The sequence of the mechanical action of whole device:
1: doing the electrostatic experiment of electric appliance in 27 side of experimental bench, when testing the working condition of electric appliance, electric appliance is placed on conductive flat
On platform 16, electrical work passes through the automatic earthing of experimental bench, test record electrical work data；
2: when needing to test working condition of the electric appliance in earth-free and energization, motor 8 works, to make drive shaft 7
Rotation, so that the first belt pulley 6 be made to rotate with cam 11, the rotation of cam 11 moves sliding panel 4 backward, and torsionspring 10 is turned round
Turn, so that trapezoid block 3 be made to move backward, so that clamping plate 25 be made to lose limitation, connecting spring 59 resets two pieces for driving and connecting
Clamping plate is close to each other, so that sliding shoe be driven to return in ejection chamber 26, so that translation plates 58 be made to move, sliding spring 51 is pressed
Contracting, so that the supporting block 18 be made to leave restricted room, simultaneously because the movement backward of the sliding panel 4, thus make rack gear 42 to
After move, thus make rotate gear 40 rotate, to make Slave Block 37 travel forward, so that rope 38 is pulled, to make spring
Plate 46 moves downward, to make conducting block 14 move downward, so that leaving the conducting block 14 in left side connects electric chamber 22；
The rotation of 3: the first belt pulleys 6 drives the rotation of the second belt pulley 31 by the transmission of belt 9, to make 30 turns of driven shaft
Dynamic, when cam 11 rotates, spill spin block 33 is rotated, when cam 11 receives rotation 28 lower end wall of chamber limitation and is not able to rotate, spill spin block
33 limitations for receiving 58 end wall of mobile cavity are not able to rotate, and motor 8 works at this time, so that driven shaft 30 is continued to rotate, from
And move right mobile bar 15, so that conductive platform 16 be made to move right, by the transmission of cord 29 drive clamping plate 25 to
Left movement, to drive fixed link 24 to move downward, to make insulated platform 19 move downward, to the right due to conductive platform 16
Movement and insulated platform 19 moves downward, so that insulated platform 19 be made to move downward while moving downward, lifting spring
20 compressions, after conductive platform 16 moves right right end completely into right side rotation chamber 28,19 left end of insulated platform enters
Left pivot movement chamber 28, lifting spring 20, which resets, at this time drives insulated platform 19 to rise, and two platforms are mutually organized and made on two platforms
End face is in same horizontal line, and then motor 8 stops working, and two platforms complete location swap；
4: during conductive platform 16 moves right, 47 upper end of left side friction block and 28 upper end wall friction of left pivot movement chamber, from
And just moved right after friction block 47 is contacted with 13 left end wall of left side spring groove during moving right conductive platform 16,
The closing of the limit plate 48 left side spring groove 13 in left side at this time, when 16 right end of conductive platform enters in right side rotation chamber 28, right side
Friction block 47 and right side rotate 28 upper end wall friction of chamber, when right side friction block 47 and 13 left end wall of right side spring groove contact Shi Caixiang
Right movement, until 16 stop motion of conductive platform, right side spring groove 13 connect electric chamber 22 with right side and be connected to；
5: when insulated platform 19 is located at left side, the front end of the two pieces of trapezoid blocks 3 in left side is located between two pieces of clamping plates 25；
6: motor 8 stops working, so that drive shaft 7 stops working, torsionspring 10 resets at this time, and band moving cam 11 resets, from
And sliding panel 4 is made to travel forward under the drive of reset spring 32, to make trapezoid block 3 travel forward, to make clamping plate 25
It is separated with sliding shoe 53, so that translation plates 52 be made to reset under the action of sliding spring 51, supporting block 18 reenters limit chamber
17 interior and supports insulative platforms 19, guarantee the stabilization of insulated platform 19；
7: the hour rack 42 that travels forward of sliding panel 4 resets under the action of compressed spring 41, thus make to rotate gear 40 with it is driven
Block 37 resets, so that rope 38 be made to become loose, the right side latch plate 46 is moved upwards with conducting block 14, and right side conductive block 14
Upper end enters right side and connects in electric chamber 22 and connect with link block 23, the automatic earthing of completion conductive platform 16, and left side conducting block
14 cannot rise due to the limitation of left side limit plate 48；
8: after the location swap for completing two pieces of platforms, electric appliance being placed on insulated platform and does electrostatic experiment again, and is no longer connect
Ground obtains test data, completes comparison.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow be familiar with this field technology
Personage can understand the content of present invention and be implemented, and it is not intended to limit the scope of the present invention.It is all according to the present invention
