Description
Technical field
The utility model belongs to automobile electronics detection technique field.Be specifically related to a kind of commercial car fuel-quantity transducer input fuel tank fuel quantity signal, the detection of output resistance function, to guarantee product input, the smoothness of output channel and the integrality of function.
Background technology
Along with the rapid popularization of electronic technology on automobile, and be core with microprocessor, realize controlling each Component Intelligentization of automobile, have the appearance of Electronic Control product that can be handling and maintainable, the equipment detected the performance condition of this electronic product matching used input pickup in the course of the work meets the tendency appearance.The functional check equipment being generally used for commercial car fuel-quantity transducer comprises power supply, industrial computer, servomotor controller, LCDs, manual fixture, manipulation keyboard, cable etc., corresponding simulating signal is selected according to product sensor parameter or function during inspection, manual operation manual clamping product sensor, tests to fuel-quantity transducer input, the smoothness of output channel and the integrality of function.There is following weak point in general utility functions inspection machine: one is that equipment for checking is more in disorder, and can not form an overall inspection equipment, floor area is large, also unfavorable checked operation; Two be use manual, affect detection efficiency, testing result is inaccurate by manual operation affects, and in checkout procedure as manual operation fixture will cause equipment or wiring board device impaired.
Summary of the invention
The purpose of this utility model is exactly the deficiency for general automobile oil mass sensor checkout equipment, and provide a kind of test speed fast, precision is high, can be applicable to the novel checkout equipment of commercial car fuel-quantity transducer produced in enormous quantities.
Technical solution of the present utility model is: a kind of commercial car fuel-quantity transducer function detection equipment, comprise power supply, PLC, servomotor controller, fixture, touch-screen, load, cable, it is characterized in that: the frame and the electric cabinet main body that also comprise one three layers; Touch-screen is loaded on the ground floor of frame; Power supply, PLC, servomotor controller are loaded in electric cabinet main body, and electric cabinet main body is loaded on the third layer of frame; Fixture is loaded on the second layer of frame; PLC is connected with power supply, servomotor controller, touch-screen, load, fixture by cable.
Fixture described in technical solution of the present utility model is the pneumatic type self-locking jig be made up of guide rail, sensor holder, clamping cylinder, start button, ball-screw, is provided with the probe coordinated with sensor inserted sheet to be measured in sensor holder; Probe is electrically connected with PLC.
Servomotor controller described in technical solution of the present utility model is programmable, intelligent module.
Fixture, owing to touch-screen to be loaded on the ground floor of frame, is loaded on the second layer of frame by the utility model, by power supply, PLC, is loaded in electric cabinet main body, be loaded on the third layer of frame, thus form all-in-one-piece fuel-quantity transducer function detection equipment, compact conformation, floor area is little, easy to operate.First product input parameter (stroke and resistance error scope) to be detected is arranged according to the needs of different product, then instruction is sent by serial ports to servomotor controller by equipment PLC, servomotor controller controls servomotor according to test procedure instruction and rotates, thus controls ball-screw movement travel.Leading screw displacement sends to sensor as test signal, and sensor output resistance feeds back signal to equipment PLC, by " order---feedback " mode comparison data, judges that whether sensor hardware function is normal.The utility model adopts pneumatic type self-locking jig, overcomes high, the inefficient shortcoming of manual operation technological requirement.The utility model due to adopt servomotor controller be programmable, intelligent module, thus PLC programming setting can be used according to required signal, reduce the complexity of apparatus of load cabinet on the one hand, reduce the volume of equipment, also improve the versatility of equipment and the flexibility ratio of upgrading on the other hand, as the sensor that detects change, only need to change control command, and need not hardware circuit be changed.The utility model overcomes the deficiency of general utility functions design of testing device, has that automaticity is high, device upgrade is convenient etc. a feature.The utility model is mainly used in commercial car fuel-quantity transducer and detects.
