Background technology
In manual, the automatic gear blocked operation of existing automobile; Need a kind of specially designed electromagnet; Be used for locking to the motor car engine gear; The function of this product is between the automobile gear switch, to play locking action, has only when automobile and is stepping on clutch coupling or the gear shift button pressed on the automatic transmission gear shifting handle could be accomplished gear shift, prevents the fault danger that brings owing to maloperation.Usually the production test to this electromagnet all is to lean on manually to accomplish, and wastes time and energy very much.Because the needs in the design, when stroke required height and the suction-combining force more small, artificial test can become and can not realize when this electromagnet.
Summary of the invention
The purpose of this invention is to provide a kind of automobile gear switch locking electromagnet parametric synthesis tester.
Technical scheme of the present invention is that a kind of automobile gear switch locking electromagnet parametric synthesis tester comprises microcontroller, display interface and display; Also comprise a pneumatic test fixture, tested electromagnet places in this pneumatic test fixture, behind the double-button device of pressing tester; This pneumatic test fixture moves under the control of microcontroller and approaches to predeterminated position; Contact with the power supply motor until tested electromagnet, make tested electromagnet be in power-up state
The pneumatic test fixture of microprocessor controls driven by servomotor moves to force transducer on a slide rail; Make tested electromagnet roof pressure to this force transducer; Servomotor is with the direction progressive motion to the roof pressure force transducer of 0.5 millimeter spacing, and laser displacement sensor constantly detects the shift length of tested electromagnet, and microcontroller is noted the numerical value of the force transducer of each displacement interval; Cover 5 millimeters stroke until servomotor
Microcontroller also writes down maximum running current, coil resistance and the actuation time of tested electromagnet simultaneously.
The present invention has realized the robotization integration test of automobile gear switch locking electromagnet parameter.
Description of drawings
Fig. 1 is that the system of tester of the present invention forms synoptic diagram.
Embodiment
As shown in Figure 1, automobile gear switch locking electromagnet parametric synthesis tester of the present invention comprises microcontroller, display interface and display; Also comprise a pneumatic test fixture, tested electromagnet places in this pneumatic test fixture, behind the double-button device of pressing tester; This pneumatic test fixture moves under the control of microcontroller and approaches to predeterminated position; Contact with the power supply motor until tested electromagnet, make tested electromagnet be in power-up state
The pneumatic test fixture of microprocessor controls driven by servomotor moves to force transducer on a slide rail; Make tested electromagnet roof pressure to this force transducer; Servomotor is with the direction progressive motion to the roof pressure force transducer of 0.5 millimeter spacing, and laser displacement sensor constantly detects the shift length of tested electromagnet, and microcontroller is noted the numerical value of the force transducer of each displacement interval; Cover 5 millimeters stroke until servomotor
Microcontroller also writes down maximum running current, coil resistance and the actuation time of tested electromagnet simultaneously.
In the practice, tester system specifically can adopt with lower component:
● the main hardware that this test macro is used: the test board of C8051F005 single-chip microcomputer independent research; Adopt the host computer test board of Samsung 2440 based on the WINCE platform; The KEYENCE laser displacement sensor; The force transducer of the 0-100g range of specialty customization, Korea S MGN15CC spherical guide, Panasonic's servomotor;
● this system is used for the maximum running current of HG4844 electromagnet, stroke, actuation time, suction, coil resistance test;
● the test parameter bound can be set, and the result shows and the hummer indication with liquid crystal display, pilot lamp;
● method of testing is divided into: accurately test; Walk through test; And the zero correction of motor; Can oneself select, accurately test be from electromagnet 1MM stroke to this interval of 5MM stroke in every 0.5MM carry out the test of power size for one grade, walk through test is single size of surveying the power at 1MM stroke and 5MM stroke place; These two kinds of method of testings can be used for parameter index such as the Linearity of analytic product performance, power or be used for the production line test.
The test philosophy explanation of above-mentioned tester as follows.
Special test fixture is put in the product contraposition, product is powered on, electromagnet is inhaled moving, and system adopts the up-to-date laser displacement sensor of KEYENCE to come product displacement to test.The displacement of obtaining product is as stroke.And the judgement of actuation time; Same sampling laser displacement sensor is judged; This electromagnet inside has padded coaming to play a protective role; Produce when product has certain damped vibration from power on after the action of range, and to the judgement of product actuation time be with product power on to take place range and stable after think actuation time, therefore; The variation of the displacement sampled value through laser displacement sensor judges whether the electromagnet action is stable, and single-chip microcomputer then calculates actuation time through the output valve of sensor.
To the part of detecting of product suction, require gradual sampling, the mode that therefore adopts Panasonic's servomotor to combine with force transducer is come; Starter motor makes the product of having inhaled slowly slide to force transducer, when single-chip microcomputer sample force transducer when changing (the expression product contacts with force transducer) stop servomotor work; And then from then on rise the position; Starter motor is at interval progressive motion with 0.5MM, and single-chip microcomputer cooperates sampling force transducer output valve, stops during to 5MM up to stroke; Break off the product power supply, motor is got back to initial position.
The test of running current and coil resistance then is to power on initially at product, measures with accurate sample resistance and constant current source.
This tester for the product test method of HG4844 electromagnet is:
1. the socket that plugs in is opened power supply; Turn on the power switch, open air valve;
2. open WINCE operating system, get into the wolf2440 dish, double-click < 4844 electromagnet integration test >;
3. click the parameter setting, the test parameter of check and correction corresponding product by preserving, again by reading, minimizes this window again;
4. on main interface, test interface appears in the some operation, the some beginning;
5. at test interface, point begins test
6. with the product anchor clamps of correctly packing into;
7. both hands are pressed the startup button, begin to test;
If qualified products, data presentation, bright qualified lamp, three weak points of hummer; If defective, data presentation, the lamp that do not work, hummer one is long;
8. the taking-up product like the need follow-on test, repeats above step 6-7 and gets final product;
9. as changing the product test of another kind of model, at first close test interface, from the small icon of the lower right corner, point out parameter the interface is set, and close; Get back to program head interface, be provided with in parameter and choose model and the test mode of wanting test products corresponding in the combobox, the check and correction test parameter is set in the interface in the parameter that ejects; And put and preserve and read, minimizing this window then, the mid point operation at first interface is in test interface; The point beginning by starting button, just can begin to have tested then.
