The invention discloses a method for processing key grooves of a shaft, which comprises the following steps that: two V-shaped iron blocks are fixed on a worktable of the common milling machine; a workpiece shaft to be processed is put into V-shaped grooves of the two V-shaped iron blocks; a connecting disc is arranged on one end face of the workpiece shaft to be processed, and an alignment block is fixed with the connecting disc, so that two alignment surfaces of the alignment block are vertical or parallel to the radius direction of the key grooves to be processed; the workpiece shaft and the alignment block are aligned, and the workpiece shaft and the two V-shaped iron blocks are pressed on the worktable by pressing plate bolts and pressing plates; and the key grooves on the same bus are processed by an end milling cutter in rough and fine modes, a workpiece is rotated 90 or 180 degrees, and the processes are repeated so as to process the key grooves on a plurality of buses of the workpiece shaft. By the method, the form and position tolerance of a product is ensured, a few parts are used, the structure is simple, and the workpiece is conveniently, quickly, safely and reliably clamped.
Description
technical field [0001] The invention belongs to the technical field of mechanical processing and manufacturing, and relates to a processing method for shaft key grooves. Background technique [0002] The shaft is one of the most common parts for mechanical transmission and connection. There are often multiple keyways distributed on the same busbar on different circumferences on the shaft. Most of the products are most commonly distributed at 90° and 180°. Generally, manual marking is used. Methods It is difficult to guarantee the positional accuracy requirements of each keyway when machining keyways on ordinary machine tools. Contents of the invention [0003] The purpose of the present invention is to provide a method for machining shaft keyways, which solves the problem that in the prior art, manual scribing is used to process keyways on ordinary machine tools, and it is difficult to ensure the position accuracy of each keyway. [0004] The technical solution adopted in...
