Abstract
A projection welding process method for an integrated claw pole and a fan assembled on a generator rotor is characterized by comprising the following steps: the end face of the claw pole or the contact face of the fan and the claw pole is provided with a plurality of salient points, a thermoplastic plastic framework coil is arranged between two claw poles pressed on a shaft by the claw pole, two annular electrodes are respectively pressed on the front fan and the rear fan which are arranged on the end faces of the two claw poles, the salient points are simultaneously heated to form a welding core by pressurization and electrification, and the front fan and the rear fan are welded into a whole with the claw pole at one time. Compared with the prior art, the invention solves the difficulty of welding thin and thick parts, and can firstly load plastic insulating materials and coils between the claw poles for welding, thereby reducing a large number of working procedures and processing time, saving materials and energy, having no indentation or burn on the welding surface, and being firm and reliable.
Description
The present invention relates to a kind of salient point welding technique, the process that a plurality of small salient points of particularly a kind of thin plate and slab weld simultaneously.
To be connected with fan mainly be to adopt riveted joint or screw to the pawl utmost point of generator amature in the prior art.This kind assembly method, relating to will be with many equipment, clamping apparatus and operating personnel, and the production cycle is long, also cannot say for sure to demonstrate,prove its concentricity and flatness simultaneously.Generator fan when high speed rotating easily produces loosening, and the balance that influences its rotor increases the noise of generator.
In " exploration of generator claw pole and fan spot welding " literary composition of the first phase in 1997 " the accurate manufacturing technology of aviation " publication, speak of the pawl utmost point and adopt spot welding to replace complicated riveted joint or the affixed technology of screw with being connected of fan.Spot welding is to put one by one to carry out.Though this kind method has solved the firm problem that fan is connected with the pawl utmost point, but cannot say for sure to demonstrate,prove the concentricity and the flatness of fan.And solder joint is big, and the power of consumption is big, also must carry out electroplating processes after having welded and prevent corrosion.Carry out the assembling of whole rotor at last, easy damaged fan and coating when press-fiting, and the slip ring lead-out wire is connected and welding with lead-out wires of coil is bad, can influence its quality.
The purpose of this invention is to provide a kind of reduction energy resource consumption, reduce manufacturing procedure, after generator claw pole, coil and axle assembled, the forward and backward fan while and the pawl utmost point adopted the process of a projection welding nucleation of a plurality of salient points welding.
The objective of the invention is to realize: even a plurality of small salient points of distribution making on 1 millimeter fan board and face that the pawl utmost point contact by following scheme, or evenly distribute on greater than 20 millimeters the extreme face of thick pawl and make a plurality of small salient points, the effective depth that designs and produces salient point is the 0.2-0.45 millimeter.Welding electrode adopts and fan material has the copper-based material of potential difference to make.The welding electrode head is a planar annular, guarantees the effective area that contacts with the fan board face.Generator shaft has press-fited the pawl utmost point, two pawl interpolars be equipped with coil and with the thermoplastics skeleton of pawl utmost point insulation or the skeleton of other insulating material, connect slip ring lead-out wire and lead-out wires of coil.Pawl utmost point both ends of the surface are laid forward and backward fan, and the relative position of the fan and the pawl utmost point is guaranteed by special fixture.Two planar annular electrodes are pressed on respectively on the forward and backward fan board, the planar annular electrode should with the salient point correspondence.Adopt the above welding machine of 80KVA during welding, welding pressure 0.4-0.6MPa, 0.6-1.2 second weld time, more than the welding current 25000A, resistance welded is carried out in each salient point zone of energising heating simultaneously, forms solid solution weldering nuclear.
The present invention compared with prior art has the following advantages: the generator amature pawl utmost point, thermoplastics insulation framework, coil and axle can be joined by advanced luggage, again forward and backward fan being placed in two pawls extremely once is welded into simultaneously, reduced manufacturing procedure, operation easily, improve work efficiency, reduced energy resource consumption.Adopt multiple spot transient heating simultaneously, salient point place nucleation is fast, plastic insulation skeleton and coil can pack into earlier pawl extremely in the middle of, welding again.Can guarantee the concentricity and the flatness of fan, the pawl utmost point and axle.
Describe in further detail below in conjunction with embodiment: on the flat board of fan and face that the pawl utmost point contacts, make a plurality of salient points that are evenly distributed.The effective depth of salient point is preferably 0.3 millimeter.The seam nucleation is qualified, and the fan and the pawl utmost point are fitted tight.Before fan and the welding of the pawl utmost point, press-fit a pawl utmost point pressing on the axle of slip ring, the centre bore of coil block plastic skeleton is contained on the pawl pole piece axle, press-fit another pawl utmost point then, the end face of two pawl pole piece axles is fitted, lead-out wires of coil with weld after the slip ring lead-out wire is connected.With the special tool anchor clamps forward and backward fan is fixed on the appropriate location of the two pawl utmost points, two planar annular electrodes are pressed in respectively on the forward and backward fan plane.Adopt the above welding machine of 80KVA, welding pressure is 0.4-0.6MPa, and 0.6-1.2 second weld time is more than the welding current 25000A.Formation weldering nuclear is welded at a plurality of salient points of energising heating place simultaneously, and the front and back fan also is welded in the extreme face of pawl simultaneously, and planar annular electrode and fan contact-making surface do not have burn and obvious impression.
Use the generator amature of multiple projection welding process of the present invention, temperature be 90 ℃ ± 2 ℃ and rotating speed be 14000 rev/mins environment down do endurance test in 350 hours any problem does not appear.
