Inner hole honing head with following supporting strips

An inner hole honing head with following supporting strips is mainly composed of the following components: an outer sleeve, a cylinder, internal and external taper sleeves, a sand strip rack, a sand strip, a supporting frame and supporting strips. A guide bar of the supporting frame abuts against an outer taper sleeve. A guide bar of the sand strip rack abuts against an inner taper sleeve. A double-ejector-rod cylinder is combined with a piston cylinder for pushing an inner taper sleeve and an outer taper sleeve to move, so the supporting frame telescopes along with the sand strip rack. Therefore in a honing process, the supporting strips can form following supports and always cling on an inner wall of a workpiece hole for keeping superposition between a rotation center line of the honing head and a center line of the workpiece hole always. In large-diameter inner-hole horizontal honing with a stationary workpiece, the honing head can cause consistent grinding amount of an upper part and a lower part of the i
