AI Technical Summary
Traditional crankshaft deep oil hole machining equipment is highly dependent on conventional equipment. Ordinary equipment lacks a built-in rotary clamping mechanism, making it difficult to perform multi-angle positioning machining. Existing fixed clamps are cumbersome to manually lock, cannot adapt to crankshafts of different lengths, and frequent adjustments can easily damage the crankshaft.
The cylinder-driven clamping system, combined with arc-shaped clamping blocks and a sliding adjustment structure, achieves stable clamping of the crankshaft. The base plate is rotated by a rotating motor to achieve multi-angle machining. With sliding clamping and translation functions, it can adapt to different crankshaft length and angle requirements.
The high-efficiency machining of deep oil holes at multiple angles was achieved on a conventional drilling machine, reducing equipment costs, improving clamping efficiency and positioning accuracy, and avoiding damage to the crankshaft surface.
