汽车制动主缸活塞部件拧紧机研制

Development of Tightening Machine for Piston Parts of Main Brake Cylinder of Automobile

针对传统气动扳手冲击大、拧紧力矩不稳定、手动操作劳动强度大以及活塞部件装配过程中弹簧与活塞易剐蹭的问题,研制一种汽车制动主缸活塞部件拧紧工装设备。设备结构为双工位形式,左工位使用伺服电机搭配转矩传感器实现活塞部件的装配拧紧及拧紧力矩检测,与此同时,右工位应用位移传感器技术对活塞总成的半高尺寸进行检测,并实时把拧紧力矩和半高尺寸值显示在操作屏上。该活塞部件拧紧机具有拧紧力矩可观测、效率高、模块化、安全可靠、操作方便等特点,具有较高的应用价值。

In view of the problems of large impact,unstable tightening torque,high labor intensity and easy rubbing between spring and piston existing in the operafing process of the traditional pneumatic wrench,the equipment for tightening piston parts of automobile brake main cylinder is developed.Its structure is in the form of deplex position.The assembly tightening and tightening torque of the piston parts are detected in the left station,and the half-height size of the piston parts is tested in the right station.The piston component tightening machine is characteristic of observable tightening torque,high efficiency,modularization,safety and reliability,convenient operation and so on.
