基于PLC的自动化柔性夹具设计
Design of Automatic Flexible Fixture Based on PLC

针对薄壁件高速铣削加工的装夹的变形问题，设计出基于PLC的自动化水平较高、夹紧力可调的夹具，制定了工艺方案、设计了程序流程图以及PLC程序，最后运用有限元对加工件进行受力分析；与传统夹紧方式相比，工件变形量明显减少，提高了夹具的自动化、柔性化程度；经实践证明，该夹具设计合理、运行可靠，值得推广。
Aiming at the problem of clamping deformation in high-speed milling of thin-walled parts, a fixture with high automation level and adjustable clamping force based on PLC is designed. The process plan, program flow chart and PLC program are designed. Finally, the force analysis of the workpiece is carried out by using finite element method. Compared with the traditional clamping method, the deformation of the workpiece is significantly reduced, and the degree of automation and flexibility of the fixture is improved. The practice proves that the fixture is reasonable in design, reliable in operation and worthy of popularization.
