Abstract
The invention relates to a clamp for a rotor mechanical torsion chute, which consists of an axial compression upper die, chute needles, struts and a riveting head. A backing plate seat is arranged on a presser foot and is fixed on the presser foot through bolts; a pedestal is arranged on the backing plate seat and is fixed on the backing plate seat by the bolts; the center of the pedestal is provided with the riveting head, the surface of the pedestal at the outside of the outer circle of the riveting head is provided with two symmetrical chute needles; ejector rods are distributed on the surface of the pedestal uniformly; and the axial compression upper die is arranged above the pedestal, and the periphery of the axial compression upper die is distributed with the struts uniformly. The clamp ensures the consistency of a chute ratio; after performing the axial compression, a rotor is subjected to die casting directly, so that the clamp saves working procedures of artificially assembling an imitated shaft and screwing in and screwing off nuts, reduces operators and improves the quality of products and productivity.
Description
Technical field: the present invention relates to a kind of clamp for rotor mechanical torsion chute.
Background technology: in the household electrical appliance industry, using a large amount of permanent-split capacitor motors.When producing this type motor, generally there is the stator of contacting directly all to take much count of, and all be equipped with means of testing usually for secure context, insulation resistance for example, turn-to-turn is withstand voltage, and is withstand voltage over the ground etc., more directly perceived because of it, just can directly judge with checkout equipment.And for the closely-related rotor of electromechanics performance, because of most of producers do not possess the rotor quality somascope, by the time problem has appearred in the finished product motor test, and determining is rotor when causing, and has cast the certain economic loss.Method can only be " standard " rotor replacement method the most intuitively.See from the practice of quality analysis, cause the electrical micro-machine performance to fluctuate widely even underproof reason, we can say that rotor quality will account for about 80%, therefore must not adopt a casual attitude the quality of rotor.
In asynchronous machine, have additional torque, this additional torque be by high order harmonic component to due to the effect of rotor, so the size of additional torque must just take in and control in the design of electrical motor stage.Reducing the very effective method of additional torque is rotor chute, and rotor chute also is one of method that reduces noise, and a certain proportion of stator slot distance of oblique mistake can make motor avoid radial vibration, but it is limited that transverse vibration is reduced.Therefore rotor chute is to the additional torque of motor, and noise vibrates, and supplementary load loss have tangible influence.
Artificial rotor torsion chute is often adopted in traditional production, with the rotor pack of some, realizes centralized positioning by dummy shaft and the cylinder more bigger than punching external diameter, and with the oblique mistake of punching, the nut of screwing on then is to tightly taking out by the groove lining bar of reserving gradient.When the artificial rotor torsion chute of this groove lining bar form is used for electrical micro-machine,, often to be out of shape even decrease disconnected because the groove lining bar is thin.Because of manual operation, different people's different time, operation always has difference, and is influential to the motor product quality.After the die casting simultaneously, need again pine to go nut to remove dummy shaft, inefficiency.
Summary of the invention: the object of the invention will provide a kind of clamp for rotor mechanical torsion chute exactly, turns round groove to manual work and changes the mechanical type torsion chute into.The objective of the invention is to realize like this, a kind of clamp for rotor mechanical torsion chute is made up of last item patrix, skewed slot pin, depression bar, die, and it is characterized in that: presser feet is provided with the backing plate seat, and by being bolted on the presser feet; Described backing plate seat is provided with base, and by being bolted on the backing plate seat; Central authorities at base are provided with die, and the cylindrical outside susceptor surface of die is provided with the skewed slot pin of two symmetries, also is evenly equipped with ejector beam on the surface of base; Above described base, be provided with the last item patrix, be evenly equipped with depression bar around the last item patrix.The present invention has guaranteed the consistency of skewed slot ratio, can directly carry out motor rotor die-casting behind the last item rotor, has saved artificially to go up the operation of dummy shaft and tight, loose nut and can reduce operating personnel.Improve product quality, improved productivity ratio.

Fig. 4 is the rotor sheet sketch map;
1. presser feet, 2. bolt, 3. backing plate seat, 4. base, 5. die, 6. skewed slot pin, 7. ejector beam, 8. last item patrix, 9. depression bar, 10. ventilation hole, 11. rotor, 12. rotor sheets.
Embodiment: the present invention is described further below in conjunction with accompanying drawing:
In the drawings, a kind of clamp for rotor mechanical torsion chute is made up of last item patrix 8, skewed slot pin 6, depression bar 9,5 of dies, and it is characterized in that: presser feet 1 is provided with backing plate seat 3, and is fixed on the presser feet 1 by bolt 2; Described backing plate seat 3 is provided with base 4, and is fixed on the backing plate seat 3 by bolt 2; Central authorities at base 4 are provided with die 5, and base 4 surfaces, cylindrical outside of die 5 are provided with the skewed slot pin 6 of two symmetries, also are evenly equipped with ejector beam 7 on the surface of base 4; Above described base 4, be provided with last item patrix 8, be evenly equipped with depression bar 9 around the last item patrix 8.During practical implementation; Rotor pack with some; From the little ventilation hole that penetrates rotor sheet of skewed slot needle section, play the Primary Location effect, then machine shaft is inserted in the rotor sheet central shaft hole, when the last item patrix is descending; Rotor sheet is when slip compresses downwards, and the skewed slot pin rotates to the skewed slot ratio that needs with it.When the last item patrix came downwards to bottom dead centre, the last item size put in place, and machine shaft and rotor sheet are riveted tightly, and skewed slot is than fixing.Different according to skewed slot pin angle of inclination, the different size rotor has different rotor skewed slot ratio.But the same size rotor chute has been guaranteed the consistency of skewed slot ratio than being accomplished by equipment, can directly carry out motor rotor die-casting behind the last item rotor, and machine shaft is dummy shaft during die casting, need not upper and lower dummy shaft and tight, loose nut operation.Product quality and economic benefit have been improved.
