Described stand 5 is respectively equipped with: electrical control unit 11, pneumatic control unit 13, reduction valve 14, tensimeter 15, pressure switch 16, Switching Power Supply 17, fixture air inlet stop valve 18, fixture discharge line valve 19, electrical control unit 11 are connected with tensimeter 15 with starting switch 12, pneumatic control unit 13 respectively by wire, pneumatic control unit 13 is connected with piston pushing mechanism 3 respectively by gas circuit, and pressure switch 16 is connected with pneumatic control unit 13 with electrical control unit 11.
Built-up jig in the present invention: built-up jig air intake opening 10 hydraulic quick coupler makes replacing product quick and convenient, and this fixture product has: PT000 is serial, PT100 is serial, PR181 is serial, PR159 is serial, 5T01 is serial.This fixture can reach 5-6 to the sealing surface of workpiece, so the right side adopts in fixture: right side sealing detent mechanism 24, adopt below: lower side seals connects detent mechanism 25, adopt above: sealing clamp 23 above, the right side adopts: left side sealing clamp 21.Middle for not interfering other location so adopt: intermediate seal fixture 22, make fixture operation convenient like this, cost of manufacture is low.
The liquid that leaks hunting in the present invention: because the material major part of high-speed transplanter box parts is ironcasting, be very easy to get rusty, so the requirement to the liquid that leaks hunting: one is antirust, two liquid are as clear as crystal, and three want garbage energy automatically to precipitate.What in the liquid that leaks hunting in the present invention, solvent adopted in industrial pure water tap water is chloride too high, and solute adopts semi-synthetic cuttings liquid, with the percentage by weight proportioning of 5%.Making to leak hunting, liquid is as clear as crystal, the automatic sedimentation function of rubbish is good, rust-preventing characteristic well generally can keep a week.
Feature of the present invention: detect data admission pressures, continue air pressure, the dwell time presets, freely, result understands fast in operation, and test is correct, mistake proofing front, detection means science.
principle of work
1 operation prepares:
Open source of the gas, inspection measuring pressure≤5.5kg/cm2, closes built-up jig gas admittance valve, opens built-up jig vent valve, opening power, arrange the dwell time.
2 methods of operating
To detect a certain part of high-speed transplanter casing, the lower side seals be placed on by measured piece on built-up jig 7 connects on detent mechanism 25, and sealing connects on detent mechanism 24 on the right side of being close to the right, operation left side sealed clamping structure 21, be that it clamps left, operate sealed clamping structure 23 above simultaneously, compress downwards, operation intermediate seal clamp system 22, seals the side leakage mouth of centre.Close built-up jig vent valve 18, open built-up jig gas admittance valve 19, if simultaneously pressure switch 16 starts to detect air pressure "Yes" "No" in built-up jig automatically arranging arrange in scope just can starting switch 12 in scope, if just do not started arranging starting switch 12 in scope.Starting switch 12, warning lamp 1 glimmers, electrical control unit 12 works, dwell time starts timing, pneumatic control unit 13 works, piston pushing mechanism 3 is started working, promotion built-up jig moves downward, and is that its built-up jig 7 is immersed in together with workpiece and leaks hunting in liquid, the leak condition of observation period workpiece, after dwell time arrives, electrical control unit 11 controls pneumatic control unit 13, makes piston pushing mechanism 3 drive built-up jig 7 to move upward, and arrives the position of clamping, pull down workpiece, whole airtight test procedure terminates.
