The utility model has effectively overcome the defective of existing capacitor testing machine, has following advantage:
1, electric capacity automatic test machine of the present utility model adopts the mechanical motion positioning principle, and electric capacity all is positioned at same position when testing at every turn, but when test the equal accurate in locating of electric capacity, each terminal is pressed when surveying the electric capacity pin and can not caused misjudgment because of dislocation.
2, electric capacity automatic test machine of the present utility model adopts guide rail component, guide rail can allow whole mechanical action more flexibly, more have to add long-time.
3. electric capacity automatic test machine of the present utility model, simple in structure, the convenient manufacturing is beneficial to popularization.
Description of drawings
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model frock plate.
Wherein: 1 guide rail; 2 frock plates retreat catching; 3 screw mandrels; 4 motion support plates; 5 frock plates; 6 location cylinders; 7 detents; 8 motion guide grooves.
Embodiment
Embodiment: as shown in Figure 1, a kind of electric capacity automatic test machine, the pressure that it includes frame, be used for testing capacitor is surveyed device, is used to place the frock plate 5 of testing capacitance.
Installing on motion support plate 4 of frock plate 5 activities, its with motion support plate 4 between can slide relatively, motion support plate 4 moves relative to frame, frock plate 5 is delivered to press survey setting position and sentence to make to press and survey device and press down its calibrating terminal to test.
Frame is provided with guide rail 1, and motion support plate 4 is installed on the guide rail 1, and can slide along guide rail 1.Frame is provided with screw mandrel 3, and screw mandrel 3 is connected with motion support plate 4, and may command motion support plate 4 moves.
Frame is provided with the frock plate and retreats catching 2.
As shown in Figure 2, frock plate 5 bottoms are provided with protuberance.The side of frock plate 5 protuberances is provided with motion guide groove 8.
As shown in Figure 2, also be provided with detent 7 on the frock plate 5.Frame is provided with the supporting locating piece of movable and detent 7, and in order to release the location cylinder 6 of locating piece.
Frock plate 5 is provided with the groove that is used to install the testing capacitance pin.In the time of can guaranteeing to test, its test position is all fixed at every turn, increases accuracy.
During use, the pincard of testing capacitance in the groove of frock plate 5, can be put two testing capacitances at every turn simultaneously, calibrating terminal is pressed when surveying, and each the pressure surveyed in frock plate 5 grooves.
Electric capacity on the intact frock plate 5 of every survey, screw mandrel 3 are pushed ahead a segment distance (being 100mm in the present embodiment).After frock plate 5 surpassed the frock plate and retreats catching 2 and put in place, screw mandrel 3 retreated and drives motion support plate 4 and retreat together, drives motion support plate 4 and retreats to the original position.
