Abstract

PURPOSE: To facilitate trimming with a cutter, using a device for clamping a work to a table, by automatically tilting rearward a clamping piece in the path of the cutter as the cutter approaches.
CONSTITUTION: An end of a work (W) is clamped on a table 10 by means of a clamping piece 19. If the clamping piece 19 is in the path of a cutter 8, an air cylinder 18 is actuated to extend a piston rod 181, as the cutter 8 advances and light beams from a phototube 20 are received by a photosensing plate on the clamping piece 19. As the rod 181 is extended, a piston 15 rises due to the compressive force of a spring 14 and an arm 17 also rises. As the arm 17 rises, the clamping piece 19 releases its clamping force and the arm 17 inclines rearward to allow the cutter 8 to advance safely. A reversing valve of the cylinder 18 is actuated after a preset time to retract the rod 181 and the arm 17 is reset for clamping the work (W).
