Our rework plan is as follows:1. In the first step, the laser cladding technology is adopted to weld the four large holes at the position shown in the figure, and the thickness of one side is about 0.5mmProcessing experience, this kind of welding on the parts themselves almost does not produce deformation.2. In the second step, the parting surfaces of the upper and lower boxes are milled, and the thickness of one side is about 0.3mm;3. Finally, correct the two sides of the box in place, install the positioning pins, tighten the bolts, re process the four large holes to the drawing requirements, and at the same time, smooth out the assembly datum plane on both sides of the box.
