The invention relates to a cylinder hole
honing tool comprising a head body, an
abrasive strip base and a support body which are connected in sequence; an expansion cone is arranged in the head body and the
abrasive strip base, and
abrasive strips are arranged on the abrasive strip base; a cutter expansion rod is arranged in the head body, and the lower end of the cutter expansion rod is connectedwith the expansion cone; an upper cutter retracting spring and a lower cutter retracting spring are arranged at the upper and lower ends of the abrasive strip base, so that the abrasive strip base isattached to the expansion cone; a guide
alloy strip is arranged on the surface of the abrasive strip base, and chamfers are arranged at the upper and lower ends of the guide
alloy strip and the abrasive strips; and anti-collision rings which can be used for blocking and protecting the bottom ends of the guide
alloy strip and the abrasive strips are mounted on the support body. According to the cylinder hole
honing tool, the problem that the
honing abrasive strip, the honing head and the top of the cylinder hole are damaged due to swing of the honing tool is solved properly, and the equipmentstarting rate is increased; the product
machining quality is guaranteed, and the tool cost and work waste are reduced; and meanwhile, damage to the honing tool and the abrasive strips is avoided.
