Abstract
The invention discloses a processing technology of an eccentric shaft, which comprises the following steps: the surface hardness reaches HRC 30-40; secondly, rough turning: processing two end faces of the blank, wherein the length of the blank reaches the size required by the design, the two end faces are exposed to light, and a central hole is drilled; thirdly, finish turning: processing the excircle of the shaft, and processing all excircles into the size required by design; fourthly, fine milling: milling a plane on the shaft body according to the design requirement; fifth, surface treatment: removing burrs and blackening; sixthly, packaging and warehousing: coating antirust oil on the eccentric shaft, and individually packaging by using an air bubble bag for warehousing. By the mode, the eccentric shaft can be rapidly, simply and conveniently machined, machining efficiency is improved, labor cost is reduced, and productivity is improved.
Description
Technical field
The present invention relates to machining process, more particularly to a kind of eccentric axis processing technique.
Background technology
Traditional eccentric shaft processing method has following several, a kind of method is the method in the two ends centering of axle and eccentric centre bore using jig boring machine, it is impracticable in the case of eccentric throw very little, the eccentric throw precision of eccentric shaft depends on the precision of institute's centering and eccentric centre bore, once centre bore and eccentric central hole location determine to have adjusted again；Another is that eccentric work piece is processed on tri-claw disk or four paws disk, and this precision of method is low, and often processing a workpiece will reposition, and efficiency is low；Also a kind of processing method is, in axle two ends centering, to be completed with crankshaft grinding machine grinding, and machining accuracy is high, but needs special crankshaft grinding machine, and cost is higher.
The content of the invention
The present invention solves the technical problem of a kind of eccentric axis processing technique is provided, processing eccentric shaft that can be fast and convenient improves processing efficiency reduction labour cost, improves production capacity, is also suitable for producing in enormous quantities.
In order to solve the above technical problems, one aspect of the present invention is：A kind of eccentric axis processing technique, first, heat treatment are provided：Case hardness is set to reach HRC30 ~ 40；Second, it is rough turn：Two end faces of turned blank, length reaches the size of design requirement, and light, and centering are met personally in two ends；3rd, smart car：Process axle cylindrical, size of all Excircle machinings into design requirement；4th, finish-milling：According to design requirement on axle body the plane of milling one；5th, surface treatment：Deburring simultaneously does blackening process；6th, packaging and storage：Antirust oil is applied on eccentric shaft, with the independent packaging and storage of bubble bags.
Preferably, the 3rd step smart car includes the first smart car, the second smart car, the 3rd smart car and the 4th smart car；Each is cylindrical for first finishing processing；The big axial end of second finishing processing reaches design size；3rd smart car is fixed with eccentric fixture, processes eccentric excircle；The 4th small axial end of finishing processing makes axle reach design size length.
The beneficial effects of the invention are as follows：The present invention can be fast and convenient processing eccentric shaft, processing cost is low, improves processing efficiency reduction labour cost, improves production capacity.
