The invention discloses a powerful tooth scraping machining method used for a universal tooth inserting tool. A numerical control machine tool with a six-axis four-linkage function is adopted. The method includes the steps that a spindle cutter of the numerical control machine tool is installed on a shaft B; a workpiece is installed on a rotary table; a certain center distance and a certain installation angle exist on the center line of the spindle cutter relative to the center line of the workpiece; the workpiece is installed by calculating the additional small compensation amount of the installation center distance and the installation angle of the spindle cutter, and a numerical control system of the numerical control machine tool is controlled for machining parts; the cutter conducts feeding movement in the axial direction of the workpiece, after one-time cutting is completed, the cutter retreats to the initial feeding position, then, the cutter conducts feeding movement in the radial direction of the workpiece, and the movement process is repeated until machining of the whole workpiece is completed. The universal tooth inserting tool is adopted as the tool, batched customizing is convenient, and compared with designing and manufacturing of existing tools special for tooth scraping machining, the tool use cost of a numerical control powerful tooth scraping machining device is reduced.
Description
technical field [0001] The invention relates to a powerful gear-shaving processing method, in particular to a powerful gear-shaving processing method based on a universal gear shaping tool, and belongs to the technical field of mechanical gears and processing equipment. Background technique [0002] With the development of gear cutting processing technology towards high precision, high efficiency, and environmental protection, it is urgent to research and develop new processes and technologies for gear processing. As a new concept of gear cutting processing, power skiving processing has higher production efficiency than hobbing and gear shaping processing, especially for small modulus internal gear processing, which can generally improve compared with hobbing and gear shaping processing methods. More than 4 times, the machining accuracy can also be improved by 1-2 grades. A powerful gear skiving processing method based on a universal gear shaping tool specifically refers to...
