The content of the invention
The purpose of this utility model is discharged aiming at the deficiencies in the prior art there is provided a kind of drop test with article to be filled
Put, the motor and feed screw nut's driving tongs opening and closing, so that automatic release experiment article can be realized, provide for laboratory automation
Good basis, its simple in construction, function is reliable.
To achieve the above object, the utility model is adopted the following technical scheme that.
A kind of drop test article release device, including the tongs being hinged to by two suspension hooks, the upper end of two suspension hooks
It is hinged with hinged seat, hinged seat and is hinged with connecting rod, small end is hinged on lifting body, provided with electricity drive between two hinged seat
Dynamic screw nut driving structure, the electric drive screw nut driving structure is used to drive two hinged seat relative movements, to be formed
Tongs folding.
Using the utility model of preceding solution, the parallelogram knot of two suspension hooks and two connecting rod formation substantially
Structure, power-actuated hang is formed between two hinge points of control tongs opening and closing by motor and feed screw nut's driving structure
Folding is clamped, realizes that tongs opening and closing are controlled will pass through controlled motor startup, without carrying out manpower driving or pulling tongs, article falls
Fall and realization opened by tongs, be different from it is traditional by article driving tongs open, during tongs opens, two suspension hooks it
Between, and will not form impact between suspension hook and other components and collide, collision deformation hidden danger is eliminated, experiment is improved reliable
The service life of property and device, and simple in construction, function is reliable.
It is preferred that, the electric drive screw nut driving structure includes the motor being fixedly connected by motor installation component,
And by the screw mandrel of motor-driven rotation, screw mandrel is combined with nut, nut periphery forms pivot structure, and nut passes through pivot structure
Two lower articulated jibs are hinged with, two lower articulated jib upper ends correspond to be hinged on described in one on hinged seat respectively, on two hinged seats
Articulated jib is also respectively articulated with, the upper end of two upper articulated jibs is hinged on the motor installation component.Hinged seat passes through
Lower articulated jib driving, rather than feed screw nut's direct drive, to form reinforcing structure, reduction driving power saves energy consumption, reduces knot
Structure volume, reduces manufacturing cost.
It is further preferred that the motor is connected by gear reduction box with the screw mandrel；The case of the gear reduction box
Body constitutes the motor installation component.Power is driven with further reduction, and upper articulated jib is installed using the casing of reduction box, from
And beneficial to compact conformation.
It is further preferred that the hinged seat is handed over provided with suspension hook, connecting rod, lower articulated jib and articulated jib is respectively used to
The four handing-over axles connect.So as to suspension hook, connecting rod, lower articulated jib and upper articulated jib arrangement in the same plane, it is to avoid turn round
Turn phenomenon, it is ensured that article is hung and released movement is steady, improves experimental reliability.
It is further preferred that the lifting body bottom is formed with notching construction, the upper end of two upper articulated jibs is located at
In the fluting.So that upper articulated jib upper end is hidden in fluting, it is to avoid with other component interferences.
The beneficial effect of the utility model compared with prior art is that article release is completed by machine power, can be by right
Hanging items and automatic release are realized in the control of motor, and its simple in construction, compact in design, function is reliable.
