Embodiment
Below in conjunction with accompanying drawing 1-2, the embodiment of the technical solution of the utility model is described in further detail.
Embodiment: a kind of Ni-MH battery vent valve pressure testing machine, comprise frame 1, be provided with above frame 1 and detect platen 2, platen 2 is provided with operation bench 13, several pressure testing bodies 3(the present embodiment is two in detection) and movable draw runner 23, pressure testing body 3 is detected on platen 2 by being arranged on of movable draw runner 23 activity, and two pressure testing bodies 3 be arranged in parallel; Pressure testing body 3 is connected with and pushes cylinder 4, can according to the activity back and forth before and after the track promotion pressure testing body 3 of movable draw runner 23, pressure testing body 3 is provided with several (the present embodiment is eight) can place the first air release 5 detecting workpiece 7, each first air release 5 is independently connected with described digital display pressure switch 15, detect workpiece digital display pressure switch 15 in the process detected and show the pressure data accurately detected all the time in workpiece, effectively can improve the accuracy of reading.First air release 5 is provided with O-ring seal 8 with the junction detecting workpiece 7, effectively can prevent from testing process, gas leak phenomenon occurring at workpiece, affect testing result.Pressure testing body 3 is also provided with second air release 6 corresponding with the first air release 5, and the second air release 6 is corresponding with the first air release 5 quantity.
Second air release 6 is socketed with rapid-acting coupling 18, rapid-acting coupling 18 is socketed with snorkel 19, snorkel 19 is socketed on the second air release 6 of pressure testing body 3 by rapid-acting coupling 18, other one end of snorkel 19 is socketed with fast slotting threeway 20, snorkel 19 can be divided into three tunnels according to self three port by fast slotting threeway 20, fast the second end inserting threeway 20 connects digital display pressure switch 15 by snorkel 19, 3rd port is connected with solenoid valve 21 and pressurizer 22 in turn, pressurizer 22 delivers the gas to fast slotting threeway 20 by snorkel 19, by inserting threeway 20 soon, gas is delivered to digital display pressure switch 15 respectively with in detection workpiece 7 again, and digital display pressure switch 15 is identical with the air pressure detected in workpiece 7.
The top of pressure testing body 3 is also provided with pressing plate 9, pressing plate 9 is connected with compression cylinder 10, the two ends of pressing plate 9 are equipped with linear bearing 11, linear bearing 11 is socketed with slide bar 12, when detecting, compression cylinder 10 starts to promote the relation straight line that pressing plate 9 be socketed according to linear bearing 11 and slide bar 12 and compresses detecting workpiece 7 downwards, and prevent from leaking gas the detection be convenient to detection workpiece 7.
When detecting beginning, the detection workpiece 7 that first will detect is placed on the sealing gasket 8 of the first air release 5, prevent from leaking gas in testing process, start button 14 is pressed after placement, push the position (below of pressing plate 9) that pressure testing body 3 is recovered to restriction by cylinder 4, pressing plate 9, under the effect of compression cylinder 10, compresses downwards and detects workpiece 7.Meanwhile, solenoid valve 21 is opened, and pressurizer 22 is delivered the gas to by snorkel 19 and fast inserts threeway 20, delivers the gas to digital display pressure switch 15 respectively and detects in workpiece 7, and keep the air pressure between the two identical by inserting threeway 20 soon.When detecting the pressure in workpiece 7 and being increased to 0.091Mpa, constant voltage leaves standstill the several seconds (the present embodiment is 8 seconds), and the numerical value as digital display pressure switch 15 remains unchanged substantially, then Section 1 testing result is qualified.After obtaining testing result, continuation is pressurized to more than 0.15Mpa to detection workpiece 7 automatically, and the air release valve now detecting workpiece 7 can be opened, if the pressure shown by digital display pressure switch 15 sharply declines, then Section 2 testing result is qualified, otherwise is defective.After obtaining result, touch-screen 16 can show accurately the station of certified products and unacceptable product.Now compression cylinder 9 can upwards reclaim automatically, pushes cylinder 5 and pushes out by pressure testing body 3, divide certified products and unacceptable product by the fruiting area of staff according to touch-screen 16.Take out to detect after workpiece 7 and reappose the detection workpiece 7 do not detected, then press start button 14 cycle alternation and detect.
