Abstract
A kind of high-precision vertical revolving worktable, it includes a vertical revolving worktable, on the power shaft below workbench pinion is being installed on the pedestal of vertical revolving worktable, be engaged with a gear ring that is fixed on the workbench on the pinion, concentric is fixed with a bearing base in the gear ring, in the centre bore of bearing base shaft-cup is installed, one bearing with cross roller bearing is installed on the bearing base outer wall between pedestal and the gear ring, be fixed with the inner ring gland on the pedestal of bearing with cross roller bearing top, the outside of radial bearing is fixed with seat in the bearing on gear ring, on pedestal, be fixed with bearing base corresponding to seat in the bearing, in bearing, be separately installed with roller between seat and between following and in the bearing and the radial bearing, the roller outside is fixed with a circle bearing block pressing plate below gear ring, by bearing base a gear clearance is installed with the corresponding opposite side of power shaft and adjusts piece on pedestal.Be specially adapted to use on the lathe, grinding machine of high accuracy slewing.
Description
Technical field:
The present invention relates to lathe, the high-precision vertical revolving worktable of installing on particularly a kind of lathe that is applicable to the high accuracy slewing, the grinding machine.
Background technology:
Existing high-precision vertical revolving worktable, its precision adjustment is respectively the axial and radial accuracy that adopts plane thrust bearing and circular cone ball bearing control turntable, because what adopt is the precision of controlling separately separately, be difficult to keep and coordinate the synthesis precision of turntable, and adjustment is to rely on its butterfly spring that bearing inner race is compressed, it can only adjust the variation of pressure size, and all can't realize the pressure adjustment on specific direction, the orientation.
Summary of the invention:
The purpose of this invention is to provide a kind of can Comprehensive Control axially and the high-precision vertical revolving worktable of radial accuracy.
Technical scheme of the present invention is finished as follows, it includes a vertical revolving worktable, it is characterized in that: on the power shaft below workbench pinion is being installed on the pedestal of vertical revolving worktable, be engaged with a gear ring that is fixed on the workbench on the pinion, concentric is fixed with a bearing base in the gear ring, in the centre bore of bearing base shaft-cup is installed, one bearing with cross roller bearing is installed on the bearing base outer wall between pedestal and the gear ring, be fixed with the inner ring gland on the pedestal of bearing with cross roller bearing top, the outside of radial bearing is fixed with seat in the bearing on gear ring, on pedestal, be fixed with bearing base corresponding to seat in the bearing, in bearing, be separately installed with roller between seat and between following and in the bearing and the radial bearing, the roller outside is fixed with a circle bearing block pressing plate below gear ring, by bearing base a gear clearance is installed with the corresponding opposite side of power shaft and adjusts piece on pedestal.It adjusts the end-play of bearing by the bearing inner race gland, evenly press down and the radially negative play of the automatic control of reaction force with the screw of adjusting on the piece, the sideshake of gear can be realized by adjusting piece, adjust the combination precision that the inner ring gland guarantees high-precision centripetal thrust force and conical bearing.
Description of drawings:
Accompanying drawing is a structural representation of the present invention.
The specific embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing, the present invention is improvements over the prior art, it is that a pinion 14 is installed on the power shaft 15 below workbench 1 on the pedestal 13 of existing vertical revolving worktable, be engaged with a gear ring 2 that is fixed on below the workbench on the pinion, concentric is fixed with a bearing base 5 in the gear ring, shaft-cup 6 is installed in the centre bore of bearing base, one bearing with cross roller bearing 7 is installed on the base outer wall between bearing base and the gear ring, be fixed with inner ring gland 4 on the pedestal of bearing with cross roller bearing top, the outside of radial bearing is fixed with seat 10 in the bearing on gear ring, on pedestal, be fixed with bearing base 11 corresponding to seat in the bearing, in bearing, be separately installed with roller 8 between seat and between following and in the bearing and the radial bearing, 9, the roller outside is fixed with a circle bearing block pressing plate 3 below gear ring, on pedestal, by bearing base a gear clearance is installed and adjusts piece 12, on the adjustment piece, adjustment screw is installed with the corresponding opposite side of power shaft.The present invention is owing to be equipped with a bearing base that precision is high, radial and axial the beating that guarantees its gear ring all can be controlled effectively, and adjust bearing end-play by bearing inner race gland 4, rely on screw evenly to press down and control radially negative play automatically with the reaction of jackscrew, pinion directly is contained in and drives gear ring and workbench rotation on the power shaft, and the sideshake of gear is to realize by adjusting piece.Can guarantee the combination precision of high-precision bearing with cross roller and taper roll bearing by adjusting the inner ring gland, thereby reach precision≤10 micron of vertical working platform.
