Abstract

The invention discloses an integrated detection device applied to a small aero engine crankshaft. A stationary center and a live center of the detection device are arranged at two ends of a base, and the stationary center and the live center are positioned with two ends of the crankshaft for clamping the crankshaft; two V-type blocks are fixed at the upper part of the base and located between the stationary center and the live center, and the supporting positions are at two main journals of the crankshaft respectively; a fixed support and an elastic support are arranged between the V-type blocks, the fixed support is supported at the right crank of the crankshaft, the elastic support is supported at the left crank of the crankshaft, and the elastic support is automatically adjusted for measurement in a height direction; a detection support realizes front-back and up-down movement along the track of a fixed bracket under driving of the motor; each detection head is corresponding to a detection point of the crankshaft; and due to one-time clamping of the detection device, measurement on the nominal diameter size of each cylindrical surface of the crankshaft, main journal and crankshaft cylindricity, crank and datum plane parallelism degree and the distance between the crankshaft center and the crankshaft reference center can be completed, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical measurement, in particular to a comprehensive detection device for a crankshaft of a small aeroengine. Background technique [0002] The crankshaft is the core moving part of a small aero-engine, and it has higher standards and requirements than ordinary engines in terms of precision and dimensional consistency. [0003] The traditional crankshaft inspection is to use a micrometer to measure the nominal size of each cylindrical surface, and use a V-shaped block and a dial gauge to measure the cylindricity of the main journal. In addition, a special inspection tool is required to measure the cylindricity of the crankshaft, the parallelism of the crankshaft, and the eccentricity of the crankshaft. . Traditional detection methods have low efficiency and large random errors. [0004] Patent CN202195790U discloses "a special detection device for crankshaft". The detection device includes a workben...
