Device for machining contour and end face of special-shaped part

The invention discloses a device for machining the contour and the end face of a special-shaped part. The diameter of the outer circle of a mounting disc is the same as that of the outer circle of the part, and a circle of groove is formed in the upper end face of the mounting disc; eight height-adjustable locating supports are fixed to a circle of locating boss at the outer end of the groove; the inner and outer circles of locating blocks are arc-shaped, and the thickness is the depth of the groove; the inner edge is provided with an arc-shaped bulge of which the outer circle diameter is the same as the inner circle diameter of the part; the four locating blocks are fixed to the inner circle end of the groove of the mounting disc at the same circumferential interval; the inner ends of four pressing plates intersect at the outer circle of a center hole of the mounting disc, and the outer ends of the four pressing plates can be pressed on a machined part in a connected mode, and fixed to the upper end face of
