[0019] Example: Figures 1-6 As shown, this utility model provides a high-efficiency polishing machine for the inner wall of steel pipes, including a base 1. The top of the base 1 is provided with two symmetrically distributed first rotating shafts 11 and two support blocks 12. The support block 12 on the left side is fixedly connected to the base 1. The outer side of each of the two first rotating shafts 11 is provided with several rotating wheels 13. The top of the first rotating shaft 11 is provided with two moving blocks 14. The bottom end of each moving block 14 is fixedly installed with an electric push rod 15. The driving end of the electric push rod 15 is fixedly installed with a lower moving plate 17. The bottom end of each lower moving plate 17 and the top end of the support block 12 are rotatably installed with a pressure wheel 18 through several sets of ring-shaped fixed blocks. The two first rotating shafts 11 are connected by a synchronous belt drive. The top of the base 1 is provided with a first screw 2 and two limiting blocks 21. The outer side of the first screw 2 is threadedly connected with a T-shaped block 22. The T-shaped block 22 is slidably connected to the limiting block 21.

[0020] Both movable blocks 14 have a first circular groove 10 through their middle sections, and a first screw 2 passes through the first circular groove 10. A second rotating shaft 23 is rotatably connected to the bottom of the T-shaped block 22. A grinding wheel 24 is fixedly installed on the side of the second rotating shaft 23 near the movable block 14, and a drive motor 25 is provided on the side of the second rotating shaft 23 away from the grinding wheel 24. The first screw 2 is driven by a stepper motor, and the drive end is fixedly connected to the first screw 2. The first rotating shaft 11 is driven by a motor, and the motor is fixedly connected to one of the first rotating shafts 11. The synchronous belt is a toothed synchronous belt drive, which is used in conjunction with a toothed pulley and a toothed transmission belt. It can also be driven by a chain and sprocket, or other transmission methods can be selected.

[0021] The right-side movable block 14 is slidably connected to the limiting block 21, and both sides of the movable block 14 are threaded with second screws 3. The side of the second screw 3 closest to the limiting block 21 is fixedly installed with a first pressing plate 31. The inner walls of the right-side movable block 14 are provided with second circular grooves 32 that cooperate with the first pressing plate 31. The side of the right-side support block 12 away from the T-shaped block 22 is fixedly installed with a connecting plate 33. The middle of the connecting plate 33 is threaded with a third screw 34. The bottom end of the third screw 34 is fixedly installed with a second pressing plate 35. The upper surface of the base 1 is fixedly installed with a slide rail 36. The right-side movable block 14 is slidably connected to the slide rail 36. The second screw 3 and the third screw 34 are both rotated by a plum blossom-shaped handle, and the plum blossom-shaped handle is fixedly connected to the second screw 3 and the third screw 34.

[0022] Several annularly distributed locking blocks 4 are fixedly installed on the outside of the two first rotating shafts 11. Each rotating wheel 13 has a slot 41 on its inner wall that works with the locking blocks 4. By setting the locking blocks 4 and the slots 41, the rotating wheel 13 can be adjusted at will on the first rotating shaft 11, and the rotating wheel 13 can avoid affecting the movement of the support block 12 located on the right side.

[0023] The diameter of the first circular groove 10 is larger than the diameter of the first screw 2, so that the first screw 2 can rotate more smoothly in the first circular groove 10 opened in the moving block 14, and the moving block 14 and the first screw 2 do not affect each other.

[0024] The two limiting blocks 21 are symmetrically distributed, which makes the T-shaped block 22 more stable when it moves.

[0025] The first screw 2 has support plates 5 rotatably mounted on both ends. The support plates 5 are fixedly connected to the base 1. The two ends of the limiting block 21 are fixedly connected to the support plates 5. The limiting block 21 passes through the left moving block 14. By setting the support plates 5, the first screw 2 and the limiting block 21 are supported, so that the first screw 2 and the limiting block 21 can be used normally. The stepper motor is fixed on one of the support plates 5.

[0026] An L-shaped block is fixedly installed on the side of the T-shaped block 22 near the drive motor 25. The L-shaped block is fixedly connected to the drive motor 25. By setting the L-shaped block, the drive motor 25 is supported. At the same time, it avoids the drive motor 25 from directly contacting one of the support plates 5 when the drive motor 25 moves with the first screw 2 towards the moving block 14, which would cause damage to the drive motor 25 and affect normal use.

[0027] The first rotating shaft 11 is rotatably sleeved with a fixing seat 6 close to one end of the T-shaped block 22, the fixing seat 6 is fixedly connected with the base 1, and the other end of the first rotating shaft 11 rotatably penetrates through the supporting plate 5, the first rotating shaft 11 is supported by the fixing seat 6 and the supporting plate 5, so that the first rotating shaft 11 can be normally used, the rotating wheel 13 is driven to rotate, and the pipeline is driven to rotate.

[0028] Working principle: in actual use, one end of the pipeline is attached to the inner side of the supporting plate 5 on the left side and is placed on the pressing wheel 18 on the two supporting blocks 12, then the two electric push rods 15 are started to drive the downward moving plate 17 and the pressing wheel 18 below the downward moving plate 17 to move downward, so that the pressing wheel 18 is attached to the outer wall upper surface of the pipeline, the two ends of the pipeline are pressed, then the forward and reverse rotation of the stepping motor is controlled, the first screw rod 2 is rotated, then the T-shaped block 22 drives the second rotating shaft 23 and the grinding wheel 24 to advance towards the pipeline through the limiting of the limiting block 21, and the grinding wheel 24 is attached to the upper surface of the inner wall of the pipeline and is located at the edge of the pipeline;

[0029] Then the driving motor 25 is started to drive the second rotating shaft 23 and the grinding wheel 24 to rotate, during grinding, the grinding wheel 24 needs to always advance forward until the inner wall of the pipeline attached to the grinding wheel 24 is ground, the motor connected with the first rotating shaft 11 is started to rotate one of the first rotating shafts 11, since the two first rotating shafts 11 are connected through the synchronous belt transmission, the two first rotating shafts 11 rotate at the same time, the corresponding rotating wheel 13 is driven to rotate, so that the pipeline is rotated, the other inner wall of the inner wall of the pipeline is attached to the grinding wheel 24, then the grinding wheel 24 moves back, and then the pipeline is rotated after grinding is completed, and the operation is repeated;

[0030] When different lengths of the pipeline need to be polished, first, the second screw rod 3 is rotated to drive the first pressing disc 31 to rotate, so that the first pressing disc 31 is away from the corresponding limiting block 21, then the moving block 14 on the right side is manually pushed to the direction of the T-shaped block 22, so that the moving block 14 is adjusted to the position of the length suitable for the pipeline, when the suitable position is adjusted, the second screw rod 3 and the first pressing disc 31 are reversely rotated by reversely rotating the wrench, so that the first pressing disc 31 is attached to the corresponding limiting block 21, thereby fixing the moving block 14 on the right side on the limiting block 21;

[0031] After adjustment, the third screw rod 34 is rotated by rotating the star-shaped handle on the third screw rod 34, so that the second pressing disc 35 is driven to rotate and is separated from the slide rail 36, then the right support block 12 is pushed to the opposite direction of the T-shaped block 22, and when the right support block 12 is pushed to the appropriate position, the star-shaped handle on the third screw rod 34 is reversely rotated, so that the third screw rod 34 and the second pressing disc 35 are reversely rotated and are attached to the slide rail 36, thereby fixing the right support block 12 on the slide rail 36;

[0032] When the right moving block 14 and the right support block 12 are adjusted, the right support block 12 can be pushed to the left by rotating the rotating wheel 13.

[0033] Obviously, various modifications and changes can be made to the present application without departing from the spirit and scope of the present application. Therefore, if these modifications and changes belong to the scope of the present application claims and equivalent technologies, the present application also intends to include these modifications and changes.
