As the improvement to this technology, dividing plate positioning tool comprises lower margin and is arranged on the column that on lower margin, two are vertically arranged; The dividing plate positioning boss that arrange along level paired in the same side of two root posts, on often pair of dividing plate positioning boss, the height on edge is contour with the lower surface of corresponding dividing plate.
This improvement, adds the stability of dividing plate positioning tool, the more important thing is, the effect of Appropriate application gravity, only bulkhead bracket need be located on dividing plate positioning boss and can carry out subsequent job, and operation is convenient.
As the further improvement to this technology, blade positioning tool at least comprise two panels identical, the location-plate that be arranged in parallel, the upper surface of upper location-plate is not more than the distance of lower surface apart from the upper surface of lower clapboard of upper spacer in adjacent two dividing plates apart from the distance of the lower surface of lower location-plate; Location-plate positive stop lug boss is had for limiting the position of location-plate in dividing plate radial direction in the arranged outside of location-plate; Location-plate there is blade positioning boss, the angle of the locating surface of adjacent two blade positioning boss is equal with the angle of adjacent two blades, the locating surface of each blade positioning boss is equal apart from the distance of rotor axis line with blade lower surface apart from the distance of rotor axis line, in two adjacent blade positioning boss, the locating surface of a blade positioning boss is perpendicular to the side of another blade positioning boss.
Utilize above-mentioned blade positioning tool, blade is circumferentially evenly located, after one-time positioning terminates, utilize at least two panels blade after welding as benchmark moving blade positioning tool, carry out follow-up blade positioning welding operation, accurate positioning, easy to operate.

Detailed description of the invention
Below in conjunction with accompanying drawing, this technology is described further:
Shown in Fig. 1, Fig. 2, Fig. 3, on the whole, this powder concentrator large-diameter rotor positioning fixture for forming, a set of large-diameter rotor positioning fixture for forming is made up of at least two dividing plate positioning tools and at least one blade positioning tool 6; Blade positioning tool 6 moves along the outer of dividing plate 4 and is arranged between adjacent two dividing plates 4; Dividing plate positioning tool is by dividing plate 4 equidistant separation, horizontal location; Blade positioning tool 4 is by blade 5 equidistant separation, vertically locate.
Specifically:
The dividing plate diameter of powder concentrator large-diameter rotor is comparatively large, and because sheet material dispatches from the factory the restriction of specification, full wafer dividing plate is welded by multi-disc split.
Dividing plate positioning tool comprises lower margin 1 and is arranged on the column 2 that on lower margin 1, two are vertically arranged; The dividing plate positioning boss 3 that arrange along level paired in the same side of two root posts 2, on often pair of dividing plate positioning boss 3, the height on edge is contour with the lower surface of corresponding dividing plate 4.
Dividing plate positioning tool is welded by wire rod, section bar and sheet material.
Lower margin 1 provides basis for column 2 and ensures the stability of dividing plate positioning tool.
Again see shown in Fig. 4, Fig. 5, Fig. 6, blade positioning tool 6 at least comprise two panels identical, the location-plate 601 that be arranged in parallel, the upper surface of upper location-plate is not more than the distance of lower surface apart from the upper surface of lower clapboard of upper spacer in adjacent two dividing plates, to ensure that blade positioning tool 6 is flexibly mobile between adjacent two dividing plates 4 apart from the distance of the lower surface of lower location-plate.
There is location-plate positive stop lug boss 602 for limiting the position of location-plate 601 in dividing plate 4 radial direction in the arranged outside of location-plate 6, as can be seen from the figure, being also provided with two location-plate columns 603 at the two ends of two panels location-plate 601 and two panels location-plate 601 is connected firmly.
On location-plate, 601 have blade positioning boss 606, the angle of the locating surface 604 of adjacent two blade positioning boss 606 is equal with the design angle of adjacent two blades 5, the locating surface 604 of each blade positioning boss 606 is equal apart from the distance of rotor axis line 7 with blade 5 lower surface apart from the distance of rotor axis line 7, in two adjacent blade positioning boss 606, the locating surface 604 of a blade positioning boss 606 is perpendicular to the side 605 of another blade positioning boss 606.
During use, dividing plate adopts accurate blanking to ensure the uniformity of every block dividing plate monomer, now adopts plasma blanking; Workbench marks concentric circles; According to concentric circles, dividing plate docking is welded into monoblock, corrects flatness.Utilize dividing plate frock by dividing plate Hierarchical Location.Utilize blade frock circumferentially evenly to be located by blade, after one-time positioning terminates, utilize at least two panels blade after welding as benchmark moving blade positioning tool, carry out follow-up blade positioning welding operation.
The beneficial effect of this technology is:
To usually make the operation of powder concentrator large-diameter rotor: blanking---shaping---welding---machined---blance test; Be reduced to: blanking---shaping---welding, save machined and balance the test procedure, reduce manufacturing cost.
Accurate positioning, easy to operate.
