摘　　要：为了实现拖拉机驱动轮轴的自动化装配,提出了自锁螺栓拧紧装配模糊预估的控制方法。根据螺栓拧紧特性对预紧力、扭矩和角度进行预估,用嵌入式装配控制器对拖拉机驱动轮轴总成装配中的自锁螺栓进行拧紧控制,结合光纤传感检测和机械设计技术进行锁片定位装置及其辅助装置的设计。智能化模糊控制算法的运用,完成了对驱动轮轴总成的轴向预紧力、自锁螺栓的扭矩及角度定位多变量目标的模糊智能控制。经实际生产验证,该系统解决了带有锁片定位功能的自锁螺栓装配问题,并且系统具有很高的预测准确率,提高了生产效率和产品质量。With the realization automation assembly for the tractor of driving wheel axle, the control method of fuzzy predictionwas proposed for self-locking bolt tightening assembly. According to the bolt tightening characteristic, the clamping force, torque and angle were predicted, and the self-locking bolt tightening process for the tractor of driving wheel axle assembly were controlled by using the embedded assembly controller. Moreover, the positioning device of lock blade and assist device were designed with combining the technology of fiber optical sensor detection and mechanical design. By the application of intelligent fuzzy control arithmetic, the multivariable target fuzzy intelligent control for axial pre-tightening force, self-locking bolt tightening torque and angle position of driving wheel axle were achieved. Verified by the actual production process, a self-locking bolt assembly question with the function of lock blade positioning was resolved. It had higher prediction accuracy and improved the assembling quality and efficiency.
