<p>PROBLEM TO BE SOLVED: To reduce the number of machining processes in a trimming process, to dispense with a fluid cylinder and the like so as to accomplish reduction in the number of parts and compactification, and to install a workpiece holding jig in a suitable position in a trimming device. SOLUTION: Workpiece pressing arms 19, 27 provided with counter weights 20, 29 individually are unclamped if a tilting base 12 is positioned in a tilting position P2 by means of the weight of the counter weights 20, 29, while the workpiece pressing arms 19, 27 are clamped so as to press a workpiece 100 to a workpiece receiving base 14 if the tilting base 12 is positioned in a horizontal position P1 . In this way, the workpiece 100 is clamped/unclamped only by tilting the tilting base 12 between the horizontal position P1 and the tilting position P2 .</p> |
