Description

A kind of aluminum component leak detecting device
Technical field
The utility model relates to checkout equipment field, more specifically, relates to the equipment of measuring sealing.
Background technology
For the aluminum component of making by aluminium sheet, much all there is higher sealing requirements, for the detection of above-mentioned aluminum component, conventionally adopt following methods; Each opening part sealing of aluminum component, and then by a forcing pump, gas tank is inflated, gas tank and aluminum component are communicated with; After having inflated, close inflator pump, now gas tank is identical with pressure in aluminum component cavity, and tensimeter is set on gas tank.If tensimeter force value declines after aluminum component is revealed certain hour.But said apparatus, if aluminum component pore hour, stand-by period that need to be longer can judge whether aluminum component is revealed.
For the problems referred to above, the applicant has applied for a kind of aluminum component leak detecting device, mainly comprise gas tank, on gas tank, draw the adapter for being connected with measured object, on gas tank, be communicated with air pump, slide rail is set in gas tank, on slide rail, slide dividing plate is set, and dividing plate is separated into two mutual disconnected chambers gas tank, on dividing plate, offer through hole, on through hole, be provided for closing and opening the control device of described through hole, also comprise for measuring the detecting unit of described dividing plate displacement, by pressure change amount being converted to the displacement of dividing plate, judge whether aluminum component has pore, but in process on probation, find due to dividing plate and slide rail sealing undertighten, caused accuracy of detection reduction.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of aluminum component leak detecting device, by pressure change amount being converted to the displacement of dividing plate, judges whether aluminum component has pore, and detection speed is fast, and precision is higher.
The utility model is achieved by the following technical solution: aluminum component leak detecting device, comprise gas tank, on described gas tank, draw the adapter for being connected with measured object, on described gas tank, be communicated with air pump, in described gas tank, slide rail is set, on described slide rail, slide dividing plate is set, and described dividing plate is separated into two mutual disconnected chambers gas tank, on described dividing plate, offer through hole, on described through hole, be provided for closing and opening the control device of described through hole, also comprise for measuring the detecting unit of described dividing plate displacement, one circle mounting groove is set in described dividing plate periphery, on described mounting groove, seal is set, described seal comprises the end of narrow contracting, the afterbody expanding and the connecting portion that connects end and afterbody.
In technique scheme, described control device comprises baffle plate, and described baffle plate drives by motor, by motor, is driven baffle plate to make flapper closure or is opened described through hole.
The utlity model has following beneficial effect: the utility model judges by pressure change amount being converted to the displacement of dividing plate whether aluminum component has pore, and detection speed is fast, and precision is higher.And dividing plate and slide rail coordinate more tight, be unlikely to produce and reveal on slide rail and dividing plate, thereby further improved accuracy of detection.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic top plan view of the utility model dividing plate.
Fig. 3 is the cooperation schematic diagram of the utility model dividing plate and slide rail.
Embodiment
The utility model is described in further detail to (attached number in the figure 1 is object to be detected) below, referring to Fig. 1 to Fig. 3, a kind of aluminum component leak detecting device, comprise gas tank 3, on described gas tank 3, draw the adapter 2 for being connected with aluminum component, on described gas tank 3, be communicated with air pump 4, at the interior slide rail 6 that arranges of described gas tank 3, on described slide rail 6, slide dividing plate 5 is set, and described dividing plate 5 is separated into disconnected the first chamber 30 and the second chamber 31 mutually air pump 4, on described dividing plate 5, offer through hole 8, on described through hole 8, be provided for closing and opening the control device of described through hole 8, when through hole 8 is opened, described the first chamber 30 and the second chamber 31 are communicated with, in described dividing plate 5 peripheries, a circle mounting groove 50 is set, on described mounting groove 50, seal 9 is set, described seal 9 comprises the end 90 of narrow contracting, the afterbody 92 expanding and the connecting portion 91 that connects end 90 and afterbody 92, between end 90 and afterbody 92, form groove 93.When air pump 4 starts gas tank 3 inflation, the pressure moment increase of the first chamber 30, now the partial pressure in the first chamber 30 enters in the groove 93 on seal 9 tops along the gap of dividing plate 5 and slide rail 6, the outer eaves stress balance in 90 liang of ends now, can not be subject to force unbalance to cause leaking because seal 9 and slide rail 6 tops produce because air pressure is compressed.
Also comprise that described control device comprises baffle plate 7 for measuring the detecting unit of described dividing plate 5 displacements, described baffle plate 7 drives by motor.
Below the utility model principle is further described: during use, first by passing into a certain amount of pressurized air in 4 pairs of gas tanks 3 of air pump, during inflation, through hole 8, in open mode, is then closed air pump 4, closes through hole 8 simultaneously, now dividing plate 5 is positioned at an equilibrium position, detecting unit records above-mentioned position, keeps above-mentioned state certain hour, and detecting unit detects the position of described dividing plate 5 again, if the position of dividing plate 5 has greatly changed, think and there is defect in object to be detected sealing.
In the present embodiment, detecting unit adopts the rectilinear transducer and the processor being connected with sensor (or PLC) of installing on slide rail 6, because the detection for dividing plate 5 positions is known for those skilled in the art, therefore the detection principle of detecting unit is not described in detail in an embodiment.
