High-precision control system for loop chain processing

The invention discloses a high-precision control system for loop chain processing, which comprises procedures of resetting after bending in place and jacking a ring, and is characterized in that a procedure of resetting backwards and then jacking the ring forwards is added before two roller arms are bent forwards in place and enter the ring jacking procedure, so that the stroke of an oil cylinder is manually prolonged; and therefore, it is guaranteed that the stroke switch can accurately control the stroke of the oil cylinder, the positioning accuracy is improved, it is guaranteed that the distance of the ring opening is smaller than 1 mm, and the follow-up welding procedure is facilitated. 本发明公开了一种环链加工用高精度控制系统，包括在弯曲到位后的复位以及顶环的工序，通过在两个滚轮臂向前弯曲到位要进入顶环工序之前，通过增加一个向后复位再向前顶环的工序，人工的延长了油缸的行程，从而保证行程开关能够准确的控制油缸的行程，以提升定位的准确性，保证环口的距离小于1mm，以便于后续的焊接工序。
