Summary of the invention
Technical problem to be solved in the utility model is at above-mentioned deficiency, can conveniently install and fix the accurately simple bearing eccentric adjusting fixed mechanism of eccentric adjusting and provide a kind of.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of bearing eccentric adjusting fixed mechanism, comprise the bearing that is engaged on the guide rail, bearing element cooperates the drive handpiece body, guide rail is fitted on the foundation mass, the technical measures of taking comprise: bearing cone is connected with the bearing eccentric shaft, this bearing eccentric shaft has the extension, and its periphery is with packing ring in proper order, and cam jacket and back-up ring reset; This bearing eccentric shaft also has inner chamber, and this inner chamber is provided with the nail through the securing member apical grafting, and the chamber face of this inner chamber and nail outer peripheral face have that tensioner is fitted and the tensioner binding face that constitutes; And bearing eccentric shaft extension has open-ended, forms free space between this bearing eccentric shaft end opening and the triangle support plate.
The technical measures of taking also comprise: the nail head has the applying inclined-plane, and the internal chamber wall that is positioned at the bearing eccentric shaft end is shaped on the boss inclined-plane, and nail applying inclined-plane and bearing eccentric shaft boss inclined-plane constitute the tensioner binding face.
Securing member is to have the soket head cap screw that unscrews or screw the effect of apical grafting nail, nail is through this soket head cap screw apical grafting, nail applying inclined-plane and the extruding of bearing eccentric shaft boss inclined-plane are fitted, and it is big that the external diameter of bearing eccentric shaft extension becomes, and tensioner is fixed on the cam jacket that resets.
Soket head cap screw unscrews the adjusting of apical grafting nail, and the bearing eccentric shaft is matched in clearance with the cam jacket that resets, through regulating the operating angle of bearing eccentric shaft, control bearing off-centre to the applying guide pass after, screw soket head cap screw and fix.
Compared with prior art, the bearing cone that the utility model adopts is connected with the bearing eccentric shaft, and this bearing eccentric shaft has the extension, and its periphery is with packing ring in proper order, and cam jacket and back-up ring reset; This bearing eccentric shaft also has inner chamber, and this inner chamber is provided with the nail through the securing member apical grafting, and the chamber face of this inner chamber and nail outer peripheral face have that tensioner is fitted and the tensioner binding face that constitutes; And bearing eccentric shaft extension has open-ended, forms free space between this bearing eccentric shaft end opening and the triangle support plate.Nail is through the securing member apical grafting, and nail applying inclined-plane and the extruding of bearing eccentric shaft boss inclined-plane are fitted, and it is big that the external diameter of bearing eccentric shaft extension becomes, and tensioner is fixed on the cam jacket that resets.And by unscrewing the adjusting of apical grafting nail, the bearing eccentric shaft is matched in clearance with the cam jacket that resets, and through regulating the operating angle of bearing eccentric shaft, control bearing off-centre is to the applying guide pass.Its axial physical dimension reduces greatly, can conveniently install and fix simultaneously, and eccentric adjusting is accurately simple.
