Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
This Airtight vacuum detector comprises worktable 1, and worktable 1 is provided with lower bolster 17, and lower bolster 17 is provided with the counterdie 6 of finding time of being with the gas port 18 of finding time, and gas port 18 places of finding time are provided with O-ring seal 19.Lower bolster 17 tops are supported with cope match-plate pattern 3 by column 4, this cope match-plate pattern 3 is provided with the seaming chuck 5 that can cover the gas port 18 of finding time, this seaming chuck 5 is to slide up and down with cope match-plate pattern 3 and cooperates, and seaming chuck 5 both sides are provided with balance stem 8, and this balance stem 8 is with cope match-plate pattern 3 and is slidingly matched.Be connected with on the seaming chuck 5 and drive its drive unit that slides up and down; Drive unit comprises source of the gas 13, cylinder 9, is provided with the air filter between source of the gas 13 and the cylinder 9 and passes device variable valve 14, reversal valve KA 1, the piston rod of cylinder 9 and seaming chuck 5 are affixed.Find time to be connected with on the counterdie 6 and vacuumize assembly, and is connected with tested workpiece, vacuumize assembly and comprise vacuum pump 11, be connected with vacuum on this vacuum pump 11 in turn and filter biography device variable valve 12, stop valve KA by connecting flexible pipe 7 2, KA 3, stop valve KA 2, KA 3Between a stop valve KA in parallel 4, this output terminal that vacuumizes assembly is provided with A interface 15 that is connected with digital display meter 2 and the B interface 16 that is connected with tested workpiece.Also be provided with tensimeter 10 on the worktable 1.
Among Fig. 4, D is a vacuum pump, P 1, P 2It is the tensimeter relay.Button: SB, SB 1, SB 2(LAY37).A.C. contactor J (LC1D12).Auxiliary reclay J 1(JTX-3C).Time relay sj 1, SJ 2, SJ 3, SJ 4, SJ 5(ST3PA-B).Signal lamp (AD11-25/40-1G).
According to Fig. 1, Fig. 2, Fig. 3, Fig. 4, the principle of work of this detector is: opening power, press start button SB, and contactor J adhesive, vacuum pump D starts working.The pneumatics power of taking seriously reaches on the setting value prescribes a time limit, and pressure switch P1 disconnects, contactor J dead electricity, and vacuum pump D stops; The pneumatics power of taking seriously is worked in setting range.Its course of action is: when detecting workpiece, at first press and detect start button SB 2, KA 1Energising → cylinder 9 presses down → seals the gas port 18 → KA that finds time 2, KA 3(the time-delay) → KA that bleeds switches on 2, KA 3Outage (time-delay) → KA 4Beginning is measured in energising, measures bright (the time-delay) → KA of lamp 3Energising venting (time-delay) → testing result.
Measure lamp and observe PT401 digital display meter 2 readings when bright, if it stablizes constantly in Measuring Time for setting pressure, then its vacuum-tightness is good, meets the requirements.If in Measuring Time, its pressure value descends, and illustrates that then its sealing is relatively poor, and product is defective.In addition, each delay time is according to the technological requirement scalable.
