Tapped through hole；Four angles of the casing of described coupling pressure adjusting means are the support of high intensity sucker respectively with four bottoms
Stud is fixing to be connected.
Compared with prior art, the invention has the beneficial effects as follows: this probe fixing device is simple to operation, during measurement without
Need hands grasping, coordinated by upper removable slide plate and supporting studs and be accurately controlled coupling pressure, be prevented effectively from test
During coupling pressure fluctuation and the measurement error that produces.Apparatus of the present invention volume is little portable simultaneously, can be by ultrasonic testing
Probe is fixed on workpiece smoothly, can realize the single independent operation of all positon, accurately measure.Additionally by regulation supporting studs
Height, be adapted to there is certain high low head and the component surface of radian.
The use process of the present invention is:
1, sample tested surface polished flat and use alcohol washes so that it is reaching to test required cleaning degree requirement, in order to
High intensity sucker stably adsorbs on sample；
2, ultrasound probe is fixed on probe clamping device, this device is placed on tested surface, makes ultrasound wave visit
Head measuring surface is parallel with surface to be measured；
3, the transmitting-receiving two-end at ultrasound wave is coated with and spreads a certain amount of couplant, adjusting apparatus position so that ultrasound probe
Center alignment tested point；
4, lower repoussage device make the high intensity sucker suction of supporting studs on the surface of component to be measured, thus by this dress
Putting and be fixed on sample, now ultrasound probe is together with moving certain distance on lower removable slide plate, is obtained by pressure transducer
Coupling pressure now；
5, rotate force adjustment screw, and then control the flexible of spring regulates coupling pressure, according to the reading of pressure transducer
Determine whether to reach the coupling pressure value of requirement；
6, the measurement of residual stress can just be carried out after waiting pressure transducer numerical stability.
Further, spring inner of the present invention is provided with the slide bar for supporting spring, described slide bar lower end with under can
The upper surface of moving slide board is fixing to be connected；Described slide bar upper end is free end, upper removable slide plate is provided with and passes for slide bar
Slide bar through hole.
Slide bar supports the spring of softness and deforms in the prescribed direction, is perpendicular to lower removable slide plate imposed load.
Further, lower removable slide plate of the present invention, middle fixing plate and upper removable slide plate are square, described
The spring being fixed on lower removable slide plate upper surface is four, is distributed on four angles of lower removable slide plate, symmetrical.
Four springs can be by removable slide plate under being applied to of the uniform load suffered by upper moving slide board, it is to avoid eccentric force
Generation.
Further, pressure transducer display screen of the present invention electrically connects with pressure transducer, is arranged at removable cunning
On the upper surface of plate.
Pressure transducer and pressure transducer display screen can show the stressing conditions of ultrasonic probe in real time
Further, supporting studs top of the present invention is threaded, and bolts with the casing of coupling pressure adjusting means, logical
Cross location nut level altitude.
On the tested surface of certain high low head, four can be regulated according to the situation that is uneven on surface to be measured and support spiral shell
The relative altitude of the location nut on post so that the measuring surface of ultrasonic probe is parallel with tested surface.
