Embodiment 1
[0056] Example 1: 7HA.02 intermediate flange processing
[0057] 1), such as Figure 5 As shown, the figure is a cross-sectional view of the entire blank, and the hatched part is the part that needs to be processed and removed. Thickness of the turning workpiece: according to the requirements, the end face of one side of the rough and finish turning is finished, then turn over, place the turned plane on the contour pad, and align the workpiece, the total height of the rough and finish turning is 64.81±0.5 (front part of the middle flange) , The overall height of the finished car is 61.17±0.5 (rear of the middle flange).
[0058] 2), such as Figure 6 As shown in the figure, process the hole position of the connecting hole at the front of the intermediate flange and select the positioning hole. The front part of the intermediate flange is guided as required Connecting hole position, mark X The pin holes are machined as positioning holes. Or, the rear part of the interme...
