Fig. 2 is the one-piece construction front view of the utility model;
Fig. 3 is the control principle figure of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Referring to Fig. 1, Fig. 2, Fig. 3; The electric iron wire harness tracheae air tightness test device of the utility model; Comprise box body 1; In box body 1, be provided with PLC16, single-chip microcomputer 17, air inlet solenoid valve 12 and pressure transducer 15, on box body 1, be provided with the charging connector 11 that is used for external source of the gas, and be used for and the first inflation anchor clamps 13 and the second inflation anchor clamps 14 of treating that eudiometer 2 is connected.The first inflation anchor clamps 13 connect with air inlet solenoid valve 12; Air inlet solenoid valve 12 connects with charging connector 11; The second inflation anchor clamps 14 connect with pressure transducer 15; Pressure transducer 15 links to each other with the PLC16 electric signal, and PLC16 also links to each other with single-chip microcomputer 17 two-way communications and links to each other with the second inflation anchor clamps, 14 electric signal with the first inflation anchor clamps 13.
In the utility model the first inflation anchor clamps 13 and the second inflation anchor clamps 14 are air-actuated jaw, by PLC16 its locking of control or release.
The principle of work of the utility model can combine Fig. 1, Fig. 3 to explain as follows: when certain electric iron wire harness tracheae of needs test; This electric iron wire harness tracheae 2 is connected between the first inflation anchor clamps 13 and the second inflation anchor clamps 14, and two inflation anchor clamps are automatically with tracheae 2 lockings.Press the start key on the lower device 1; Signal air inlet solenoid valve 12 is sent in the PLC16 operation, and external source of the gas is got into by charging connector 11; Give tracheae 2 inflations through reduction valve (not shown), air inlet solenoid valve 12 and inflation anchor clamps 13,14, and charge pressure is transferred to pressure transducer 15.After being charged to certain air pressure, pressure transducer 15 feeds back signal to PLC16, and PLC16 sends and closes the gas admittance valve signal, stops inflation, and keeps a period of time.Pressure transducer 15 receives the air pressure in the tracheae 2, amplifies pressure signal, and through high speed MCU collection and deal with data, built-in sophisticated sensor carries out pressure compensation, judges the leak case of tracheae 2.If tracheae 2 has do not reveal, pressure transducer 15 will send electronegative potential and give PLC16, behind the PLC16 acknowledge(ment) signal, send electronegative potential again and will start single-chip microcomputer 17, and single-chip microcomputer 17 is started working, the test wire harness.After the wire harness test passes, the qualified signal of single-chip microcomputer 17 feedbacks is given PLC16, and PLC16 sends signal controlling inflation anchor clamps 13,14 and discharges automatically, and tracheae 2 can take out from anchor clamps, judges that tracheae is qualified.As little pore is arranged on the tracheae 2, charge pressure numerical value can't rise, and pressure transducer 15 will feed back noble potential and give PLC16; After PLC16 accepts noble potential, output alarm signal immediately, single-chip microcomputer 17 can't accept enabling signal; Quit work, this moment, PLC16 judged that tracheae is defective.
