Description

Technical Field

[0001] This utility model belongs to the field of vibration reduction technology for mechanical equipment, and specifically relates to a vibration damping pad. Background Technology

[0002] In industrial production and equipment installation, mechanical equipment generates vibrations and impacts during operation. If these vibrations are not isolated, they not only generate noise and affect the working environment, but also lead to fatigue damage to the equipment itself and its connecting components. To alleviate this problem, vibration-damping pads are usually installed at the bottom of the equipment base. Existing vibration-damping pads mostly use pure rubber pads. While pure rubber pads have a certain vibration-damping effect, they are prone to irregular deformation under complex loads (such as routine lateral dragging of equipment), posing a risk of the pad breaking or tearing, thus affecting its vibration-damping effect and structural stability. Therefore, there is an urgent need for vibration-damping pads that can effectively constrain the deformation direction of the rubber pad, thereby improving the overall structural stability and connection strength, and extending its service life. Utility Model Content

[0003] This invention addresses the shortcomings of the prior art by providing a shock-absorbing pad foot that can effectively constrain the deformation direction of the rubber pad block, thereby improving the overall structural stability and connection strength, and extending its service life.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A shock-absorbing pad includes an upper cover plate, a rubber pad block, and a lower cover plate. The rubber pad block is disposed in the receiving space formed between the upper cover plate and the lower cover plate. Multiple shoulder limiting bolts are evenly connected to the outer periphery of the upper cover plate and the lower cover plate. The shoulder limiting bolts pass through the lower guide hole provided on the lower cover plate and are threaded with a first nut to achieve locking. The upper cover plate is provided with an upper guide hole that is slidably connected to the bare shaft shoulder section of the shoulder limiting bolt.

[0005] Preferably, both the upper cover plate and the lower cover plate are disc-shaped structures with a central groove.

[0006] Preferably, both the upper cover plate and the lower cover plate have a hollow structure.

[0007] Preferably, the number of shoulder limiting bolts is three or four.

[0008] Preferably, the top of the cover is provided with a fixing screw for connection with mechanical equipment.

[0009] Preferably, the fixing screw is provided with a second nut, an elastic washer, and a flat washer.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, through the constraint of multiple shoulder limiting bolts, ensures that the upper cover plate can only move vertically when subjected to vibration, forcing the rubber pad to undergo vertical compression and rebound deformation, thus avoiding lateral deformation. Furthermore, the overall structural stability and connection strength of the upper and lower cover plates are high, effectively preventing the rubber pad from tearing or breaking, and extending its service life. The top of the upper cover is equipped with a fixing screw, facilitating installation with mechanical equipment and making it convenient to use. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] In the description of this utility model, it should be understood that the terms "middle", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or 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. Therefore, they should not be construed as limitations on this utility model.

[0015] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection; a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0016] like Figures 1 to 3 As shown, a shock-absorbing pad includes an upper cover plate 1, a rubber pad 2, and a lower cover plate 3. The upper and lower cover plates are both metal parts, such as steel or aluminum alloy. Both the upper and lower cover plates are disc-shaped structures with a groove in the center, and their surfaces are perforated to reduce weight and manufacturing costs. The rubber pad is a highly elastic rubber body and is housed in the receiving space formed between the upper and lower cover plates. Multiple shoulder limiting bolts 4 are evenly connected to the outer periphery of the upper and lower cover plates. The shoulder limiting bolts pass through the lower guide hole 301 on the lower cover plate and are threadedly connected to a first nut 5 for locking. The upper cover plate has an upper guide hole 101 that slides through the smooth shoulder section 401 of the shoulder limiting bolt. The shoulder limiting bolt, also called a stop bolt or locking bolt, consists of a smooth shoulder section and a threaded connection section. The threaded connection section is threadedly connected to the first nut, allowing it to be locked to the lower cover plate. The upper guide hole has a clearance fit with the smooth shoulder section, allowing the upper cover plate to slide freely vertically along the smooth shoulder section, but its horizontal movement and rotation are constrained. The number of shoulder limiting bolts is three or four; in this embodiment, four shoulder limiting bolts are used to ensure uniform force distribution and structural stability.

[0017] To facilitate the assembly and connection of the shock-absorbing pads of this utility model with the bottom of the mechanical equipment, a fixing screw 6 for connection with the mechanical equipment is provided on the top of the upper cover, such as... Figure 4 As shown, during use, the fixing screw can be passed through the mechanical equipment support leg 10 or other support components with mounting holes. The fixing screw is equipped with a second nut 7, an elastic washer 8, and a flat washer 9 to ensure the stability of the connection structure between the upper cover plate and the mechanical equipment.

[0018] In use, this utility model is installed at the bottom of the mechanical equipment to be damped, i.e., the fixing screw 6 on the upper cover plate 1 passes through the mounting hole on the support leg 10 of the mechanical equipment (this embodiment takes this as an example). The flat washer 9 and the elastic washer 8 are then sequentially fitted, and the second locking nut 7 is tightened to complete the equipment installation. The weight of the mechanical equipment is applied to the damping pad of this utility model, and the pressure is transmitted through the upper cover plate 1 to the elastic rubber pad 2, causing it to undergo a certain vertical compression. Under pressure, the upper cover plate slides downward along the shoulder section 401 of the shoulder limiting bolt 4. During routine maintenance, the rubber pad can be disassembled and replaced by removing multiple shoulder limiting bolts, making maintenance convenient.

[0019] When the mechanical equipment vibrates during operation, the vibration energy is transmitted to the upper cover plate 1 through the fixing screw 6. Due to the large weight of the mechanical equipment, the upper cover plate 1 will generate slight reciprocating motion in the vertical direction, compressing or releasing the elastic rubber pad 2 below it. The elastic rubber pad 2, through its own elastic deformation, converts the mechanical vibration energy into internal energy and dissipates it (such as heat energy), thereby reducing vibration transmission and achieving shock absorption and buffering. Constrained by multiple shoulder limiting bolts 4, the upper cover plate 1 can only slide vertically, and the deformation of the rubber pad 2 is limited to the vertical direction. At the same time, the connection structure between the upper cover plate 1 and the lower cover plate 3 also ensures its overall stability and connection strength. During the daily dragging and moving of the mechanical equipment, since the upper cover plate 1 and the lower cover plate 3 cover the rubber pad 2 inside, the rubber pad can be effectively prevented from being torn or broken. The specific composition, hardness, and pre-compression of the rubber pad need to be determined according to the actual load and vibration frequency, etc., and are not within the protection scope of this utility model.

[0020] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all changes falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model.
