Abstract
A fixture for turning and polishing wheel hubs relates to the technical field of wheel hub manufacture. A plurality of insertion tenons are annularly arranged around a central hole of a positioning base on a cylindrical member of a central positioning base. The central positioning base is coaxially fixed with a disc-shaped fixing base through screws. Six positioning blocks are annularly arranged on the fixing base around the circle center of the fixing base in an array manner. The positioning blocks are fixed on the fixing base through screws. A positioning slot is molded on each positioning block. The upper part of a technological platform of a wheel hub blank is inserted into the positioning slots. The insertion tenons are inserted into recesses of the wheel hub blank. Spinning cylinders are fixed below the fixed base through screws. The piston rod of each spinning cylinder extends out of the upper surface of the fixed base. An L-shaped pressing block is fixed on the piston rod of each spinning cylinder. The pressing blocks press the technological platform. The fixture provided by the utility model has functions of: positioning the wheel hub blank with higher accuracy, improving machining uniformity and precision, realizing higher clamping firmness for the wheel hub blank, and obtaining high smoothness in chip discharging.
