 Ever looked at a transmission or a distribution or line hardware forged or cast fitting ball or socket and thought “how do I tell if this is exactly what it should be and it is OK?!”
For some items, it is a simple matter of measurement to prove that the fitting is dimensionally acceptable. For example for a 160kN clevis, it is a case of measuring the width of the clevis and the diameter of the pin.
The fit between ball and socket fittings is equally as critical and clevis and tongue but impossible to measure on site other than by fitting the two items together for a quick physical check. However, this type of inspection will prove only that the items don’t mechanically foul one another: it won’t prove compliance with the standard that defines the size and shape of the IEC16mm and 20mm ball and socket fittings. Enter Ball and Socket Go/No Go gauges!
The principle of Go/No Go gauges is simple. If a “Go” gauge fits the item being measured, it’s OK. If a “No Go” gauge fits the item being measured, something is amiss! At Electropar, to ensure that all ex production ball and socket fittings are dimensioned in accordance with relevant standards we sample test each batch of ball and socket forgings in accordance with a sampling plan.
This work is done with our own set of calibrated Go/No Go gauges, shown in the picture adjacent. The Go/No Go gauges have been calibrated with a (cmm) post manufacture, and certified as dimensionally correct to within 1000th of a millimetre.
When Electropar delivers ball and socket fittings, we don’t just say “they are correct”, we can prove it! For more information contact camw@electropar.co.nz
