It should be understood that these descriptions are exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0026] As Figures 1-9 shown, an auxiliary device for rust removal of finished steel pipes proposed by the present utility model includes a pair of grinding assemblies 1 arranged crosswise and movably connected through a connecting limit shaft 2, and at the top of the grinding assemblies 1, a movable connection is achieved through an adjusting telescopic electric cylinder 3;

[0027] The grinding assembly 1 is composed of a mounting shell 10. Inside the mounting shell 10, a grinding roller 14 is movably arranged by relying on a pair of bearing seats 13. On one side of the mounting shell 10, there is a mounting bracket 11 which covers the outside of one of the bearing seats 13. One end of the grinding roller 14 is connected to the transmission end of a motor 15, and the motor 15 is installed on the mounting bracket 11. An adjusting rod 12 is arranged on the side surface of the mounting shell 10. At the top of the adjusting rod 12, a "U"-shaped connecting piece 16 is arranged, and a connecting shaft 18 is arranged inside it. The two adjusting rods 12 are connected through a connecting limit shaft 2 in the middle, and a first handle 17 is arranged on the side surface at the top of the adjusting rod 12;

[0028] At the tail of the adjusting telescopic electric cylinder 3, there is a connecting piece one 30, and at the top of the telescopic rod, there is a connecting piece two 31. The connecting piece one 30 and the connecting piece two 31 are respectively movably connected to the connecting shafts 18 at the tops of the two grinding assemblies 1;

[0029] The power supply component 4 includes a clamping kit 40 sleeved on the adjustable telescopic cylinder 3, the bottom of which is clamped on the adjustable telescopic cylinder 3 by several bolt groups 41, and a battery compartment 42 is provided at the top; a slot 45 is opened downward at the top of the battery compartment 42, a baffle 46 is movably inserted in the slot 45, a connection port 47 is opened on one side, a connection hole 48 is opened at the tail, and a power supply battery 44 is arranged inside; two motors 15 are respectively electrically connected to the power supply battery 44 through a connecting wire one 5, the adjustable telescopic cylinder 3 is electrically connected to the power supply battery 44 through a connecting wire two 6, and a second handle 43 is arranged at the top of the battery compartment 42.

[0030] When in use, first, the baffle 46 needs to be opened, and then the power supply battery 44 is steadily placed into the battery compartment 42.
