-0.045 + 0.066These stator muscle will withdraw from stator core from press-fit tire after finishing welding, usually it is machined, and the radius run-out degree of stator muscle after the Vehicle Processing and stator core requires smaller or equal to 0.05, and the regularity that requires stator slot shape and punching flute profile simultaneously is smaller or equal to 0.20.
But, because the existence of above-mentioned " secondary clamping " causes frame bore and the axiality that press-fits the tire external diameter to can not get guaranteeing.
Summary of the invention
The purpose of this utility model is the defective that can not get guaranteeing at " secondary clamping " in the prior art frame bore that causes and axiality that press-fits the tire external diameter, a kind of unit stator iron core pressing device is proposed, to realize guaranteeing frame bore and the axiality that press-fits the tire external diameter.
For achieving the above object, according to an aspect of the present utility model, provide a kind of unit stator iron core pressing device, comprised that the end, two ends is provided with the fixed axle of center positioning hole, the top of described fixed axle is provided with locking unit; Be fixed on several spoke iron on the described fixed axle.
Preferably, described locking unit is a nut, and the screw thread on the top by described fixed axle is fixedlyed connected with described fixed axle.
Preferably, described spoke iron periphery is fixed with the alloy panel.
Preferably, described center positioning hole is a C shape center positioning hole.
Preferably, be fixed with in the bottom of described fixed axle and press down frame, set up dismountable locating piece described pressing down.
Preferably, the unit stator iron core pressing device also comprises: be arranged on the upper pressed tyre below the locking unit, be arranged on described fixed axle bottom and press down the tire that presses down between the frame, fastening described upper pressed tyre and press down at least four fixed cells of tire and stator core.
Preferably, described fixed cell is a bolt.
Each embodiment of the utility model is by being provided with several spoke ferropexies on the fixed axle of center positioning hole in the end, two ends, feasible laminating to stator punching, the welding of stator muscle and finish turning stator core are once finished, the defective of having avoided " secondary clamping " the of the prior art frame bore that causes and axiality that press-fits the tire external diameter to can not get guaranteeing.。
Other features and advantages of the utility model will be set forth in the following description, and, partly from specification, become apparent, perhaps understand by implementing the utility model.The purpose of this utility model and other advantages can realize and obtain by specifically noted structure in the specification of being write, claims and accompanying drawing.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, and constitutes the part of specification, is used from explanation the utility model with embodiment one of the present utility model, does not constitute restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the axial cutaway view according to the utility model unit stator iron core pressing device embodiment;
Fig. 2 is the front view according to the utility model unit stator iron core pressing device embodiment.
In conjunction with the accompanying drawings, Reference numeral is as follows among the utility model embodiment: the fixed axle of 1-, 2-locking unit; 3-spoke iron; 4-presses down frame; The 5-locating piece; The 6-upper pressed tyre; 7-presses down tire.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.
According to the utility model embodiment, provide a kind of unit stator iron core pressing device.Fig. 1 and Fig. 2 are respectively axial cutaway view and the front view according to the utility model unit stator iron core pressing device embodiment.As depicted in figs. 1 and 2, present embodiment comprises: fixed axle 1, locking unit 2 and spoke iron 3, this fixed axle 1 can reflect that the size that is press fit into by the internal diameter of the stator punching of its press-loading apparatus of forming is a fixed value, end, fixed axle 1 two ends is provided with center positioning hole, and this center positioning hole can be C shape center positioning hole; Locking unit 2 is arranged on the top of fixed axle 1, and this locking unit 2 can be nut, and the screw thread on the top by fixed axle 1 is fixedlyed connected with fixed axle 1; Spoke iron 3 can radially and be axially fixed on the fixed axle 1, such as being fixed on the fixed axle 1 by welding or screw etc.
With prior art to press-fit tire different, the radical length of said stator iron core pressure mounting device promptly immobilizes, when press-fiting stator core, directly stator punching is enclosed within on this unit stator iron core pressing device and gets final product, press-fit fetal hair and give birth to the operating process of expanding and need not of the prior art making.Particularly, in order to increase the wearability of spoke iron 3, can be fixed with the alloy panel in spoke iron 3 peripheries.
After finishing the laminating of stator punching, promptly form stator core after, directly finish the welding operation of follow-up stator muscle, afterwards, will stator core not withdraw from the unit stator iron core pressing device, but directly the stator core after the welding be machined.
