The honing head roundness structure according to claim 1, characterized in that, The method for the honing head circularity structure grinding tooling is characterized by including the following steps: S1. During use, first install the honing head (202) and the circularity body (201) between the first center pin (108) and the second center pin (109). Specifically, first connect and position the honing head (202) with the cylindrical hole and end face at the lower part of the circularity body (201) and transmit power through a transmission pin. Then, the end of the honing head (202) far from the circularity body (201) abuts against the side wall of the second center pin (109), and the first center pin (108) abuts against the other end of the circularity body (201). Then, move the moving block (205) outside the adjusting cross bar (204) and make the two arc-shaped rods (206) correspond to the upper and lower sides of the circularity body (201), and then fix them with the fastening screw rod and the convex block (203). S2. Loosen the locking screw (212), rotate the adjusting rod (207) clockwise, the adjusting rod (207) moves upward, and due to the limitation of the guiding rod (213), the adjusting sleeve (209) moves downward along the axis, pushing the rough honing ejector rod (210) inside the honing head (202). After the rough honing strips are ejected, the locking screw (212) is pushed onto the adjusting rod (207) to lock it; conversely, rotate the adjusting rod (207) counterclockwise, it will move downward, pushing the fine honing ejector rod (211) inside the honing head (202), the adjusting sleeve (209) retracts upward. After the fine honing strips extend, the locking screw (212) is pushed onto the adjusting rod (207) to lock it, and the circularity of the fine honing strips is carried out. S3. After the circular gauge tooling is adjusted, adjust the position of the grinding roller (305) and bring it into contact with the outer sidewalls of the rough and fine abrasive strips of the honing head (202) respectively. Then start the second motor (304), and the rough and fine abrasive strips of the honing head (202) can be ground.
