Description
Technical field
The air seal that the utility model relates to metal device detects, the automation equipment that a kind of metallic bellows impermeability detects.
Background technology
The use of corrugated tube generally all will be formed the modular construction that two ends are welded with method indigo plant, and the corrugated tube inner chamber is filled with the gas or the liquid medium of certain pressure during use, therefore must guarantee its sealing.The sealing of corrugated pipe products detects and adopts the pressurized seal test usually.Corrugated tube has wide range of applications, specification is various in style, and the structure of two hold-carrying indigo plants also is various, and this detects to impermeability and brings big difficulty, being installed and sealing the method that is difficult to take standard universal, generally all is to adopt the manual sealing that is installed of simple packoff.Operating efficiency is low, and it is unreliable to seal, and needs to reduce pressure seal sometimes, causes the reliability of airtight detection to reduce.Therefore need to improve the technical measures of this link, but also do not have general corrugated tube airtight detecting apparatus at present.
Summary of the invention
The purpose of this utility model provides a kind of corrugated tube air-tightness detection device, can realize chucking, detection fast to dissimilar corrugated tube class components, improves airtight detection efficiency of corrugated tube and reliability.
The corrugated tube air-tightness detection device comprises corrugated tube jig, Displaying Meter, tank, pneumatic control circuit, it is characterized in that: the corrugated tube jig is placed on the hole of clamping worktable, and corrugated tube jig base is positioned at cylinder, cylinder piston top; Corrugated tube jig base core bar center is porose to be reached in the logical corrugated tube of the air admission hole of radially hunting leak.
The design's pick-up unit cooperates general automated exchanged cutter part with special-purpose corrugated tube jig, the locking screw screw bolt and nut of corrugated tube jig top can be realized loading and unloading fast to various dissimilar corrugated tubes, and, finish efficient airtight detection to multi-form corrugated tube by general clamping device realization locking and sealing fast.Adopt the pneumatic control circuit that does not have electricity to control, safety, efficient, cleaning.Whole device is simple to operate, convenient mounting and clamping.

Embodiment
This corrugated tube air-tightness detection device, comprise jig, Displaying Meter, tank, pneumatic control circuit that corrugated tube is mounted in it, see Fig. 1, it is characterized in that: the corrugated tube jig is placed on the hole of clamping worktable 12, corrugated tube jig base 10 is positioned at cylinder 14, cylinder piston 13 tops, and cylinder 14 is fixed on the clamping worktable 12 times; See Fig. 2: the core bar of corrugated tube jig base 10 has center pit and radially hunts leak air admission hole 7 logical corrugated tube 5 inner chambers.
Many entad slideways are arranged around the hole among Fig. 1 on the clamping worktable 12, the slide block 11 and 11 ' on it is symmetrically placed in the slideway, and slide block 11 is identical with ripple pipe clamp tool base 10 profiles among Fig. 2 with 11 ' entad interior shape.
Referring to Fig. 2: on the corrugated tube jig base 10 annular groove is arranged,, corrugated tube lower flange sealing ring 9 is arranged in the groove perpendicular to jig outer cover 2 stiles.The core bar of corrugated tube jig base 10 has center pit and radial hole 7, and rod end is the indentation path, and embeds upper flange encapsulation fitting 6: the jacking block on spring and top thereof.
Corrugated tube jig outer cover 2 is a cylindrical frame, and the framework upper center of circle is not isometrical boss platform downwards, and center pit and annular groove are arranged, and corrugated tube upper flange sealing ring 4 is arranged in the groove.Lower edge and jig base 10 that 2 next weeks of outer cover and outer cover stile are rectangular are measure-alike.
The operation of pick-up unit: earlier ripple pipe clamp tool base 10 among Fig. 1 is placed on the clamping worktable 12, and on jig base 10 core bars, add the spring and the jacking block of flange seal annex 6, see Fig. 2, pack into then and have lower flange 3,8 corrugated tube 5, buckle corrugated tube jig outer cover 2 again, after corrugated tube jig base 10 is embraced in hand propelled slide block 11 and 11 ' action, cylinder 14 starts, by cylinder piston 13 Fig. 1 corrugated tube jig assembly is risen overally and make a left side, right slide block 11,11 ' pushes down the outer cover 2 on the corrugated tube jig base 10, finish the ring of two seals up and down 4 to corrugated tube, 9 give compression, screw in the upper locking nut 1 of corrugated tube jig, among Fig. 1 all assemblies of ripple pipe clamp tool promptly finish sealing give compression and locking becomes one.Cylinder 14 restores afterwards, and symmetrical slide block 11 and 11 ' opens, and promptly finishes the sealing chucking process to corrugated tube jig assembly.Corrugated tube jig assembly is together put into tank, after corrugated tube jig base 10 center pits feed air pressure, just can carry out the impermeability detection.After detection is finished, corrugated tube jig assembly is reset back on the automated exchanged cutter platform 12, after corrugated tube jig assembly is embraced in slide block 11 and 11 ' action, cylinder 14 action rises overally bellows component to make left and right slide block 11,11 ' push down corrugated tube jig assembly, can screw off corrugated tube jig upper locking nut 1 this moment, same afterwards cylinder 14 restores, fall corrugated tube jig assembly, left and right sides slide block 11 and 11 ' opens, take off corrugated tube jig outer cover 2, take out corrugated tube 5 and just finished the one-time detection process.
