Abstract

The invention discloses a machining method of an inner hole key groove, and belongs to the field of machining. According to the machining method of the inner hole key groove, a to-be-machined workpiece with the inner hole precision and the end face planeness and parallelism meeting preset values is provided, milling machining of the length of the key groove is completed in two times through face adjusting, before the two times of milling machining, the position of the to-be-machined workpiece is adjusted based on an inner hole and end faces, and the axis of the inner hole is parallel to a spindle of a boring machine. The coaxiality of the axis of the inner hole and the spindle of the boring machine can be improved easily, then the machining precision of the inner hole key groove is improved, meanwhile, the stroke machining workload can be reduced, and the machining efficiency can be improved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a method for processing an inner hole keyway. Background technique [0002] The inner hole keyway is a groove machined on the inner hole of the workpiece, which is used to fit with the corresponding key to transmit torque. During the machining of the keyway in the inner hole, the workpiece does not move, and the spindle of the boring machine drives the tool to move axially on the inner hole to bore out the keyway. For the keyway whose length is longer than the spindle stroke of the boring machine, it is difficult to form the keyway in one cut. It is necessary to process a section of keyway first, and then process another section of keyway until the two sections of keyway are connected. However, after surface adjustment, when recalibrating the workpiece position, the axis of the inner hole before adjustment cannot be guaranteed to be consistent with the axis of the inner hole...
