Abstract

The invention provides a coaxial alignment device for an engine and a reverse towing torque detection system, and relates to the technical field of engine cold test preassembly, and the coaxial alignment device comprises a butt joint bottom plate, a fixed bottom plate, an assembly top plate, a cold flow test device, a fixed base, a movable base, an engine, a connecting rod, a hydraulic cylinder C, a hydraulic cylinder D, a hydraulic cylinder B and a hydraulic cylinder A; a limiting groove is machined in the top of one end of the fixed bottom plate, and a supporting strip is slidably connected into the limiting groove. According to the technical key points, based on the fact that the axis of a connecting disc on an engine and the axis of a testing gear on a cold flow testing device are located in the same horizontal plane, the axis of the engine is corrected to be in the horizontal plane and the axis of the engine is corrected to be in the vertical plane; the axis of the connecting disc on the engine is aligned with the axis of the testing gear on the cold flow testing device, so that stable and rapid butt joint can be ensured when the testing gear on the cold flow testing device is close to the connecting disc on the engine.
