摘要

The 3D geometric model was established based on working principle of a new keyway broaching machine. The horizontal deformation of drawing knife blade in working stroke is analyzed by the finite element software ABAQUS. The research which effect law of the feed, structural sizes of cutter rod and sizes of cutter guiding rod on position deformation of broaching blade in working stroke given quantitative relationship between parameters of processing craft and structure and cutting precision. The selection method and way of processing parameters and structural parameters to improve broaching precision of keyway broaching machine are obtained. The research work provides relevant technological basis for the design of high precision keyway broaching machine.
