Abstract

The invention provides a machining die and a machining method for a taper key groove of a taper hole, and relates to the technical field of machining. The machining die for the taper key groove of the taper hole comprises a fixed base (1), a positioning core (2), an adjusting nut (3) and a check ring (4); the fixed base (1) is provided with a boss (102), a plurality of mounting holes I (101) and a cutter passing groove I (103); and the positioning core (2) comprises a machining section (201), a positioning section (202), a threaded section (203), a mounting section (204), a plurality of mounting holes II (205) and a cutter passing groove II (206) obliquely penetrating through the positioning core (2). The machining method comprises the steps of machining die fixing, to-be-machined workpiece positioning and fixing and broaching machining. The technical problems that the taper hole inner key groove machining precision is poor and efficiency is low are solved, and the machining method is high in efficiency and suitable for machining of large-batch products.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a processing mold and a processing method for a tapered hole and a tapered keyway. Background technique [0002] Because the generatrix of the taper hole is not parallel to the center line of the hole, it is much more difficult to process the keyway in the taper hole than in the straight hole. Especially, when the keyway is parallel to the generatrix of the taper hole, the machining difficulty is even greater. The common processing methods for the keyway in the taper hole are: wire cutting and slotting machine. When wire cutting is used, the angle of the molybdenum wire needs to be adjusted to be parallel to the taper hole busbar, which is difficult to debug. When using slotting machine, it is necessary to make a bevel Tooling, so that the generatrix of the taper hole is parallel to the movement track of the inserting knife; these two methods are inefficient and not...
