The invention discloses an annular glass column circular head grinding device. The device comprises a frame, and is characterized in that an annular bracket is arranged on the frame; the annular bracket includes corresponding long bases and corresponding short bases; the long bases are correspondingly provided with multiple fixed modules with equal distances; a grinding module is correspondingly arranged on one side of each fixed module; a driving module for driving the annular bracket to perform a reciprocating motion is arranged on one side of one short base; the fixed modules include fixed plates; the fixed plates are arranged on the annular bracket; vertical plates are vertically arranged at two ends of the fixed plates, and are correspondingly provided with through holes; roller shafts are connected between the through holes, and are coated with tripods capable of rotating along with the roller shafts; fixed blocks are connected to the front ends of the tripods; vertical rods are vertically arranged on the fixed blocks, and are coated with multiple bearing blocks at the upper parts of the fixed blocks; and butting columns are arranged at the lower parts of the vertical rods. The annular glass column circular head grinding device has such advantages as simple structure, convenience for use and low cost.
