Abstract
The utility model relates to a self-sucking pulse reflection ultrasonic wave thickness gauge probe which is composed of a probe body and an annular neodymium iron boron (NdFeB) magnet which is installed at the tail end of the probe body in sleeved mode. A screw hole is installed in the side face of the annular NdFeB magnet which is fixedly connected with the probe body through the fact that a fixing bolt is screwed in the screw hole, and the end face of the tail end of the annular NdFeB magnet and the end face of the tail end of the probe body are located in the same horizontal plane. The annular NdFeB magnet has 25-newton pressure on a detected workpiece. The self-sucking pulse reflection ultrasonic wave thickness gauge probe solves the problem that exerted pressure cannot be controlled during an actual thickness test, enables the thickness test to be standardized and meet a criterion, improves measurement precision, reduces measuring errors caused by coupling layers, and reduces labor intensity.
Description
Technical field
The utility model relates to a kind of self-priming pulse-echo ultrasonic thickness test instrument probe; A kind of specifically self-priming pulse-echo ultrasonic thickness test of constant force instrument probe that is applicable to ferrimagnet; When using this probe that ferrimagnet is carried out thickness measuring; Can between probe and seized workpiece, realize constant suction, to improve the thickness measuring precision.
Background technology
Pulse-echo ultrasonic thickness test technology is used very extensive as a kind of conventional nondestructiving detecting means, but defectives such as discovering device internal corrosion attenuate, layering.Its principle is to utilize double-crystal normal probe to measure ultrasound wave is tried to achieve workpiece in the time that round trip is propagated between the bottom surface on the workpiece thickness.Its computing formula is following: T=ct/2.T representes thickness of workpiece in the above-mentioned formula, and c representes the velocity of wave in the workpiece, and t representes the ultrasound wave time that round trip is propagated in workpiece.When workpiece was carried out thickness measuring, probe will be placed steadily, and the probe applied pressure is wanted suitably; When clearly having stipulated ultrasonic thickness test among the GB/T11344-2008, probe exerted pressure be worth to be required: when probe contacts with test specimen, on popping one's head in, apply the pressure of 20～30N; Guaranteeing between probe and the test specimen good coupling being arranged, and get rid of unnecessary couplant, make measurement face form one deck couplant as thin as a wafer; Reduce the time of sound wave, improve measuring accuracy through coupling layer.The probe that present thicknessmeter has does not have the size that any device control is exerted pressure; The probe that has has installed spring assembly additional; Spring is killed the control that can realize to minimum pressure; But reviewer's manipulation strength is big, and can't realize the control to maximum pressure, possibly cause because of the excessive probe wearing and tearing that cause of exerting pressure.
The utility model content
In view of the foregoing; It is a kind of simple in structure that the purpose of the utility model is to provide; Self-priming pulse-echo ultrasonic thickness test instrument probe easy to use, but between paired pulses reflection supersonic wave thickness meter probe and the seized workpiece constant pressure is provided, to guarantee the precision of thickness measuring.
For achieving the above object, the technical scheme that the utility model adopted is:
A kind of self-priming pulse-echo ultrasonic thickness test instrument probe; Constitute by probe body and the annular ndfeb magnet that is sleeved on said probe body tip; The side of said annular ndfeb magnet is provided with screw; Be connected with said probe body-fixed through in said screw, screwing in set bolt, and the distal end faces of the distal end faces of said annular ndfeb magnet and probe body is positioned on the same surface level.
Said annular ndfeb magnet is 25N to the pressure of seized workpiece.
The beneficial effect of the utility model is: when having solved the check of actual thickness measuring to the uncontrollable difficult problem of exerting pressure; Make the thickness measuring check standardize more, conformance with standard has improved the measurement precision more; Reduced because of the coupling layer errors caused, and reduced labour intensity.

Present embodiment is by probe body 1-1 and be sleeved on the terminal annular ndfeb magnet 2 of said probe body 1-1 and constitute; The external diameter of probe body 1-1 and the internal diameter of annular ndfeb magnet 2 adapt; The side of said annular ndfeb magnet 2 is provided with screw 2-1; Be fixedly connected with said probe body 1-1 through in said screw 2-1, screwing in set bolt 3, and the distal end faces of the distal end faces of said annular ndfeb magnet 2 and probe body 1-1 is positioned on the same surface level.
Select to meet the annular ndfeb magnet 2 of following requirement during use:
F×S
2/（S
1+S
2）=25 （N）
In the formula: F: annular ndfeb magnet is to the suction of seized workpiece, unit: N;
S
1: the area of annular ndfeb magnet, the: ㎡ of unit;
S
2: probe area, the: ㎡ of unit.
Satisfy the annular ndfeb magnet of above-mentioned relation, can realize popping one's head in and seized workpiece between have the constant pressure of 25N.
Annular ndfeb magnet 2 is enclosed within on the probe body 1-1, regulates annular ndfeb magnet 2 positions, its distal end faces and the distal end faces of probe body 1-1 are maintained at the same horizontal plane.Three set bolts 3 are tightened respectively through screw 2-1, made annular ndfeb magnet 2 firmly fixing with probe body 1-1.Regulate supersonic thickness meter 1 according to the check and correction of instrument operation instruction during detection; Seized workpiece sensing face is handled, satisfied the roughness requirement; Apply couplant then; To pop one's head in body 1-1 near seized workpiece, and probe body 1-1 self-priming read supersonic thickness meter 1 and showed numerical value at seized surface of the work, accomplishes this thickness measuring check because of magneticaction this moment.
