[0002] Eddy current testing is a non-destructive testing technology mainly used to detect defects in metal materials and evaluate the properties of materials. This technology is based on the principle of electromagnetic induction and uses the generation and change of eddy currents to detect metals. It has many advantages such as non-destructive testing, high sensitivity, and a wide range of applications. It is widely used in aerospace, automotive industry and other fields.

[0003] During the inspection of copper or copper alloy rods, the operator is required to hold the part to be inspected in one hand and the inspection probe in the other. Although this is more convenient, the operator's hand may shake during the operation, resulting in inaccurate inspection results and the need for repeated inspections. In addition, when inspecting rod-shaped objects, since the part to be inspected is in a rod shape and has no reference, it is easy to miss the inspection position during inspection, resulting in a decrease in inspection accuracy. This requires a device to solve the above problems. Utility Model Content

[0021] The clamping mechanism includes a fixed portion 2, a movable portion 3 and a clamping sleeve 4. The fixed portion 2 is fixedly connected to one side of the base 1. The clamping sleeve 4 is detachably arranged inside the fixed portion 2. A driving wheel 5 is provided on one side of the base 1. The outer circumference of the driving wheel 5 engages with the outer circumference of the clamping sleeve 4. An adjustment groove 6 is provided on the upper surface of the base 1. The movable portion 3 is slidably arranged inside the adjustment groove 6.

[0022] The supporting mechanism includes a supporting seat 7, a connecting rod 8 and a mounting plate 9. The supporting seat 7 is slidably arranged on the upper surface of the base 1. The supporting seat 7 is connected to the connecting rod 8 through a rotating shaft. One end of the connecting rod 8 is connected to the mounting plate 9 through a rotating shaft. The mounting plate 9 is used to fix the probe.

[0023] The clamping sleeve 4 is designed in two halves. The inner diameter of the clamping sleeve 4 can be adjusted by replacing the clamping sleeve 4 to adapt to parts of different sizes to be measured. After the clamping sleeve 4 is fixed together with the fixing part 2 and the part to be measured is fixed, the driving wheel 5 is engaged with the clamping sleeve 4. When the driving wheel 5 rotates, the clamping sleeve 4 can be driven to rotate together, and the clamping sleeve 4 can further drive the part to be measured to rotate. A driving mechanism is provided in the base 1 for driving the driving wheel 5 to rotate. The movable part 3 is provided in the adjusting groove 6 and can slide in the adjusting groove 6. When fixing shorter parts, it can slide toward one end of the fixing part 2 to improve applicability. The probe can be fixed to the mounting plate 9 by bolts. The support seat 7, the connecting rod 8 and the mounting plate 9 are all connected by a rotating shaft, and a fixing mechanism is provided to fix the relative position, thereby adjusting the orientation position of the mounting plate 9 to facilitate adjusting the probe to the appropriate position.

[0024] In this embodiment, as a preferred solution, an auxiliary sleeve 10 is replaceably provided inside the movable part 3, and a protrusion 11 is provided inside the auxiliary sleeve 10 and the clamping sleeve 4 for fixing the measured part. A friction pad 12 is provided on the upper surface of the base 1, and a fixing bolt 13 is provided on one side of the movable part 3. The bottom of the fixing bolt 13 is pressed against the surface of the friction pad 12 to fix the position of the movable part 3.

[0025] The protrusion 11 can press against the parts fixed inside, improve the stability during fixation, and reduce the shaking of the parts during the detection process. When the fixing bolt 13 is rotated, the fixing bolt 13 can press against the friction pad 12, thereby fixing the position of the movable part 3 and preventing the movable part 3 from moving.

The output end of the drive motor 16 is connected to one end of the threaded rod 15 through a keyway, and the outer cylindrical surface of the threaded rod 15 is connected to the internal thread of the support seat 7.

[0027] When the driving motor 16 rotates, it drives the threaded rod 15 to rotate, and then the threaded rod 15 drives the support base 7 connected to the outer cylindrical surface to move. During the movement of the support base 7, the probe installed on the mounting base can detect the parts to be tested, thereby improving the detection efficiency. A scale is provided on the side of the base 1, so that the moving distance can be more clearly checked when the support base 7 moves.

[0028] In this embodiment, as a preferred solution, a limiting groove 17 is provided inside the fixing portion 2, and a limiting block 18 is provided on the outer surface of the clamping sleeve 4. The limiting block 18 is engaged with the limiting groove 17 to limit the movement of the clamping sleeve 4.

[0029] The limiting groove 17 limits the movement of the clamping sleeve 4 so that the clamping sleeve 4 can only rotate to prevent the clamping sleeve 4 from slipping out of the fixed part 2 during the detection process, thereby improving the stability during detection. The auxiliary sleeve 10 and the movable part 3 are also provided with a limiting block 18 and a limiting groove 17 to limit the movement of the auxiliary sleeve 10.

[0033] 3. After fixing the part to be measured, move the support base 7 to one end of the part to be measured, fix the probe on the mounting plate 9, and adjust the angles of the connecting rod 8 and the mounting plate 9 so that the probe is close to the part to be measured;

[0034] 4. Turn on the driving mechanism to make the driving wheel 5 drive the clamping sleeve 4 to rotate, and the clamping sleeve 4 drives the measured part to rotate. When the measured part rotates, operate the driving motor 16 to adjust the position of the support base 7. Use the probe to detect the measured workpiece. According to the scale set on the side, check the moving distance of the support base 7 so as to adjust the position of the support base 7 in time.

[0035] 5. After the test is completed, remove the tested parts from the device.
