Object is from vertically to the attitude orthogonal transformation of level, to meet the special requirement to object attitude of some production line.
Compared with prior art, the beneficial effects of the present invention is, according to limited constraint space and the requirement to position and attitude at the whole story, to four
The size of linkage is optimized design, and has planned object movement locus in lifting process.
Compared with prior art, the beneficial effects of the present invention is, described mechanism, using electric pushrod as power source, has fast response time,
Reliability of positioning is high, impacts little, service life the advantage such as length.
Compared with prior art, the beneficial effects of the present invention is, described mechanism structure is compact, simple and reliable.
Compared with prior art, the beneficial effects of the present invention is, described automatic mechanism degree is high, saves artificial, easy to maintenance.
The simple change of those skilled in that art and replacement are all within protection scope of the present invention.

22, the 7th bearing pin 23, catch 24, object 25, bolt 26.
Fig. 1 is that the axle of lifting mechanism surveys view, and pedestal 10 is fixed on base plate 11, rocking bar 18, left connecting plate 21, right connecting plate 22, master
Pivoted arm 4, pedestal 10 are hinged by first bearing pin the 2, second bearing pin the 5, the 3rd bearing pin the 7, the 6th bearing pin 19, form one based on rocking bar 18
The four-bar linkage of moving part.Electric pushrod 15 is as the power source of driving link 18, and its root is by the 4th bearing pin 13, support seat 12 and base plate
11 connect；Its expansion link is articulated with the middle part of rocking bar 18 by the 5th bearing pin 16.The expansion link elongation of electric pushrod 15, with drive rocker 18 turns
Dynamic, and then drive whole four-bar mechanism to make plane motion.Grasping device 1 by the first bearing pin the 2, the 7th bearing pin 23 and left connecting plate 21, right be connected
Plate 22 is connected, and its Main Function is fixing object 25.When four-bar mechanism moves, object 25 is with relative according to each rod member of four-bar mechanism of grasping device
Length relation realizes from vertically to posture changing and the lifting of height of level.Angular transducer 9 is fixed on the 3rd bearing pin by sensor installation seat 8
At 7, for measuring the anglec of rotation of main pivoted arm 4.
Fig. 2 is the structural representation of the 6th bearing pin 19 hinged place, and the 6th bearing pin 19 is through pedestal 10 and rocking bar 18, and catch 20 snaps in the 6th
In the groove of bearing pin 19, it is bolted on 26 sidewalls being fixed on rocking bar 18 simultaneously.6th bearing pin 19 is connected by interference fit with rocking bar 18, with
