[0003] A Chinese patent with publication number CN215787903U discloses an oil pipe welding fixture for oil pipe cylinder barrel processing, including a support base and a rubber protective layer, the top surface of the support base is provided with a positioning groove, and a limiting column is installed inside the positioning groove, and the limiting column is embedded and fixedly connected with the inner wall of the support base, the limiting column passes through a limiting straight plate, and the limiting straight plate is located inside the positioning groove, a support plate is welded and fixedly installed on the top surface of the limiting straight plate, and the top end of the support plate is sleeved and installed on the outside of the center ring, and an oil pipe clamping plate is installed inside the center ring. The oil pipe welding fixture for processing the oil pipe cylinder barrel, after the staff completes the clamping and fixing work of the oil pipe, can subsequently push the support plate to make the support plate slide and shift smoothly through the limiting straight plate, thereby shifting the oil pipe, which is beneficial to the mutual alignment work and prevents the occurrence of large gaps that affect the subsequent welding processing work. The oil pipe welding fixture for processing the oil pipe cylinder barrel in the application drives the two oil pipe clamping plates to slide through the connecting shaft, but the spacing between the positioning column and the connecting shaft is smaller than the diameter of the oil pipe clamping plate, which affects the adaptability range of the oil pipe diameter.
