Example Embodiment
[0057] Embodiment 1, a method for processing a high-precision frame for large helicopter assembly tooling, including the following steps: S1, steel pipe blanking, lofting, and processing to welding size;
[0058] S2, milling the welding groove, according to the groove around the groove 30 degrees and 10mm grooves, that is, the groove angle is 30 degrees, the length is 10mm, which can ensure uniform welding seam, uniform welding stress, and weld all positions of the frame The deformation range and gap are reduced, and the strength and rigidity of the welded frame without beveling are greatly improved; the base frame, bracket and top frame are welded to form a frame;
[0059] S3, steel plate blanking, steel plate processing, welding steel plate to the frame assembly position;
[0060] S4. The bottom surface of the reference base frame is welded with the reference surface steel plate to obtain an integral frame;
[0061] S5. Artificial aging annealing; put the integral frame in step S4 i...
