Grinding device used for removing burrs at cut openings of steel pipes

The invention discloses a grinding device used for removing burrs at cut openings of steel pipes. The grinding device comprises a bottom plate, guide grooves are formed in the bottom plate, guide rods are arranged in the guide grooves, springs are arranged on the outer sides of the guide rods, the outer sides of the guide rods are slidably connected with guide blocks in a sleeved manner, the guide blocks are slidably connected with the guide grooves, clamping sleeves are fixedly connected to the guide blocks, the clamping sleeves are fixedly connected with protruding blocks, the protruding blocks are in contact with a steel pipe, the steel pipe is in contact with the bottom plate, and the bottom plate is fixedly connected with a fixed seat. By designing the clamping sleeves, the protruding blocks and the steel pipe to be in contact, a clamping and positioning effect can be achieved on the steel pipe, the steel pipe can be prevented from moving in the horizontal direction, and therefore the situation that the steel pipe deviates to affect the grinding effect during grinding is avoided, the distance between the two clamping sleeves can be adjusted, and therefore the device can grind steel pipes with different diameters.
