[0002] The equipment for polishing the inner wall of stainless steel pipe mainly includes mechanical polishing and electrolytic polishing. Mechanical polishing uses sandpaper to move back and forth inside the stainless steel pipe to polish the inner wall. Electrolytic polishing equipment is more complex and expensive than mechanical polishing equipment, but its polishing quality is better than mechanical polishing and has a wider adaptability.

[0003] In the electrolytic polishing process of the inner wall of a stainless steel pipe, an electrolyte needs to be passed into the pipe body, and a direct current is passed through the pipe body and the electrolyte in the pipe body to complete the electrolytic polishing process. During the current polishing work, the stainless steel pipe is directly placed in the electrolytic cell and the electrolyte is passed for polishing. However, during the polishing, the rust produced by the polishing is easily blocked inside the stainless steel pipe, which requires subsequent cleaning. In addition, it is difficult to put stainless steel pipes of different lengths into the electrolytic cell for polishing. Utility Model Content

[0006] The support adjustment mechanism comprises a support frame, an adjustment slot for height adjustment is provided inside the support frame, an adjustment column is clamped inside the adjustment slot, and a nut for fixing and limiting is screwed on the surface of the adjustment column.

[0007] As an improvement of the above technical solution, a diversion mechanism is installed between the support and adjustment mechanisms, and the diversion mechanism includes a diversion box, a diversion pipe is arranged on one side of the diversion box, a valve is installed inside the diversion pipe, and a plug connector is arranged at one end of the diversion pipe.

[0008] As an improvement of the above technical solution, the shunt tubes are provided in multiple groups and are installed equidistantly on one side of the shunt box. An electrode rod is also provided inside the plug connector, and the plug connector adopts a separate conical structure plug connector.

[0009] As an improvement of the above technical solution, a conveying mechanism is also arranged on the other side of the diversion mechanism, and the conveying mechanism includes a conveying pump, and an isolation net is also arranged on the surface of the conveying pump.

[0011] Beneficial effects of the utility model:

[0012] By adjusting the adjusting column inside the adjusting groove, the height and angle of the diversion mechanism on which the stainless steel pipe is installed can be adjusted, so that the stainless steel pipe can be inserted into the electrolytic cell for circuit connection when electrolytic polishing of stainless steel pipes of different lengths is performed, and the adjusting column can be fixed after height adjustment and angle adjustment by means of a nut threaded on the outside of the support frame, so as to avoid falling during the electrolysis operation and improve stability during operation.
