Description

Integrated shock-absorbing disc spring Technical Field

[0001] This utility model relates to the field of shock-absorbing disc spring technology, and in particular to an integrated shock-absorbing disc spring. Background Technology

[0002] In modern industrial equipment and transportation, disc springs are widely used in vibration damping systems due to their advantages such as high load-bearing capacity, small space occupation, and combinability. However, traditional disc spring assemblies often suffer from uneven stress on the springs due to a lack of effective constraint on axial displacement during actual operation, leading to premature fatigue failure in certain areas. Furthermore, under high-frequency vibration conditions, the disc springs themselves have insufficient damping characteristics, making it difficult to quickly attenuate vibration energy, affecting the operational stability and service life of the equipment. In addition, existing disc spring structures are prone to over-compression or uncontrolled rebound under extreme impacts due to the lack of a reliable rigid restraint structure, which not only reduces vibration damping performance but may also pose safety hazards. This new integrated vibration damping disc spring effectively limits axial displacement, efficiently absorbs high-frequency vibrations, and enhances structural stability to meet the vibration damping requirements under complex operating conditions. Summary of the Invention

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an integrated shock-absorbing disc spring. This solves the problem that the disc spring itself has insufficient damping characteristics under high-frequency vibration conditions, making it difficult to quickly attenuate vibration energy. Furthermore, through a rigid limiting structure, it can prevent the disc spring from rebounding and becoming uncontrollable.

[0004] This utility model also provides an integrated shock-absorbing disc spring, comprising: an upper support and a lower support, both of which are internally threaded with guide posts. A disc spring assembly is disposed inside each guide post, and a positioning assembly is disposed outside the guide post. The positioning assembly includes two buffer blocks, which are sleeved on the outside of the guide post and fixedly connected by a column. An annular block is fixedly connected inside the column. A crossbar is fixedly connected inside the upper support, and a limiting block is fixedly connected outside the crossbar. A pull rod is fixedly connected outside the limiting block, with one end of the pull rod away from the limiting block fixedly connected to the lower bottom wall of the upper support. The buffer blocks, column, and annular block work together to limit axial displacement by sleeved on the outside of the guide post. Simultaneously, the buffer blocks can further absorb high-frequency vibrations, and a rigid connection frame can be formed between the crossbar, limiting block, and pull rod, thereby enhancing the overall structural stability and preventing excessive compression or uncontrolled rebound of the disc spring assembly.

[0005] According to the integrated shock-absorbing disc spring of this utility model, the disc spring assembly is composed of two disc spring plates, and there are multiple disc spring assemblies symmetrically distributed on the outside of the guide post. The disc spring assembly composed of two disc spring plates, through symmetrical distribution, can evenly distribute the impact load borne by the guide post, absorb vibration energy by utilizing the axial elastic deformation of the disc spring, and at the same time avoid local stress concentration.

[0006] According to the integrated shock-absorbing disc spring of this utility model, the two buffer blocks are fixedly connected at their close ends, and the cross-section of the two buffer blocks is a bucket-shaped structure. The two buffer blocks form an integral structure through fixed connection, which can respond to impact loads synchronously, avoid the problem of uneven wear caused by uneven force on one side, and significantly improve lateral stability.

[0007] According to the integrated shock-absorbing disc spring of this utility model, the top end of the column penetrates through the upper support and extends into the interior, and the top end of the column is engaged with the limiting block 9 through a groove. The column and the limiting block form a connection structure, which can effectively suppress the lateral sway of the guide column.

[0008] According to the integrated shock-absorbing disc spring of this utility model, there are multiple columns symmetrically distributed around the central axis of the annular block, and all columns are circular tube structures. This forms a circumferentially distributed force transmission path, allowing the impact load to be evenly distributed throughout the entire disc spring assembly, avoiding stress concentration at a single point.

[0009] According to the integrated shock-absorbing disc spring of this utility model, the tie rods are symmetrically distributed on both sides of the limiting block, and the tie rods are arranged along the inclined direction. The tie rods on both sides cooperate to bear the force through the inclined angle, effectively dispersing the lateral impact load and suppressing the phenomenon of stress concentration on one side.

[0010] According to the integrated shock-absorbing disc spring of this utility model, the upper and lower supports have hollow interiors. The upper and lower supports have identical structures and work together. The hollow cavity serves as a secondary buffer space; when the disc spring assembly is compressed, some energy is conducted through the support walls to the hollow area, effectively reducing peak impact force.

[0011] According to the integrated shock-absorbing disc spring of this utility model, both the upper and lower ends of the guide column are threadedly connected to locking blocks, and the inner sides of the upper and lower supports abut against the locking blocks. The threaded locking blocks can finely adjust the preload of the guide column.

[0012] Beneficial effects: Compared with existing technologies, this new integrated shock-absorbing disc spring consists of a buffer block, a column, and an annular block. By fitting around the outside of the guide column, it restricts axial displacement. At the same time, the buffer block can further absorb high-frequency vibrations, and the crossbar, limit block, and pull rod can form a rigid connection frame, thereby enhancing the overall structural stability and preventing the disc spring assembly from being over-compressed or losing control of its rebound.

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Referring to Figures 1-4, the integrated shock-absorbing disc spring of this utility model embodiment includes: an upper support 1 and a lower support 2. Both the upper support 1 and the lower support 2 are threadedly connected to guide posts 3. Disc spring assemblies 4 are arranged inside the guide posts 3. Disc spring assemblies 4 are composed of two disc spring plates. There are multiple disc spring assemblies 4 and they are symmetrically distributed outside the guide posts 3. A positioning component is arranged outside the guide posts 3. The positioning component includes two buffer blocks 5. The two buffer blocks 5 are sleeved on the outside of the guide posts 3. The two buffer blocks 5 are fixedly connected by a column body 6. An annular block 7 is fixedly connected inside the column body 6. A crossbar 8 is fixedly connected inside the upper support 1. A limit block 9 is fixedly connected outside the crossbar 8. A pull rod 10 is fixedly connected outside the limit block 9. The end of the pull rod 10 away from the limit block 9 is fixedly connected to the lower bottom wall of the upper support 1. The pull rods 10 are symmetrically distributed on both sides of the limit block 9 and are arranged in an inclined direction.

[0022] Specifically, the disc spring assembly 4 achieves nonlinear stiffness characteristics through a double-plate combination design, providing gentle buffering in the early stages of compression and enhancing support under heavy loads. It can effectively absorb vertical impact energy. The threaded connection of the guide column 3, upper support 1 and lower support 2 ensures that the load is evenly transmitted to the symmetrically distributed multiple disc spring assemblies 4, improving the stability of the structure. The inclined tie rod 10 and the limiting block 9 form a triangular stabilizing structure, which decomposes the lateral force into axial components and transmits them to the upper support 1 and lower support 2, thereby preventing lateral displacement of the structure.

[0023] Two buffer blocks 5 are fixedly connected at their close ends, and the cross-section of the two buffer blocks 5 is a bucket structure. The top of the column 6 passes through the upper support 1 and extends into the interior. The top of the column 6 is engaged with the limiting block 9 through a groove. There are multiple columns 6 and they are symmetrically distributed around the central axis of the annular block 7. All columns 6 are circular tube structures.

[0024] Specifically, the buffer block 5 of the bucket body section generates radial expansion force when under pressure, while the axisymmetric distribution of the cylindrical tube 6 forms a ring damping array, which reduces the local stress peak by uniformly distributing the load, thereby preventing the disc spring assembly 4 from overload failure.

[0025] The upper support 1 and the lower support 2 have hollow interiors. The upper support 1 and the lower support 2 have the same structure and are used together. The upper and lower ends of the guide post 3 are threaded with locking blocks 11. The inner sides of the upper support 1 and the lower support 2 are in contact with the locking blocks 11.

[0026] Specifically, the hollow structure of the upper support 1 and the lower support 2 achieves weight reduction, and the inner side of the upper support 1 and the lower support 2 contacts the plane of the locking block 11 to form a bidirectional limit, which can restrict the axial movement of the guide column 3.

[0027] Working principle: First, the impact force is transmitted to the guide column 3 through the lower support 2. The threaded guide column 3 evenly distributes the load to multiple symmetrically distributed disc spring groups 4. Primary buffering is achieved through the nonlinear deformation of the disc springs. Together with the inclined tie rod 10 and the limiting block 9, a triangular stabilizing structure is formed, which can decompose the lateral force into an axial component and transmit it to the upper support 1 through the crossbar 8, thereby suppressing the lateral tilt of the structure. In addition, the buffer block 5 is linked through the column 6 and generates frictional damping when the guide column 3 reciprocates, forming a composite vibration absorption effect with the elastic damping of the disc spring group 4.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
