Once fixture deck 16,116,216 is loaded onto in workstation 12, it just can receive part (step 308) to be tested.At upper fixture 18 and lower clamp 20, by leak-testing workstation 12 after separated and joint, part 21 is received between fixture 18 and lower clamp 20.Part 21 can be placed in the inside middle space 28 of opening of leak-testing workstation 12 and on lower clamp 20.Part 21 can by as in Fig. 7 and Fig. 9, with the mechanical arm 100 shown in way of example, be received between fixture 18 and lower clamp 20.In alternatives, part 21 can be manually placed in leak-testing workstation 12 and be received within on lower clamp 20 by operator.Preferably, fixture deck 16,116,216 has been arranged in leak-testing workstation 12 and is separated when part 21 can be used for leak-testing.Mechanical arm 100 or operator can for example obtain part 21 from adjacent machine work workstation or tote-box, or part can be pulled out from adjacent assembly line.In another kind of configuration, other conveyer system known in the art or materials conveying system can be used to part 21 location and are arranged on lower clamp 20.Once part 21 is positioned on lower clamp 20 and is positioned in workstation 12, actuator 36 just can be reduced to upper fixture 18 on part 21 (as schematic cross sectional views in Figure 10 A to Figure 10 C of the line 10-10 intercepting by generally along Fig. 9 usually represents).
Method 300 is also included in the interior step 310 of setting up enclosure space of part 21.Enclosure space can be by the wall/surface of part 21, in the surface of the surface of lower clamp 20, upper fixture 18 and/or the actuator of leak-testing workstation 12 123,124,125 one partly limits (referring to Figure 10 A to Figure 10 C).As used herein, " sealing " space is can be pressurized and/or maintain such pressure and do not have the space (that is, the opening of all expected designs is all by suitable fixture Fluid Sealing) of any unexpected opening.
The fluid such as air pressurize (step 312) can be then used in this space.Method 300 can then comprise the step 314 that monitoring pressure fluid leaks with test fluid.If there is hole in the structure of part 21, estimate that enclosure space can not maintain constant pressure.
As shown in Figure 10 A to Figure 10 C, in the step of the interior formation enclosure space of part 21 (this space can along the side (step 310) of part 21), can use upper fixture 18 to carry out together with test feature 60 with lower clamp 20, test feature 60 is obturator 21,21 ', 21 ' on one's own initiative ' in various apertures.As shown in the figure, each Element Design (for example, part 21,21 ', 21 ' ' respectively) can comprise the hole/aperture of unique patterns, and this hole/aperture for example can finally be used for flexible pipe, pipe or other device/sensor to be connected to corresponding part.In order to form the enclosure space (step 310) that may be able to maintain pressure, the hole of each particular design must be sealed.For example, part 21,21 ', 21 ' ' can be various valve bodies, torque converter shell, engine cylinder-body, case of transmission and/or cylinder cover.
More specifically, Figure 10 A to Figure 10 C illustrates separately and is designed for respectively the slightly different part of sealing 21,21 ', 21 ' ' the embodiment of fixture deck 16,116,216.In each embodiment, corresponding part 21,21 ', 21 ' ' can under the help of elastomeric seal 110, partly paste lower clamp 20 sealings.The clamp 120 of hydraulic actuation can be applied to controlled force of compression each part 21,21 ', 21 ' ', this power can force part to seal and contact fully with seal 110.Should be appreciated that pneumatic, mechanical or dynamo-electric clamp can substitute hydraulic clamp equally.
Referring to Figure 10 A, part 21 can comprise for example three different openings 130,131,132.When sealing, part 21 can restriceted envelope 140 together with any sealing mechanism or activatable test feature.As mentioned above, opening 130 can be used lower clamp 20 to seal with together with activatable test feature such as seal 110.Similarly, such as the activatable test feature of another kind of the clamp 120 of hydraulic actuation, can be configured to sealed open 131, this test feature also applies force of compression against part 21.Finally, opening 132 can be sealed by the 3rd activatable test feature, and this test feature can be to extend to the plunger 121 of the hydraulic actuation of occlusion of openings 132 effectively.Plunger 121 can comprise the ability that one or more packing rings or O-ring packing provide leak-tight seal to improve it.After upper fixture 18 is reduced on part 21, clamp 120 and plunger 121 can activated (via controller 38) to advance towards part 21, until they with the power contact part 21 of minimum threshold amount with enclosure space 140 fluidly.
Figure 10 B illustrates the sealing of part 21 ', and the part 21 providing in Figure 10 A is provided this part in design, but it comprises the 4th opening 133.As shown in the figure, lower clamp 20 sealable openings 130, clamp 120 sealable opening 131, the first hydraulic actuation plungers 123 can be used to sealed open 132, and the second hydraulic actuation plunger 124 can be used to sealed open 133.Part 21 ', lower clamp 20, clamp 120 and plunger 123,124 can together with restriceted envelope 142.
Finally, Figure 10 C illustrates the part 21 ' that comprises five different openings 130,131,132,133 and 134 ' embodiment.In this embodiment, opening 130-133 is sealed in the similar mode being provided with Figure 10 B, and opening 134 is by the 3rd hydraulic actuation plunger 125 sealings.Once clamp 120 and plunger 123,124,125 activated, just can limit three different spaces 143,144,145 that may all need leak-testing.
Although Figure 10 A to Figure 10 C illustrates three kinds of similar modes that form enclosure space roughly, these technology intentions are exemplary purely.It is contemplated that, the personnel that are familiar with part tensioning technique can create similar fastening layout, to seal any thin-walled parts 21,21 ', 21 ' that need to carry out leak-testing '.The concrete layout of plunger, clamp, seal or other activatable test feature should not be used for limiting the scope of the invention.
Again referring to Fig. 8, once fixture 18,20 obturator 21,21 ', 21 ' effectively ' to form one or more enclosure spaces, the one or more enclosure spaces that correspondingly form just can be by the pressurized with fluid (step 312) such as air.As shown in Figure 10 A to Figure 10 C usually, this pressurization can be undertaken by supplying opening with controlled manner supply by fluid by the pressure fluid such as forced air 150, this opening for example can be arranged on, in one or more plungers (, plunger 123,125) and/or be arranged in lower clamp 20.In order to form as discussed above " enclosure space ", if there is not the opening of intentional design except one or more fluid supply openings in part, space should be considered as to " sealing ".
In order to detect leakage (step 314), controller 38 can be compared the sensor parameter of the pressure fluid in enclosure space with the predicted value of identical parameters.For example, controller 38 can be monitored the actual pressure in space, for example, for example, by being integrated in plunger (plunger 121) or the pressure transducer being integrated in lower clamp 20 carries out.As shown in Figure 11 A usually, vertical axis representation space pressure 151 wherein, horizontal axis represents the time 152, in the situation that the pressurization period of given fixedly duration, controller 38 can then compare the pressure distribution 153 and the pressure distribution 154 of estimating of actual sensed.If exist and decline or deviation 155 (as shown in the figure) in actual pressure 152, controller 38 can be indicated to exist and be leaked.Alternatively, as shown in Figure 11 B roughly, controller 38 can be arranged on the flow that the monitoring of mass flow sensor between pneumatic control module 52 and space enters the air in space by use and detect leakage, wherein vertical axis represents to enter the total mass flow rate 156 of the air in space, and horizontal axis represents the time 152.Controller 38 can be followed the actual total mass flow rate 157 and the total mass flow rate 158 of estimating of the air that relatively enters space.If air 150 inflow space continuously after estimating to be fully pressurized, controller 38 can be indicated and be had leakage.
In order to ensure any leakage (for example, the pressure drop sensing or the MAF increasing continuously) all owing to part 21,21 ', 21 ' ', rather than the tprque convertor between interface 30 and upper fixture 18, can be in test part 21,21 ', 21 ' ' before convection cell unitor carry out individually leak-testing.Can between lower connection panel 46 and various test feature 60, carry out unitor test by closing the valve 160 being arranged on upper fixture 18.Can then be similar to the test routine of step 312 and 314 (above-mentioned), the integrality of the tprque convertor with test setting between connection panel 45,46.For example, can be pressurized until valve-off 160 from various fluid lines pneumatic and/or that hydraulic control module extends.Then, can be in controller 38 place's monitoring pipe linear pressures and/or the mass rate that enters the fluid of pipeline, to determine at unitor place whether have any fluid loss, this loss can be indicated leakage.During the initialization routine that this class testing can be carried out after new deck 16,116,216 is loaded into workstation 12, carry out.
Finally, after completing test routine (, after step 314), can by with part 21,21 ', 21 ' ' each plunger, clamp or other the activatable test feature 60 that engage are from part retraction (that is, separation) and be back to " initially " state.This retraction can be confirmed separately and is communicated to controller 38 via electronic control module by the one or more sensors that are associated with each feature 60.Once confirm all test feature 60 all with part 21,21 ', 21 ' ' separated, actuator 36 just can rise upper fixture 18 from lower clamp 20, and can fetch part 21,21 ', 21 ' '.At part 21,21 ', 21 ' ' remove after, or can load new similar part to test, or actuator 36 can roll back upper fixture for 18 times on lower clamp 20, and wherein whole deck 16,116,216 can be replaced by the different fixture deck 16,116,216 from different carrying shuttle car 14,114,214.
