More Information
Summary:The utility model provides a taper hole centering is expanded and is overlapped, including the cover body that expands, expand the cover body for hollow cone shape structure, central through -hole is the taper hole, the cover lateral wall that expands is equipped with the recess that a plurality of axials distribute, recess projection on the lateral wall is the curve, be equipped with the rubber strip in the recess. A taper hole centering is expanded and is overlapped structural design equitable, the smooth inflation of the cover that guarantee to expand will be waited to process the work piece and press from both sides tightly, realize the axle center location, not unidimensional product just can be produced to the bloated cover of the different models that only need to be changed in the actual production, has both saved the cost that tooling design made, can lengthen the frock life -span again, reduces the frock wearing and tearing, improves positioning accuracy, the grade of precision of promotion converte
