Abstract
PURPOSE:To position and fix a large work efficiently and exactly by mounting at least one pair of hydraulic cylinders which press the opposing side faces of the work facing in one direction and another perpendicular thereto and providing a plural-cylinder synchronizing oil pressure supply device for each of the cylinders. CONSTITUTION:A work W is transferred into an area surrounded by primary hydraulic cylinders 3 and 3 and secondary hydraulic cylinders 4 and 4 on a base member 5 and primary and secondary plural-cylinder synchronizing oil pressure supplying devices 31 and 32 started. The pressure operating chamber of the pressure increasing part in the since supply devices 31 and 32 are connected to each of the primary and secondary hydraulic cylinders 3 and 4 respectively, the pistons in those pressure operating chambers are driven synchronously by the driving parts. When the driving parts are driven, oil at the same pressure is transmitted at the same flow rate to the primary hydraulic cylinders 3 and similarly, to the secondary hydraulic cylinders 4. The work W is moved to the middle point of the area surrounded by the primary cylinders 3 and the secondary cylinders 4, positioned and fixed.
