[0042] 1. According to the different diameters of the lamp tubes to be polished, the initial positions of the first telescopic rod 16 and the second telescopic rod 17 are adjusted by the controller, and a certain telescopic threshold is set;

[0043] 2. Place the lamp tube to be polished between the upper and lower carriages 18 and wait for it to enter the polishing unit;

[0051] The correction steps of step 7 are as follows: when the ultrasonic sensor 29 detects that the lamp tube passes through the through hole 8, the controller controls the adjusting motor 12 to drive the adjusting roller 2 to rotate, and drives the lamp tube to move away from the ultrasonic sensor 29 through the anti-slip rib 30, until the ultrasonic sensors 29 outside the two fixing seats 3 cannot detect the position of the lamp tube;
