摘要：

By using theoretical modeling, simulation and experiment, the static clamping force characteristics was studied in terms of the operation parameter, structural parameter, lubrication conditions, and strength of the wedge type power chuck. The investigation performed showed that friction, especially the friction taking place on the contact surface between the wedge actuator and base jaw, is a great influence on the magnitude of static clamping force. Before the twice clamping a workpiece using a chuck, it is suggested to operate the chuck with thrice virtual travel to reduce the deterioration of lubrication condition. The chuck structure which has a higher clamping efficiency will have a fewer static clamping force loss caused by the enlargement of friction. With comprehensive consideration of magnitude and stability of static clamping force, the wedge angle of chuck should be selected from 10° to 20°. The maximum static clamping force is limited by the strength of chuck, especially by the strength of wedge type teeth of base jaw. ©, 2015, Editorial Department of Journal of Sichuan University.
