摘　　要：针对钢管倒棱对中夹持精度较低的问题,设计研制了一种基于双夹紧液压缸及相应连杆机构的对中夹紧系统,并成功将该装置应用于钢管夹持倒棱加工中。该系统通过双夹紧液压缸的相向运动和相互联动的夹瓦对中机构,实现对工件的对中夹紧。该系统机构简单易实现,且通过机械连接强制保证两只液压缸同步,可有效减小由于工件夹紧部位外形的偏差引起的中心偏离,从而提高夹紧时的对中精度。实际应用结果表明,该系统可有效提高倒棱钢管对中夹紧的效率和精度。Aiming at the problem of poor precision in the centering clamping of pipe chamfering process, a centering clamping system based on double hydraulic cylinder and corresponding link mechanism was designed and successfully applied in the clamping and chamfering process of steel pipes. Centering and clamping of workpiece were achieved through face- to- face motion of double cylinders and interaction of the clamping centering mechanism.Simple and easy to operate, the system can effectively reduce the off- centering caused by shape deviation of clamp position and ensure the synchronization of cylinders through mechanical connection, thus improve clamping precision. Actual application results have showed that the system can effectively enhance the efficiency and precision of centering and clamping during steel pipe chamfering process.
