A moving mechanism 3 extending to the outside is arranged inside the frame 1, and a grinding mechanism 4 for deburring the steel pipe body is arranged on the top of the frame 1. The moving mechanism 3 includes a first sprocket 31 rotatably connected to the inside of the frame 1, a forward and reverse motor 32 fixedly installed inside the frame 1, and a rotating shaft 34 rotatably connected to the inside of the frame 1.

A connecting rod 39 extending to the outside of the frame 1 is fixedly connected to the top of the connecting seat 38.

[0026] The forward and reverse motor 32 is started by the controller 6, and the forward and reverse motor 32 drives the transmission gear 33 to rotate. The transmission gear 33 rotates and engages to drive the driven gear 35, the rotating shaft 34 and the second sprocket 36 to rotate. The second sprocket 36 rotates and engages to drive the chain 37 for transmission. The chain 37 drives the connecting seat 38 and the connecting rod 39 to move linearly left and right, so as to grind and deburr the steel pipe bodies of different lengths.

[0027] The forward and reverse motor 32 is electrically connected to the controller 6, and a bearing adapted to the rotating shaft 34 is fixedly installed inside the frame 1. By providing the bearing, the stability of the rotating shaft 34 during rotation is improved.

[0028] Specifically, a moving opening adapted to the connecting rod 39 is provided inside the frame 1 , and the outer diameter of the connecting rod 39 is adapted to the inner diameter of the moving opening.

[0029] In this embodiment, the grinding mechanism 4 includes a mounting plate 41 fixedly connected to the top of the connecting rod 39, a mounting sleeve 42 is fixedly connected to the top of the mounting plate 41, two hydraulic cylinders 43 are fixedly installed inside the mounting sleeve 42, and connecting plates 44 are fixedly connected to the output ends of the two hydraulic cylinders 43, and grinding plates 45 are fixedly connected to the opposite sides of the two connecting plates 44.

[0030] The two hydraulic cylinders 43 are symmetrically distributed inside the mounting sleeve 42, and both hydraulic cylinders 43 are electrically connected to the controller 6.

[0036] When in use, the controller 6 is used to start the extension and retraction of the two electric push rods 54, which drive the clamp 55 to move up and down to clamp and fix the steel pipe bodies of different sizes. Then, the controller 6 is used to start the reduction motor 51, which drives the rotating shaft 52 to rotate. The rotation of the rotating shaft 52 drives the fixed frame 53 to rotate, thereby turning the steel pipe body over. By setting the limit rod 56 and the annular slide groove, the fixed frame 53 drives the steel pipe body to turn stably. When deburring and grinding the steel pipe body, the hydraulic cylinder is started by the controller 6. 43 is extended and retracted, and the hydraulic cylinder 43 is extended and retracted to drive the connecting plate 44 and the grinding plate 45 to move left and right, and is adjusted according to the steel pipe bodies of different sizes.
