Description
Technical field
The utility model relates to a kind of wheel discs of draught fan impeller to connect positioning tool with blade.
Background technique
Axial flow blower is a kind of important ventilation, cleaner, is widely used in mine, tunnel, the energy, chemical industry, environmental protection
Equal fields.The quality of axial flow blower performance directly depends on the quality of its inner fan impeller.Draught fan impeller generally by blade and
The composition such as wheel disc, wherein wheel disc includes wheel hub, the abdomen disk coaxially arranged with wheel hub in wheel hub is arranged in and connect wheel hub and abdomen
The web of disk.Currently, there are two types of methods for the production of draught fan impeller, one is monoblock type processing method, another kind is seperated
Formula processing method.
Wherein monoblock type processing method is that one group of blade and wheel disc are carried out monoblock cast, although this processing method can solve
The orientation problem of certainly multiple blade consistency differences, but the Mold Making of monoblock cast is difficult, it is at high cost；And single blade is damaged
Bad to cause entire wheel retirement, operation expense is higher.
And split type processing rule is to process blade, wheel disc respectively, then welds single blade again or assembles in leaf
On piece wheel disc.And multiple blades are welded or are assemblied on wheel disc, there are positioning when the welding of multiple blades or assembly, consistency is poor,
The problem of location difficulty, directly affects the efficiency and ventilation quantity of blower if blade position inaccurate after welding or assembly；While this
Kind processing method low efficiency, large labor intensity.
And a kind of aial flow impeller welding is disclosed in the Chinese patent document that Authorization Notice No. is CN206366776U
Equipment is rotatably arranged on platform including platform and shaft, index dial, slide bar and the locating rod being arranged on slide bar, shaft, point
Scale is connect with rotating shaft transmission, is offered on the periphery of the index dial and the consistent positioning of blade quantity on the impeller
Slot, sliding bar are arranged in strip, retaining spring are arranged on slide bar, one end of retaining spring is fixed on slide bar, another
End is against on platform, and locating rod is stuck in locating slot, and shaft is connect with hub drive, and platform is equipped with the branch for being used to support blade
Fagging.In actual use, wheel hub to be welded is arranged and is fixed in shaft, rotating shaft, until locating rod card
In locating slot, locating rod is against in locating slot under the action of retaining spring, support plate is moved to the edge of wheel hub, then
Blade is placed on the supporting plate, starts to weld first blade, after the completion of welding, rotating wheel hub drives shaft rotation, indexing
Disk rotates together, and for locating slot by driving retaining spring to compress upwards with the contact surface of locating rod, locating rod skids off locating slot, and
It is against on the outer peripheral surface of index dial, it is real until index dial turns in next locating slot that locating rod is stuck in rotation direction
Now to the positioning of next blade welding position.And realization rotation is engaged by bevel gear between index dial and shaft.The axis stream
The welding position that each blade is corresponded on wheel disc can be ideally accurately positioned by formula impeller welding equipment, be processed in this way
It is high-efficient, it is easy to process.
But in the equipment during rotating shaft, locating rod stress can voluntarily be skidded off along the groove face of locating slot
Locating slot, this allows for shaft may being caused to rotate due to maloperation, and then locating rod is made to exist during welding blade
It is shaken in locating slot, not can guarantee positioning accuracy then at this time.And need just be transferred on index dial by engagement bevel gear,
Drive mechanism is more complicated when positioning, results in overall structure many and diverse in this way, the precision of each components and mutual
Assembly precision will be guaranteed, while maintenance replacement is many and diverse in individual damage parts.

Screw 017 is detached from the limit block to index dial 005, and next hole location of rotating wheel disk 008 to 005 circumference of index dial is adjusted
It is whole in place after, be inserted into next index hole 020 with stop screw 017, again by index dial 005 lock limit；(9) positive rotation
The levelling control lever for turning Level tune component 200, by the circumference that blade 307 is pressed on wheel disc 008 again carry out welding or
Assembling work；Successively alternately, the production of entire impeller can be completed.
In the actual use process, connection positioning work can quickly realize the circumference graduation and leaf of wheel disc 008
Spatial position adjustment between piece 307 and wheel disc 008 guarantees the consistency of the welding of blade 307 or assembly, improves the matter of impeller
Amount, and then guarantee the performance of axial flow blower；Also the production efficiency of impeller production can be improved, reduce the labor intensity of worker；Simultaneously
Single blade 307 is damaged or worn out, and is removed it and (if welded-type impeller, is needed polishing to clear up after removing damaged blade 307), is led to
The connection positioning tool is crossed, the positioning replacement of new blade 307 can be fast implemented, the service life of entire impeller is improved indirectly, drop
Low operation expense；4. the adjustment positioning tool is of simple structure and low cost, easy to use and reliable.
Certainly in other embodiments, if in order to be adapted to installation position of the blade of different types of draught fan impeller on wheel disc
It sets, can also set multiple for index dial, upper and lower arranged for interval, and in two adjacent wheel discs, the index dial positioned at upside
Diameter be greater than the diameter of the index dial positioned at downside, corresponding its pivot center arranged for interval of lower end surface Shangrao in wheel disc
Multiple index holes, and the index hole being located on the index dial of upside is arranged in except the outer peripheral surface of the index dial of downside, together
When each index dial on index hole misplace arrangement.The regulating arm that horizontal direction overhangs is set on the side wall of positioning tube, is adjusted
The locating part that the projecting end setting of arm extends up and down, regulating arm are oriented to along the radial level of positioning tube on the side wall of positioning tube and move
It is dynamic, to adjust the position of locating part, to be adapted to different index dials.
Certainly, in other embodiments, index dial can only be arranged one, and multiple groups have can be set in corresponding index hole,
Respectively correspond different types of impeller-type；In other embodiments, locating part can be directly disposed as guide-pin type structure；It adjusts
