Abstract:
A clamping and positioning mechanism for the inclined axis of two-axes rotary tables, said work table having a revolving body mounted on a stationary supporting frame, said revolving body comprising a revolving arm on which a work is carried, and an inclined axis on which said revolving arm is mounted, said inclined axis being sustained by an axle bush which being tightly engaged to said stationary supporting frame, and can be turned to a position with a predetermined inclination angle by a transmission means, and held thereat by means of said clamping and positioning mechanism which comprising:an annular recessed slot formed along the outer surface of said stationary supporting frame facing said axle bush;a totally cross sectional piston installed in said annular recessed slot and normally located at a relaxed position away from said axle bush by an elastic force of a spring;at least one connecting rod connected to said piston and extended to an inner surface of said stationary supporting frame facing to said axle bush;at least one double diameter hole bored through said axle bush and having a vertical end surface;at least one double diameter brake member passing through said double diameter hole and being connected to said connecting rod; andan oil pressure supply means capable of removing said piston from said relaxed position to a braking position, said piston being displaced to said braking position simultaneously carrying said double diameter brake member to forcibly press against said vertical end surface of the double diameter hole so as to make said axle bush further tightly pressing on said stationary supporting frame thereby positioning said inclined axis at a position with a predetermined inclination angle.
