Detailed Description

As shown in fig. 1-3:

the bidirectional screw 23 can drive the symmetrically installed sliding blocks III 34 to be close to or far away from each other, the round pipe clamp 29 moves along with the sliding blocks III 34 to clamp the two ends of a round pipe to be polished, and the positioning bolt II 24 is screwed down to enable the positioning bolt 24 to be in close contact with the bidirectional screw 23, so that the bidirectional screw 23 can be locked.

The round tube to be polished can be adjusted to a proper polishing position by adjusting the upper and lower positions of the telescopic blocks 20, and the telescopic blocks 20 can be locked by tightening the first positioning bolt 19 to be in close contact with the telescopic blocks 20.

The position of the telescopic circular tube 25 in the telescopic circular groove 22 is adjusted, so that the front and back positions of the rotary disc 8 can be adjusted, the rotary disc is suitable for circular tubes to be polished with different lengths, and the positioning bolt III 28 is screwed down to be in close contact with the telescopic circular tube 25, so that the telescopic circular tube 25 can be locked.

The second driving motor 21 drives the telescopic circular groove 22 to rotate, the rotary disc 8 and the telescopic circular tube 25 are driven to rotate due to the fact that the telescopic circular tube 25 is locked by the third positioning bolt 28, and the circular tube clamp 29 is driven to rotate by the rotary disc due to the fact that the bidirectional screw 23 is locked by the second positioning bolt 24, and finally the circular tube to be polished is driven to rotate at a high speed.

The driving motor I7 drives the driving wheel I3 to rotate through the driving wheel II 6 and the driving belt 4, the driving wheel I3 drives the belt roller 2 to rotate through the rotating shaft 11, and the belt roller 2 drives the polishing abrasive belt 15 to rotate at a high speed, so that the round pipe to be polished is polished.

The positions of the sliding blocks 12 at the two ends of the belt roller 2 can be adjusted by adjusting the positions of the adjusting bolts 14 at the two ends of the belt roller 2, so that the positions of the belt tube wheels 2 are adjusted, and the aim of tensioning and polishing the abrasive belt 15 is fulfilled.

The specific working process comprises the following steps: two ends of the circular tube can be respectively placed in front and back opposite 29 through the adjustment 25, the two 29 clamp the end part of the circular tube, the telescopic block 20 is adjusted, the circular tube is contacted with the polishing abrasive belt 15, the driving motor two 21 and the driving motor one 7 are started, and thus the outer wall of the circular tube can be polished by the polishing abrasive belt 15; if the length of the round tube is greater than the length or width of the sanding belt 15, the expansion slot 27 can be pushed back and forth to move the round tube over the sanding belt 15, which will sand the outer wall of the whole round tube.

If the length of the tube is long, for example, the length of the tube is equal to or greater than the length of the sanding belt 15, both ends of the tube are fixed in the clamps 29 at the rotating shaft 11, and the tube is sanded by using the tube clamps 29 at the rotating shaft 11 as clamps.

If the length of the round tube is shorter, for example, the length of the round tube is greater than or equal to the width of the sanding belt 15, two ends of the round tube and 29 on two sides of the sanding belt 15 can be used as clamps to clamp two ends of the round tube, and the round tube is attached to the surface of the sanding belt 15, so that the round tube can be sanded, when the length of the round tube is greater than the width of the sanding belt 15, the telescopic grooves 27 on two sides of the sanding belt 15 are pushed back and forth, and the outer wall of the round tube is fully contacted with the sanding belt 15 for sanding.

The contact surface between the polishing abrasive belt 15 and the round pipe is large, and the rotary polishing abrasive belt 15 and the rotary round pipe are matched for polishing, so that the polishing speed is improved.
