Abstract
The utility model relates to a thread end face high precision positioning device in a non-contacting photoelectric testing system for testing petroleum pipe thread parameters. After being positioned by the device, the thread of a petroleum casing pipe to be tested will not be interfered by vibration and has good testing repeatability and high stability. The utility model comprises a thick contrapuntal and pyramidal body; three position sensors are arranged on the thick contrapuntal and pyramidal body; a positioning end face is arranged in the thick contrapuntal and pyramidal body; a tube end positioning outer diameter is arranged on the upper part of the thick contrapuntal and pyramidal body.
Description
The utility model relates to a kind of screw thread end face high-precision positioner that is used for the non-contact optoelectronic test macro of oil pipe thread parameter.
In the background technology, the product quality of employed oil pipe, sleeve pipe directly determines the quality and the life-span of oil gas well in the oil field, wherein the quality of screw thread is particularly important, not only determining strength of joint but also bigger to influences such as sealing property, anti-stick button performances, therefore very important for the quality control and the quality testing of screw thread.But at present a series of measurers such as the feeler gauge that all uses all size, ring gauge, thread single instrument are detected at the scene of oil pipe thread parameter, belong to contact manual measurement instrument, it is very big influenced by human factor, poor repeatability, time-consuming taking a lot of work, and detection speed is slow, can't accomplish 100% check thread parameter.Therefore, the check of the production testing of factory and the arrival in oil field all can only be inspected by random samples, is difficult to avoid omission, erroneous judgement or underproof tubing and casing to be gone into the well, and the quality of oil well is caused a hidden trouble.
The purpose of this utility model has been to overcome the weak point in the background technology, a kind of screw thread end face high-precision positioner is provided, this device is used for the non-contact optoelectronic test macro of oil pipe thread parameter, tested petroleum casing pipe screw thread behind this device location can not be given a shock interference, the test good reproducibility, stability is high.
For achieving the above object, the technical solution that the utility model adopts is as follows:
A kind of screw thread end face high-precision positioner, its special character is: comprise thick contraposition cone, thick contraposition cone is provided with position transducer, and thick contraposition cone is interior and be provided with the location end face, and thick contraposition cone upper end is a pipe end location external diameter.
Above-mentioned position transducer can be three.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a duty reference diagram of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in further detail: referring to Fig. 1, comprise thick contraposition cone 1, thick contraposition cone 1 play the guiding role.Thick contraposition cone 1 is provided with three position transducers 2, is provided with location end face 3 in the thick contraposition cone 1, and thick contraposition cone 1 upper end is that pipe end is accurately located external diameter 4.Referring to Fig. 2, during real work, the end face of tested screw thread is put into accurate positioning device, the location end face of the processing datum of petroleum casing pipe screw thread and locating device matches like this, and " the screw thread illumination is divided into two bundles through prism; be imaged onto on the two-way area array CCD by pick-up lens; the vision signal of output is delivered to the collecting image of computer system, handles by data analysis, finishes the automatic measurement of oil pipe thread parameter with measured workpiece 1 by semiconductor light-emitting-diode (LED) collimated light source again.
Compared with prior art, the advantage and the effect that the utlity model has are as follows:
The utility model can be to tested oil in the non-contact optoelectronic test macro of oil pipe thread parameter Casing threads is accurately located, and can not be given a shock interference, and test repeatability is good, and stability is high.
