【摘要】 为实现直径为1 016mm的螺旋缝焊管生产过程中钢管截面形状和尺寸的在线测量,进行了测量系统的机械机构设计与研制。系统设计过程中提出一种独特的同步带传动方式实现了轨道半径为750mm的高精度圆周运动。采用该传动方式使得传动机构尺寸小巧、运动平稳。同时,为防止运动小车所带电缆对工艺过程的干扰,还设计了一种连杆折叠式电缆收放机构,实现小车供电及信号电缆的自由收放。经长时间运行试验,结果证明机构运行可靠,可以满足测量系统要求。更多还原

【Abstract】 The shape and size of cross profile are important parameters for spiral weld steel pipe(SWSP) during its production.A real-time measuring system was developed to measure the size and shape of 1 016 mm diameter SWSP.The mechanism uses a synchronous belt drive for precision movement along a 750 mm radius circular rail.The device is rather small and very stable.In addition,a cable pulling-pushing unit was designed which prevents the cable from interfering with the pipe forming process.Tests show that the system is stable and reliable.更多还原
