Spiral welded pipe forming position pipe diameter perimeter monitoring system

The invention discloses a spiral welded pipe forming position pipe diameter perimeter monitoring system which comprises a bottom plate, a horizontal sliding rail, a sliding bottom plate, a horizontaladjusting electric cylinder, a stand column, an mounting frame sliding rail, an mounting frame, a supporting wheel, a center shaft, a calibration disc, an inner frame sliding groove, an up-down adjusting electric cylinder and an inner frame.Sliding rails are fixed to the left and right of the top of the bottom plate. The sliding bottom plate slides in the left-right direction of the sliding railsthrough a bottom horizontal adjusting electric cylinder, stand columns are vertically fixed to the left side and the right side of the top of the sliding bottom plate, vertical mounting frame slidingrails are fixed to the front portions and the rear portions of the stand columns correspondingly, and the front mounting frame and the rear mounting frame slide up and down along the mounting frame sliding rails. Riding wheels are fixed in the middle of the mounting frames; and the calibration disc is placed on the front and rear riding wheels through a central shaft. Alarm is performed if the tolerance range is exceeded, the alarm is fed back to production equipment for adjustment, measurement is rapid and accurate, the high-speed laser range finder mounting plate is provided with the V-shaped positioning pin, and rapid and accurate positioning and mounting can be achieved.
