Description
Technical field
The utility model relates to welding field, refers more particularly to a kind of centrifugal blower single-suction (single-in let) impeller group hub disk assembly welding frock.
Background technology
At present after single-suction (single-in let) impeller group hub disk assembly welding completes, the deflection of impeller hub disk is very big, hub disk unevenness >=5mm, needs to use hydraulic press repeatedly to impeller hub disk school shape, and local location also needs manufacturing operator manual hot school shape, could by the unevenness school shape of hub disk to≤2mm.And in the shape process of hydraulic press school, often can cause the distortion of impeller front disc or impeller sets entirety, need to carry out school shape again to these deformation position.The defect that above technical scheme exists is that the manufacturing cycle of impeller sets is long, and manufacture efficiency low, manufacturing cost is high.
Utility model content
The defect that the utility model exists for above-mentioned prior art, a kind of centrifugal blower single-suction (single-in let) impeller group hub disk assembly welding frock is provided, this frock comprises assembly welding platform, isometry block, bolt, nut, tool disk, interior round clamp, outer round clamp, tool disk has through hole and grooved hole, be placed on by isometry block on the assembly welding platform of level, tool disk is placed on isometry block; Bolt is each passed through the through hole in tool disk and grooved hole, and with nut, outer round clamp is connected with tool disk with interior round clamp.
Further, the through hole in described tool disk is even circumferential distribution, and is weekly 36.
Further, the circle diameter at described place, the through hole center of circle is 1800mm ~ 3000mm, the 120mm and circle diameter successively decreases from big to small successively.
Further, described grooved hole (9) is 16, and is circumferentially being uniformly distributed.
Further, described grooved hole is groove width is 20mm, and the center of circle of top, grooved hole two semicircle orifice be distributed in respectively diameter be 1500mm and 1000mm circumferentially.
Further, the thickness of described tool disk is 40mm ~ 60mm.
The utility model compared with prior art, after centrifugal blower single-suction (single-in let) impeller group assembly welding, the stress produced in impeller sets assembly welding process, impeller sets and frock can together with take vibration stress relief treatment or annealing in process, realize the elimination of welding interior stress.The single-suction (single-in let) impeller group of having welded, the unevenness energy guarantee≤2mm of its hub disk, does not need to carry out secondary school shape to hub disk again, can guarantee that impeller sets physical dimension meets technical requirement, improve production efficiency, reduce manufacturing cost.
Accompanying drawing explanation
Fig. 1 is the utility model application assembling schematic diagram;
Fig. 2 is the utility model tooling plate structure schematic diagram;
Description of symbols in figure: round clamp, 7 outer round clamps, 8 through holes, 9 grooved holes, 10 impeller sets hub disks, 11 impeller sets in 1 assembly welding platform, 2 isometry blocks, 3 bolts, 4 nuts, 5 tool disk, 6.
Detailed description of the invention
Below with reference to accompanying drawing, the technical solution of the utility model is elaborated, so that those skilled in the art better understand and implement the utility model.
As shown in Figure 1, this centrifugal blower single-suction (single-in let) impeller group hub disk assembly welding frock, comprise assembly welding platform 1, isometry block 2, bolt 3, nut 4, tool disk 5, interior round clamp 6, outer round clamp 7, isometry block 2 is placed on the assembly welding platform 1 of level, tool disk 5 being placed on isometry block 2, realizing the horizontal positioned of tool disk 5, reducing the deformation that scratch diskette 5 produces because placing out-of-flatness.Tool disk 5 there are through hole 8 and grooved hole 9, bolt 3 is each passed through the through hole 8 in tool disk 5 and grooved hole 9, and by outer round clamp 7 and interior round clamp 6, impeller sets hub disk 10 is fixed on tool disk 5 with nut 4, realize the one of impeller sets hub disk 10 and tool disk 5, what the impeller sets hub disk when impeller sets 11 is welded with impeller sets hub disk 10 10 guaranteed was out of shape minimizes.
More specifically, as shown in Figure 2, the through hole 8 in tool disk 5 is even circumferential distribution, and is weekly 36; Described grooved hole 9 is 16, and is circumferentially being uniformly distributed.Better contact with tool disk 5 to realize impeller sets hub disk 10, strengthen the intensity of impeller sets hub disk 10, the distortion of impeller sets hub disk when reducing to weld.The circle diameter at place, through hole 8 center of circle is 1800mm ~ 3000mm, the 120mm and circle diameter successively decreases from big to small successively; Described grooved hole 9 for groove width be 20mm, and the center of circle of top, grooved hole two semicircle orifice be distributed in respectively diameter be 1500mm and 1000mm circumferentially.To meet the application of the impeller sets hub disk 10 of different model and specification.The thickness of tool disk 5 is 40mm ~ 60mm, to ensure the intensity improving tool disk 5, for impeller sets hub disk 10 provides powerful rigidity performance, reduces deformation during its welding.
The utility model can guarantee that the deformation of centrifugal blower fan blade wheel group hub disk assembly welding process reduces, unevenness after assembly welding can ensure at≤2mm, do not need to carry out secondary school shape to impeller sets hub disk after welding again, can guarantee that impeller sets physical dimension meets technical requirement, improve production efficiency, reduce manufacturing cost.
