Title: Clamping and positioning mechanism for the inclined axis of two-axes rotary tables

Abstract: Disclosed herein is a clamping and positioning mechanism for the inclined axis of two-axes rotary tables comprising an annular recessed slot formed along the outer surface of a stationary supporting frame. In this slot, there is installed a piston with a large cross sectional area and a plurality of connecting rods are in connection with the piston. These connecting rods are penetrated through corresponding plurality of respective through holes which are bored through the stationary supporting frame, and are extended until the surface of an axle bush of the inclined axis. There are plurality of double diameter holes opened on the axle bush so as to accept a plurality of double diameter brake members passing through those corresponding double diameter holes and screw combine with the extended ends of the connecting rods respectively. A spring is provided to regularly and elastically pressing against the piston such that the double diameter brake members are under relaxed position. As soon as an oil pressure is exerted from an oil pressure supply mechanism to actuate the piston, which in turn displaces each double diameter brake member to a braking position by way of the connecting rods, the axle bush of the inclined axis and the stationary supporting frame are thus forcibly pressed each other, and furthermore, the inclined axis together with the revolving axis sustained thereon is exactly positioned at a position with a predetermined inclination angle.
