The technical scheme that solves the problems of the technologies described above is:
A kind of saw blade inside and outside circle finish turning positioner; It is made up of centring sleeve and centration axis, and centring sleeve is a steel sleeve, and centration axis is the steel circular shaft; The internal diameter of centring sleeve and the external diameter of centration axis are complementary; Vertical lathe meets disk center has through hole, and centring sleeve is embedded in the through hole, on the upper and lower end face of centration axis the screw perpendicular to the centration axis axis is arranged.
Above-mentioned saw blade inside and outside circle finish turning positioner, the external diameter of said centration axis is less than the aperture of the undressed centre bore of processed saw blade.
Above-mentioned saw blade inside and outside circle finish turning positioner, the lower end of said centring sleeve is a taper hole, and there is tapering the lower end of centration axis, and centration axis lower end tapering and centring sleeve lower end taper hole are complementary.
The usefulness of the utility model is:
The saw blade inside and outside circle finish turning positioner of the utility model is on existing frock basis, to innovate; A steel centring sleeve that has taper hole is inlayed at the center that connects dish at cast iron; The centration axis that has centre bore can import wherein self-centering accurately; Use the bolt that passes the centration axis center that it is fastened on then and connect on the dish, only need on lathe, once just can relatedly use by centering before using.This device adds saw blade and feels relieved centering man-hour fast, accurately, guaranteed the machining accuracy of saw blade, has solved a long-term unsolved difficult problem with very simple improvement, has obtained very good effect, is worth applying in the machined field.
Description of drawings
