Embodiment
As shown in Figure 1, the bending property testing device of electric car charger interface is equipped with one and charging gun to be detected
The cradle 2 to match, during detection, charging gun is inserted in cradle 2, and cradle 2 is inserted into the jack of charging gun downward, charging
The cable 6 of rifle is fixed with weights 4 close to one end of charging gun, and configuration counterweight generally uses 20N, increases the weight of charging gun
Amount, so as to detect the fastness that cradle 2 is combined with charging gun, the 20N that configuration regulation requires.It is cased with pressing from both sides outside cradle 2
Tool 5, fixture 5 are connected by the piston rod outer end of active connection and the cylinder of working in reciprocating mode 1, which is arranged on
The sliding slot of fixture 5, and the sliding block in sliding slot, the piston rod of cylinder 1 is outer to be connected with sliding block.
When cylinder 1 moves back and forth, charging gun radially wobbles with cradle 2, is detected work.Charging gun is band electrician
To make, lead to rated alternating current 10A, rated voltage 220V AC to cable 6, cradle 2 is equipped with input current sample circuit,
And the circuit of collection is delivered to controller, controller prints the current fluctuation situation of collection by printer, or by aobvious
Show that device is shown, so as to detect the charging quality in swing process.
As shown in Fig. 2, source of the gas 10 passes through three linked piece 9, air plankton and oiling are filtered.Go to three-position four-way electromagnetic directional valve
8, after solenoid valve KN is connected, source of the gas 10 leads to cylinder 1 by three-position four-way electromagnetic directional valve 8, stretches the piston rod of cylinder 1
Go out；After reaching n2 positions, battery valve KN power-off, source of the gas 10 is contracted the piston rod of cylinder 1 by three-position four-way electromagnetic directional valve 8
Return, can to control, cylinder 1 stretches out or retraction speed is at 60 beats/min with governor during this.This reciprocal working method, can
For carrying out the mechanical bend of charger interface.
To meet the weariness working mode of pneumatic device, circuit kit is needed to control whole system, as shown in figure 3, by outer
Portion's electricity cabinet is connected to the air switch in power supply box, and firewire connects fuse and connects whole circuit again.K1, K2 are relay, and KN is
8 solenoid switch of three-position four-way electromagnetic directional valve, plus an electronic counter 11.
A whole set of pneumatic action is all by n1, this 2 electromagnetic inductor controls of n2.After power on circuitry is connected, piston position
In n1, the coil KN energizations reversal valve of three-position four-way electromagnetic directional valve 8 is connected cylinder 1 and is stretched out after n1 is connected by magnetic；When piston arrives
When up to n2, n2 is connected cylinder 1 by the coil KN power-off reversal valves of magnetic three-position four-way electromagnetic directional valve 8 and retracted；It is whole to be retracted to n1
Set system starts the cycle over work.
When pressing switch key normal open switch, whole system power supply.When piston is in electromagnetic sensor n1 positions
N1 is connected, and K1 relay coils are powered, and all normal open switch of K1 are opened, and 3 position-5 way electromagnetic switch valve coil KN1 is powered, living
Stopper rod ventilation is pushed ahead.When piston to electromagnetic sensor n2 positions, n2 is connected, and K2 relay coils are powered, and the normally closed of K2 is opened
Pass disconnects at this time, and 8 coil blackout of K1 relays power-off KN three-position four-way electromagnetic directional valves, cylinder 1 is retracted.When 1 piston of cylinder returns
Onto n1 initial positions, circuit starts to perform working in reciprocating mode, and circuit starts reciprocation cycle work between n1 and n2 at this time.Herein
During, K2 relays are attracted once, and the normal open switch break-make primary electron counter 11 of K2 remembers a number, electronic counter 11
The counting of 5 digits is chosen, zero setting recycles again after counting 99999 times.
Based on the bending property testing device of above-mentioned electric car charger interface, tested using following methods,
Plug is fixed, in the weights 4 of 6 one load-carrying 20N of cable, leads to rated alternating current to cable 6
10A, rated voltage 220V AC
Cylinder 1 controls fixture 5 and charge gun swing angle more than 90 degree (preferably 90 degree)；
Number of oscillations is more than 20000 times, 60 beats/min of rate of bending；
2 charge data of cradle is read, if without powering-off state, charging gun is up-to-standard, if there are powering-off state, fills
Electric rifle is off quality.
If without circut breaking, and electric current without obvious fluctuation, then charging gun quality is outstanding.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements and from aforesaid way
Limitation, as long as the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress is employed, or without changing
