Description
Technical field: this utility model patent is used for metal cutting process and quality testing field, for a kind of novel intelligent
Screw thread repair system, is mainly used in the automatic of original inside and outside old thread on whorl work piece and repairs truning fixture with groove and add
Working medium amount qualification determination device.
Background technology: be widely present in petroleum industry on the basis of the original helix of thread of thread part and carry out spiral shell again
Digital control processing that whim is cut and the heavy problem of thread part quality testing, due to its need to carry out on original thread groove with
Groove cutting, it is difficult to ensure that the zero signal of spindle of numerical control lathe occurs position consistent with original helix of thread starting point, with
Time screw thread that turning is completed, generally use and artificial use 6 jin of heavy thread gages to measure its compact distance to judge thread part
The most qualified.
As a example by oil drill rocker, China's oil industry high speed development, substantial amounts of oil drill rocker is applied in petroleum drilling and mining, and
The internal and external screw thread being just located against its two ends between drilling rod is end to end, and these screw threads transmission moment of torsion is big, and shock resistance is strong, seals
Requiring that height easily causes deformation, abrasion and local failure, therefore the key parameter to screw thread requires very strict, damages majority
For bad lighter screw thread, people always want to numerically controlled lathe can make the original screw thread of bit alignment as manual operations
After groove, it is possible to cut along its former helix reparation, the most not only improve working (machining) efficiency but also save tubing and cutter.People simultaneously
It is time saving and energy saving to wish still, quick and precisely completes automatically detecting at machine of thread part, can give for underproof workpiece
Go out cutter to mend, directly repair.But current domestic numerical control lathe does not possess above two function, its Repair gene process can only be
The screw thread that after first being fallen by original threaded portion car, turning makes new advances again, this processing method makes oil drill rocker produce pole in length
Big waste.In actual processing, turning fall the value of part tubing often than screw thread the processing charges of whole turning again also want
High.General oil drill rocker is about 10 meters, weighs 300 kilograms, has bigger deformation before reparation, installs centering difficulty when processing is repaired,
The length stretched out in spindle chuck is difficult to accurately control, and therefore can not the most axially position, traditional digital control processing
This problem can not be solved, on numerically controlled lathe during cutted thread, lathe spindle must be provided with photoelectric encoder, with photoelectricity
The part signal of encoder is as synchronizing signal, it is ensured that the most disorderly detain during processing screw thread.Therefore, screw thread is repaired with numerical control method processing
Time, in order to be able to cut by original thread groove, when screw thread is installed, photoelectric coding in the starting point of palpus guarantee helix of thread and main shaft
The zero signal of device is corresponding, it is achieved circumferencial direction positions, but this this kind of situation in reality is processed can not occur, because of
The Repair gene that this domestic each oil field tubulars substation uses manual lathe to carry out petroleum drilling rod screw-thread substantially；Operator needs manually to remove
Transport about 6 jin of heavy thread gages, and be tightened onto on the thread part machined and judge that crudy is the most qualified, this contact
The detection mode of formula, takes time and effort, and anthropic factor is high, measures inaccurate.In Numeric Control Technology wide variety of today, screw thread is with groove
Repair gene and quality testing become a corner forgotten by people.
