Description

Technical Field

[0001] This application relates to the field of vibration damping bracket technology, and in particular to a galvanometer bracket with vibration damping function. Background Technology

[0002] Currently, laser processing is commonly used in the manufacturing of small consumer batteries. This technology has significant advantages in processing precision, reaching up to 10 micrometers. However, this precision laser processing is also highly susceptible to machine vibration. In existing technologies, to reduce the impact of vibration, the brackets used to mount the galvanometers are typically made of marble. Marble brackets are expensive to produce and process, while brackets made of ordinary materials cannot achieve the required vibration reduction effect. Utility Model Content

[0003] To address one of the aforementioned technical problems, this application provides a galvanometer support with vibration damping function, comprising a hollow support assembly for mounting the galvanometer, and a flexible component and a vibration damping component disposed within the support assembly. The vibration damping component includes a base, a connecting rod assembly disposed on the base, and mass blocks installed at both ends of the connecting rod assembly. The natural frequency of the vibration damping component is the same as the vibration source frequency. The vibration damping effect is achieved through the resonance of the vibration damping component itself, which can further reduce the vibration experienced by the entire support, thereby reducing the impact of vibration on the galvanometer during operation, improving processing accuracy, and having a simple structure and low manufacturing cost.

[0004] Preferably, the system further includes flexible members disposed within the support assembly, the flexible members abutting against both sides of the base and the inner sidewall of the support assembly. By incorporating flexible members, the overall damping of the structure is increased, thereby achieving a vibration reduction effect to a certain extent.

[0005] Preferably, the bracket assembly includes a mounting base and a hollow square tube disposed on the mounting base. The base is disposed on the mounting base, and the flexible element is embedded between the inner sidewall of the square tube and the base. Two flexible elements are disposed on both sides of the base, and then the square tube is covered on the base and the flexible elements, and the square tube is connected to the mounting base, thereby allowing the flexible element to be embedded between the inner sidewall of the square tube and the base.

[0006] Preferably, a mounting plate is connected to the outer wall of the square tube, and the galvanometer is mounted on the mounting plate. The mounting plate can be fixed to the square tube with bolts, and then the galvanometer is mounted on the mounting plate.

[0007] Preferably, the linkage assembly includes a vertical linkage and a horizontal linkage. One end of the vertical linkage is vertically connected to the base, and the other end is connected to the horizontal linkage. The mass blocks are fixedly disposed at both ends of the horizontal linkage. This ensures that the natural frequency of the vibration damping assembly is the same as the vibration source frequency, achieving a vibration damping effect through self-resonance, thereby further reducing the overall vibration of the structure. This structure is simple and requires no maintenance, upkeep, or disassembly throughout its entire lifespan.

[0008] Preferably, the mass blocks at both ends of the transverse connecting rod are m1 and m2, respectively, and m1 and m2 satisfy |m1-m2| / min(m1,m2)<1%. Preferably, m1 is equal to m2, so that the natural frequency of the vibration damping component is consistent with the vibration source frequency, and the vibration damping effect is achieved through self-resonance, which can further reduce the overall vibration of the structure.

[0009] Preferably, the thickness of the flexible element is 0.5-1 times the thickness of the base. More preferably, the thickness of the flexible element is the same as the thickness of the base.

[0010] Preferably, the flexible component is interference-fitted with the square tube and the base. By incorporating the flexible component, the overall damping of the structure is increased, thereby achieving a vibration reduction effect to a certain extent.

[0011] Preferably, the interference fit of the flexible component is 4%-10% of its thickness. By incorporating the flexible component, the overall damping of the structure is increased, thereby achieving a certain degree of vibration reduction.

[0012] Preferably, the mounting base has mounting holes, and a locking element is inserted into the mounting holes. The locking element can be a bolt, so that after the square tube and the mounting base are hoisted onto the machine platform of the laser equipment, the mounting base is fixed to the machine platform by the locking element.

[0013] Compared with the prior art, the beneficial effects of this application are as follows: This application sets flexible parts and vibration damping components in the support assembly, and the galvanometer is installed on the support assembly. The vibration damping component includes a base, a connecting rod assembly set on the base, and mass blocks installed at both ends of the connecting rod assembly. Through the vibration damping component composed of the base, connecting rod assembly and mass blocks, the natural frequency of the vibration damping component is the same as the vibration source frequency. The vibration damping effect is achieved through the resonance of the vibration damping component itself, which can further reduce the vibration of the support as a whole, thereby reducing the impact of vibration on the galvanometer during operation, improving processing accuracy, and having a simple structure and low manufacturing cost.

[0021] To further understand the content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0022] To address the aforementioned technical problems, this embodiment provides a galvanometer holder with vibration damping function, such as... Figure 1 As shown, the structure includes a hollow support assembly 10, a flexible component 20 disposed within the support assembly 10, and a vibration damping component. The galvanometer is mounted on the support assembly 10. The vibration damping component includes a base 30 and a connecting rod assembly 40 disposed on the base 30. Mass blocks 50 are installed at both ends of the connecting rod assembly 40. The vibration damping component, composed of the base 30, the connecting rod assembly 40, and the mass blocks 50, has the same natural frequency as the vibration source frequency. The vibration damping effect is achieved through the resonance of the vibration damping component itself, which can further reduce the overall vibration of the structure. The structure is simple and has low manufacturing cost, reduces the impact of vibration on the galvanometer during operation, and improves processing accuracy.

[0023] Specifically, it also includes flexible components 20 disposed within the support assembly 10. These flexible components 20 abut against both sides of the base 30 and against the inner wall of the support assembly 10. By incorporating the flexible components 20, the overall damping of the structure is increased, thereby achieving a vibration reduction effect to a certain extent.

[0024] Furthermore, the support assembly 10 includes a mounting base 11 and a square tube 12 disposed on the mounting base 11. The square tube 12 has a hollow structure. A base 30 is disposed on the mounting base 11. Two flexible members 20 are disposed on both sides of the base 30. The square tube 12 is then placed over the base 30 and the flexible members 20, and the square tube 12 is connected to the mounting base 11, thereby allowing the flexible members 20 to be embedded between the inner wall of the square tube 12 and the base 30. In some embodiments, the flexible member 20 may be a rubber block or other flexible object with resilience.

[0025] Furthermore, the flexible component 20 is interference-fitted with the square tube 12 and the base 30. During installation, the interference fit of the flexible component 20 is 4%-10% of its thickness. By incorporating the flexible component, the overall damping of the structure is increased, thereby achieving a vibration reduction effect to a certain extent. The thickness of the flexible component 20 is 0.5-1 times the thickness of the base 30; preferably, the thickness of the flexible component 20 is the same as the thickness of the base 30.

[0026] Furthermore, in the above-described scheme, a mounting plate 60 is connected to the outer wall of the square tube 12, and the galvanometer is mounted on the mounting plate 60. In some embodiments, the mounting plate 60 can be fixed to the square tube 12 with bolts, and then the galvanometer is mounted on the mounting plate 60.

[0027] In the above scheme, the vibration damping component includes a base 30, a connecting rod assembly 40 mounted on the base 30, and mass blocks 50 installed at both ends of the connecting rod assembly 40. The connecting rod assembly 40 includes a vertical connecting rod 41 and a horizontal connecting rod 42. One end of the vertical connecting rod 41 is vertically connected to the base 30, and the other end of the vertical connecting rod 41 is connected to the horizontal connecting rod 42. The mass blocks 50 are fixedly mounted at both ends of the horizontal connecting rod 42. Thus, the base 30, connecting rod assembly 40, and mass blocks 50 constitute the vibration damping component, ensuring that the natural frequency of the vibration damping component is the same as the vibration source frequency. Vibration damping is achieved through the resonance of the vibration damping component itself, further reducing the overall vibration of the structure. This structure is simple and requires no maintenance, upkeep, or disassembly throughout its entire lifespan.

[0028] Furthermore, the mass blocks 50 at both ends of the transverse connecting rod 42 are m1 and m2, respectively, and m1 and m2 satisfy |m1-m2| / min(m1,m2)<1%. Preferably, m1 is equal to m2.

[0029] Specifically, in the above scheme, the natural frequency f1 of the vibration damping component is the same as the vibration source frequency f2, that is... In the formula, l is the length of the transverse connecting rod 42, E is the elastic modulus of the transverse connecting rod 42 and the vertical connecting rod 41, and I is the moment of inertia of the connecting rod section. Furthermore, the natural frequency of the vibration damping component is the same as the vibration source frequency, achieving a vibration reduction effect through its own resonance, thereby further reducing the overall vibration of the structure.

[0030] Furthermore, a lifting lug 14 is threadedly connected to the top of the square tube 12. The lifting lug 14 is installed at a diagonal position on the top of the square tube 12 by means of threaded connection, so as to facilitate the hoisting of the square tube 12 onto the machine platform of the laser equipment.

[0031] Furthermore, the mounting base 11 has a mounting hole, and a locking element 13 is inserted into the mounting hole. For example, the locking element 13 can be a bolt. After the square tube 12 and the mounting base 11 are hoisted onto the machine platform of the laser equipment, the mounting base 11 is fixed to the machine platform by the locking element 13.

[0032] In summary, in one or more embodiments of this application, the solution incorporates flexible components and vibration damping components within a support assembly. A galvanometer is mounted on the support assembly. The vibration damping component includes a base, a connecting rod assembly mounted on the base, and mass blocks mounted at both ends of the connecting rod assembly. The flexible components abut against both sides of the base and the inner wall of the support assembly. By incorporating flexible components, the overall damping of the structure is increased, thereby achieving a vibration reduction effect to a certain extent. Furthermore, the vibration damping component, composed of the base, connecting rod assembly, and mass blocks, has the same natural frequency as the vibration source frequency. Vibration reduction is achieved through the resonance of the vibration damping component itself, further reducing the overall vibration of the structure. The structure is simple, has low manufacturing cost, reduces the impact of vibration on the galvanometer during operation, and improves processing accuracy.

[0033] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
