The vehicle rear lower part protection test bed can judge whether the surface of the loading block is strictly at grade with a surface of a device detected through the switching state of the microswitches, and can improve the accuracy of test.
Description
Technical field
The utility model belongs to the motor vehicle detecting technical field, relates to a kind ofly being used to test the rear lower protective device or relying on the profile of self and the testing table of characteristic car body, frame part or other parts that can have the vehicle of rear lower safeguard function.
Background technology
Rear lower protection test platform is when testing, require the loading blocks surface and the strict maintenance level in tested device surface of protection test platform, existing rear lower protection test platform at the trial, can only observe whether level of the loaded surfaces of protection test platform and tested device surface by operating personnel, because there is certain error in range estimation, the result to test will affect like this.
Summary of the invention
The purpose of this utility model: be to overcome deficiency of the prior art, propose the whether rear lower protection test platform of level of a kind of loaded surfaces that can judge rear lower protection test platform automatically and tested device surface.
For this reason, the utility model adopts following technical scheme.
A kind of vehicle rear lower protection test platform, comprise industrial computer, with the PLC switch board that links to each other by communication module between the industrial computer, thrust unit, described thrust unit comprises and is subjected to the motor-driven electric pushrod of boosting mechanism, be fixed on the loading blocks in the described electric pushrod mechanism, be used to detect the loading blocks displacement and displacement signal is delivered to the displacement transducer of PLC switch board, the workplace of described loading blocks is provided with the microswitch more than three or three.
As preferred implementation, described testing table also comprises height control mechanism, and described height control mechanism is subjected to the control of PLC switch board, is used to adjust described thrust unit height.
Compared with prior art, the beneficial effect that the utility model had is: use range estimation to judge loading blocks surface and rear lower protective device or rely on self profile and the characteristic car body that can have the vehicle of rear lower safeguard function at existing equipment, whether frame part or other parts surface level, because there is certain error in range estimation, may cause when beginning to test, because the loading blocks surface does not keep level with the tested device surface, the power that is applied to the tested device surface when causing testing is unbalanced, the data that record like this influence the degree of accuracy of measuring with inaccurate.The utility model has been installed four microswitches on loading blocks, have like this by the on off state of microswitch to judge whether strict level of loading blocks surface and tested device surface, can improve test accuracy.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model;
Fig. 2 is the synoptic diagram of loading blocks working surface of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Rear lower protection test platform is to be used to test the rear lower protective device or to rely on the profile of self and a kind of proving installation of characteristic car body, frame part or other parts that can have the vehicle of rear lower safeguard function, be used for estimating the rear lower protective device or rely on self profile and characteristic can have the vehicle of rear lower safeguard function car body, frame part or other parts after being subjected to external force collision, can be up to state standards requirement.This system is made of hardware system that is used to test and control corresponding software
As shown in Figure 1, the utility model testing table comprises hardware and the control corresponding software composition that is used for industrial computer, ADAM-4520 communication module, PLC switch board, thrust unit and height control mechanism composition.
Thrust unit comprises and is subjected to the motor-driven electric pushrod of boosting mechanism, is fixed on the loading blocks in the described electric pushrod mechanism, the displacement transducer that is used to detect the loading blocks displacement and displacement signal is delivered to the PLC switch board.On the loading blocks of 200mmX250mm, bore four apertures and (also can only bore 3 apertures, perhaps bore more hole), a microswitch is installed respectively in four apertures, like this at loading blocks surface and rear lower protective device or rely on self profile and the characteristic car body that can have the vehicle of rear lower safeguard function, when frame part or the contact of other parts, loading blocks surface and rear lower protective device be can the on off state by microswitch judge or self profile and the characteristic car body that can have the vehicle of rear lower safeguard function relied on, whether frame part or other parts surface strict level, can effectively guarantee the smooth implementation measured, referring to Fig. 2.
The surface of tested device is placed on the position parallel with the loading blocks surface fixes, power on for the PLC switch board, open industrial computer then, the running control software thrust unit comprises and is subjected to the motor-driven electric pushrod of boosting mechanism, be fixed on the loading blocks in the described electric pushrod mechanism, be used to detect the displacement transducer of loading blocks displacement.Testing procedure is as follows:
1 by " crawl advances " button in manual operation button on the PLC switch board or the click Control Software, the control motor is pushed ahead slowly, when loading blocks surface with after the tested device surface contact, can learn whether strict level of the surperficial and tested device surface of loading blocks by the on off state of four microswitches.If four microswitches are opened simultaneously, loading blocks surface and the strict maintenance level in tested device surface are described, just carry out the 3rd step.If four microswitches are not opened simultaneously, illustrate that the loading blocks surface is not a horizontality with the tested device surface, just carry out the 2nd step
2 by " crawl moves back " button in manual operation button on the PLC switch board or the click Control Software, the control motor advances slowly backward, allow the loading blocks surface disengage with the tested device surface, finely tune the tested device surface according to the on off state of four microswitches then, do the 1st step then again.
3 inputs are used for stopping automatically loading stops the loading force value, clicks " advancing " button then, begins test.
In experimentation, Control Software is presented at data in real time such as loading force and displacement in the chart in the Control Software upper right corner.When test, if the loading force that loads has surpassed when stopping loading force, will stop motor automatically, if not surpassing, the loading force that loads do not stop loading force, but displacement has surpassed test request, and this moment, operating personnel can require according to the producer of tested device to select to stop motor or continue loading.
After off-test, the data with record are kept in the corresponding file simultaneously, are provided with post analysis and use.
