Description

{VIBRATION PREVENTING DEVICE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust-proofing field, and more particularly, to a dust-proofing assembly and a dust-proofing device including the same.

Generally, manufacturing facilities are supported by members for dust prevention (vibration prevention) in order to increase the reliability of the process as well as the stability of each facility because various facilities are accommodated. These anti-vibration members are usually in the form of a mount, a pad or the like in which a rubber, a rubber and a spring are mixed, and are interposed between the respective equipments and the ground (or bottom surface).

Conventional conventional anti-vibration members and devices are interposed individually at several places of the target facility or interposed as one anti-vibration rubber pad type. The conventional method has a problem that both are not easy to install. Basically, since the manufacturing facilities are heavy, the wheels or the leg members are attached to the lower surface, and the anti-vibration mount members are attached to the portions after removing the wheel or the legs attached to the wheels or the leg members. Not only does this process require a relatively long working time, but also precise construction is not easy. In addition, the conventional general vibration damping elements are not easy to install as described above, while the vibration damping elements are installed alone such as individual mount elements, and the vibration damping efficiency is not so high. In addition, since the conventional single pad type anti-vibration member receives all the loads applied to one pad, the life of the material is shortened, which results in a sudden drop in functionality after a certain period of use.

As the precision of the manufactured products is increasing day by day, the manufacturing process also requires high precision. Otherwise, the actual utilization rate of the equipment is inevitably lowered.

Therefore, there is a demand for a first embodiment of a dustproof device that is easy to install and can perform precise vibration and shock control.

For example, the multilayer pad portion 21 absorbs vibration in the longitudinal direction (Z-axis direction), and one or more rubber mount elements 22 can absorb vibration in the front, rear, left and right (X- and Y-axis directions) .

More specifically, in the multilayer pad portion 21 included in the dustproof assemblies 20a, 20b, 20c, and 20d according to the preferred embodiment of the present invention, two or more rubber pads 212 are stacked. In this multilayer pad portion 21, an intermediate plate 214 is disposed between the rubber pads 212. A lower plate 211 is disposed under the multilayer pad portion 21. [ An upper plate 213 is disposed on an upper portion of the uppermost rubber pad 212 and a rubber mount element 22 described later is disposed on the upper plate 213. The rubber pads 212 may have a plurality of grooves 2121 each having a concavo-convex shape in its bottom surface.

Preferably, the bottom plate 211 includes an outwardly extending fixing portion 24, and the fixing portion 24 may be fixed to the bottom (surface) of the corresponding vibration preventing assembly using a fixture such as a screw or a bolt. And has a groove 241. The fixing grooves 241 may be formed in various shapes in which fasteners such as screws or bolts are inserted to fix the fixing portions 24. As in the illustrated example, the fixture 24 may be more than one for each anti-vibration assembly, but preferably may be disposed on both sides or more for balance.

As described above, one or more rubber mount elements 22 are disposed on the top plate 213 of the multilayer pad portion 21. The number of rubber mount elements 22 to be disposed may be one, two, or four, but is not limited thereto.

Lt; RTI ID = 0.0 > 22 < / RTI > Figures 3c and 3d also show another example of an arrangement in which two or three rubber mount elements 22 are arranged. Figures 4A and 4B show an example in which four rubber mount elements 22 are arranged.

2a to 2c of the examples in which the two are disposed are examples in which the rubber mount elements 22 are arranged in a diagonal direction on a top plate 213 of a similar shape. In such a case, the multilayer pad portion 21 can be used interchangeably in a configuration in which two rubber mount elements 22 are arranged in the multilayer pad portion 21 on which the four rubber mount elements 22 are disposed.

Figures 3c and 3d show the anti-vibration assembly that can be placed at the corner of the target facility. In this case, as shown in the drawing, the multilayer pad portion 21 is formed in the shape of a letter, and two (FIG. 3C) or three (FIG. 3D) can be arranged thereon.

Each of the above rubber mount elements 22 has a bowl shape arranged in a reverse direction, and air may be filled therein, but is not limited thereto. Each of these rubber mount elements 22 performs a vibration control operation, and controls or prevents vibration by absorbing vibration in the left-right direction as described above.

A cover portion (23) is arranged on the rubber mount element (22). The cover portion 23 may have a shape covering the upper portion of the multilayer pad portion 21 including the rubber mount element 22 as in the illustrated example, but is not limited thereto. The cover part 23 may be provided with a first coupling hole 121 for coupling with a target facility using a fastener (not shown) such as a screw or a bolt.

The vibration-proof assemblies 20a, 20b, 20c, and 20d may be disposed at appropriate positions to control the vibration while supporting the target equipment. The arrangement or arrangement of the dustproof assemblies 20a, 20b, 20c, and 20d may be variable depending on the target facility and the field conditions, but the arrangement in which the target facility can be stably supported will be selected.

Fig. 7 is a bottom view of the vibration isolation device according to the first embodiment of the present invention. Fig. Fig. 8 is a cross-sectional view taken along line A-A 'of the dustproof device shown in Fig. 5A. Fig. 9 is a view showing a base frame employed in the first embodiment of the dustproof device of the present invention. 10 is an exploded perspective view of a vibration damping device according to a first embodiment of the present invention.

Referring to FIGS. 5A, 5B, 6, 7, 8, 9, and 10, a first embodiment of the vibration isolation device of the present invention includes a plurality of vibration isolation assemblies 20a, 20b, 20c, ).

The base frame 10 has a shape in which it is disposed in contact with a lower surface of a target facility and has a hole 11 through which protrusive attachments such as a wheel or a leg of the target facility can be inserted.

In the illustrated example, the hole 11 is arranged at the central portion so that four wheels or legs can be inserted. However, the shape and structure of the hole 11 are not limited to this, and may be one hole or a number of holes corresponding to the number of attachments on the bottom surface of the equipment. In the illustrated example, the shape of the hole 11 is similar to "X ", which provides a mounting position of the anti-vibration assemblies 20a and 20b as described later, The hole 11 can be provided. That is, the wheel or leg positions of many facilities can be inserted into the holes 11 of the base frame 10 shown in the example.

The base frame 10 may be made of a rigid material such as a metal material. As in the illustrated example, the base frame 10 supports the facility by interposing the upper surface 13 surrounding the hole 11 between the lower surface of the facility and the ground (or bottom surface). Therefore, the top surface 13 may be in contact with the lower surface of the lower edge of the equipment at least so that the equipment can be supported in a balanced manner, but the present invention is not limited thereto.

A plurality of dustproof assemblies 20b and 20d are coupled to the lower surface of the base frame 10. The plurality of vibration-proof assemblies 20b and 20d are disposed at a plurality of locations and are coupled to the base frame 10 using a method such as a screw or welding. In the illustrated example, the anti-vibration assemblies 20b, 20d each show a configuration in which two and four rubber mount elements 22 are disposed, but are not limited thereto.

The dustproof assemblies 20a and 20b have a predetermined thickness so that the wheels or legs of the target equipment inserted in the holes 11 of the base frame 10 are spaced from the ground. Thereby, the object facility can be left on the dustproof device of the present invention without removing the protruding attachment to the lower surface. 8 shows a state where the wheel R of the equipment is inserted into the hole 11 of the base frame 10 when the first embodiment of the anti-vibration device of the present invention is installed in the target facility for the sake of understanding. Fig. The wheel R of the equipment is inserted into the hole 11 of the base frame 10 and is lower in height than the dustproof assemblies 20a and 20b so as to be spaced apart from the ground surface .

The rubber pads 212 may be coupled to each other with the intermediate plate 214 of the multilayer pad portion 21 interposed therebetween. The rubber pads 212 may have a plurality of grooves 2121 each having a concavo-convex shape in its bottom surface.

In addition, a plurality of rubber mount elements 22 are disposed on the multilayer pad portion 21. In the illustrated example, one to four rubber mount elements 22 are disposed according to the location at which they are installed. An upper plate 213 is disposed on the multilayer pad portion 21 and rubber mount elements 22 are disposed on the upper plate 213.

The rubber mount elements 22 may be air-filled configurations, but are not limited thereto. The rubber mount elements 22 can perform vibration control operations individually on the multilayer pad portion 21. This configuration can perform a control operation not only to disperse vibration and impact, but also to mitigate or prevent vibration in the horizontal, vertical, and their mixing directions together with the multilayer pad portion 21. [

The cover part (23) is joined to the rubber mount element (22) by a coupling means (231). The engaging means 231 may be, for example, in the form of forming a screw hole in the cover portion 23 and engaging the cover portion 23 with the rubber mount element 22 through a screw. As shown in FIG. 1A, the coupling means may overlap with the first coupling hole 121 for coupling with the target facility. In this case, the cover portion 23 and the rubber mount element 22 may be engaged with each other at the same time as using the single screw or bolt.

The vibration-proof assemblies 20a and 20b are fixedly installed at predetermined positions on the lower surface of the base frame 10, as described above. The vibration-proof assemblies 20a and 20b may be arranged so as to be mutually symmetrical in the base frame 10.
