In this way, when the aircraft is flying and turning, the T-shaped stage 202 can move along the X-axis direction following the two X-axis moving blocks 2011, and meanwhile, under the elastic force action of the second elastic member 2020 and the fourth elastic member 2022, a buffering action along the X-axis direction can be realized; the T-shaped stage 202 can move along the Y-axis direction following the two Y-axis moving blocks 2012, and at the same time, under the elastic force action of the first elastic member 2019 and the third elastic member 2021, a buffering action along the Y-axis direction can be realized; when the aircraft ascends and descends, the T-shaped stage 202 can move along the Z-axis direction along with the four Z-axis moving blocks 2013, and meanwhile, under the elastic force action of the fifth elastic element 2023, a buffering action along the Z-axis direction can be realized.

Of course, according to actual needs, the first elastic element 2019, the second elastic element 2020, the third elastic element 2021, the fourth elastic element 2022, and the fifth elastic element 2023 may be set as compression springs, and a preset pre-tightening force is set when any one of the springs is installed, that is, when the triaxial anti-vibration unit 201 is in an original state, any one of the springs is in a compressed state.

Meanwhile, in order to facilitate the stability of movement, when the optical axis is connected with the T-shaped carrying table 202 or the moving block in a penetrating manner, linear bearings are arranged in the through holes of the T-shaped carrying table 202 and the through holes of the moving block, so that the movement is facilitated in flexibility and stability. And a stop screw is arranged on any moving block and used for limiting the corresponding optical axis so as to prevent the optical axis from moving along the axial direction.

In summary, the three-axis anti-vibration unit 201 adopts 32 springs as the buffer medium, and the double-layer X, Y axis movement is matched with the single-layer Z axis movement to achieve the universal anti-vibration effect. That is, the three-axis anti-vibration unit 201 realizes parallel, vertical, and oblique movement of the T-shaped stage 202 and the sensor assembly 100 through the double parallel optical axes in the X, Y axis direction structure, as shown in fig. 5; the vertical movement of the T-shaped stage 202 and the sensor assembly 100 is realized through a single layer of parallel optical axes in the Z-axis direction, as shown in fig. 6, and at the same time, the multi-axis vibration resistance is achieved through two springs on each optical axis.

The triaxial anti-vibration unit 201 is assembled in a manner including: the sensor assembly 100 is fixed on a T-shaped carrying platform 202 through bolts, an X-axis moving block 2011, a first optical axis 2014, a Y-axis moving block 2012 and a second optical axis 2015 are respectively installed on the T-shaped carrying platform 202, linear bearings need to be installed at positions where the optical axes pass through for structures needing to move inside, springs with lengths matched with each other need to be installed at two ends and stop screws need to be installed at the ends of the optical axes for fastening when each group of optical axes are installed, a third optical axis 2016, a fourth optical axis 2017, a Z-axis moving block 2013, springs and linear bearings with lengths corresponding to the optical axes are installed after the installation is finished, a fifth optical axis 2018 is installed in the Z-axis moving blocks 2013 at four corners after the installation is finished, an optical axis fixing bearing 1014 and a spring are installed on the fifth optical axis 2018, and finally the anti-vibration module is integrally packaged in a housing assembly.

It should be noted that the anti-vibration module with the single-axis anti-vibration unit 101 and the anti-vibration module with the three-axis anti-vibration unit 201 can be quickly replaced according to the actual working environment. Specifically, under different operational environment, can temporarily resist the internal component of vibration module and change in order to realize the single/multiaxis of fast switch over anti vibration structure, the change step is: the sensor assembly 100 is detached from the plate-shaped stage 102, then the Z-axis moving block 2013 in the single-axis anti-vibration unit 101 is detached in such a manner as to leave the guide optical axis 1012, the guide linear bearing 1013, and the optical axis fixing bearing 1014, and then the sensor assembly 100 is mounted to the T-shaped stage 202 (the T-shaped stage 202 is mounted in advance to the three-axis anti-vibration unit 201 lacking the fifth optical axis 2018), and the remaining parts are re-filled into the partially assembled three-axis anti-vibration unit 201 to constitute the complete three-axis anti-vibration unit 201, at this time, the guide optical axis 1012 is applied to the three-axis anti-vibration unit 201 as the fifth optical axis 2018, the guide linear bearing 1013 is mounted between the fifth optical axis 2018 and the Z-axis moving block 2013, and as shown in fig. 7, finally, the housing assembly is packaged again, and is self-corrected in a planar position.

Of course, the structure of the housing assembly for housing the anti-vibration module having the single-axis anti-vibration unit 101 and the anti-vibration module having the triaxial anti-vibration unit 201 is the same, that is, the anti-vibration module having the single-axis anti-vibration unit 101 and the anti-vibration module having the triaxial anti-vibration unit 201 may share the same housing assembly, so that the efficiency of mounting and dismounting may be greatly improved.

It should be noted that, the switching of the internal movement modes of the anti-vibration module depends on the actual environment of the application, and the anti-vibration module with the single-axis anti-vibration unit 101 is mainly suitable for the situation that reciprocating, nonlinear and high-frequency vibration is easily generated on a single industrial axis or single surface, and the damper 1011 with long service life and stable performance is selected under the situation of relatively simplified structure and on the premise of having a large assembly space; in a complex vibration environment or under the condition of multi-axial acceleration, the single-axis anti-vibration unit 101 can only move in the Z-axis direction, which results in poor anti-vibration effect, and in this environment, the anti-vibration module with the single-axis anti-vibration unit 101 can be quickly replaced by the anti-vibration module with the three-axis anti-vibration unit 201, so that the reciprocating universal anti-vibration effect can be realized through the double-layer XY axis and the single Z axis.
