Description

Technical Field

[0001] This utility model relates to the field of metallographic optical inspection instruments, and more specifically, to a metallographic optical inspection instrument. Background Technology

[0002] Metallographic optical inspection instrument is a precision optical instrument specifically used to observe and analyze the microstructure of metallic materials. It reveals the metallographic structure of materials through optical magnification and imaging technology, combined with sample preparation and special illumination methods. It is an important tool in the fields of materials science, metallurgy, and mechanical manufacturing.

[0003] For the observation of some special samples, there are temperature requirements. However, the existing equipment cannot maintain a constant temperature during operation. Temperature changes will affect the stability of high-magnification imaging. In addition, some observation operations may be caused by the vibration and displacement of the sample due to external environmental factors, resulting in blurred imaging.

[0004] Based on this, this utility model discloses a metallographic optical inspection instrument. Utility Model Content

[0005] To address the issues raised in the background art regarding the observation of certain special samples, where temperature requirements exist and existing devices cannot maintain a constant temperature during operation, temperature variations affect the stability of high-magnification imaging, and some observation operations suffer from sample vibration and displacement due to external environmental factors, leading to blurred images, this invention provides a metallographic optical inspection instrument. The instrument includes a support stage with a temperature-controlled component. This component includes an enclosing frame, a cover plate fixed to the top of the enclosing frame, and a structural groove on the top of the cover plate. An enclosing cavity is formed between the enclosing frames. First mounting grooves are symmetrically formed on the inner walls of both sides of the enclosing cavity, and a first heating plate is installed inside each of the first mounting grooves. Second mounting grooves are symmetrically formed on the inner walls of both ends of the enclosing cavity, and a second heating plate is installed inside each of the second mounting grooves. An elastic pressure strip is mounted around the bottom end face of the enclosing frame. Fixing blocks are symmetrically mounted on the outer surfaces of both ends of the enclosing frame, and rubber suction cups are mounted on the fixing blocks. An auxiliary fixing component is also installed on the enclosing frame.

[0006] As a further improvement to this technical solution, a rotating groove is provided through the top of the fixed block, a fixed short shaft is installed inside the rotating groove, and a toggle rod is provided inside the rotating groove. The toggle rod is rotatably sleeved outside the cross section of the fixed short shaft. The bottom of the toggle rod is connected to a rubber suction cup, and a connecting rod is fixed to the top of the toggle rod at the same end.

[0007] As a further improvement to this technical solution, when the lever is in the vertical state, the horizontal plane where the bottom end face of the rubber suction cup is located is lower than the horizontal plane where the bottom end face of the elastic pressure strip is located.

[0008] As a further improvement to this technical solution, the auxiliary fixing component includes an adjustment groove. The adjustment grooves are symmetrically opened at the lower position of the inner wall surface on both sides of the enclosing cavity. A screw is rotatably installed in the space opened on one side of the adjustment groove. A movable frame is set in the space opened at the same end of the adjustment groove. One end of the movable frame is sleeved on the outside of the cross section of the screw through a screw hole. A clamping plate is fixedly connected to each movable frame.

[0009] As a further improvement to this technical solution, the end of each screw away from the center point of the enclosure frame extends outward through the plate of the enclosure frame and is equipped with an adjustment knob.

[0010] As a further improvement to this technical solution, the rotation trajectory of the adjustment knob does not contact the installation position of the fixing block, and the horizontal plane where the bottom end face of the clamping plate is located is higher than the horizontal plane where the bottom end face of the enclosure frame is located.

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Therefore, this utility model provides a metallographic optical inspection instrument, see [link to relevant documentation]. Figures 1-3 As shown, it includes a support platform 1, on which a temperature control component is installed. The temperature control component includes an enclosing frame 2, and a cover plate 3 is fixed to the top of the enclosing frame 2. A structural groove is opened on the top of the cover plate 3. An enclosing cavity 4 is enclosed between the enclosing frames 2. First mounting grooves 6 are symmetrically opened on the inner walls of both sides of the enclosing cavity 4. A first heating plate 7 is installed inside the first mounting groove 6. Second mounting grooves 8 are symmetrically opened on the inner walls of both ends of the enclosing cavity 4. A second heating plate 9 is installed inside the second mounting groove 8. An elastic pressure strip 5 is installed around the bottom end face of the enclosing frame 2. Fixing blocks 10 are symmetrically installed on the outer sides of both ends of the enclosing frame 2. Rubber suction cups 14 are provided on the fixing blocks 10. An auxiliary fixing component is installed on the enclosing frame 2. A control panel is installed on the outer side of the enclosing frame 2, which can control the operating temperature of the first heating plate 7 and the second heating plate 9 to achieve temperature setting of the internal space of the enclosing cavity 4. The structural groove on the top of the cover plate 3 can ensure the smooth operation of the observation lens.

[0022] A rotating groove 11 is provided through the top of the fixed block 10. A fixed short shaft 12 is installed inside the rotating groove 11, and a toggle rod 13 is provided inside the rotating groove 11. The toggle rod 13 is rotatably sleeved outside the cross-section of the fixed short shaft 12. The bottom of the toggle rod 13 is connected to the rubber suction cup 14, and a connecting rod 15 is fixed to the top of the toggle rod 13 at the same end. After the inspection is completed, by applying a force to the connecting rod 15 in the direction of the enclosing frame 2, the toggle rod 13 rotates around the fixed short shaft 12. The rubber suction cup 14 at the bottom of the toggle rod 13 is lifted up, so that the suction force of the rubber suction cup 14 on the top end face of the support platform 1 disappears, and the limiting effect of the enclosing frame 2 on the support platform 1 is released.

[0023] When the lever 13 is in the vertical position, the horizontal plane of the bottom end face of the rubber suction cup 14 is lower than the horizontal plane of the bottom end face of the elastic pressure strip 5.

[0024] During operation, thanks to the structural design of the constant temperature component, before testing the metal block, the metal block to be tested is placed on top of the support platform 1, and then the enclosure frame 2 is placed on top of the support platform 1, so that the metal block is located inside the enclosure cavity 4. By applying a downward force to the connecting rod 15, the rubber suction cup 14 is adsorbed on top of the support platform 1, and the bottom end face of the elastic pressure strip 5 is pressed tightly against the top of the support platform 1. Subsequently, the control panel is adjusted to regulate and preheat the working environment inside the enclosure cavity 4, so that the temperature inside the enclosure cavity 4 remains constant, meeting the requirements of high-temperature or low-temperature metallographic analysis and avoiding the impact of temperature changes on high-magnification imaging.

[0025] Further, see Figures 1-2 , Figure 4 As shown, the auxiliary fixing assembly includes an adjustment groove 16. The adjustment grooves 16 are symmetrically provided on the lower part of the inner wall surface on both sides of the enclosing cavity 4. A screw 17 is rotatably installed in the space opened on one side of the adjustment groove 16. A movable frame 18 is provided in the space opened at the same end of the adjustment groove 16. One end of the movable frame 18 is sleeved on the outside of the cross section of the screw 17 through a screw hole. A clamping plate 19 is fixedly connected to each movable frame 18.

[0026] The end of each screw 17 furthest from the center point of the enclosure frame 2 extends through the plate of the enclosure frame 2 and is equipped with an adjustment knob 20. Each adjustment knob 20 ensures that the movable frame 18 and the clamping plate 19 on the same side can move freely, which can accommodate the observation of irregular metal blocks.

[0027] The rotation trajectory of the adjusting knob 20 does not contact the installation position of the fixing block 10, and the horizontal plane where the bottom end face of the clamping plate 19 is located is higher than the horizontal plane where the bottom end face of the enclosure frame 2 is located.

[0028] During operation, through the structural design of the auxiliary fixing components, after the working position of the enclosure frame 2 is fixed before observation, force can be applied to the adjustment knobs 20 at both ends of the enclosure frame 2 respectively. The screw 17 rotates, and the moving frame 18 drives the clamping plate 19 to move along the adjustment groove 16. The clamping plates 19 at both ends clamp the two ends of the metal block, which can fix the metal block in a suitable position and avoid the phenomenon of metal block vibration and displacement caused by environmental vibration, thus ensuring image clarity.

[0029] In summary, this effectively solves the problems of temperature requirements for observing certain special samples, the inability of existing devices to maintain a constant temperature during operation, the impact of temperature changes on the stability of high-magnification imaging, and the blurring of images caused by sample vibration due to external environmental factors during some observation operations.
