Description

Technical Field

[0001] This utility model relates to the field of optomechanical crossbeam technology, specifically to an optomechanical crossbeam with a shock-absorbing mechanism. Background Technology

[0002] In optomechanical equipment, the optomechanical beam is an important supporting component, and its stability has a crucial impact on the optical performance and working accuracy of the equipment.

[0003] Existing optical engine beams are susceptible to external vibrations and vibrations generated during operation. For example, when the optical engine equipment is installed in a working environment with slight vibrations, or when the vibrations generated by the operation of internal components such as motors are transmitted to the beam, the beam vibrations can cause changes in the relative positions of the optical elements inside the optical engine equipment, thereby affecting the stability of the optical path, reducing the imaging quality and measurement accuracy of the equipment. Moreover, long-term exposure to vibration can easily cause the connection between the optical engine beam and other components to loosen, shortening the service life of the equipment.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Please see Figure 1-3 A type of optomechanical crossbeam with a shock-absorbing mechanism includes a crossbeam body 1, a slide rail 2 fixedly installed on the top of the crossbeam body 1, and mounting seats 3 fixedly connected to both sides of the bottom of the crossbeam body 1. The top of the mounting seat 3 is provided with a mounting groove 4 and a hollow groove 6. A shock-absorbing component 5 is provided inside the mounting groove 4, and an anti-resonance component 7 is provided inside the hollow groove 6. The shock-absorbing component 5 and the anti-resonance component 7 work together. By setting the shock-absorbing component 5, the crossbeam body 1 can be shock-absorbing. By setting the anti-resonance component 7, resonance caused by the reciprocating motion of the shock-absorbing component 5 can be avoided.

[0021] The vibration damping component 5 includes a hollow rod 51 embedded in the inner wall of the mounting groove 4, a transmission rod 52 slidably connected to the top of the hollow rod 51, a top plate 53 fixedly connected to the top of the transmission rod 52, and a bottom plate 54 fixedly connected to the bottom of the transmission rod 52. A first spring 55 is provided in the inner cavity of the hollow rod 51. The two ends of the first spring 55 are fixedly connected to the top of the inner cavity of the hollow rod 51 and the top of the bottom plate 54, respectively. The first spring 55 is sleeved on the surface of the transmission rod 52. The bottom plate 54 is slidably connected to the inside of the hollow rod 51, and the top plate 53 is slidably connected to the inside of the mounting groove 4. When vibration occurs, the vibration is transmitted through the top plate 53, the transmission rod 52, and the bottom plate 54, causing the first spring 55 to deform and absorb the vibration energy, thereby playing a role in vibration damping.

[0022] Furthermore, a limiting groove 56 is provided on the inner wall of the mounting groove 4. A limiting slider 57 is slidably connected to the inner cavity of the limiting groove 56. The limiting slider 57 is fixedly connected to the surface of the top plate 53. By sliding the limiting slider 57 in the limiting groove 56, the movement direction of the top plate 53 can be guided when it receives vibration. An annular groove 58 is provided on the surface of the bottom plate 54. A sealing ring 59 is sleeved inside the annular groove 58 to increase the sealing performance of the bottom plate 54. A damping rubber sleeve 510 is fixedly sleeved on the surface of the cavity rod 51. A fixing groove 511 is provided on the inner wall of the mounting groove 4 relative to the position of the damping rubber sleeve 510. By setting the damping rubber sleeve 510, a shock absorption function can be achieved, and the cavity rod 51 can also be protected.

[0023] Preferably, the anti-resonance component 7 includes a positioning plate 71 fixedly connected to the top of the inner cavity of the hollow groove 6, a second spring 72 fixedly connected to the bottom of the positioning plate 71, and an adhesive plate 73 fixedly connected to the bottom of the second spring 72. The surface of the adhesive plate 73 is in frictional contact with the inner wall of the hollow groove 6. The mounting base 3 has a through groove 74 inside, with both ends of the through groove 74 penetrating the hollow groove 6 and the cavity rod 51, respectively. A connecting pipe 75 is fixedly sleeved on the inner wall of the through groove 74. The adhesive plate 73, the connecting pipe 75, and the cavity rod 51 are all connected together. A pressure-stabilizing cavity is formed between the first spring 55 and the base plate 54, and the cavity is filled with damping fluid 76. When the first spring 55 absorbs vibration energy through deformation, it can squeeze the damping fluid 76. The damping fluid 76 surges into the positioning plate 71 within the connecting pipe 75. At this time, the second spring 72 compresses the bonding plate 73 and moves it upward. Through the viscous resistance of the damping fluid 76, the energy of the reciprocating vibration of the first spring 55 can be consumed, preventing resonance from occurring during its reciprocating motion. At the same time, the energy of the reciprocating vibration of the second spring 72 can also be offset.

[0024] Working principle: When the main body 1 of the crossbeam vibrates, the vibration force can be transmitted under the action of the top plate 53. Under the connection of the transmission rod 52, the bottom plate 54 can move downward, and the first spring 55 is stretched. In this way, the vibration energy can be absorbed by the deformation force of the first spring 55, thus playing a role in shock absorption. When the bottom plate 54 moves downward, it can squeeze the damping liquid 76 in the pressure stabilizing chamber, so that the damping liquid 76 flows into the interior of the hollow groove 6 through the connecting pipe 75. By setting the second spring 72 and the bonding plate 73, when the damping liquid 76 is squeezed, the bonding plate 73 moves upward. In this way, the energy of the reciprocating vibration of the first spring 55 and the second spring 72 can be consumed by the viscous resistance of the damping liquid 76, thus avoiding resonance of their reciprocating motion.
