Description

Composite stepper motor rotor core dislocation frock

Technical field

The utility model relates to a kind of composite stepper motor rotor core dislocation frock, belongs to motor frock technical field.

Background technology

At present, the composite stepper motor rotor is comprised of major parts such as rotor core, rotating shaft, magnet steel, the angle that must stagger between every adjacent rotor iron core on the rotor, and angular dimension is half of every adjacent two bottom angles on the rotor punching.And rotor only relies on naked eyes to be difficult to the precision of precise control in manufacture process, in case the angular error that staggers is larger, just having a strong impact on motor is in operation and exerts oneself, cause the decline of exerting oneself, the motor running noises is large, the generation of energy imbalance, even motor scraps, and reduced rate of finished products, improved production cost.

Summary of the invention

Technical problem to be solved in the utility model is the defective that overcomes prior art, provide a kind of simple in structure, easy to operate, in the less composite stepper motor rotor core of the rotor core angle time error that staggers dislocation frock.

In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of composite stepper motor rotor core dislocation frock, it comprises the rotor concave station, has the locating surface that matches with the rotor core periphery on the rotor concave station, be fitted with the first paired location plug-in unit and the second location plug-in unit on the rotor concave station, and the Central Symmetry face of the first location plug-in unit and the second location plug-in unit all is positioned at same plane with the axis of locating surface, the head end of the first location plug-in unit has the first insertion section that matches with inter-tooth slots profile of rotor core, and the first insertion section is symmetrical in the Central Symmetry face of the first location plug-in unit, the head end of the second location plug-in unit has two second insertion sections that inter-tooth slots profile match adjacent with rotor core, and the second insertion section is symmetrical in the Central Symmetry face of the second location plug-in unit.

After having adopted technique scheme, the structure of channel profiles between two adjacent teeth of rotor core of the structure of an inter-tooth slots profile of rotor core of the first insertion section and the second insertion section, when inserting the rotor core location, half of adjacent two bottom angles so that two adjacent rotor cores have staggered just in time, rotor core angle time error is smaller staggering, and ratio of precision is higher, and the utility model is simple in structure, easy to operate, improved production efficiency.
