Abstract
The utility model discloses an impeller welding frock for centrifugal blower, it includes support, rotary mechanism and tilting mechanism. The utility model provides an impeller welding frock for centrifugal blower, guarantees that the welding quality of impeller reaches the welding process requirement, improves the welding process efficiency of impeller, reduces the workman and polishes the welding seam time, practices thrift the impeller and makes artifical cost, does benefit to the popularization and application of industrialization large -scale production.
Description
Technical field
The utility model belongs to the attached auxiliary equipment field of air blast, particularly a kind of impeller welding frock for centrifugal blower.
Background technology
For centrifugal blower, impeller, also known as active wheel, is the topmost parts of compressor.Impeller with main shaft High Rotation Speed, to air work.Gas is under the effect of impeller blade, and and then impeller does High Rotation Speed, and flow by the diffusion in the effect of rotary centrifugal force and impeller, when flowing out impeller, the pressure of gas, speed, temperature are all improved.Impeller is welded primarily of wheel disc, wheel cap, deviated splitter vane, import circle.According to fan design requirement, the deviated splitter vane of some is uniform to be welded between wheel disc and wheel cap, the narrow space of welding operation, and therefore the putting position of impeller is very important; The welding process requirement deviated splitter vane of impeller wants symmetrical staggered welding, after horizontal position welding simultaneously, requires weld seam level, so just needs often to move impeller until optimum welding position; Blade has welded rear needs polishing welding seams in narrow space, and put correctly impeller location can improve weld grinding efficiency.At present, because of the comparatively large and heavier-weight of impeller, welding tooling for centrifugal blower impeller mostly is truss handling to welding post, then directly to be welded by welder or manpower fixes impeller, this mode is convenient to impeller and is moved but be not easy to fix, even if find optimum welding position to be also not easy accurate welding, affect impeller welding quality, production efficiency is low simultaneously.The utility model patent that patentee is " Shangyu Special Fans Co., Ltd. ", application number is " CN201320643979.5 " discloses a kind of welding tooling of centrifugal blower fan blade wheel, although improve welding tooling to a certain extent, but this welding tooling moves, overturns inconvenience, fundamentally can not solve and find optimum welding position and fixing problem, use this frock also to require impeller putting position is wanted precisely simultaneously, this mode does not reduce the workload that labour intensity increases the weight of on the contrary, is unfavorable for industrialization large-scale production.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of impeller welding frock for centrifugal blower, ensure that the welding quality of impeller reaches welding process requirement, improve the welding processing efficiency of impeller, reduce workman's polishing welding seams time, save impeller manufacture of intraocular cost, be beneficial to applying of industrialization large-scale production.
For realizing above-mentioned technique effect, the utility model provides a kind of impeller welding frock for centrifugal blower, it comprises support, rotating mechanism and switching mechanism, support comprises left socle and right support, left socle and right support are fixedly installed on basal plane respectively, are connected between left socle and right support by reinforced pipe; Rotating mechanism comprises supporting disk, pressure ring, gland, screw rod, nut and spacing set bolt, spacing set bolt arranges two, two spacing set bolts are symmetrical arranged centered by the supporting disk center of circle, impeller is connected with supporting disk with nut by pressure ring, gland, screw rod, and impeller can rotate around screw rod and fix by spacing set bolt on supporting disk; Switching mechanism comprises upset main shaft, bearing block, gear, worm screw and handwheel, bearing block is fixedly installed on left socle, upset main shaft one end is connected with the bearing in bearing block, the upset main shaft other end is connected with gear, gear and worm engaging, worm screw is connected with handwheel, and handwheel is arranged on right support; The supporting disk of rotating mechanism is fixedly installed on upset main shaft.Rotate handwheel, under the effect of worm screw and gear, upset main shaft rotarily drives supporting disk and realizes 360 ° of upsets; Impeller is fixed on supporting disk by securing member, and rotary blade makes it along screw rod 360 degree rotation manually, when vane rotary is to correct position, by the fastening impeller of bolts at two ends, by rotating impeller multi-direction 360 and fixing, is convenient to find optimum welding position.
The utility model is further improved, described a kind of impeller welding frock for centrifugal blower also comprises ballast box, and ballast box is arranged on upset main shaft, and the center of gravity of ballast box and the center of gravity of impeller are along overturning main shaft symmetry, unexpected center of gravity unstability during to prevent from overturning, eliminates safe hidden trouble.
A kind of impeller welding frock for centrifugal blower that the utility model proposes, ensure that the welding quality of impeller reaches welding process requirement, improve the welding processing efficiency of impeller, reduce workman's polishing welding seams time, save impeller manufacture of intraocular cost, be beneficial to applying of industrialization large-scale production.
