Description
Technical field
The invention belongs to Crankshaft Machining technical fields, and in particular to a kind of crankshaft processing technology.
Background technique
Crankshaft is an important part in piston-mode motor.Crankshaft-and-connecting-rod, piston etc. form crank connecting link together
Mechanism.When engine operation, the downward thrust of piston passes to crankshaft through connecting rod, and back and forth transporting to for piston is become bent from crankshaft
Rotary motion of the axis around itself axis, and outside output power, the power train through automobile drive automobile.Add to improve crankshaft
Working medium amount and production efficiency, reduce the early investment of production line, and critical process is used domestic using import equipment and other process
A kind of novel process scheme that equipment combines.
Summary of the invention
The technical problems to be solved by the invention are in view of the above shortcomings of the prior art, to provide a kind of Crankshaft Machining work
Skill, it can effectively improve production efficiency and reduce production line early investment.
The technical scheme adopted by the invention is that: a kind of crankshaft processing technology, comprising the following steps:
(1) Milling Centre hole and turning crankshaft concentric reducer and trunnion；
(2) machining of oil hole carries out the punching of straight oilhole and inclined oil hole of air using brill oilhole special plane on workpiece, while to straight oil
Hole and inclined oil hole of air carry out chamfering；
(3) mid frequency induction hardening carries out mid frequency induction hardening using trunnion, connecting rod neck and major part of the mid frequency induction hardening machine to workpiece, makes
Use Self-tempering；
(4) both ends of the hole system processes, using horizontal Machining centers to the small head bore of workpiece, bottom-end bearing hole, flywheel hole system, letter
Dialer hole system, keyseat and flat carry out roughing；
(5) thrust surface, trunnion, connecting rod neck, major part and microcephaly are refined；
(6) it detects a flaw, whole flaw detection is carried out to workpiece using magnaflux；
(7) it cleans, Integral cleaning is carried out to crankshaft using full-automatic intermediate cleaning machine.
Preferably, carrying out detection measurement after fine grinding major part and microcephaly.
The beneficial effects of the present invention are: the present invention has rational design, can be shortened processing compared to conventional crankshafts production technology
Process flow reduces lathe quantity, reduces the labor intensity of operator, to reduce the cost of production, improve production
Efficiency.
Specific embodiment
Below in conjunction with specific embodiment, invention is further described in detail.
Embodiment
Crankshaft processing technology provided in this embodiment, comprising the following steps:
(1) Milling Centre hole and turning crankshaft concentric reducer and trunnion；
(2) machining of oil hole carries out the punching of straight oilhole and inclined oil hole of air using brill oilhole special plane on workpiece, while to straight oil
Hole and inclined oil hole of air carry out chamfering；
(3) mid frequency induction hardening carries out mid frequency induction hardening using trunnion, connecting rod neck and major part of the mid frequency induction hardening machine to workpiece, makes
Use Self-tempering；
(4) both ends of the hole system processes, using horizontal Machining centers to the small head bore of workpiece, bottom-end bearing hole, flywheel hole system, letter
Dialer hole system, keyseat and flat carry out roughing；
(5) thrust surface, trunnion, connecting rod neck, major part and microcephaly are refined；
(6) it detects a flaw, whole flaw detection is carried out to workpiece using magnaflux；
(7) it cleans, Integral cleaning is carried out to crankshaft using full-automatic intermediate cleaning machine.
In above-described embodiment, detection measurement is carried out after refining major part and microcephaly.
The present invention has rational design, can be shortened processing process compared to conventional crankshafts production technology, reduces lathe quantity,
The labor intensity for reducing operator improves the efficiency of production to reduce the cost of production.
