The invention provides an inner hole honing device for a quartz glass pipe. The device comprises a honing head (1) used for machining the inner hole of the quartz glass pipe, wherein the honing head (1) is located on one side of a fixing ring (32); the honing head (1) is provided with a grinding wheel part (11) and a honing rod (12); the grinding wheel part (11) comprises a coarse grinding wheel (13), a middle grinding wheel (15) and a fine grinding wheel (17); each of the three grinding wheels is provided with a cylinder outer surface; a spiral chip removal groove (18) is formed in the outersurface of each of the three grinding wheels; the chip removal grooves of the coarse grinding wheel, the middle grinding wheel and the fine grinding wheel are sequentially connected; a first joint isarranged between the coarse grinding wheel and the middle grinding wheel; the first joint is parallel to the axis of the honing rod; a second joint is arranged between the middle grinding wheel and the fine grinding wheel; the second joint is parallel to the axis of the honing rod; when the honing head is used for machining the quartz glass pipe, vibration of the quartz glass pipe generated is weakened and absorbed by a vibration damping cylinder (2) through the fixing ring (32).
