The invention relates to a honing head opening mechanism. A piston is arranged and fixed on a driving shaft through a middle hole thereof and a bearing; a flange sleeve is arranged and fixed on each of the two end hole opening of the piston; two ends of the driving shaft penetrate out from the middle holes of the flange sleeves; the outer cylindrical surface of the piston is provided with a cylinder; the flange sleeves penetrates through the middle hole of a cylinder cover on the ends of the flange sleeves; the cylinder cover on the lower part of the cylinder is provided with a bearing pedestal; a bearing is arranged and fixed on the middle hole opening of the bearing pedestal; a push rod is arranged in one end hole of the driving shaft; two pin shafts are fixed together with the push rod through elongated slots on two sides of the driving shaft; and an inner ring of the bearing, which is arranged in the inner hole of the bearing pedestal, is clamped between the two pin shafts. The honing head opening mechanism can work reliably, the sealing component has a long service life, and the hydraulic cylinder can not leak oil easily.
Description
technical field [0001] The invention relates to a honing machine, in particular to a honing head expanding and opening mechanism of the honing machine, and belongs to the technical field of honing machines. Background technique [0002] There are two types of opening methods for the grinding bars on the honing head: mechanical (generally using a spring) and hydraulic (using a piston rod of a hydraulic cylinder). The mechanically opened grinding rod type grinding head, when the grinding rod is normally worn, the tension nut must be manually adjusted frequently to compensate for the positive pressure on the inner hole of the workpiece that is reduced due to the grinding rod wear, so the work efficiency is low. At present, the hydraulic opening grinding head used by most manufacturers can achieve uniform opening and good effect, but most of the hydraulic push rods are pistons that rotate with the grinding head rod, and the O-rings on the inner wall of the cylinder and the pisto...
