Alignment device and method for machining strict phase-position key groove of gear inner hole

Abstract

The invention discloses an alignment device for machining a strict phase-position key groove of a gear inner hole. The alignment device is characterized in that two symmetrical installation holes are formed in the inner edge of the outer end of a locating plate along the center line, and a fixed pin is installed in each installation hole; long grooves are machined in the inner edge of the inner end of the locating plate along the center line, movable pins are movably arranged in the long grooves, and the moveable pin ends of the movable pins are hooked on the upper edges of the long grooves; a baffle in the perpendicular direction is fixedly installed on the inner end face of the locating plate, the baffle and the locating plate are buckled through a bolt, an abutting screw is installed in a screw hole formed in the position, corresponding to the center line of the locating plate, of the baffle, and the abutting screw is in contact with the movable pins in an abutting-against mode; an alignment face is machined on the locating plate. The invention further discloses an alignment method for machining the strict phase-position key groove of the gear inner hole. The alignment device and method are simple in structure, easy to operate and high in accuracy.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment manufacturing, and is used for processing the keyway with strict phase requirements on the inner hole of the gear and the specific tooth. Alignment method when machining the strict phase keyway of the inner hole of the gear. Background technique [0002] Gears are one of the most commonly used and important parts in mechanical equipment. Gears with hard or soft tooth surfaces are generally centered with the inner hole of the shaft, and various keys are used to achieve positioning and torque transmission, including various splines and tangential keys. And ordinary flat keys, etc., so the phase relationship between the key and a specific tooth of the gear will determine the phase relationship between the shaft and a specific tooth, thereby determining the phase relationship between the mechanical system and a specific tooth. For some gears, due to the limitation of the internal mechani...
