AI Technical Summary
Traditional processing methods make it difficult to accurately clamp and position the outlet nozzle of the arc-shaped sidewall of a large cylinder, resulting in insufficient roundness of the hole, large hole diameter error, low processing efficiency, and difficulty in ensuring the smoothness and dimensional accuracy of the hole wall.
A machining device comprising a base plate, a rectangular frame plate, a lifting movable plate, a rotating plate, and a milling cutter holder is adopted. By driving the reciprocating motion of the rectangular frame plate, the circumferential motion of the rotating plate, and the flexible adjustment of the milling cutter holder, the milling cutter feed trajectory can be precisely matched with the curvature of the arc-shaped side wall of the cylinder.
It improves the roundness accuracy and diameter consistency of round holes, enhances processing efficiency, and ensures the smoothness and dimensional accuracy of hole walls.
