Description
Technical field
The utility model relates to air-leakage test technical field, particularly a kind of frock that can be used for different size wave guide member air-leakage test.
Background technology
At present, field is manufactured at microwave device, the work flow of usual employing mainly comprises: machining-soldering-air-leakage test, namely after each independent part is machined, connected by soldering, and be ensure that the waveguide cavity of wave guide member is not at soldered seam place leaky wave, air-leakage test must be carried out after wave guide member manufacture is complete, whether there is penetrability defect to detect waveguide cavity brazed seam place, if existing defects just needs to carry out repair welding, avoid scrapping to eliminate penetrability defect.Because wave guide member size and pattern vary, a general microwave device just needs the air-tightness detection tool of a set of correspondence, cause needing when detecting to process a large amount of detection frocks, which not only adds sense cycle and testing cost, and required a large amount of frocks also need the management carried out, further increase handling cost.Therefore design a kind of general air-tightness detection tool being applicable to most of wave guide member and just very there is realistic meaning.
Utility model content
In order to solve the poor problem of existing wave guide member air-tightness detection tool versatility, the utility model provides a kind of detection frock being applicable to different size wave guide member air-leakage test.This frock effectively for the wave guide member air-leakage test of different size waveguide mouth, can improve the versatility of wave guide member air-tightness detection tool, can raise labour efficiency, and reduces testing cost.
The utility model solves the problems of the technologies described above adopted technical scheme:
A kind of wave guide member air-tightness detection tool, comprises U-shaped support, sprue, adjuster bar and leans against block; Described sprue is arranged in U-shaped support; For being threaded between described adjuster bar with U-shaped support, adjuster bar one end extend in U-shaped support through U-shaped cantilever tip; The described block that leans against is arranged on lower end, U-shaped support both sides respectively, can horizontally slip along U-shaped support; Described sprue is provided with air intake opening and the gas outlet of connection, described gas outlet is arranged on below sprue.
Further, described U-shaped support is at least provided with gathering sill in side; On described sprue, at least side correspondence is connected with guide pole; Described guide pole, through gathering sill, makes sprue can move up and down along gathering sill.
Further, described gathering sill and guide pole quantity are two, are separately positioned on U-shaped support and sprue both sides.
Further, lower end, described U-shaped support both sides is respectively arranged with chute; The described block that leans against is arranged in chute respectively, and leaning against block can horizontally slip along chute.
Further, described gas outlet place is provided with sealing gasket.
The beneficial effects of the utility model are, changing often kind of wave guide member needs a set of correspondence to detect the present situation of frock, achieves the part versatility of air-leakage test, adopts a set of frock can meet the air-leakage test of multiple different size and type of wave guiding element.This tool structure is more rationally, simply, easy to adjust, reduces production cost, improves detection efficiency.

Fig. 3 is the utility model structure upward view.
In figure: 1.U shape support, 2. sprue, 3. sealing gasket, 4. adjuster bar, 5. lean against block, 6. air intake opening, 7. guide pole, 8. gas outlet, 9. gathering sill, 10. chute.
Embodiment
Below in conjunction with accompanying drawing, be described in detail as follows to concrete structure of the present utility model, feature.
Composition graphs 1 and Fig. 2, be a kind of wave guide member air-tightness detection tool, comprise U-shaped support 1, sprue 2, adjuster bar 4 and lean against block 5; Described sprue 2 is arranged in U-shaped support 1; Described adjuster bar 4 with between U-shaped support 1 for being threaded, adjuster bar 4 one end extend in U-shaped support 1 through U-shaped support 1 top; The described block 5 that leans against is arranged on lower end, U-shaped support 1 both sides respectively, can horizontally slip along U-shaped support 1; Described sprue 2 is provided with air intake opening 6 and the gas outlet 8 of connection, described gas outlet 8 is arranged on below sprue 2.
U-shaped support 1 is provided with chute 10 near lower end position, and chute 10 is built with leaning against block 5, and chute 10 is identical with leaning against block 5 quantity, is respectively one, one end, two ends, left and right.Lean against block 5 to horizontally slip along chute 10, regulate the position leaning against block 5, block the waveguide mouth of wave guide member from below, waveguide mouth can be fixed in U-shaped support 1.
Respectively there is a gathering sill 9 at U-shaped support about 1 two ends, on sprue 2, two ends, left and right are respectively connected with a guide pole 7, guide pole 7 and gathering sill 9 match and to be fixed in U-shaped support 1 by sprue 2, and guide pole 7 can move up and down along gathering sill 9, and sprue 2 can be moved up and down in U-shaped support 1.
Rotation adjusting lever 4, makes its length stretched in U-shaped support 1 become large gradually, the lower end of adjuster bar 4 and the upper-end contact of sprue 2, and promotes sprue 2 and move downward.Sprue 2 under the effect of guide pole 7 along gathering sill 9 slide downward, until together with sprue 2 lower end fits tightly with the waveguide mouth upper end of wave guide member, now, align with waveguide mouth in the gas outlet 8 on sprue 2.
Sprue 2 and lean against block 5 and cooperatively interact, is made wave guide member firm by clamping U-shaped support 1 in, and is sealed by the waveguide mouth of sprue 2 by wave guide member, make it can only be ventilated with the external world by the gas outlet 8 on sprue 2.
As shown in Figure 3, set out gas port 8 below sprue 2, gas outlet 8 place is provided with sealing gasket 3, sealing gasket 3 leaves the hole that size equal in gas outlet 8, position are identical, for sealing waveguide mouth.
When using this frock to carry out air-leakage test, wave guide member is placed on and leans against between block 5 and sprue 2, make the gas outlet 8 on waveguide mouth aligning sprue 2, regulate the position leaning against block 5, one end of wave guide member is fixed; Adjustment adjuster bar 4, one end that adjusting lever 4 stretches into U-shaped support 1 acts on sprue 2, and a downward pressure is applied to sprue 2, make to lean against block 5 and sprue 2 clamps wave guide member, sealing gasket now on gas outlet 83 pairs of wave guide member openings seal, to ensure the sealing of frock, thus complete the fixed installation of wave guide member; Then adopt aerating device by air intake opening 6 pairs of wave guide member inflations, carry out the bubble-tight detection of microwave device.
Instructions of the present utility model and accompanying drawing are considered to illustrative and nonrestrictive; on the basis of technical scheme disclosed in the utility model; those skilled in the art is according to disclosed technology contents; without departing from the concept of the premise utility; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
