The automatic verification instrument for speedometer checkout console is simple and ingenious in structure design, high in automation, and capable of reducing error and fault caused by manual operation, so that the verification result is more objective and accurate, therefore the automatic verification instrument for speedometer checkout console may be widely used in verification process of automobile speedometer checkout console.
Description
Technical field
The utility model relates to a kind of detecting instrument, particularly about a kind of automatic calibrating instrument that the automotive speedometer check-out console is examined and determine of being used for.
Background technology
The whole world is possessed automobile and is reached tens00000000, nearly hundred million in annual new production automobile, all dispatch from the factory and all will carry out the check of automotive speedometer with car, the automotive speedometer that is used for this check is checked up to ten thousand of Deltas, in order to ensure the accuracy of these Equipment Inspections and the reliability of use, must examine and determine every year to the automotive speedometer check-out console.The existing method that the automotive speedometer check-out console is examined and determine is that automobile is left the speedometer check-out console of getting on the car, by the Control of Automobile throttle, drive speedometer check-out console cylinder by automobile driving wheel and rotate, utilize the non-contact type tachometric table to measure the check-out console drum rotation speed simultaneously.In the verification process, for the speed of a motor vehicle being stabilized in a certain specialized range, higher to the accuracy and the stability requirement of gas control, vehicle speed value is difficult to stablize usually, generally wants three people could finish this calibration operation, takes time and effort, accuracy is not high.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of minimizing manually-operated, and calibrating speed is fast, and verification result is objective and accurate, can carry out the calibrating instrument of automatic Verification to the automotive speedometer check-out console.
For achieving the above object, the utility model is taked following technical scheme: a kind of speedometer check-out console automatic calibrating instrument, and it is characterized in that: it comprises driving wheel assembly and computer control system; Described driving wheel assembly comprises that one is arranged on the frequency modulation motor on the frame, and the output terminal of described frequency modulation motor connects a driving wheel, and the axle head of described driving wheel is provided with the scrambler that is used to export described driving wheel rotating speed; The input end of described computer control system connects the described scrambler in the described driving wheel assembly, and the output terminal of described computer control system connects the described frequency modulation motor in the described driving wheel assembly.
The utility model is owing to take above technical scheme, it has the following advantages: 1, the utility model starts frequency modulation motor by computer control system, frequency modulation motor drives driving wheel and rotates, and then the cylinder of driving automobile speedometer check-out console rotates, and in real time the tachometer value of driving wheel is fed back to computer control system by scrambler, regulate the rotating speed of frequency modulation motor by computer control system, and then the tachometer value of controlling and driving wheel is stabilized in certain predetermined value, the utility model automaticity height, error and the error of having avoided artificial Control of Automobile throttle to bring make verification result quicker, objective and accurate.2, therefore the utility model, can calculate verification result by instant analysis by computer control system collection and the real-time rotating speed of handling driving wheel, saves artificial post-processed, realizes on-the-spot output verification result.The utility model structure is provided with simply ingenious, and the automaticity height can reduce error and error that manually-operated causes, makes verification result more objective and accurate, therefore, can be widely used in the verification process of automotive speedometer check-out console.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1, the utility model comprises driving wheel assembly 1 and computer control system 2.
The input end of computer control system 2 connects the scrambler 14 in the driving wheel assembly 1, and output terminal connects the frequency modulation motor 12 in the driving wheel assembly 1.
As shown in Figure 2, the course of work of the present utility model is:
1) driving wheel assembly 1 is arranged on the erecting frame 3 by frame 11, erecting frame 3 can be fixed on the automobile also can be fixed on ground, and erecting frame 3 is also different because of the different structure of fixed position, and erecting frame 3 belongs to prior art, no longer describes in detail at this.
2) erecting frame 3 is put down after, driving wheel 13 is pressed on the cylinder 4 of automotive speedometer check-out console, and makes the parallel axes of driving wheel 13 and cylinder 4;
3) computer control system 2 starts frequency modulation motor 12, frequency modulation motor 12 rotates by the cylinder 4 of driving wheel 13 driving automobile speedometer check-out consoles, simultaneously, the scrambler 14 by driving wheel 13 axle head settings feeds back to computer control system 2 with the tachometer value of driving wheel 13;
4) rotating speed of computer control system 2 real-time regulated frequency modulation motors 12 makes the tachometer value of driving wheel 13 be stabilized in certain predetermined value, reads the displayed value of automotive speedometer simultaneously, finishes all testings by the vertification regulation requirement successively, and the output verification result.
The various embodiments described above only are used to illustrate the utility model; wherein the structure of each parts, connected mode etc. all can change to some extent; every equivalents of carrying out on the basis of technical solutions of the utility model and improvement all should not got rid of outside protection domain of the present utility model.
