Ultrasonic wave assisted positioning method for eye position

Abstract

This invention discloses an ultrasonic-assisted method for locating the position of an eyelet, comprising the following five steps. This ultrasonic-assisted method for locating the position of an eyelet utilizes the ultrasonic pulse reflection method. Ultrasonic waves are emitted from the probe of an ultrasonic testing instrument and enter the main steel plate material. By moving the probe, the location of the eyelet, which was previously tapped, is located. The shape of the reflected wave is used to read the specific reflection point information displayed on the instrument, determining the horizontal distance between the eyelet location and the probe edge. Using specialized tooling, a line segment is created. The eyelet location is then precisely located again, and another line segment is created. The intersection of the two line segments is the eyelet location. This method is particularly suitable for steel structure manufacturing units such as shipbuilding companies, effectively controlling the accuracy of the structure's reverse alignment, ensuring that the stress points are at strong structural locations, guaranteeing the safety of the steel structure, and improving product quality. It has advantages such as high practicality, durability, and ease of disassembly and relocation during testing.

Description

Technical Field

[0001] This invention relates to the field of nondestructive testing technology, specifically to an ultrasonic-assisted method for locating the position of a convex eye. Background Technology

[0002] In fitter work and mechanical drilling, marking is often required. To prevent the marked lines from being erased, small holes are drilled at certain intervals along the marked lines as markers. This punch used for marking is called a center punch. Because the hole is punched with a center punch, this positioning hole is called a center punch. Drilling is done using an electronic ruler for positioning, and a center drill and drill bit can accurately drill the hole in the correct position. Cross-shaped welded joints with fillet welds are common in shipbuilding. In addition to welding quality requirements, there are strict requirements for the precision of the assembly of the upper and lower plates. The reasonable control of the assembly precision of the upper and lower plates during on-site construction, and whether the assembly meets the design requirements, is generally achieved by drilling a center punch on one side. After the punch hole is measured by the precision department, the data is reported to the shipowner and ship inspection department. However, in actual operation, the shipowner sometimes doubts the data and often requests ultrasonic testing to assist in the positioning and detection of the punch hole. During assembly, in order to avoid the shearing force caused by the misalignment of the upper and lower plates, which would bring huge safety hazards to the structure, the upper and lower plates are required to have high precision. The accuracy of ultrasonic testing in detecting the position of the punch hole directly affects the important basis for the construction department to judge whether the assembly precision of the upper and lower plates meets the requirements. Pulse ultrasonic reflection detection, through the interaction of the sound beam with the target body, causes the propagation direction to be reflected and received by the detection equipment, which then displays relevant information.

[0003] Since the ultrasonic wave detector itself is a cone, when the beam scans the cone, the distance from the front end of the probe is usually measured when the highest wave is on the screen as the position of the ultrasonic wave detector cone. However, the cone itself has a certain size, and the ultrasonic beam also has a certain degree of diffusion. At this time, the specific position and actual angle of the beam hitting the cone will more or less affect the detection accuracy, thus bringing uncertainty to the detection. It is also difficult to estimate the actual deviation. Summary of the Invention

[0004] The purpose of this invention is to provide an ultrasonic-assisted method for locating the position of an ocean eye, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An ultrasonic-assisted method for locating the position of a sea hole, characterized by comprising the following five steps:

[0007] Step 1: Prepare and adjust the instrument parameters to ensure the accuracy of the displayed information;

[0008] Step 2: Design and manufacture the positioning auxiliary calibration ruler;

[0009] Step 3: The three-point positioning method is used for detection;

[0010] Step 4: The pulsed ultrasound reflection detection is used to determine the eye position of Yangchong's eye;

[0011] Step 5: Verify the eye position center of the detected Yangchong eye.

[0012] Furthermore, the ultrasonic flaw detection equipment to be used is prepared according to the needs of the test, and a display device that matches the ultrasonic flaw detection equipment is debugged to ensure that the information displayed by the ultrasonic flaw detection equipment and the instrument display device is accurate before the test, thereby reducing the test error and improving the accuracy of the test.

[0013] Furthermore, based on the installation location of the ultrasonic flaw detector, a positioning auxiliary calibration ruler is designed and manufactured using the ultrasonic flaw detector as a reference. This allows the calibration ruler to align with the projection angle of the ultrasonic flaw detector, thereby reducing detection errors. After testing, the auxiliary calibration ruler facilitates more convenient line marking and positioning, effectively reducing errors and making position determination easier.

[0014] Furthermore, the ultrasonic flaw detection equipment emits ultrasonic pulses, which are then directionally emitted through the probe to form a sound beam. The sound beam interacts with the target object, causing its propagation direction to be reflected and received by the detection equipment, which then displays relevant information. Utilizing ultrasonic pulse reflection, ultrasonic waves are emitted from the ultrasonic detector probe. By changing different positions, the ultrasonic pulses are reflected again through the probe. The two reflected pulses are then positioned using the display device. A positioning auxiliary calibration ruler is then used to draw a straight line in front of each probe; the intersection of the two lines is the center of the Yangchong eye position, thus enabling the detection and positioning of the Yangchong eye position.

[0015] Furthermore, by utilizing ultrasonic pulse reflection, ultrasonic waves are emitted from the ultrasonic testing instrument probe and enter the main steel plate material. By moving the probe, the location of the pre-struck eye point is located. By reading the shape of the reflected wave, the specific reflection point information displayed by the instrument is read, and the horizontal distance between the eye point and the probe edge is determined. Using a special tool, a line segment is made. Then, with the eye point location as the center and the determined horizontal distance as the radius, the probe is moved to accurately locate the eye point location again. Using the detected eye point location as the center and the determined horizontal distance as the radius, the probe is moved to accurately locate the eye point location again, and another line segment is made. The intersection of the two line segments is the eye point location. Finally, the position of the probe is moved to verify the deviation value of the probe tip from the center.

[0016] Compared with existing technologies, the beneficial effects of this invention are as follows: This ultrasonic-assisted positioning method for the location of the eyelet utilizes the ultrasonic pulse reflection method. Ultrasonic waves are emitted from the probe of an ultrasonic testing instrument and enter the main steel plate material. By moving the probe, the location of the eyelet, which was previously struck, is found. The specific reflection point information displayed on the instrument is read based on the shape of the reflected wave, determining the horizontal distance between the eyelet location and the probe edge. Using specialized tooling, a line segment is created, and the eyelet location is precisely located again by creating another line segment. The intersection of the two line segments is the eyelet location. This method is particularly suitable for steel structure manufacturing units such as shipbuilding companies, effectively controlling the accuracy of the structure's reverse alignment, ensuring that the stress points are at strong structural locations, guaranteeing the safety of the steel structure, and improving product quality. It has advantages such as strong practicality, simple operation, simple and stable structure, resistance to damage, and convenient disassembly and relocation during testing.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-4 The present invention provides an embodiment of an ultrasonic-assisted method for locating the position of a sea hole. This ultrasonic-assisted method for locating the position of a sea hole is characterized by comprising the following five steps:

[0024] Step 1: Prepare and adjust the instrument parameters to ensure the accuracy of the displayed information;

[0025] Step 2: Design and manufacture positioning auxiliary calibration ruler 103;

[0026] Step 3: Use the three-point positioning method for detection;

[0027] Step 4: Pulse ultrasound reflection detection of the eye position of Yangchong eye 101;

[0028] Step 5: Verify the eye position center of the detected Yangchong eye position 101.

[0029] Furthermore, prepare the ultrasonic flaw detection equipment needed for the test according to the requirements, and calibrate the display device that matches the ultrasonic flaw detection equipment to ensure that the information displayed by the ultrasonic flaw detection equipment and the instrument display device is accurate before the test, so as to reduce the test error and improve the accuracy of the test.

[0030] Furthermore, based on the installation location of the ultrasonic flaw detector, a positioning auxiliary calibration ruler 103 is designed and manufactured with the ultrasonic flaw detector as the reference. This allows the calibration ruler 103 to fit the projection angle of the ultrasonic flaw detector, thereby reducing the detection error. After the detection, it is more convenient to perform line marking and positioning based on the auxiliary calibration ruler 103, effectively reducing the error and making the position more convenient to locate, thus reducing the error.

[0031] Furthermore, an ultrasonic flaw detection device emits an ultrasonic pulse, which is then directionally emitted through probe 102 to form a sound beam. The sound beam interacts with the target body, causing its propagation direction to be reflected and received by the detection device, which then displays relevant information. By using ultrasonic pulse reflection, ultrasonic waves are emitted from the ultrasonic detector probe 102. By changing different positions, the ultrasonic pulses are reflected again through probe 102. The pulses from the two reflections are then positioned by the display device. A positioning auxiliary calibration ruler 103 is then used to draw a straight line in front of each probe 102. The intersection of the two lines is the center of the Yangchong eye position 101, which is then detected and positioned.

[0032] Furthermore, by utilizing ultrasonic pulse reflection, ultrasonic waves are emitted from the ultrasonic testing instrument probe 102 and enter the steel plate body 1 material. By moving the probe 102, the position of the pre-struck eye 101 is located. By reading the shape of the reflected wave, the specific reflection point information displayed by the instrument is read, and the horizontal distance between the eye 101 and the edge of the probe 102 is determined. Using a special tooling, a line segment is made. Then, with the eye 101 as the center and the determined horizontal distance as the radius, the probe 102 is moved to accurately locate the eye 101 again. Using the detected eye 101 as the center and the determined horizontal distance as the radius, the probe 102 is moved to accurately locate the eye 101 again, and another line segment is made. The intersection of the two line segments is the position of the eye 101. Then, the position of the probe 102 is moved to verify the deviation value of the probe 102 front end from the center.

[0033] During testing, the ultrasonic flaw detection equipment and display equipment are prepared and debugged according to the testing requirements. Before testing, it is ensured that the information displayed by the ultrasonic flaw detection equipment and the instrument display equipment is accurate, reducing testing errors. A positioning auxiliary calibration ruler 103 is designed and manufactured according to the installation position of the ultrasonic flaw detection equipment, so that the calibration ruler 103 can fit the projection angle of the ultrasonic flaw detection equipment, thereby reducing testing errors. The ultrasonic flaw detection equipment emits ultrasonic pulses, which are directionally emitted through the probe 102. The sound beam interacts with the target object, causing it to reflect in its propagation direction and be received by the testing equipment, which then displays relevant information. Ultrasonic waves are emitted by the ultrasonic testing instrument probe 102. By moving the probe 102, the target object is located where it was previously struck. The position of the eye point 101 is determined by reading the specific reflection point information displayed by the instrument through the shape of the reflected wave. The horizontal distance between the eye point 101 and the edge of the probe 102 is determined. Using a special tool, a line segment is made. Then, with the eye point 101 as the center and the determined horizontal distance as the radius, the probe 102 is moved to accurately find the eye point 101 again. Using the detected eye point 101 as the center and the determined horizontal distance as the radius, the probe 102 is moved to accurately find the eye point 101 again. Another line segment is made. The intersection of the two line segments is the position of the eye point 101. Then, the position of the probe 102 is moved to verify the deviation value of the front end of the probe 102 from the center.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
