Abstract
The utility model discloses a high-precision gear ring support finish turning tool which comprises pressing caps, hole check rings, elastic expansion sleeves with teeth and taper bodies. One sides of the hole check rings are installed at the two ends of the pressing cap respectively, and the other sides of the hole check rings are connected with the elastic expansion sleeves with the teeth. Workpieces are installed in the middles of the pressing caps, and the taper bodies are installed between the workpieces and the hole check rings. The high-precision gear ring support finish turning tool facilitates installation of the workpieces, and is high in positioning precision and capable of effectively overcoming the defect that the positioning precision of a spline mandrel is poor.
