Embodiment
With reference to Fig. 1-3, the present invention is described in detail.
Table apparatus is supported according to a kind of equipment of accurate adjustment of embodiment, including fixed pedestal 2, is arranged on the fixation
The equally distributed four lift adjustment components 7 of circumference and the support supported by four lift adjustment components 7 on pedestal 2
Platform 30, wherein, each in four lift adjustment components 7 includes being slidably matched with the fixed pedestal 2 and can be in footpath
Sliding support 73 to square upward sliding, the lifting screw with the screwed hole screw thread cooperation in the upper surface of the sliding support 73
72nd, the articulated joint 721 being connected with the upper end of the lifting screw 72 by bearing and the connected and position with the lifting screw 72
Screw rod tooth set 71 between the upper surface of the sliding support 73 and the articulated joint 721, the articulated joint 721 passes through ball pivot
Chain and be connected with the supporting table 30, wherein, the lower end of the lifting screw 72 of each lift adjustment component 7 is freely
Hold, be fixedly installed drive installation platform 5 on the fixed pedestal 2, the middle part of the drive installation platform 5 is slidably mounted
There is motor mounting seat 8, the motor 9 coupled with the power of drive gear 91 be supported with the motor mounting seat 8,
The outer surface of motor 9 is provided with radiating fin 92, and the radiating fin 92 is laterally set, and with the motor 9
It is fixedly connected, the radiating fin 92 prevents the driving electricity the motor 9 is run into caused heat absorption
Machine 9 burns because long-play temperature is too high, wherein, orthogonal two groups of bearing of trend are provided with the drive installation platform 5
Chute 50,51, one in four screw rod tooth sets 71 is driven to guide the slip of the motor mounting seat 8
It is dynamic;Every group of two sections of cunnings for including the opposite sides positioned at the motor mounting seat 8 in two groups of chutes 50,51
Groove, and electromagnetic actuator device 63,31 is provided with one section in two sections of chutes, be provided with another section flexible restoring organ 6,
32, the flexible restoring organ 6,32 includes the sleeve 60 for being fixedly connected on the drive installation platform 5 and by elastic multiple
Bit unit 61 and the pull bar 62 coordinated with the Elastic Sliding of sleeve 60, the head of the pull bar 62 is provided with slip and matched somebody with somebody
To be slidably matched with the push-and-pull chute 80 in the corresponding side surface of the motor mounting seat 8, this is slidably matched fair syncephalon 621
Perhaps described motor mounting seat 8 is axially slided relative to the pull bar 62 on orthogonal direction, the motor peace
Permanent magnet 64,3 to be interacted with the electromagnetic actuator device 63,31 is installed in dress seat 8;Wherein, the extension side
To orthogonal two groups of chutes 50,51, corresponding permanent magnet 64, about 3 is provided separately respectively, thus, when positioned at different height
Electromagnetic actuator device 63,31 in one it is upper electric when, enable to permanent magnet 64,3 at respective heights by repulsive force, so as to
Enable to the pull bar 62 to push the elastic reset member 61 and cause the drive gear 91 and corresponding screw rod tooth
The engagement of set 71, and when reversely going up electric, the permanent magnet 64,3 at the respective heights is enabled to by attraction, so as to make
The pull bar 62 is obtained to stretch the elastic reset member 61 and cause the drive gear 91 and another corresponding screw rod tooth set
71 engagements, when instantly electric, by the reset response of the elastic reset member 61, the motor mounting seat 8 is at
Centre position, so that the drive gear 91 departs from each screw rod tooth set 71.
Valuably or exemplarily, wherein, the motor mounting seat 8 is made up of magnetic isolation material.
Valuably or exemplarily, when the motor mounting seat 8 is slided in the selected direction, bearing of trend is with being somebody's turn to do
The consistent pull bar of preferential direction is slidably matched first 621 positioned at the centre of corresponding push-and-pull chute 80, and bearing of trend is with being somebody's turn to do
Being slidably matched for the orthogonal pull bar of preferential direction first 621 remains slip with corresponding push-and-pull chute in sliding process
Coordinate.
Valuably or exemplarily, wherein, described be slidably matched first 621 includes at least with the cooperation of the push-and-pull chute 80
One plane coordinates, to prevent the motor mounting seat 8 from first 621 being rotated relative to described be slidably matched.
The radial direction refers to the radial direction of circumference corresponding with the circumference.Radially slided using this, actually existed
Slip on two orthogonal axis, therefore, when two sliding supports on an axis enter line slip, orthogonal another
Two sliding supports on axis are in stationary state(It can not slide), it is consequently formed reliably secure hinged support.The cunning
The slip of dynamic support can be oriented to by the corresponding chute 100 radially extended.
, can be by adjusting the height size of lifting screw, so as to the water to supporting table by the said apparatus of the present invention
Flat inclination angle is adjusted.Moreover, this Adjust and use reseting performance of elastic reset member, and with the use of calutron
Bidirectional force applying performance, so as in one axial direction only set an electromagnetic drive on the basis of realize promote, pull,
Reset three kinds of functions.And by the way that the driving reset assembly in orthogonal both direction is arranged to separate in the vertical direction,
So as to avoid mutual stress from disturbing.Whole device is easy to use, regulation is accurate and is easy to safeguard, reduces whole equipment
Use cost and manufacturing cost.Efficiently solve the problems of the prior art.
By that can be made within the scope of the invention according to mode of operation various with upper type, those skilled in the art
Change.
