Description

Technical Field

[0001] The utility model relates to a thickness detection device, in particular to an electromagnetic ultrasonic thickness measuring device for accurately detecting thickness. Background Art

[0002] Electromagnetic ultrasonic thickness gauges are primarily used to measure the thickness of various metal and non-metal materials (such as ships, bridges, and pipelines). They are particularly suitable for applications where access is difficult or magnetic particle testing is inconvenient. The device generates ultrasonic pulses through electromagnetic field excitation, and then uses a transducer to receive the reflected ultrasonic waves to calculate the thickness. These gauges offer high accuracy, non-contact measurement, and a compact design, making them commonly used for thickness testing of both metal and non-metal materials.

[0003] Currently, most detection probes used on electromagnetic ultrasonic thickness measuring devices are of permanent magnetic structure. When in use, the probe is attached to the surface of the test sample for fixation, and then the data cable of the probe is inserted into the detection instrument of the device to complete the assembly of the thickness measuring device, and the detection instrument is operated to perform thickness detection.

[0004] However, when using this type of electromagnetic ultrasonic thickness measurement device, the probe is often suddenly attracted by magnetic materials, which can easily cause the probe to collide and damage the probe, affecting the detection precision of the device and making it inconvenient to use in automated detection lines. Based on the above reasons, it is necessary to design an electromagnetic ultrasonic thickness measurement device with a probe protection structure that can be accurately applied to automated detection lines. Utility Model Content

[0005] In view of the above problems existing in the prior art, the purpose of the present invention is to provide an electromagnetic ultrasonic thickness measuring device for precise thickness detection, which realizes the protection treatment of the probe in the electromagnetic ultrasonic thickness measuring device so that it can be precisely applied to the detection purpose of the automated detection line.

[0006] To achieve the above purpose, the technical solution of this utility model is as follows:

[0007] An electromagnetic ultrasonic thickness measuring device for precise thickness detection includes a detector body, a signal line is provided on the detector body, a probe is provided at one end of the signal line, a buffer seat is provided on the outer surface of the probe, and buffer components are provided on both sides of the buffer seat. The buffer components include a support rod slidably connected to the buffer seat, a spring sleeved on one end of the support rod and connected to the buffer seat, and a damping sleeve provided in the middle of the spring. The lower ends of the two buffer components are provided with the same electromagnetic ring for all-round protection of the detection structure in the thickness measuring device.

[0008] Preferably, the buffer seat is provided with a slot that cooperates with the probe, and a snap ring is provided at the edge of the slot.

[0009] Preferably, a rubber sleeve is provided on the outer side of the buffer seat, and the buffer assembly is distributed vertically to the buffer seat.

[0010] Preferably, an anti-slip sleeve cooperating with the support rod is provided through the buffer seat, the longitudinal section of the anti-slip sleeve is an "I"-shaped structure, and the anti-slip sleeve is made of rubber material.

[0011] Preferably, the other ends of the two support rods are provided with the same gripping rod, the same threaded sleeve is sleeved between the support rods and the gripping rods, and the outer sides of both ends of the support rods and the gripping rods are provided with threaded grooves that cooperate with the threaded sleeves.

[0012] Preferably, a connecting wire connected to the probe is provided on the outer side of the electromagnetic ring, and a spiral portion is provided on the connecting wire.

[0013] Preferably, a magnetic control unit is provided on the detector body, and a control button is provided on one side of the magnetic control unit.

[0014] Compared to existing technologies, the electromagnetic ultrasonic thickness gauge provided by this utility model provides precise thickness detection by protecting the detection probe within the device, thereby increasing the device's detection precision and flexibility. Specifically, the combination of a buffer seat, a buffer assembly, and an electromagnetic ring on the probe's exterior creates a protective space outside the probe, providing horizontal and vertical shock absorption protection for the probe. This protects the probe from direct contact with external objects, preventing collision damage, and ultimately improving the accuracy of the thickness gauge's detection data, enabling precise object detection.

[0015] In addition, by setting the electromagnetic ring and the grip rod on the two buffer components, the device can use the power switch of the electromagnetic ring to adsorb on the detection object. Then, by using the grip rod, the detection personnel can flexibly move the probe position to detect different positions of the object, facilitate the detection operation of the automated detection line, increase the detection convenience of the device, and is very beneficial for the precise detection of the thickness measuring device.

[0016] It should be understood that the general description and detailed description herein are exemplary and explanatory only and are not intended to restrict the present disclosure.

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure more clear, the embodiments of the present disclosure are described in more detail below in conjunction with the drawings of the embodiments. Note: The described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0026] As attached Figure 1 and attached Figure 2As shown, an embodiment of the present invention provides an electromagnetic ultrasonic thickness gauge for precise thickness measurement, used for measuring the thickness of a specimen. The electromagnetic ultrasonic thickness gauge comprises a detector body 1, a signal line 11, and a probe 12, with the probe 12 forming the device's detection structure. When the device is in use, the signal line 11 of the probe 12 is connected to the detector body 1, and the probe 12 is placed, either in contact with or loosely attached, on the object to be measured. The thickness of the object is measured using existing electromagnetic ultrasonic thickness measurement technology. The electromagnetic ultrasonic thickness gauge utilizes a time-space complementary algorithm for detection. Its application in thickness detectors primarily improves detection accuracy and efficiency by combining time-space information. This algorithm utilizes the complementary use of spatial information (e.g., cross-sectional geometry) and temporal information (e.g., ultrasonic wave propagation time) of the measured object to achieve precise thickness measurement. Specifically, the application of the time-space complementary algorithm in thickness detectors involves the following steps: 1. Data acquisition: The sensor collects spatial and temporal information of the measured object. 2. Information fusion: The collected spatial and temporal information is fused using the time-space complementary algorithm to extract useful information. 3. Depth Calculation: By calculating time information and combining it with parameters such as the speed of sound of the object material, the thickness of the object is calculated. 4. Calibration and Optimization: Calibrate the calculated results to improve the accuracy and stability of the measurement, thereby improving the precision of the thickness measurement device's detection data.

[0027] The thickness measuring device also includes: a buffer seat 2 sleeved on the outside of the probe 12, and vertically distributed buffer components 3 are set on both sides of the buffer seat 2; and the buffer component 3 includes a support rod 31 slidingly connected to the buffer seat 2, a spring 32 sleeved on one end of the support rod 31 and connected to the buffer seat 2, and a damping sleeve 33 set in the middle of the spring 32. The lower ends of the two buffer components 3 are provided with the same electromagnetic ring 4 for all-round protection of the outside of the probe 12. By sleeved on the outside of the probe 12, the peripheral side of the probe 12 can be protected, and the protective structure of the probe 12 in the horizontal direction can be increased; then, the buffer components 3 are set through both sides of the buffer seat 2, and the buffer components 3 and the buffer seat 2 are perpendicular to each other, so as to facilitate the parallel setting of the probe 12 and the surface of the detection object, avoid the deviation of the measurement direction, increase the accuracy of the detection data, and ensure the precision of the detection data. In addition, the buffer assembly 3 includes a support rod 31 that is slidably connected to the buffer seat 2. One end of the support rod 31 is sleeved with a spring 32 connected to the buffer seat 2. Both ends of the spring 32 are provided with rubber rings for use in conjunction with each other. Then, a damping sleeve 33 is provided in the middle of the spring 32. The damping sleeve 33 is sleeved on the outside of the support rod 31 to facilitate the vertical buffering of the probe 12. The same electromagnetic ring 4 is then provided between the ends of the two buffer assemblies 3. When the probe 12 is used on an automated detection line, the buffer seat 2 and the buffer assembly 3 are used in conjunction to construct a protective space outside the probe 12, protecting the probe 12 inside, facilitating the separation and buffering of the magnetic attraction between the probe 12 and the external magnetic object, achieving horizontal and vertical buffering of the outside of the probe 12, avoiding direct contact between the probe 12 and the magnetic object, improving the collision and damage of the probe 12, and ensuring the detection precision of the device. By turning on the power switch of the electromagnetic ring 4, the probe 12 is conveniently magnetically attracted to the detection object, which is convenient for the detection personnel to operate.

[0028] In order to facilitate the connection between the buffer seat 2 and the probe 12, as shown in FIG. Figure 3 As shown, in some embodiments, the probe 12 can be clamped to the buffer seat 2, and a clamping groove 21 that cooperates with the probe 12 is opened on the buffer seat 2. A clamping ring 22 for clamping the probe 12 is provided at the edge of the clamping groove 21, so that the probe 12 can be easily removed from the buffer seat 2, and the probe 12 can be repaired or replaced, thereby increasing the detachability of the probe 12 and the buffer seat 2 and improving the detection accuracy of the thickness measuring device.

[0029] In order to better protect and support the periphery of the probe 12, as shown in FIG. Figure 4As shown, the buffer seat 2 can be made of elastic material, or a rubber sleeve can be provided on the outside of the buffer seat 2 to increase the elasticity of the buffer seat 2 and reduce the impact force between the object and the buffer seat 2. In addition, the buffer assembly 3 is arranged vertically on the buffer seat 2. The vertical arrangement of the buffer seat 2 and the buffer assembly 3 facilitates the buffer assembly 3 to surround the probe 12 inside, providing external support for the probe 12 in the vertical direction, reducing the influence of external magnetic objects on the probe 12, achieving protection for the probe 12, and facilitating the parallel placement of the probe 12 on the surface of the test object, preventing the probe 12 from deflecting, thereby improving the detection accuracy of the thickness measuring device.

[0030] In some embodiments, in order to better connect the vertical sliding of the buffer seat 2 and the support rod 31 in the buffer assembly 3, as shown in FIG. Figure 4 As shown, an anti-slip sleeve 311 that cooperates with the support rod 31 can be set through the buffer seat 2. The longitudinal section of the anti-slip sleeve 311 is an "I"-shaped structure, and the anti-slip sleeve 311 is made of rubber material, which facilitates the upper and lower ends of the anti-slip sleeve 311 to fit with the upper and lower surfaces of the buffer seat 2, thereby increasing the connection firmness between the anti-slip sleeve 311 and the buffer seat 2; the middle part of the anti-slip sleeve 311 passes through the support rod 31, which facilitates the movement of the buffer seat 2 on the support rod 31, and performs shock-absorbing treatment on the connection between the buffer seat 2 and the support rod 31, thereby improving the support effect of the buffer assembly 3 on the probe 12.

[0031] In order to facilitate the use of the probe 12 on the automated detection line, Figure 2 and 3 As shown, a handheld structure can be added to the probe 12. As shown in the figure, a same grip 314 can be set at the other end of the two support rods 31 for connection, forming a U-shaped structure, and the grip 314 and the electromagnetic ring 4 are respectively located on both sides of the buffer seat 2. The grip 314 and the buffer seat 2 are used for the detection personnel to pass their hands, and the grip 314 is used for the detection personnel to hold and use. In addition, this structure can be set as a detachable structure with the support rod 31 in the buffer assembly 3. By setting the same threaded sleeve 313 between the support rod 31 and the grip 314, the outer sides of the two ends of the support rod 31 and the grip 314 are provided with a threaded groove 312 that cooperates with the threaded sleeve 313, which facilitates the tightening of the connection between the support rod 31 and the grip 314 through the threaded sleeve 313, and the grip 314 is connected to the support rod 31 for use, which facilitates the disassembly of the grip 314 and the replacement of the probe 12.

[0032] Among them, it is worth mentioning that Figure 1 and 2As shown, when the electromagnetic ring 4 is in use, its outer connecting line 41 can be connected to the existing probe 12 of the thickness measuring device, which is convenient for the power-on use of the electromagnetic ring 4. The magnetic characteristics of the existing electromagnet when powered on are applied, so that the electromagnetic ring 4 can be magnetically adsorbed on the detection object after being powered on, which provides convenience for the fit detection between the device and the detection object; similarly, the electromagnetic ring 4 can also be used when the power is off. The electromagnetic ring 4 and the buffer assembly 3 can set the probe 12 parallel to the outer surface of the detection object, which provides convenience for the non-fit detection of the device. In order to facilitate the buffering use of the buffer seat 2 on the buffer assembly, a spiral portion 411 can be set in the middle of the connecting line 41 to shorten the length of the connecting line 41 and avoid damage to the connecting line 41. In order to facilitate the adsorption and fixation of the probe 12 on different magnetic materials, a magnetic control unit 42 can also be set on the detector body 1. By applying the magnetic control technology of the existing electromagnet, the current in the electromagnetic ring 4 can be adjusted to change the magnetic force of the electromagnetic ring 4, thereby increasing its wide application.

[0033] Of course, the above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
