PURPOSE:To permit an object to be correctly mounted to and removed from a base, by fixing the base to a predetermined position by the first signal while holding the base in a floating condition by the second signal. CONSTITUTION:If each stopper adjusting screw 29 of a positioning clamping mechanism 16 and a clamping mechanism 17 is adapted to a stopper 30, a vibro-isolating base 12 is both positioned in its direction Z and clamped to a fixed bed 11. In this way, if the vibro-isolating base 12 reaches a fixed position, a sensor generates a clamp completion signal, and a device, advancing to the next step, performs removal and mounting of a workpiece. When the work is finished, an automatic hand action end signal is generated from an equipment 5, and a pull rod 31 is lifted. Accordingly, the vibro isolating base 12, being freed, is lifted to the upper by force of an air spring 4 and released from a clamped condition. |
