A boring device for mating crankshafts

Abstract

This utility model relates to the field of machining technology, and in particular to a boring device for mating crankshafts, comprising a machine body with an external clamping frame for being held by a lathe tool post, the clamping frame being overhanging; a transmission device located inside the machine body, including a bushing and a bevel gear meshing transmission mechanism, the bevel gear meshing transmission mechanism including a driving bevel gear and a driven bevel gear, the driven bevel gear being sleeved and fixed on the bushing, the rotation axis of the driving bevel gear, the axis of the bushing, and the overhanging direction of the clamping frame being perpendicular to each other; the driving bevel gear is equipped with a drive; a boring bar is inserted into the bushing and connected to it by a key; the boring device of this utility model has a clamping frame for being held by the lathe tool post, which drives the boring bar to feed when the lathe tool post is laterally fed; the drive is arranged perpendicular to the axis of the mating boring hole and is rotated by a 90° transmission through the bevel gear, driving the bushing and the boring bar mounted thereon to rotate; with the lateral feed of the lathe tool post and the cooperation of the drive and transmission device, the mating boring machining is realized.
