Utility model content
The technical problems to be solved in the utility model there is provided a kind of air tightness detection machine improving joint air-leakage test efficiency.
The technical solution of the utility model is as follows:
A kind of joint air tightness detection machine, comprise worktable, vertically supporting seat is provided with at the upper face of described worktable top board, cylinder is provided with in the side of described supporting seat, described cylinder is provided with fixed block, described fixed block is installed with jaw cylinder, the lower end of described jaw cylinder is provided with jaw, immediately below described jaw correspondence position top board on be provided with a through hole, the lower surface of described worktable top board is to the position of through hole being installed with parallel bars cylinder, the output terminal of this pair of bar cylinder is provided with the inflation bar protruded upward, described inflation bar is upwards fed through this through hole, also be provided with gas filling valve and three-dimensional joint in the side of described worktable top board upper face, described gas filling valve and three-dimensional joint first to connection, described inflation bar and three-dimensional joint second to connection, the three-dimensional of described three-dimensional joint is provided with pressure transducer, the lower end of described worktable is installed with pressurized cylinder, the output terminal of this booster jar by tracheae successively with gas filling valve, three-dimensional joint with inflate bar and be communicated with.
Adopt above structure, when starting airtight detection, booster jar provides the pressure-air of pressure stability to gas filling valve, cylinder on supporting seat stretches out downwards, and the jaw of jaw cylinder lower end is clamped, two bar cylinders simultaneously below base plate drive inflation bar to protrude upward, and the insertion of inflation bar has been installed in the joint of O-ring seal, at this moment, gas filling valve is opened, gas is through three-dimensional joint, inflation bar is constantly inflated in joint, when the pressure remained steady that pressure transducer detects, gas filling valve is closed immediately, now, gas filling valve is closed to the whole loop of joint, pressure transducer starts the pressure detection of carrying out the default time, and the pressure after original pressure during pressure stability and detection being terminated is sent to control system by electric signal, whether the impermeability that control system detects analysis to measure by program is qualified, structure is simple, easy to use, cost is lower simultaneously, applied widely.
In order to make charge pressure even, as preferably, the outside of described inflation bar upper end is provided with two ventholes.
In order to avoid damage O-ring seal when inflation bar stretches into joint, as preferably, the edge in described inflation masthead portion is provided with fillet, and radius of corner is 5mm.
Beneficial effect: the utility model utilizes inflation bar to stretch into joint, makes the cavity forming relative closure in joint, then carry out air-leakage test by inflation bar inflating pressure, structure is simple, easy to use, and cost is lower, applied widely simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of inflation bar.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, the utility model is made up of worktable 1 etc., supporting seat 2 is vertically provided with at the upper face of described worktable 1 top board, cylinder 3 is provided with in the side of described supporting seat 2, described cylinder 3 is provided with fixed block 31, described fixed block 31 is installed with jaw cylinder 4, and the lower end of described jaw cylinder 4 is provided with jaw 41.
Immediately below described jaw 41 correspondence position top board on be provided with a through hole, the lower face of described worktable 1 top board is to the position of through hole being installed with parallel bars cylinder 7, the output terminal of this pair of bar cylinder 7 is provided with the inflation bar 71 protruded upward, described inflation bar 71 is upwards fed through this through hole, the outside of described inflation bar 71 upper end is provided with two ventholes 72, and the front edge of this inflation bar 71 is provided with the fillet that radius is 5mm.
Gas filling valve 5 and three-dimensional joint 6 is also provided with in the side of described worktable 1 top board upper face, described gas filling valve 5 and three-dimensional joint 6 first to connection, described inflation bar 71 and three-dimensional joint 6 second to connection, the three-dimensional of described three-dimensional joint 6 is provided with pressure transducer 9; The lower end of described worktable 1 is installed with pressurized cylinder 8, the output terminal of this booster jar 8 by tracheae successively with gas filling valve 5, three-dimensional joint 6 with inflate bar 71 and be communicated with.
Using method of the present utility model is as follows:
As depicted in figs. 1 and 2, when starting airtight detection, booster jar 8 provides the pressure-air of pressure stability to gas filling valve 5, cylinder 3 on supporting seat 2 promotes fixed block 31 and stretches out downwards, and make the jaw 41 of jaw cylinder 4 lower end clamp (sign), two bar cylinders 7 of worktable 1 top board lower face drive inflation bar 71 to protrude upward simultaneously, and inflation bar 71 is inserted install in the joint of O-ring seal, at this moment, gas filling valve 5 is opened, gas is through three-dimensional joint 6, inflation bar 71 is constantly inflated in joint, when the pressure remained steady that pressure transducer 9 detects, gas filling valve 5 is closed immediately, now, gas filling valve 5 is closed to the whole loop of joint, pressure transducer 9 detects an original pressure, simultaneity factor starts to carry out pressure detection, when reaching detection time, pressure transducer 9 detects that is terminated a pressure, and by the original pressure detected with terminate pressure and import control system (sign) as electronic signals into and carry out Pressure Analysis, and show that whether the air-leakage test result of joint is qualified.
Because the outside of inflating bar 71 upper end is provided with two ventholes 72, charge pressure is even, adds the fillet chamfering that inflation bar top is provided with 5mm, can not damage the O-ring seal in joint, effectively ensure that authenticity and the reliability of air-leakage test.
