Abstract
A projection welding process for the integrated claw pole and fan used to assemble the rotor of electric generator features that multiple salient points are arranged on the end surface of claw pole or the contact surface between fan and claw pole, the thermoplastic skeleton coil is installed between two claw poles on shaft, two ring electrodes are respectively pressed on the front and back fans on the end surfaces of two claw poles, and the front and back fans and claw poles are welded together. 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 fix 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, simultaneously difficult its concentricity and the flatness of guaranteeing also.Generator fan when high speed rotating easily produces loosening, and the balance that influences its rotor increases the noise of generator.
The first phase in 1997 " aviation Precision Manufacturing Technology " publication " exploration of generator claw pole and fan spot welding " in the literary composition, is spoken of the pawl utmost point and the riveted joint or the affixed technology of screw that adopt spot welding replacement complexity being connected of fan.Spot welding is to put one by one to carry out.Although this kind method has solved the firm problem that fan is connected with the pawl utmost point, but difficult concentricity and the flatness that guarantees fan.And solder joint is big, and the power of consumption is big, also must carry out electroplating processes after being soldered and prevent corrosion.Carry out at last the assembling of whole rotor, easy damaged fan and coating when press-fiting, and the slip ring lead-out wire is connected connection and welding with lead-out wires of coil, can affect 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, 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 by following scheme: even a plurality of small salient points of distribution making on 1 millimeter fan board and face that the pawl utmost point contact, 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 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 interval, 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, thermoplastic 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, easily operation, improve work efficiency, reduced energy resource consumption.Adopt simultaneously transient heating of multiple spot, salient point place nucleation is fast, plastic insulation skeleton and coil can pack into earlier pawl extremely in the middle of, again welding.Can guarantee the concentricity and the flatness of fan, the pawl utmost point and axle.
Be described in further detail below in conjunction with embodiment: make a plurality of salient points that are evenly distributed at the face that the flat board of fan contacts with the pawl utmost point.The effective depth of salient point is preferably 0.3 millimeter.The postwelding nucleation is qualified, and 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 at the axle that presses slip ring, the centre bore of coil block plastic skeleton is contained on the pawl pole piece axle, press-fit then another pawl utmost point, 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 interval 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.
