Description

Technical Field

[0001] This utility model belongs to the field of ultrasonic testing instrument technology, specifically relating to an axial stress ultrasonic testing instrument. Background Technology

[0002] An ultrasonic testing instrument is a device that uses ultra-high frequency sound waves for detection and analysis. Sound waves are the mechanical vibration state of an object or a form of energy propagation. Vibration refers to the back-and-forth motion of a particle around its equilibrium position. Ultrasonic waves usually propagate in an elastic medium as longitudinal waves. It is a form of energy propagation, characterized by high frequency, short wavelength, and good beam and directionality when propagating in a straight line over a certain distance.

[0003] Existing axial stress ultrasonic testing instruments measure the axial stress data of the object being tested by simply contacting or pressing the instrument with the object. During the measurement process, the connection between the two may become loose or even break, which may lead to large errors in the measured data and reduce the detection accuracy of the axial stress ultrasonic testing instrument. Therefore, an axial stress ultrasonic testing instrument is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an axial stress ultrasonic testing instrument to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an axial stress ultrasonic testing instrument, comprising an ultrasonic testing instrument body and a connecting plate. A clamping device is provided on the surface of the connecting plate. The clamping device includes four mounting blocks. Fixing nails are inserted into the interior of each of the four mounting blocks. Connecting rods are fixedly connected to the surfaces of the four mounting blocks respectively. Limiting rings are fixedly connected to the bottoms of the four connecting rods. A trapezoidal groove is formed inside the limiting ring. An adjusting plate is slidably connected to the inner wall of the trapezoidal groove. A storage rod is fixedly connected to the surface of the adjusting plate. A telescopic slide rod is slidably connected inside the storage rod. A clamping rubber block is fixedly connected to the surface of the telescopic slide rod. A spring is fixedly connected to the surface of the clamping rubber block near the telescopic slide rod. An arc-shaped storage plate is fixedly connected to the surface of the adjusting plate. An arc-shaped protective plate is slidably connected inside the arc-shaped storage plate. Multiple positioning holes are formed inside the limiting ring. Positioning fixing rods are inserted into the positioning holes. A connecting slide rod is fixedly connected to the end of the positioning fixing rod away from the limiting ring. A limiting plate is slidably connected to the surface of the connecting slide rod.

[0006] By setting up the above structure, when it is necessary to clamp the stress detector with different test objects to fix them together, the clamping device can be installed on the surface of the connecting plate by fixing pins. This allows the clamping device to be installed between the clamping device and the connecting plate, making it easy to assemble and disassemble. The position of the adjustment plate can be moved and adjusted to the optimal clamping position for the test object according to the shape of different test objects. Then, the test object will be clamped in the clamping ring formed by multiple clamping rubber blocks. The clamping rubber blocks can fit closely with the test object and increase the friction between the two, thereby preventing the test object from slipping during the clamping process. At the same time, it can also improve the stability between the clamping rubber blocks and the test object, thus ensuring that the stress detector can maintain a tight contact connection with the test object. This prevents the test object from easily shaking during the stress detector testing process, affecting the test data, and thus ensuring the detection accuracy of the axial stress ultrasonic detector.

[0007] As a preferred embodiment, the surface of the ultrasonic testing instrument body is provided with a display screen, two control switches, and multiple operation buttons.

[0008] As a preferred embodiment, the top of the ultrasonic testing instrument body is provided with a wiring port, the wiring port is provided with a connecting wire, one end of the connecting wire is fixedly connected to the top of the connecting plate, and the bottom of the connecting plate is provided with a stress testing instrument.

[0009] As a preferred embodiment, the fixing pin is inserted and connected to the connecting plate, one end of the spring is fixedly connected to one end of the storage rod, and the spring is sleeved on the surface of the telescopic slide rod.

[0010] As a preferred embodiment, the arc-shaped storage plate is located above the storage rod, and one end of the arc-shaped protective plate is fixedly connected to the end of the clamping rubber block near the telescopic slide rod.

[0011] As a preferred embodiment, the positioning and fixing rod is inserted and connected to the adjusting plate, and the surface of the limiting plate is fixedly connected to the surface of the limiting ring.

[0012] By setting up an arc-shaped storage plate and an arc-shaped protective plate, which are located above the storage rod, telescopic slide rod, and spring, the arc-shaped protective plate can protect the clamping structure composed of the storage rod, telescopic slide rod, and spring, so that external interference will not directly affect the clamping structure, thereby ensuring the stability of the clamping structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, by setting a fixing nail, an adjusting plate, and clamping rubber blocks, allows for the clamping of a stress detector to different test objects for a fixed connection. The fixing nail allows the clamping device to be mounted on the surface of a connecting plate, facilitating easy assembly and disassembly. The adjusting plate is moved according to the shape of the test object to achieve the optimal clamping position. The test object is then clamped within a clamping ring formed by multiple clamping rubber blocks. The clamping rubber blocks adhere closely to the test object, increasing friction and preventing slippage during clamping. This also improves the stability between the clamping rubber blocks and the test object, ensuring a tight contact between the stress detector and the test object. This prevents the test object from easily shaking during testing, thus ensuring the accuracy of the axial stress ultrasonic detector.

[0015] This invention, by setting an arc-shaped storage plate and an arc-shaped protective plate, which are located above the storage rod, the telescopic slide rod and the spring, can protect the clamping structure composed of the storage rod, the telescopic slide rod and the spring, so that external interference will not directly act on the clamping structure, thereby ensuring the stability of the clamping structure.

A receiving rod 90 is fixedly connected to the surface of the adjusting plate 906. 7. A telescopic slide rod 908 is slidably connected inside the storage rod 907. A clamping rubber block 909 is fixedly connected to the surface of the telescopic slide rod 908. A spring 910 is fixedly connected to the surface of the clamping rubber block 909 near the telescopic slide rod 908. An arc-shaped storage plate 911 is fixedly connected to the surface of the adjusting plate 906. An arc-shaped protective plate 912 is slidably connected inside the arc-shaped storage plate 911. Multiple positioning holes 913 are opened inside the limiting ring 904. A positioning fixing rod 914 is inserted and connected inside the positioning hole 913. A connecting slide rod is fixedly connected to the end of the positioning fixing rod 914 away from the limiting ring 904. The rod 915 is slidably connected to the surface of the sliding rod 915 by a limiting plate 916. By setting a fixing pin 902, an adjusting plate 906, and a clamping rubber block 909, when it is necessary to clamp the stress detector 8 with different test objects to fix them together, the fixing pin 902 can be used to install the clamping device 9 on the surface of the connecting plate 7, thus facilitating the installation and disassembly of the clamping device 9. The position of the adjusting plate 906 is moved according to the shape of different test objects to adjust it to the optimal clamping position for the test object. Afterwards, the test object will be clamped in multiple... Within the clamping ring formed by the clamping rubber block 909, the clamping rubber block 909 can adhere to the object being tested and increase the friction between the two, thereby preventing the object being tested from slipping during the clamping process. At the same time, it can also improve the stability between the clamping rubber block 909 and the object being tested, thus ensuring that the stress detector 8 can maintain a tight contact connection with the object being tested. This prevents the object being tested from easily shaking during the testing process, affecting the test data, and thus ensuring the testing accuracy of the axial stress ultrasonic detector.

[0024] The surface of the ultrasonic detector body 1 is equipped with a display screen 2, two control switches 3, and multiple operation buttons 4.

[0025] The ultrasonic testing instrument body 1 has a wiring port 5 on its top, and a connecting wire 6 is provided inside the wiring port 5. One end of the connecting wire 6 is fixedly connected to the top of the connecting plate 7, and a stress testing instrument 8 is provided at the bottom of the connecting plate 7.

[0026] The fixing pin 902 is inserted and connected to the connecting plate 7. One end of the spring 910 is fixedly connected to one end of the storage rod 907. The spring 910 is sleeved on the surface of the telescopic slide rod 908.

[0027] The arc-shaped storage plate 911 is located above the storage rod 907, and one end of the arc-shaped protective plate 912 is fixedly connected to the end of the clamping rubber block 909 near the telescopic slide rod 908.

[0028] The positioning and fixing rod 914 is inserted and connected to the adjusting plate 906. The surface of the limiting plate 916 is fixedly connected to the surface of the limiting ring 904. By setting the arc-shaped storage plate 911 and the arc-shaped protective plate 912, which are located above the storage rod 907, the telescopic slide rod 908 and the spring 910, the arc-shaped protective plate 912 can protect the clamping structure composed of the storage rod 907, the telescopic slide rod 908 and the spring 910, so that external interference will not directly act on the clamping structure, thereby ensuring the stability of the clamping structure.

[0029] The working principle and usage process of this utility model are as follows: When it is necessary to clamp the stress detector 8 with a test object of different shapes to fix the two together, the clamping device 9 can be installed on the surface of the connecting plate 7 by means of the fixing nail 902 to realize the installation between the clamping device 9 and the connecting plate 7. The position of the adjusting plate 906 is adjusted according to the shape of the test object. The adjusting plate 906 can slide on the inner wall of the trapezoidal slide groove 905. When the adjusting plate 906 is adjusted to a position that is convenient for clamping the test object, the connecting slide rod 915 is pushed to slide inside the limiting plate 916. The positioning fixing rod 914, which is fixedly connected to the connecting slide rod 915, will be inserted into the limiting ring 904 and can move towards the adjusting plate 906 inside the limiting ring 904. The positioning fixing rod 914 will then be inserted into the limiting ring 904. The adjustment plate 906 is located inside the adjustment plate 906 and can be fixed. Other adjustment plates 906 are operated in a similar manner. Then, the object to be tested is placed in the clamping ring formed by multiple clamping rubber blocks 909 and clamped and fixed, so that it is in close contact with the stress detector 8. During the process of the object to be tested being clamped and fixed by the clamping ring, the telescopic slide rod 908 and the arc-shaped protective plate 912 will retract part of themselves into the storage rod 907 and the arc-shaped storage plate 911, respectively. The spring 910 will also be compressed and can provide clamping force for the object to be tested. At this time, the function of flexibly clamping objects of different shapes can be realized. When the stress detector 8 finishes testing, the object to be tested is removed from the clamping ring. The spring 910 will drive the clamping rubber block 909 to return to the position before the clamping state, so as to facilitate the clamping of the object to be tested next time.
