Utility model content
In order to overcome the operation of must manually participating in the overall process of prior art, the shortcoming that hand labor intensity is large, the utility model provide a kind of can automatic grinding, reduce the tooth axle class centre bore lapping device of hand labor intensity.
Tooth axle class centre bore lapping device, comprises base, and base is provided with for the workpiece support of workpiece to be processed is installed, and lays respectively at left grinding mechanism and the right grinding mechanism of workpiece support both sides, and the driving mechanism that drives workpiece rotation during porting;
The both sides of workpiece support are respectively equipped with left plate and the right plate that sets up workpiece rotating shaft, are respectively equipped with the installing hole coordinating with changing of workpieces shaft clearance on left and right side plate;
Left grinding mechanism and right grinding mechanism comprise respectively grinding head and for the grinding base of grinding head is installed, left grinding base is fixed on base, right grinding base is connected with base by line slideway, and right grinding base is connected with the dynamical element that promotes its left and right translation, and dynamical element is fixed on base; Left grinding head and right grinding head centering, left and right grinding head respectively with two end in contact of workpiece rotating shaft.
Further, driving mechanism comprises motor and is fixed on the driving gear on motor output shaft, driving gear and the engagement of workpiece tooth portion.
Further, the retaining element of line slideway is fixedly connected with base, and sliding members is fixedly connected with right grinding base, and the output shaft of sliding members and dynamical element is fixed.
Further, right grinding base is provided with the burring mechanism of rejecting surface of the work burr, and burring mechanism is by burring knife, and tool rest and knife bar form; Tool rest has the fixed part that is fixed on right grinding base and the moving part that knife bar is installed, and between fixed part and moving part, is provided with spring.
Further, knife bar is fixedly connected with moving part, and knife bar has extension, and holder is provided with the through hole that allows extension to insert and slide in it, and the afterbody of extension is provided with the limited block that stops knife bar disengaging fixed part; Spring housing is connected to extension.This limited block is the nut that diameter is greater than through-hole diameter.
?the utility model only needs manually workpiece to be arranged on workpiece and makes seat above, and porting and deburring complete by automation equipment, and without manually participating in the overall process, labour intensity is low, has the automated production of being suitable for, the advantage that production efficiency is high.
