[0002] Coating porosity is a unit of measurement that describes the density of a coating and is one of the quantitative indicators that reflect the quality of a coating. It can directly affect the protective properties of a coating. As a wear-resistant coating, the pores in the coating can be used to store lubricants and accommodate abrasive particles, making the coating more wear-resistant.

[0003] There are many methods for measuring the porosity of coatings, such as the pressure pump method, image analysis software estimation method, etc. The image acquisition method uses a microscope to observe the coating surface, estimates the porosity by counting and measuring the number and size of pores, and uses image analysis software to accurately measure the characteristics of the pores. When collecting images of sample performance, in order to improve the measurement accuracy through multiple measurements, it is generally necessary for staff to move and adjust the position of the sample multiple times. During the movement, the image acquisition area may be repeated, which will lead to repeated data collection, waste time and resources, and may cause deviations in data analysis.

[0004] Therefore, it is necessary to design a device for measuring the surface porosity of wear-resistant coatings to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-4 A device for measuring the surface porosity of a wear-resistant coating comprises a porosity measuring device 1, an observation platform 2 is fixedly connected to the porosity measuring device 1, a fixed frame 3 is slidably connected to the observation platform 2, a placement plate 4 is fixedly connected to the inner side of the fixed frame 3, and the cross section of the placement plate 4 is a U-shaped structure. During measurement, the sample is directly placed on the placement plate 4, and the fixed frame 3 can play a role in fixing and limiting the placement plate 4 to prevent the sample from shaking during movement. A push plate 11 is fixed to the outer side of the fixed frame 3, a sliding rod 5 is fixedly connected to the observation platform 2, and a scale line is arranged on the sliding rod 5, and a plurality of baffles 6 are arranged on the sliding rod 5, and a blocking component for blocking the push plate 11 is arranged on the baffle 6, and a fixing component is also arranged inside the baffle 6.

[0024] Reference Figure 1 and Figure 3 The blocking component includes a slider 7, a sliding opening 10 is penetrated on the slider 7, the sliding rod 5 passes through the sliding opening 10, the side wall of the slider 7 is rotatably connected with a fixed shaft 8, the baffle 6 is fixedly sleeved on the fixed shaft 8, and a torsion spring 9 is provided between the fixed shaft 8 and the slider 7. By setting the blocking component, during the measurement process, when the push plate 11 contacts the baffle 6, an image acquisition operation can be performed. In this way, compared with the staff estimating the moving distance with the naked eye each time, the blocking component can not only improve the efficiency of sample movement, but also avoid duplication of the acquisition area, improve the accuracy of data measurement, especially in the measurement process of large-scale samples, it reduces the labor intensity of the staff.

[0025] Reference Figure 4The fixing assembly includes a fixing cavity 12 arranged inside the slider 7, a fixing block 13 is arranged inside the fixing cavity 12, a spring 16 is arranged between the top of the fixing block 13 and the inner top surface of the fixing cavity 12, two control blocks 14 are fixedly connected to the side wall of the fixing block 13, the bottom of the fixing block 13 extends to the inside of the sliding opening 10, two driving rods 15 are arranged inside the fixing cavity 12, the two driving rods 15 are respectively located on both sides of the fixing block 13, and an inclined surface is arranged at one end of the control block 14 facing the driving rod 15. Under the action of the inclined surface, the driving rod 15 moves toward the fixing cavity When moving in the inner part of the slider 7, the control block 14 can be squeezed, so that the control block 14 and the fixed block 13 move up, thereby achieving the purpose of separating the fixed block 13 from the slide bar 5. The end of the driving rod 15 away from the fixed block 13 extends to the outside of the slider 7, and the driving rod 15 is slidably connected with the slider 7. By setting a fixed component, the staff can quickly and conveniently adjust the position of the slider 7 according to the scale line. In this way, according to the size of the sample or the number of acquisitions, the staff can flexibly adjust the position of the baffle 6 to avoid duplication of the sample image acquisition area and ensure the accuracy of the porosity measurement.

[0026] Reference Figure 4 An anti-skid pad is fixed to one end of the fixing block 13 close to the slide bar 5, so that the friction between the fixing block 13 and the slide bar 5 can be increased, thereby ensuring the firmness of the fixation between the slider 7 and the slide bar 5.

[0027] Reference Figure 4 The cross section of the driving rod 15 is a T-shaped structure, which can prevent the driving rod 15 from escaping from the fixing cavity 12 and ensure the stability of the overall structure of the device.

[0028] Reference Figure 1 Two guide plates 17 are fixedly connected to the bottom of the fixed frame 3, and two guide grooves 18 are provided on the observation platform 2. The two guide plates 17 are respectively located in the two guide grooves 18, and the guide plates 17 are slidably connected to the guide grooves 18. On the one hand, the guide plates 17 and the guide grooves 18 can guide the movement of the fixed frame 3 to ensure the stability of the sample during movement. On the other hand, the guide plates 17 allow a certain space to exist between the fixed frame 3 and the observation platform 2. In this way, when the sample test is completed, the staff's hands can push the sample upward through this space to achieve rapid disassembly of the sample, which can improve the measurement efficiency and the convenience of the device operation.

[0029] The specific working principle of the utility model is as follows:

[0030] The sample workpiece to be measured is placed on the placement plate 4. The fixing frame 3 can play a role of fixing and limiting the placement plate 4 to prevent the sample from falling off the device during the movement. Then the staff pinches the driving rod 15 to make the driving rod 15 move toward the inside of the fixing cavity 12. Since the control block 14 is provided with an inclined surface on the side facing the driving rod 15, under the action of the inclined surface, the extrusion of the driving rod 15 can make the control block 14 move up, thereby driving the fixing block 13 to move up. At this time, the spring 16 is in a compressed state, and the fixing block 13 retracts into the fixing cavity 12, and the fixing block 13 is separated from the slide bar 5. At this time, the staff can slide the slider 7 along the slide bar 5 and drive the baffle 6 to move together. When the position adjustment of all the sliders 7 is completed, the spacing of each slider 7 is the same, and the driving rod 15 is released. Under the elastic force of the spring 16, the fixing block 13 moves down to reset and squeezes the slide bar 5, so that the slider 7 can be fixed on the slide bar 5.

[0031] Then the staff pushes the fixed frame 3. When the push plate 11 on the fixed frame 3 contacts the first baffle 6, the first image acquisition operation can be performed on the sample. Then the staff applies a little force to continue to push the fixed frame 3. At this time, the push plate 11 squeezes the baffle 6, causing the baffle 6 to rotate. When the push plate 11 is not in contact with the baffle 6, under the action of the torsion spring 9, the first baffle 6 is reset. When the fixed frame 3 moves the same distance and contacts the next baffle 6, the staff performs image acquisition again and repeats this step. In this way, different positions of the sample can be acquired, which can avoid the phenomenon of repeated image acquisition areas caused by manual visual movement of the sample distance, thereby ensuring the accuracy of the measurement results. The operation process is simple and convenient, eliminating the visual preparation link before each movement, and improving the efficiency of porosity measurement.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
