Abstract

PURPOSE: To surely prevent the snapping accident of cords and a short-circuit accident due to chips, cutting oil or the like, by housing switches for detecting the stoppage of a carriage, in the control box of a machine tool.
CONSTITUTION: A high pressure detection switch 28 and a zero pressure detection switch 30 are provided so that the closed position of the switch 28 is set at prescribed point on the upper limit of the moving region of an oil pressure detection moving member 26 and the switch 30 is placed in a prescribed position on the lower limit of return in the movement region of the moving member 26. A high pressure detection switch 44 placed in a prescribed position on the upper limit of the moving region of the second oil pressure detection moving member 42 and a zero pressure detection switch 46 placed in a prescribed position on the lower limit of return in the movement region of the second oil pressure detection moving member 42 are housed in a control box 52. Electric circuits are provided so that a signal indicating the turn-on of both switches 28, 46 is used as a detection signal of the stoppage of a carriage coupled to a piston rod 4 and a signal indicating the turn-on of both the switches 44, 30 is also used as a detection signal of the stoppage of the carriage.
