Grinding head mechanism for polishing

According to the technical scheme, the grinding head mechanism for polishing machining comprises a grinding head body, a connecting transverse rod is arranged at one end of the grinding head body, a limiting connecting mechanism is arranged between the connecting transverse rod and the grinding head body, and the limiting connecting mechanism comprises a limiting annular plate and a movable arc plate. The limiting ring plate is located at the end, close to the grinding head body, of the connecting cross rod and fixedly connected with the grinding head body, the two movable arc plates are located on the two sides of the end, close to the grinding head body, of the connecting cross rod correspondingly and fixedly connected with the connecting cross rod, and the two ends of one side in the limiting ring plate are fixedly connected with fixed arc rods correspondingly; the grinding head mechanism for polishing machining has the beneficial effects that the practicability of the grinding head mechanism is improved,
