Abstract
The invention relates to a normal probe with pressure display for ultrasonic testing and belongs to the technical field of nondestructive ultrasonic testing. The normal probe comprises a probe, wherein a jack for connection of a wire is formed on the periphery of the probe; the normal probe is characterized in that a pressure sensor is arranged at a testing end of the probe; the pressure sensor is used for measuring the contact pressure between the probe contact surface and the tested part surface; a display screen is arranged at the other end of the probe back to the testing end; the pressure sensor is connected with the display screen through a converter; and the display screen is used for displaying a pressure value of the pressure sensor. When the normal probe with pressure display for ultrasonic testing provided by the invention is used for performing nondestructive ultrasonic testing, an operator who holds the normal probe by hand can perform the contact test on a workpiece surface by holding the probe by hand while visually inspecting and monitoring the contact pressure between the probe and the workpiece surface on the display screen, so as to maintain the contact pressure in the testing process within an allowed scope and prevent the measurement deviation caused by the contact pressure which is out of control.
Description
Technical field
The present invention relates to super lossless sound detection technical field, more particularly to a kind of ultrasound examination shown with pressure is with directly
Probe.
Background technology
At present both at home and abroad the normal probe used by ultrasound detection does not enter to the pressure size that probe is applied on workpiece for measurement
Row detection and control.By to normal probe in the different pressure of surface of the work it is demonstrated experimentally that defect waves are with being applied to work to be measured
The increase of pressure on part and rise.When detection person's hand hold transducer detects workpiece, the power being applied on probe can cause when different
The change of echo amplitude.Analyzing difference of exerting oneself when reason is popped one's head in mainly due to testing staff's hand pressure can affect probe and workpiece table
The coupling effect in face.If the flatness of surface of the work, roughness, couplant meet detection required, it is applied on workpiece for measurement
Pressure it is constant, then flaw echo constant height.Therefore when different detection persons carries out size assessment to same defect, apply
The different height that may result in flaw echo of pressure size on probe is inconsistent, and final result is that different detection persons comment
Different flaw sizes are made, the error of determining defects is caused.
The content of the invention
When the present invention is detected for non-destructive ultrasonic in prior art, probe and the contact of surface of the work cannot monitor and
A kind of test error for causing, there is provided ultrasound examination normal probe shown with pressure, in order in monitoring and test probe with
The contact of surface of the work.
The object of the present invention is achieved like this, a kind of ultrasound examination normal probe shown with pressure, including probe,
The probe periphery is provided with the jack for being easy to wire to connect, it is characterised in that the probe test lead is provided with pressure sensor,
The pressure sensor is used for the contact of measuring probe contact surface and tested portion faces, and the probe is back to test lead
The other end is provided with display screen, and the converted device of the pressure sensor is connected with display screen, and the display screen is used to show that pressure is passed
The pressure value of sensor.
When non-destructive ultrasonic detection is carried out with normal probe with the ultrasound examination that pressure shows using the present invention.Hand-held straight spy
The operating personnel of head, can carry out engaged test, probe and work on side range estimation monitoring display screen with side hand hold transducer in surface of the work
Part surface contact pressure, with keep test when contact in allowed limits, so as to avoid because of the out of control of contact
The measured deviation of generation.
To prevent during test, contact is excessive, and the output end Jing comparator of the pressure sensor is connected with alarm,
When the pressure value of pressure sensor is beyond the maximum for allowing, comparator sends signal, and alarm pipes prompting, to point out to grasp
Make personnel and adjust the contact that probe applies surface of the work.
For ease of the installation of pressure sensor, the pressure sensor is bonding by seccotine with probe test lead.
Description of the drawings
Fig. 1 is the ultrasound examination normal probe shown with pressure of the present invention.
Wherein, 1 display screen；2 jacks；3 probes；4 test leads；5 pressure sensors.
Specific embodiment
As shown in figure 1, for the present invention the ultrasound examination normal probe shown with pressure, including probe 3, pop one's head in 3 outside
It is provided with the jack 2 for being easy to wire to connect week, probe test lead 4 is provided with pressure sensor 5, and pressure sensor 5 is used to measure to be visited
The contact of head contact surface and tested portion faces, the other end popped one's head in back to test lead 4 is provided with display screen 1, pressure sensing
The converted device of device 5 is connected with display screen 1, and display screen is used to show the pressure value of pressure sensor.To prevent contact pressure during test
Power is excessive, and the output end Jing comparator of pressure sensor 5 is connected with alarm, when the pressure value of pressure sensor 5 is beyond permission
Maximum when, comparator sends signal, and alarm pipes prompting, and to point out operating personnel to adjust probe surface of the work is applied
Contact, a diameter of 24mm of the test lead of general such normal probe, the maximum pressure value of permission during test is 5-
8N.In addition, for ease of the installation of pressure sensor 5, pressure sensor 5 is bonding by seccotine with the test lead 4 of probe.
When non-destructive ultrasonic detection is carried out with normal probe with the ultrasound examination that pressure shows using the present invention.Hand-held normal probe
Operating personnel, can carry out engaged test, probe and workpiece table on side range estimation monitoring display screen with side hand hold transducer in surface of the work
Surface contact pressure, with keep test when contact in allowed limits, so as to avoid producing because of the out of control of contact
Measured deviation.
