Hold in the palm and be fixed on the supporting table, in this way, the stability of turntable bearing 30 can be lifted, reduce abrasion, improve the service life.
The turntable bearing 30 that the present invention selects has a radial rolling part 331 of row (being used to bear radial load) and two row axis
To rolling member 333 (being used to bear axial load), in this way, turntable bearing 30 can be reduced in the rotational variations in other directions, so that
Add turntable bearing 30 and bear load capacity and stability, such setting in radial and axial, while can also improve
The straight precision for turning platform 100, you can so that straight axial runout and circular runout its precision control within the specific limits for turning platform 100
System is in the micron-scale.
Further, the stator 10 is equipped with sensor 51, and the internal rotor 70 is equipped with trigger 71, the triggering
Device 71 is rotated with the internal rotor 70 has dead-center position, and the trigger 71 triggers the sensor when dead-center position
51。
Specifically, circuit board 50 is arranged at the end that stator core 11 deviates from fixed plate 151, and sensor 51 is fixed on circuit
Plate 50 is towards the surface of fixed plate 151, and sensor 51 is set close to internal rotor 70, its fixed form can be welding, also may be used
To be other effective fixed forms of cementing grade.Trigger 71 is fixed on the outer surface of internal rotor 70 and is set close to circuit board 50
Put, trigger 71 has dead-center position, trigger sensor when dead-center position of trigger 71 during being rotated with internal rotor 70
51.Using this position as zero reference point, worked normally every time since this position in this way, may be such that and directly turn platform 100.This hair
Bright middle trigger 71 is catch, and when internal rotor 70 turns to dead-center position, catch contact and trigger sensor 51, sense certainly
The type of device 51 can also be contactless；
In the present embodiment, three sensors 51 are provided with circuit board 50, three sensors 51 are along the week for directly turning platform 100
To being spaced apart, if in this way, one of them is abnormal, next sensor 51 can be directly switch to and worked normally, from
And effective guarantee directly turns the zero of platform 100, while it can also avoid frequently dismounting and replace, provide to the user conveniently.
In addition, directly turning the reset mode that platform 100 is also provided with encoder 73, specifically, encoder 73 is fixed on interior turn
Son 70 is towards the end face of fixed plate 151, and at this time, the middle part of fixed plate 151 opens up jagged 1513, and notch 1513 connects fixed cylinder
153 are set, and encoder 73 is placed in notch 1513, and encoder 73 is rotated into row data acquisition to internal rotor 70, and by number
Control system is passed to according to corresponding electric signal is converted into, so that control system accurately controls straight for turning platform 100
Stop bit is put.In this way, two kinds of reset mode synergistic effects, common cooperation, make the control for directly turning platform 100 more accurate, reliability
Higher.
The foregoing is merely the preferred embodiment of the present invention, is not intended to limit the scope of the invention, every at this
Under the inventive concept of invention, the equivalent structure transformation made using description of the invention and accompanying drawing content, or directly/use indirectly
It is included in other related technical areas in the scope of patent protection of the present invention.
