[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] In this technical solution, a deburring device for the inner wall of a steel pipe includes a base plate 1, four support rods 2 and a support plate 3. The four support rods 2 are respectively installed at the four corners of the upper end of the base plate 1. The support plate 3 is movably fitted onto the upper end of the four support rods 2. An electric push rod 4 is installed between the base plate 1 and the support plate 3. A driving structure is provided at the center of the upper end of the support plate 3. The driving structure includes a mounting plate 5, a dual drive motor 6, two first gears 7, a first bearing plate 8, a drive sleeve 9 and two second gears 10.

[0026] Mounting plate 5 is fixedly installed at the center of the upper end of support plate 3. Dual drive motor 6 is embedded in the center of mounting plate 5. Two first gears 7 are respectively installed on the drive ends of the dual drive motor 6 on both sides. First bearing plate 8 is fixedly installed at the upper end of mounting plate 5. Drive sleeve 9 is embedded in first bearing plate 8. Two second gears 10 are respectively installed on both sides of drive sleeve 9 and mesh with the two first gears 7 respectively.

[0027] In this technical solution, when grinding the inner wall of the steel pipe, the operator first drives the electric push rod 4 between the base plate 1 and the support plate 3 according to the center height of the steel pipe, changing the position of the support plate 3 on the upper end of the four support rods 2. Then, one end of the grinding component is embedded in the drive sleeve 9 and the rotating support structure, and the grinding component is aligned with the center of the steel pipe by electric push. Then, the dual drive motor 6 in the mounting plate 5 is driven. Under the meshing action of the two first gears 7 and the two second gears 10 on both sides of the drive sleeve 9, the drive sleeve 9 rotates in the first bearing plate 8, driving the grinding component. Then, the operator pushes the grinding component, so that the grinding component moves along the axis in the drive sleeve 9, thereby achieving the purpose of grinding the inner wall of the steel pipe.

[0028] In some technical solutions, reference Figure 1 The upper end of the support plate 3 is provided with a rotating support structure on both sides. The rotating support structure includes two auxiliary plates 11, two second bearing plates 12 and two auxiliary sleeves 13.

[0029] Two auxiliary plates 11 are respectively installed on both sides of the upper end of the support plate 3, two second bearing plates 12 are respectively installed on the upper ends of the two auxiliary plates 11, and two auxiliary sleeves 13 are respectively embedded in the two second bearing plates 12.

[0030] In this technical solution, when the grinding assembly rotates, the second bearing plate 12 at the upper end of the auxiliary plate 11 ensures the rotation effect of the auxiliary sleeve 13, and the auxiliary sleeve 13 provides rotational support for the grinding assembly. At the same time, the grinding assembly can move axially within the auxiliary sleeve 13.

[0031] In some technical solutions, reference Figure 1 A grinding assembly is movably installed in the drive sleeve 9 and the two auxiliary sleeves 13. The grinding assembly includes a drive rod 14, a connecting flange 15, and a grinding disc 16.

[0032] The drive rod 14 is movably fitted into the drive sleeve 9 and the two auxiliary sleeves 13. The connecting flange 15 is installed at one end of the drive rod 14, and the grinding disc 16 is installed at one end of the connecting flange 15.

[0033] In this technical solution, when grinding the inner wall of the steel pipe, the drive rod 14 is embedded in the drive sleeve 9 and two auxiliary sleeves 13. Then, according to the inner diameter of the steel pipe, a grinding disc 16 of a specified size is selected, and the grinding disc 16 is connected to one end of the drive rod 14 through the connecting flange 15. During the grinding process, the drive sleeve 9 drives the drive rod 14 to rotate at a constant speed, and the grinding disc 16 at one end of the drive rod 14 grinds the inner wall of the steel pipe.

[0034] In some technical solutions, reference Figure 1The drive sleeve 9 is a hexagonal drive sleeve 9, the auxiliary sleeve 13 is a hexagonal auxiliary sleeve 13, and the drive rod 14 is a hexagonal drive rod 14. The outer diameter of the drive rod 14 is slightly smaller than the inner diameter of the drive sleeve 9 and the two auxiliary sleeves 13.

[0035] Working principle:

[0036] When grinding the inner wall of the steel pipe, the operator first drives the electric push rod 4 between the base plate 1 and the support plate 3 according to the center height of the steel pipe, changing the position of the support plate 3 on the upper end of the four support rods 2. Then, the drive rod 14 is embedded into the drive sleeve 9 and the two auxiliary sleeves 13. Then, according to the inner diameter of the steel pipe, the specified grinding disc 16 is selected, and the grinding disc 16 is connected to one end of the drive rod 14 through the connecting flange 15. The grinding assembly is then electrically pushed to align with the center of the steel pipe. Then, the dual drive motor 6 in the mounting plate 5 is driven, and the two first gears 7 on both sides of the drive sleeve 9... The meshing action of the two second gears 10 causes the drive sleeve 9 to rotate within the first bearing plate 8. The drive sleeve 9 drives the drive rod 14 to rotate at a constant speed. The grinding disc 16 at one end of the drive rod 14 grinds the inner wall of the steel pipe. The second bearing plate 12 at the upper end of the auxiliary plate 11 ensures the rotation effect of the auxiliary sleeve 13. The auxiliary sleeve 13 provides rotational support for the grinding assembly. At the same time, the grinding assembly can move axially within the auxiliary sleeve 13. Then, the operator pushes the grinding assembly to move along the axis within the drive sleeve 9, thus achieving the purpose of grinding the inner wall of the steel pipe.
