Description
Technical field
The utility model belongs to coal gas axial flow fan manufacturing technology field, and in particular to a kind of gas axial-flow fan impeller and
The welding tooling of wheel hub.
Background technology
Gas axial-flow fan impeller is the core of coal gas axial flow fan, and the quality of impeller is extremely critical, and its emphasis one is
The material of impeller, second, the production quality of impeller.Generally for impeller material selection, be design link work
Make, according to applying working condition and production capacity, by calculating and checking repeatedly, substantially without too much influence.And the production quality of impeller
It is then the key link that impeller is manufactured, the production quality of the process for making and its quality control method of impeller to impeller
Influence very big, the swaging of impeller, soldering angle slightly deviation just can influence the performance test results of blower fan, the quality of weld seam, more
It is the quality for being directly connected to product.And the welding quality no less important of wheel hub and blade, wheel hub profile is approximately hemispherical, and
And the shape of blade is three-dimensional, such weld seam is not just straight line or plane curve, but space curve shape is presented, welder's weldering
It is access to toward being turn-taked round wheel hub, and often walks several steps to stop adjustment direction and angle, the progress that weld seam can not continue, and
And the attachment weld having is on inclined-plane, wanting that weld seam is more satisfactory will ceaselessly translation-angle.Existing solution is directly with row
Car ceaselessly lifts displacement adjustment, very wastes time and energy, even if so, the weldquality for often welding out is undesirable, shadow
Ring the power of axial flow blower and service life and there is certain potential safety hazard, production efficiency is low, and production cost is uncontrollable.
Therefore it provides a kind of frock for the welding quality that can guarantee that impeller and wheel hub is very necessary.
The content of the invention
In order to overcome it is above-mentioned in the prior art the defects of, the utility model provides a kind of gas axial-flow fan impeller and wheel hub
Welding tooling, the welding tooling can allow welder constantly adjust position and the angle of impeller or wheel hub, and welder welds
Action need not adjust, and the carry out welding job of continued smooth, weld interval be greatly reduced, and improve weldquality, subtract
Lack frequency of doing over again, improved efficiency, reduce cost.
Above-mentioned goal of the invention is achieved through the following technical solutions, a kind of weldering of gas axial-flow fan impeller and wheel hub
Frock, including the ring flange of fixed impeller or wheel hub are connect, it is characterized by, in addition to the horizontal rotating shaft on support, support, horizontal
Rotating shaft is provided with ring flange free-wheeling system, ring flange longitudinal direction switching mechanism；Described ring flange free-wheeling system includes hanging down into cross
The straight solid rotation power transmission shaft in horizontal rotating shaft, the ring flange mounted in rotation power transmission shaft top, on rotation power transmission shaft from
Rotating motor and rotation driven gear, the gear reduced drive mechanism A between spinning motor and rotation driven gear；Described
Ring flange longitudinal direction switching mechanism includes longitudinal turning gear in the horizontal rotating shaft, on horizontal rotary shaft rack or ground
On upset motor, the gear reduced drive mechanism B between longitudinal turning gear and upset motor.
Preferably, described gear reduced drive mechanism A includes the rotation driving tooth on spinning motor output shaft
Wheel, bevel gear pair and umbrella tooth with the first carrier gear A of rotation driving gear engaged transmission, with the first carrier gear A rotations
The the second carrier gear A and the driven gear on rotation power transmission shaft of the second carrier gear A engaged transmissions that wheel set rotates.
Preferably, described gear reduced drive mechanism B includes the first carrier gear engaged with longitudinal turning gear
B, the second carrier gear B, the upset driving gear on upset motor main shaft engaged with the second carrier gear B.
Preferably, described longitudinal turning gear is semi-circle gear；Two are all mutually that the longitudinal of semi-circle gear overturns tooth
Wheel turns over symmetrically mounted in horizontal rotating shaft or so two ends by the respective upset motor being mounted on support or on ground, mounted in longitudinal direction
Gear reduced drive mechanism B drivings between rotating disk and upset motor.
Preferably, two described upset motors are identical synchronous motor, and connect same starting switch and synchronously open
Dynamic and closing.
The utility model has the advantages that compared with prior art：Pass through the ring flange self-revolving machine set in horizontal rotating shaft
Structure, ring flange longitudinal direction switching mechanism, its position of impeller and wheel hub being fixed on ring flange can be adjusted in three dimensions,
Position and the angle of impeller or wheel hub can constantly be adjusted to adapt to, meet welder's welding requirements, guarantee is welded on most preferable
Angle under complete, so as to reach sphere welding, welder's can that do not have to walk up and down carries out whole operations to impeller,
And ensureing weldquality, first mate's degree reduces weld interval, reduces frequency of doing over again, and improves efficiency, reduces cost.And because
For impeller and hub weight weight, need to be installed in driving or crane lifting on ring flange, so horizontal rotating shaft load weight,
It is that the requirement of ring flange is very high to platform, stable platform is advantageous to welding size position during the welding of rotor set impeller and wheel hub
Put centering, and weld job can also apply certain dynamic loading to frock in itself, and with the longitudinal direction of two identical semi-circle gears
Turning gear symmetrically mounted in horizontal rotating shaft or so two ends, makes the ring flange longitudinal direction switching mechanism upset in horizontal rotating shaft more flat
Surely, reliably, safely.
