The pressing clamp comprises a base, a pressing block and plug pins, wherein a base plate (6) and three positioning columns (2) are fixed on the base plate (5), and a pressing plate (1) is positioned on the positioning columns (2); three first horn holes (8) uniformly distributed by taking the center as the center of a circle are formed in the pressing plate (1), and three second horn holes (4) uniformly distributed by taking the center as the center of the circle are formed in the base plate (6); an angle is staggered between the first horn holes (8) and the corresponding second horn holes (4) by taking the center as the center of the circle; the plug pins (7) are inserted between the corresponding first horn holes (8) and second horn holes (4); and a pressing head (11) is arranged above the pressing plate (1). The pressing clamp has multiple functions in one object, and is an overlying rotor assembly clamp.

Description

Skew laminates rotor press-mounting fixture

Technical field

The present invention relates to one and laminate rotor press-mounting fixture, particularly relate to a kind of skew and laminate rotor press-mounting fixture modified node method; Belong to motor manufacturing frock.

Background technology

As everyone knows, laminated type rotor is made up of core assembly and armature spindle usually, and the lamination that core assembly is distributed with jet-bedding by some edges is overrided to form; At present, laminated mold is usually adopted to assemble core assembly.Existing skewed slot armature core laminated mold 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 present invention aims to provide that a kind of assembly precision is good, structure is simple, move back mould easily skew laminate rotor press-mounting fixture modified node method.

To achieve these goals, the present invention by the following technical solutions: it comprises base, briquetting and latch; Base is fixed with backing plate and three with this backing plate center for the uniform reference column in the center of circle, pressing plate is positioned on reference column; 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, and there is pressure head the top of pressing plate.

The angle staggered between first bellmouth orifice and the second corresponding bellmouth orifice is 15o8 '.

Compared with the prior art, the present invention is owing to have employed technique scheme, and with the center of base for circle fixes three reference columns, and the circle determined with three reference columns positions lamination for positioning datum; By reversing the latch between the first bellmouth orifice and the second corresponding bellmouth orifice being inserted in correspondence, the jet-bedding of each lamination is misplaced one by one simultaneously, thus spiral chute can be formed at the outer cylinder surface of rotor core assembly, there is the advantages such as easy to assembly, spiral chute skew angle is accurate.In addition, owing to being press-fitted in the endoporus of core assembly by pressure head by armature spindle, adopt a sleeve clamp not only can complete core assembly stack-press assembly, but also the assembling of core assembly and armature spindle can have been completed.The present invention has that structure is simple, assembly precision good, efficiency is high, move back the advantages such as mould is convenient.

In figure: pressing plate 1, reference column 2, lamination 3, second bellmouth orifice 4, base 5, backing plate 6, latch 7, first bellmouth orifice 8, drift 9, hydraulic press 10, pressure head 11, armature spindle 12.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described:

As shown in accompanying drawing 1 ~ 6, backing plate 6 is fixed on base 5, and backing plate 6 and base 5 have through hole; Base 5 is fixed with three with backing plate 6 center for the equally distributed reference column 2 in the center of circle, pressing plate 1 is positioned on reference column 2.Pressing plate 1 has with described center for up big and down small the first bellmouth orifice 8 of uniform three in the center of circle, backing plate 6 have with described center between up-small and down-big the second bellmouth orifice 4, first bellmouth orifice 8 of uniform three in the center of circle and the second corresponding bellmouth orifice 4 with described center for staggering clockwise or counterclockwise 15o8 ' in the center of circle; Latch 7 is inserted between the first corresponding bellmouth orifice 8 and the second bellmouth orifice 4, is matched in clearance between latch 7 and described two bellmouth orifices.

For the ease of armature spindle 12 can smoothly and core assembly be press-fitted, above pressing plate 1, have the drift 9 be connected with hydraulic press 10.When core assembly laminates after assembling completes, carry out shaping correction by drift 9 pairs of core assembly endoporus.

For the ease of being pressed in the endoporus of core assembly smoothly by armature spindle 12, above pressing plate 1, there is the pressure head 11 be connected with hydraulic press 10.

Operation principle: insert vertical respectively for three latches 7 in each second bellmouth orifice 4, the lamination 3 folded by code is enclosed within latch 7 by jet-bedding (not indicating in figure), and then is enclosed within latch 7 by the first bellmouth orifice 8 by pressing plate 1; With backing plate 6 center for edge, the center of circle is clockwise or rotate counterclockwise pressing plate 1, until three location holes (not indicating in figure) on pressing plate 1 are enclosed within reference column 2 respectively realize location; The upper end of three latches 7 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 core assembly; Then utilize hydraulic press 10, by pressing plate 1, each lamination 3 is laminated to required size (see Fig. 1, Fig. 2).Unclamp hydraulic press 10, drift 9 is arranged on hydraulic press 10, namely inserts in the endoporus of core assembly by drift 9, thus shaping and correction can be carried out to endoporus.Replace drift 9 with pressure head 11 armature spindle 12 to be pressed into and to form skew in the endoporus of core assembly and laminate rotor.

Adopt the present invention can realize laminating core assembly, core assembly endoporus shaping correction, core assembly and rotor and be press-fitted assembling three process, have that structure is simple, easy to operate, assembly precision is good, efficiency advantages of higher.
