Description
Technical field
The utility model relates to pressure unit automatic lot detector, belongs to product detection technique field.
Background technology
At present, pressure unit dispatches from the factory or enters after factory, all needs to detect its performance, detects rules in conjunction with it, and the pressure of pressure unit is had to a process that detects the check of differentiation to characteristics such as the translation function of electric signal, stability, consistance.
At present, tradition is existing is mainly to adopt single-point, single pressure unit to detect to the detection of pressure unit, and the detection of transmitter all needs manual intervention just can complete, detecting data needs manually record or manual entry computer, wastes time and energy, work efficiency is lower, human cost is high, can not carry out fast, detect in bulk, and the trackability that detects data is poor, and easily introduce personal error and cause data distortion, the accuracy and the reliability that detect data are poor.
Utility model content
The purpose of this utility model is to provide a kind of pressure unit automatic lot detector that can overcome above-mentioned technical matters, to realize the automatic batch detection of pressure unit.
The utility model comprises: PC main frame, printer, slave computer controller, scanning switch, RS232 serial ports, full servo pressure control system, tested frock 1, tested frock 2, tested frock 3, standard pressure transducer; Described slave computer controller is single chip machine controlling circuit, described slave computer controller for realizing loop-around data collection to scanning switch, show, upload and the function such as control to full servo-control system.Described full servo pressure control system comprises: the speed reduction unit, fixed guide mechanism, pressurization oil cylinder, servomotor, oil filling pump, manual oil filling pump, fuel tank, solenoid valve and the stop valve that link together.
Described printer, PC main frame, RS232 serial ports, slave computer controller, scanning switch connect successively; Described full servo pressure control system is connected with slave computer controller; Described full servo pressure control system is connected with tested frock 1, tested frock 2, tested frock 3, standard pressure transducer respectively; Described scanning switch is connected with tested frock 1, tested frock 2, tested frock 3 respectively; Described slave computer controller is connected with standard pressure transducer.
It is for reaching accurate pressure controling precision that the utility model adopts described full servo pressure control system, to guarantee that pressure controling precision and degree of stability are all in 5/10000ths scopes, in pressure control procedure, slave computer controller is followed according to current pressure value and setup pressure value, send corresponding control wave and control described full servo pressure control system, pass through speed reduction unit, again by fixed guide mechanism, power is conducted to pressurization oil cylinder, by the pressure of pressurization oil cylinder control capstan, under original state, by oil filling pump, the oil in fuel tank is charged to capstan, so that servomotor is controlled pressure fast.
Basic functional principle of the present utility model is: be arranged on the tested frock station of pressure by standard pressure transducer and by tested pressure unit, by the control panel of standard pressure transducer cable connection, pressure unit connecting line is connected to the respective channel of scanning switch.When work, PC main frame is connected with slave computer controller by RS232 serial ports, after successful connection, the spot pressure that PC host setting pressure unit need to detect, detect the number of strokes, and successively the spot pressure that will detect of previously having set is sent to slave computer controller, when the next machine controller receives after order, start to start and make compression functions, the tested frock pressure of pipeline is reached and be stabilized in 5/10000ths accuracy rating of setting value, when continous-stable Time Continuous reached after 5 seconds, slave computer controller circle collection single pass switch, respectively the electrical signal data collecting uploaded to PC main frame and carry out record by PC main frame, when PC main frame receives after end of transmission (EOT) request, carry out next check point, down carry out successively, until reach the detection number of strokes of setting.
The utility model has the advantages that the detection efficiency that has greatly improved the pressure unit in production application, greatly save manpower and materials and reduced production cost, make to make pressure, detection and examining report and realize automatic integratedization, manual intervention and personal error are reduced, the accuracy and the reliability that detect data are improved, the trackability that has improved detection efficiency and detection data, the utility model stable work in work, has stronger practical value and realistic meaning.
