The eddy current detecting device for the air valve has the advantages of simple structure, small volume, convenient operation, good stability, high sensitivity and no environmental pollution, and can effectively detect the surface defect and material defect of the air valve and can be widely used in the air valve detection.
Description
Technical field
Of the present utility modelly relate to a kind of failure detector, relate in particular to a kind of eddy-current crack detector that detects for air valve, belong to the testing tool class.
Background technology
Air valve usually is important components in power machine, mostly be trumpet type, bell-mouthed outward flange very easily weares and teares, be head it off, usually be connected to overlay cladding anti-corrosion, wear-resisting and that heat proof material is made, but inherent vice may appear in overlay cladding in the welding process, need carry out carrying out flaw detection at its edge joint weld, otherwise in use air valve can cause damaging in spite of wound, with the running of whole equipment of influence.As: in case the inlet and outlet valve generation problem in the common vehicle internal combustion engine will cause vehicle trouble, even influence traffic.At present the detection of air valve is generally adopted the method for dye penetrant inspection, be about to the air valve surface and successively coat penetrating fluid, developer,, survey air valve and whether have defective through infiltration, cleaning, video picture, four steps of observation.But this method can only detect air valve surface opening defective, can't react for the inner material defective of air valve overlay cladding, and can produce than serious environmental in testing process and pollute, and can damage staff's health.
Summary of the invention
The purpose of this utility model provides a kind of the purpose of this utility model and provides a kind of air valve eddy-current crack detector, it is simple in structure, volume is little, can not only detect the air valve surface imperfection effectively, and can also detect the material internal problem, and easy to operate, good stability, highly sensitive free from environmental pollution again.
The designed air valve eddy-current crack detector of the utility model mainly is made up of eddy current flaw detec, adjusting bracket, turntable and probe, adjusting bracket is fixed on the turntable, have rotatable pallet on the turntable, the pallet center has the addendum cone that is used for fixing air valve, probe is fixed by adjusting bracket, and probe is connected with eddy current flaw detec by lead-in wire.
The adjusting bracket of above-mentioned air valve eddy-current crack detector is made up of guide rod, universal adjustment joint and column, and column lower end and turntable are fixed, and guide rod links to each other with column by the universal adjustment joint, and the guide rod front end has the probe connector that is used for fixing probe.The universal adjustment joint guarantees the connection of the relative column of guide rod optional position.
Pallet on the turntable of above-mentioned air valve eddy-current crack detector can be the pallet of electronic or manual control rotation.
The pallet that this pallet is preferably rotated automatically by driven by motor is to realize steadily, to rotate evenly.
The utility model is positioned over tested air valve on the pallet when using, and the addendum cone by the pallet center positions.By regulate the universal adjustment joint make probe along with the guide rod rotation, move, reach the position that flaw detection requires after, static probe.Rotary tray, probe carries out work, each point position to the air valve overlay cladding is detected, detection signal passes to eddy current flaw detec by lead, realize signals collecting, obtain the real time data of flaw detection by eddy current flaw detec, can detect defective by data analysis and have situation, the eddy current test of finishing air valve detects.
The utility model has the advantages that:
1, simple in structure, the eddy current flaw detec higher with sensitivity detects, and not only measure accurately, and loss reduces greatly;
2, this device adopts eddy-current flaw detecting method to replace existing dye penetrant inspection method, and detection speed is fast, and to the detection of overlay cladding more comprehensively, surface and inherent vice all can detect;
3, the adjusting bracket of this device has the guide rod of probe with the universal adjustment connection supports, makes to adapt to the detection of various different angles air valves by the easy to adjust, flexible of probe;
4, this device volume is little, and is easy to operate, pollution-free, guarantees that operating personnel are healthy;
5, probe and the tested air valve surface in this device is contactless, can not damage, the contamination gas valve surface, and probe can be changed as required, and guarantees to detect quality, the serviceable life of prolongation failure detector.
The utility model can be suitable for the detection of various air valves, also can be used for the detection of other parts of similar air valve.
Description of drawings
Fig. 1 is the designed air valve eddy-current crack detector structural representation of the utility model.
Fig. 2 is an air valve eddy-current crack detector work synoptic diagram shown in Figure 1.
Embodiment
In conjunction with specific embodiments the structure and the embodiment of the designed air valve eddy-current crack detector of the utility model is described further with reference to the accompanying drawings below.
Air valve eddy-current crack detector as shown in Figure 1, mainly by eddy current flaw detec 10, turntable 6 with pop one's head in and 8 form, adjusting bracket is fixed on the turntable 6, has rotatable pallet 5 on the turntable 6, and pallet 5 centers have the addendum cone 7 that is used for fixing air valve.Adjusting bracket mainly is made up of guide rod 2, universal adjustment joint 3 and column 4, and column 4 lower ends and turntable 6 are fixing, and guide rod 2 links to each other with column 4 by universal adjustment joint 3.Guide rod 2 front ends have probe connector 1, are used for 8 fixedlying connected with probe, and probe 8 11 is connected with eddy current flaw detec 10 by going between.Guide rod 2 can move and rotate under the effect of universal adjustment joint 3 relative to column 4, regulates the existing to position and angle of probe 8 and detected air valve 9 thus.Eddy current flaw detec 10 11 obtains probe 8 detection signal by going between, and judges through Treatment Analysis whether air valve is qualified.
When flaw detection, detected air valve 9 is placed on the pallet 5 stably, by addendum cone 7 location.Regulate guide rod 2 by universal adjustment joint 3, probe 8 reaches the relative position that flaw detection requires along with guide rod 2 moves or rotates, and is fixing then.Rotary tray 5, air valve 9 together rotates with pallet 5, and air valve 9 probe 8 motions relatively this moment are to detected comprehensive scanning.Probe 8 11 passes to eddy current flaw detec 10 with detection signal by going between, and realizes signals collecting and analysis, finishes the eddy current test to air valve.
Found out that by above-mentioned testing process is simple, detection speed is fast, and is easy to operate, and detection method is more accurate than the method for dye penetrant inspection, has very high practical value.
