Abstract

The invention discloses a detection device for an engine crankshaft. The detection device comprises a detection platform and a detection component, wherein the detection platform is equipped with a mounting bracket for mounting a crankshaft; a rotating rod is arranged in the detection platform; the rotating rod is equipped with a plurality of discs spirally arranged at equal intervals along the axial direction; each disc is connected with a crankshaft journal of the crankshaft through a connecting component; and one side of the detection platform is also provided with a driving component connected with the rotating rod. The detection device is compact in structure, and reasonable in design. Through use of the device to detect the engine crankshaft, the simulation of a crankshaft working environment can be realized, the change in the crankshaft working state can be reflected, the accuracy of crankshaft detection can be improved, and the quality of the crankshaft can be controlled. The detection device has the characteristics of convenience in operation and high practicability.

Description

technical field [0001] The invention relates to the technical field of detection of engine components, more specifically, it relates to a detection device for an engine crankshaft. Background technique [0002] The crankshaft is the most important part of the engine. It bears the force transmitted by the connecting rod and converts it into torque to drive other accessories on the engine through the output end of the crankshaft. During the working process, the crankshaft is subjected to the combined action of the centrifugal force of the rotating mass, the periodically changing gas inertial force and the reciprocating inertial force, so that the crankshaft is subjected to bending and torsional loads. Therefore, in the process of crankshaft design and production, it is necessary to test the crankshaft to grasp the quality of the crankshaft. At this stage, the detection of the crankshaft is mostly based on the size, assembly angle and sealing, which cannot effectively reflect ...
