Description

TECHNICAL FIELD

[0001] The utility model relates to ultrasonic testing technical field, concretely is a kind of positioning device for ultrasonic testing. BACKGROUND

[0002] The basic principle of ultrasonic nondestructive testing is that the discontinuity of material caused by the existence of uneven defects in uniform material produces interfaces of different sizes in the interior of the material, resulting in inconsistent acoustic impedance. Ultrasonic waves will reflect on the interface of media with different acoustic impedance (or "defects"), and ultrasonic testing is used to determine the location and size of defects in the workpiece by using the reflection of such interfaces. When finding defect characteristics, the inspector needs to measure the distance from the probe front surface of a certain point of welding using a ruler. Since the probe needs to be moved frequently during detection, the inspector's measurement efficiency is low and the task is heavy.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-4 As shown, a positioning device for ultrasonic testing includes a probe body 1, a base plate 2 disposed on the upper surface of the probe body 1, fastening mechanisms 3 disposed on both outer surfaces of the base plate 2, a receiving groove 4 formed on the front surface of the base plate 2, a positioning plate 5 disposed inside the receiving groove 4 and extending to the outside, a fixing mechanism 6 disposed on the upper surface of the base plate 2, a laser rangefinder 7 disposed inside the fixing mechanism 6, and the fastening mechanism 3 includes threaded rods 31 threadedly connected to both outer surfaces of the base plate 2, a clamping plate 32 rotatably connected to the outside of the threaded rods 31, and both outer surfaces of one side of the clamping plate 32 being fixedly connected to... A limiting rod 33 is connected and slidably connected to the inside of the substrate 2. An anti-slip pad 34 is provided on the lower side of one outer surface of the clamping plate 32. The anti-slip pad 34 is an embedded design. The anti-slip pad 34 can improve the clamping effect and prevent slippage. The fixing mechanism 6 includes a lower buckle plate 61 provided on the upper surface of the substrate 2. A hinge 62 is provided on one upper surface of the lower buckle plate 61. An upper buckle plate 63 is fixedly connected to the outer circular surface of the pivot of the hinge 62. A fixing buckle 64 is fixedly connected to one lower surface of the upper buckle plate 63. A slot for the fixing buckle 64 to engage is opened on the upper surface of the lower buckle plate 61.

[0022] By adopting the above technical solution, when this positioning device needs to be installed, the base plate 2 can be fastened to the probe body 1 using the fastening mechanism 3. During fastening, a screwdriver is required. By rotating the threaded rods 31 on both sides with the screwdriver, the clamping plate 32 can be driven to clamp and fasten the probe body 1. The limiting rod 33 can slide inside the base plate 2 for auxiliary limiting. The upper buckle 63 can be rotated and opened by moving the fixing buckle 64. The laser rangefinder 7 can be placed between the upper buckle 63 and the lower buckle 61. The positioning plate 5 inside the storage slot 4 can be pulled out and placed on the target point. The side of the laser rangefinder 7 that is irradiated by the laser point on the positioning plate 5 should be on the same vertical plane as the target point. This method can quickly measure the distance from a certain point of the weld to the front surface of the probe body 1. The fixing mechanism 6 makes it convenient to quickly disassemble and charge the laser rangefinder 7 after installation.

[0023] like Figures 2-3As shown, the upper surface of the substrate 2 is fixedly connected with a limiting strip 8 on both sides, the outer surface of the lower buckle plate 61 is provided with a fixed screw hole 9 on both sides, and the outer surface of the limiting strip 8 extends to the inner surface and is threadedly connected with a fixed screw 10.

[0024] Further, the front surface of the substrate 2 is provided with a magnetic block 11 above the receiving groove 4, and the positioning plate 5 is made of iron and can be adsorbed on the magnetic block 11. The adsorption of the magnetic block 11 can prevent the positioning plate 5 from accidentally slipping out of the receiving groove 4.

[0025] Further, the inner top of the upper buckle plate 63 is fixedly connected with an anti-skid rubber pad 12, and the inner bottom of the lower buckle plate 61 is provided with an anti-skid sticker 13. The anti-skid rubber pad 12 can further improve the fastening effect of the laser range finder 7 and prevent the laser range finder 7 from slipping out of the fixing mechanism 6.

[0026] Working principle: when using the positioning device for ultrasonic detection, first, when the positioning device needs to be installed, the substrate 2 can be fastened to the probe body 1 by using the fastening mechanism 3. When fastening, a screwdriver is needed to fasten. By rotating the threaded rods 31 on both sides with the screwdriver, the clamping plates 32 can clamp and fasten the probe body 1. The limiting rods 33 can slide in the substrate 2 to assist in limiting. By rotating the opening of the upper buckle plate 63 by pulling out the positioning plate 5 in the receiving groove 4 and placing it on the target point, the laser point of the laser range finder 7 is irradiated on one side of the positioning plate 5, which needs to be on the same vertical plane with the target point. This method can quickly measure the distance from the probe body 1 to the front surface of the weld at a certain point. The limiting strip 8 can limit the lower buckle plate 61 to ensure that it is vertically forward. The fixed screw 10 can be connected in the fixed screw hole 9. This design makes the fixing mechanism 6 and the substrate 2 a detachable split design, which is convenient for disassembly and transportation. This is the working principle of the positioning device for ultrasonic detection.
