Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the top view of the centrifugal blower impeller blade locking device that the utility model provides;
Fig. 2 is the sectional view of the centrifugal blower impeller blade locking device that the utility model provides.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.
Please refer to the top view that Fig. 1 and Fig. 2, Fig. 1 are the centrifugal blower impeller blade locking devices that the utility model provides, Fig. 2 is the sectional view of the centrifugal blower impeller blade locking device that the utility model provides.
Described centrifugal blower impeller blade locking device 1 comprises the first clamp 11, first backing plate 12, second clamp 13, second backing plate 14, base 15, screw rod 16, nut 17 and positioning disk 18.
Described base 15 is convex stepped disk, and the boss of described base 15 is fixed in described screw rod 17 one end, and the other end runs through described second backing plate 14, described second clamp 13, described first backing plate 12, described first clamp 11 and described nut 17 simultaneously successively.
Described screw rod 16 and described nut 17 quantity comprise multiple, and multiple described screw rod 16 and described nut 17 acting in conjunction make between each parts of described centrifugal blower impeller blade locking device 1 without relative movement.
Described positioning disk 18 is sheathed on the boss of described base 15.The external diameter of described positioning disk 18 equals the internal diameter of enclosing cover for impeller, thus ensures that enclosing cover for impeller is concentric with described centrifugal blower impeller blade locking device 1, makes described centrifugal blower impeller blade locking device 1 accurately locating blades position.
Before welding blade, the blade shape first welded as required designs the structure of described centrifugal blower impeller blade locking device 1.
With the axis of described base 15 for vertical direction, set up three-dimensional system of coordinate in a computer.The dimensional parameters of blade is inputed to described three-dimensional system of coordinate, forms the threedimensional model of blade.Design the shape of described first clamp 11 and described second clamp 13 according to described threedimensional model, and determine described first clamp 11 and described second clamp 13 coordinate relative to described base 15.
Sheet material cuts out described first clamp 11 and described second clamp 13.According to described first clamp 11 and described second clamp 13 coordinate relative to described base 15, select described first backing plate 12 of suitable thickness and described second backing plate 14.Ensure described first clamp 11 and described second clamp 13 relative to coordinate and described first clamp 11 calculated of described base 15 and described second clamp 13 consistent relative to the coordinate of described base 15.
Described positioning disk 18 being sheathed on the boss of described base 15, being buckled in described base 15 by needing the enclosing cover for impeller welding blade.Successively described second backing plate 14, described second clamp 13, described first backing plate 12, described first clamp 11 and described nut 17 are placed in described base 15 subsequently, and are run through by described screw rod 16 simultaneously.
Screw described nut 17, make between each parts of described centrifugal blower impeller blade locking device 1 without relative movement.
During welding blade, the blade quantity first welded as required on enclosing cover for impeller stamps the punching of uniform sample.Wheel rotor wheel cap, the blade that needs are welded rushes with place's sample on the one hand and aligns, and abuts on the other hand with described first clamp 11 and described second clamp 13.After having located, by welding set, blade is welded in enclosing cover for impeller.
Get another blade, wheel rotor wheel cap, resetting and welding job, until blade all welds complete.
The blade welding of prior art is mostly simple adopts unitary blade location, and this localization method is difficult to accurately locate ternary twisted blade position, and inefficiency.The described centrifugal blower impeller blade locking device 1 that the utility model provides accurately located the position of the blade needing welding by described first clamp 11 and described second clamp 13, and embodiment is simple, simplifies weld job.The described centrifugal blower impeller blade locking device 1 that the utility model provides solves prior art to be difficult to accurately locate ternary twisted blade position, ineffective technical problem.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included within scope of patent protection of the present utility model.
