Description

Technical Field

[0001] This utility model relates to the field of measuring support technology, and more specifically, to a shockproof optical measuring instrument support frame. Background Technology

[0002] Optical measuring instrument support frames are specialized mechanical structures used to fix, position, and stabilize optical measuring equipment (such as microscopes, interferometers, spectrometers, etc.). Their core function is to ensure that the relative position between the instrument and the object being measured remains highly stable during the measurement process, so as to eliminate the influence of environmental vibration, temperature changes, and mechanical stress on the measurement accuracy. They are an indispensable basic equipment in precision optical measurement, scientific research experiments, and industrial inspection, and directly affect the repeatability, accuracy, and reliability of the measurement system.

[0003] For example, Chinese patent disclosure: A flexibly adjustable optical measuring bracket, application number: CN202021638717.6, includes a base, a fixed cylinder fixedly connected to the top of the base, a lead screw fixedly connected to the inner bottom wall of the fixed cylinder, a drive sleeve threadedly connected to the lead screw, a lifting sleeve rotatably connected to the drive sleeve, the left and right sides of the lifting sleeve contacting the fixed cylinder, a lifting block fixedly connected to the top of the lifting sleeve, a control rod slidably connected to the inner side of the lifting block, and evenly distributed fixing holes on the top of the drive sleeve. This utility model can adjust the height of the bracket and can adjust the horizontal and vertical angles of the measuring machine by controlling the bracket, making the bracket adjustment function more flexible and diverse, and convenient for operators to perform inspections.

[0004] However, in the field of precision optical measurement, the vibration isolation performance of the instrument support frame directly affects the measurement accuracy. Although traditional hydraulic vibration damping supports can dissipate vibration energy through oil damping, their damping channels are mostly fixed designs. When changing to measuring instruments of different weights, the fixed damping settings may not be able to match the new load, resulting in a significant decrease in vibration isolation performance. Furthermore, when the vibration source in the surrounding environment changes, such as changes in vibration frequency or amplitude, traditional support frames are also difficult to adapt to, and are prone to excessive shaking, which in turn affects the accuracy and stability of optical measurements and cannot meet the precision measurement requirements under complex working conditions. Utility Model Content

[0005] The main objective of this invention is to provide a shock-resistant optical measuring instrument support frame, which can effectively solve the problem in the background art where the vibration isolation performance of the instrument support frame directly affects the measurement accuracy in the field of precision optical measurement. Although traditional hydraulic vibration damping supports can dissipate vibration energy through oil damping, their damping channels are mostly fixed designs. When changing measuring instruments of different weights, the fixed damping settings may not be able to match the new load, resulting in a significant decrease in vibration isolation performance. Furthermore, when the vibration source in the surrounding environment changes, such as changes in vibration frequency or amplitude, traditional support frames are also difficult to adapt to, and are prone to excessive shaking, which in turn affects the accuracy and stability of optical measurements and cannot meet the precision measurement requirements under complex working conditions.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a shockproof optical measuring instrument support frame, including a base, an oil groove and a spring are provided on the base, an annular groove is provided between the oil groove and the spring, the annular groove and the oil groove are connected through a flow port, a sliding groove is provided on one side below the flow port, a stop block is slidably provided in the sliding groove, a sealing layer is fixedly provided on the inner wall surface of the sliding groove, an adjustment component is provided on one side directly below the stop block, a piston is slidably provided in the oil groove, a support column is fixedly provided on the piston, a placement plate is fixedly provided on one side of the top of the support column, a placement groove is provided on the placement plate, and several guide sliding columns are fixedly provided on the outer wall surface of one side below the placement plate.

[0007] Preferably, the two sides of the spring are fixedly connected to the base and the placement plate, respectively.

[0008] Preferably, the guide slide is slidably connected to the base, and the oil groove and the annular groove are respectively filled with damping oil and compressed air.

[0009] Preferably, the adjustment component includes a component base, on which a threaded groove is provided, and a threaded post is provided in the threaded groove. A knob is fixedly provided at the end of the threaded post away from the stop block.

[0010] Preferably, the component base is fixedly mounted on the base.

[0011] Preferably, the end of the threaded post away from the knob is rotatably connected to the stop.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) The present invention first installs the optical measuring instrument in the placement slot, and then moves the stop block closer to or further away from the placement plate by adjusting the component. By moving the stop block, the flow rate of the outlet can be adjusted according to the weight of the optical measuring instrument or the vibration source of the surrounding environment. Then, when vibration occurs, the spring deforms, and the oil in the oil tank is squeezed by the piston and moves from the outlet to the ring groove. The damping force generated when flowing through the outlet and the spring consume the vibration energy, which can flexibly adapt to the changing load and working conditions, and avoid the vibration isolation performance from dropping significantly or excessive shaking due to changes in load or environment.

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. 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 of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0020] like Figures 1 to 3As shown, a shockproof optical measuring instrument support frame includes a base 1, on which an oil groove 2 and a spring 3 are provided. An annular groove 4 is provided between the oil groove 2 and the spring 3. The annular groove 4 and the oil groove 2 are connected through an outlet 5. A sliding groove 6 is provided on one side below the outlet 5. A stop block 7 is slidably provided in the sliding groove 6. A sealing layer 8 is fixedly provided on the inner wall surface of the sliding groove 6. An adjusting component 9 is provided on one side directly below the stop block 7. A piston 10 is slidably provided in the oil groove 2. A support column 11 is fixedly provided on the piston 10. A placement plate 12 is fixedly provided on one side of the top of the support column 11. A placement groove 13 is provided on the placement plate 12. A plurality of guide sliding columns 14 are fixedly provided on the outer wall surface of one side below the placement plate 12.

[0021] like Figure 4 As shown, in another embodiment of the present invention, the adjustment component 9 includes a component base 901, a threaded groove 902 is provided on the component base 901, a threaded post 903 is provided in the threaded groove 902, and a knob 904 is fixedly provided on the end of the threaded post 903 away from the stop block 7.

[0022] When it is necessary to move the stop block 7, first rotate the threaded column 903 by the knob 904, and use the threaded column 903 to move the stop block 7 closer to or further away from the placement plate 12. By moving the stop block 7, the flow rate of the outlet 5 can be adjusted. By adjusting the size of the outlet 5, the optimal damping ratio required for shock absorption can be rematched in real time or in advance.

[0023] The working principle of this shockproof optical measuring instrument support frame:

[0024] In use, the optical measuring instrument is first installed in the placement slot 13. Then, the knob 904 is turned to rotate the threaded column 903. The threaded column 903 moves the stop 7 closer to or further away from the placement plate 12. By moving the stop 7, the flow rate of the outlet 5 can be adjusted according to the weight of the optical measuring instrument or the vibration source in the surrounding environment. When vibration occurs, the spring 3 deforms, and the oil in the oil tank 2 is squeezed by the piston 10 and moves from the outlet 5 to the annular groove 4. The damping force generated when flowing through the outlet 5 and the spring 3 consume the vibration energy. It can flexibly adapt to changing loads and working conditions, and avoid a significant decrease in vibration isolation performance or excessive shaking due to changes in load or environment.

[0025] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
