Multi-spindle drilling machine having exchangeable spindle head

Abstract

Abstract PURPOSE:To improve efficiency of drilling work, by movably providing a plurality of spindle heads to the peripheral surface of a cylindrical unit, connecting the optical spindle head to a driving gear at a drilling position and promptly and adequately preparing the next drilling tool. CONSTITUTION:A cylindrical guide rail C is fixed to a strut 4, and a cylindrical conveyer unit D, provided with a plurality of exchange spindle heads B in the peripheral surface, is turnably provided on said rail. A drilling position C1 of said rail C and a mounting part of the spindle head B of said conveyer unit D are vertically movably and slidably divided in the axial direction. Further a driving gear A is vertically slidably mounted to a drilling position of the strut 4 through a track guide device E, and the driving gear A and the spindle head B are connectable through clutches 2, 9, further integrally formable by a piston rod 13 and circular arc grooves 23, 24.
