[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example 1: Please refer to Figure 1 - Figure 8 This embodiment of a metal parts processing grinding and cleaning device includes a base 1 and a column 2. The column 2 is fixedly connected to one top end of the base 1. A sleeve 14 is rotatably connected inside the column 2. A connecting column 13 is movably connected inside the sleeve 14. A fixed plate 3 is fixedly connected to one end of the connecting column 13. A handwheel 4 is provided on one side of the fixed plate 3. A rotating shaft 5 is fixedly connected to one side of the handwheel 4. One end of the rotating shaft 5 passes through the interior of the fixed plate 3. A first gear 6 is fixedly connected to one end of the rotating shaft 5. A second gear 7 is meshed with the bottom of the first gear 6. The inner... The part is machined with multiple movable slots 9. Movable columns 8 are movably connected inside the movable slots 9. A connecting rod 10 is fixedly connected to one end of the movable column 8. A brush 12 is fixedly connected to one end of the connecting rod 10. A first motor 17 is set on one side of the column 2. A third gear 18 is fixedly connected to one end of the first motor 17. A fourth gear 19 is meshed on one side of the third gear 18. The fourth gear 19 is fixedly connected to one end of the sleeve 14. An inner cavity is machined inside the sleeve 14. A hydraulic cylinder 20 is set at one end of the inner cavity. One end of the hydraulic cylinder 20 is fixedly connected to one end of the connecting column 13.

[0031] When it is necessary to polish the inner wall of the metal tube, the brush 12 is placed inside one end of the metal tube, and then the handwheel 4 is turned. The handwheel 4 will drive the rotating shaft 5 to rotate, the rotating shaft 5 will drive the first gear 6 to rotate, the first gear 6 will drive the second gear 7 to rotate, the second gear 7 will drive the movable column 8 to move, the movable column 8 will move along the inside of the movable groove 9, and at the same time the movable column 8 will drive the connecting rod 10 to move, the connecting rod 10 will drive the brush 12 to move, so that the multiple brushes 12 can extend or retract, which is convenient for polishing and cleaning metal tubes with different inner diameters.

[0032] Secondly, after the position of the brush 12 is adjusted, the first motor 17 is started. The first motor 17 will drive the third gear 18 to rotate, the third gear 18 will drive the fourth gear 19 to rotate, the fourth gear 19 will drive the sleeve 14 to rotate, the sleeve 14 will drive the connecting column 13 to rotate, and the connecting column 13 will drive multiple brushes 12 to rotate through the fixed plate 3, thereby facilitating the grinding of the inner wall of the metal tube. At the same time, the hydraulic cylinder 20 is started. The hydraulic cylinder 20 will drive the connecting column 13 to move, and the connecting column 13 will drive the fixed plate 3 and the brushes 12 to move back and forth along the inside of the metal tube, thereby facilitating the grinding and cleaning of the inner wall of the metal tube.

[0033] Furthermore, multiple fixed cylinders 11 are fixedly connected to the other side of the fixed plate 3, and the connecting rod 10 is movably connected inside the fixed cylinder 11. When the movable column 8 drives the connecting rod 10 to move, the connecting rod 10 will move along the inside of the fixed cylinder 11. By providing the fixed cylinder 11, the fixed cylinder 11 will limit the movement of the connecting rod 10, thereby keeping the brush 12 in a stable state when it moves.

[0034] Furthermore, a second motor 23 is provided on one side of the base 1. One end of the second motor 23 is fixedly connected to a threaded rod 24. One end of the threaded rod 24 is threadedly connected to a threaded seat 25. The top of the threaded seat 25 is fixedly connected to a movable clamping plate 26. The top of the base 1 is fixedly connected to a fixed clamping plate 27. Two slots 28 are machined at both ends of the fixed clamping plate 27. The two ends of the movable clamping plate 26 are movably connected to the inside of the slots 28.

[0035] When it is necessary to clamp and fix the metal tube, the second motor 23 is started. The second motor 23 will drive the threaded rod 24 to rotate. The threaded rod 24 will drive the threaded seat 25 to move. The threaded seat 25 will drive the movable clamping plate 26 to move towards the fixed clamping plate 27, so that the two ends of the movable clamping plate 26 move into the groove 28. Thus, the metal tube can be clamped and fixed conveniently through the movable clamping plate 26 and the fixed clamping plate 27, which in turn facilitates the grinding of the inner wall of the metal tube.

[0036] Furthermore, the base 1 has a groove 29 machined inside, and the threaded seat 25 is movably connected inside the groove 29. When the threaded rod 24 rotates and drives the threaded seat 25 to move, the threaded seat 25 will move along the inside of the groove 29. The groove 29 will limit the movement of the threaded seat 25, so that the movable clamping plate 26 remains stable when it moves.

[0037] Furthermore, one end of the connecting column 13 is fixedly connected to two sliders 21, and the two inner cavities are machined with two sliding grooves 22. The sliders 21 are slidably connected inside the sliding grooves 22. When the hydraulic cylinder 20 drives the connecting column 13 to move, the connecting column 13 will drive the sliders 21 to move. The sliders 21 will move along the inside of the sliding grooves 22. By providing the sliding grooves 22, the sliding grooves 22 will limit the movement of the sliders 21, thereby limiting the movement of the connecting column 13.

[0038] Furthermore, a pull rod 30 is provided on the outer side of the handwheel 4. A limit rod 31 is fixedly connected to one side of the pull rod 30. One end of the limit rod 31 is plugged into the inside of the fixed plate 3. A plurality of limit holes 32 are machined on one side of the fixed plate 3. One end of the limit rod 31 is plugged into the inside of the limit hole 32.

[0039] When it is necessary to rotate the handwheel 4, first pull the lever 30. The lever 30 will drive the limit lever 31 to move, so that the limit lever 31 is disengaged from the inside of the limit hole 32, thereby allowing the handwheel 4 to be rotated. When the limit lever 31 is inserted into the inside of the limit hole 32, the handwheel 4 is limited by the limit lever 31 to prevent the position of the brush 12 from moving.

[0040] Furthermore, a return spring 33 is provided on the outside of the limiting rod 31. One end of the return spring 33 is fixedly connected to the outside of the handwheel 4, and the other end of the return spring 33 is fixedly connected to the inside of the pull rod 30. With the return spring 33 provided, when the pull rod 30 is pulled, the pull rod 30 will drive the return spring 33 to stretch. When the pull rod 30 is released, the return spring 33 will return to its original position and retract. The return spring 33 will drive the limiting rod 31 to move, so that the limiting rod 31 can be inserted into the inside of the limiting hole 32.

[0041] Furthermore, the sleeve 14 is externally fixedly connected to a limiting ring 15, and the column 2 is internally machined with a limiting groove 16. The limiting ring 15 is rotatably connected inside the limiting groove 16. By setting the limiting groove 16, the limiting groove 16 will limit the movement of the limiting ring 15, and the limiting ring 15 will limit the movement of the sleeve 14, thereby keeping the sleeve 14 in a stable state when rotating.

[0042] Working principle: By rotating the handwheel 4, the handwheel 4 will drive the rotating shaft 5, the first gear 6 and the second gear 7 to rotate. The second gear 7 will drive the movable column 8 to move. The movable column 8 will move along the inside of the movable groove 9. At the same time, the movable column 8 will drive the connecting rod 10 to move. The connecting rod 10 will drive the brush 12 to move, so that the brush 12 will come into contact with the inner wall of the metal tube. This allows for grinding and cleaning of metal tubes with different inner diameters. After the position of the brush 12 is adjusted, the first motor 17 is started. The first motor 17 will drive the third gear 18, the fourth gear 19, the sleeve 14 and the connecting column 13 to rotate. The connecting column 13 will drive multiple brushes 12 to rotate through the fixed plate 3. At the same time, the hydraulic cylinder 20 is started. The hydraulic cylinder 20 will drive the connecting column 13 to move. The connecting column 13 will drive the fixed plate 3 and the brushes 12 to move back and forth along the inside of the metal tube, thus facilitating the grinding and cleaning of the inner wall of the metal tube.
