Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As shown in Figure 1 and Figure 2, a kind of FCT multistation of the present invention proving installation, comprise frame 1 and multiple single position test device for disposable test one piece of electric energy meter PCBA board, namely this single position test device is disposable can only test one piece of electric energy meter PCBA board; Described multiple single position test device is all arranged in frame 1.
Described single position test device comprise one piece for the pressure plate structure 2, that presses down electric energy meter PCBA board for the frock 4 that drives the actuator 3, of pressure plate structure 2 knee-action and place for electric energy meter PCBA board and one for providing the needle plate structure 5 of power supply and signal to electric energy meter, wherein actuator 3 is a cylinder, by it is connected can be normally worked with solenoid valve, source of the gas; Described actuator 3 is fixedly connected on the top of frame 1, and namely cylinder body is fixedly connected on the top of frame 1; The clutch end of described actuator 3 is connected with pressure plate structure 2, and namely the piston rod of cylinder is connected with pressure plate structure 2; Described frock 4 is slidably fitted on needle plate structure 5; Described needle plate structure 5 is located at the bottom of frame 1.
Described pressure plate structure 2 comprises fixed mount 2.1, first pressing plate 2.2 and second pressing plate 2.3; The clutch end of described actuator 3 is fixedly connected with the fixed head 2.4 on fixed mount 2.1, and namely the piston rod of cylinder is fixedly connected with the fixed head 2.4 on fixed mount 2.1; Described fixed mount 2.1 is provided with the two-layer step 2.5 supplying the first pressing plate 2.2 and the second pressing plate 2.3 to place respectively, and step is made up of left step 2.51 and right step 2.52, and described left step 2.51 and right step 2.52 are in same level; The first described pressing plate 2.2 is located on the step 2.5 on top; The second described pressing plate 2.3 is located on the step 2.5 of bottom; Described fixed head 2.4 is provided with multiple screw 2.6, and described screw 2.6 is connected on the first pressing plate 2.2 through fixed head 2.4, freely can be elevated the first pressing plate 2.2 by rotary screw 2.6; The first described pressing plate 2.2 has many pillars 2.7; Described many pillars 2.7 are against above the second pressing plate 2.3, freely can change the second pressing plate 2.3 by rising the first pressing plate 2.2; Be provided with multiple thimble 2.8 below the second described pressing plate 2.3, multiple thimble 2.8 pushes down electric energy meter PCBA board when pressure plate structure 2 declines, frock 4 declines.
