PURPOSE:To permit the working by easily correcting the warp even if the warp is at any position on a frame member by allowing a frame-member pushing plate at the center to automatically stop at the floated-up part of the frame member by an approach switch. CONSTITUTION:Over a frame member 1, the upper and lower guide rods 4 and 5 as linear slide base are installed, extending in the longitudinal direction of the frame member 1. A movable board 10 is installed in shiftable ways onto the guide rods 4 and 5. Further, an approach switch 14 which forms a floating-up detecting apparatus, is installed, projecting downwardly onto the undersurface of the movable board 10, and when the interval between said approach switch 14 and the frame body 1 reduces, the movable board 10 is stopped. When the movable base 10 stops, the piston rods 6a, 7a, and 13a of the cylinders 6, 7, and 13 extend at the same time, and the both edges of the frame member 1 and the floated-up part are pressed towards a clamping board 2 by pushing plates 8, 9, and 15. |
