全自动铆接机刺铆压扁机构的凸轮是影响铝电解电容器生产质量的关键零件。通过仿真软件对其三维模型进行运动仿真,发现原有凸轮运动性能符合二次多项式规律,其产生的振动与冲击对产品加工质量有很大影响。基于五次多项式,对该机构进行了改进,改变了机构中凸轮摆杆从动件的运动规律,实验表明刺铆压扁机构工作平稳性提高,加工出的铝电解电容质量得到明显改善。 Automatic riveting machine riveting flattening cam mechanism is the impact of aluminum electrolytic capacitor production quality of key components. The simulation of the three-dimensional model through the simulation software found that the original cam performance consistent with quadratic polynomial law, the vibration and impact generated by the product processing quality has a great impact. Based on the fifth-order polynomial, the mechanism was improved to change the movement law of the cam pendulum follower in the mechanism. Experiments show that the work stability of the carabiner flattening mechanism is improved and the quality of the processed aluminum electrolytic capacitor is obviously improved.
