What traditional centrifugal blower shell adopted is the form processing of loose mail plate welding combination, this processing mode combined fan shell loose mail quantity is large, the connection mouth of required welding is many, not only operator's labor intensity is large, manufacturing efficiency is low, and owing to need through a large amount of welding clustered operations, large, the Dimensions disunity of the shell modification amount of blower fan, for the assembly and adjustment operation of back impacts, quality of product can not be guaranteed.In addition, because the technical requirements of welding combination processing is higher, operator's technical ability is required also relatively to improve, when operator's level of skill is uneven, also just directly affect product quality.
The model utility content
The purpose of this utility model provides a kind of location assembling that is easy to, and effectively reduces a kind of bag bone Centrifugal Fans Shell of welding modification.
For achieving the above object, the technological scheme that the utility model adopts is: a kind of bag bone Centrifugal Fans Shell, it is characterized in that: be provided with in pairs the shell side plate in the left and right sides, between two shell side plates, be provided with the spiral case plate, the left and right sides of this spiral case plate is provided with locating slot, and the spiral case plate is connected with the mutual buckle of shell side plate by locating slot; On the splicing mouth of spiral case plate and shell side plate end, also be provided with adpting flange.
Preferably, described locating slot bending and molding on the spiral case plate.
Preferably, described locating slot groove width is greater than shell side plate thickness of slab, shell side plate and locating slot Spielpassung.
Preferably, described clamping slot depth is 10mm.
Preferably, fixing by being welded to connect between described shell side plate, spiral case plate and the adpting flange.
Preferably, also be provided with through hole on the described shell side plate, the through-bore axis on the two shell side plates overlaps.
Preferably, described spiral case plate is that the snail type is circular-arc, and its circular arc centroid axis overlaps with through-bore axis.
Preferably, the described through hole outside is along being evenly equipped with several attaching nuts week.
Preferably, described attaching nut is Insert Nut.
After the utility model adopts said structure, owing to after having adopted the housing assembling form of bag bone formula, improved the Location accuracy of housing assembling, reduce housing welding interior stress modification, improve the efficiency of assembling of housing.The utility model is simple in structure, is easy to assembling and positioning, is conducive to extensive modularization production.
