2 the 3rd strong point 23.Wherein, fixed support portion 6 is by the base for being fixed on the first supporting plate 4 and the support being fixed on base
Bar is constituted, and it is highly unadjustable；Both heights governor motion 5 it is Height Adjustable, electrically connected with PLC control unit respectively, by
PLC control unit is controlled.
Switch of inclination (not shown) is also installed with first test panel 2, the switch of inclination controls single with PLC
Unit communicates to connect, and the angle of inclination information for the first test panel of real-time detection 2 simultaneously sends this information to PLC control lists
Unit.In the present embodiment, switch of inclination is located at the lower surface of the first test panel 2.
PLC control unit, it is electrically connected with switch of inclination, both heights governor motion 5, for according to switch of inclination
Detection information judges the heeling condition of the first test panel 2, carries out height regulation control to both heights governor motion 5 automatically, makes
Obtain the first test panel 2 and recover horizontality.
Based on above-mentioned to three compositions for being distributed design and level(l)ing mechanism of the strong points, the present embodiment use only
Two height adjustment mechanisms 5, compared with using three height adjustment mechanisms or other strong points distribution design, can be most
The calculation procedure of big degree ground optimization PLC control unit, reduces the amount of calculation during whole Level tune, regulation of improving the standard
Efficiency and precision.
For convenience of safeguarding, PLC control unit is installed in the second supporting plate 7, and the second supporting plate 7 is fixed in frame 1,
And positioned at the lower section of the first supporting plate 4.
The Level tune process of above-mentioned automatic level adjusting device is specially：
The angle of inclination of the first test panel of switch of inclination real-time detection 2 the 1st, being installed on the first test panel 2, and will
The information transmission is to PLC control unit.
2nd, PLC control unit controls the first height adjustment mechanism 5 and the second height to adjust according to the transmission information of switch of inclination
Section mechanism 5 carries out corresponding height regulation so that second strong point 22 and the 3rd strong point 23 move up and down, until switch of inclination is examined
The first test panel 2 is measured to recover to horizontality.
To sum up, the horizontality that the present embodiment passes through the first test panel of switch of inclination monitor in real time 2, by PLC controls
Unit carrys out the work of controlled level governor motion so that the moment of the first test panel 2 is maintained at horizontality, overcomes manually
The existing defect that difficulty is high, accuracy rate is low of regulation.
