Detailed Implementation
[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0033] Figure 1 This is a schematic diagram of the structure of a spectrometer mirror adjustment device according to an embodiment of the present invention. Figure 2 for Figure 1 The diagram shown is a structural schematic of the spectrometer's mirror adjustment device from another angle, combined with... Figure 1 and Figure 2 As shown, the spectrometer mirror adjustment device may include:
[0034] The system comprises a support assembly 1, a reflector 2, a first adjustment assembly 3, and four adjustment bolts 4. The support assembly 1 includes a first support 11, a second support 12, and a third support 13. The first support 11 and the third support 13 are respectively disposed on opposite sides of the second support 12. The first support 11 has a groove in which the reflector 2 is installed.
[0035] The first adjustment assembly 3 includes an adjustment rod 31. The second bracket 12 has a first through hole 121, and the third bracket has a second through hole 131. The adjustment rod 31 passes through the second through hole 131 and the first through hole 121 and is connected to the side of the first bracket 11 away from the reflector 2. The third bracket 13 is provided with four screw holes, and four adjustment bolts 4 pass through the four screw holes respectively and abut against the side of the second bracket 12 away from the first bracket 11. The adjustment rod 31 is perpendicular to the mirror extension direction of the reflector, and the four adjustment bolts 4 are also perpendicular to the mirror extension direction of the reflector.
[0036] The adjusting rod 31 can move within the second through hole 131 and the first through hole 121, thereby increasing the spatial adjustment range of the reflector.
[0037] In summary, in the spectrometer reflector adjustment device provided by this embodiment, the first and third supports are respectively disposed on opposite sides of the second support. The reflector is installed in the groove of the first support. The adjustment rod passes through the first through hole on the second support and the second through hole on the third support, and connects to the side of the first support away from the reflector. Four adjustment bolts pass through four screw holes and abut against the side of the second support away from the first support. The diameter of the first through hole is larger than the diameter of the adjustment rod, allowing the adjustment rod to tilt and swing in any direction within the first through hole, thereby adjusting the angle of the reflector. The diameter of the second through hole is the same as the diameter of the adjustment rod, allowing the adjustment rod to move back and forth between the first and second through holes. The adjustment rod can move the reflector located in the groove of the first support through the second through hole, thereby increasing the spatial adjustment range of the reflector. This solves the problem of limited adjustment range of the reflector in related technologies and achieves the effect of improving the spatial adjustment range of the reflector.
[0038] Optionally, such as Figure 1 As shown, the first adjustment assembly also includes a set screw 32. A set screw hole is provided on the third bracket 13, connecting the outer peripheral surface of the third bracket 13 and the second through hole. The set screw 32 passes through the set screw hole and abuts against the adjustment rod 31. The set screw is used to fix the adjustment rod 31. When the angle of the reflector needs to be adjusted, the set screw 32 is loosened, and the position of the adjustment rod 31 in the first and second through holes is moved until the position of the reflector is determined. Then, the set screw is tightened until the set screw 32 abuts against the outer peripheral surface of the adjustment rod 31 to fix the adjustment rod 31. In this embodiment of the invention, there are two set screws, each disposed in one of the two set screw holes. The number of set screws can also be one or more; this embodiment of the invention does not limit the number of set screws.
[0039] Optionally, such as Figure 1 As shown, the second bracket 12 includes a vertical plate 122 and a bottom plate 123. The vertical plate 122 and the bottom plate 123 are an integral structure and are perpendicular to each other. The first through hole is located on the vertical plate 122. The bottom plate 123 is provided with at least two mounting holes 124. The second bracket 12 can be installed in the optical platform or mounting base of the spectrometer through the two mounting holes 124, thereby fixing the spectrometer reflector adjustment device in the spectrometer.
[0040] Figure 3 for Figure 1 A schematic diagram of the spectrometer's reflector adjustment device from another angle; Figure 4 for Figure 3 A partial structural schematic diagram of the spectrometer's mirror adjustment device is shown. Figure 4 A side view of the first bracket 11 near the second bracket 12 is provided, in conjunction with... Figure 3 and Figure 4 As shown, the first adjustment assembly also includes four second screws 331 and an annular plate 33. The annular plate 33 is located at the end where the adjustment rod 31 connects to the first bracket 11, and the axis of the annular plate 33 is parallel to the length direction of the adjustment rod 31. The annular plate 33 and the adjustment rod 31 are an integral structure. The annular plate 33 has four through holes, which are evenly arranged around the adjustment rod 31. The first bracket 11 has four threaded holes. The four second screws 331 pass through the four through holes on the annular plate 33 and are threadedly connected to the four threaded holes on the first bracket 11. The four second screws 331 are perpendicular to the mirror extension direction of the reflector, and the even arrangement of the four second screws 331 makes the connection between the first bracket and the adjustment rod more stable.
[0041] Optionally, this utility model also provides another spectrometer mirror adjustment device, wherein the first adjustment component further includes a first screw, the end face of the adjustment rod connected to the first bracket has a central screw hole, the first screw passes through the through hole on the first bracket and is threadedly connected to the central screw hole on the adjustment rod. The above connection method is simple and further simplifies the structure of the spectrometer mirror adjustment device.
[0042] Figure 4 for Figure 1 The diagram shows another angle of the spectrometer's reflector adjustment device, as shown below. Figure 4 As shown, the adjusting rod 31 is a rotating shaft, and the first through hole (not shown in the figure) and the second through hole 131 are circular through holes.
[0043] Alternatively, in another embodiment, the first through hole and the second through hole are square through holes, and the adjusting rod is a square rod. The area of the first through hole is larger than the area of the second through hole, and the area of the second through hole is similar to the cross-sectional area of the adjusting rod, allowing the square rod to move back and forth between the first and second through holes.
[0044] Alternatively, the adjusting rod can be a telescopic adjusting rod, which includes an outer rod and an inner rod that can retract into the outer rod. The inner rod has external threads, and the outer rod has internal threads. By rotating the inner or outer rod, the interaction of the threads achieves telescopic movement, thereby moving the reflector. After adjusting to the appropriate length, tightening the set screw increases the friction between the inner and outer tubes, thus fixing the position of the telescopic rod. Alternatively, the telescopic adjusting rod can also be an internal snap-lock type telescopic adjusting rod with an eccentric lock, or a telescopic adjusting rod including a locking component; this invention does not limit the specific type.
[0045] Optionally, such as Figure 2 As shown, the diameter of the first through hole 121 is larger than the diameter of the adjusting rod 31, and the diameter of the second through hole 131 is the same as the diameter of the adjusting rod 31. Since the diameter of the first through hole 121 is larger than the diameter of the adjusting rod 31, the adjusting rod 31 can tilt and swing in any direction within the first through hole 121, thereby adjusting the tilt angle of the reflector. Since the diameter of the second through hole 131 is the same as the diameter of the adjusting rod 31, the adjusting rod 31 can move back and forth between the first through hole 121 and the second through hole 131.
[0046] like Figure 5As shown, four screw holes are evenly arranged around the second through hole on the third bracket 13, and four adjusting bolts 4 are evenly arranged around the adjusting rod, passing through the four screw holes respectively. The center line of the four adjusting bolts 4 forms a cross shape in the vertical plane. By adjusting the four adjusting bolts 4, the tilt angle of the third bracket 13 can be adjusted, thereby causing the adjusting rod to change angle. Since the diameter of the second through hole is larger than the diameter of the adjusting rod, the adjusting rod has sufficient range of motion in the second through hole. The movement of the adjusting rod causes the angle of the reflector on the first bracket to change. In addition, there is a gap between the second bracket and the third bracket, the gap distance is greater than or equal to 2 mm, which provides sufficient adjustment space for the adjusting bolts.
[0047] In addition, such as Figure 1 As shown, the first and third supports are circular. The first and third supports can also be square. The four adjusting bolts can be evenly distributed on the four sides of the third support. The specific shapes of the first and third supports are not limited in this embodiment of the invention.
[0048] In summary, the spectrometer reflector adjustment device provided in this embodiment of the present invention has a first bracket and a third bracket respectively disposed on opposite sides of a second bracket. The reflector is installed in a groove in the first bracket. An adjustment rod passes through a first through hole on the second bracket and a second through hole on the third bracket, connecting to the side of the first bracket away from the reflector. The adjustment rod can move along its length in the second and first through holes, thereby moving the reflector located in the groove of the first bracket. Four adjustment bolts pass through four screw holes and abut against the side of the second bracket away from the first bracket. Any adjustment bolt can be tightened or loosened to adjust the angle of the reflector, increasing the spatial adjustment range of the reflector. Furthermore, the bracket assembly, the first adjustment assembly, and the second adjustment assembly in this application are all located on the non-reflective side of the reflector, facilitating the adjustment of the reflector without occupying the space on the front of the reflector, thus not obstructing light from entering or exiting the reflector.
[0049] According to the above embodiments, such as Figure 5 As shown, this utility model provides an adjustment process for a spectrometer mirror adjustment device. Using a spatial rectangular coordinate system as an example, the direction of movement of the adjustment rod is perpendicular to the plane of the paper. In the vertical plane, among the four adjustment screws, the vertical adjustment screw represents the x-axis, and the horizontal adjustment screw represents the y-axis. Specifically:
[0050] Loosen the set screw that secures the rotating shaft, and move the adjusting rod in a direction perpendicular to the paper until the reflector is in the desired position.
[0051] Using a suitable tool (such as a screwdriver or wrench), rotate the adjusting screw. To increase the x-axis angle, tilt the axis in the x-axis direction by rotating the upper bolt clockwise while simultaneously rotating the lower adjusting bolt counterclockwise. To decrease the x-axis angle, perform the opposite operation. When rotating the bolts, do so slowly and evenly, avoiding large rotations each time. It is recommended to rotate 1 / 4 turn or less each time to precisely control the angle adjustment.
[0052] Use a tool to rotate the adjusting bolts on the left and right sides to adjust the y-axis angle. To tilt the adjusting rod to the left along the y-axis, increasing the y-axis angle, rotate the left adjusting bolt clockwise and the right adjusting bolt counterclockwise; conversely, to decrease the y-axis angle, rotate the left bolt counterclockwise and the right bolt clockwise. Similarly, rotate the bolts slowly and evenly, with small rotations each time.
[0053] After adjusting the position, tighten the set screw to fix the adjusting rod.
[0054] The above adjustment process allows you to first determine the position of the reflector on the z-axis without fixing the adjusting rod, and then make fine adjustments using the adjusting bolts. This not only expands the adjustment range of the reflector but also improves the adjustment efficiency.
[0055] In this invention, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.
[0056] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
