BLADE AND MOTOR CARRIER WITH HEIGHT/ANGLE ADJUSTMENT MECHANISM

摘要

A machine tool has a work table which defines a working surface and has a cutting tool which is attached to and movable with respect to the work table. Th e position of the cutting tool with respect to the working surface is controlled b y a mechanism which elevates the cutting tool with respect to the working surface an d angulates the cutting tool with respect to the working surface. The cutting tool is mounted to a support plate which is pivotably attached to the work table. The elevating mechanism includes a threaded rod and a nut which engages a pivoting link. The pivoting link also engages the cutting tool. Rotation of the threaded rod pivots the link which in turn raises and lowers the cutting tool. A spring biase s the cutting tool towards its lower position to remove play between the components. T he angulating mechanism includes a lever, two cams and a locking rod. Rotation of t he lever moves the locking rod longitudinally due to the action between the two cam s. The longitudinal movement of the rod compresses the support plate between the wo rk table and a bracket to maintain the position of the support plate with respect t o the work table. Also included is an integral arbor wrench which is accessible when t he throat plate is removed to lock the arbor to facilitate tool changing. The wrenc h is designed to not allow reassembling of the throat plate when the wrench is in engagement with the arbor shaft.
