A kind of positioning assembly method of rotor magnet yoke vertical rib of vertical unit comprises the welding of stud and fanning strip, is characterized in: adopt stud one point location, the yoke sheet is done the method that model is accurately looked for string, and specifically assembling process is,
1) at first with centerbody in the rotor field spider and fanning strip welding back leveling, the rotor field spider pad rises and keeps flat, water detection flat; Folded sign indicating number magnet yoke blanking sheet supports good and leveling, guarantees that the circle at magnet yoke blanking sheet place is concentric with rotor field spider;
2) magnet yoke key is squeezed in the groove of stud, in the groove of fanning strip, the dove tail end of key inserts in the groove of magnet yoke blanking sheet about then simultaneously stud, magnet yoke key being inserted; The groove of magnet yoke blanking sheet is determined the position of its stud by magnet yoke key;
3) make model in the rotor field spider upper end with magnet yoke blanking sheet and come accurately to locate, guarantee that the groove string distance on the stud equates to stud;
4) after the stud position is determined, it is clamped, again stud and fanning strip are welded with frock.
The positioning assembly method of rotor magnet yoke vertical rib of vertical unit of the present invention can also adopt following technical measures:
The positioning assembly method of described rotor magnet yoke vertical rib of vertical unit is characterized in: folded sign indicating number magnet yoke blanking sheet is the high magnet yoke blanking sheet of 90-110m.
The positioning assembly method of described rotor magnet yoke vertical rib of vertical unit is characterized in: the circle at assurance magnet yoke blanking sheet place is concentric with rotor field spider to be the method that adopts the distribution circle of surveying circle frame and dial gauge detection magnet yoke blanking sheet place.
The positioning assembly method of described rotor magnet yoke vertical rib of vertical unit, be characterized in: make model in the rotor field spider upper end with magnet yoke blanking sheet and come accurately to locate to stud, be that magnet yoke key is inserted in the magnet yoke blanking sheet model groove, first stud vertical adjustment is straight, and then other stud is also located under the effect of yoke model thereupon.
Advantage that the present invention has and good effect:
The positioning assembly method of rotor magnet yoke vertical rib of vertical unit, owing to adopt brand-new technology scheme of the present invention, model when utilizing magnet yoke blanking sheet to put stud, omitted the duplication of labour with the measurer repeated measurement, measure error and apparent value error have been eliminated, greatly reduced labour intensity, improved production efficiency, for the pendulum weldering of the rotor stud of large-scale mixed unit provides a saving of labor, laborsaving, the process being convenient to operate.
