The present invention repairs device for on-site processing in the specific implementation for nuclear plant pressure vessels flange and screw, centering assembly 4 remaining bolt and screw are carried out multiple spot detection in order to find out bolt and empty, screw thread rehabilitation center and screw thread reparation play tooth point, by changing different cutters 22 on cutter connecting rod 21, being sequentially completed on pressure container flange face and kill the taking-up of bolt and the repair of screw thread, solid waste collection assembly 5 takes out at bolt and is circulated suction bits in screw thread repair process.
Seeing Fig. 2, repair the embodiment one of on-the-spot processing method for the present invention for nuclear plant pressure vessels flange and screw, the present embodiment comprises the following steps for nuclear plant pressure vessels flange and screw reparation scene processing method:
Step S10, is installed in the step on pressure container flange face by device for on-site processing body；When being embodied as, screwing in plug screw during processed hole rotates hole, adjacent the 1st and the 4th hole counterclockwise on Ring Shape Pressure Vessels flange face, plug screw upper surface is less than flange face more than basal plane 10mm.Being placed in by device for on-site processing on pressure container flange face, front end semi-circular parallels falls in hole, corresponding location: and then, load onto front end clamp plate, adjusts two front end levelling bolts and adjusts X-direction level；Rear end uses spy to order adjustable sizing block, and three coordinates adjustment to adjust machine tool horizontal.
Step S20, sets up the step of the coordinate system of processed screw；When being embodied as, using the lathe each axial coordinate direction after installation as processed hole coordinate direction, disk upper surface is recorded a little as Z=0 with gauge head, survey one week any three point (or more than 3) in residual bolt side with gauge head and can calculate remaining bolt Zhou XianX Y machine coordinate values, put as adding circle interpolation central point in man-hour using this.Dust exhaust apparatus 51 is rotated to front end, and fixes.In the course of processing, dust suction cycle period can be set by the programming of storage, start vacuum cleaner, mobile suction nozzle axis and processed axially bored line essentially coincide (determining this point coordinates after setting up lathe coordinate system) and realize inhaling bits function, along with hole depth increases, when inhaling bits, the degree of depth of suction nozzle feeding also increases every time, until process finishing.
Step S30, changes the step of cutter after removing residual bolt；
Step S40, liftable bits-suction device carries out rotating and carry out to inhale the step of bits relative to device for on-site processing body；When being embodied as, cleaner suction nozzle, according to the position coordinates set, is directed at processed hole and carries out inhaling bits.When bits inhaled by needs to deep hole, single axis robot carries it progressively to move down, until processing this hole.
Step S50, uses the step of the mode milling screw of spiral interpolation.When being embodied as, use spiral interpolation mode to process, generally should process secondary, for the first time after processing, after measuring central diameter, change interpolation arc radius or change tool radius, carry out polish.
Further, also include step S60, the screw thread silk remained in kingbolt hole is rolled, and remove the step of kingbolt light section part.When being embodied as, with the use of hand-operated tools, the screw thread silk remained in kingbolt hole is rolled out；And then, remove remaining light section part after emptying: hand-operated tools can be used to take out, electric magnet instrument is inserted light section, light section can be taken out smoothly by suction.
Further, also include step S70, detection and judge the step that the screw thread that processed is the most qualified, if it is determined that it is defective, the step then according to the type of defect, screw repaired. when being embodied as, if qualified, bolt is killed process and is completed, if defective, need according to defect type, screw to be reprocessed.If when defect on a large scale occurs, needing reaming reparation.
Implement the on-the-spot processing method repaired for nuclear plant pressure vessels flange and screw of the present invention, device, have the advantages that
The first, remove residual bolt and be just capable of the work such as reparation of the emptying of bolt, screw thread by changing the cutter on cutter connecting rod, and the spiral interpolation mode used is without coolant and lubricating fluid, the efficiency that the scene processing of lifting is repaired, solve frequently to change cutter and more exchange device, the problem of inefficiency, safe and reliable.
The second, set four-shaft numerically controlled and servopackage, can promote the accuracy of dimensioned；Set video monitoring and remotely operating assembly can realize freely switching of Local or Remote operation, it is possible to reduce the radiation dose of maintainer.
3rd, device for on-site processing body is installed on pressure container flange face the parallels structure enforcement being provided with by bottom, it is not necessary to additionally set for this platform, and installs location rapid and accurate.
4th, can be without changing cutter in a cycle of operation, aneroid gives up and discharges and the problem of collection；Meanwhile, by arranging liftable bits-suction device, it is possible to the convenient scrap discharge that will produce.
