Abstract
The invention discloses an expander. The expander comprises a shaft, wherein expander cores are sleeved on the two ends of the shaft; an expander sleeve is sleeved outside the expander core; and the expander cores on the two ends of the shaft and the expander sleeve are centrosymmetric with respect to the shaft. The expander provided by the invention can once press and fit a motor stator with a long iron core, and can ensure the coaxiality and co-precision of seam allowances on the two ends of the motor stator, so that the production quality is improved.
Description
Technical field
The present invention relates to a kind of expander, refer more particularly to a kind of expander for motor stator core inner ring location.
Background technology
Motor stator core is one of important component of motor, the quality of its quality directly affects the quality of overall performance, expander is now generally used to press-fit iron core inner circle, its cylindricity is made to reach certain standard, but run into the situation that core length is longer, just repeatedly to press-fit it, so just can not ensure the axiality of motor stator two ends seam, thus affect the quality of motor.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of expander that disposablely can press-fit the longer motor stator of iron core.
In order to solve the problems of the technologies described above, the invention provides a kind of expander, comprising axle, axle two ends cover has the core that rises, and the core outer race that rises has ringfeder, and what axle two ends were provided with rise core and ringfeder are about axle Central Symmetry.
Adopt said structure, its beneficial effect is: expander of the present invention is provided with identical rise core and ringfeder at the two ends of its axle, for the motor stator that core length is longer, and can synchronous press mounting motor stator two ends seam, thus ensure that the axle degree of two ends seam is identical, ensure that the quality of motor stator.
Accompanying drawing explanation
Fig. 1 is the structural representation of expander of the present invention.
In figure: 1-axle, 2-rises core, 3-ringfeder.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
As shown in Figure 1, a kind of expander, comprises axle 1, and axle 1 two ends cover has the core 2 that rises, and core 2 outer race that rises has ringfeder 3, and what axle 1 two ends were provided with rise core 2 and ringfeder 3 are about axle Central Symmetry.
In actual production, common expander can only be applicable to press-fit the shorter motor stator of core dimensions, for longer dimension, substep is needed to press-fit, the effect of secondary press-fitting can not be identical, so cause the axle degree of motor stator two ends seam not identical, thus affects the quality of motor.
Expander of the present invention solves above-mentioned technical problem, motor stator is enclosed within expander, make the ringfeder 3 at expander two ends corresponding with the two ends seam of motor stator, because two parts core 2 that rises is identical with ringfeder 3, when press-fiting, identical to motor stator two ends seam applied pressure, generation to press-fit effect identical, so ensure that two ends seam axiality, same to precision.
