The utility model relates to cylindrical grinder, and specifically a kind of circular cone rod member drives positioning tool and cylindrical grinder.
Background technology
The circumference of cylindrical grinder (M13320 cylindricalo grinding lathe) drives rod member (can be referred to as driving lever or shift fork again, it is installed on the headstock rotating disc (driving wheel)) be generally cylinder, be cylindrical bar, (chuck one end was clamped on the workpiece by chuck when cylindrical bar rotated with main spindle box (headstock), the other end vertically arranges, and drives with circumference that rod member is perpendicular to be amplexiformed) drive the workpiece running; But in its operation process, because the workpiece that the machine tool hydraulic shakiness causes can not overlap fully with top, chuck can have small slip to the direction away from cylindrical bar on cylindrical bar, cause workpiece and emery wheel out of plumb, affects the cylindricity of workpiece processing.
The utility model content
The utility model provides a kind of circular cone rod member to drive positioning tool and cylindrical grinder.
Problem to be solved in the utility model is achieved in that
A kind of circular cone rod member drives positioning tool, it is a rod shaped structure, the one end is the circular cone shape body of rod, the other end is a cylindric body of rod, one end of the cylindric body of rod is fixed on the upper bottom surface (the upper bottom surface diameter of the circular cone shape body of rod is less than the bottom surface diameter) of the circular cone shape body of rod, and namely the upper bottom surface at the frustum of a cone is connected with a column body of rod.
The coning angle of the frustum of a cone is 15 ° ± 30 '.
A kind of cylindrical grinder, comprise the headstock that is provided with driving wheel, driven pulley tailstock case and driving lever and the chuck that are oppositely arranged, be relatively set with toply on the adjacently situated surfaces of headstock and tailstock case, two ends top and workpiece to be ground connect, and workpiece to be ground is by top location.Driving lever is a rod shaped structure, and the one end is circular cone shape, the coning angle of the frustum of a cone is 15 ° ± 30 ', an end is cylindric, an end of the cylindric body of rod is fixed on the upper bottom surface of the circular cone shape body of rod.Chuck one end is clipped on the workpiece to be ground, the circular cone shape body of rod phase cut-grafting of the other end and driving lever, and namely driving lever forms a conical drive rod; The column connecting-rod head of driving lever is fixed on the driving wheel.
The utility model has the advantages that:
Driving one end that cylindrical grinder (cylindricalo grinding lathe) circumference drives rod member is the circular cone stage body, and during the workpiece grinding, the workpiece circular-rotation adopts the circular cone rod member to drive.Be used for cylindrical grinder and drive workpiece and rotate, can improve the precision of cylindricity after the grinding of Fine major axis.
When the circular cone drive rod drives workpiece rotating, produces an axial force, make between workpiece and the cutting abrasive wheel and remain vertical, the raising grinding accuracy.
Description of drawings
Fig. 1 is operation principle schematic diagram of the present utility model.
Mark among the figure: driving lever 1, chuck 2, top 3, headstock 4, tailstock case 5, workpiece 6 to be ground, emery wheel 7, direction of rotation A.
The specific embodiment
With reference to shown in Figure 1, a kind of circular cone rod member drives positioning tool, such as the driving lever 1 among Fig. 1, it is a rod shaped structure, the one end is the circular cone shape body of rod, the other end is a cylindric body of rod, and an end of the cylindric body of rod is fixed on the upper bottom surface (the upper bottom surface diameter of the circular cone shape body of rod is less than the bottom surface diameter) of the circular cone shape body of rod, the coning angle of the frustum of a cone is 15 ° ± 30 '.
With reference to shown in Figure 1, a kind of cylindrical grinder, comprise the headstock that is provided with driving wheel, tailstock case, driving lever (or being referred to as shift fork) 1 and the chuck 2 that are oppositely arranged, on the adjacently situated surfaces of headstock 4 and tailstock case 5, be relatively set with top 3, two ends of top and cylindric workpiece 6 to be ground connect, workpiece to be ground is by top location
Driving lever is a rod shaped structure, and the one end is circular cone shape, and the other end is cylinder.Chuck one end is clipped on the workpiece to be ground, and the other end amplexiforms mutually with the circular cone shape body of rod of driving lever, and namely driving lever forms a conical drive rod; The column connecting-rod head of driving lever is fixed on the driving wheel.The employed raw material of driving lever are No. 45 steel or steel alloy.The coning angle of the frustum of a cone is 15 ° ± 30 '.
Adopt above-mentioned cylindrical grinder, can improve the precision of cylindricity after the grinding of Fine major axis;
Illustrate:
[workpiece]: slender axles; [headstock, tailstock case]: two bed casees that refer to cylindrical grinder; [driving lever]: axial circular cone backstay; [chuck]: be that an end is with the fixed bar of clip; [top]: be used for left and right two end fixation workpieces.
Operation principle:
Workpiece to be machined (workpiece to be ground) is clamped in headstock, the tailstock case middle (top location) of cylindrical grinder, chuck 2 is fixed with workpiece and is rotated clockwise with workpiece, driving lever 1 is the setting circle frustum shape bar that an end has 15 ° ± 30 ' cone angle for angle, be installed in (driving wheel) on the headstock rotating disc, after lathe was opened, driving lever 1 conical surface contacted and drives workpiece and rotates clockwise the realization grinding with fixed bar.Because driving lever 1 conical surface and chuck 2 cylindricals present and contact, at work, driving lever 1 namely promotes chuck 2 and does and turn clockwise, and produces simultaneously a motive force of direction left, make the top close contact that remains between workpiece and headstock, workpiece keeps vertical constantly with 7 on emery wheel; Avoid causing workpiece and emery wheel out of plumb because the workpiece that the machine tool hydraulic shakiness causes can not overlap fully with top, affect the cylindricity of workpiece processing.
Effect:
Improve by easy frock, can improve grinding cylindricity precision more than 10 times.
