The course of work of the present invention is as follows:
1, one end of sand control screen is installed on the central shaft hole 2030 of rotating disk of vertical sleeping turntable 20, anotherOne end is placed on the universal wheel 30 of supporting base of supporting device 3;
2, open NC machine 10, start the first motor 204 and the second motor 205 by NC machine 10,Making needs the position of groove milling to adjust to milling cutter 403 places corresponding to groove milling mechanism 4 on the tube wall of sand control screenPosition and upward (when milling head 40 have multiple and while working together, corresponding multiple positions simultaneously);
3, close the first motor 204 and the second motor 205, primer fluid pressure control system 50, makes hydraulically operated fixtureThe first grip block 511 of 51 moves to the second grip block 512 sand control screen that is clamped;
4, the drive motors 401 of groove milling mechanism 4 slides and just makes milling cutter 403 to sand control screen on base 400The top, position that needs groove milling on tube wall for sand control screen, starts drive motors 401 and makes milling cutter 403 limitsHigh speed rotating limit slow decreasing, until process groove on the tube wall of sand control screen.
While processing the groove of multiple annular array on need to the tube wall at sand control screen, further comprising the steps of:
5, milling cutter 403 rises return, and the first grip block 511 is to the direction motion that deviates from the second grip block 512And unclamping sand control screen, the second motor 205 drives described rotating disk 203 to rotate certain angle and described in drivingSand control screen rotates certain angle, and then the first grip block 511 is solid to the second grip block 512 motion clampingsSurely live sand control screen, milling cutter 403 high speed rotating limit, limit slow decreasings, until add on the tube wall of sand control screenWork goes out groove;
6, repeating step 5, until process multiple grooves of annular array on the tube wall of sand control screen.
Process multiple grooves arranged in a straight line along its length on need to the tube wall at sand control screen, and milling head40 quantity or the lazy weight of simultaneously working are with disposable while processing all grooves, further comprising the steps of:
7, milling cutter 403 rises return, and the first grip block 511 is to the direction motion that deviates from the second grip block 512And unclamping sand control screen, the first motor 204 drives described screw rod 2011 to rotate and drives described slide 202 edgesSlide rail 2010 linear slide, other that make sand control screen need the position of groove milling to adjust to corresponding to groove milling mechanismAbove-mentioned steps 3 and 4, is then carried out also upward in the position at 4 milling cutter 403 places;
8, repeating step 7, until process multiple arranged in a straight line along its length on the tube wall of sand control screenGroove.
Be appreciated that by the permutation and combination to above-mentioned steps, can realize more complicated sand control screenGroove milling work, will not enumerate here.
Known by above-mentioned detailed description of the invention, the present invention has realized the tube wall of sand control screen automaticThe object of groove milling, greatly reduces production cost and labour intensity, has improved production efficiency, meets wellEnterprise's low cost, high efficiency Production requirement, also for extensive, the automated production of enterprise provide goodGood technical support. And the present invention by arranging the adjustable central shaft hole in aperture, Bing center on rotating diskThe edge of axis hole arranges ratchet, not only can adapt to the sand control screen of different-diameter size, without repeatedly installingDebugging, and install firmly, the central rotating shaft of sand control screen is consistent with the center line of central shaft hole all the time,Thereby guarantee the steadiness of sand control screen installation and the stability of central rotating shaft, the processing that has improved sand control screenPrecision, reduces the service life of producing noise and improving milling cutter; In addition, the present invention passes through universal wheel settingOn the both sides of sand control screen, enough freedoms of motion are not only provided, avoid sand control screen and supporting baseBetween because phase mutual friction is impaired or motion is obstructed, and sand control screen is formed to certain chucking power to keep awayExempt from sand control screen landing or skew from supporting base, thereby play certain positioning action, further improvedThe machining accuracy of sand control screen, has eliminated the potential safety hazard existing in process, makes process saferReliably.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every profitThe equivalent structure of doing by description of the present invention and accompanying drawing content or the conversion of equivalent flow process, or directly or indirectly transportBe used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
