Abstract：According to the features of vibrating screen crankshaft, such as complex shape, low rigidity, large allowance, unbalanced mass distribution, high processing precision and so on, a numerical control machining fixture was introduced. The design requirements for crankshaft were put forward and working principles were described. Comparing with traditional processing technology, the new fixture fully considered the demands of generality, practicality, simplification and popularization, which has the distinct advantages of simple structure, low cost and batch production once without changing programming original point. The aims are to ensure the stability of positioning accuracy, improve the processing efficiency of crankshaft and bring advantages of numerical control machining into full play.
