Description
Technical field
The present invention relates to electric machine stator iron stack-press device, being specially a kind of chute stator unshakable in one's determination without pulling stack-press device.
Background technology
Flourish along with domestic equipment manufacture, as power unit and performance element, motor is obvious all the more to the trend of safety, high-efficient development, has become the main flow of world's motor demand.
In the large and medium generator of current domestic production, due to stator and rotor fluting and the non-centralized arrangement of winding, magnetic potential of air gap is made to contain harmonic wave in various degree, air-gap field is set up by magnetic potential, so just make air-gap field and non-fully distributes sinusoidally, therefore the induced potential in winding is also not exclusively sinusoidal wave, namely except sine-shaped first-harmonic, also contains series of harmonic.
The existence of harmonic wave increases making the supplementary load loss of generator itself, decrease in efficiency, and temperature rise raises, and has an impact to transmission line and neighbouring electric equipment.
Flume structure stator core can harmonic carcellation effectively, reduces the supplementary load loss of generator itself, raises the efficiency, reduce temperature rise, become the trend of following raising whole motor performance.
Practical, to laminate technology be efficiently meet the key that modern electrical machine manufactures.The quality of stack-press device directly affects labor productivity and the quality of electric machine iron core.Traditional generator stator iron core laminating device comprises rise cartridge type stack-press device and fixing cartridge type stack-press device;
The cartridge type that rises stack-press device utilizes 3 flap-type to rise by cylinder by punching internal diameter tensioner, locates cylindrical unshakable in one's determination, realize skewed slot and laminate by taper key.Its shortcoming is as follows: 1, perpendicularity unshakable in one's determination is poor; 2, be only applicable to the stator core that internal diameter is less than 1m, be not suitable for big-and-middle-sized stator core; 3, angle of bevel ensures indirectly, and quality is wayward.
Fixing cartridge type stack-press device utilizes axle to locate punching internal diameter, by movable taper key location core slots, realizes skewed slot and laminate.Its shortcoming is as follows: 1, tread flaking difficulty, easily pulls iron core, the iron core particularly after welding during tread flaking; 2, the uniform property of skewed slot is poor, and quality is wayward.
Current domestic chute stator iron core laminating device is still in exploration, conceptual phase, is particularly still blank for large and middle size motor flume structure generator stator iron core laminating device.
Summary of the invention
The present invention, in order to easily pull iron core when solving existing generator stator iron core laminating device tread flaking and the uppity problem of quality, provides a kind of chute stator unshakable in one's determination without pulling stack-press device.
The present invention adopts following technical scheme to realize: chute stator is unshakable in one's determination without pulling stack-press device, comprise and laminate base, laminate on base and be provided with column core cylinder, on the outer circumference surface of core cylinder, radial equipartition has the taper groove of some vertical settings, be arranged at intervals with the wedge of its matched in clearance in taper groove and locate taper key, the upper surface of wedge is screwed with the jackscrew that lower end contacts with core cylinder upper surface, and core cylinder inwall is screwed with the fastening bolt fixing with wedge, the outside of location taper key is the helicoidal structure coordinated with stator iron core chute.
During operation, laminate base laminating place puts, laminating on base dropping place core cylinder and tiltedly carving, fix aft-loaded airfoil with fastening bolt and tiltedly carve, making tiltedly to carve cylindrical is pre-fixed core positioning straight footpath size; Subsequently, location taper key is put into taper groove, only need during lamination to stack segmental punching along the helicoidal structure outside the taper key of location on request, laminate, welded rear jackscrew and back down and tiltedly carve, tiltedly carve top Song Houneng to extract easily, depart from core cylinder, core cylinder vertically hangs out, location taper key is still stayed in skewed slot unshakable in one's determination and is removed, and easily pulls iron core and quality uppity problem when overcoming existing generator stator iron core laminating device tread flaking.
Reasonable in design of the present invention is reliable, in conjunction with the feature of flume structure stator core, laminating of flume structure stator core is realized by new construction, angle of bevel is ensured effectively, quality easily controls, and tread flaking is easy, not easily pull iron core, there is simple, the easy to operate and advantage that cost is low of structure.
