[0016] The technical solution of this utility model will now be described in detail with reference to the accompanying drawings.

[0017] like Figure 1 As shown, a high-precision height measuring microscope device according to an embodiment of the present invention includes a microscope assembly, a positioning device 1, a zeroing device 2, and a dial indicator 3; one end of the positioning device 1 is connected to the microscope assembly, and the other end is connected to the dial indicator 3; the zeroing device 2 is mounted on the microscope assembly and is positioned above the positioning device 1, and the dial indicator 3 is positioned on the side of the microscope assembly.

[0018] In the high-precision height-measuring microscope device described above, the microscope assembly and dial indicator 3 are combined. The microscope magnifies the detection area, the focusing device 7 accurately positions the measurement surfaces at different heights, and finally, the dial indicator 3 measures the height difference and records the reading. By coordinating the microscope assembly and dial indicator 3, the height difference of the microscopic measurement area can be measured more accurately, and the height difference is accurately reflected in the dial indicator 3 reading. This device has a simple overall structure, is more portable, and can be applied to various working conditions, thus broadening its application scenarios.

[0019] When measuring the microscopic measurement area, firstly, the focusing device 7 of the microscope assembly is used to focus at the first point in the measurement area. Once the vertical focus is clear, the zeroing function of the dial indicator is used to record the zero position. Then, the focusing device 7 is used again to focus at the second point in the measurement area. Once the second point is clear, the value is read from the digital display screen 33 on the dial indicator 3. The value on the digital display screen 33 is the accurate value of the height difference between the two points. During reading, the digital display screen 33 is rotated by the rotating bracket 34 to rotate it to the optimal angle, making the reading faster and more convenient, and improving the efficiency of the measurement.

[0020] When the focusing device 7 is focusing, it will cause the lens barrel 5 to move up and down. The zeroing device 2 is set on the lens barrel 5, so the zeroing device 2 moves up and down with the lens barrel 5. The contact point at the top of the measuring rod 31 contacts the lower surface of the zeroing device 2, and the measuring rod 31 can move up and down through the elastic component. Therefore, the measuring rod 31 moves up and down with the zeroing device 2. When the focusing device 7 focuses on the first point, as the focusing device 7 rotates, the lens barrel 5, the zeroing device 2, and the measuring rod 31 will all move up and down synchronously. When the focusing of the first point is completed, the zeroing function of the dial indicator 3 will record the zero position. At this time, the lens barrel 5, the zeroing device 2, and the measuring rod 31 are at the first height. Subsequently, the focusing device 7 will focus on the second point. When the focusing device 7 focuses on the second point, the lens barrel 5, the zeroing device 2, and the measuring rod 31 will move up and down synchronously for the second time. When the focusing device 7 completes the focusing of the second point, the lens barrel 5, the zeroing device 2, and the measuring rod 31 are at the second height. At this time, the digital display screen 33 will record the height difference between the first height and the second height. This difference is the height difference between the first point and the second point.

[0021] Simply repeat the above steps to measure the height difference between any two points in the measurement area.

[0022] During measurement, a microscope lens with a small depth of field is selected. A lens with a small depth of field has better repeatability when selecting the point features of the measurement area. At the same time, a high-precision dial indicator 3 is used in conjunction with a focusing device 7. The lens with a small depth of field, the high-precision dial indicator 3, and the focusing device 7 work together to ensure the accuracy of the measurement of the height difference of the points in the vertical direction.

[0023] As a preferred example, the microscope assembly includes an eyepiece 4, a microscope tube 5, an objective lens 6, a focusing device 7, an illumination device 8, and a mounting housing 9. The upper end of the microscope tube 5 is connected to the eyepiece 4, and the lower end is connected to the objective lens 6. The objective lens 6 is disposed inside the mounting housing 9. The focusing device 7 is disposed on the upper outer side of the mounting housing 9 and is connected to the microscope tube 5. The microscope tube 5 can move up and down via the focusing device 7. The illumination device 8 is fixed on the middle outer side of the mounting housing 9 and is a rotatable structure. The mounting housing 9 is fitted onto the outer side of the microscope tube 5, and a slot is provided on one side of the lower part of the mounting housing 9. The microscopic observation system composed of the eyepiece 4, microscope tube 5, objective lens 6, focusing device 7, and illumination device 8 determines the microscopic measurement area through the eyepiece 4, microscope tube 5, and objective lens 6, provides sufficient light to the measurement area through the illumination device 8 for more accurate measurement, and determines the measurement point through the focusing device 7, providing conditions for measuring height differences.

[0024] As a preferred example, the dial indicator 3 includes a measuring rod 31, a lifting rod 32, a digital display screen 33, and a bracket 34. The outer diameter of the measuring rod 31 is smaller than the inner diameter of the lifting rod 32. The lower part of the measuring rod 31 is fitted inside the lifting rod 32, and the upper part of the measuring rod 31 extends out of the lifting rod 32. The bracket 34 includes a connecting part 341 and a supporting part 342. The connecting part 341 is fitted onto the lifting rod 32, and the supporting part 342 is disposed on the bottom surface of the digital display screen 33 and fixedly connected to the lower surface of the digital display screen 33. When measuring height, the measuring rod 31, the zeroing device 2, and the lens barrel 5 are synchronously displaced through the focusing device 7. The height difference between two points in the detection area is the displacement distance of the measuring rod 31. At this time, the digital display screen 33 records the displacement distance of the measuring rod 31, that is, the digital display screen 33 can read the height difference value between the two points in the detection area.

[0025] As a preferred embodiment, the lifting rod 32 is internally provided with an elastic component, which contacts the bottom of the measuring rod 31. The measuring rod 1 moves up and down via the elastic component. During displacement, the measuring rod 1 moves up and down according to the adjustment of the focusing device 7. An elastic component is provided at the bottom of the measuring rod 1, and during measurement, the measuring rod 1 is pressed down to half its position by the elastic component, and the top of the measuring rod 1 is limited by the zeroing device 2. Therefore, when the zeroing device 2 moves upward, the measuring rod 1 moves upward synchronously; when the zeroing device 2 presses down, the measuring rod 1 also presses down synchronously, ensuring measurement accuracy.

[0026] As a preferred embodiment, the top of the measuring rod 31 is provided with a detection contact, which contacts the lower surface of the zeroing device 2. The contact at the top of the measuring rod 31 always maintains contact with the lower surface of the zeroing device 2. During measurement, the measuring rod 31 and the zeroing device 2 move up and down synchronously. After the measurement is completed, the displacement distance of the contact at the top of the measuring rod 31 will be displayed on the digital display screen 33. This distance is the height difference between the two points in the detection area.

[0027] In a preferred embodiment, one end of the locking device 1 is fixed to the outer surface of the fixed housing 9, and the other end is fitted onto the lifting rod 32; the zeroing device 2 is fitted onto the outside of the microscope tube 5. The locking device 1 is fixed to the fixed housing 9 and the lifting rod 32, ensuring that all three components remain stationary during measurement, providing stable measurement and degree conditions for height measurement. The zeroing device 2, fitted onto the outside of the microscope tube 5, ensures that it can move synchronously with the microscope tube 5. The zeroing device 2, in turn, drives the measuring rod 31 to move synchronously, ensuring that during measurement, the digital display screen 33 can smoothly measure the displacement distance of the measuring rod 31, and thus measure the height difference between the two points in the detection area.

[0028] As a preferred embodiment, the bracket 34 is a rotatable structure, and the digital display screen 33 is tilted and mounted on the bracket 34. When the bracket 34 rotates, the digital display screen 33 rotates synchronously with the bracket 34. During measurement, the optimal reading angle can be selected according to the measurement angle. When reading the value, the reading screen 33 is rotated by rotating the bracket 34 to rotate to the most suitable angle, making the reading easier and more convenient, and effectively improving the measurement efficiency.

[0029] As a preferred example, the eyepiece 4 is a 10x eyepiece, and the objective lens 6 is a 10x objective lens. Using a lens with high magnification and shallow depth of field results in a smaller field of view when selecting a detection area, and higher repeatability of features within the same field of view, allowing for better multiple height difference measurements.

[0030] As a preferred embodiment, both the positioning device 1 and the zeroing device 2 are detachable structures. When it is necessary to take this device to different regions, or when the positioning device 1 and the zeroing device 2 are damaged, making the positioning device 1 and the zeroing device 2 detachable structures makes it easier to disassemble and replace them, and also makes it easier to carry this device.
