Also hollow major diameter (especially hollow diameters 150mm and more than) and high rotating speed (600r/min) requirement can not be accomplished.It is existing
Hollow industrial turntable is mostly very heavy, and overall volume is larger, and power consumption is high.When load is eccentric structure, it is impossible to regulation weight
Vibration equipment is larger during the heart, use, produces the abrasion of larger noise and equipment.
The content of the invention
It is an object of the invention to：The problem of existing for prior art solves existing there is provided a kind of hollow eccentric turntable
Have that industrial turntable is very heavy, overall volume is larger, the problem of power consumption is high.
The goal of the invention of the present invention is achieved through the following technical solutions：
A kind of hollow eccentric turntable, the turntable includes base, support frame, bearing, rotary shaft, motor, rotating frame
With load retainer ring, the bottom of support frame as described above is fixed on base, and the top of the support frame is circular support, and the bearing is consolidated
It is scheduled in circular support, the rotary shaft is connected on bearing inner race, one end connection motor of rotary shaft, other end connection rotation
Framework, the load retainer ring is connected on rotating frame.
As further technical scheme, the turntable includes center of gravity regulating block, and the outer ring of the rotating frame is provided with weight
Heart regulating block mounting hole.
As further technical scheme, the bearing is fixed by many muscle with circular support.
As further technical scheme, the motor is fixed on support frame by motor fixing frame.
As further technical scheme, in a ring, it connects rotary shaft to the rotating frame by many muscle.
Compared with prior art, the present invention has advantages below：
1st, simple in construction, small volume is lightweight；
2nd, load eccentric structure, gravity-center adjustable to axis of rotation are rotated；
3rd, rotating speed is adjustable, and maximum speed is up to 600r/min；
4th, rotary hollow blocks small, and glazed area is big.
Brief description of the drawings
Fig. 1 is eccentric turntable overall structure figure；
Fig. 2 is eccentric turntable side perspective view；
Fig. 3 is that motor control connects block diagram.
Embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
The present invention provides a kind of eccentric rotation table device, as shown in FIG. 1 to 3, including base 1, support frame 2, center of gravity regulation
Block 3, loads retainer ring 4, rotating frame 5, reducing motor and control line 6, and motor fixing frame 7, bearing 8, rotary shaft 9 is constituted.Bottom
1 size of seat is 170mm × 70mm × 8mm square plate, and has reserved multiple mounting hole sites.The lower part of support frame 2 passes through spiral shell
Nail connected mode is fixed on base, and the upper part of support frame 2 is a circular support, and its largest outer diameter is 160mm, inner ring
Hollow diameters 150mm, central fixed shaft bearing portion is divided into square, and size is 25mm × 25mm, is 3mm by three thickness, wide
The muscle support for spending 28mm is fixed.Rotary shaft 9 is rigidly connected (interference fit) on the inner ring of bearing 8, and bearing 8 is arranged on support frame 2
Hollow part.One end of rotary shaft 9 is connected with reducing motor, and reducing motor is fixed on into support by motor fixing frame 7
Transmission is connected on frame 2 with rotary shaft 9, the other end of rotary shaft 9 is connected with rotating frame 5, is fixed using screw, with this
Rotating frame is driven to rotate.The interior hollow diameters 150mm of rotating frame 5, the step trough that inner ring has been 156mm is used to install negative
Carry, rotating frame 5 be connected with rotary shaft 9 core size be diameter 25mm thickness 8mm, by three muscle by outer shroud with it is interior solid
Fixed part is connected.An outer ring part for rotating frame 5 has reserved the mounting hole site of center of gravity regulating block；Load to use external diameter
156mm wedge-shaped polytetrafluoroethylmaterial material lens (lens cannot through visible ray and some other frequencies electromagnetic wave,
But the electromagnetic wave of certain certain frequency can be passed through), it will be loaded admittedly inside rotating frame, and by loading retainer ring 4
It is scheduled on rotating frame 5.
The hollow diameters Φ 150mm areas of turntable are 17671mm2, wherein shield portions area is 1188mm2, block
The area ratio that part accounts for whole hollow region is 6.7%, it is seen then that turntable is smaller to blocking for wave beam, the electromagnetism of certain certain frequency
The transmission area of wave beam is larger, meets application demand.
Mounting hole site is reserved with base 1, facilitates the installation of different usage scenario intermediate stations, base area is larger, can be with
Ensure the work of turntable long-term smooth；Support frame 2 is fixed on base 1 by multiple mounting hole sites using screw；Rotary shaft 9
It is rigidly attached on the inner ring of bearing 8, the outer ring of bearing 8 is fixed on the centre of support frame 2；One end of rotary shaft 9 and deceleration
Motor 6 is connected, and reducing motor 6 is fixed on support frame 2 by reducing motor fixed mount 7 is connected transmission with rotary shaft 9；It is logical
The other end that rotating frame 5 is fixed on rotary shaft 9 by four screws is crossed, to drive rotating frame 5 to rotate；Eccentric wedge load
Lens are fixed on rotating frame 5 by loading retainer ring 4.Turntable can be directed to different eccentric load (position of centre of gravitys
Difference), the center of gravity of irregular eccentric wedge load lens is adjusted using center of gravity regulating block makes it on rotation axis, mitigates
Due to the wear problem that eccentric moment is brought during rotation, being rotatably assorted for support shaft is effectively protected, reduce vibration and make an uproar
Sound.
Further, rotated using motor drive module motor by desired speed, can be according to specifically used
Need, change the rotary speed of turntable, maximum speed can reach 600r/min.Motor drive module includes torque servo control
System, Speed servo control, motor control connection block diagram is as shown in Figure 3.Torque Control actually current control, it is real using PI controllers
Existing motor torque control, while providing overcurrent protection function；Speed servo control module, which is used, carries feed forward of acceleration and speed
The PI controllers of feedforward control speed, and motor speed measured by the encoder of motor afterbody.
In summary, the invention provides a kind of hollow eccentric turntable, the workbench of the turntable passes through such as Fig. 1 institutes
The vertical support frame shown is arranged on the base of horizontal positioned；Limited by the rotation axle allocation mechanism as shown in side perspective Fig. 2
Rotating frame processed and load rotate around its center；Driven simultaneously by drive control scheme as shown in Figure 3 using motor
Dynamic rotational structure rotates.The intermediate link of turntable described by this patent is few, fast response time, lightweight, reduction
Vibration, noise and abrasion.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, it is noted that all
