Description

VIBRATION ISOLATION MOUNT

More particularly, the present invention relates to a vibration damping mount, and more particularly, to a vibration damping mount capable of coping with various loads and easily fastened to various equipments, To prevent a component from being damaged or deformed even if a load is applied to the mount.

Generally, a vibration-damping mount is installed between a device and a floor when a vibrating device (e.g., an audio system, a compressor) or the like is supported in a place such as a floor, Thereby preventing vibration from being transmitted to the floor.

At the same time, it is used to block external vibrations (vibration suppression) in order to prevent the inherent function of the equipment from degrading due to the influence of external vibration when using equipment that is vulnerable to vibration such as precision measuring equipment or semiconductor manufacturing equipment. .

At this time, the vibration-damping mount is constructed by using a cushioning material having a property of absorbing vibration well. In order to effectively use the static displacement in various devices, a spring is often used as the cushioning material.

A general damping mount generally includes a coil shaped spring, an upper support member coupled to an upper end of the spring for generating vibration, a lower support member coupled to a lower end of the spring to contact the bottom, And an adjusting bolt for adjusting the horizontal position of the apparatus in which vibration is generated.

However, as described above, since the vibration mount having the structure of spring, bolt, and the like is fixedly installed for a long time, there is a need to replace parts due to corrosion.

It can also be replaced with appropriate parts (eg, springs, etc.) to accommodate various loads.

In addition, there is a need to securely fix the device mounted on the upper support member to the upper support member. Particularly, when a load exceeding the vibration absorption capability of the spring is generated, the component is damaged or deformed.

Looking at each configuration,

The lower body 10 ,

As shown in Figs. 1 and 2,

A through hole 111 is formed in the upper portion and a lower space portion 112 is formed in the inner portion to be in contact with a floor or a table on which the vibration mount is placed.

A lower housing 11 having the lower space portion 112 largely opened downward and a lower plug 12 having a lower coupling hole 121 penetrating the upper space and the lower space and closing the lower space portion 112.

3, the lower housing 11 is formed with an extension 113 protruding upward from the center, and the through hole 111 is formed at the upper center of the extension 113. As shown in FIG.

The lower plug 12 has upper and lower coupling holes 121 formed therein and an upper protrusion 122 protruded from the upper surface of the lower plug 12, (A) of the guide member (20).

At this time, the lower fastening hole 121 is engaged with a bolt to be fastened to various equipment such as a work table (see FIG. 3).

The 'falling section A' is a distance at which the guide member 20 moves up and down in the lower space part 112.

The lower housing 11 is formed with a lower installation hole 114 formed to pass through the lower space and the lower space 112 in the left and right directions. The lower installation hole 114 is provided with a set screw 115 ) Are combined.

Therefore, the set screw 115 firmly fixes the lower plug 12 to the lower housing 11.

Further, due to the structure of the lower plug 12 and the lower mounting hole 114, the present invention can quickly replace the parts.

In some cases, a step is formed along the inner periphery on the lower side of the lower space part 112, so that the lower end of the lower plug 12 is caught.

Therefore, the lower plug 12 can be more firmly coupled to the lower space portion 112.

A depression 117 may be formed on the upper surface of the extension 113 so that the lower end of the elastic spring 40 may be seated. In this case, the depression 117 may insert the elastic spring 40 So that it can be stably supported (see Fig. 3)

The guide member 20 ,

As shown in Figures 2 and 3,

A head portion 21 that is vertically inserted into the lower space portion 112 of the lower body 10 and a head portion 21 which protrudes upward from the head portion 21 and passes through the through hole 111 of the lower body 10 And a spiral portion 22 which is exposed upward from the lower body 10.

At this time, the spiral portion 22 is screwed to the upper body 30.

A seating groove 23 is formed in a lower surface of the head portion 21 of the guide member 20 to allow the upper end of the raised portion 122 of the lower plug 12 to enter.

At this time, it is preferable that the head portion 21 and the seating groove 23 have a shape corresponding to each other.

More specifically,

As shown in Figure 4,

Even if the guide member 20 descends in the lower space portion 112 at a load not exceeding the vibration absorbing capacity of the elastic spring 40, 12).

However, as shown in FIG. 5,

The head portion 21 of the guide member 20 is further lowered to be engaged with the protruding portion 122 of the lower plug 12, The base portion 122 is seated on the head portion 21.

At this time, since the head portion 21 and the protruding portion 122 have a corresponding shape, the guide member 20 is fixed to the lower plug 12 so that it does not vibrate even when a load is applied.

Also, the upper body 30, which is screwed with the guide member 20, does not vibrate.

In the absence of the guide member 20 and the lower plug 12,

When a load exceeding the vibration absorbing capacity of the elastic spring 40 is generated, the upper body 30 is continuously vibrated and the upper body 30 and the lower body 10 are collided with each other to break and deform, The elastic spring 40 may also be deformed.

In the present invention, since the lower plug 12, the guide member 20 and the upper body 30 are firmly fixed to each other, when a load exceeding the vibration absorbing capacity of the elastic spring 40 is generated, It does not vibrate, so there is an effect of preventing the component from being damaged or deformed.

A spacer ring 24 is coupled to the lower portion of the spiral portion 22 of the guide member 20 along the periphery of the spiral portion 22.

Therefore, the height of the upper body 30 coupled to the guide member 20 can be adjusted by adjusting the thickness and the number of the space rings 24.

The upper body 30 ,

As shown in Figs. 1 to 3,

A device for generating vibration is placed on the upper portion thereof,

Is coupled to the spiral part (22) of the guide member (20) and ascends and descends together with the guide member (20).

The upper body 30 includes an upper housing 31 having an upper hollow portion 311 which is greatly opened downward and into which the extended portion 113 of the lower housing 11 enters, An upper plug 32 having an upper fastening hole 321 to which the spiral portion 22 of the guide member 20 is fastened and a cushioning member 32 interposed between the elastic spring 40 and the upper plug 32. [ And a member (33).

As described above, the spiral portion 22 of the guide member 20 is coupled to the lower portion of the upper fastening hole 321 of the upper plug 32, and the upper fastening hole 321 has a space The bolt is coupled to the space, and it is possible to tighten the bolt with a device that generates vibration (refer to FIG. 3).

The upper housing 31 is provided with an upper installation hole 312 formed to pass through the upper space and the upper space 311 in the left and right direction. The upper installation hole 312 is coupled with the set screw 313 .

Therefore, the set screw 313 firmly fixes the upper plug 32 to the upper housing 31.

Further, since the upper plug 32 and the upper mounting hole 312 are easily separated from each other, the present invention enables rapid replacement of parts.

On the other hand, a step may be formed along the inner periphery on the upper side of the upper hollow portion 311, so that the upper end of the upper plug 32 is caught.

Therefore, the upper plug 32 can be more firmly coupled to the upper hollow portion 311.

As shown in FIG. 4, the upper housing 31 is lowered together with the upper plug 32 coupled to the guide member 20 as it descends.

The lower end of the upper housing 31 is lowered toward the upper surface 116 of the lower housing 11. At this time, the gap B between the lower end of the upper housing 31 and the upper surface 116 of the lower housing 11 Is preferably longer than the descending section A of the guide member 20 (see FIG. 3).

This is to prevent the upper housing 31 and the lower housing 11 from directly contacting each other and being damaged during the lifting operation of the upper housing 31. [

The buffer member 33 is made of an elastic body such as rubber. The buffer member 33 attenuates the load applied to the elastic spring 40.

The resilient spring 40 ,

As shown in Figures 2 and 3,

The upper body 10 and the guide member 20, which have been lowered due to the load, are returned to the initial positions by being absorbed by the guide member 20.

Here, 'initial position' means a position where the upper body 10 and the guide member 20 are raised when there is no load applied to the upper body 10 and the guide member 20.

The elastic spring 40 is preferably a compressed coil spring made of metal.

Generally, the resonance frequency (resonance frequency) of the rubber material varies depending on the product. However, since it is more than 100HZ, it is suitable for local vibration shutdown, but it is not suitable for the low frequency (100HZ).

However, since the present invention performs vibration damping with a compression coil spring, it is possible to perform vibration damping at 100 HZ or less, thereby providing an excellent vibration damping performance as compared with a rubber material.

The present invention, due to its simple structure,

It has the effect of lowering the manufacturing and maintenance cost compared with the excellent vibration damping performance, and at the same time, it is possible to have a small structure, and there is an additional effect that it can be easily applied to various devices such as audio equipment.

Further, since the elastic spring 40 can be easily replaced only by a simple operation of separating the upper plug 32, it is possible to cope with various loads such as precision equipment vibration of 20KG or less.

In other words, there are effects that can be used in various environmental conditions.

In the meantime, according to the present invention, bolts are coupled to the upper fastening holes 321, so that the upper plug 32 and the plate P can be fastened.
