Description

Technical Field

[0001] This utility model relates to the field of buffer devices, and in particular to a buffer device for a spring-operated mechanism. Background Technology

[0002] Buffer devices are commonly used in automated production lines. When drive components move the actuators, they inevitably cause some impact on the equipment. This is especially true given the increasing production demands for capacity, which lead to faster and faster equipment operation. Increased operating speed leads to greater impact on the equipment, causing vibrations, reducing the lifespan of components, and exacerbating noise pollution in the workshop. Therefore, installing buffer devices on the equipment is essential to reduce the impact of its movement.

[0003] The inventors of this application have discovered the following problems in practical use: electronic devices may vibrate when releasing energy during use. If the vibration is too large, the electronic device may tip over, resulting in damage to the electrical components.

[0004] Currently, most electronic devices do not have a cushioning device installed on the base, and the electronic device will vibrate greatly when overcurrent protection is activated, and the internal power will be cut off instantly. This vibration will cause the electronic device to tip over.

[0005] Therefore, it is necessary to provide a buffer device for a spring-operated mechanism to solve the above-mentioned technical problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a buffer device for a spring operating mechanism, which addresses the above-mentioned deficiencies of the prior art.

[0007] To achieve the above objectives, the technical solution of this utility model is: a buffer device for a spring operating mechanism, characterized in that: it includes a main body and a base plate, a buffer mechanism is provided between the main body and the base plate, the buffer mechanism is provided with two longitudinal buffer structures, four transverse buffer structures are provided around the longitudinal buffer structures, the main body is fixedly connected to the longitudinal buffer structure through a support platform, and a connecting rod is provided on both sides of the support platform, the connecting rod is rotatably connected to the connecting rod two through a rotating shaft.

[0008] By adopting the above technical solution, this device forms a core shock-absorbing layer through a buffer mechanism between the main body and the base plate. Its double longitudinal buffer structure directly bears the vertical impact force from the supporting platform, effectively resisting the strong kinetic energy load when the spring operating mechanism operates, and avoiding deformation of the main structure caused by rigid transmission. At the same time, the four transverse buffer structures arranged around the longitudinal structure form a multi-directional protective net, significantly suppressing lateral swaying of the equipment.

[0009] Furthermore, a hydraulic buffer is provided below the support platform, and a first buffer plate is provided on one side of the rotating shaft.

[0010] By adopting the above technical solution, a hydraulic buffer is added below the support platform. Its viscous damping characteristics can efficiently absorb high-frequency instantaneous impacts, make up for the short response speed of mechanical buffers under extreme working conditions, and greatly extend the fatigue life of the equipment. At the same time, the first buffer plate on the rotating shaft side provides elastic limit when the connecting rod rotates.

[0011] Furthermore, the lateral buffer structure includes a second buffer sheet, a connecting piece is provided on one side of the second buffer sheet, and a spring is provided on one side of the connecting piece.

[0012] By adopting the above technical solution, the lateral buffer structure uses the second buffer plate as the impact contact surface, and initially absorbs energy through the compression deformation of the rubber material; the connecting plate transmits the impact force to the spring, and utilizes its linear expansion and contraction characteristics to transform the sudden impact into periodic, slow-release vibration. At the same time, the fixed connection between the spring and the movable plate forms a rigid traction mechanism, ensuring that the energy transfer path is controllable.

[0013] In a further configuration, the connecting piece is elastically connected to a rotating rod via a spring, the spring is fixedly connected to the movable plate, and a fixing bracket is provided on one side of the spring for fixing purposes.

[0014] By adopting the above technical solution, the connecting plate is elastically connected to the rotating rod via a spring, so that the impact force is flexibly transmitted through the spring and converted into the rotational torque of the rotating rod, reducing the risk of instantaneous overload; the movable plate is fixed to the spring, which constrains the vibration direction and maintains a controllable buffer trajectory. At the same time, the fixed frame provides axial positioning for the rotating rod, and the threaded connection of the limit ring enables precise stroke control.

[0015] Furthermore, the fixing frame is threadedly connected to a rotating rod via a limiting ring, and the rotation of the rotating rod can control the distance between the first buffer plate and the second buffer plate.

[0016] By adopting the above technical solution, the fixed frame forms a precision guiding mechanism through the threaded connection between the limiting ring and the rotating rod. The depth of the limiting ring screwing in can finely adjust the effective working length of the rotating rod. At the same time, the rotation of the rotating rod directly links the movable plate, driving it to move laterally along the fixed frame, synchronously changing the initial compression of the spring.

[0017] In a further configuration, the rotating rod is rotatably connected to a rotating handle, which is threadedly connected to the rotating rod, causing the movable plate to move the spring left and right.

[0018] By adopting the above technical solution, the linkage design between the handle and the rod provides tool-less adjustment capability; the rod can be rotated manually by turning the handle. Simultaneously, the threaded drive of the rod forces the movable plate to shift horizontally, causing the traction spring to undergo directional expansion and contraction deformation, achieving linear adjustment of the buffer preload.

[0019] Furthermore, pulleys are provided on both sides of the base plate, and the pulleys move through the slide rails to drive the main body to move.

[0020] By adopting the above technical solution, the pulleys on both sides of the base plate convert the sliding friction of the main body into rolling friction. The guide rail significantly reduces the movement resistance and avoids the additional vibration caused by the jamming of the traditional base. At the same time, the pulley-rail mechanism provides a precise linear movement path for the main body.

[0021] Furthermore, both the first and second buffer sheets are made of rubber.

[0022] By adopting the above technical solution, the rubber material of the first buffer sheet and the second buffer sheet has high damping characteristics. Its molecular chain structure generates intramolecular friction when compressed and deformed, which efficiently converts the impact kinetic energy into heat energy dissipation. At the same time, the elastic-plastic deformation of the rubber can adapt to vibrations of different frequencies, avoiding high-frequency vibration of metal buffer components. Its insulation properties further block the risk of current conduction.

[0023] Compared with related technologies, the buffer device for spring-operated mechanisms provided by this utility model has the following beneficial effects:

[0024] This device forms a core shock-absorbing layer through a buffer mechanism between the main body and the base plate. Its longitudinal buffer structure directly bears vertical impacts, while the transverse buffer structure suppresses lateral displacement, reducing the risk of equipment overturning through multi-directional coordination. Simultaneously, connecting rods one and two of the support platform are hinged via a rotating shaft to convert impact energy. A hydraulic buffer further absorbs high-frequency instantaneous loads, forming a composite buffer mechanism. The second buffer plate of the transverse buffer structure transmits the impact to the spring through a connecting plate. The spring's expansion and contraction dissipates energy. The movable plate and fixed frame constrain the spring's movement trajectory. The rotating rod adjusts the spring's pre-compression via a limit ring. Rotating the handle drives the rotating rod to rotate, causing the movable plate to shift and dynamically adjust the distance between the first and second buffer plates to adapt to different impact intensities under different working conditions.

[0030] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings show typical embodiments of this utility model.

[0031] In this embodiment:

[0032] like Figure 1 As shown, this utility model discloses a buffer device for a spring-operated mechanism, comprising a main body 1 and a base plate 2. A buffer mechanism 3 is provided between the main body 1 and the base plate 2. The buffer mechanism 3 has two longitudinal buffer structures 4, and four transverse buffer structures 5 are provided around the longitudinal buffer structures 4. The longitudinal buffer structures 4 are fixedly connected to the main body 1 through a support platform 6. Connecting rod 7 is provided on both sides of the support platform 6. Connecting rod 7 is rotatably connected to connecting rod 8 through a rotating shaft 10. This device forms a core shock-absorbing layer through the buffer mechanism 3 between the main body 1 and the base plate 2. Its double longitudinal buffer structures 4 directly bear the vertical impact force from the support platform 6, effectively resisting the strong kinetic energy load when the spring-operated mechanism is in operation, avoiding deformation of the main structure caused by rigid transmission. The connecting rod 7 and connecting rod 8 on both sides of the support platform 6 are hinged together through the rotating shaft 10, converting the impact energy into the rotational potential energy of the linkage mechanism, dispersing and weakening the vibration wave transmission path, and fundamentally reducing the risk of equipment overturning.

[0033] like Figure 2 As shown, a hydraulic buffer 9 is installed below the support platform 6, and a first buffer plate 11 is installed on one side of the rotating shaft 10. The hydraulic buffer 9 is added below the support platform 6. Its viscous damping characteristics can efficiently absorb high-frequency instantaneous impacts, such as the moment of opening and closing of the mechanism, to make up for the short response speed of mechanical buffer under extreme working conditions and greatly extend the fatigue life of the equipment. At the same time, the first buffer plate 11 on the side of the rotating shaft 10 provides elastic limit when the connecting rod rotates, which not only prevents the rotating shaft 10 from overtravel wear, but also dissipates the lateral torsional vibration energy through its own deformation, forming a vertical-torsional complementary protection system with the hydraulic buffer 9.

[0034] like Figure 3 As shown, the transverse buffer structure 5 includes a second buffer plate 52, a connecting plate 53 on one side of the second buffer plate 52, and a spring 54 on one side of the connecting plate 53. The transverse buffer structure 5 uses the second buffer plate 52 as the impact contact surface, and initially absorbs energy through the compression deformation of the rubber material. The connecting plate 53 transmits the impact force to the spring 54, and uses its linear expansion and contraction characteristics to convert the sudden impact into periodic damping vibration. At the same time, the fixed connection between the spring 54 and the movable plate 58 forms a rigid traction mechanism to ensure that the energy transfer path is controllable. The fixed frame 55 restricts the range of motion of the spring, avoids stress concentration due to displacement failure, and ensures the stability of the transverse buffer under multiple working conditions.

[0035] like Figure 3 As shown, the connecting piece 53 is elastically connected to the rotating rod 57 via a spring 54. The spring 54 is fixedly connected to the movable plate 58. A fixing bracket 55 is provided on one side of the spring 54 for fixing. The connecting piece 53 is elastically connected to the rotating rod 57 via the spring 54, so that the impact force is flexibly transmitted through the spring and converted into the rotational torque of the rotating rod 57, reducing the risk of instantaneous overload. The fixed connection between the movable plate 58 and the spring 54 constrains the vibration direction and maintains a controllable buffer trajectory. At the same time, the fixing bracket 55 provides axial positioning for the rotating rod 57, and the threaded connection of the limiting ring 51 enables precise stroke control. By rotating the rotating rod 57, the movable plate 58 is displaced, and the pre-compression of the spring 54 is precisely adjusted to dynamically adapt to different impact conditions.

[0036] like Figure 3 As shown, the fixed frame 55 is threadedly connected to the rotating rod 57 via a limiting ring 51. Rotation of the rotating rod 57 controls the distance between the first buffer plate 11 and the second buffer plate 52. The fixed frame 55, through the threaded connection between the limiting ring 51 and the rotating rod 57, forms a precision guiding mechanism. The screw depth of the limiting ring 51 can finely adjust the effective working length of the rotating rod 57. Simultaneously, the rotation of the rotating rod 57 directly links to the movable plate 58, driving it to move laterally along the fixed frame 55, synchronously changing the initial compression of the spring 54, thereby precisely controlling the distance between the first buffer plate 11 and the second buffer plate 52. This distance adjustment capability allows the device to adapt to longitudinal-lateral composite vibrations of different amplitudes, significantly improving operational compatibility.

[0037] like Figure 3As shown, a rotating handle 56 is rotatably connected to the rotating rod 57. The rotating handle 56 is threadedly connected to the rotating rod 57, causing the movable plate 58 to move the spring 54 left and right. The linkage design between the rotating handle 56 and the rotating rod 57 provides tool-less adjustment capability; the rotating rod 57 can be driven to rotate by manually rotating the handle. Simultaneously, the threaded transmission of the rotating rod 57 forces the movable plate 58 to shift horizontally, causing the traction spring 54 to undergo directional expansion and contraction deformation, achieving linear adjustment of the buffer preload. This mechanical adjustment mechanism can dynamically optimize buffer parameters without disassembling parts, greatly improving equipment maintenance efficiency and adaptability to operating conditions.

[0038] like Figure 4 As shown, pulleys 12 are provided on both sides of the base plate 2. The pulleys 12 move through the slide rail to drive the main body 1. The pulleys 12 on both sides of the base plate 2 convert the sliding friction of the main body 1 into rolling friction. The slide rail guide greatly reduces the movement resistance and avoids the additional vibration caused by the jamming of the traditional base. At the same time, the pulley-slide rail mechanism provides a precise linear movement path for the main body 1, ensuring that the longitudinal buffer structure 4 and the transverse buffer structure 5 are always in the optimal force direction, maximizing the energy absorption efficiency of the buffer mechanism and suppressing the risk of unexpected off-center loading from the source of movement.

[0039] like Figure 4 As shown, further configured, both the first buffer sheet 11 and the second buffer sheet 52 are made of rubber. The rubber material of the first buffer sheet 11 and the second buffer sheet 52 has high damping characteristics. Its molecular chain structure generates intramolecular friction during compression deformation, efficiently converting impact kinetic energy into heat energy dissipation. At the same time, the elastic-plastic deformation of rubber can adapt to vibrations of different frequencies, avoiding high-frequency vibrations of metal buffer components. Its insulation properties further block the risk of current conduction, providing double safety protection under the arc impact condition of the spring operating mechanism, improving the reliability and environmental adaptability of the device from the material essence. In implementation, when the spring operating mechanism is running, the vibration energy generated by the main body 1 is transmitted to the buffer mechanism 3 through the support platform 6. The longitudinal impact is first absorbed by the longitudinal buffer structure 4, while the hydraulic buffer 9 further attenuates the vertical vibration. Lateral impacts are buffered by four lateral buffer structures 5 arranged in a ring. The impact force drives the second buffer plate 52, which compresses the spring 54 through the connecting plate 53. The elastic deformation of the spring 54 converts the impact energy into elastic potential energy and dissipates it. The movable plate 58 is pulled by the spring 54 and can move along the fixed frame 55 to stabilize the structure. The vibration energy is simultaneously transmitted to the linkage mechanism. The rotating shaft 10 drives the first connecting rod 7 and the second connecting rod 8 to rotate relative to each other, and the elastic deformation of the first buffer plate 11 assists in buffering. If the buffer stroke needs to be adjusted, the handle 56 is turned to drive the rotating rod 57 to rotate, so that the limiting ring 51 on the fixed frame 55 drives the movable plate 58 to move, changing the pre-compression of the spring 54, thereby adjusting the distance between the first buffer plate 11 and the second buffer plate 52.

[0040] The advantages of this technical solution in practical applications include, but are not limited to, the following:

[0041] 1. The modular transverse buffer unit supports independent replacement, reducing maintenance costs. The guide structure of the fixed frame and movable plate prevents spring misalignment failure.

[0042] 2. The rotating rod and limit ring adjustment mechanism, together with the rotating handle, enables tool-free operation and allows for quick adjustment of the spring pre-compression.
