[0002] The base of some servo mechanisms in the prior art is the key component of the servo mechanism. The base is generally a complex structure with multiple surfaces. The blank of the base is a forged aluminum cold-pressed part. The processing of these oil passage deep holes has always been a difficult problem in the processing and manufacturing of the base of the servo mechanism.
The current production method is to use ordinary milling machines to process each deep hole by repeatedly adjusting the position and angle of the base. The deep holes of the oil passage on the side of general milling are positioned by the shape, while the small oil passage holes on the bottom are drilled by the clamp machine. Die positioning processing, due to the inconsistency of the positioning datum, the intersection and dislocation of the deep hole of the side oil passage and the small hole on the bottom surface often occur during the processing, and the processing quality is difficult to guarantee, which has become a common problem affecting the quality
