The specific embodiment
The processing method of more eccentric shaft of the present invention, referring to shown in Figure 1, this method comprises the steps:
(1) datum axis of setting more eccentric shaft, axis and datum axis superposed part are exactly benchmark shelves 1, and superposed part is not eccentric shelves 2, the axis of eccentric shelves and the distance of datum axis are exactly eccentric throw, and as shown in Figure 1, different eccentric shelves have different eccentric distance e 1, e2, e3;
(2) lengthening end 3 is set respectively at the two ends of more eccentric shaft, the axis of described lengthening end 3 overlaps with described datum axis;
(3) put balance weight in each eccentric shelves 2 outside of described more eccentric shaft, the balance portion of described balance weight is towards the eccentric opposite side of described eccentric shelves, the cylindrical of each benchmark shelves 1 that axis on the described more eccentric shaft is overlapped with described datum axis is processed afterwards, pulls down described balance weight after the completion of processing; The balance weight role makes whole more eccentric shaft keep balance when rotating.Because the weight of more eccentric shaft is very heavy, inertia was very big when eccentric shelves rotated, and can cause whole more eccentric shaft to produce violent vibration when rotating, and in order to offset this vibration, on eccentric shelves balance weight was installed;
(4) put in the outside of described two lengthening ends 3 and the corresponding eccentric bushing of eccentric shelves to be processed, the outside at described each benchmark shelves and other eccentric shelves puts balance weight, the balance portion of balance weight is towards the side of these eccentric shelves to be processed with respect to these benchmark shelves on the described benchmark shelves, the balance portion that described other eccentric shelves are gone up balance weight is towards the side of these eccentric shelves to be processed with respect to this other eccentric shelves, afterwards with the axis of eccentric shelves to be processed as the processing axis, cylindrical to these off-centre shelves is processed, and pulls down eccentric bushing after the completion of processing; The effect of balance weight is to be used for eliminating violent vibration equally;
(5) the lengthening end at removal two ends obtains more eccentric shaft.
The step of lengthening end was set respectively at the two ends of more eccentric shaft in described (2) step, was just to forge at the two ends of more eccentric shaft the lengthening end is arranged when forging more eccentric shaft.
At the two ends of more eccentric shaft the step that lengthening is held being set respectively in described (2) step, perhaps also can be after forging is not provided with the more eccentric shaft of lengthening end, adopts the method for welding to extend and holds the two ends that are connected to described more eccentric shaft.
Described lengthening end 3 is cylindrical.Described cylindrical lengthening end 3 is provided with keyway 4.
Perhaps described lengthening end is a column, and its cross section or be equilateral triangle perhaps is a square, perhaps is regular polygon.
If eccentric throw difference of each eccentric shelves repeated for (4) step after the step of finishing for (4) step, and change the corresponding eccentric bushing of eccentric shelves with other eccentric throw, the off-centre of other eccentric throw grade is processed.
The present invention also provides a kind of employed balance weight of processing method as above-mentioned more eccentric shaft, as shown in Figure 2, comprise balance portion 5 and fixed part 6, described balance portion 5 has certain quality, make whole more eccentric shaft when rotating, keep balance, after described balance portion 5 and fixed part 6 splicings were fixing, the inner edge of the inner edge of balance portion 5 and fixed part 6 was formed the shape of a cylinder.The cylinder that the inner edge of described balance portion 5 and the inner edge of fixed part 6 are formed grade is tightly embraced off-centre, and anti-sliding stop.
The present invention also provides a kind of employed eccentric bushing of processing method as above-mentioned more eccentric shaft, as shown in Figure 3 and Figure 4, one end of described eccentric bushing is respectively arranged with lengthening stomidium 7, the other end is provided with machining hole 8, the axis of described lengthening stomidium 7 is parallel with the axis of described machining hole 8, the distance of the axis of the axis of described lengthening stomidium 7 and described machining hole 8, equate that with the distance of the datum axis of the axis of eccentric shelves on the more eccentric shaft to be processed and more eccentric shaft the shape in described lengthening stomidium 7 cross sections holds the shape in 3 cross sections consistent with the lengthening of described eccentric shaft.
In setting-up eccentricity cover, as shown in Figure 5, the lengthening stomidium of eccentric bushing 10 is enclosed within on the described lengthening end, and the axis of lengthening stomidium is overlapped with reference axis, the dead in line of the axis of machining hole and off-centre to be processed grade.The cross section of described lengthening end is if regular polygon, and the cross section of described lengthening stomidium also is a regular polygon, and regular polygon can overlap axis accurately, and can not make axis produce skew because of twisting.If the cross section of lengthening end is circular, the stomidium that extends so also is a circular hole, and for accurate location, the lengthening end is provided with keyway, and also is provided with keyway in the lengthening stomidium, by key is set, makes eccentric bushing also can not twist when installing inside.Afterwards thimble can be installed on machining hole, serve as the processing axis with the axis of machining hole, and eccentric shelves are processed.Eccentric shelves for different need different eccentric bushings is installed, and the machining hole axis is to equate with the eccentric throw of eccentric shelves with the distance of lengthening stomidium axis on the eccentric bushing.
On the cross section perpendicular to axis of described eccentric bushing, the rectilinear direction at the line place in the center of circle of the center of circle of the above stomidium that extends and described machining hole serves as vertical with eccentric bushing, and the center of circle of lengthening stomidium is last, and the center of circle of machining hole is following, and described eccentric bushing is about this vertical straight line symmetry; With the center of circle by machining hole and perpendicular to the straight line of described vertical straight line is boundary, and the lower mass of eccentric bushing is greater than described eccentric bushing top quality.
If adopt this eccentric bushing of dissymmetrical structure up and down, cylindrical in (4) step of the present invention to eccentric shelves carries out in the processing steps, just needn't on each benchmark shelves and other eccentric shelves, balance weight be installed, directly offset processing and make issuable vibration with the up and down asymmetric quality of eccentric bushing.So not only simplify step, but also can reduce the power consumption that adds man-hour.
In sum, balance weight provided by the present invention and eccentric bushing, it is simple in structure, be easy to making, and be easy to reach precision, and adopted the processing method of the more eccentric shaft of balance weight and eccentric bushing than higher, its step is simple, can conveniently produce the higher more eccentric shaft of precision.
