1. spherical pad spherical outside surface clamp, the spherical pad of institute'"'"'s grinding diametrically arranges a narrow connected in star on spherical outside surface, it is characterized in that:

  • described fixture comprises the clamp body with spherical outside surface and the concrete ring flange of geometrical clamp, the spherical outside surface radian of clamp body is identical with the Internal Spherical Surface radian of spherical pad, the top circumference of clamp body spherical outside surface is laid with multiple alignment pin, the center line of alignment pin and the rotation centerline of clamp body intersect vertically, the external diameter of alignment pin and the diameter of bore of spherical pad match, the top of alignment pin is provided with the transverse groove corresponding with narrow connected in star, the setting direction of transverse groove is the top circumference direction of clamp body spherical outside surface, during grinding work, the spherical pad be arranged on clamp body spherical outside surface carries out Internal hole positioning by alignment pin and carries out tighten by band rope, the winding of band rope forms a circle on clamp body spherical outside surface, band rope is through narrow connected in star and transverse groove, band rope is highly less than the narrow connected in star degree of depth, the end face outside of clamp body is fixedly connected with end cap, the end face outside of end cap arranges rotor plate, be connected by lock-screw between rotor plate with end cap, lock-screw activity is connected on end cap through the centre bore rear thread of rotor plate, band rope two ends enter into clamp body endoporus through clamp body spherical outside surface, then be connected on rotor plate through end cap.
