Abstract
The utility model is related to a kind of ultrasound examination normal probe shown with pressure in non-destructive ultrasonic detection technique field, including probe, the probe periphery is provided with the jack for being easy to wire to connect, it is characterized 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, the probe is provided with display screen back to the other end of test lead, the converted device of pressure sensor is connected with display screen, and the display screen is used to show the pressure value of pressure sensor.Using it is of the present utility model with the ultrasound examination that pressure shows carried out with normal probe non-destructive ultrasonic detect when.The operating personnel of hand-held normal probe, engaged test can be carried out in workpiece surface with side hand hold transducer, side range estimation monitoring display screen on probe with workpiece surface contact, with keep test when contact in allowed limits, so as to the measured deviation for avoiding being produced by the out of control of contact.
Description
Technical field
The utility model is related to super lossless sound detection technical field, more particularly to a kind of ultrasound examination shown with pressure
Use normal probe.
Background technology
Normal probe both at home and abroad used by ultrasound detection does not enter to the pressure size that probe is applied on workpiece for measurement at present
Row detection and control.By to normal probe in the different pressure of workpiece surface 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.Analysis reason exerts oneself when pop one's head in mainly due to testing staff's hand pressure different to influence probe and workpiece table
The coupling effect in face.If the flatness of workpiece surface, 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.
Utility model content
When the utility model is detected for non-destructive ultrasonic in the prior art, probe cannot be supervised with the contact of workpiece surface
The test error surveyed and cause, there is provided a kind of ultrasound examination normal probe shown with pressure, in order to be visited in monitoring and test
Head and the contact of workpiece surface.
The purpose of this utility model is achieved in that 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 biography
Sensor, the pressure sensor is used for the contact of measuring probe contact surface and tested portion faces, and the probe is back to survey
The other end for trying end is provided with display screen, and the converted device of pressure sensor is connected with display screen, and the display screen is used to show
The pressure value of pressure sensor.
Using it is of the present utility model with the ultrasound examination that pressure shows carried out with normal probe non-destructive ultrasonic detect when.It is hand-held
The operating personnel of normal probe, can carry out engaged test with side hand hold transducer in workpiece surface, be popped one's head on side range estimation monitoring display screen
With workpiece surface contact, with keep test when contact in allowed limits, so as to avoid the mistake because of contact
The measured deviation controlled and produce.
To prevent during test, contact is excessive, and the output end of the pressure sensor is connected with alarm through comparator,
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 the contact that personnel's regulation probe applies workpiece surface.
For ease of the installation of pressure sensor, the pressure sensor passes through strength glue sticking with probe test lead.
Brief description of the drawings
Fig. 1 is the ultrasound examination normal probe shown with pressure of the present utility model.
Wherein, 1 display screen；2 jacks；3 probes；4 test leads；5 pressure sensors.
Specific embodiment
As shown in figure 1, be the ultrasound examination normal probe shown with pressure of the present utility model, including probe 3, probe
3 peripheries are provided with the jack 2 for being easy to wire to connect, and probe test lead 4 is provided with pressure sensor 5, and pressure sensor 5 is used to measure
The contact of probe contacts face and tested portion faces, probe is provided with display screen 1 back to the other end of test lead 4, and pressure is passed
The converted device of sensor 5 is connected with display screen 1, and display screen is used to show the pressure value of pressure sensor.To prevent being contacted during test
Pressure is excessive, and the output end of pressure sensor 5 is connected with alarm through comparator, when the pressure value of pressure sensor 5 is beyond fair
During maximum perhaps, comparator sends signal, and alarm is piped prompting, and workpiece surface is applied to point out operating personnel to adjust probe
Contact, a diameter of 24mm of the test lead of general such normal probe, the maximum pressure value of permission during test for 5-
8N.In addition, for ease of the installation of pressure sensor 5, pressure sensor 5 passes through strength glue sticking with the test lead 4 of probe.
Using it is of the present utility model with the ultrasound examination that pressure shows carried out with normal probe non-destructive ultrasonic detect when.It is hand-held
The operating personnel of normal probe, can carry out engaged test with side hand hold transducer in workpiece surface, be popped one's head on side range estimation monitoring display screen
With workpiece surface contact, with keep test when contact in allowed limits, so as to avoid the mistake because of contact
The measured deviation controlled and produce.
