Technical Field

[0001] This utility model relates to the field of polishing technology, specifically to a pipe polishing device. Background Technology

[0002] Polishing is a processing method that uses mechanical, chemical, or electrochemical actions to reduce the surface roughness of a workpiece in order to obtain a bright and smooth surface. It is a finishing process that uses polishing tools and abrasive particles or other polishing media to modify the surface of a workpiece. Polishing does not improve the dimensional accuracy or geometric accuracy of the workpiece, but aims to obtain a smooth surface or mirror gloss. Sometimes it is also used to eliminate gloss.

[0003] In the existing technology, pipes often need to be polished during the production process. However, most existing polishing equipment can only polish the outside or inside of the pipe separately. As a result, the pipe needs to go through two polishing processes, which will affect the polishing efficiency when the pipe needs to be polished in batches. Utility Model Content

At this time, the rotation of the first lead screw 12 drives the mounting base 4, the threaded pipe 6 and multiple polishing heads 27 to move. Then, the multiple polishing heads 27 polish the pipe from the inside, and the polishing plate 19 polishes the pipe from the outside. This achieves the effect of polishing the inner and outer walls of the pipe at the same time.

[0025] Based on the above embodiments, refer to Figure 2 , Figure 3 , Figure 4 and Figure 6The adjusting assembly includes: a second lead screw 14, which is threadedly connected to the inside of a threaded tube 6. One end of the second lead screw 14 is rotatably connected to an adjusting head 24.

[0027] Working principle: Please refer to Figures 1-6 As shown, during use, the operator clamps the pipe to be polished using the electric chuck 3, and then rotates the second lead screw 14. Under the threaded transmission of the second lead screw 14 and the threaded pipe 6, the second lead screw 14 will drive the adjusting head 24 to move. At this time, the inclined surface on the side of the adjusting head 24 will squeeze the multiple connecting brackets 25, and the multiple connecting brackets 25 will rotate and pull the rubber fastening ring 23 to extend. In this way, the spacing between the multiple polishing heads 27 can be adjusted to adapt to pipes with different inner diameters.

[0028] After the above steps are completed, the operator rotates the first lead screw 12. Under the threaded transmission of the first lead screw 12 and the mounting base 4, the mounting base 4 will drive the threaded tube 6 on its side and multiple polishing heads 27 to move, and the multiple polishing heads 27 will enter the inside of the pipe. At this time, the operator drives the pipe to rotate by rotating the electric chuck 3, and continues to rotate the first lead screw 12 to move the multiple polishing heads 27. The multiple polishing heads 27 will polish the pipe from the inside. At the same time, under the action of the rebound force of multiple springs 16, the polishing plate 19 will always be in contact with the outside of the pipe and polish its outer wall when the pipe rotates. This achieves the effect of polishing the inner and outer walls of the pipe at the same time.
