FIELD: flaw inspection of cars' wheel pairs.
SUBSTANCE: automatic assembly for flaw inspection of cars' wheel pairs has unit for feeding wheel pairs provided with mechanism of turn, device for cleaning inspection area, unit for rotating wheel pairs. Control circuits of devices and carriages are connected with control board. Diagnostic aid has electromagnet-acoustic converters placed in carriages. Output of converter is connected with input of data preliminary processing unit through amplifier unit. Data preliminary processing unit is connected with computational unit. Inputs of electromagnet-acoustic converters are connected with corresponding outputs of generator unit. Outputs of synchronization unit is connected with synchronizing inputs of generator unit, of data preliminary processing unit and of control board. Input of synchronization unit is connected with output of mark optical detector. Electromagnet-acoustic converters, mounted in carriages, are disposed in such that that they take maximal available volume of sounding-through of inspected item.
EFFECT: improved precision and truth of inspection; reduced requirements to quality of cleaning of wheel pairs.
