Description
Technical field
The utility model relates to a kind of laminated type rotor core component assembling clamps, particularly relates to a kind of skew and laminates rotor core component assembling clamps; Belong to motor manufacturing frock.
Background technology
As everyone knows, core assembly forms the parts of DC motor rotor, and the lamination being usually distributed with some jet-beddings by edge is overrided to form; At present, laminated mold is usually adopted to assemble core assembly.Existing chute armature core stacked die is generally made up of closed assembly mandrel, upper lower bolster, locking nut, positioning key, pressure head etc.Notification number is " CN203014613U ", name is called " hidden pole type chute rotor iron core overlapping mold tool ", and " CN202190188U ", name are called that " chute rotor iron core overlapping mold with spherical keys " individually discloses the assembling device that two kinds laminate chute rotor iron core assembly, there is complex structure, move back the defects such as mould trouble, complex operation.
Summary of the invention
For the above-mentioned defect existed in prior art, the utility model aims to provide that a kind of assembly precision is high, structure is simple, move back mould easily skew laminate rotor core component assembling fixture.
To achieve these goals, the utility model by the following technical solutions: it comprises base, briquetting, mandrel and latch; Base is fixed with backing plate and three with this backing plate center for the uniform locating dowel in the center of circle, pressing plate is positioned in locating dowel; Pressing plate has with described center for up big and down small the first bellmouth orifice of uniform three in the center of circle, backing plate having with described center for up-small and down-big the second bellmouth orifice of uniform three in the center of circle, between first bellmouth orifice and the second corresponding bellmouth orifice with described center for staggering an angle in the center of circle, latch is inserted between the first corresponding bellmouth orifice and the second bellmouth orifice; Mandrel protrudes upward through base, backing plate and pressing plate, and packing ring is fixed on mandrel by nut.
The angle staggered between first bellmouth orifice and the second corresponding bellmouth orifice is 12o18 '; There is centre bore at the two ends of mandrel.
Compared with the prior art, the utility model is owing to have employed technique scheme, and with the center of base for circle fixes three locating dowels, and the circle determined with three locating dowels positions lamination for positioning datum; The jet-bedding of each lamination is misplaced one by one by being inserted in latch between the first corresponding bellmouth orifice and the second corresponding bellmouth orifice and forming spiral chute at the outer cylinder surface of rotor core assembly simultaneously, therefore there is the advantages such as easy to assembly, spiral chute skew angle is accurate.In addition, owing to have employed dismountable mandrel, it is convenient and swift therefore to move back mould.3rd, mandrel also can be utilized after moving back mould to clamp core assembly, and make short-circuited conducting sleeve be embedded in the copper sheathing banding in jet-bedding with roll riveting; There is the function of one-object-many-purposes.4th, only mandrel need be removed and can be carried out soldering, therefore can not take or damage frock because of high temperature brazing.

Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
As shown in accompanying drawing 1 ~ 7, backing plate 7 is fixed on base 6, and backing plate 7 and base 6 have through hole; Base 6 is fixed with three with backing plate 7 center for the equally distributed locating dowel 2 in the center of circle, pressing plate 1 is positioned in locating dowel 2.Pressing plate 1 has with described center for up big and down small the first bellmouth orifice 9 of uniform three in the center of circle, backing plate 7 have with described center between up-small and down-big the second bellmouth orifice 5, first bellmouth orifice 9 of uniform three in the center of circle and the second corresponding bellmouth orifice 5 with described center for staggering clockwise or counterclockwise 12o18 ' in the center of circle; Latch 8 is inserted between the first corresponding bellmouth orifice 9 and the second bellmouth orifice 5, is matched in clearance between latch 8 and described two bellmouth orifices.Mandrel 4 is through passing through from protruding upward on base 6, backing plate 7 and pressing plate 1, and packing ring 11 is fixed on mandrel 4 by nut 10.
For the ease of making short-circuited conducting sleeve 13 be inserted in by the mode of roll riveting to laminate copper bar 12 banding in core assembly skewed slot, the two ends of mandrel 4 are provided with centre bore.
Operation principle: insert vertical respectively for three latches 8 in each second bellmouth orifice 5, the lamination 3 folded by code is enclosed within latch 8 by jet-bedding (not indicating in figure), and then is enclosed within latch 8 by the first bellmouth orifice 9 by pressing plate 1; With backing plate 7 center for edge, the center of circle is clockwise or rotate counterclockwise pressing plate 1, until three locating holes (not indicating in figure) on pressing plate 1 are enclosed within locating dowel 2 respectively realize location; So the upper end of three latches 8 can be reversed around described center; Thus the jet-bedding realizing each lamination 3 misplaces one by one and forms spiral chute at the outer cylinder surface of rotor core assembly; Then utilize the pressure head of hydraulic press, by pressing plate 1, each lamination 3 is laminated to required size (see Fig. 4).Unclamp hydraulic press pressure head, by mandrel 4 from bottom to top through the through hole of base 6, backing plate 7, each lamination 3, pressing plate 1, then by nut 10 and packing ring 11, each lamination 3 is fixedly clamped, unloads lower platen 1, the lamination 3 laminated is taken out together with mandrel 4 from base 6.Clamp mandrel 4 with vice 14, copper bar 12 is inserted one by one in each skewed slot (not indicating in figure), bind round the two ends (see Fig. 5) at copper bar 12 respectively with short-circuited conducting sleeve 13; Unclamp vice 14, with the centre bore at mandrel 4 two ends location, utilize the knurled wheel 15 be arranged on lathe saddle that (see Fig. 6) is riveted tightly in two short-circuited conducting sleeve 13 roll extrusion; Then unclamp nut 10, extraction mandrel 4 can carry out soldering by rotor core assembly feeding vacuum brazing furnace.
The utility model not only can be used as rotor slot skew laminated mold and has used, but also can inlay furniture as copper bar and use, and can also use as the roll extrusion rivet clasp fixture of copper bar and short-circuited conducting sleeve.
