A touch plate 463 is installed inside the installation groove, and one end of the touch plate 463 is connected to the piston 461 through a touch rod 462. The inner wall of the installation groove is provided with a placement groove that matches the touch plate 463. When in use, when one end of the steel pipe is inserted into the installation groove of the rotating sleeve 42 for installation, the end of the steel pipe also squeezes the touch plate 463 to move it to the inside of the placement groove, and then the movement of the touch plate 463 drives the touch rod 462 to squeeze the piston 461, and then the gas inside the air cylinder 46 is squeezed into the inside of the air bag 465 through the air pipe 464, so that the air bag 465 is inflated and expanded, and then the volume becomes larger, and the grinding head 45 is pushed through the connecting plate 44, so that the grinding head 45 fits the inner side of the cut surface of the steel pipe. When the steel pipe rotates, the grinding effect is realized, which is conducive to a smooth cut surface without burrs.

[0027] The present invention can clamp and fix the steel pipe and drive it to move through the clamping drive component, which is beneficial to the cutting and grinding of the steel pipe. The inner support member can support the edge of the cutting part to improve the cutting accuracy. The installation support assembly can support the steel pipe, which is beneficial to the cutting and grinding of the steel pipe. The support member 33 can be clamped and installed on steel pipes of different diameters. The inner side of the cutting surface can be grinded by the grinding assembly to improve the grinding efficiency. The grinding head 45 is height-adjustable and is also suitable for steel pipes of different diameters, which is beneficial to subsequent welding.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
