Description
Technical field
The present invention relates to the processing technology of a kind of hybrid excitation generator with the pawl utmost point.
Background technology
Along with people are more and more higher to the requirement of the comfortableness of car, also more and more higher to the power requirement of generator; People require also more and more to pay attention to the oil consumption of car simultaneously, so automobile main frame maker is more and more harsher to the weight of each parts.Based on the light-weighted requirement of generator high power, present a lot of generator plants hybrid excitation generator that begins one's study, the difference of hybrid excitation generator and common generator is mosaic magnet between the pawl utmost point of the front and back of generator amature, greatly increase the magnetic property of the pawl utmost point, thereby increased greatly power output and the efficiency of generator.Yet the pawl of existing generator amature is extremely gone up and is not specifically designed to the standing groove of placing permanent magnet, can cause like this permanent magnet position unstable, and affect the performance of product; And also neither one positioning datum of the assembling of the front and back pawl utmost point, can't realize the automation of assembling, also wasted human resources when affecting production efficiency.
in addition, owing to having inlayed permanent magnet between the pawl utmost point of front and back, if the assembly technology of rotor still adopts existing technique, centered by axle, the cylindrical of processing rotor, will certainly produce a large amount of iron filings and be adsorbed to permanent magnet surfaces, because the magnetic of permanent magnet is high, iron filings can't be removed totally, can cause rotor when running up, effect due to centrifugal force, the risk that iron filings are thrown out of, thereby cause the even risk of breaking out of fire of generator short circuit, therefore the processing technology of hybrid excitation generator rotor can not the car rotor outer circle, the dimensional tolerance of rotor outer circle and the requirement of beating must lean on the processing technology of the pawl utmost point and the assembly technology of rotor to guarantee.
Summary of the invention
The objective of the invention is to overcome the defect that prior art exists, provide a kind of have the magnet standing groove and be used for to guarantee before and after the uniformity of width of each magnet groove of forming after the assembling of the pawl utmost point and the hybrid excitation generator of positioning spline of being convenient to assembly automation with the processing technology of the pawl utmost point, make and adopt the pawl utmost point of this processing technology processing to need not to reprocess rotor outer circle after being assembled into rotor.
The technical solution adopted for the present invention to solve the technical problems is: a kind of hybrid excitation generator with the processing technology of the pawl utmost point, has following processing step:
A, the hot finish forge of employing or warm forging technique are made pawl utmost point blank;
B, magnetic annealing: forging is put into annealing furnace anneal;
C, cold-finish: the yoke periphery of the cold-finish pawl utmost point, baseplane, interior inclined-plane and pawl utmost point periphery, the pawl of the cold-finish simultaneously utmost point refers to side;
D, brill endoporus;
E, right boring endoporus: Vehicle Processing fan plane and right boring endoporus: take pawl utmost point baseplane as positioning datum, yoke periphery with the scroll chuck clamp jaw utmost point, adopt turn-milling complex machining center time processing fan plane, right boring endoporus, Vehicle Processing pawl utmost point periphery and mill the processing positioning spline, the axiality of guaranteeing pawl utmost point periphery and endoporus is 0.02mm, and the perpendicularity of fan plane and endoporus is 0.03mm;
F, car yoke end face:, take finished fan plane as location, adopt the installation way of elastic central spindle's tensioner endoporus, Vehicle Processing yoke end face, the perpendicularity of guaranteeing yoke end face and endoporus is 0.03mm, the depth of parallelism of fan plane and yoke end face is 0.03mm;
G, mill the pawl utmost point and refer to the magnet standing groove of two sides: with endoporus and one of them positioning spline location, hydraulic compression yoke end face, adopt the mode that installs numerical control turntable on three axle machining centers additional, after processing a bar magnet standing groove, panoramic table turns over certain angle, then process second magnet standing groove, until all magnet standing groove process finishing are made finished parts.
Beneficial effect of the present invention: the invention solves the defect that exists in background technology, adopt the pawl that this processing technology is made to have magnet standing groove and positioning spline; And adopt the pawl utmost point that this processing technology is made to need not to reprocess rotor outer circle after being assembled into rotor, thereby avoided the even risk of breaking out of fire of generator short circuit.
