A kind of rotor automatic assembly line
Technical field
The present invention relates to a kind of automatic assembly line, particularly a kind of automatic assembly line for rotor.
Background technology
Motor is mainly made up of rotor and stator, is to realize the important device that electric energy changes to mechanical energy, is many automatic
Disguise the power source put, be widely used in all trades and professions.Rotor is made up of rotating shaft and rotor core, its production process master
To include rotating shaft and be pressed into iron core, iron core is cylindrical and the cylindrical rolling paint of iron core etc. for processing;The outer bowlder of iron core is processed, mainly passes through numerical control lathe
Bed carrys out the cylindrical of turning rotor iron core, and its process time is shorter, it is necessary to which workman completes rotor typically below 10 seconds
Loading and unloading and clamping;And rotor is widely used, China is in great demand to rotor.
Current rotor is primarily present following limitation in process:(1) automaticity is low, processing efficiency
It is low.Although there is the equipment for automating loading and unloading and clamping in the market, most equipment is realized using manipulator
The loading and unloading of rotor and clamping, the long clamping time have had a strong impact on rotor processing efficiency, and manipulator into
This is higher, therefore the loading and unloading of rotor and clamping major part are completed by artificial, cause process automation
Degree is low, inefficient.(2) labor strength is big, there is potential safety hazard.In rotor process, due to processing
Time is very short, and workman needs frequently to carry out loading and unloading and clamping manually, is directly contacted with lathe, labor intensity is larger,
Serious potential safety hazard is there is in the prolonged course of work.(3) advertise for workers difficult, labor shortage.When rotor is processed
One numerically controlled lathe needs to be equipped with a workman, and the demand of rotor is very big, therefore the processing of rotor needs greatly
Measure workman;As Chinese labour force cost is gradually increasing, the labour intensive profession emergence recruitment such as rotor processing hardly possible,
Situations such as labor shortage.
