Description
Technical field
The utility model relates to a kind of structure of being connected between sensor or waveguide rod and the measurand of being applied in the acoustic emission detection field to realize.
Background technology
Acoustic emission detection is a kind of dynamic detection technology, can detect effectively in the material and damage formed acoustic emission source such as crack propagation, fibre breakage and other form, and can carry out dynamic monitoring to the secondary acoustic emission source that causes such as leaking.But in industrial processes, when using acoustic emission testing technology equipment such as pressure vessel, pipeline being detected,, very difficultly be directly installed on sensor on the surface of detected object if when having high temperature, deep cooling, radiation and burying special operation condition such as ground.Therefore, be badly in need of a kind of bindiny mechanism sensor and measurand are coupled together, consider in the stress wave propagation to require to decay as far as possible little that this just requires this kind bindiny mechanism reasonable in design and can fully be coupled with measurand.
Summary of the invention
In order to overcome in high temperature, deep cooling, radiation and can't to carry out the deficiency of acoustic emission detection when burying special operation conditions such as ground; It is a kind of with sensor, waveguide rod and detected object bindiny mechanism that the utility model provides; It is adsorbed on the measurand through magnetic force; Make between export bar and detected object and can closely contact, thus can carry out high temperature, deep cooling, radiation and bury under the special operation condition such as ground acoustic emission detection and to the dynamic monitoring of acoustic emission source.
The technical scheme of the utility model: this kind is used for acoustic emission detection sensor, waveguide rod and detected object bindiny mechanism; Constitute by disk, hollow cylinder and export bar, wherein, have the magnet embedded groove on the said disk; Wherein be embedded with magnet, magnet is through being bolted on the disk; One end of said hollow cylinder has external thread and the internal diameter diameter greater than export bar, and the internal diameter of the other end of hollow cylinder is identical with the diameter of export bar; Disk is fixed on hollow cylinder and is threaded on the end through being threaded, export bar passes from the other end of hollow cylinder; There is positive stop lug boss an end of said export bar and is drilled with internal thread, and other end cover upper spring also is equipped with jump ring.
The utlity model has following beneficial effect: the utility model is applicable to the acoustic emission detection of ferrimagnet, and mechanism is fixed on the measurand through magnet, and an end and the detected object of export bar fully are coupled, and the other end connects waveguide rod or sensor.When producing acoustic emission signal in the measurand, stress wave can be propagated out through export bar, is received by sensor.This kind of bindiny mechanism is adsorbed on the measurand through magnetic force, make between export bar and detected object closely to contact, thereby can carry out high temperature, deep cooling, radiation and bury under the special operation condition such as ground acoustic emission detection and to the dynamic monitoring of acoustic emission source.Through experiment showed, that this bindiny mechanism can realize the acoustic emission detection under the special operation condition with stable the coupling together of measurand under waveguide rod or sensor and the special operation condition, has expanded the detectable scope of acoustic emission.

Embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
This kind is used for acoustic emission detection sensor, waveguide rod and detected object bindiny mechanism; Constitute by disk 4, hollow cylinder 3 and export bar 2, wherein, have the magnet embedded groove on the said disk 4; Wherein be embedded with magnet 7, magnet 7 is fixed on the disk 4 through bolt 1; One end of said hollow cylinder 3 has external thread and the internal diameter diameter greater than export bar 2, and the internal diameter of the other end of hollow cylinder 3 is identical with the diameter of export bar 2; Disk 4 is fixed on through being threaded on the hollow cylinder 3 screwed ends, and export bar 2 passes from the other end of hollow cylinder 3; There is positive stop lug boss an end of said export bar 2 and is drilled with internal thread, and other end cover upper spring 5 also is equipped with jump ring 6.The installation steps of this mechanism are following: at first disk 4 is fixed on hollow cylinder 3 through being threaded and is threaded on the end; Magnet 7 is fixed on the disk 4 through bolt 1; Export bar 2 passes from the other end of hollow cylinder 3, because there is positive stop lug boss the end of export bar, so export bar can't pass hollow cylinder; At last export bar is overlapped upper spring 5 and jump ring 6 is installed.
This kind of working process of mechanism is following: export bar is had jump ring one end coat couplant; Regulating disk makes magnet fully contact with detected object; Guarantee firm being fixed on the measurand of member, the other end of export bar connects waveguide rod or sensor, can carry out acoustic emission detection.
