Abstract
The invention relates to a crank abrasion processing method, wherein it is characterized in that: abrasive wheel is mounted on vertical track; the track is on the horizontal track; the main shifter ofcrank is mounted on one rotation axle; the horizontal track, vertical track and rotation axle are connected by digit-control system; first rotating the rotation axle, using abrasive wheel to abrade the round of main shifter; moving abrasive wheel to eccentric shifter to rotate with rotation axle; the abrasive wheel driven by horizontal track and vertical track moves along the eccentric shifter toabrade the round of eccentric shifter, to process the crank; when processing the main shifter and eccentric shifter, the central height of abrasive wheel is same as the central height of shifter. Theinvention has high efficiency and accuracy.
Description
Technical field
The invention belongs to machining methods, specifically is a kind of crankshaft grinding processing method.
Background technology
Usually use bent axle in machine driving, bent axle adding necessary multiple clamping grinding in man-hour, cause grinding efficient low, and machining accuracy is also wayward owing to a lot of gears are arranged not on same axis.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, the crankshaft grinding processing method of a kind of advantages of simple, the different gears of employing numerical control device energy servo-actuated machining crankshafts is provided.
Technical scheme of the present invention is as follows:
A kind of crankshaft grinding processing method is characterized in that: an emery wheel is contained on the vertical guide rail, and vertical guide rail is contained on the horizontal guide rail, and the main file of bent axle is contained on the rotating shaft, and horizontal guide rail, vertical guide rail, rotating shaft are linked by digital control system; Rotate rotating shaft earlier, with the cylindrical of wheel grinding bent axle main file; Emery wheel is moved to eccentric shelves, eccentric shelves rotate with rotating shaft again, and with eccentric shelves motion, the cylindrical of the eccentric shelves of grinding can grinding go out bent axle to emery wheel under horizontal guide rail, vertical guide rail drive.
The present invention is at the main file of grinding bent axle during with eccentric shelves, and the height at emery wheel center is consistent with the gear axle centre-height of institute grinding all the time.
The present invention is owing to be contained in emery wheel on horizontal guide rail, the vertical guide rail, and control by digital control system with rotating shaft, the emery wheel centre-height is consistent with the gear axle centre-height of institute grinding all the time, the main file cylindrical of grinding bent axle and eccentric shelves cylindrical are realized the grinding of bent axle under the digital control system interlock.This method grinding efficiency height, and can improve crank processing precision.
Description of drawings
Fig. 1 is a processing method schematic diagram of the present invention.
Fig. 2 is the crankshaft structure schematic diagram.
Fig. 3 is that emery wheel is at the eccentric shelves of diverse location grinding schematic diagram.
The specific embodiment
As shown in Figure 1, 2, a kind of crankshaft grinding processing method is characterized in that: an emery wheel 1 is contained on the vertical guide rail 2, and vertical guide rail 2 is contained on the horizontal guide rail 3, the main file 4 of bent axle is contained on the rotating shaft, and horizontal guide rail 3, vertical guide rail 2, rotating shaft are linked by digital control system; Rotate rotating shaft earlier, with the cylindrical of emery wheel 1 grinding bent axle main file 4; Emery wheel 1 is moved to eccentric shelves 5, eccentric shelves 5 rotate with rotating shaft again, and with eccentric shelves 5 motions, the cylindrical of the eccentric shelves 5 of grinding can grinding go out bent axle to emery wheel 1 under horizontal guide rail 3, vertical guide rail 2 drive.
As shown in Figure 3, the present invention is the main file 4 of grinding bent axle and eccentric shelves 5 o'clock, and the height at emery wheel 1 center is consistent with the gear axle centre-height of institute grinding all the time.
Among Fig. 3, suppose that the eccentric throw between eccentric shelves 5 and the main file 4 is L, the diameter of main file is H, the diameter of eccentric shelves is W, and grinding wheel radius is R, is the origin of coordinates with rotating shaft center's point, with horizontal direction and perpendicular to the rotating shaft direction is X-axis, set up coordinate system, the coordinate of establishing the emery wheel central point is x, y, and the main file central axis is vertical with X-axis, the angle of eccentric shelves central axis and X-axis is α, then the wheel grinding bent axle meets following rule: the outer bowlder of emery wheel 1 grinding bent axle main file 4, x=R+H/2, y=0; The outer bowlder of the eccentric shelves 5 of wheel grinding, emery wheel 1 moves with horizontal guide rail 3, vertical guide rail 2 under digital control system control, when α=0～90 °, x=Lcos α+W/2+R, y=Lsin α; When α=90～180 °, x=-Lcos (180 °-α)+W/2+R, y=Lsin (180 °-α); When α=180～270 °, x=-Lcos (α-180 °)+W/2+R, y=-L sin (α-180 °); When α=270～360 °, x=Lcos (360 °-α)+W/2+R, y=-Lsin (360 °-α), can the eccentric shelves of grinding cylindrical.
