ABSTRACT:
A clamping device for milling working of engine is provided which makes stability of working operation by stably fixing without trembling upon milling working of casted engine and improves a working preciseness and prevents deformation of members by dispersing excessive clamping force. The invention comprises: in a clamping device for milling working of engine including a base member, a sub-clamp which is fixed on the base member and supports bottom surface of cylinder block, and a main-clamp fixing by pressing vertically from upward a cylinder block supported by the sub-clamp; an oil pressure cylinder to be mounted to bottom or body's interior of said base member so that a piston rod is reciprocally moved in horizontal direction; a horizontally operating rod for slidably moving in horizontal direction by said piston rod; a vertically operating rod for rising in vertical direction by cooperatively moving therewith upon forwardly moving of said horizontally operating rod; and a push rod for fixing by applying a pressing power to a journal member of said cylinder block by slidably moving in horizontal direction upon rising of said horizontally operating rod by cooperatively moving therewith.
