Abstract

The utility model relates to the technical field of expanding devices, in particular to a seamless steel pipe port expanding device for a hydraulic pipeline, which comprises a bottom plate, a base column cylinder is arranged in the middle of the top of the bottom plate, a rotating rod is arranged in the middle of the inside of the base column cylinder, and a driving bevel gear is sleeved on the outer wall of the lower side of the rotating rod. A rotating sleeve seat is arranged on the outer wall of the rotating rod and located above the driving bevel gear, threaded rods are evenly arranged on the outer wall of the rotating sleeve seat, the outer walls of the threaded rods are sleeved with driven bevel gears, the outer walls of the threaded rods are sleeved with ejector rods, the outer sides of the driven bevel gears are sleeved with diameter expanding rings, and the diameter expanding rings are arranged on the outer sides of the ejector rods. A motor is installed at the bottom of the bottom plate and corresponds to the rotating rod, through the arrangement of the rotating rod, the driving bevel gear, the rotating sleeve base, the threaded rod, the driven bevel gear, the ejector rod and the diameter expanding ring, the motor can open the port of the seamless steel pipe for the hydraulic pipeline through linkage, and therefore the purpose of diameter expanding of the port of the seamless steel pipe can be achieved.
