Abstract
This invention discloses a pressing device of a stator iron core with six split floating pressure heads having the advantage of adjusting the pressure separately in the process of pressing including a working stand with a location post on it, stator core lamination jacketing the post, a hydraulic pressure control device is set on top of the post and connected with the head, which is composed of multiple floating sub-heads uniformly distributed in circle connected with their relative hydraulic control devices and a locating device is set on the head of the sub-head.
Description
Technical field
The present invention relates to a kind of press-loading device of generator stator core, relate in particular to a kind of unit stator iron core pressing equipment that has the floating type pressure head of six splits.
Background technology
The traditional integral type pressure head of the many employings of generation current machine stator iron core pressure mounting, because the silicon steel sheet gauge itself has error, add the influence of smear film thickness, therefore in the stator-core lamination process, there is accumulated error, the difference in height that occurs silicon steel sheet yoke portion and tooth portion sometimes, or " waveform " difference in height appears on same horizontal plane.If adopt the integral type pressure head, can not accurately judge for local becoming flexible unshakable in one's determination, can not effectively compensate, the unbalanced problem of iron core pressure mounting coefficient occurs, thereby caused stator in use fragile, shorten its useful life.
Summary of the invention
Purpose of the present invention is exactly to adopt the integral type pressure head when existing generator unit stator press-fits in order to solve, cause the intimate problems such as coefficient is inhomogeneous of press-fiting, provide a kind of have simple in structure, easy to use, in press-fiting process, can adjust pressure respectively, carry out the unit stator iron core pressing equipment that has the floating type pressure head of six splits of targeted lamination compensation.
The present invention has adopted following technical scheme for achieving the above object:
A kind of unit stator iron core pressing equipment that has the floating type pressure head of six splits, press-loading device has workbench, workbench is provided with reference column, at reference column suit stator-core lamination, top at reference column is provided with hydraulic control device, and hydraulic control device is connected with pressure head, and described pressure head is made up of a plurality of floating type minute pressure heads by circumference uniform distribution, floating type minute pressure head is connected with corresponding hydraulic control device separately, also is provided with positioner at floating type minute on the pressure head.
Pressure head had six in described floating type minute, and itself and core lamination contact-making surface are cambered surface.
Described hydraulic control device is a hydraulic cylinder, on floating type split head the cylinder pressure that cooperates with hydraulic cylinder is arranged.
Described positioner is the scale that is installed on each floating type minute pressure head.
The present invention changes existing integral type into six splits floating type pressure head, can effectively adjust core lamination at pressure axial and radially, simultaneously because six floating type pressure heads are uniform along full circle unshakable in one's determination, therefore also can adjust pressure effectively for whole core lamination horizontal plane, carry out targeted lamination compensation then, solved the unbalanced problem of iron core pressure mounting coefficient that adopts traditional integral type pressure head to occur.
The invention has the beneficial effects as follows: rational in infrastructure, easy to use, press-fit effective, the rate of finished products height of product.

Fig. 1 is the structural representation of existing unit stator iron core pressing equipment;
Fig. 2 is a nail of the present invention press-loading device structural representation unshakable in one's determination;
Fig. 3 is the vertical view of pressure head of the present invention.
Wherein, 1. workbench, 2. reference column, 3. core lamination, 4. hydraulic control device, 5. floating type minute pressure head, 6. scale.
Embodiment
The invention will be further described below in conjunction with accompanying drawing and embodiment.
Fig. 1 is existing unit stator iron core pressing equipment structure chart, and it has adopted the integral type pressure head, easily causes the unbalanced problem of iron core pressure mounting coefficient, influences the quality and the life-span of product.
Fig. 2 has provided configuration diagram of the present invention, on workbench 1, be provided with reference column 2, suit core lamination 3 on it, at the top of reference column 2 are hydraulic control devices 4, i.e. hydraulic cylinder, six pressure heads of having formed equipment along floating type minute uniform pressure head 5 of periphery, each floating type minute pressure head 5 is equipped with cylinder pressure and is connected with corresponding hydraulic control device 4 separately, floating type minute pressure head 5 adopts cambered surface with the contact-making surface of core lamination 3, also is provided with scale 6 at floating type minute on the pressure head 5 simultaneously, in order to the location.
In the present invention, the quantity of pressure head is not limited to six, as long as have more than two.A plurality of by pressure head is become by existing one, in what position deviation is arranged in the time of in pressing process, can finding unshakable in one's determination compacting easily, the deviation position is mended into video disc unshakable in one's determination get final product then, thereby guaranteed the q﹠r of product.
