    摘要: A drill press assembly having a base mountable to a work bench, a vertical column attached to the base and a drill head assembly having an electric motor and a quill. The drill head assembly is movably attached to the column. A rack is rotatably attached to the top of the column and is engaged by a crank and pinion mechanism attached to the frame of the drill head assembly which permits the drill head assembly to be displaced vertically and rotated about the column. A tilt table is attachable to the base of the drill press. A locking mechanism having a bolt passing through a longitudinal slot in the supporting base of the tilt table and a transverse slot in the base is engaged by an eccentrically mounted camshaft to lock the supporting base of the tilt table to the top surface of the drill press base. A pivoting frame is pivotably attached to the supporting base and contains a table plate. A fence is attachable to the top of the pivoting frame. The fence has a stopping block to facilitate the location of a workpiece on the tilt table. A work clamp is also provided on the drill head assembly to clamp a workpiece on the tilt table.

    摘要: A saw blade position setting apparatus of a working table such as a table saw which is mounted on a support frame and to which a blade assembly is mounted with a handle assembly including a handle and a handle shaft held by the support frame to be rotatable and operatively connected to the blade assembly. The blade assembly is supported by a support member connected to the handle shaft. A clutch mechanism is selectively transmitting rotation of the handle to a blade assembly elevating mechanism and a blade assembly inclining mechanism. The elevational position and the inclination of the blade assembly are adjusted in accordance with the rotation of the handle assembly. A rack is secured to the support frame and the handle assembly is moved along the rack to a predetermined angle position. A lock lever is disposed in operative association with the handle assembly and operatively connected to the clutch mechanism. The lock lever serves to lock the support member to the predetermined angle position and is provided with a cam mechanism through which operation of the clutch mechanism is changed.

    摘要: A variable cutting-angle circular saw device includes a base; a rotary table 2 rotatably disposed in the central portion of the base; a bracket liftably attached to a hinge; a motor, a speed reducer, a circular saw, an outer cover, and a safety cover, all being fixed to the bracket; a fence fixed in a rearward position of the base; a clamp fixed at left- and right-hand positions of the device so as to allow a workpiece to be clamped for cutting the workpiece. A sawdust-guiding frame piece is suspended from a lower end of a rear portion of the cover so as to smoothly block a gap between the lower end of the rear portion of the outer cover and an upper surface of a curved portion in the central portion of the fence, guiding the sawdust blowing up via the blow-up port, to the inner side of the rear end of the outer cover. A sawdust accommodating chamber below the rotary table is closed at the bottom and has a substantially arcuate bag-like shape, and communication with the cover via a port at the rear thereof.
