation of the tightening force of the blank being made by means of a pressure relay, and the limitation of the stroke of the jaws tightening is done using a time relay.
