Abstract
The utility model discloses a kind of stator laminating tool can measuring skewed slot size, the stator comprising external diameter cylindrical shape consistent with punching internal diameter laminates tire, the cylindrical lower end that stator laminates tire is connected in the middle of the inner circle of lower pressure ring of a ring-type, and an inner bushing ring is connected to the junction that stator laminates tire and lower pressure ring; Stator laminates on tire and has a straight trough and a skewed slot; A taper key is arranged at stator and laminates in the skewed slot of tire, and the skewed slot laminating tire with stator is interference fits, and has the angle consistent with skewed stator core slot; A straight key is arranged at stator and laminates in the straight trough of tire, and the straight trough laminating tire with stator is matched in clearance, and middle part has a boss equal with punching well width.The utility model structure is simple, is easy to operation, can measures the offset distance of stator at axial length fast and accurately, thus the reasonability of checking Fixture Design; When mass simultaneous is produced, the beasurement base that can check as node.
Description
Technical field
The utility model relates to a kind of stator laminating tool can measuring skewed slot size, is suitable for laminating and the measurement of angle of bevel of medium-and-large-sized skewed stator slot motor.
Background technology
For eliminating cogging torque harmonic wave, medium-and-large-sized motor stator majority is skewed slot.Punching tiltedly and foldedly tiltedly can realize skewed slot, the former laminate after skewed slot precision higher, but its manufacturing cost and manufacturability and production efficiency are all not as good as tiltedly folded.Therefore for the motor of skewed slot, most stator is manufactured producer and is all selected tiltedly folded.
Tiltedly laminating technique is all ensure angle of bevel by frock, after laminating, determines because positioning datum is bad, no matter be that the skewed slot of angle of bevel or tooth center line is apart from being all difficult to Measurement accuracy.This design examination for frock, process design review, procedure inspection and quality tracing all will cause difficulty.The measurement of stator core oblique poststack skewed slot is very important, is related to the overall performance of product.
Utility model content
Fold the problem of rake angle measurement to solve current stator, applicant, through Improvement, provides a kind of stator laminating tool can measuring skewed slot size.
The technical solution of the utility model is as follows:
A kind of stator laminating tool can measuring skewed slot size, the stator comprising external diameter cylindrical shape consistent with punching internal diameter laminates tire, the cylindrical lower end that described stator laminates tire is vertically connected in the middle of the inner circle of lower pressure ring of a ring-type, and an inner bushing ring is connected to the junction that described stator laminates tire and lower pressure ring; Described stator laminates on tire and has a straight trough and a skewed slot; A taper key is arranged at described stator and laminates in the skewed slot of tire, and the skewed slot laminating tire with described stator is interference fits, and described taper key has the angle of inclination consistent with skewed stator core slot; A straight key is arranged at described stator and laminates in the straight trough of tire, and the straight trough laminating tire with described stator is matched in clearance, and the middle part of described straight key has a boss equal with punching well width.
Advantageous Effects of the present utility model is:
The utility model laminates on tire at stator and opens a groove more, processes a straight key simultaneously, and structure is simple, is easy to operation.Utilize the positioning action of positioning key, the offset distance of stator at axial length can be measured fast and accurately, thus the reasonability of checking Fixture Design; When mass simultaneous is produced, the beasurement base that can check as node.
Advantage of the present utility model provides in the description of embodiment part below, and part will become obvious from the following description, or be recognized by practice of the present utility model.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of positioning key.
Fig. 3 is the location diagram of positioning key lower end and punching.
Fig. 4 is the location diagram of positioning key upper end and punching.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Figure 1, each modular construction of stator laminating tool of the present utility model and effect as follows:
Lower pressure ring 1, for having the ring-type of one fixed width, the external diameter that its internal diameter and stator laminate tire 4 is consistent, support stator trim ring during for laminating.
Inner bushing ring 2, be ring-type, the external diameter that its internal diameter and stator laminate tire 4 is consistent, ensures the axiality of stator pressing ring and stator core during for laminating.
Positioning key 3, is straight key, has a boss in the middle part of it, and the width of lower end boss is equal with punching groove width; Positioning key 3 and the stator straight trough grooved laminated on tire 4 are matched in clearance, can move freely in width of keyway direction, embed in punching groove to facilitate.
Stator laminates tire 4, and its external diameter is consistent with punching internal diameter, to ensure the uniformity of air gap; Stator laminates on tire 4 and has two keyways simultaneously, is respectively a straight trough and a skewed slot.
Taper key 5, its angle is consistent with the angle of skewed stator core slot, and itself and the stator skewed slot grooved laminated on tire 4 is interference fits.
The utility model, when installing and using, is first thrown taper key 5 into stator and is laminated tire 4.When laminating, first lower pressure ring 1 and inner bushing ring 2 are placed on hydraulic press, then stator are laminated tire 4 and be placed in the middle of lower pressure ring 1 and inner bushing ring 2; Then laminate at stator in the straight trough of tire 4 and insert positioning key 3; Next stator pressing ring and bottom punching is placed according to the location of taper key 5, and make the lower end boss of positioning key 3 be stuck in bottom punching groove, using this groove as baseline trough, the lower end datum mark of this baseline trough is (as shown in Figure 3) of aliging with an edge of boss; Then place each punching successively to carry out laminating operation.After having laminated, the edge, boss upper end utilizing positioning key 3 is benchmark, measures the distance of the upper end datum mark of itself and baseline trough, to verify the dimensional accuracy (as shown in Figure 4) of skewed stator slot.
Above-described is only preferred implementation of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate under the prerequisite not departing from basic conception of the present utility model, all should think and be included within protection range of the present utility model.
