Description
Technical field
The present invention relates to a kind of laminating stator pressing clamp, particularly relate to a kind of skew laminating stator iron core assembly fixture; Belong to motor manufacturing frock.
Background technology
As everyone knows, be for magnetic steel built-in type magneto for medium and small permanent magnet synchronous motor ， Te Do, the most frequently used method adopts skewed stator slot structure to weaken slot effect, the usual mode adopting hand assembled to laminate is to form skewed stator slot at present, there is labour intensity large, efficiency is low, the defects such as skewed slot windup-degree inaccuracy, for this reason, notification number is " CN103259378A ", the utility model patent that name is called " chute stator is unshakable in one's determination without pulling stack-press device " discloses a kind of skew laminating stator iron core pressing clamp, it is by the core cylinder be fixed on base, vertically be opened in the some taper groove on this core drum outer wall, be fixed on the positioning key in each taper groove, the bolt connecting base and pressing plate is formed, who is so fairly simple for this patent, but still belong to manual, labour intensity is large, complex operation, efficiency is low.
Summary of the invention
For the above-mentioned defect existed in prior art, the present invention aims to provide the skew laminating stator iron core multipurpose assembling jig that a kind of assembly precision is good, structure is simple, easy to operate, efficiency is high.
To achieve these goals, the present invention by the following technical solutions: it comprises stepped positioning core axle, the pressing plate suitable with this mandrel; Pressing plate is located on positioning core axle by cloudy seam, pressing plate to have with positioning core axle axis for equally distributed three up big and down small the first bellmouth orifices in the center of circle, positioning core axle has with described axis for equally distributed three up-small and down-big the second bellmouth orifices in the center of circle; Between first bellmouth orifice and the second corresponding bellmouth orifice with described axis for staggering an angle in the center of circle, latch is inserted between the first corresponding bellmouth orifice and the second bellmouth orifice.
Pressing plate has endoporus, and there is the stud protruded upward through this endoporus on the top of positioning core axle, and this stud has nut; Described stud is fixed with spacer pin, in the endoporus of pressing plate, has the stopper slot suitable with this spacer pin; Positioning core axle is seated in head part ring.
Compared with the prior art, the present invention is owing to have employed technique scheme, with positioning core axle, workpiece (stator lamination) endoporus is positioned, by reversing the latch between the first bellmouth orifice and the second corresponding bellmouth orifice being inserted in correspondence, the jet-bedding of each stator lamination is misplaced one by one, thus form spiral chute at the inner periphery of stator core assemblies; Have easy to assembly, spiral chute skew angle accurately, efficiency advantages of higher.In addition, owing to laminating rear each stator lamination by platen clamp, therefore each stator lamination can be taken off together with positioning core axle from press and delivers to milling machine and process welding groove, then when the not demoulding, each stator lamination be welded as a whole and form stator core assemblies, finally utilizing head part ring to carry out the demoulding; Therefore adopt that clamped one time of the present invention can complete that lamination skew laminates, lamination groove milling, lamination welding and the demoulding etc. are many to manufacturing procedure, expanded the scope of application that stator core laminates fixture.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described.
As shown in accompanying drawing 1 ~ 6, pressing plate 1 is located on stepped positioning core axle 3 by cloudy seam, pressing plate 1 to have with positioning core axle 3 axis for equally distributed three up big and down small the first bellmouth orifices 7 in the center of circle, positioning core axle 3 has with described axis for equally distributed three up-small and down-big the second bellmouth orifices 5 in the center of circle; Between first bellmouth orifice 7 and the second corresponding bellmouth orifice 5 with described axis for staggering an angle in the center of circle, latch 6 is inserted between the first corresponding bellmouth orifice 7 and the second bellmouth orifice 5.Latch 6 and the second bellmouth orifice 5, first bellmouth orifice 7 are matched in clearance.
For the ease of the stator lamination 2 after laminating is clamped, the middle position of pressing plate 1 offers endoporus (not indicating in figure), the top of positioning core axle 3 has and is connected as a single entity with it and passes the stud (not indicating in figure) that this endoporus protrudes upward, and this stud has nut (not indicating in figure); Pressing plate 1 can be stepped up on positioning core axle 3 by this nut.
In order to ensure that angle of bevel is accurate, described stud being fixed with spacer pin 8, in the endoporus of pressing plate 1, having the stopper slot 9 suitable with this spacer pin.
For the ease of can the demoulding smoothly after welding, positioning core axle 3 be seated in head part ring 4.
During use, insert vertical respectively for three latches 6 in each second bellmouth orifice 5, the stator lamination 2 folded by code is enclosed within latch 6 by jet-bedding (not indicating in figure), and then is enclosed within latch 6 by the first bellmouth orifice 7 by pressing plate 1; With the axis of positioning core axle 3 for edge, the center of circle is clockwise or rotate counterclockwise pressing plate 1, until spacer pin 8 to snap in stopper slot 9 (in the process, the upper end of three latches 6 can be reversed around described axis, thus the jet-bedding realizing each stator lamination 2 misplaces one by one and forms spiral chute at the inner periphery of core assembly), then utilize hydraulic press pressure head (not shown) to press to preliminary dimension.
After having laminated, the pressure head of hydraulic press rises, and is clamped by pressing plate 1, then taken off from hydraulic press by positioning core axle 3 and deliver to milling machine, mill out four welding grooves 10 at each stator lamination 2 outer round surface with nut.
After milling completes, the positioning core axle 3 being clamped with stator lamination 2 is taken off from milling machine, each stator lamination 2 welding is connected as a single entity and forms stator core assemblies.
Taken off from stud by nut, be seated by mandrel in head part ring 4, beaing stud can exit positioning core axle 3 from the endoporus of stator core assemblies.
