The Zero calibration apparatus of adjustable honing head of the present invention, comprise that zero-base Zuo He center, school offers the school nullring in zero hole, school, also comprise guiding block, lower guiding block and center offer the guider ring of the first clear opening, zero-base Zuo center, described school offers up big and down small first step through hole, the center of described upper guiding block offers up-small and down-big second step through hole, the center of described lower guiding block offers the second clear opening, the small aperture of described second step through hole is more than or equal to the internal diameter of guider ring, the internal diameter of described guider ring equals the internal diameter of school nullring, the aperture of described the second clear opening is more than or equal to the internal diameter of school nullring, but be less than the external diameter of school nullring, described guider ring is arranged in the macropore of first step through hole and school zero-base seat matched in clearance, the part of guider ring protrusion zero-base seat upper surface, school is positioned at macropore and the upper guiding block matched in clearance of second step through hole, upper guiding block is bolted the upper end at school zero-base seat, described school nullring is arranged in the aperture of first step through hole and school zero-base seat matched in clearance, the lower surface of school nullring flushes with the lower surface of school zero-base seat, lower guiding block is bolted the lower end at school zero-base seat, and second step through hole, first step through hole, the first clear opening, the axial line of zero hole, school and the second clear opening overlaps.
The upper end of described second step through hole is provided with chamfering, and the lower end of described the second clear opening is provided with chamfering.
The present invention has following effect:
In the research and development advanced development of engine cylinder-body, according to aperture, different cylinders hole (being equivalent to the different size for adjustable honing head), when in the school zero, do not need to change school zero-base seat, only need to change different upper guiding block, lower guiding block, guider ring and the school nullrings (changing their aperture) of size, can realize rapidly the part replacement of Zero calibration apparatus, the parts of the Zero calibration apparatus to wearing and tearing or damage also can be realized replacing fast, shorten research and development trial-produce period, improved the service efficiency of parts; Do not need to make the integrative honing head Zero calibration apparatus of a whole set of different size specification specially, reduced manufacturing cost (because school zero-base seat is larger, manufacturing cost is very high).
