Waste.
The present invention is to be achieved through the following technical solutions:
A kind of band damping platform rotor blade processing method, comprising the following steps:
Step 1, parts to be processed is packed into first set tooling to clamp, is sent into lathe；Lathe calls gauge head to part feature
Point is detected, and is continued to run if meeting setting requirements, otherwise lathe is out of service；When meeting setting requirements, carry out such as
Lower processing: milling intake and exhaust side edge, milling listrium and blade switching R, milling leaf basin side damping platform surrounding and each face, milling leaf
Back side damps platform surrounding and each face and milled part datum level；
Step 2, part is changed the outfit to second set of tooling and is clamped, be sent into lathe, processed as follows: milling both ends technique is convex
Platform, milling tenon end face and the edge angle R, milling tenon side, milling tenon head profile and its angle R and milling blade tip.
Preferably, in step 1, when machine tooling intake and exhaust side edge and listrium are with blade switching R, added using automatic amendment
The method of engineering sequence is processed.
Further, it is processed using the method for automatic amendment processing program, specifically: the measurement system based on lathe
System, basketry work step call lathe gauge head, detect to be processed and non-processing position, extract feature geometries, form point
Principle opinion numerical control program is modified by cloud by mathematical operation.
Preferably, in step 2, after being sent into lathe, lathe calls gauge head to detect part datum level, and amendment part adds
Work zero point.
Preferably, in step 1 and step 2, transport establishment is all made of by part and is sent into lathe.
Preferably, transport establishment is manipulator.
Preferably, lathe is the five-axis machine tool with gauge head.
Preferably, further includes: step 3, part is transported to marking machine and carries out coded markings.
Further, further includes: step 4, all sizes of part are measured.
Further, part is sent to white light measuring machine, all sizes of part is measured, measurement data carries out hard
Disk backup.
Compared with prior art, the invention has the following beneficial technical effects:
Lathe of the present invention calls gauge head to detect part feature point, compares with theoretical model, thus to part
Quality condition is prejudged in advance, is met setting requirements and is continued to run processing, rejects to rejected part, therefore the present invention
With self-diagnostic function, only satisfactory part is processed, undesirable part is not processed, avoid resource and when
Between waste, improve working efficiency, improve product qualification rate, improve product quality.Meanwhile in step 1 and 2, by part institute
There is size completion, saves a process more than 20, further increase processing efficiency；The present invention is right by selecting reasonable fixture, lathe
Conventional processing routes optimize, and improve the accuracy of manufacture, ensure that the product qualification rate and quality of precision forged blade, reduce part and add
Work process shortens delivery cycle, solves in the prior art the problems such as part qualification rate is low, manufacturing procedure is long, the production cycle is long.
Further, when machine tooling intake and exhaust side edge and listrium are with blade switching R, using automatic amendment processing program
Method, have adaptation function, not only allowed working position and non-processing position transition round and smooth, but make working position meet design want
It asks, can be further improved product quality and consistency.
Further, lathe detects part datum level, and amendment processing zero point has self-repair function.
Further, after receiving instruction using transport establishment, instead of the frock clamp of clamping parts is manually sent into lathe,
With from perceptional function, operator's labor intensity is reduced, processing efficiency, positioning accuracy, homogeneity of product and quality are improved；Transport
The use of mechanism improves the intelligence degree of production line.
Further, all dimensional measurements are carried out to part using white light measuring machine, more set special measuring tools can be saved
It uses, improves detection efficiency；Measurement data carries out hard disk backup, carries out paperless office, saves resource, while convenient for processing
The data of size are analyzed.
