Description

Anordning ved ultralydsonde. Device by ultrasound probe.

Foreliggende oppfinnelse angår roterende ultralyd-sonder for undersøkelse av arbeidsstykker, særlig proveobjekter med sirkulært tverrsnitt, f.eks. et stålror, som beveges i en lengderetning, idet sonden har en stator med en gjennomgang for den gjenstand som skal proves, en rotor montert på statoren for dreining omkring gjennomgangens akse, en ultralydgenerator montert på rotoren og minst en væsketilforselskanal i statoren for tilforsel av koplingsvæske til ultralydgeneratoren. The present invention relates to rotating ultrasound probes for the examination of workpieces, in particular sample objects with a circular cross-section, e.g. a steel rod, which is moved in a longitudinal direction, the probe having a stator with a passage for the object to be tested, a rotor mounted on the stator for turning around the axis of the passage, an ultrasonic generator mounted on the rotor and at least one fluid supply channel in the stator for supplying coupling fluid to the ultrasound generator.

Det er et formål med oppfinnelsen å skaffe en sonde av den nevnte art, som kan benyttes sammen med en generator som roterer med stor hastighet i forhold til overflaten av en i lengderetningen beveget gjenstand med sirkulært tverrsnitt, f.eks. It is an object of the invention to provide a probe of the aforementioned kind, which can be used together with a generator which rotates at high speed in relation to the surface of a longitudinally moving object with a circular cross-section, e.g.

et stålror. a steel rudder.

Oppfinnelsen utmerker seg ved at ultralydgeneratoren, som bæres av rotoren, dreier seg i forhold til to sylindriske overflater på statoren omkring en ringformet fordypning mellom de sylindriske overflater og at væsketilfSrselskanalen tilfores koplingsvæske gjennom væskeavlopsåpninger ut i den ringformede fordypning for kopling av ultralydgeneratoren til provegjenstanden, og koplingsvæsken som strommer fra den ringformede fordypning langs de sylindriske overflater, danner et væskelager mellom statoren og provegjenstanden. The invention is distinguished by the fact that the ultrasonic generator, which is carried by the rotor, rotates in relation to two cylindrical surfaces on the stator around an annular recess between the cylindrical surfaces and that the liquid supply channel is supplied with coupling fluid through liquid drain openings into the annular recess for connecting the ultrasonic generator to the test object, and the coupling fluid flowing from the annular recess along the cylindrical surfaces forms a fluid reservoir between the stator and the specimen.

Fordypningens aksiale lengde holdes fortrinnsvis The axial length of the recess is preferably maintained

på et minimum (dvs. ikke vesentlig lenger enn det er nodvendig for å tillate montering av generatoren eller generatorene). at a minimum (ie no significantly longer than is necessary to allow installation of the generator or generators).

Dybden (dvs. den radiale utstrekning) av fordypningen holdes også fortrinnsvis på et minimum. Foringsbanens aksiale lengde er fortrinnsvis flere ganger dens diameter. The depth (ie the radial extent) of the recess is also preferably kept to a minimum. The axial length of the lining web is preferably several times its diameter.

Fordypningen har fortrinnsvis ringform. Den ringformede fordypning kan inneholde et antall ultralydgeneratorer med innbyrdes avstand rundt denne. The recess is preferably ring-shaped. The annular recess can contain a number of ultrasound generators spaced around it.

Foringsbanen er fortrinnsvis anordnet i en stator mens fordypningen er anordnet i en rotor, The liner is preferably arranged in a stator while the recess is arranged in a rotor,

I det folgende skal som et eksempel beskrives en utforelsesform av oppfinnelsen under henvisning til tegningene, hvor fig. 1 er et skjematisk isometrisk snitt av en ultralydsonde, fig, 2 er et sideoppriss av sondehodet på fig, 1 vist i snitt etter linjen 11 — 11 på fig. 3 og fig. 3 er et halvt snitt etter linjen 11I-l11 på fig. 2. In the following, as an example, an embodiment of the invention will be described with reference to the drawings, where fig. 1 is a schematic isometric section of an ultrasound probe, fig. 2 is a side elevation of the probe head in fig. 1 shown in section along the line 11 — 11 in fig. 3 and fig. 3 is a half section along the line 11I-111 in fig. 2.

En bunnplate 1 bærer to endeplater 2 adskilt ved hjelp av to par avstandsstenger 3, 4, Et rorformet statorelement 6 av blybronse passer inn i en messingbossing 7 i hver endeplate og en indre hylse 8 av rustfritt stål med hard overflate passer inn i hvert statorelement. Hylsene B ligger i forlengelsen av hverandre for å skaffe en foringsbane for et stålror som skal proves og hylsenes innvendige diameter er slik at bare en liten klaring foreligger mellom hylsene og stålroret. En rotor 10 av Delrin passer omkring yttersiden av statorelementene 6, De til-støtende ender av statorelementene 6 er aksialt adskilt en liten avstand og inn i dette mellomrom strekker seg en ringformet ribbe 10a på rotoren radialt innover, idet denne ribbe er forsynt med en grunn ringformet fordypning 10b med åpning mot rotasjonsaksen. Den ringformede ribbe 10a er forsynt med kanaler i form av huller 10c som forer til fordypningen 10b og ligger overfor ringformede spor 10d i endene av statorelementene 6, hvilke spor 10d er forbundet med aksiale kanaler 10e i statorelementene. Således kan den ringformede fordypning 10b forsynes med vann gjennom de aksiale kanaler 10e, de ringformede spor 10d og hullene 10c. Ytterligere aksiale boringer 10f i statorelementene 6 mater vann mellom rotorens 10 og statorelementenes 6 overflater for å smore lagringsflåtene. Tetninger 12 griper inn mellom bossingene 7 og tetter stotteringer 13 på rotoren 10 for å hindre eller redusere til det minst mulige lekkasjen av lagervann. En remskive 15 er montert på rotoren 10, slik at denne kan drives til rotasjon ved hjelp av en rem 16. Ultralydgeneratorer i form av piezo-elektriske krystaller 17 med fast vinkel montert i uttagbare holdere 18 er anordnet med avstand omkring den ringformede fordypning 10b, idet krystallene 17 er slik anordnet at de befinner seg meget nær inntil overflaten av det ror som skol proves (fortrinnsvis mindre enn 4,7 mm fro denne overflate). Holderne 17 er anbrakt i radiale boringer 19 i rotoren 10. Elektriske forbindelser til krystallene 17 er laget gjennom messing-sleperinger 21 båret på rotoren 10 og i kontakt med horster 20 i holdere 22 festet på en support 23, idet horstene 20 er til-koplet koplingsbdssinger 25 ved hjelp av ledere 26. Sleperingene 21 har innbyrdes avstand ved hjelp av avstandsringer 27 av Delrin eller et annet elektrisk isolerende materiale. A base plate 1 carries two end plates 2 separated by means of two pairs of spacer bars 3, 4, A rudder-shaped stator element 6 of lead bronze fits into a brass bossing 7 in each end plate and an inner sleeve 8 of stainless steel with a hard surface fits into each stator element. The sleeves B lie in extension of each other to provide a liner path for a steel rudder to be tested and the inner diameter of the sleeves is such that only a small clearance exists between the sleeves and the steel rudder. A rotor 10 of Delrin fits around the outside of the stator elements 6. The adjacent ends of the stator elements 6 are axially separated by a small distance and into this space an annular rib 10a on the rotor extends radially inwards, this rib being provided with a shallow annular recess 10b with opening towards the axis of rotation. The annular rib 10a is provided with channels in the form of holes 10c which lead to the recess 10b and lie opposite annular grooves 10d at the ends of the stator elements 6, which grooves 10d are connected to axial channels 10e in the stator elements. Thus, the annular recess 10b can be supplied with water through the axial channels 10e, the annular grooves 10d and the holes 10c. Further axial bores 10f in the stator elements 6 feed water between the surfaces of the rotor 10 and the stator elements 6 to lubricate the bearing floats. Seals 12 engage between the bossings 7 and seal stutterings 13 on the rotor 10 to prevent or reduce to the smallest possible leakage of storage water. A pulley 15 is mounted on the rotor 10, so that it can be driven into rotation by means of a belt 16. Ultrasound generators in the form of piezoelectric crystals 17 with a fixed angle mounted in removable holders 18 are arranged at a distance around the annular recess 10b, in that the crystals 17 are arranged so that they are very close to the surface of the rudder to be tested (preferably less than 4.7 mm from this surface). The holders 17 are placed in radial bores 19 in the rotor 10. Electrical connections to the crystals 17 are made through brass drag rings 21 carried on the rotor 10 and in contact with horsters 20 in holders 22 fixed on a support 23, the horsters 20 being connected coupling bdssinger 25 by means of conductors 26. The slip rings 21 are spaced from each other by means of spacer rings 27 of Delrin or another electrically insulating material.

Ved bruk fores et stålror som skal proves, gjennom foringsbonen dannet av hylsene 8. V/ann tilfores som beskrevet ovenfor til den ringformede fordypning 10b og strommer ut for å fylle spalten mellom roret og hylsene 8 og derved frembringe en flytende lagring. Etter hvert som roret passerer gjennom foringsbanen roteres rotoren 10 hurtig og de onskede prover foretas. In use, a steel rudder to be tested is fed through the liner bone formed by the sleeves 8. Water is supplied as described above to the annular recess 10b and flows out to fill the gap between the rudder and the sleeves 8 and thereby produce a liquid storage. As the rudder passes through the liner, the rotor 10 is rotated rapidly and the desired tests are made.

Anvendelsen av et vannlager mellom statorelementene 6 og rotoren 10 reduserer akkustisk lyd til et minimum, mens bruken av en smal, grunn fordypning 10b i rotoren 10 for å bibeholde en ring av vann tillater rotasjonshastigheter på 5000 o/min med gode ultralydsignaler. (Ved anlegg med enkle fri vannstråler som slår mot rorets overflate er rotasjonshastigheten begrenset til ca. 1000 o/min fordi strålene brytes opp på grunn av sentrifugal-kraften). Vannets bone mellom krystall og ror er tilstrekkelig kort til at en puls-gjentagelsesfrekvens på 50.000 pulser pr. sekund er mulig. Tre reflekterte pulser kan oppnås fra hver feil og feil såvidt korte som 1,55 mm kan oppdages. Det kan oppnås et meget godt forhold mellom signal og stoy. Anordningen er særlig anvendelig for ror med liten utvendig diameter, f.eks. 25,4 mm. The use of a water reservoir between the stator elements 6 and the rotor 10 reduces acoustic noise to a minimum, while the use of a narrow, shallow depression 10b in the rotor 10 to maintain a ring of water allows rotation speeds of 5000 rpm with good ultrasonic signals. (In systems with simple free water jets that hit the surface of the rudder, the rotation speed is limited to approx. 1000 rpm because the jets are broken up due to the centrifugal force). The water's bone between crystal and rudder is sufficiently short that a pulse repetition frequency of 50,000 pulses per second is possible. Three reflected pulses can be obtained from each defect and defects as short as 1.55 mm can be detected. A very good ratio between signal and noise can be achieved. The device is particularly applicable for rudders with a small external diameter, e.g. 25.4 mm.

Krystallene kan uten videre skiftes ut som folge The crystals can be easily replaced as a result

av bruken av uttagbare holdere. Ved den viste anordning er der anbrakt fire krystaller. Det er mulig å anvende to krystaller for detektering av langsgående feil ved hjelp av skjærbolger som drives frem i motsatte retninger. Et eller to krystaller kan anvendes for å sende ut skjærbolger på en slik måte at tverrgående feil kan detekteres. Det er også mulig å benytte ett krystall-for kontroll av kontinuerlig tykkelse. of the use of removable holders. In the device shown, four crystals are placed. It is possible to use two crystals for detecting longitudinal faults by means of shear waves which are driven forward in opposite directions. One or two crystals can be used to emit shear waves in such a way that transverse defects can be detected. It is also possible to use one crystal for continuous thickness control.

Hylsene kan skiftes for tilpasning til et begrenset område av rdrdiametere, idet det alltid er nddvendig at bare en liten klaring foreligger mellom roret og hylsene. The sleeves can be changed for adaptation to a limited range of tube diameters, as it is always necessary that there is only a small clearance between the tube and the sleeves.
