Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ultrasonic nondestructive flaw detection, in particular to an ultrasonic probe fixing device. Background Art
[0002] Manual ultrasonic testing is widely used in non-destructive testing of steel structures in the field of engineering inspection. When we detect the weld of the workpiece, when a defect wave appears on the flaw detector, we need to locate and quantitatively measure the defect. At this time, it is necessary to use a ruler and a stone pencil to mark the defect position on the steel plate, and to add and subtract gain on the instrument, and then record the measurement data on paper. This series of operations requires the inspector to press the probe with one hand and perform the above-mentioned recording operation with the other hand. Since the ultrasonic probe is very sensitive, in actual flaw detection, as long as the probe moves slightly, it will cause errors in quantitative positioning measurement. In order to obtain more accurate data, it is often necessary to perform repeated measurements many times, which is time-consuming and laborious. This device is developed to solve this problem, so that the probe can be fixed on the workpiece steel plate anytime and anywhere during the flaw detection process. Utility Model Content

Compared with the prior art, the device mainly plays a role in reducing defect measurement errors in the actual flaw detection process, while saving time and effort and facilitating the operation and recording of detection personnel, thereby improving work efficiency.

[0005] According to the ultrasonic probe fixing device, the number of the iron sheets is two and they are symmetrically distributed on the top of the plastic sleeve shell.
[0006] According to the ultrasonic probe fixing device, the number of the permanent magnets and the number of the magnet push keys are both two, and they are symmetrically distributed on the left and right sides of the probe body.

[0019] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.
[0020] Reference Figure 1-4The utility model embodiment is an ultrasonic probe fixing device, which includes: a probe body 1, a probe line 2 is fixedly connected to the top of the probe body 1, a plastic shell 5 is arranged outside the probe body 1, the plastic shell 5 is in a "door" shape, the top of the probe body 1 is fixedly connected to the inner top surface of the plastic shell 5, a card slot is arranged on the top of the plastic shell 5, an iron sheet 6 is clamped inside the card slot, the number of the iron sheets 6 is two, and they are symmetrically distributed on the top of the plastic shell 5, a permanent magnet 3 is slidingly arranged inside the plastic shell 5, and a magnet push button 4 is fixedly connected to the end of the permanent magnet 3 away from the plastic shell 5, and the plastic shell The left and right side walls of the shell 5 are both provided with oblong holes, and the magnet push button 4 passes through the oblong holes. There are two permanent magnets 3 and two magnet push buttons 4, and they are symmetrically distributed on the left and right sides of the probe body 1. The permanent magnet 3 is located below the iron sheet 6. When the magnet push buttons 4 on both sides are pushed, the permanent magnet 3 can be adsorbed on the iron sheet 6, thereby separating the device. The magnet push buttons 4 on both sides can also be pushed to make the permanent magnet 3 adsorbed on the steel plate 8, thereby fixing the device. A steel plate 8 is provided at the bottom of the probe body 1, and a weld 7 is provided on the steel plate 8. The probe body 1 is located above the weld 7, which is convenient for the handheld device to move parallel to the weld 7 for flaw detection.
[0021] Working principle: During flaw detection, the handheld device moves parallel to the weld 7. When a defect is found inside the weld 7, the magnet push button 4 is pushed down along the oblong hole to adsorb the steel plate 8, thereby fixing the probe body 1, so that both hands can be freed to carry out the next step of quantitative positioning measurement and recording of defects. When it is not necessary to fix the probe body 1, the inspector can use the thumb and index finger to push the two magnet push buttons 4 upward along the oblong hole to adsorb the iron sheet 6 embedded in the top surface of the plastic sleeve shell 5, so that the device can be picked up.
