Summary of the invention
For the problems referred to above, the utility model provides a kind of little feeding finishing structure, and it is in the situation that use common servomotor, can be so that the feed accuracy of dresser be high, thus so that the low cost of manufacture of dresser.
A kind of little feeding finishing structure, its technical scheme is such: it comprises casing, servomotor, diamond pen, slide, the diamond pen driving shaft, described servomotor drives described slide by ball screw, described slide clamps the line slideway in the described casing, described diamond pen is fastenedly connected described diamond pen driving shaft, it is characterized in that: be provided with the spline that drives rectilinear direction along described diamond pen in the described casing, the outer edge surface of described diamond pen driving shaft is opened and is specially spline housing, the spline housing cooperation of described diamond pen driving shaft is loaded in the described spline, the lower end of described slide is provided with outer male member away from a side of described diamond pen, described outer male member press-fits the upper end in lever, the middle downside of described lever by shaft support in described box house, the lower end of described lever is loaded on briquetting towards projection one side pressure of described diamond pen, and described briquetting is fastenedly connected the tail end of described diamond pen driving shaft.
It is further characterized in that: described outer male member is specially hard alloy blocks, steel ball, and away from a side of described diamond pen, the position corresponding to described hard alloy blocks of described lever is provided with described steel ball to described hard alloy blocks evagination in the lower end of described slide;
The lower end of described lever is specially bottom hard alloy blocks, bottom steel ball towards described diamond pen projection one end, described bottom steel ball is installed in the central recess of described briquetting, described bottom hard alloy blocks is close to described bottom steel ball, is provided with disk spring between the tail end of described briquetting and described diamond pen driving shaft;
The two ends of described rotating shaft are supported on the both sides, inside of described casing by bearing.
After adopting said structure of the present utility model, the driven by servomotor slide moves backward, the outer male member of slide lower end is pressed on lever, so that the lower briquetting that is pressed on of lever, briquetting travels forward, so that the spline housing of diamond pen driving shaft travels forward along spline, and then so that diamond pen is finished feeding, wherein since the middle downside of described lever by shaft support in described box house, be that lever is to have big lever than (definite value), location positioning by rotating shaft, thereby the ratio of the amount of feeding of the servomotor amount of feeding and diamond pen is the big lever ratio of lever, it is in the situation that use common servomotor, can be so that the feed accuracy of dresser be high, thus so that the low cost of manufacture of dresser.
