Specific implementation mode
As shown in Figure 1, at the initial stage of development, traditional positioning method is used, casting dimension is detected with blade profile center A and method
Blue bottom surface B is primary standard, and flange back C is auxiliary base, past in process at the scene since A benchmark are Special-Shaped Surface center
Toward there is position inaccurate, there is dimensional discrepancy, Mechanical processing of casting, welding sequence, inefficiency could be completed by needing repeatedly to adjust.
Especially when carrying out welding support plate, blade profile center A Reference Transformings to outer profile D, the more inaccurate of benchmark is caused.Especially
It is asymmetric for part support plate blade profile, such benchmark is just more undesirable to be.
As shown in Fig. 2, tri- positioning convex platforms of A1, A2, A3 are arranged in the one side of blade, tri- positioning convex platforms of A1, A2, A3 are with three
Point location mode arranges that two positioning convex platforms of A1, A2 are located at the top in blade face, and A3 positioning convex platforms are located at the lower part in blade face.
Positioning convex platform is arranged in the side installation side top selective positioning point B1 of blade, and side lower part selective positioning point B2 is installed in the side of blade
Positioning convex platform is set.In addition, positioning convex platform is arranged in flange back selective positioning point C1.
The improved casing support plate positioning method of the present invention realizes leaf using tri- positioning convex platforms of A1, A2, A3 as primary standard
Type positions；It is auxiliary anchor point with positioning convex platform B1, B2, positions axial height dimension；It is fixed by auxiliary base of positioning convex platform C1
Position positions circumferential size.To realize accurate quickly detection and positioning and clamping.
It is as follows that size detection, mechanical processing process are carried out according to six point location modes shown in Fig. 2：
