Polishing device

The utility model discloses a polishing device, which relates to the technical field of umbrella rib pipe processing and comprises a processing table, a first fixing seat, a second fixing seat and a polishing mechanism, and the second fixing seat is positioned at one end of the first fixing seat. By arranging the polishing mechanism, the output end of a first motor rotates to drive an upper limiting block to move downwards through mechanical transmission, an umbrella rib pipe is clamped and limited in a first semi-arc-shaped groove and a second semi-arc-shaped groove, and the output end of a second motor rotates to drive a polishing assembly to move through mechanical transmission; the polishing assembly reciprocates on the outer wall of the rotating rod, through the structure, clamping and limiting operation on the umbrella rib pipe to be polished is facilitated, compared with traditional manual clamping and limiting operation on the umbrella rib pipe by workers, the overall safety of the device is improved,
