Description

Heavy caliber water intake ball valve valve processing Special mould
Technical field
The utility model relates to valve technology field, especially a kind of heavy caliber water intake ball valve valve processing Special mould.
Background technology
According to the needs of hydroelectric station operation and maintenance, water channeling type unit must arrange inlet valve before every spiral case, water blockoff or cut off current when accident when guaranteeing maintenance, along with the development in China power station in recent years, the water intake ball valve product of heavy caliber, pressure level, hard sealing structure is able to extensive use.In this type of ball valve, large and the pressure stage height of bore is its feature, the design form of valve has very large different (seeing Fig. 1) from the valve of ordinary ball valve, in this type of ball valve, adopt the valve design (sealing sphere is set on valve) as figure to save the operation of processing whole sphere, the valve shaft needs that can meet high pressure with bolts.
For guaranteeing position degree on four sides, the manufacturing procedure of this type of valve adopts following steps conventionally: vehicle passage hole (comprising technique seam), and------the another side of rotary table boring is inlayed sealing ring seam and end face for the another side edge valve shaft seam of rotary table boring and end face---rotary table boring edge sealing ring seam and end face---to take technique seam as location boring edge valve shaft seam and end face.
Above-mentioned processing method can meet the requirement of every position degree of valve, but the processing progress that its shortcoming is boring machine is limited, so process velocity is slow, efficiency is low, can not meet the needs of large-scale production.
Summary of the invention
The purpose of this utility model is to provide a kind of can increase work efficiency, guarantee the heavy caliber water intake ball valve valve processing Special mould of registration and product quality.
The purpose of this utility model realizes by following technological means:
A kind of heavy caliber water intake ball valve valve processing Special mould, 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 utility model and good effect are:
1, this Special mould 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 Special mould can solve the orientation problem in valve processing, so valve workpiece can process on lathe, thereby significantly shortened process time, improved operating efficiency.
3, the utility model is that a kind of heavy caliber water intake ball valve valve reasonable in design, easy to use, that be easy to realize is processed Special mould, 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 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.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of valve;
Fig. 2 is the installation diagram of valve and mold;
Fig. 3 is the front view of locating shaft seam dish.
The specific embodiment
Below in conjunction with accompanying drawing, describe embodiment of the present utility model in detail; It should be noted that, the present embodiment is narrative, is not determinate, can not limit protection domain of the present utility model with this.
As shown in Figures 2 and 3, a kind of heavy caliber water intake ball valve valve processing Special mould, comprise positioning disk 3, locating shaft, location bent plate 9 and adjustable angle plate 11, positioning disk is two, it is separately positioned on the two ends, left and right of valve 2 and adopts valve access opening to position, these two positioning disks connect by screw rod 1 tightening, and screw rod is a plurality of, and it is arranged on respectively the top and bottom of positioning disk.
The outside of two positioning disks is all located and is connected a locating shaft, and a pressing plate 7 is all installed by jackscrew 6 in each locating shaft top.This locating shaft consists of main shaft 8 and seam dish 5, 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 is coaxially made seam dish, and these two seam dishes are all fixedly mounted with and are connected with positioning disk by screw 4.
Location bent plate is arranged on by positioning plate on the bed surface of lathe, and 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.Along the circumferential direction uniformly on the seam dish of the locating shaft fitting with adjustable angle plate make one group of dowel hole 10, adjustable angle plate and seam dish are connected by the alignment pin 12 being inserted in one of them dowel hole.
