The top of the base 1 is slidably connected to a sliding seat 302, and the sliding seat 302 A baffle plate 301 is fixedly connected to the top, and two connecting rods 205 are rotatably connected to the two sides of the baffle plate 301 respectively. A grinding assembly 307 is fixedly connected to the baffle plate 301. In order to improve the grinding quality, the grinding assembly 307 adopts a metal louver grinding wheel; through the setting of the positioning mechanism, the steel pipe is placed close to the positioning plate 201, and the first motor 305 is started to rotate the threaded rod 304, driving the sliding seat 302 to move along the direction of the limit rod 308, driving the baffle plate 301 to approach the positioning plate 201, and the distance between the baffle plate 301 and the positioning plate 201 is shortened, driving the connecting rod 205 to push the positioning plate 201 to move along the direction of the sliding rod 202, and driving the grinding assembly 307 to approach the steel pipe, thereby realizing the positioning of the steel pipe, facilitating the grinding assembly 307 to accurately grind the cut surface of the steel pipe, and avoiding damage to other positions of the steel pipe causing a decrease in the quality of the steel pipe.

[0028] like Figure 1 As shown, in one embodiment, a motor bracket 306 is fixedly connected to the top of the base 1, and a first motor 305 is fixedly connected to one side of the motor bracket 306. In order to facilitate maintenance and replacement, the first motor 305 is fixedly connected to the motor bracket 306 by screwing, and the output end of the first motor 305 is connected to a threaded rod 304 through a coupling, one of which is a fixed block 309 that is rotatably sleeved on the threaded rod 304, and support blocks 303 are fixedly connected to both sides of the sliding seat 302, and one of which is a support block 303 that is screwed on the threaded rod 304; through the setting of the first motor 305, the steel pipe is placed close to the positioning plate 201, and the first motor 305 is started to rotate the threaded rod 304, driving the sliding seat 302 to move along the direction of the limiting rod 308, providing driving force for the connecting rod 205.
