Description
Technical field
The utility model relates to mould, particularly relates to a kind of draught fan impeller dish particular manufacturing craft.
Background technology
At present, the hole in draught fan impeller dish is normally processed by large-sized numerical control Longmen machine tool, and processing cost is high, and on the impeller disk, the size in hole and angle are all difficult to ensure precision.
Utility model content
The utility model proposes a kind of draught fan impeller dish particular manufacturing craft, to ensure size and the angle of draught fan impeller dish mesopore, make the drilling operation of draught fan impeller dish become more simple, convenient, processing cost is low.
To achieve these goals, the utility model proposes a kind of draught fan impeller dish particular manufacturing craft, described mould comprises a cylindrical tire plate, be arranged at the centre bore of described tire plate center, be arranged at multiple unthreaded holes that described tire plate regularly distributes, the drill bushing mated with described unthreaded hole, and the hollow cylindrical boss being arranged at place of described Tai Ban bottom center; The hollow diameter of a circle of described hollow cylindrical boss is identical with the diameter of described centre bore, the diameter of described hollow cylindrical boss is corresponding with the diameter of the spindle hole of draught fan impeller dish, and the height of described hollow cylindrical boss is less than the height of draught fan impeller dish spindle hole; Tapping is set being placed on the described drill bushing outer surface in described unthreaded hole, the inwall of described unthreaded hole arranges the mantle fiber matched with described tapping, described unthreaded hole and described drill bushing are formed and is threaded.
The beneficial effect of the program of the present utility model is that above-mentioned mould can ensure size and the angle of draught fan impeller dish mesopore, and make the drilling operation of draught fan impeller dish become more simple, convenient, processing cost is low.
Preferably, the upper surface of described tire plate is provided with three suspension centre rings, and described three suspension centre ring distributions triangular in shape, conveniently make described mould be separated with draught fan impeller dish.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is further described.
Known in conjunction with Fig. 1-2, draught fan impeller dish particular manufacturing craft involved by the utility model comprises the cylindrical center bore 2 having certain thickness cylindrical tire plate 1, be arranged at described tire plate 1 center, be arranged at the multiple cylindrical unthreaded hole 3 that described tire plate 1 regularly distributes, the drill bushing 4 mated with described unthreaded hole 3, and being arranged at the hollow cylindrical boss 5 at place of described Tai Ban 1 bottom center, the hollow diameter of a circle of described hollow cylindrical boss 5 is identical with the diameter of described centre bore 2.The diameter of described centre bore 2 is much smaller than the diameter of described tire plate 1; The diameter of described hollow cylindrical boss 5 is corresponding with the diameter of the spindle hole of draught fan impeller dish, and the height of described hollow cylindrical boss 5 is less than the height of draught fan impeller dish spindle hole, when described drill bushing 4 is with described unthreaded hole 3 Matching installation, the bottom of described drill bushing 4 and the bottom surface of described tire plate 1 are in same level, and the top of described drill bushing 4 is higher than the upper surface 1 ~ 2cm of described tire plate 1.
In use, described mould is used for the boring of draught fan impeller dish, and therefore described drill bushing 4 belongs to consumable accessories, holes frequently, the aperture of described drill bushing 4 can be caused to become large, and then cause boring bit location offset and affect borehole accuracy.Therefore in order to ensure borehole accuracy, described drill bushing 4 adopts seamless and dismountable assembling mode with described unthreaded hole 3, has both ensured to fit tightly between described drill bushing 4 and unthreaded hole 3, and has ensured again, when described drill bushing 4 loss, can change in time.
Concrete, described drill bushing 4 can adopt hollow cylindrical steel part, and arranges tapping 41 being placed on described drill bushing 4 outer surface in described unthreaded hole 3, as shown in Figure 3, the inwall of described unthreaded hole 3 arranges the mantle fiber matched with described tapping 41.During use, described drill bushing 4 is carried out fastening installation with described unthreaded hole 3; When needing to change drill bushing 4, it is threadingly dismantled.
Concrete, the installation diagram of the mould A involved by the utility model and draught fan impeller dish B as shown in Figure 4, the hollow cylindrical boss 5 of mould A is mated with the spindle hole B01 of draught fan impeller dish B and locates, and compressed by pressing plate, utilize drill bit to enter drill bushing 4 afterwards and hole.
Mould A conveniently involved by the utility model is separated with draught fan impeller dish B, can cast three suspension centre rings 6 at the upper surface of mould A, described three suspension centre ring 6 distributions triangular in shape, as shown in Figure 5.
Draught fan impeller dish particular manufacturing craft involved by the utility model can ensure size and the angle of draught fan impeller dish mesopore, and make the drilling operation of draught fan impeller dish become more simple, convenient, processing cost is low.
