And, described locating shaft is made up of main shaft and seam dish, and 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 coaxially makes seam dish, and these two seam dishes are fixedly mounted with location dish each through screw and are connected；On the seam dish adjacent with adjustable angle plate, along the circumferential direction uniform one group of dowel hole, adjustable angle plate and the seam dish made is connected by the alignment pin being inserted in one of them dowel hole.
And, described screw rod is multiple, and it is separately mounted to the top and bottom of location dish.
And, also including a positioning plate, location bent plate is arranged on the bed surface of lathe by this positioning plate.
Advantages of the present invention and having the benefit effect that
1, this technique and mold accurate positioning, with strong points, the every position degree that can meet valve after using requires, improves conforming product rate.
2, owing to using this technique and mold to can solve the problem that the orientation problem in valve processing, therefore valve can be processed on lathe, thus process time being greatly shortened, improve work efficiency.
3, the present invention is a kind of reasonable in design, easy to use, processing technique of heavy caliber water intake ball valve valve of being easily achieved and Special mould thereof, the processing of this mold is simple, accurate positioning, can realize being changed into the purpose of lathe process by Boring machine processing, therefore by using this mold and technique both to ensure that the technology requirement of workpiece, save again between machining period, improve work efficiency, be particularly suitable for application in large-scale industrial production.
