Abstract
The utility model specifically provides a skewed slot stator iron core strain-free lamentation device, for solving problems of uncontrolled quality of a conventional stator iron core lamination device and an easily strained iron core during bodiless. The provided lamentation device comprises a lamination base, wherein cylindrical core cylinders are arranged on the lamination base; a plurality of vertically disposed conicity grooves are radially distributed on the outer periphery of each core cylinder; inclined wedges and positioning taper keys are arranged at intervals inside each conicity groove for clearance fit with the conicity groove; a jackscrew is screwed to the upper end surface of each inclined wedge, the bottom end of each jackscrew being in contact with the upper end surface of the respective core cylinder; fastening bolts fixed to the inclined wedges are screwed to the inner wall of the respective core cylinder; and the outer side of each positioning taper key is of a helical structure that cooperates with a stator iron core skewed slot. The characteristics of a skewed slot-structured stator iron core are combined into a new structure for the lamination of the skewed slot-structured stator iron core so that the skewed slot angle is effectively ensured, the quality of the provided lamination device may be easily controlled, bodiless is easier, and the iron core may not be easily strained. Therefore, the provided lamination device has the advantages of a simple structure, convenient operation and low cost.
Description
Technical field
The utility model relates to the electric machine stator iron stack-press device, and being specially a kind of skewed slot stator core does not have the stack-press device of pulling.
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 domestic production at present, because stator and rotor fluting and the non-centralized arrangement of winding, make magnetic potential of air gap contain harmonic wave in various degree, air-gap field is set up by magnetic potential, so just make that air-gap field is not to distribute according to sinusoidal rule fully, therefore the induced potential in the winding also not exclusively is sinusoidal wave, is namely also comprising a series of harmonic waves except sine-shaped first-harmonic.
The existence of harmonic wave will make the supplementary load loss of generator itself increase, decrease in efficiency, and temperature rise raises, and transmission line and near electric equipment are exerted an influence.
The flume structure stator core is harmonic carcellation effectively, reduces the supplementary load loss of generator itself, raises the efficiency, and reduces temperature rise, has become the following trend that improves the motor overall performance.
Practical, the technology of laminating is to satisfy the key that modern electrical machine is made efficiently.Good and bad labor productivity and the quality that directly influences electric machine iron core of stack-press device.Traditional stator core stack-press device comprises rise cartridge type stack-press device and fixing cartridge type stack-press device;
The cartridge type that rises stack-press device is to utilize 3 lobe formulas to rise by tube with punching internal diameter tensioner, locatees cylindrical unshakable in one's determination by taper key, realizes that skewed slot laminates.Its shortcoming is as follows: 1, perpendicularity unshakable in one's determination is relatively poor; 2, be only applicable to internal diameter less than the stator core of 1m, be not suitable for big-and-middle-sized stator core; 3, angle of bevel guarantees indirectly, and quality is wayward.
Fixedly the cartridge type stack-press device is to utilize axle location punching internal diameter, by movable taper key location core slots, realizes that skewed slot laminates.Its shortcoming is as follows: 1, tread flaking difficulty, pull iron core during tread flaking easily, particularly the iron core after the welding; 2, the uniform property of skewed slot is poor, and quality is wayward.
Present domestic skewed slot stator core stack-press device still is in exploration, conceptual phase, particularly is still blank for large and middle size motor flume structure stator core stack-press device.
Summary of the invention
Easily to pull iron core and the uppity problem of quality when the utility model has the tread flaking of stator core stack-press device now in order solving, to provide a kind of skewed slot stator core not have the stack-press device of pulling.
The utility model is to adopt following technical scheme to realize: the skewed slot stator core does not have the stack-press device of pulling, comprise and laminate base, laminate base and be provided with column core tube, radial equipartition has the tapering groove of some vertical settings on the outer circumference surface of core tube, be arranged at intervals with wedge and location taper key with its matched in clearance in the tapering groove, be screwed with the jackscrew that the lower end contacts with core tube upper surface on the upper surface of wedge, and core tube inwall is screwed with the fastening bolt fixing with wedge, and the outside of location taper key is the helicoidal structure that cooperates with stator iron core chute.
During operation, put and laminate base laminating the place, laminating fall a core tube and tiltedly carving of base, tiltedly carve with fastening bolt fixing back processing, making and tiltedly carving cylindrical is pre-fixed core location diameter dimension; Subsequently, to locate taper key and put into the tapering groove, only need during lamination to stack segmental punching along the helicoidal structure of locating the taper key outside on request, laminate, weld to back down tiltedly with jackscrew after finishing and carve, tiltedly carve top Song Houneng and extract easily, break away from the core tube, the core tube vertically hangs out, the location taper key is still stayed in the skewed slot unshakable in one's determination and is removed, and easily pulls iron core and the uppity problem of quality when having overcome existing stator core stack-press device tread flaking.
The utility model reasonable in design is reliable, characteristics in conjunction with the flume structure stator core, realize laminating of flume structure stator core by new construction, angle of bevel is guaranteed effectively, quality is controlled easily, and tread flaking is easy, is difficult for pulling iron core, has advantage simple in structure, easy to operate and that cost is low.
