Description

Technical Field

[0001] This utility model belongs to the technical field of ultrasonic testing equipment, specifically relating to an online center adjustment structure for an ultrasonic probe. Background Technology

[0002] Ultrasonic flaw detection systems utilize phased array instruments to control the excitation time and sequence of multiple crystals in an ultrasonic probe, thereby deflecting and focusing the sound beam to obtain information about internal defects. The ultrasonic probe is a key component of the ultrasonic testing system. However, in practical use, factors such as installation errors, wear and tear from long-term use, and external environmental vibrations can easily cause the center position of multiple ultrasonic probes to shift, leading to inaccurate test results. Furthermore, most existing methods for adjusting the center of the ultrasonic probe require removing it from the equipment and manually adjusting it offline. This method is not only cumbersome and inefficient but also makes it difficult to achieve high-precision adjustments.

[0003] Therefore, there is an urgent need for an online center adjustment structure for ultrasonic probes that can achieve online adjustment of the probe center, and has high adjustment accuracy, simple operation, and good stability. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an online center adjustment structure for ultrasonic probes, so as to solve the problems of cumbersome operation, low efficiency and poor accuracy of existing ultrasonic probe center adjustment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a center-online adjustment structure for an ultrasonic probe, comprising a probe mounting plate for mounting an ultrasonic probe and a U-shaped frame surrounding the probe mounting plate.

[0006] The first slide block is slidably connected to the U-shaped frame along the X-axis direction, and a first fine-tuning screw is rotatably connected to the first slide block along the Y-axis direction. One end of the first fine-tuning screw passes through the first slide block and is threadedly connected to the probe mounting plate.

[0007] A second fine-tuning screw is rotatably connected to the U-shaped frame along the Y-axis. The first fine-tuning screw has a positive thread and a negative thread. A first lug block is threaded to the positive thread, and a second lug block is threaded to the negative thread. A second slide block is slidably connected to the probe mounting plate along the Y-axis. A first hinge rod and a second hinge rod are provided on the second slide block. The two ends of the first hinge rod are hinged to the second slide block and the first lug block, respectively. The two ends of the second hinge rod are hinged to the second slide block and the second lug block, respectively.

[0008] Optionally, the bolt heads on the first and second fine-tuning screws are positioned on the same side of the spiral frame.

[0009] Optionally, the probe mounting plate is provided with a plurality of threaded holes for mounting the ultrasonic probe.

[0010] Optionally, the first hinge rod and the second hinge rod are of the same length.

[0011] Optionally, the two sides of the spiral frame are detachably connected with perforated cover plates by bolts.

[0012] Optionally, a first limiting bearing is sleeved on the outer periphery of the first fine-tuning screw, and the shaft hole on the first limiting bearing is interference-fitted with the outer wall of the first fine-tuning screw, and the outer wall of the first limiting bearing is interference-fitted with the inner wall of the through hole on the first slide for the first fine-tuning screw to pass through.

[0013] Optionally, a second limiting bearing is sleeved on the outer periphery of the second fine-tuning screw, and the shaft hole on the second limiting bearing is interference-fitted with the outer wall of the second fine-tuning screw, and the outer wall of the second limiting bearing is interference-fitted with the inner wall of the through hole on the U-shaped frame for through which the second fine-tuning screw passes.

[0014] Optionally, a lifting handle is provided on one side of the spiral frame.

[0015] Optionally, a first locking bolt that can abut against the outer periphery of the first fine-tuning screw is threaded through and connected to the first slide block, and a second locking bolt that can engage with the outer periphery of the second fine-tuning screw is threaded through and connected to the U-shaped frame.

[0016] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: by twisting the first fine-tuning screw to drive the probe mounting plate to move along the Y-axis, and by twisting the second fine-tuning screw to drive the probe mounting plate to move along the X-axis, the detection center can be quickly and accurately adjusted in a fixed plane. Moreover, the entire process does not require disassembling the ultrasonic probe, and the adjustment can be performed while the ultrasonic probe is online, which simplifies the operation steps and effectively improves the adjustment efficiency.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0026] It should be noted that if directional indicators (such as up, down, bottom, top, etc.) are involved in this embodiment, these directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances. Example 1

[0027] like Figures 1-6As shown, an online center adjustment structure for an ultrasound probe includes a probe mounting plate 1 for mounting the ultrasound probe and a U-shaped frame 2 surrounding the probe mounting plate 1. A first slide block 3 is slidably connected to the U-shaped frame 2 along the X-axis. The first slide block 3 does not move along the Y-axis, and a first fine-tuning screw 4, arranged along the Y-axis, is passed through and rotatably connected to the first slide block 3. One end of the first fine-tuning screw 4, passing through the first slide block 3, is threadedly connected to the probe mounting plate 1. Therefore, by twisting the first fine-tuning screw 4 to adjust the threaded connection depth on the probe mounting plate 1, the probe mounting plate 1 is driven to move along the Y-axis. A second fine-tuning screw 5, arranged along the Y-axis, is rotatably connected to the U-shaped frame 2. The rotation centerline of the second fine-tuning screw 5 is parallel to the Y-axis, and the second fine-tuning screw 5 cannot move along either the Y-axis or the X-axis. Meanwhile, the first fine-tuning screw 4 is provided with a positive thread and a negative thread (the thread diameter and pitch of the positive thread and the negative thread are equal). The positive thread is threaded to a first lug block 6, and the negative thread is threaded to a second lug block 7. The probe mounting plate 1 is slidably connected to a second slide block 8 along the Y-axis, meaning that the second slider cannot rotate relative to the probe mounting plate 1. At the same time, since the second slide block 8 is provided with a first hinge rod 9 and a second hinge rod 10, and the two ends of the first hinge rod 9 are hinged to the second slide block 8 and the first lug block 6 respectively, and the two ends of the second hinge rod 10 are hinged to the second slide block 8 and the second lug block 7 respectively, the first lug block 6 and the second lug block 7 cannot rotate relative to the second fine-tuning screw 5, but can only move along the axial direction of the second fine-tuning screw 5. When the second fine-tuning screw 5 is twisted, the first ear block 6 and the second ear block 7 can move towards or away from each other along the axial direction of the second fine-tuning screw 5, so as to change the included angle between the first ear block 6 and the second ear block 7, thereby driving the probe mounting plate 1 to move along the X-axis.

[0028] It should also be noted that the Y-axis and X-axis mentioned above correspond to the Y-axis and X-axis in a Cartesian coordinate system, that is, the Y-axis and X-axis in this technical solution are perpendicular to each other. The first slide block 3, which is slidably connected to the U-shaped frame 2 along the X-axis, and the second slide block 8, which is slidably connected to the probe mounting plate 1 along the Y-axis, can utilize one or more of the following sliding connection methods commonly used in the prior art: guide rail-slider sliding structure, dovetail groove sliding structure, rectangular / triangular sliding structure, etc., specifically as follows: Figure 4 , Figure 5 As shown, the dovetail groove sliding structure is used between the spiral frame 2 and the first slide 3, and between the probe mounting plate 1 and the second slide 8, that is, the spiral frame 2 and the first slide 3, and the probe mounting plate 1 and the second slide 8 are fitted with a clearance.

[0029] In practical use, multiple sets of ultrasonic probes can be fixedly mounted on the probe mounting plate 1. Specifically, the probe mounting plate 1 has several threaded holes 101 for mounting the ultrasonic probes, allowing them to be fixed to the plate with bolts. It is important to note that the detection center formed by the multiple sets of ultrasonic probes fixedly mounted on the probe mounting plate 1 is fixed relative to the plate. The U-shaped frame 2 can be fixed to the ultrasonic flaw detection equipment using various connection methods such as bolt tightening, welding, and fastening. Therefore, the operator can adjust the detection center position by turning the first fine-tuning screw 4 to move the probe mounting plate 1 along the Y-axis and by turning the second fine-tuning screw 5 to move it along the X-axis. This entire process can be performed while the ultrasonic probe is online, simplifying the operation and improving adjustment efficiency. Furthermore, since the accuracy of the probe mounting plate 1's movement along the Y and X axes is linearly or curvilinearly related to the pitch and number of rotations of the first and second fine-tuning screws 4 and 5, the accuracy of the detection center position adjustment can be greatly improved.

[0030] In the above-mentioned case, the bolt heads on the first fine-tuning screw 4 and the second fine-tuning screw 5 are positioned on the same side of the loop frame 2, as shown. Figure 1 As shown, the first fine-tuning screw 4 and the second fine-tuning screw 5 are arranged to facilitate the operator's rotation. When the operator installs the spiral frame 2 on the ultrasonic flaw detection equipment, the first fine-tuning screw 4 and the second fine-tuning screw 5 are exposed to the maximum extent within the operator's operability range.

[0031] Meanwhile, when the first hinge rod 9 and the second hinge rod 10 used above are of different lengths, the second slide block 8 will slide relative to the probe mounting plate 1 as the first ear block 6 and the second ear block 7 move toward or away from each other; while when the first hinge rod 9 and the second hinge rod 10 are of equal length, the second slide block 8 will not slide relative to the probe mounting plate 1 as the first ear block 6 and the second ear block 7 move toward or away from each other.

[0032] And in this embodiment, such as Figure 1 , Figure 6 As shown, a first locking bolt 15, which abuts against the outer periphery of the first fine-tuning screw 4, is threaded through and connected to the first slide block 3. A second locking bolt 16, which abuts against the outer periphery of the second fine-tuning screw 5, is threaded through and connected to the U-shaped frame 2. That is, by loosening the first locking bolt 15 and the second locking bolt 16, the locking of the first fine-tuning screw 4 and the second fine-tuning screw 5 can be released. Conversely, by tightening the first locking bolt 15 and the second locking bolt 16, the positions of the first fine-tuning screw 4 and the second fine-tuning screw 5 can be locked. Simultaneously, the self-locking properties of the threaded connection between the first fine-tuning screw 4 and the first slide block 3, and the self-locking properties of the threaded connection between the second fine-tuning screw 5 and the U-shaped frame 2, effectively ensure the stability of the detection center position. Example 2

[0033] like Figures 1-6 As shown, based on Embodiment 1, the two sides of the U-shaped frame 2 are detachably connected with hollow cover plates 11 by bolts to cover the first fine-tuning screw 4, the second fine-tuning screw 5, the first ear block 6, the second ear block 7, the first hinge rod 9, the second hinge rod 10, the second slide block 8 and other structures, to prevent the lines, pipes and other structures in the ultrasonic flaw detection equipment from accidentally entering.

[0034] Furthermore, as shown in 4, a first limiting bearing 13 is sleeved on the outer periphery of the first fine-tuning screw 4, and the shaft hole on the first limiting bearing 13 is interference-fitted with the outer wall of the first fine-tuning screw 4. The outer wall on the first limiting bearing 13 is interference-fitted with the inner wall of the through hole on the first slide block 3 for passing through the first fine-tuning screw 4, so as to ensure the installation accuracy of the first fine-tuning screw 4.

[0035] Similarly, to ensure the installation accuracy of the second fine-tuning screw 5, such as Figure 3 As shown, a second limiting bearing 14 is sleeved on the outer periphery of the second fine-tuning screw 5, and the shaft hole on the second limiting bearing 14 is interference-fitted with the outer wall of the second fine-tuning screw 5. The outer wall of the second limiting bearing 14 is interference-fitted with the inner wall of the through hole on the U-shaped frame 2 for the second fine-tuning screw 5 to pass through.

[0036] In this embodiment, a lifting handle 12 is provided on one side of the spiral frame 2 to facilitate the operator to disassemble and install the spiral frame 2.

[0037] Working principle: First, multiple ultrasonic probes can be fixedly mounted on the probe mounting plate 1. The detection center formed by these multiple ultrasonic probes is fixed relative to the probe mounting plate 1. The U-shaped frame 2 can be fixedly mounted on the ultrasonic flaw detection equipment. The operator can drive the probe mounting plate 1 to move along the Y-axis by twisting the first fine-tuning screw 4 and to move it along the X-axis by twisting the second fine-tuning screw 5, thereby quickly and accurately adjusting the position of the detection center online.

[0038] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
