Technical Field

[0001] The utility model relates to the technical field of positioning devices, in particular to a metallographic microscope sample positioning device. Background Art

[0002] The metallographic microscope is mainly used to analyze the relationship between the organization of steel and its chemical composition by examining the organizational morphology. It can determine the microstructure of various types of steel after different processing and heat treatment. In this way, the quality of steel can be judged, such as the distribution and quantity of various types of steel inclusions - oxides, sulfides, etc. in the organization and the size of the metal grains. The submicroscopic structure of the steel can be observed using a metallographic microscope for the test samples after etching.

[0003] When observing a sample using an existing metallographic microscope, the user needs to constantly move the sample by hand and adjust the stage until the image is clear.

[0004] However, after manually adjusting the sample, if the position of the instrument is shifted due to vibration caused by touching the microscope, it will need to be readjusted, which is inconvenient to use. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a metallographic microscope sample positioning device, which overcomes the shortcomings of the existing technology and effectively solves the problem in the existing technology that if the vibration caused by touching the microscope causes the position of the instrument to be offset, it needs to be readjusted, which is inconvenient to use.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A metallographic microscope specimen positioning device comprises a shell, a plug-in frame is plugged into the top of the shell, an iron sheet is fixed to the top of the plug-in frame, a vessel is provided on the top of the iron sheet, and an iron block is adhered to the bottom of the vessel, a placement plate is provided in the shell, and connecting plates are fixed to the outer walls of both sides of the placement plate, both ends of the top of the placement plate are connected to clamping blocks, and a magnetic block placed on the top of the placement plate is provided between the two clamping blocks.

[0008] After placing the sample in the vessel, push the connecting plate downward to move the placement plate with the magnetic block downward away from the iron sheet and the iron block, releasing the magnetic adsorption of the iron block, making it easier to adjust the position of the vessel. After the adjustment is completed, push the connecting plate upward to move the magnetic block upward with the placement plate, so that the magnetic block is adsorbed on the bottom of the iron sheet and magnetically attracts the iron block, thereby fixing the position of the vessel and preventing the position of the vessel from shifting due to touching the microscope.

[0009] Preferably, positioning rods are fixed to the four corners of the bottom of the shell, and the shell is plugged into the observation platform of the metallographic microscope through the positioning rods.

[0010] The shell is fixed on the observation platform of the metallographic microscope through a positioning rod.

[0011] Preferably, both side outer walls of the shell are provided with operation openings, and the operation openings form a sliding fit with the connecting plates.

[0012] By moving the connecting plates on both sides of the operating port, the magnetic block can be moved closer to or away from the iron sheet.

[0013] Preferably, guide rods are fixed on both sides of the bottom of the shell, and the top of the connecting plate is provided with sockets adapted to the guide rods.

[0014] The connecting plate moves up and down along the guide rod, thereby improving the stability of the placement plate when moving up and down and preventing it from tilting.

[0015] Preferably, both ends of the top of the placement plate are provided with sliding grooves, and the sliding grooves form a sliding fit with the clamping blocks.

[0016] The two blocks move on top of the placement plate through a slide.

[0017] Preferably, both ends of the top of the magnetic block are provided with bayonet holes, and the bayonet holes and the clamping block form a snap fit.

[0018] After placing the magnetic block on the top of the placement plate, the magnetic block is fixed on the top of the placement plate by engaging the clamping block with the clamping port.

[0019] The beneficial effects of the utility model are:

[0020] By pushing the connecting plate downward, the magnetic block is moved downward away from the iron sheet, releasing the magnetic adsorption of the iron block, making it easier to adjust the position of the vessel. After the adjustment is completed, the connecting plate is pushed upward to make the magnetic block adsorbed on the bottom of the iron sheet, magnetically attracting the iron block, thereby fixing the position of the vessel, thereby preventing the position of the vessel from being shifted due to touching the microscope. This effectively solves the problem in the prior art that if the vibration caused by touching the microscope causes the position of the vessel to shift, it will need to be readjusted, which is inconvenient to use.
