Description
Technical field
The utility model relates to electro spindle technical field, particularly relates to a kind of electro spindle rotor assembly structure.
Background technology
As far back as the 1950's, just occurred the high-frequency motor spindle for grinding aperture, the radio tube that frequency converter at that time adopts, although rotating speed is high, the power transmitted is little, and torque is also little.Along with the development of computer technology of the needs of high-speed cutting development and power electronic device, microelectronic component creates frequency converter and the vector control driver of all solid state original paper; Adding the appearance of admixture ceramics bearing, there is high-power, the large torque of processing for milling, drilling, machining center etc., high-revolving electro spindle at late 1980s, the beginning of the nineties in what make.And these electro spindle are all interference fit in the connection of rotor and axle, be generally hot charging or cold pressing, so not only very loaded down with trivial details at processing technology, fit on, need more equipment, and the more important thing is when being necessary dismounting rotor, cavity between rotor and axle can only be squeezed into hydraulic oil, rotor is extruded, or can only destructive rotor be pulled down.So not only waste time and energy, improve maintenance cost, and also bring pollution to a certain degree to environment.
Summary of the invention
Have that maintenance difficult, operation are various, the more high defect of maintenance cost to overcome existing electro spindle rotor fit on, the utility model provides a kind of electro spindle rotor assembly structure (combined), make electro spindle rotor assembly process simple, stable and reliable operation, safeguards more simple and convenient.
Described electro spindle rotor assembly structure (combined), comprise axle, front end housing, support, common A type key, rotor bushing, stator core, rotor, Z1 type expansion set, expansion set gland, rear end cap, described support and described front end housing, described rear end cap form a cavity, described axle passes the center of described rear end cap and described front end housing, described rotor hot charging on described rotor bushing, and is contained in the middle part of described axle, and described iron core stator is colded pressing at described inboard wall of base.
Further, described rotor is cast-aluminum rotor.
Further, described iron core stator is the iron core stator with winding.
Further, described support is provided with fin.
Further, described Z1 expansion set is arranged between described axle and described rotor bushing, makes to produce interaction force between rotor and axle and play locking effect by described expansion set gland extruding.
Further, described common A type key is arranged between described axle and described rotor bushing, plays the effect of transmitting torque power.
Further, described stator core inside is provided with temperature sensor, and when the temperature of described motor internal exceedes predetermined threshold value, described temperature sensor sends alarm signal;
Wherein, described temperature sensor is normally closed thermistor switch.
Compared with prior art, the utility model adopts superior Electromagnetic Design, realizes low rotation speed large torque, and transmission mechanism-free, wear and tear low, assembling is simple, detachable, noise is low, without greasy dirt, operate steadily, precision is high, response is fast, easy care.
Accompanying drawing explanation
