Abstract
PURPOSE: To adjust an oil hydraulic cylinder simply by a method wherein, in such an oil hydraulic cylinder for use in a machine tool that its low speed operating range can readily be adjusted, the length of a shaft portion protruded from the end surface of the piston is adjusted.
CONSTITUTION: If pressure oil is sent from a port A, a piston 3 is moved to the left in a cylinder 2 at relatively high speed, and the pressure oil in a chamber C is discharged from a port D through pressure oil passage 9, 11. Next, if the end of a shaft 7 which moves together with the piston 3 is fitted into the opening 9a of the pressure oil passage 9 to block up the opening, the pressure oil in the chamber C is discharged from the port D only via the passage 11, thereafter the piston 3 is moved at low speed. Therefore, the adjustment of the length of the protruded shaft 7 portion made by the operation of a knob 8 allows to readily obtain the desired lengths of high and low speed operating strokes.
