Description
Technical field
The invention belongs to vehicle crash test fields, more particularly, to a kind of automatic straightening device of impact test vehicle.
Background technique
With the development of vehicle passive safety technology, impact test is increasingly paid attention to by enterprise, and experiment quantity is increasingly
More, the requirement to collision test accuracy is also higher and higher, and spot cars is as an important step in test preparation process, to test
Precision has a significant impact.
Currently, both at home and abroad about the application of Automobile turntable mainly in the related neck such as vehicle inspection and test station, automobile factory
Domain.This type Automobile turntable has formed more mature product, but its volume is larger, general irremovable, is not suitable for vapour
Vehicle collides field.In impact test at this stage, more universal spot cars method is more original, need to expend many manpowers and
Physical strength does not meet the efficient working method of modernization.For example, the coating butter between two blocks of steel plates, is placed in upper layer for vehicle
On steel plate, by pushing vehicle to drive the movement of upper layer steel plate in vehicle side, it is made to have relative vehicle y-axis direction with lower layer steel plate
Sliding adjusts the position of vehicle relative orbit, ajusts to realize.The existing Automobile turntable that can be used in impact test
There are problems, such as: the degree of automation is inadequate, needs first manually to shift vehicle on relatively high straight-putting unit onto, cause high effort for；
Since mobile scheme is unreasonable, cause frictional force larger, motion credibility is inadequate etc..It is therefore desirable to be tried for car crass
A kind of automobile straightening device of Portable durable of Site Design is tested, to cater to fast-developing vehicle passive safety technical requirements.
Chinese patent literature CN204116019U, discloses a kind of Weighing type Automobile turntable, and the invention is in use more
To be reliable, structure is simpler, suitable for the Weighing type Automobile turntable of various vehicle wheel bases, including front axle mobile platform, institute
It states front axle mobile platform and is equipped with the near front wheel weighing plate and off-front wheel weighing plate, the near front wheel weighing plate and off-front wheel weighing plate
Four angles be respectively arranged below with a weighing sensor；The weighing sensor connects a calculator.Of the invention is excellent
Point is not to be afraid of car crass without protrusion motive objects on front axle mobile platform and roll, while improving the safety of workshop operator
Property.But equipment involved in the invention is built-in type, irremovable, is not suitable for impact test field.
Chinese patent literature CN205538246U discloses a kind of motorcar electric straight-putting unit, comprising: pedestal；Power source,
It is detachably mounted on the pedestal；First sliding panel is arranged under the wheel of the automobile, in the drive of the power source
Under dynamic, it can be moved along the transverse direction of automobile；Another wheel coaxial with the wheel is arranged in second sliding panel
Under.The present invention have the characteristics that compact structure flexibly, be easily installed use, ajust it is high-efficient.But equipment involved by the invention is certainly
Dynamicization degree is still not high enough, needs to shift vehicle onto straight-putting unit up first with manpower, and since straight-putting unit is higher, thrust is very big,
There is no fundamentally improve labor efficiency；It is not reasonable additionally, due to sliding pair conceptual design, during actual use reliable
Property is inadequate, stuck phenomenon often occurs.
It is a kind of lighter reliable therefore, it is necessary to design, it more automates, really is able to realize can be used for for one man operation
The automatic straightening device of the automobile of impact test.
Summary of the invention
In view of this, the present invention is directed to propose a kind of automatic straightening device of impact test vehicle, solves existing ajust
The problems such as plant automation degree is low, volume is larger, and be a kind of automatic straightening device of the automobile that can be used for impact test.
In order to achieve the above objectives, the technical scheme of the present invention is realized as follows:
A kind of automatic straightening device of impact test vehicle, including the front part of vehicle straight-putting unit being oppositely arranged and vehicle rear
