Abstract

The invention discloses a limiting device used during chamfering machining of crankshaft oil holes. The limiting device comprises a fixing base, wherein a dividing plate is fixedly arranged on the fixing base, and 360-degree scale lines are arranged on the dividing plate, and the dividing plate is connected with a fixing plate through bolts; and on one side of the fixing plate is provided with a first fixing module used for fixing a shaft head end of a crankshaft, and the other side of the fixing plate is provided with a second fixing module used for fixing a flange end of the crankshaft. According to the limiting device, the crankshaft is limited, so that the oil holes in different positions and different directions of the crankshaft can be conveniently chamfered, and the defects that in an existing crankshaft oil hole chamfering machining process, the multiple times of limiting on the crankshaft are required to be carried out on a plurality of machine tools correspondingly, so that the plurality of machine tools are occupied, the production rhythm is low, and the labor efficiency is low are overcame; and the limiting device can limit the crankshaft for multiple times, the plurality of machine tools are not needed, the labor intensity of workers is reduced, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a limiting device for chamfering an oil hole of a crankshaft. Background technique [0002] The crankshaft oil hole is an integral part of the lubricating oil channel on the crankshaft. After the oil hole is drilled, in order to prevent the burrs at the end from scratching the engine, it is necessary to chamfer the end. Because there are many oil holes in the crankshaft and these oil holes are distributed In different positions and directions, it is difficult to chamfer them with existing equipment. In the prior art, usually a drilling machine only has one limit processing, and if multiple limit operations are to be performed, the processing must be performed separately on multiple machine tools. If multiple machine tools are used to process the chamfers of the straight and inclined oil holes of the crankshaft at different positions. The number of clampings wil...
