Abstract
A tightening device for positioning a worktable of a machine tool to a base includes a saddle member disposed on the base, and a positioning carrier member carrying the worktable and movable relative to an abutment wall of the saddle member. An elongate adjusting member has a force-delivering end spaced apart from the abutment wall, and a middle threaded segment threadedly engaged with the positioning carrier member such that the force-delivering end is movable towards or away from the abutment wall. A force transmitting member is loosely connected to the positioning carrier member, and is configured such that a spiral force resulting from a screw-in movement is taken up by a proximate end thereof from the force-delivering end, and is transformed to a translation force that moves a distal end thereof to tightly engage the abutment wall.
