[0033] refer to Figure 4 The transmission structure 13 includes a bidirectional screw 14 movably connected to the inside of the connecting frame 11 through a bearing, and the machine base 8 is sleeved on the surface of the bidirectional screw 14 and threadedly connected to the bidirectional screw 14.

[0034] As a technical optimization solution of the present invention, the cooperation of the bidirectional screw 14 and the guide rod 15 realizes the relative movement of the machine base 8, so that the distance between the polishing wheel 6 and the pipe workpiece 3 can be easily adjusted, which not only improves the adjustment accuracy, but also makes the entire adjustment process more stable and reliable.

[0035] refer to Figure 4 Both sides of the interior of the connecting frame 11 are fixedly connected with guide rods 15 located on both sides of the bidirectional screw 14, and the machine base 8 is sleeved on the surface of the guide rods 15 and is slidably connected to the guide rods 15.

[0036] As a technical optimization solution of the present invention, by providing the guide rod 15, the movement trajectory of the machine base 8 can be limited, thereby preventing equipment damage or degradation of polishing effect due to improper movement.

[0037] refer to Figure 4 The side of the limiting plate 12 away from the connecting frame 11 is movably connected to a roller 16 through a pin, and the outer surface of the roller 16 contacts the surface of the shift fork 10.

[0038] As a technical optimization solution of the present invention, the roller 16 on the limit plate 12 is in contact with the surface of the fork 10, which reduces friction and wear and extends the service life of the equipment. At the same time, the design of the roller 16 also improves the stability of the fork 10 during movement, preventing the polishing effect from being reduced or equipment failure caused by vibration or impact.

[0039] refer to Figure 4 The surface of the shift fork 10 is inlaid with a ball 17 , and the side of the ball 17 away from the shift fork 10 contacts the surface of the polishing wheel 6 .

[0040] As a technical optimization solution of the present invention, by providing the ball 17, the friction and wear between the fork 10 and the polishing wheel 6 can be reduced, thereby improving the smoothness of the polishing process. At the same time, the rolling action of the ball 17 also helps to disperse the heat and stress during the polishing process, thereby protecting the surface of the polishing wheel 6 and the fork 10 and extending the service life of the equipment.

[0041] refer to Figure 4 The limit plate 12 is composed of two cross bars 18, which are arranged perpendicular to each other at right angles. A spring hinge 19 is fixedly connected between the two cross bars 18. When the limit plate 12 is out of contact with the fork 10, the cross bar 18 can be folded by the spring hinge 19.

[0042] As a technical optimization solution of the present invention, by setting a spring hinge 19 and a cross bar 18, when the limit plate 12 is out of contact with the fork 10, the cross bar 18 can be folded using the spring hinge 19, which not only saves space, but also enables the limit plate 12 to flexibly adapt to different working environments and workpiece sizes, thereby avoiding the limit plate 12 affecting the disassembly and assembly of the polishing wheel 6.

[0043] The working principle and use process of the present invention are as follows: before the equipment is started, the pipe workpiece 3 is placed on the top of the base 1 and is located on the inner side of the polishing assembly 2. At this time, the transmission motor 4, the connecting rod 5, the polishing wheel 6 and the supporting structure 7 are all in the initial position and are ready to enter the working state. After the transmission motor 4 is started, its output end drives the connecting rod 5 to rotate, and then drives the polishing wheel 6 to rotate. The inner side of the polishing wheel 6 maintains a certain contact with the surface of the pipe workpiece 3, and is ready for polishing operation. At the same time, the machine base 8 in the supporting structure 7 is arranged relative to the polishing assembly 2 through the transmission structure 13. The top of the machine base 8 is fixed on the transmission motor 4, and one side of the machine base 8 is connected by the connecting block. 9 and the shift fork 10 are connected to the polishing wheel 6. The shift fork 10 is sleeved on the connecting rod 5 and uses the ball 17 to squeeze and limit the polishing wheel 6. When the outer diameter of the polishing wheel 6 is reduced due to wear, the user can rotate the bidirectional screw 14 so that the bidirectional screw 14 uses the machine base 8 to carry the support structure 7 together with the transmission motor 4 to move synchronously. When the shift fork 10 moves to the inner side of the limit plate 12 and disengages from the limit plate 12, the shift fork 10 can swing with the pin shaft inside the connecting block 9 as the axis and disengage from the polishing wheel 6. Then the user can replace the polishing wheel 6 and push the shift fork 10 to reset after the replacement and use the limit plate 12 to fix the shift fork 10 again.

[0044] To sum up: the polishing equipment for metal pipes provides stable support for the polishing wheel 6 through the combination of the machine base 8, the connecting block 9 and the fork 10, and the design of the fork 10 allows it to be adjusted as the relative position of the polishing wheel 6 and the pipe workpiece 3 changes, ensuring stability and adaptability during the polishing process. At the same time, when the fork 10 is out of contact with the limit plate 12, it can facilitate the user to quickly replace the polishing wheel 6, thereby improving the versatility and flexibility of the equipment.
