Description
Technical field
The present invention relates to a kind of locomotive axle box health check-up and survey device and method, belong to railway locomotive manufacturing technology field.
Background technology
The structure of locomotive axle casing is shown in accompanying drawing 1, in its processing and manufacturing process, needs to measure spacing dimension A1 and A2 of endoporus center to pull bar seat surface.But this center, hole is actual is a non-physical empty measurement point, the measurement how realizing this size is technological difficulties.
A kind of method of the prior art utilizes large-scale vernier micrometer to coordinate clamp to measure.This metering system is the end face first snapping into two draw-bar seats with clamp, then measures with milscale the size that clamp measure, i.e. the size of A1+A2, then using this size divided by 2 as the size of A1 or A2.But this result is the mean value of A1 and A2 measurement size in fact.Its actual conditions are likely the multiple different situations such as A1 ≠ A2, A1 < A2 or A1 > A2.That is, although survey A1+A2 entity size numerical value be qualified, A1 or A2 size value is not necessarily qualified.Such as, A1 ≠ A2 just illustrates that the center of A1+A2 size does not overlap with axle box endoporus center, occurs misalignment and dimension overproof phenomenon.Although therefore this metering system work efficiency is high, measuring accuracy cannot be ensured.
Another kind of method of the prior art utilizes three coordinate measuring machine to measure.This method hangs onto on three coordinate measuring machine by workpiece, finds out endoporus center, then detect respectively A1, A2 size by axle box inner diameter edge.Although this measuring method can meet the requirement of measuring accuracy, measuring process is loaded down with trivial details, and the time is long, and efficiency is low, cannot meet the needs of axle box production cycle.
Summary of the invention
