Description
Technical Field
The utility model belongs to the technical field of automobile engine technique and specifically relates to a coplanarity measuring device of engine train is related to.
Background
The flatness detection tool is a tool for detecting flatness or detecting whether two planes are parallel and coplanar. Abnormal noise of an engine belt occurs when an automobile is used, wherein the abnormal noise is mainly caused by poor coplanarity of engine gear trains. And the problem of uneven wheel surfaces cannot be avoided in the actual production and assembly of the engine, so that a flatness detection tool is required to be used for accurate measurement, manual judgment is assisted, a method is adjusted in time, and deviation is corrected. At present, most of the existing plane detection tools mainly use laser and test probes, are expensive, complex in structure and inconvenient in operation space, and cannot adapt to the narrower measuring environment of the engine gear train measurement. How to effectively measure the deviation degree of two planes with low cost and accuracy is a problem to be solved urgently at present.
