Description
Technical field
The present invention relates to a kind of processing methods of connecting shaft, and in particular to a kind of processing of the connecting shaft for lifting tool
Method.
Background technique
Connecting shaft is an important component of lifting tool, which is Step Shaft, processing difficulties are as follows: original process scheme
The component is rough forging, and the blank manufacturing cycle is long.The component machining allowance of original process scheme is big, long processing time.
Summary of the invention
For the present invention in view of the shortcomings of the prior art, providing one kind can be shortened the manufacturing cycle, that improves intensity is used for lifting tool
Connecting shaft processing method.
The technical scheme is that
A kind of processing method of the connecting shaft for lifting tool, it includes
Step 1: preparing blank: end cap blank uses plate, and cylinder blank uses tubing；
Step 2: the outer circle of turning end cap blank, inner hole, both ends of the surface and welding chamfering on lathe；
Step 3: the outer circle, both ends of the surface of turning cylinder blank and welding chamfering on lathe；
Step 4: the good end cap of vehicle and barrel soldering are integrated；
Step 5: carrying out destressing processing；
Step 6: lathe get on the bus prune stress treated cylinder outer circle and end face it is quasi-；
Step 7: drilling on drilling machine to the end cap of connecting shaft, it is quasi- to bore tapping female bore to cylinder；
Step 8: by each seamed edge rounding, franking is completed the process.
The present invention has the effect that compared with prior art
1, the preparation of blank is improved to plate and tubing by forging, and the stock period is greatly saved.
2, connecting shaft uses tubing, reduces machining allowance, saves the process time of turning.
3, after using welding structure, welding, the processing of destressing defect elimination has been carried out, ensure that the intensity requirement of connecting shaft, has been protected
Product quality and job security are demonstrate,proved.The invention is good through practical application effect.

Specific embodiment
The present invention is described in detail with reference to the accompanying drawings and examples.
Referring to fig. 2 shown in-Fig. 5, a kind of processing method of the connecting shaft for lifting tool, it includes
Step 1: preparing blank: end cap blank uses plate, and cylinder blank uses tubing；
Step 2: the outer circle of turning end cap blank, inner hole, both ends of the surface and welding chamfering on lathe；
Step 3: the outer circle, both ends of the surface of turning cylinder blank and welding chamfering on lathe；
Step 4: the good end cap 1 of vehicle and cylinder 2 are welded as a whole；
Step 5: carrying out destressing processing；
Stress is pruned treated outer circle and the end face of connecting shaft Step 6: getting on the bus in lathe；
Step 7: drilling on drilling machine to the end cap of connecting shaft 1, tapping female bore is bored to cylinder 2；
Step 8: by each seamed edge rounding, franking is completed the process.
Step 2: three and six lathe model C620, the model Z35 of the drilling machine of step 7.
The preparation of blank is improved to plate and tubing by forging, and the stock period is greatly saved.Connecting shaft uses tubing, subtracts
Small machining allowance, saves the process time of turning.After welding structure, welding, the processing of destressing defect elimination is carried out, has been guaranteed
The intensity requirement of connecting shaft, ensure that product quality and job security.
As an embodiment, the size of end cap blank: outside diameter 405mm, diameter of bore 220mm are thick
Degree is 50mm；The size of cylinder blank: periphery diameter is 330mm, internal diameter 230mm, length 545mm.
Step 2 turning end cap outer circle to diameter is 395mm, and turning end cap diameter of bore is 230mm, and turning thickness is extremely
45mm, it is 8 × 45 ° that end cap, which welds chamfering 1-2,.
Step 3 turning cylinder outer circle to diameter is 312mm, and turning cylinder bore is directly 230mm, turning end to cylinder
Body length is 535mm,
The barrel soldering chamfering 2-2 of step 3 is 2-8 × 45 °.It is bored in step 7Hole 1-1, be uniformly arranged；It bores
The threaded hole 2-1 for attacking 6-M12, is uniformly arranged.End cap and cylinder are welding as one by step 4 using electric welding.Referring to Fig. 1 and figure
5, the outside diameter of the end cap for the connecting shaft that step 6 is finally processed is 390mm, and the diameter of bore of end cap is 230mm, phase
Pair the centre distances of two drilling be 350mm, the turning on the periphery that the outer diameter of cylinder 2 is 312mm, forms in step 6
