Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of lifting table as shown in Figure 1, comprise symmetrically arranged upper mounting plate 1 and lower platform 2, one group of scissors mechanism 11 is installed between upper mounting plate 1 and lower platform 2, lower platform 2 is also provided with drive motor 3, the motor shaft of drive motor 3 connects reductor, reductor drives a screw mandrel 4 by finishing bevel gear cuter kinematic pair, and the thread rotary orientation on drive motor 3 both sides screw mandrel 4 is contrary; Screw mandrel 4 two ends connect folding stand 5 respectively, each folding stand 5 comprises the screw 51 coordinated with screw mandrel 4, and with upper mounting plate 1, lower platform 2 hinged upper folding hack lever 52 and lower folding hack lever 53, the lower end of upper folding hack lever 52 is connected screw 51 jointly with the upper end of lower folding hack lever 53; Drive motor 3 rear portion is provided with motor rack 31, and motor rack 31 is flexibly connected one group of guide pin bushing 32, and each guide pin bushing 32 coordinates with the pilot bar 33 be located on lower platform 2.Lower platform 2 is evenly arranged four guide rods 6, and each guide rod 6 lower end, through lower platform 2, guide rod 6 is set with Compress Spring 61.On each, the end of folding hack lever 52 is provided with stop collar 54, accordingly, each lower folding stand 5 bar has the position-limited trough 55 corresponding with stop collar 54.Folding stand 5 is separately positioned on the inner side of scissors mechanism 11, and motor drive motor 3 can be made like this to be positioned at the middle part of lower platform 2, makes whole lifting table keep Equilibrium.
Upper mounting plate 1 and lower platform 2 are provided with slideway 7, in two groups of strut bars of two scissors mechanisms 11, the end of one group of strut bar is had at least to be arranged in slideway 7, the strut bar end be arranged in slideway 7 is also provided with slide block 71, be provided with the slide bar 72 coordinated with slide block 71 in slideway 7, slide block 71 can slide on slide bar 72; Between each group of strut bar, be provided with transverse support bar 8, transverse support bar 8 can arrange 4.
A kind of lifting table of the present utility model, be applied in the automatic guided vehicle of prior art, operationally, drive motor 3 drives screw mandrel 4 to rotate, and screw mandrel 4 is when rotating, and the screw 51 that its two ends connect can in opposite directions or opposing motion, when screw 51 move toward one another, it pulls folding hack lever 52 to move with lower folding hack lever 53, and the distance now between upper mounting plate 1 and lower platform 2 reduces, and upper mounting plate 1 highly declines; When the opposing motion of screw 51, it promotes vertical folding superimposed 5 bar and lower folding stand 5 bar moves, and the distance now between upper mounting plate 1 and lower platform 2 increases, and upper mounting plate 1 highly rises.Lower platform 2 installs four guide rods 6, guide rod 6 is set with Compress Spring 61, when upper mounting plate 1 move downward with each guide rod 6 top contact after, it continues to move downward promotion guide rod 6 and moves downward simultaneously, Compress Spring 61 is produced antagonistic force upwards by compression, can play the effect of the vibrations reduced when upper mounting plate 1 moves downward, and the lift that can exist when lifting mechanism is in minimum shut height is upwards inadequate, carries out the compensation of power with the compressive force that Compress Spring 61 produces.
On each, the end of folding stand 5 bar is provided with stop collar, accordingly, each lower folding stand 5 bar has the position-limited trough corresponding with stop collar, the combination of stop collar and position-limited trough, when object is to avoid drive motor 3 to drive upper mounting plate 1 upward movement, motion exceeds and limits position and the screw mandrel 4 that causes departs from screw 51 problem be connected.
