Description

Technical Field

[0001] This utility model relates to the field of three-way shock absorber technology, specifically to a metal and rubber combined three-way shock absorber. Background Technology

[0002] Traditional shock absorbers, as key components for vibration isolation in mechanical equipment, are widely used in industrial equipment, transportation, and precision instruments. Among existing technologies, metal spring shock absorbers and rubber shock absorbers are the two most common types. Traditional three-way shock absorbers often employ a structure with multiple springs connected in parallel and hydraulic damping to achieve foundation vibration isolation.

[0003] In existing technologies, multi-directional vibration damping designs generally employ multiple independent damping units to control vibrations in different directions. While this can improve the vertical vibration isolation effect, the overall size is large and it is difficult to coordinate the stiffness in each direction. At the same time, the horizontal stiffness is insufficient and there is a lack of an effective angular displacement constraint mechanism, which affects the damping effect. Therefore, a metal and rubber combined three-directional vibration damper is provided. Utility Model Content

[0004] The purpose of this invention is to provide a metal and rubber combined three-way shock absorber to solve the problems of large overall size and difficulty in coordinating stiffness in all directions, as well as insufficient horizontal stiffness and lack of effective angular displacement restraint mechanism, which affect the shock absorption effect.

[0011] Preferably, the rubber constraint assembly includes an arc-shaped connecting seat disposed at the bottom of the slider, the outer side of the arc-shaped connecting seat is covered with an arc-shaped rubber block, and the bottom of the mounting groove is configured as an arc-shaped surface adapted to the arc-shaped rubber block and fixedly connected to the arc-shaped rubber block.

[0012] Preferably, the elastic vibration isolation module, which is arranged along the Y-axis, is disposed on the base and located outside the mounting groove, and is connected to the connecting component;

[0013] Elastic vibration isolation modules arranged along the X-axis and Z-axis are respectively located between the four side walls of the connecting block and the inner wall of the mounting groove.

[0014] Preferably, the elastic vibration isolation module is composed of a metal spring assembly and a rubber body, wherein the rubber body covers the outer periphery of the metal spring assembly and fills its spring gaps.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This utility model is a metal and rubber combined three-way shock absorber. Through the composite structure of metal spring group and rubber body, the stiffness is coordinated, avoiding the problem of poor shock absorption effect caused by inconsistent stiffness in each direction.

[0016] This shock absorber, through its reasonable structural design, has a relatively small overall size, making it easy to install and use, and is especially suitable for occasions with limited space.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3 This utility model provides a technical solution: a metal and rubber combined three-way shock absorber, characterized in that it includes a base 1, which is made of cast steel, and has a mounting groove 11 on the base 1. The mounting groove 11 is a square groove with an arc-shaped concave bottom. Four sets of rectangular recesses are symmetrically opened on the four inner walls of the mounting groove 11 for fixing elastic vibration isolation modules 3 in the X and Z axes. A connecting component 2 is located above the base 1, and has a connecting block 21 extending into the mounting groove 11 at its bottom. The connecting component 2 is made of aluminum alloy, and a square connecting block 21 is welded to its bottom. The connecting block 21 is inserted into the mounting groove 11 of the base 1, and a gap is set between the connecting block 21 and the mounting groove 11. The shock absorber has three sets of elastic vibration isolation modules 3, distributed along the X, Y, and Z orthogonal directions, and all located between the base 1 and the connecting component 2. A constraint mechanism 4 is located between the bottom of the connecting block 21 and the bottom of the mounting groove 11. The elastic vibration isolation modules 3 coordinate the stiffness, preventing poor damping performance due to inconsistent stiffness in different directions. Through its reasonable structural design, the shock absorber has a relatively small overall size, making it easy to install and use, especially suitable for situations with limited space. The constraint mechanism 4 effectively limits the angular displacement of the connecting component 2, improving the stability of the shock absorber and preventing a decrease in damping performance due to excessive angular displacement.

[0024] Specifically, the constraint mechanism 4 includes a groove 41 located at the bottom of the connecting block 21. The bottom of the groove 41 is connected to a slider 43 via a spring 42. The stiffness coefficient of the spring 42 is 500-800 N / mm. A damper 44 is provided between the bottom of the groove 41 and the slider 43. The damper 44 is a hydraulic damper. A rubber constraint assembly is provided between the end of the slider 43 and the bottom of the mounting groove 11. The rubber constraint assembly includes an arc-shaped connecting seat 45 located at the bottom of the slider 43. The arc-shaped connecting seat 45 is welded to the bottom of the slider 43. An arc-shaped rubber block 46 is covered on the outside of the arc-shaped connecting seat 45. The bottom of the mounting groove 11 is set as an arc-shaped surface that matches the arc-shaped rubber block 46 and is fixedly connected to the arc-shaped rubber block 46. The arc-shaped rubber block 46 is made of neoprene rubber with a Shore hardness of 60-70. It is vulcanized and bonded to the outside of the arc-shaped connecting seat 45 and tightly fitted to the arc-shaped bottom of the mounting groove 11 to form a sliding limit structure.

[0025] Specifically, the elastic vibration isolation module 3 is composed of a metal spring group 31 and a rubber body 32. Each metal spring group 31 has three metal springs. The rubber body 32 is made of nitrile rubber and covers the outer periphery of the metal spring group 31 and fills the spring gaps. The elastic vibration isolation module 3 arranged along the Y-axis is set on the base 1 and located outside the mounting groove 11 and connected to the connecting component 2. There are four groups of elastic vibration isolation modules 3 arranged along the Y-axis, which are evenly distributed on the outside of the mounting groove 11. The elastic vibration isolation modules 3 arranged along the X-axis and Z-axis are respectively set between the four side walls of the connecting block 21 and the inner wall of the mounting groove 11. There are two groups of elastic vibration isolation modules 3 arranged along the X-axis and Z-axis, which are set on the opposite side walls of the connecting block 21 and in the recesses between the connecting block 21 and the inner wall of the mounting groove 11. The axis of the spring group is perpendicular to the corresponding side wall. The rubber body 32 is pre-compressed by 5%-8% and then vulcanized to ensure that the spring and rubber deform together during lateral vibration.

[0026] Working principle: During operation, when the connecting component 2 is subjected to impact and pressure during vertical vibration, the spring group 31 of the Y-axis elastic module is compressed, and the rubber body 32 provides damping and limits the lateral deformation of the spring; the slider 43 of the constraint mechanism 4 moves downward, and the arc-shaped rubber block 46 dissipates energy through friction with the arc-shaped surface of the mounting groove. During horizontal vibration, the connecting block 21 pushes the corresponding elastic module laterally, the spring group 31 deforms laterally, and the rubber body 32 absorbs energy through shearing action; the damper 44 of the constraint mechanism 4 suppresses the swing amplitude of the slider 43 and prevents overload.
