Description

Technical Field

[0001] The utility model relates to the technical field of coating detection, and particularly relates to a coating metallographic thickness detection device. Background Technique

[0002] The metallurgical microscope is a high-tech product developed by combining optical microscope technology, photoelectric conversion technology, and computer image processing technology. It is very convenient to observe metallographic images on a computer, so as to analyze and grade metallographic atlas, etc., and output and print pictures. As we all know, the composition of alloys, heat treatment processes, and hot and cold processing processes directly affect the changes in the internal structure of metal materials, thereby changing the mechanical properties of machine parts. Therefore, using a metallurgical microscope to observe, inspect, and analyze the internal structure of metals is an important means in industrial production.

[0003] In the prior art, metallurgical microscopes are also used to detect the thickness of coatings. However, most of the existing metallurgical microscopes have a fixed-stage structure. Therefore, when detecting the thickness of coatings, the samples to be detected need to be cut into thin slices along the cross-section, which requires high processing accuracy and is cumbersome. In addition, the thickness uniformity and surface physical properties of the cut thin slices cannot be detected, making the detection of a single sample limited and inconvenient to use. Therefore, a coating metallographic thickness detection device is needed. Content of the Utility Model

The limiting block is slidably connected in the installation groove, and the limiting block is elastically connected to the inner side of the installation groove through an elastic member.

[0009] Preferably, an inclined guiding slope is arranged between the upper end of the limiting block extending out of the installation groove and the side wall of the limiting block far away from the elastic member, and the guiding slope is inclined downward.

[0010] Preferably, a rounded edge is formed between the lower end of the guiding inclined surface and the bottom wall of the limiting block.

[0011] Preferably, the elastic member includes a return spring. One end of the return spring is fixed to the inner side wall of the installation groove, and the other end of the return spring is fixed to the side wall of one side of the limiting block.

[0012] Preferably, slots are formed on the side walls of opposite sides of the through hole of the stage. Connecting shafts are fixed to both ends of the slide plate, and the connecting shafts are rotatably connected in the slots;

[0013] The second limiting member includes anti-slip ribs. A plurality of anti-slip ribs are provided and are all fixed on the circumferential side wall of the connecting shaft. The anti-slip ribs are in interference fit with the inner side wall of the slot.

[0014] In summary, the technical effects and advantages of the present utility model are as follows:

[0016] 2. In the present utility model, through the arrangement of the anti-slip ribs, a large frictional force can be generated between the connecting shaft and the inner wall of the slot, so that the connecting shaft is not easy to rotate, thereby playing a role in limiting the slide plate and preventing the slide plate from rotating accidentally.

Specific implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment: Refer to Figures 1-3 A coating metallurgical thickness detection device shown in the figure, including a metallurgical microscope main body 1, and a stage 11 is arranged in the middle of the metallurgical microscope main body 1;

[0024] A through hole is opened in the middle of the stage 11, a carrier plate 2 is rotatably installed in the through hole of the stage 11, a carrier groove 21 for accommodating a sample and inserting a glass slide is opened at the upper end of the carrier plate 2, and a first limiting member for limiting the glass slide is installed on both sides of the carrier groove 21;

[0025] A second limiting member is arranged at the rotational connection between both sides of the carrier plate 2 and the through hole of the stage 11.

[0026] Based on the above structure, during use, the staff can place the sample to be detected in the sample carrier groove 21 of the carrier plate 2, cover the sample with a glass slide, and limit the glass slide through the limiting member 1, so that the sample is clamped and fixed between the bottom surface of the sample carrier groove 21 and the glass slide. At this time, the overall surface structure of the sample can be observed through the metallographic microscope body 1, so as to know the uniformity of the coating and other surface physical properties of the sample. Further, the staff only needs to rotate the carrier plate 2 to drive the sample to rotate, align the cross-section of the sample with the observation lens of the metallographic microscope body 1, and then the thickness of the coating and the metallographic structure of the sample (including the coating and the substrate) can be known. In this way, the coating metallographic thickness detection device can not only detect the thickness and metallographic structure of the coating, but also detect other physical properties of the coating or the sample, and the detection is more comprehensive. At the same time, there is no need to perform high-precision processing and slicing operations on the sample, saving the processing time and cost of some samples, thereby reducing the cost during detection, and the operation is simple and the use is convenient.

[0027] It should be noted that some positions of the carrier plate 2 (such as the bottom position of the sample carrier groove 21) can be made of glass material to form a transparent glass plate, which is used to cooperate with the clamping of the glass slide and can also facilitate the multi-surface detection of the sample, and the use effect is better.

[0028] Further, the limiting member 1 includes a limiting block 5. Installation grooves 22 are opened on both side walls of the sample carrier groove 21. The limiting block 5 is slidably connected in the installation groove 22, and the limiting block 5 is elastically connected to the inner side of the installation groove 22 through an elastic member;

[0029] An inclined guiding slope 51 is provided between the upper end of the limiting block 5 extending out of the installation groove 22 and the side wall of the limiting block 5 away from the elastic member. The guiding slope 51 is inclined downward, and a rounded corner 52 is formed between the lower end of the guiding slope 51 and the bottom wall of the limiting block 5;

[0030] The elastic member includes a return spring 6. One end of the return spring 6 is fixed to the inner side wall of the installation groove 22, and the other end of the return spring 6 is fixed to the side wall of one side of the limiting block 5.

[0031] Through the arrangement of the limiting block 5 and the return spring 6, after the sample is placed in the sample carrier groove 21, only by pressing the glass slide downward into the sample carrier groove 21, a certain pressure can be exerted on the guiding slope 51 by the glass slide. In this way, the limiting block 5 can be forced to contract into the installation groove 22 and compress the return spring 6. When the glass slide is successfully pressed in, the limiting block 5 pops out again under the elastic force of the return spring 6, so that the bottom surface of the limiting block 5 presses against and limits the glass slide, thus facilitating the placement of the sample and the glass slide, and can realize the rapid fixation of the sample, and the operation is simple and convenient.

[0032] Further, slots are provided on the side walls of the through holes on the opposite sides of the stage 11. Connecting shafts 3 are fixed at both ends of the slide plate 2, and the connecting shafts 3 are rotatably connected in the slots;

[0033] The second limiting member includes a resistance-increasing rib 4. The resistance-increasing rib 4 is a rib made of an elastic material with a large surface friction (such as rubber or silica gel). A plurality of resistance-increasing ribs 4 are provided and are all fixed on the peripheral side wall of the connecting shaft 3. The resistance-increasing rib 4 is in interference fit with the inner side wall of the slot.

[0034] Through the arrangement of the resistance-increasing rib 4, a large frictional force can be generated between the connecting shaft 3 and the inner wall of the slot, so that the connecting shaft 3 is not easily rotated, thereby playing a role in limiting the slide plate 2 and preventing the slide plate 2 from accidentally rotating. At the same time, the staff can rotate the slide plate 2 by applying a greater force, so as to facilitate the adjustment of the angle of the slide plate 2 and the limiting after the angle adjustment, which is also convenient to use.

[0035] The working principle of the present utility model: During daily use, the staff can place the sample to be detected in the sample slot 21 of the slide plate 2. After the sample is placed in the sample slot 21, the glass slide can be simply pressed downward into the sample slot 21, so that the glass slide can exert a certain pressure on the guiding inclined surface 51, thereby enabling the limiting block 5 to be forced to contract into the installation groove 22 and compress the return spring 6. When the glass slide is successfully pressed in, the limiting block 5 pops out again under the elastic force of the return spring 6, so that the bottom surface of the limiting block 5 abuts and limits the glass slide, thus facilitating the placement of the sample and the glass slide, and enabling the sample to be quickly fixed, so that the sample is clamped and fixed between the bottom surface of the sample slot 21 and the glass slide. At this time, the overall surface structure of the sample can be observed through the metallurgical microscope body 1, so as to know the uniformity of the coating and other surface physical properties of the sample. Further, the staff only needs to rotate the slide plate 2 to drive the sample to rotate, and align the cross-section of the sample with the observation lens of the metallurgical microscope body 1, then the thickness of the coating and the metallographic structure of the sample can be known. In this way, the coating metallographic thickness detection device can not only detect the thickness and metallographic structure of the coating, but also detect other physical properties of the coating or the sample, the detection is more comprehensive. At the same time, there is no need to perform high-precision processing and slicing operations on the sample, saving the processing time and cost of some samples, thereby reducing the cost during detection, and the operation is simple and the use is convenient.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
