Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Shown in Fig. 1-1,1-2,1-3, the pneumatic test fixture of a kind of ICT of the utility model, comprise cabinet and the following membrane module that is fixed on the cabinet, the described top of membrane module down is provided with upper die component, the big cylinder that is connected with upper die component also is installed on the described cabinet, described upper die component is provided with slide rail, and upper die component can slide up and down along slide rail.
As shown in Figure 2, extraneous gases at high pressure are drawn tracheae from solenoid valve 7 respectively then and are received on the air valve door 16 and stingy cylinder 6,8 of big cylinder 21 on being linked into solenoid valve 7 in the cabinet 1 by gas pipe line from the tracheae through hole on the cabinet backboard.Wherein big cylinder 21 is fixed on big cylinder 21 on the wall of computer case by big cylinder bottom plate 15; Big cylinder 21 upper ends are fixed on the protective cradle 29 by big cylinder upper mounted plate 28; Big cylinder 21 two ends are respectively air valve doors 16; The cylinder piston bearing 24 of big cylinder 21 is connected with an end of bearing interlock plate 25 by two hexagonal nuts 26, and the other end is connected with the upper end of connecting rod 23.Upper die component comprises patrix 17, upper mold holder 18 and upper mould fixed plate 20, and upper mould fixed plate 20 is fixed patrix 17 by upper mold holder 18, and patrix 17 moves up and down thereby the lower end of connecting rod 23 is connected drive with upper mould fixed plate 20; Upper mould fixed plate 20 is slidingly connected with slide rail 22 simultaneously, can orientation slide on slide rail 22, and leading ramp 22 makes patrix 17 remain level in the process of moving up and down; Following membrane module comprises cage plate 13, retainer plate 14 and counterdie 27, wherein retainer plate 14 be positioned at patrix 17 under, be cage plate 13 below the retainer plate 14, its contraposition and the counterdie under it 27 shield.Cage plate 13 lies on the counterdie 27, and counterdie 27 is fixed on the cabinet 1, and retainer plate 14 is connected with two stingy cylinders 6,8 by bolt, and stingy cylinder 6 and 8 is fixed in the cabinet 1 by stingy cylinder bottom plate 9,12 and stingy cylinder upper mounted plate 10,11.The work of two stingy cylinders 6,8 is by solenoid valve 7 controls. Circuit control system 2,3 as shown in Figure 2 is used for the opening and closing of control electromagnetic valve 7, and the duty of these two circuit control systems is by testing/finish button 4 and 5 controls of charging/material returned button simultaneously.The introducing of stingy cylinder 6,8 makes gets material safety when test is finished, when having avoided manually getting material by the material mode of getting of air cylinder driven to the damage of FPC; The introducing of cylinder 21 makes that test pressure is even in the testing engineering, has improved the reliability of test.
