Abstract

See full text

Disclosed is a cam curve design method for a cap screwing machine based on a multi-objective method, belonging to the technical field of cap screwing machine cam design. The present disclosure is to solve the problem that the conventional method for redesigning the cam curve cannot optimize the parameters according to the degree of importance such that the operating stability of a cam mechanism is poor. The method comprises: acquiring key point data determined for realizing the functions of a cam of the cap screwing machine; performing dimensionless processing on the key point data to obtain a dimensionless time T and a dimensionless displacement S; writing an n-order polynomial fitting cam curve displacement function, manually interpolating local control points, and obtaining a polynomial fitting cam curve expression and chart in combination with the constraints of key point displacement by using a least squares method; and selecting cam curve optimization objectives and setting weight coefficients to construct an optimized cam curve. The present disclosure is used for the design of a cam curve.
