Abstract
The invention discloses an eccentric mechanism used on a working table of a vertical grinder, which comprises a working table, wherein a rotating shaft is installed on the working table, a bearing is assembled on the rotating shaft, an eccentric rotary table is installed on the working table and matched with a bearing outer ring, a worm gear is installed in the eccentric rotary table, a worm is assembled on the working table and meshed with the worm gear, and a disc spring is installed in a circular arc shaped groove of the eccentric rotary table; and the disc spring and the eccentric rotary table are connected together with the working table through screws. As the worm gear and worm drive mode is adopted, the accurate control of eccentricity is easy to realize; the rotating shaft is supported through a preloaded bearing during the assembly, and not only the high rotation accuracy of the eccentric rotary table is ensured, but also zero clearance in the rotating shaft of the eccentric rotary table is ensured, so that the stability and the accuracy in eccentric adjustment are ensured; and as the eccentric rotary table is fixed on the working table through the preloaded bearing and the disc spring, the eccentricity during the machining process is more convenient to adjust.
Description
Technical field:
The present invention relates to a kind of eccentric stiffener, be specially adapted to use on the numerical control vertical grinder.
Background technology:
Eccentric bushing is mechanically used comparatively general at capacity eccentric bearing, reductor etc., in order to improve mechanical precision, eccentric bushing is many employing grindings in recent years.At present the grinding eccentric bushing has dual mode: eccentric frock, workbench link with feed shaft, adopt eccentric frock, can't clamped one time finish the processing of two off-centre operations, and efficient is low, and precision is general.Another kind of workbench adopts direct driving motor, with one of them circle of feed shaft interlock processing.This kind method requires machine tool numerical control system to have linkage function, and the dynamic response performance of lathe integral body is had relatively high expectations, and cost is also higher.Therefore, need to seek a kind of lower cost processing method for the higher eccentric bushing of required precision, also will guarantee simultaneously the machining accuracy of eccentric bushing.
Summary of the invention:
Task of the present invention is to propose the vertical grinding eccentric bushing of a kind of usefulness, is easy to realize the accurate control of offset, makes the eccentric stiffener on the vertical grinder workbench that the adjustment offset becomes more convenient in the process.Task of the present invention is finished like this, eccentric stiffener on the vertical grinder workbench, it comprises workbench, it is characterized in that: rotating shaft is housed on the workbench, bearing assemble is in rotating shaft, and eccentric turntable is contained on the workbench and cooperates with described bearing outer ring, and described eccentric turntable is equipped with worm gear inside, worm screw is assemblied on the workbench and meshes with described worm gear, and the dish spring is contained in eccentric turntable circular arc along in the groove.Described dish spring and described eccentric turntable link together by screw and workbench.Described rotating shaft is to depart from the position at workbench center to install, and rotates by worm screw and drives eccentric turntable according to doing oscillating motion centered by the rotating shaft.
The present invention has following effect: the present invention adopts Worm Wheel System, and gearratio is larger, is easy to realize the accurate control of offset.The rotating shaft assembling adopts preloaded bearing to support, and has both guaranteed the high accuracy of the rotation of eccentric turntable, guarantees again eccentric turntable rotating shaft part gapless, thereby guarantees eccentric stability and the accuracy of adjusting.Eccentric turntable adopts preloaded bearing and dish spring mode to be fixed on the workbench, makes to adjust offset in the process and become more convenient.
