Description

Technical Field

[0001] This utility model relates to the field of vibration reduction technology, and in particular to a vibration reduction component. Background Technology

[0002] In industrial production, mechanical equipment operation, and the installation of various precision instruments, vibration damping components are key components that suppress vibration transmission and ensure equipment stability. Their performance directly affects the operating accuracy, service life, and safety of the equipment.

[0003] Currently, most vibration damping devices on the market use rubber pads. A rubber pad is placed between two mounting components and then locked in place with screws, utilizing the compression deformation of the rubber material to absorb energy and reduce vibration. However, in practical applications, when the screws are tightened, the rubber pads become excessively compressed, significantly reducing their elastic restoring ability, decreasing rebound force, and resulting in poor vibration damping performance.

[0004] To improve vibration damping, some devices use composite damping structures, typically consisting of upper and lower washers connected by two steel pipes in the middle. While these composite structures offer significantly improved damping performance compared to a single rubber pad, their complexity leads to a substantial increase in the number of parts, requiring user assembly, increasing installation difficulty, and making parts prone to loss and inconvenient to use. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a shock-absorbing component that combines excellent shock absorption performance with convenient installation.

[0006] Therefore, the technical solution of this utility model is: a shock-absorbing component, installed on the part to be fixed, including a first shock absorber, a second shock absorber, a bushing, and rivets; both the first and second shock absorbers are annular structures, the first shock absorber has a hollow positioning post on the side facing the second shock absorber, and the bushing is placed inside the hollow positioning post; the first and second shock absorbers are respectively located on both sides of the part to be fixed, and the hollow positioning post passes through the assembly hole of the part to be fixed and is inserted into the second shock absorber; both sides of the first and second shock absorbers are provided with limiting parts and are locked and fixed by rivets.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the limiting part of the first shock absorber and the second shock absorber is provided with limiting holes; the rivet passes through the limiting hole of the first shock absorber, the through hole of the part to be fixed and the limiting hole of the second shock absorber in sequence, and is locked and fixed.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the hollow positioning column is provided with a mounting hole that penetrates the first shock absorber in the middle, the bushing is placed in the mounting hole and is interference-fitted with the mounting hole.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the length of the bushing is less than the depth of the mounting hole.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the first damping component and the second damping component are made of rubber, and the bushing is made of metal.

[0011] The first and second damping components of this invention are located on both sides of the component to be fixed, forming a bidirectional damping layout. When vibration is transmitted from one side of the component to be fixed, it first passes through the initial energy absorption of the damping component on one side, and the remaining vibration energy is then absorbed a second time by the damping component on the other side. This double superposition further weakens the vibration transmission efficiency and improves the overall damping effect.

[0012] Meanwhile, the metal bushing is inserted into the mounting hole of the first shock absorber through an interference fit. The first and second shock absorbers are fixed to the part to be fixed by rivets. When the equipment leaves the factory, the shock absorber assembly can be directly installed on the part to be fixed. After receiving the equipment, the user can place the mounting bracket on one side of the first shock absorber and tighten it with bolts, nuts, and washers. There is no need to install the shock absorber assembly separately, simplifying the installation process and reducing the risk of losing parts of the shock absorber assembly.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The first and second shock absorbers are fixed to the positions on the equipment by rivets. The bushing is interference-fitted with the first shock absorber, so that all the parts of the shock absorber assembly are installed before leaving the factory, eliminating the need for complicated assembly by the user and effectively avoiding the risk of losing parts. The operation steps are simple and the assembly efficiency is improved.

[0014] The dual rubber damping structure of the first and second damping components, combined with the limiting effect of the bushing, prevents the rubber from being excessively compressed. The bushing and the mounting hole of the first damping component are interference-fitted and the length is less than the depth of the mounting hole, which prevents the rubber damping component from being excessively compressed. It also provides reasonable deformation space for the damping component, ensuring that the rubber material always maintains good elastic recovery ability, continuously plays the role of energy absorption and damping, and greatly improves the damping stability and service life.

Detailed Implementation

[0017] In the description of this utility model, it should be noted that the directional terms such as "center", "horizontal (X)", "longitudinal (Y)", "vertical (Z)", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this utility model.

[0018] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" or "a number" means two or more, unless otherwise explicitly specified.

[0019] See the attached drawings. The shock absorption component described in this embodiment is installed on the component to be fixed 5 (the component to be fixed 5 can be fixed at the corresponding position of the equipment and device), and the fixing surface of the component to be fixed 5 is provided with assembly holes 51 and through holes 52 on both sides.

[0020] The damping assembly consists of a first damping element 1, a second damping element 2, a bushing 3, and rivets 4. The first damping element 1 is an overall ring structure, with a protruding hollow positioning post 11 on one side. The hollow positioning post 11 has a mounting hole 12 penetrating through the first damping element 1. First limiting portions 13 extend outward from both sides of the first damping element 1, and first limiting holes 14 are provided on the first limiting portions 13. The second damping element 2 is also an ring structure, with second limiting portions 21 extending outward from both sides. Second limiting portions 21 have second limiting holes 22. The second limiting portions 21 are positioned opposite to the first limiting portions 13, and the first limiting holes 14, the second limiting holes 22, and the through hole 52 of the component to be fixed are also positioned opposite each other.

[0021] The first damping component 1 and the second damping component 2 are made of rubber and have good damping effect; the bushing 3 is made of metal, is placed in the mounting hole 12 and is interference-fitted with the mounting hole 12, and the length of the bushing 3 is less than the depth of the mounting hole 12, which avoids the rubber damping component being excessively squeezed, and reserves a reasonable deformation space for the damping component to ensure that the rubber material always maintains good elastic recovery ability.

[0022] During assembly, the first damping component 1 and the second damping component 2 are located on both sides of the fixing surface of the component to be fixed 5, respectively. The hollow positioning post 11 of the first damping component 1 passes through the assembly hole 51 of the component to be fixed 5 and is inserted into the inner ring of the second damping component 2. The two are matched in size. The bushing 3 is inserted into the hollow positioning post 11. The bushing 3 and the hollow positioning post 11 are interference-fitted and will not fall out of the hollow positioning post 11.

[0023] Adjust the positions of the first damper 1 and the second damper 2 so that the first limiting hole 14, the second limiting hole 22, and the through hole 52 of the component to be fixed 5 are aligned. This allows the rivet 4 to pass sequentially through the limiting hole 14 of the first damper 1, the through hole 52 of the component to be fixed 5, and the limiting hole 22 of the second damper 2, and then lock them in place. The rivet 4 is a blind rivet; after fixing, the first damper 1 and the second damper 2 will not fall off the component to be fixed 5, facilitating the installation of the damping components before the equipment leaves the factory. This avoids missing parts of the damping components and reduces the installation difficulty for users.

[0024] When installing the mounting bracket, place the mounting bracket 6 (only an example in the figure) on one side of the first damping component 1. The bolt 7 passes through the first washer 8, the mounting hole of the mounting bracket 6, the bushing 3, the second washer 9 and the nut 10 in sequence. Tighten the bolt 7 by rotating the nut 10, thereby assembling the mounting bracket 6 and the component 5 to be fixed together. The first damping component 1 and the second damping component 2 can reduce the vibration between the component 5 to be fixed and the mounting bracket 6.

[0025] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
