Above-mentioned purpose of the present utility model is achieved through the following technical solutions:
For the bubble-tight test unit of solder joint in testing automobile wire harness, the top of casing 1 arranges air cavity fixture 2, and fixture upper cover 5 and described air cavity fixture 2 are rotationally connected; The two ends of casing 1 arrange rain glass 3 and master switch 7 respectively, and the side of casing 1 arranges pressure switch 4, and the side of casing 1 is supporting arranges tank 6; Described rain glass 3, to be connected by pipeline between pressure switch 4 and air cavity fixture 2; Described fixture upper cover 5 is made up of aluminium sheet and elastic pieces of foam, aluminium sheet can ensure the intensity of upper cover, and elastic pieces of foam is for ensureing the sealing of air cavity, the air pressure in air cavity fixture 2 is made to reach specific force value, air cavity is connected by the annular seal space of tracheae with hollow plastic material, and annular seal space directly processes in one piece plastics.
Described air cavity fixture 2, the quantity of pressure switch 4 are respectively at least one, by increasing or reduce air cavity fixture 2, pressure switch 4, the time relay and the corresponding quantity of pilot lamp, increase or reduce test sample quantity.By the setting of modification time relay and the equipment of pressure switch, different airtight testing conditions can be met.
Described casing 1 is airtight casing, and inside is fixedly installed the circuit board, the time relay and the solenoid valve that are electrically connected to each other, and the described time relay and pressure switch 4 are electrically connected.
The utility model provides gas to air cavity fixture 2 by source of the gas, air cavity fixture 2 is when sealing, and atmospheric pressure value rises, when atmospheric pressure value reaches particular requirement, pressure switch 4 exports an electric signal to the time relay, and the numerical monitor of self is become " redness " from " green ".And when time set by elapsed time relay, electric signal is given to pilot lamp by the time relay, namely when pilot lamp is bright, and when the numerical monitor in pressure switch 4 keeps " redness " always, namely meet specific testing requirements.
The beneficial effects of the utility model are:
1, amendment is convenient to
For ensureing the testing requirements of automobile main frame maker, in the time relay in device and pressure switch arrange can along with the testing requirements of main engine plants change time, carry out the testing requirements changing to realize main engine plants.
When the testing requirements of main engine plants increases, by increasing corresponding air cavity fixture, pneumatic switch, pressure switch, pilot lamp increase check point, and meet various testing requirements by arranging in the different time relays and pressure switch.
2, convenient mobile
Have employed aluminium sheet except on air cavity fixture, the outer whole casing material of electronic component, tensimeter is plastic member product entirely, and whole device is lighter, and tank is separated with casing, directly can lift movement.
3, make/amendment cost is low
Many accessories of device can be gathered materials on the spot, and what casing, air cavity fixture adopted is that the tailing making wire harness shelf is made, and tank forms with organic glass adhesion.Pressure switch, monotroded body rain glass, pilot lamp, the time relay need buying, and other parts such as tracheae, power lead can directly adopt spare part in factory.
4, easy to operate
Operator only needs opening power button, measured piece is put into air cavity fixture, closes fixture upper cover, rotates pneumatic switch and can start test.Observe that bubble-free is overflowed from tank, instruction when red, can judge stand the test.
