Description

Technical Field

[0001] This utility model belongs to the field of non-destructive testing technology, specifically an X-ray coating thickness measuring device. Background Technology

[0002] In industrial production, accurate measurement of the coating thickness on material surfaces is a crucial step in ensuring product quality and performance. X-ray coating thickness measurement, as a non-destructive testing method, directly impacts the efficiency and accuracy of the production process and the improvement of product yield.

[0003] Current X-ray coating thickness measurement devices have some shortcomings in practical applications. Firstly, traditional mechanical structures are relatively fixed and difficult to adapt to samples of different shapes and sizes, thus limiting the measurement range. For example, when dealing with complex curved surfaces or small workpieces, the insufficient flexibility of the positioning mechanism may prevent accurate adjustment of the relative position between the detector and the sample, affecting the accuracy of the measurement results. Secondly, existing sample fixing devices typically use a single clamping method, which can easily damage the sample surface due to excessive clamping force when dealing with soft or easily deformable samples, thus interfering with the coating thickness measurement data. Furthermore, some devices lack precise angle adjustment functions in their X-ray emission and reception modules, which may cause the X-ray incident angle to deviate from the optimal value, further reducing measurement accuracy. Therefore, those skilled in the art have proposed an improved X-ray coating thickness measurement device to address the problems mentioned in the background. Utility Model Content

[0043] The operation process of this utility model is as follows: First, the sample to be tested is placed on the sample stage 2. The position of the movable clamping plate in the clamping mechanism 10 is adjusted by rotating the handwheel to ensure that the sample is firmly clamped. The pressure sensor monitors the clamping force in real time and transmits the data to the controller. The controller adjusts the clamping force according to the preset value to avoid excessive clamping force damaging the sample. Then, the first servo motor drives the lead screw to rotate, causing the lifting block 7 to move up and down along the vertical guide rail 6, thereby adjusting the height of the detection component 3. The horizontal position of the detection component 3 is adjusted by the movement of the slider 9 in the groove of the crossbeam 8, and the scale marks and pointer are used for precise positioning. If the angle of the detection component 3 needs to be adjusted, the adjusting arm 13 in the angle adjusting component 4 is rotated, and the angle value is confirmed by the scale 19 and pointer 20 and fixed with locking bolts. For special angle requirements, the damper can reduce the sway of the adjusting arm 13 to ensure the stability of the angle adjustment. During the measurement process, the X-ray emitted by the X-ray emitter penetrates the sample and is received by the receiver. The signal is processed and transmitted to the controller and displayed on the display screen. The cooling module and calibration module ensure stable operation of the X-ray emitter and high accuracy of measurement data, respectively. Sound-absorbing material and exhaust fan 16 within the protective housing 5 effectively reduce external interference and internal heat buildup, ensuring a stable measurement environment.

[0044] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0045] In industrial production, a manufacturing company needs to measure the coating thickness of a batch of metal workpieces with complex curved surfaces. To ensure the accuracy and efficiency of the measurement results, the X-ray coating thickness measuring device described in this invention is used.

[0046] First, the sample to be tested is placed on the sample stage 2, ensuring that the positioning pin at its bottom is inserted into the positioning hole 17 for initial positioning. Then, the position of the movable clamping plate in the clamping mechanism 10 is adjusted by rotating the handwheel, causing the fixed clamping plate to engage with the movable clamping plate to clamp the sample. During this process, a pressure sensor embedded inside the movable clamping plate monitors the clamping force in real time and transmits the data to the controller. If the clamping force exceeds a preset value, the controller will send a signal to limit the movement of the clamping mechanism, thereby preventing damage to the sample surface due to excessive clamping force. This design is particularly suitable for samples with soft or easily deformable materials, effectively solving the problem of potential sample damage caused by traditional clamping methods.

[0047] Next, based on the shape and size of the sample, the first servo motor drives the lead screw to rotate, causing the lifting block 7 to move up and down along the vertical guide rail 6, thereby adjusting the height of the detection component 3. A pointer on one side of the lifting block 7 engages with a scale next to the vertical guide rail 6 to precisely control the lifting height. Simultaneously, the slider 9 moves horizontally within the groove of the crossbeam 8, and the pointer on the slider 9 engages with the scale markings on the crossbeam 8 to precisely position the horizontal position of the detection component 3. This adjustment process ensures that the detection component 3 can accurately align with the critical measurement area of ​​the sample.

[0048] For complex curved surface samples, the angle adjustment component 4 plays a crucial role. Through the cooperation of the rotating shaft 12 and the adjusting arm 13, the angle of the detection component 3 can be flexibly adjusted. The pointer on the adjusting arm 13, in conjunction with the scale 19, allows for precise confirmation of the rotation angle of the detection component 3. A locking bolt secures the adjusted angle, while a damper reduces the sway of the adjusting arm 13, improving the stability of the angle adjustment. This design solves the problem of the lack of precise angle adjustment function in existing X-ray emission and reception modules, ensuring that the X-ray incident angle is always maintained at the optimal value, thereby improving measurement accuracy.

[0049] During the measurement process, the X-rays emitted by the X-ray emitter penetrate the sample and are received by the receiver. The signal is processed and transmitted to the controller, and finally displayed on the screen. The heat sink and fan in the cooling module work together to reduce the operating temperature of the X-ray emitter, ensuring its stable operation over a long period of time. The filters and calibration plate in the calibration module further improve the accuracy of the measurement data, meeting the requirements of high-precision measurement.

[0050] To ensure the stability of the measurement environment, the design of the protective cover 5 plays a crucial role. The sound-absorbing material on the inside of the protective cover 5 absorbs external vibrations, reducing their impact on measurement accuracy; the ventilation opening 15 and exhaust fan 16 on the top effectively dissipate internal heat, preventing the equipment from overheating. In addition, the observation window 14 is made of transparent radiation-proof material, allowing operators to monitor the measurement process in real time.

[0051] Throughout the measurement process, the shock-absorbing pads and leveling feet at the bottom of base 1 work together to reduce the impact of external vibrations on the stability of the device and ensure that base 1 remains horizontal. The rotary disk 11 below sample stage 2 is driven by a second servo motor to rotate the bearing, causing the sample to rotate to different measurement angles. The scale ring 18 is used to indicate the rotation angle of the sample, facilitating recording and adjustment by the operator.

[0052] In summary, this invention, through its reasonable structural design and precise adjustment mechanism, achieves efficient and accurate measurement of samples with complex shapes, while avoiding the shortcomings of traditional equipment in terms of clamping force control, angle adjustment, and environmental stability, thus significantly improving the reliability and applicability of coating thickness measurement.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
