Abstract

The invention discloses a crank shaft key groove width detection device, which is structurally characterized in that a transverse servo slipway is arranged on a fixing mounting frame via a connection plate, one end of the transverse servo slipway is connected with a motor fixing plate, and the motor fixing plate is connected with a servo motor; the other end of the transverse servo slipway is provided with a vertical servo slipway, one end of the vertical servo slipway is connected with the motor fixing plate, and the motor fixing plate is connected with the servo motor; the vertical servo slipway is provided with a measurement head fixing plate, and the measurement head fixing plate and the vertical movement slipway are connected via a screw; the measurement head fixing plate is provided with a measurement assembly; a drag chain sheet metal groove is arranged at the side of the transverse servo slipway and the vertical servo slipway, one end of the drag chain is fixedly arranged in the drag chain sheet metal groove, and the other end of the drag chain is connected with a drag chain fixing sheet metal. The crank shaft key groove width detection device has the advantages that by adopting automatic detection, the key groove detection speed and the precision are greatly improved; and by adopting an online detection mode, functions of autonomous perception, quality statistics and the like are realized, and the product quality information can be fed back timely.

Description

technical field [0001] The invention is suitable for detecting the width of a crankshaft detection keyway, belongs to the technical field of crankshaft detection, and in particular relates to a detection device for the width of a crankshaft keyway. Background technique [0002] The structure of the engine crankshaft is complex, and the processing quality of the crankshaft is directly related to the reliability, service life, vibration and noise of the automobile engine. In the manufacturing process, it is necessary to accurately measure and control multiple dimensions and geometric tolerances, including length, angle, shape and position, etc., such as the diameter of the main shaft and connecting rod shaft, the width of the journal, roundness, cylindricity, space phase angle , Coaxiality between the main shafts, etc. At present, keyway plug gauges are usually used to detect the keyway width of crankshafts. Using keyway plug gauges can only determine whether the keyway width...
