【Abstract】 The position counterchange method of rigid body is introduced, an inductive mechanism to realize straight track is designed by using this method, and a practical formula to check extreme position is also proposed. A double-rocker inductive mechanism designed by using this method can meet the needs for straight displacement motion within a large extent presented by a tube flattening machine.更多还原
