一种高效加工曲轴连杆的组合数控铣床
摘要：
本发明公开了一种高效加工曲轴连杆的组合数控铣床，包括床身(1)、A机组(2)、B机组(3)、C机组(4)。本发明采用床身上面设有工作台、AY轨面BY轨面和CY轨面；A机组位于AY轨面上，B机组位于BY轨面上，C机组位于CY轨面上；工作时，连杆坯件固定装夹在工作台上，围绕连杆坯件，A机组加工螺栓孔，B机组加工衬套孔，C机组加工轴瓦合符孔，通过一次性装夹联合切削加工获得连杆整件的技术方案，使曲轴连杆的加工达到了简化工艺、提高效率、降低成本的目的。
摘要（英）：

The invention discloses a combined numerical control milling machine for efficiently processing a crankshaft connecting rod. The machine comprises a machine body (1), a set A (2), a set B (3) and a set C (4). The machine body is provided with a working table, a rail surface AY, a rail surface BY and a rail surface CY; the set A is positioned on the rail surface AY; the set B is positioned on the rail surface BY; the set C is positioned on the rail surface CY; in working, a connecting rod blank is fixed and clamped on the working table; by surrounding the connecting rod blank, the set A processes a bolt hole, the set B processes a bushing hole, and the set C processes a bearing bush matching hole; and through the technical scheme of processing the connecting rod integer by combining once clamping with cutting, the processing of the crankshaft connecting rod achieves the purposes of simplifying the process, improving the efficiency and reducing the cost.
