Description

Technical Field

[0001] The utility model relates to the field of ultrasonic nondestructive testing, and relates to a probe clamping device for manually fine-tuning an angle. Background Art

[0002] With the continuous innovation of production technology, the mechanical processing and parts industry is striding towards high-quality development, and people are gradually paying attention to production quality, especially the quality of parts in high-end fields such as aerospace parts and targets. People have come up with many ways to detect the quality of parts, among which ultrasonic non-destructive testing technology is a commonly used detection method. This technology can help ensure the safety and reliability of parts by using ultrasound to detect defects and problems in materials.

[0003] The ultrasonic wave propagates in the material to detect defects in the material. When the ultrasonic wave encounters defects in the material, it will be reflected, scattered, or transmitted, so that the problem in the material can be determined by detecting these reflected or scattered signals. Water immersion ultrasonic testing usually requires the material to be immersed in water to ensure that the ultrasonic wave can effectively propagate and detect problems in the material.

[0004] Water immersion ultrasonic testing has a wide range of applications in many fields. In the industrial field, it is often used to detect cracks, pores and other defects in metal and non-metal materials to ensure the safe operation of industrial equipment. Compared with other detection technologies, water immersion ultrasonic testing has many advantages. First, it is a non-destructive detection technology that can be used for detection without destroying the material or structure. Second, water immersion ultrasonic testing can provide high-resolution detection results and can accurately determine the problem in the material.

[0005] The selection of the probe position is very important for the accuracy of the detection. Only by accurately aligning the probe with the object to be detected can the reliability of the data be ensured. The swing angle of the angular displacement stage on the market is not large enough and the angle can only be adjusted in one plane, which cannot guarantee that the probe will be moved to the appropriate position. Utility Model Content

[0006] The technical problems to be solved by the utility model are:

[0007] How to increase the adjustable angle range of the angular displacement stage, increase the directions of the angle adjustment, and at the same time ensure the function of fine-tuning the angle, so that it can accurately adjust the angle and ensure stability during the adjustment process.

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0012] The central block (8) has a countersunk threaded hole on its side, into which two screws can be screwed to push against the worm gear shaft, thereby fixing the worm gear shaft and achieving locking.

[0013] The worm gear cover (11) rotates along with the worm gear shaft and is provided with a small notch pointing to the scale plate (18) to indicate the angle.

[0014] The worm gear frame (9) is composed of two lobes, which is convenient for installing the worm shaft (14).

[0015] The position of the center block is adjusted by rotating the adjustment knob (2), which can drive the worm shaft (14) and the worm (12) to rotate; the worm (14) in turn drives the worm wheel (6) and the worm wheel shaft to rotate, and the worm wheel shaft drives the center block (8) to rotate through a key connection, thereby realizing the first direction adjustment of the probe (3).

[0016] The position of the lower connecting block is adjusted, the worm gear is fixed, and the adjusting knob (2) is rotated to drive the worm shaft (14) and the worm (12) to rotate around the worm gear, and the lower connecting block (10) is rotated to achieve the second direction adjustment of the probe (3).

[0017] The probe tooling (4) is provided with a hole for installing the probe (3) and a threaded hole on the side. The probe (3) is placed in the middle of the hole and fixed with a top screw.

[0018] The two adjusting knobs (2) are fixed to the two worm shafts (14) with screws. A keyway is provided on the worm shaft, and the key is installed before the worm shaft is inserted into the center block (8). The worm frame (9) is divided into two parts, which are connected with screws, and a small shaft sleeve (15) and a large shaft sleeve (16) are installed in the hole of the worm frame.

[0019] The worm (12) is provided with a threaded hole and is fixed on the worm shaft (14). The worm wheel (6) is provided with a threaded hole and is fixed on the worm wheel shaft (14).

[0020] Since the worm thread has a small adjustment range and the turbine radius is relatively large, the turbine only rotates a small range when the worm is adjusted a large circle, and the position of the probe can be adjusted slightly, achieving precise adjustment.
