Utility model content
Technical problem to be solved in the utility model is for above prior art, provides a kind of francis turbine runner assembling jig, and this fixture can ensure the accurate location of each blade thus guarantee the whole machine balancing of runner and normal use.
The technical scheme that the utility model adopts is:
A kind of francis turbine runner assembling jig, this fixture comprises cup dolly, be fixed on several ⊥ shape locating racks of cup dolly, with the inverted L-shaped adjusting pole of ⊥ shape locating rack quantity Matching, the center of described cup dolly is provided with a manhole for accommodating crown top axis hole jag, described ⊥ shape locating rack is along the circumferential spaced set centered by manhole, the riser of described ⊥ shape locating rack is provided with the groove for clamping inverted L-shaped adjusting pole riser, and the bottom of groove is provided with a strip through hole, described ⊥ shape locating rack and inverted L-shaped adjusting pole are positioned by the adjustment bolt through strip through hole.
This fixture is used for assembling and the just weldering of francis turbine runner, the position of ⊥ shape locating rack and the height of inverted L-shaped adjusting pole opposing circular base is adjusted in advance according to the size of pre-assembled runner, by crown back-off on cup dolly and top axis hole jag is placed in the manhole of cup dolly, lower ring is inverted on the transverse slat of inverted L-shaped adjusting pole, and lower ring position is accurately located by fine setting adjustment bolt, then between crown and lower ring, blade is installed and spot welding, realizes the first assembling of runner.
After adopting above structure, the utility model compared with prior art, has the following advantages: the utility model francis turbine runner assembling jig structure is simple, firmly, practicality, durable in use, the accurate location of crown, lower ring, each blade can be ensured thus guarantee the assembling demand of runner, obtain runner balance and stability performance good, use safety, long service life, and this fixture greatly facilitates the assembly work of francis turbine runner, time saving and energy saving, efficiency of assembling is high.
As preferably, the riser upper vertical of described ⊥ shape locating rack is provided with the caging bolt for propping up lower ring top outer in riser, and the head of described caging bolt is towards inner side.This caging bolt is used for the lower ring in circumference location, makes the location of lower ring more accurate, thus more can guarantee the assembly precision of runner.
As preferably, inside the transverse slat of described ⊥ shape locating rack and be provided with triangle reinforcement between riser; Triangle reinforcement is provided with between the transverse slat of described inverted L-shaped adjusting pole and riser.The structure of triangle reinforcement makes this clamp structure more firm, uses safer, also more can guarantee the assembly precision of runner.
As preferably, outside the transverse slat of described ⊥ shape locating rack and be fixed by bolt between cup dolly.Bolt fastening structure is more firm, uses safer, also more can guarantee the assembly precision of runner.
As preferably, the quantity of described ⊥ shape locating rack is four.This setting makes location between crown, lower ring good, can ensure assembling demand, and can facilitate the installation of blade and first welder's sequence.
