Description

Technical Field

[0001] This utility model relates to the field of coating testing technology, specifically to a device for detecting the thickness of anti-oxidation coatings. Background Technology

[0002] In industrial production, metal parts often need to be coated with anti-oxidation coatings to isolate them from air and moisture, prevent electrochemical corrosion, and thus significantly extend their service life. The thickness of such coatings is a key indicator for measuring their protective performance. If the coating is too thin, it cannot form a complete and effective protective barrier and will not achieve the expected anti-oxidation effect. If the coating is too thick, it will not only increase production costs and waste materials, but may also cause problems such as coating cracking, peeling, and affecting the assembly dimensions of the workpiece. Therefore, rapid and accurate detection of the thickness of anti-oxidation coatings is an important link in ensuring product quality and economic benefits.

[0003] Currently, the industry mostly uses handheld thickness gauges, such as magnetic thickness gauges or eddy current thickness gauges, to measure coating thickness. While these instruments are portable, they have many limitations in practical applications:

[0004] 1. Low measurement efficiency and large human error: Handheld measurement relies heavily on the operator's skills and experience. During measurement, the probe needs to be manually subjected to stable pressure and kept vertical. Uneven pressure or tilting angle will directly lead to reading deviation. In addition, in order to measure multiple representative positions of the workpiece, the operator needs to continuously move the instrument manually and record data. The whole process is time-consuming and labor-intensive, and it is difficult to guarantee the accuracy and consistency of the measurement points.

[0005] 2. Poor adaptability to complex workpieces: When faced with workpieces with curved surfaces, irregular structures, or large dimensions, handheld thickness gauges are difficult to position stably, and the adhesion quality between the probe and the coating surface cannot be guaranteed, thus affecting the measurement accuracy. At the same time, for such workpieces, the lack of stable and adjustable support and positioning devices further increases the difficulty of standardized measurement. Utility Model Content

[0006] This utility model provides an anti-oxidation coating thickness detection device. Through the use of a support mechanism, it achieves adaptive and stable support and rapid positioning of irregularly shaped workpieces. A synchronous drive mechanism consisting of an adjusting motor, a bidirectional screw, and a synchronous belt can precisely control the synchronous movement of multiple pairs of sliding support blocks in opposite directions. This allows the device to quickly adapt to and stably clamp or support workpieces of different sizes and shapes, effectively overcoming the limitation of traditional detection tables that are only suitable for regular workpieces. The thickness detection mechanism provides constant pressure contact measurement, ensuring the accuracy and repeatability of the data. The pressing component, consisting of a top spring and a limiting rod, provides continuous and constant downward pressure to the detection lowering rod and the bonding head. This effectively avoids measurement errors caused by uneven manual operation or fluctuations in the equipment's own gravity. When the bonding head is pressed tightly against the coating surface with constant pressure, minute changes in its height are precisely sensed and converted into electrical signals through the displacement of the movable docking cone in the position sensing groove. These signals are then displayed intuitively on the data display module, fundamentally eliminating human interference and ensuring that each measurement is performed under the same mechanical conditions. This guarantees high accuracy and excellent repeatability of the measurement results.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a device for detecting the thickness of anti-oxidation coatings, comprising:

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a device for detecting the thickness of anti-oxidation coatings, comprising:

[0026] Detection seat 1;

[0027] A support mechanism is provided on the detection seat 1. The support mechanism includes a control component, a sliding support block 6 and a slide groove 7. Multiple slide grooves 7 are provided and are all opened on the detection seat 1. Multiple sliding support blocks 6 are provided and each sliding support block 6 is slidably connected to each slide groove 7. The control component is provided in the detection seat 1 and is connected to multiple sliding support blocks 6.

[0028] The thickness detection mechanism is mounted on the detection base 1. The thickness detection mechanism includes an adjustment component, a detection descending rod 9, a bonding head 10, a movable docking cone 8, and a position sensing groove 13. The adjustment component is mounted on the detection base 1, the detection descending rod 9 is mounted on the adjustment component, the bonding head 10 is fixedly connected to one end of the detection descending rod 9, the position sensing groove 13 is mounted on the adjustment component, and the movable docking cone 8 is fixedly connected to the other end of the detection descending rod 9 and is movably connected within the position sensing groove 13.

[0029] In this implementation scheme: every two sliding support blocks 6 correspond to each other. The sliding support blocks 6 move within the slide groove 7 to adjust the distance between the two sliding support blocks 6, thus completing the placement of different sizes and structures. The detection lowering rod 9 is pressed down by the adjusting component, so that the bonding head 10 is bonded to the workpiece being detected. During the movement of the workpiece being detected, the bonding head 10 slides relative to the slide bar at different positions, and the height is adjusted accordingly by the movable docking cone 8. It rises and falls within the position sensing groove 13 to complete the use.

[0030] Specifically, the control components include a positioning motor 2, a bidirectional screw 5, and a synchronization component. There are two bidirectional screws 5, which are rotatably connected to both sides of the detection seat 1, and each bidirectional screw 5 is threadedly connected to each of the two sliding support blocks 6. The positioning motor 2 is fixedly connected to one end of the detection seat 1, and the output end of the positioning motor 2 is fixedly connected to one end of one of the bidirectional screws 5.

[0031] In this embodiment, the model of the adjustment motor 2 can be selected from those available on the market as needed, which will not be elaborated here. The adjustment motor 2 controls the bidirectional screw 5 to rotate, thereby controlling the two corresponding sliding support blocks 6 to move and adjust relative to each other to ensure its use.

[0032] Specifically, the synchronization components include a timing belt 3 and timing pulleys 4. There are two timing pulleys 4, each of which is fixedly connected to one end of each bidirectional screw 5. The timing belt 3 is sleeved on the two timing pulleys 4, and the timing belt 3 and the two timing pulleys 4 mesh with each other.

[0033] In this embodiment, the two synchronous pulleys 4 are of the same size, and the two bidirectional screws 5 are rotated synchronously by the synchronous belt 3.

[0034] Specifically, the adjustment component includes an adjustment cylinder 16, an adjustment detection rod 14, and a pressing component. The adjustment cylinder 16 is fixedly connected to the detection seat 1, the adjustment detection rod 14 is slidably connected to the detection seat 1, and the adjustment detection rod 14 is fixedly connected to one end of the adjustment cylinder 16. The pressing component is located inside the adjustment detection rod 14 and is connected to the detection descending rod 9.

[0035] In this embodiment, the model of the adjusting cylinder 16 can be selected from those available on the market as needed, which will not be elaborated here. The adjusting cylinder 16 controls the adjusting detection rod 14 to move, thereby completing the position movement of the bonding head 10.

[0036] Specifically, the pressing component includes a top spring 12 and a limiting rod 11. The limiting rod 11 is fixedly connected inside the adjustment detection rod 14. The top spring 12 is sleeved on the limiting rod 11. One end of the top spring 12 is fixedly connected inside the adjustment detection rod 14, and the other end of the top spring 12 is fixedly connected to one end of the detection descending rod 9.

[0037] In this embodiment: the top spring 12 presses the detection descending rod 9 with its elastic force, so that the fitting head 10 fits the workpiece, and the limiting rod 11 restricts the downward pressing path of the detection descending rod 9, thus completing the use. Since the coating is in a smooth state, the elastic force of the top spring 12 will not act back and forth.

[0038] Specifically, a data display module 15 is fixedly connected to the top side of the detection base 1.

[0039] In this embodiment: the data display module 15 is an application of existing technology, which will not be described in detail here. The data display module 15 is electrically connected to the thickness detection mechanism to complete the data conversion, so that the height of the movable docking cone 8 sliding in the position sensing groove 13 is limited within the data display module 15 to complete the use.

[0040] In use, place the testing seat 1 stably on a horizontal workbench, connect the equipment power supply, and turn on the main switch. At this time, the data display module 15 should light up and perform a self-test. Confirm the drawing or specification requirements of the workpiece to be tested, and clarify the target thickness and allowable tolerance of the anti-oxidation coating. Place a workpiece of standard thickness in the blank area of ​​the testing seat 1 and proceed with the subsequent testing process. Press the bonding head 10 onto the standard workpiece and compare the reading of the data display module 15 with the known thickness of the standard gasket. If there is a deviation, calibration and compensation should be performed according to the equipment manual to ensure testing accuracy. According to the size and shape of the workpiece to be tested, start the adjustment motor 2. The adjustment motor 2 drives one of the bidirectional screws 5 to rotate. Through the transmission of the synchronous belt 3 and the synchronous pulley 4, the two bidirectional screws 5 rotate synchronously. The rotation of the bidirectional screws 5 will cause each pair of sliding support blocks 6 to move towards or away from each other in the slide groove 7. Adjust their positions, place the workpiece to be tested on or between the sliding support blocks 6, and start the adjustment cylinder. 16. The adjusting cylinder 16 pushes the adjusting detection rod 14 and its entire pressing component to move horizontally, precisely moving the bonding head 10 to the predetermined detection point above the workpiece. Under the constant pressure of the top spring 12, the bonding head 10 at the bottom of the detection descending rod 9 will press against the coating surface of the workpiece. When the bonding head 10 is in stable contact with the coating surface, the relative height position of the movable docking cone 8 at the other end of the detection descending rod 9 in the position sensing groove 13 is accurately sensed. This height position signal is converted into thickness data and displayed in real time on the data display module 15. The workpiece is slid to make the bonding head 10 measure the thickness along a line. During the measurement process, the thickness is converted synchronously. According to the detection specifications, this process is repeated in different representative areas of the workpiece to complete the measurement of all points. After the measurement of all points is completed, all readings are summarized from the data display module 15, the average thickness, minimum thickness, and maximum thickness are calculated, and compared with the target thickness and tolerance confirmed in the first step to determine whether the coating thickness is qualified.

[0041] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
