The utility model relates to the technical field of steel
pipe positioning and perforating, in particular to a seamless steel
pipe positioning and perforating device which comprises a
workbench body, two first moving frames are arranged at the top of the
workbench body and connected through a second
moving frame, and a third
moving frame is arranged on the outer side of the second
moving frame. A perforating shaft is arranged at the end, away from the second moving frame, of the third moving frame, multiple sets of connecting bases are arranged at the top of the
workbench body and at the ends, close to each other, of the two sets of first moving frames, and positioning and fixing assemblies are arranged at the ends, close to each other, of the multiple sets of connecting bases. The positioning and fixing
assembly is used for positioning and fixing steel pipes of different specifications, the positioning and fixing
assembly is composed of a moving shell, a
rotating disc, an arc-shaped groove, a moving rod, a limiting rod and a driving screw rod, and compared with an existing perforating device, the overall practicability of the perforating device can be improved through the design.
