Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of weld detection, in particular to a tooling for aluminum alloy ultrasonic detection technology. Background Technique
[0002] When detecting aluminum alloy welds by A-type pulse echo ultrasonic testing, due to the reinforcement on the reverse side of the weld and specific structural forms, it is easy to make misjudgments when judging the primary wave and secondary wave, thus affecting the accurate positioning of defects.
[0003] Using phased array ultrasonic testing can prevent such misjudgments, but phased array ultrasonic testing equipment is quite expensive, and has relatively high requirements for the skills of personnel evaluating the spectrograms, which is not conducive to popularization and use. Content of the Utility Model
[0004] The purpose of the utility model is to provide a tooling for aluminum alloy ultrasonic detection technology to solve the problems put forward in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A tooling for aluminum alloy ultrasonic detection technology, including a scale plate, on which an adjustable scale plate is slidably connected, and a movable angle scale plate is slidably connected to the upper edge of the scale plate. The adjustable scale plate is of a U-shaped structure, and locking bolts are provided on both sides of the adjustable scale plate, and the locking bolts penetrate through the adjustable scale plate.
[0006] Preferably, on the surface of the scale plate, scales are provided at the upper edge and one side edge.
[0007] Preferably, the movable angle scale plate is composed of two parts, one part is an angle scale plate, and the other part is a clamping plate. The angle scale plate is located on the side of the scale plate with scales, and the clamping plate is clamped on the upper edge of the scale plate.
[0008] Preferably, the scale plate, the adjustable scale plate and the movable angle scale plate are all made of high-transparency plexiglass material.
[0009] Compared with the prior art, the beneficial effects of the utility model are: The overall structure is simple, the cost is low. Only by moving the adjustable scale plate and the movable angle scale, the propagation path of sound waves in aluminum alloy can be quickly simulated. Using high-transparency plexiglass material, it is flexible and convenient to use. Description of the Drawings

[0013] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0014] Please refer to FIGS. 1-2. An embodiment provided by the present utility model: An aluminum alloy ultrasonic testing technical tooling includes a scale plate 1, an adjustable scale plate 2 is slidably connected to the scale plate 1, a movable angle scale plate 3 is slidably connected to the upper edge of the scale plate 1. The adjustable scale plate 2 is of a U-shaped structure, and locking bolts 4 are provided on both sides of the adjustable scale plate 2. The locking bolts 4 penetrate through the adjustable scale plate 2, and the position of the adjustable scale plate 2 can be adjusted up and down according to the weld, and by using the distance between the adjustable scale plate 2 and the scale plate 1, the thickness of the component plate is simulated, which is more beneficial to fit the actual weld situation.
[0015] On the surface of the scale plate 1, scales are provided at the upper edge and one side edge, which is convenient for drawing the groove form diagram.
[0016] The movable angle scale plate 3 is composed of two parts, one part is an angle scale plate, and the other part is a clamping plate. The angle scale plate is located on the side with scales of the scale plate 1, and the clamping plate is clamped on the upper edge of the scale plate 1. By using the movable angle scale plate 3 and the measured values in the existing ultrasonic testing process, it is judged whether the echo is a primary echo or a secondary echo.
[0017] The scale plate 1, the adjustable scale plate 2 and the movable angle scale plate 3 are all made of highly transparent organic glass material, which is convenient for intuitively observing the values, and at the same time, marks can be made on the scale plate 1, the adjustable scale plate 2 and the movable angle scale plate 3 with a water-based pen.
[0018] Working principle: When in use, the thickness change of the aluminum alloy material is in the range of 10-40 mm, and the surface of the butt weld is generally not recommended to be polished, so there will be a reinforcement height in the actual weld;
[0019] During detection, by adjusting the adjustable scale plate 2, the thickness of the component plate is jointly simulated with the scale plate 1, and finally the screw 4 is locked. According to the actual measured width of the front and back of the weld and the groove dimensions measured before welding, a groove form diagram is drawn on the scale plate 1 with a wipeable oil-based pen, and a root reinforcement diagram is drawn on the scale plate 2;
[0020] The actual angle of the probe calibrated on the CSK-1A aluminum alloy standard test block is used to draw the path of the acoustic wave propagation on the angle scale plate 3;
[0021] Move the angle template 3 to simulate the actual movement of the probe on the aluminum alloy material. During the movement, observe and measure, and at the same time, combine the measured values during the ultrasonic testing process to compare and judge whether the echo is a primary echo or a secondary echo, and whether the echo is a structural wave or a defect wave.
