MACHINE TOOL HAVING A ROTARY WORKTABLE |
摘要 |
A machine tool having a rotary work-table driven in rotation by a circular gear carried by the work-table cooperating with a worm gear and drive mechanism mounted on the work-table support. The underside of the work-table bears upon a slideway. The work-table is locked to the slideway by means of three equidistant posts biased into clamping relationship with a slot in the slideway. An annular piston operates a linkage that engages the posts, and upon actuation of the piston the posts are moved to a position spaced from the slot to unlock the work-table for rotation. The annular piston also moves a plurality of bearings into engagement with the underside of the work-table to remove the full load thereof from the slideway to facilitate rotation.
