The two ends of described driver plate have one group of sprocket wheel and trapezoidal screw respectively.
The flexible glue confining force of described upper bolster mechanism.
Good effect of the present utility model is: stepper motor makes sprocket rotation, sprocket rotation transmission trapezoidal screw, trapezoidal screw is located driver plate, make on the driver plate patrix of upper clamping plate implement desired pressure, come the voltage endurance capability of test plug or mobile jack, test specimen connects low-voltage dc power supply, connects pilot lamp and judges whether plug or mobile jack damage, and this signal is sent to PLC simultaneously to end the applied voltage test of equipment.Adopt step motor drive, equipment is steadily pressurizeed to product.The pressure that counterdie bears is passed to pressure transducer by the counterdie seat board, and signal is transferred to stepper motor, again by step motor control patrix applied pressure size and retention time
The utility model adopts two guide pillar mariages structures, equipment uniform force application, balance.Adopt motor-driven, steadily pressurize, need not source of the gas.Upper bolster adopts elastic gum confining force mechanism, can guarantee that the dwell time internal pressure is stable.Patrix can have at a high speed, two kinds of test models of low speed, and the dwell time can be set, and the test pressure setting range is wide.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is that the A of the utility model embodiment is to the structure for amplifying synoptic diagram;
Fig. 3 is that the B of the utility model embodiment is to the structure for amplifying synoptic diagram.
Wherein: 1-patrix, 2-counterdie, 3-upper clamping plate, 4-counterdie seat board, 5-column, 6-driver plate, 7-trapezoidal screw, 8-pressure transducer, 9-frame, 10-sprocket wheel, 11-stepper motor.
Embodiment
Describe the utility model by the following examples, should be noted that, cited embodiment should not understand the restriction to utility model.
As shown in the figure: a kind of compression test device of present embodiment comprises frame 9, stepper motor 11 and pressure transducer 8 are installed in the frame 9, stepper motor 11 is connected with sprocket wheel 10, sprocket wheel 10 is connected with trapezoidal screw 7, and trapezoidal screw 7 is connected with driver plate 6, and upper clamping plate 4 is installed on the driver plate 6, patrix 1 is installed on the upper clamping plate 4, counterdie seat board 4 is installed on the pressure transducer 8, counterdie 2 is installed on the counterdie seat board 4, trapezoidal screw 7 is installed in the column 5.Driver plate 6 makes patrix have 10 mm/min (at a high speed), two kinds of speed of 5 mm/min (low speed) by stepper motor 11 controls.
When the utility model uses, earlier instrument is plugged in, indicating devices such as control panel, tensimeter, warning, station warning indication are arranged in the frame front, also have power supply, startup, emergency stop switch device.Set test pressure.Sample is installed on the anchor clamps.Enter the operation interface of corresponding modes, set test parameters (zero clearing number of times).By manual decline button, drop to the appropriate location.Press start button, equipment enters test job.Finish equipment auto stop behind the test number, take off sample evaluation.
Concrete is operating as: connect instrument power source, turn on the power switch, earlier patrix is lifted away from counterdie on manually one segment distance is arranged by manual rising, again with the circuit of the plug of required detection or its parcel of mobile jack or pick out circuit one and be terminated in the station wiring, instrument has 5 station wiring and 5 stations warning indications, can test simultaneously for 5 samples.During wiring, each plug or mobile jack are by the circuit of its parcel or pick out circuit and be connected to the station wiring one by one, and each station wiring has three connection terminals respectively.Connect the line, plug or mobile jack are placed on the counterdie.On tensimeter, set test pressure 150N earlier.In the control panel panel, select dynamic test, patrix descends with the speed of 5 mm/min of setting, when touching the plug that is put on the counterdie or mobile jack, pressure can be increased to the 150N of setting, because pressure transducer is transferred to the signal of stepper motor certain hysteresis is arranged, stepper motor drives patrix and can surpass 150N just for the pressure of plug or mobile jack, after receiving that pressure transducer is transferred to the stepper motor signal, stepper motor drives the speed rising of patrix with 10 mm/min of setting immediately, then in persistent pressure slowly, up to the 150N that is stabilized in setting, and keep required setting-up time.In 10.1st clause of GB2099.1-1996, require to be pressed between two flat planes to reach 5 minutes about the electrocution-proof protection test of plug or mobile jack; after the off-test 15 minutes, the distortion of sample must not make the related standards defined, change in order to guarantee safe those over-dimension ground.When sample damages, plug or mobile jack will be detected by the circuit of its parcel or the dc signal that picks out in the circuit, make the bright and generation alarm sound of station alarm lamp.Can make the end of reporting to the police by the emergency stop switch device, last molding pressure is eliminated.The test that requires in corresponding the 24.5th clause of GB2099.1-1996 about physical strength can be made as 300N with test pressure, and the retention time was made as 1 minute, and test findings can be detected by the dc signal of circuit equally.
In this technical scheme, comprise two kinds of test models: dynamic test and static test.Dynamic test can make sample be subjected to pressure pressure to reach predefined value and keep this value up to end of test (EOT) automatically by automatic pressurization, finishes afterwards pressure and eliminates automatically.Static test is the replacement scheme of dynamic test, can reach needed force value by manual rising of manual control and manual decline button, after the retention time finishes, need manually rise and eliminate institute's applied pressure.
When the utility model is made, process each parts and assembling by above-mentioned requirements.Technical scheme described in the utility model is not restricted in the scope of embodiment described in the utility model.The utility model not technology contents of detailed description is known technology, and the variation that the those of ordinary skill in relevant technologies field is made in the corresponding techniques field according to the utility model should belong to protection category of the present utility model.
