Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of headstock.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, a kind of Digit Control Machine Tool of electric machine built-in, comprises base 100, workbench 200 and headstock 300, and workbench 200 and headstock 300 are arranged on base 100.
Referring to Fig. 2, headstock 300 comprises casing 310 and is arranged at main shaft 320, stator 330, rotor 340 and the coil 350 in casing 310, and rotor 340 is arranged on main shaft 320, and stator 330 is arranged at outside rotor 340, and coil 350 is arranged on stator 330.When using, the coil 350 on stator 330 is switched on, and rotor 340 is magnet, and therefore, under the induction in magnetic field, rotor 340 drives main shaft 320 to be rotated, thereby carries out work.
The two ends of casing 310 are respectively arranged with clutch shaft bearing 410 and the second bearing 420, the two ends of main shaft 320 are connected with the second bearing 420 and with clutch shaft bearing 410 and the second bearing 420 through the clutch shaft bearing 410 at casing 310 two ends, and clutch shaft bearing 410 and the second bearing 420 can steadily rotate main shaft 320.
Stator 330 is fixedly connected on the inwall of casing 310, between stator 330 and rotor 340, is provided with gap.
Clutch shaft bearing 410 is arranged on casing 310 towards one end of workbench 200, on casing 310, towards one end of workbench 200, is also provided with bearing door closure 360, and clutch shaft bearing 410 is arranged in bearing door closure 360.Because casing 310 is provided with the opening for inner components is installed towards one end of workbench 200, therefore clutch shaft bearing 410 is difficult to install, and bearing door closure 360 is first arranged on opening part, and then clutch shaft bearing 410 is arranged on bearing door closure 360, so just overcome above-mentioned this problem, simultaneously because bearing door closure 360 is for the detachable opening part of casing 310 towards one end of workbench 200 that be connected to, therefore also very convenient to inner part replacement, maintenance.
