Description
Technical field
The present invention is to provide a kind of Diesel Engine's Air Valve failure detector that field of non destructive testing uses.
Technical background
Diesel Engine's Air Valve is completed by single material or various material manufacture, the Diesel Engine's Air Valve manufactured for various material,
Because the material electrical conductivity that valve rod and valve handle are excessively located is different, so EDDY CURRENT can produce wrong report in material transition position, can not
Confirm that valve rod and valve handle transition position whether there is defect.And ultrasound examination means are then without this defect, Pulsed eddy current testing means
More suitable for being detected at the valve rod of Diesel Engine's Air Valve.
The content of the invention
In order to realize Diesel Engine's Air Valve carrying out flaw detection, the present invention proposes a kind of Diesel Engine's Air Valve failure detector.Should
Device solves the technical problem of Diesel Engine's Air Valve Non-Destructive Testing by impulse eddy current and ultrasound examination.
Scheme is used by the present invention solves technical problem：
One end is fixed with tailstock on base, and thimble is housed on tailstock, and PLC is housed in the base other end, is controlled in PLC
The housing of device processed is provided with chuck built with stepper motor, stepper motor end, is equipped with base plane top and moves horizontally motor,
Move horizontally motor one end and be connected with slide rail, ultrasonic probe installed body is housed on slide rail, pulse is housed in thimble inboard
Eddy current probe installed body, ultrasonic probe installed body and pulse eddy current probe installed body are respectively arranged with probe.
Good effect, the present invention are detected a flaw using impulse eddy current to Diesel Engine's Air Valve and valve rod valve seat changeover portion, energy
The defects of enough overcoming Sing plus EDDY CURRENT means, complete to the overall complete detection of Diesel Engine's Air Valve.Suitably it is used as internal combustion
Machine air valve failure detector uses.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
In figure, 1. bases, 2.PLC controllers, 3. stepper motors, 3.1. chucks, 4. tailstocks, 5. thimbles, the spy of 6. ultrasonic waves
Head installed body, 7. slide rails, 8. move horizontally motor, 9. pulse eddy current probe installed bodies.
Embodiment
According to the figure, one end is fixed with tailstock 4 on base 1, and thimble 5 is housed on tailstock, is equipped with the base other end
PLC 2, chuck 3.1 is provided with, is put down in base built with stepper motor 3, stepper motor end in the housing of PLC
Face top moves horizontally motor one end and is connected with slide rail 7, ultrasonic probe card is housed on slide rail equipped with motor 8 is moved horizontally
Mounting mechanism 6, pulse eddy current probe installed body 9, ultrasonic probe installed body and pulse eddy current probe are housed in thimble inboard
Installed body is respectively arranged with probe.
The use of the present invention：
Engine air valve arrangement is to be provided with valve seat, the intake and exhaust for cylinder in valve rod upper end.
In use, air valve one end is held out against by thimble with chuck, air valve is rotated by stepper motor, moved by level
Dynamic slide rail makes the probe of ultrasonic probe installed body be moved along air valve revolution, carries out ultrasonic listening to air valve, passes through simultaneously
Pulse eddy current probe installed body carries out vortex detection to air valve valve seat, realizes the ultrasound of air valve valve rod and valve seat and changeover portion
Ripple detects with vortex, carries out air valve scar defects detection.
Feature：
The present invention can carry out ultrasonic wave with valve seat and changeover portion to the valve rod of engine air valve and vortex detects, and air valve is entered
Row flaw detection.
