(3). after the end face levelling that will process, with pressing plate, locating shaft is compressed to locking, and use alignment pin that the seam dish of adjustable angle plate and locating shaft is fixed, start to process an end face and seam;
(4). after the one side completion of processing of valve, alignment pin is extracted, unclamp the pressing plate on locating shaft, rotation locating shaft, by the dowel hole on locating shaft seam dish, alignment pin is locked to guarantee the requirement of position degree, again by the pressing plate locking on locating shaft, finally by its excess-three of valve face completion of processing.
A kind of Special mould of heavy caliber water intake ball valve valve processing technology, it is characterized in that: comprise positioning disk, locating shaft, location bent plate and adjustable angle plate, positioning disk is two, it is separately positioned on the two ends, left and right of valve and adopts valve access opening to position, these two positioning disks connect by screw rod tightening, the outside of these two positioning disks is all located and is connected a locating shaft, and a pressing plate is all installed by jackscrew in each locating shaft top; Location bent plate and adjustable angle plate are oppositely arranged, and on this location bent plate and adjustable angle plate, are all shaped with installing hole, and two locating shafts are inserted into respectively in installing hole made on location bent plate and adjustable angle plate.
And described locating shaft consists of main shaft and seam dish, one end of main shaft is inserted in the installing hole of location bent plate or adjustable angle plate, and the other end of main shaft is coaxially made seam dish, and these two seam dishes are all fixedly mounted with and are connected with positioning disk by screw; Along the circumferential direction uniformly on the seam dish adjacent with adjustable angle plate make one group of dowel hole, adjustable angle plate and seam dish are connected by the alignment pin being inserted in one of them dowel hole.
And described screw rod is a plurality of, it is arranged on respectively the top and bottom of positioning disk.
And, also comprising a positioning plate, location bent plate is arranged on the bed surface of lathe by this positioning plate.
Advantage of the present invention and good effect are:
1, this technique and mold accurate positioning, with strong points, every position degree that can meet valve after use requires, improves product percent of pass.
2, owing to using this technique and mold can solve the orientation problem in valve processing, so valve can process on lathe, thereby significantly shortened process time, improved operating efficiency.
3, the present invention is a kind of reasonable in design, easy to use, processing technology and Special mould thereof of being easy to the heavy caliber water intake ball valve valve realized, this mold processing is simple, accurate positioning, can realize by Boring machine processing and change the object that lathe is processed into, therefore by using this mold and technique both to guarantee the specification requirement of workpiece, saved again between machining period, improved operating efficiency, be especially applicable to being applied in large-scale industrial production.
