Description
Technical field
The present invention relates to a kind of lathe spindle, synchronize water-cooled electro spindle particularly to one.
Background technology
In lathe equipments, power dragging system is generally divided into mechanical type and electro spindle close-coupled.Commonly use be servomotor or asynchronous machine carrys out driving mechanical main shaft by belt transmission, owing to, in belt transmission, rotating speed is low, vibrations are big, and belt easily skids, and noise is the biggest.Another is electro spindle, and electro spindle is technology motor and main shaft merged, and the rotor of motor is the rotating part of main shaft.Commonly use at present is asynchronous electro spindle, although this kind of form electro spindle overcome the shortcoming that rotating speed is low, vibrations are big, noise is big, but it is because using asynchronous machine, volume is big, the consumption heating of the stator and rotor of motor is big, and efficiency is low, and the situation of watt level of the same race throws switch under lotus is loaded with in impact, ratio is more serious, even stall, causes the performance that cannot play lathe.
Summary of the invention
The technical problem to be solved is to overcome the problems referred to above, and provide that a kind of volume is little, heating less, power big, and vibrate synchronization water-cooled electro spindle little, that precision is high.
The technical scheme is that
A kind of synchronization water-cooled electro spindle, including main shaft and permagnetic synchronous motor assembled thereon, synchronous motor includes rotor assembly, stator module, shell, front gland and rear pressing cover, it is characterized in that: the front-end and back-end of described shell are separately installed with front-end bearing pedestal and rear bearing block, described front gland and rear pressing cover are separately mounted to the outer end of front-end bearing pedestal and rear bearing block；Described stator module is positioned at outer shroud, and including stator core and winding coil windings thereon, described stator core is installed in the enclosure in an interference fit；Described rotor assembly is positioned at internal ring, and including rotor and the permanent magnet being arranged in rotor outer wall, described rotor is arranged on main shaft and corresponding with stator core；Described main shaft respectively by the fore bearing that is arranged on front-end bearing pedestal and after the rear bearing that is arranged on bearing block install in the enclosure, the front end of main shaft is stretched out from shell, and front end is provided with chuck component；It is provided with coolant jacket, described coolant jacket and shell interference fit between described shell and stator core, the outer wall of coolant jacket offers the helicla flute for coolant circulation.
Further, the rear end of main shaft of the present invention is provided with encoder, and described encoder connects the driving motor being driven main shaft.
Further, synchronous motor of the present invention is 18 groove quadrupole motor.
Further, front gland of the present invention includes protecgulum and fore bearing gland, and described protecgulum is arranged on the outer end of fore bearing gland, has male-female engagement face between protecgulum and fore bearing gland, forms labyrinth type mechanical seal structure；Described rear pressing cover includes bonnet and rear bearing gland, and described bonnet is arranged on the outer end of rear bearing gland, has male-female engagement face between bonnet and rear bearing gland, forms labyrinth type mechanical seal structure.
The invention has the beneficial effects as follows:
1, synchronous motor and main shaft are merged, it is achieved directly drive shaft, eliminate running part, reduce main shaft vibration in operation process, improve the precision of product, and be capable of the big torsional requirements of lathe；
2, permanent-magnet synchronous technology is used, compared with asynchronous electro spindle, rotor heating is little, only need to cool down stator, therefore coolant jacket is set outside stator, coolant circulation can realize cooling down, and under same volume, power is 1.5 times of asynchronous electro spindle, equal-wattage lower volume is less than asynchronous electro spindle, saving raw material, and be lost little, efficiency is high；
3, numerically controlled lathe synchronous electric spindle of the present invention adds encoder, can reach smooth running and propose high-precision requirement.
