It carries out, standard clear stipulaties evaluation sample will meet relative tolerance size regulation using limit sample, so special thread connects
The test agent processing of head dimension limit is the general character problem that current each special thread Development institution faces, and is mainly the following original
Cause：First, tubing and casing radius-thickness ratio is relatively large, is easily accommodated and deformed；It is second is that close in Special threading connector dimension limit test agent
Front cover and central diameter tolerance range are relatively narrow, and generally at 3 μm or so, tubing is in clamped state during screw thread process, has small
Flexible deformation, on-line checking thread parameter is all in the control margin of tolerance, but after tube body is unclamped by fixture, flexible deformation is extensive
It is multiple, it is overproof so as to cause processed thread parameter ovality；Third, what the processing of Special threading connector dimension limit test agent used
Pipe is usually the tubing for meeting API relevant criterions, and this tubing ovality is generally large, is influenced to be more easy to occur by clamping external force
Flexible deformation, therefore Special threading connector limit sample processing lumber recovery is low, efficiency is low, extends the research and development of products cycle.
So developing a kind of inner supporting device of tubing external screw thread processing, oil jacket tubing external screw thread limit tolerance ruler is improved
The qualification rate of very little sample processing is particularly important；Meanwhile can be that new-product development saves more quality time, shorten new production
Also there is important meaning in the product R＆D cycle.
