Description

Technical Field

It is difficult to polish both sides of the tubular injection molded parts at the same time, resulting in low processing efficiency.

[0004] Therefore, it is of great significance to provide a device for simultaneous polishing of the inner and outer walls of injection-molded pipe parts to solve the problems existing in the prior art. Utility Model Content

[0008] Preferably, the outer diameter of the main polishing roller is adjustable to accommodate pipes with different inner diameters; the auxiliary polishing roller and the rotating shaft are installed with a clearance fit to ensure uniform pressure on the outer wall of the pipe during the polishing process.

[0009] Furthermore, the working surface of the clamping block of the pneumatic clamp is provided with anti-slip texture and covered with flexible material to avoid damaging the surface of the pipe during clamping.

[0010] Compared with the prior art, the beneficial effects of this utility model are: Simultaneous polishing of inner and outer walls: The main polishing roller is driven by the spindle to polish the inner wall, while the auxiliary polishing roller polishes the outer wall at the same time, which significantly improves the processing efficiency.
