[0002] In lathe equipment, the power drag system is generally divided into mechanical type and electric spindle compact type. Servo motor or asynchronous motor is commonly used to drive the mechanical spindle through belt transmission. Due to the low speed and large vibration in belt transmission, and the belt It is easy to slip, and the noise is relatively large. The other is the asynchronous electric spindle. Although this type of electric spindle overcomes the shortcomings of low speed, large vibration, and high noise, because it uses an asynchronous motor, the rotor generates heat and the efficiency is high. Low, and in the case of the same power, the loss of rotation is serious under the impact load, or even stalled, resulting in the inability to exert the performance of the machine tool

The invention relates to a motorized spindle structure of a numerical control lathe. The motorized spindle structure comprises a spindle case, a spindle front bearing, a spindle, a cooling liquid inlet, a spindle front bearing seat, a front bearing cooling jacket, a stator, a rotor, a stator cooling jacket, a cooling liquid outlet and a spindle rear bearing. A front end cover and a rear end cover are arranged at the two ends of the spindle case respectively in a connection mode through tension bolts. The spindle front bearing seat and a spindle rear bearing seat are arranged at the two inner ends of the spindle case respectively. The spindle front bearing is arranged on the spindle front bearing seat in a connection mode, a spindle rear bearing is arranged on the spindle rear bearing seat in a connection mode, and the spindle front bearing and the spindle rear bearing are matched and provided with the spindle in a connection mode. The motorized spindle structure is simple, the product precision is improved, losses are small, and the efficiency is high; through a non-contact rotary encoder, friction and abrasion are avoided, and the motorized spindle structure of the numerical control lathe is small in size, low in weight, compact in mechanism and convenient to mount.
