Abstract
The utility model belongs to the motor production field and discloses a magnetic pole structure of a motor. The magnetic pole structure comprises a pull rod, overlaid cores and a left end plate and a right end plate which are arranged on the pull rod, wherein a punching hole is arranged in the center of each core, the pull rod penetrates through the punching holes and fixes the overlaid cores through the left and right end plates, and a magnetic pole fixing screw hole is processed on the outer sides of the overlaid cores. According to the magnetic pole structure, the problems of untight overlaying of the magnetic pole cores and loose fixation of the magnetic pole can be solved, and influence on normal operation of the motor by damage of machine winding due to friction of a rotor and a stator is avoided.
Description
Technical field
The utility model field of motor manufacturing, particularly a kind of motor pole structure.
Background technology
At present, existing direct current machine magnetic pole is a lamination, is with rivet stacked punching to be riveted together, and processes the screw thread that is used for fixing magnetic pole then in the side.If improper at pole lamination pressure in lamination process, rivet is not fastening, will cause the loosening screwed hole size that causes of pole lamination to become big during thread mill drilling.Like this, when the assembling magnetic pole, can cause magnetic pole fixing not tight, magnetic pole is loosening can to cause motor to sweep hall, damages motor windings, influences the normal operation of motor.
Summary of the invention
The purpose of the utility model is to provide a kind of motor pole structure, can solve that pole lamination is folded not to press tightly and the fixing loosening problem of magnetic pole, avoids motor to sweep that thorax damages motor windings and the normal operation that influences motor.
In order to achieve the above object, the utility model adopts following technical scheme to be achieved.
A kind of motor pole structure is characterized in that, comprises pull bar, and stacked punching is arranged on first member plate and right end plate on the pull bar; The center of said punching is provided with punching, and pull bar runs through said punching and fixes said stacked punching through said left and right end plate; The lateral surface of said stacked punching is processed with the magnetic pole fixing threaded hole.
The characteristics of technique scheme are with further improving:
Said magnetic pole fixing threaded hole extension is worked on the pull bar.
Said first member plate and right end plate are welded to connect with pull bar respectively.
The limit portion of said punching is provided with the grooved breach, and said stacked punching is processed with weld seam along the grooved breach.
In the motor pole structure of the utility model; The center of punching is provided with punching; Pull bar runs through punching and through the fixing stacked punching of left and right end plate, at the lateral surface processing magnetic pole fixing threaded hole of stacked punching, the extension of magnetic pole fixing threaded hole is worked on the pull bar then.The said fixing mode makes stacked punching more fastening on the one hand, and the extension of magnetic pole fixing threaded hole is worked on the pull bar on the other hand, even stacked punching is loosening, also can not influence the fixing of magnetic pole.In addition, the limit portion of punching is provided with the grooved breach, and stacked punching is processed with weld seam along the grooved breach, can be so that stacked punching is more fastening.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is explained further details.
Fig. 1 is the enlarged diagram of the punching structure of the utility model;
Fig. 2 is the partial schematic sectional view of a kind of motor pole structure of the utility model;
Among the figure: 1, punching; 2, punching; 3, grooved breach; 4, pull bar; 5, first member plate; 6, right end plate; 7, weld seam; 8, magnetic pole fixing threaded hole.
Embodiment
With reference to Fig. 1, the center of punching 1 is provided with the punching 2 of rectangle, and two edge portion of punching 1 are provided with two grooved breach 3 respectively, always have four grooved breach 3.Fig. 2 is a kind of motor pole structure of the utility model, and wherein, the cross section of pull bar 4 is a rectangle, runs through punching 2 and fixes stacked punchings through left and right end plate 5,6.Be specially: earlier first member plate 5 is welded on an end of pull bar 4, punching 1 stacked and compress after, welding right end plate 6; Then, in stacked punching, be processed with weld seam 7 along grooved breach 3; At last, in the lateral surface machining of stacked punching magnetic pole fixing threaded hole 8 is arranged, magnetic pole fixing threaded hole 8 extends and is worked on the pull bar 4.Said structure has solved that pole lamination is folded not to press tightly and the fixing loosening problem of magnetic pole, avoids motor to sweep that thorax damages motor windings and the normal operation that influences motor.
Although more than combine accompanying drawing that the embodiment of the utility model is described, the utility model is not limited to above-mentioned specific embodiments and applications field, and above-mentioned specific embodiments only is schematic, guiding, rather than restrictive.Those of ordinary skill in the art under the situation that does not break away from the scope that the utility model claim protected, can also make a variety of forms under the enlightenment of this specification, these all belong to the row of the utility model protection.
