Description

The present invention relates to a honeycomb work board.

More specifically, for example, in a clean room,
Attach various measuring instruments to the desired combination and perform the measurement work of precision instruments such as optical instruments.
The present invention relates to a honeycomb work board having a built-in anti-vibration device capable of performing high-precision measurement work.

"Prior art" As such a honeycomb working board, generally, a surface member made of a steel plate is joined to both surfaces of an aluminum honeycomb material constituting a main body, and a predetermined distance is provided between upper surface members. Therefore, a large number of screw holes are provided to penetrate. By the way, using such a honeycomb working board, particularly, when performing high-precision measuring work, for example, an external force is applied to a precision instrument, a measuring instrument, or the like attached to the honeycomb working board, and vibration occurs in these. In such a case, it is necessary to stop the vibration immediately because the work cannot be performed. However, the conventional honeycomb working panel does not have a vibration isolating function itself, and therefore, when performing such work, a supporting device incorporating a vibration isolating device using an air spring system is usually used. The honeycomb work board was set on the table, and such work was performed.

"Problems to be Solved by the Invention" By the way, in such a conventional honeycomb working panel, since the main focus is on lightness, the thickness of the upper surface member is required to maintain planar accuracy. Can be done,
As thin as possible to firmly attach measuring instruments, etc.
That is, it is generally set to about 5 mm. Therefore, it is possible to prevent the planar accuracy of the honeycomb working board from being impaired,
In most cases, in order to facilitate molding and the like, molding is performed by providing a number of screw holes in the surface member in advance and then joining the surface member to an aluminum honeycomb material via an adhesive.

Further, the length under the neck of a mounting screw for mounting a measuring device or the like is, for example, a measuring device in a screw hole in which a cell wall forming a cell of an aluminum honeycomb material and a screw hole are opposed to each other. When mounting the device, the length of the cell wall is not damaged by the mounting screw, that is, the tip of the mounting screw does not protrude from the lower surface of the surface member when the measuring device or the like is mounted. As such, the length under the neck is set short.

By the way, since the lower surface of the surface member and the end of the cell wall forming each cell in the aluminum honeycomb material are joined via an adhesive,
Depending on the type of adhesive to be used, for example, whether a two-component resin adhesive or a film adhesive is used, or even when a two-component resin adhesive is used, the lower surface side of the surface member Or to apply to the end side of each cell wall of the aluminum honeycomb material, such as,
Further, depending on the position where the screw hole exists in the aluminum honeycomb material, that is, whether it is located opposite to the cell wall or the hollow portion of the cell, the result to be produced differs, but in most cases, , By heating and pressing at the time of joining,
A part of the adhesive once melted flows into the lower end of at least a part of the screw hole, and the injected adhesive is thereafter hardened and remains as it is in the screw hole. As a result, the screw thread at the lower end of the screw hole may be filled up with the adhesive over a considerable height.

Therefore, when mounting a measuring device or the like using such a screw hole, when the length of the mounting screw under the neck is firmly attached to the measuring device or the like, the tip of the threaded portion may be attached to the lower surface of the surface member. Even though the length is set so that it does not protrude, when the mounting screw is screwed into the screw hole, the adhesive that has adhered in the screw hole due to the screwing of the mounting screw will not Is shaved. Most of the powdered adhesive that has been scraped falls into the cell and stops as it is.

By the way, in a clean room, the positive pressure inside the room is usually about 1.
In addition to being controlled at 4 atmospheres, the temperature, humidity, etc. are also controlled to maintain a predetermined state at all times.

Therefore, in such a clean room, when performing various measurement work of precision equipment using a honeycomb work board, for example, a powdery adhesive or the like is present in a stopped state in the cells of the honeycomb work board. In such cases, the powdery adhesives, etc., which had existed in the cell until now, flew up due to the convection of air in the clean room, and when vibrations occurred in the honeycomb work board, etc. May be scattered into the clean room via the screw holes located in communication with the clean room. If powdery adhesive or the like is scattered, the cleanliness of the clean room will be reduced, the function of the clean room will be impaired, and the measurement equipment and precision equipment will be soiled. It was pointed out.

Therefore, in order to solve the above-mentioned problems, when the measuring instrument is firmly attached, for example, a screw thread located at the lower end of the screw hole used for the attachment adheres over a considerable height. Even if it is buried with an agent, a surface member having a length that does not cause a situation in which the tip of the mounting screw comes into contact with the attached adhesive is used. A screw that has a depth such that the tip of the mounting screw does not come into contact with it when a measuring device or the like is mounted by mounting a screw hole through the mounting hole Perforated honeycomb work boards have been tried. However, in such a honeycomb work panel,
Even if it is used in a clean room, there is no situation that degrades the function of the clean room,
In any case, since the weight of the surface member is significantly increased, there is a disadvantage that the lightness, which is the main purpose of the honeycomb working board, is impaired, and in particular, in the latter, screw hole processing is troublesome and costly. There was a problem.

In addition, in the above-mentioned conventional work panels, none of the types have a vibration-proof function, and therefore, it is extremely difficult to perform a highly accurate measurement work using the honeycomb work panel alone. Therefore, when performing such work, a complicated support base having a built-in vibration damping device using an air spring system is necessary. It was pointed out that he became heavier.

The present invention has been made in view of the above circumstances, and its purpose is to impart a vibration-proofing function to the honeycomb work board itself without substantially impairing the lightness which is the main purpose of the honeycomb work board, and to increase the cost, And, without using a support stand with a heavy anti-vibration function, the honeycomb work board alone,
High-precision measurement work can be performed, and even when used in a clean room, there is no situation that degrades the function of the clean room.
It is still another object of the present invention to provide a honeycomb working board that can be easily formed.

"Means for Solving the Problems" The present invention has been made to achieve the above object, and the technical solutions thereof are as follows.

The honeycomb working board according to the present invention has a honeycomb member formed of a planar aggregate of hollow columnar cells, and surface members respectively joined to upper and lower cell end surfaces of the honeycomb member, and The upper surface member is a metal surface plate having a predetermined thickness provided with a large number of screw holes penetrating therethrough at a predetermined interval, and a gel made of silicone having an appropriate thickness. And a support plate made of a plate lighter than the surface plate.

[Operation] The present invention comprises the above means, and operates as follows.

That is, in the honeycomb working board according to the present invention, the surface member joined to the upper side of the honeycomb material forming the main body has a predetermined thickness in which a large number of screw holes are provided at predetermined intervals. Material, a vibration-absorbing material layer made of a gel-like substance made of silicone having an appropriate thickness, and a support plate lighter than the surface plate are stacked in order from the top. Has become.

Therefore, in this honeycomb working board, the surface plate and the support plate surface constituting the upper surface member are provided with a vibration-proof material of an appropriate thickness made of a gel material made of silicone having excellent vibration-proof properties. Since the layer is provided, for example, an external force is applied to the surface plate or a measuring device attached to the surface plate, and even if vibration is generated, these vibrations are greatly attenuated by the vibration isolator layer, Vibrations transmitted to the support plate rarely occur, and vibrations generated on the surface plate and the like are stopped almost instantaneously.

Therefore, high-precision measurement work can be performed even when only the honeycomb work board is used alone without using a support base in which an anti-vibration device using an expensive and heavy air spring system is incorporated. Can be implemented.

Further, in forming the upper surface member, when a vibration damping material layer made of a gel material made of silicone is laminated in an interposed state between the surface plate and the supporting plate, the vibration damping material made of the gel material is used. Since the material layer has excellent tackiness in that situation, it can be directly bonded to the face plate and the support plate only by pressing in most cases without using other adhesives. Conventionally, even when the screw holes are provided through, a surface member provided with a large number of screw holes is conventionally caused when the surface member is joined to the honeycomb material via an adhesive. There is no possibility that the thread at the lower end of the screw hole of the portion is filled with the adhesive.

Therefore, the surface plate having a predetermined thickness, that is, the thickness of the surface plate, the conventional mounting screw is set as short as possible under the neck length is possible to firmly attach the measuring instrument and the like, When the mounting screws having the same length under the neck are used, the thickness can be set to be the same as the thickness of the upper surface member of the conventional general honeycomb work board.

Therefore, this honeycomb work panel is substantially equal to the vibration-proof material layer and the support plate as compared with the conventional general honeycomb work board, but the weight is increased, but the support plate is made of a lighter plate than the surface plate. In addition, since the weight of the vibration damping material layer is different from that of the metal material and the like, the weight is slightly increased. Further, when compared with the conventional improved honeycomb working board, its weight is extremely light.

Further, since the screw holes provided in the surface plate can be provided in advance by penetrating, the formation of the upper surface member is easy.

Furthermore, in this honeycomb working panel, the lower surface of the screw hole in the surface plate is closed by the vibration-proof material layer,
Since the vibration-proof material layer is adhered to the surface plate by utilizing the adhesiveness of the vibration-proof material layer, when the mounting screw is screwed into the screw hole, the mounting screw may cut off the adhesive. There is no danger at all. Therefore, even if this honeycomb work panel is used in a clean room, the function of the clean room is not impaired.

"Example" Hereinafter, the present invention will be described based on an example shown in the drawings.

FIG. 1 is a longitudinal sectional view of a main part of the honeycomb working board, and FIG. 2 is a partially cutaway perspective view of the honeycomb working board.

 First, the configuration and the like will be described.

Reference numeral 1 denotes a honeycomb work board, and the honeycomb work board 1
Is an aluminum honeycomb material 2 formed of a planar assembly of hollow columnar cells 3 and upper and lower cells 3 of the aluminum honeycomb material 2.
Has surface members 5 and 6 joined to each other with an adhesive 15 at the end faces.

To describe these in detail, first, the aluminum honeycomb material 2 constituting the main body portion is made of a foil-shaped aluminum material as a base material, and a predetermined number of the base materials are adhered to each other in a predetermined positional relationship, and are laminated. This is formed by expanding the cell in the direction of the attachment, and is formed of a planar aggregate of substantially regular hexagonal hollow columnar cells 3 having a predetermined cell size and height formed by the cell walls 4, and is lightweight. In addition to excellent properties, it also has excellent weight ratio strength and excellent planar accuracy.

Reference numeral 5 denotes a surface member joined to the upper end surface of the cell 3 in the aluminum honeycomb material 2, and the upper surface member 5
Has a surface plate 7, an anti-vibration material layer 9, and a support plate 10 laminated in order from the top. The surface plate 7 of the surface member 5 has a size such that its periphery slightly extends from the aluminum honeycomb material 2, and a large number of screw holes 8 penetrate therethrough at predetermined intervals over substantially the entire surface. As long as it is possible to firmly attach the measuring device 12 to a predetermined thickness, that is, to a mounting hole 14 formed in the mounting edge 13 of the measuring device 12, Insert the mounting screw 11 whose lower length 1 is set short, and
When the measuring instrument 12 is firmly attached to the surface plate 7, the tip of the screw portion of the mounting screw 11 is located slightly inside the surface plate 7 without protruding from the lower surface of the surface plate 7. It is formed of a stainless steel plate having a thickness capable of forming the same. The support plate 10 has the same size as the aluminum honeycomb material 2 and is made of a metal plate such as an aluminum plate which is lighter and more lightweight than the surface plate 7 and whose thickness is set to be considerably thinner. The surface plate 7 and the support plate
A vibration damping material layer 9 having an appropriate thickness made of, for example, a gel-like substance made of silicone such as αGBL (registered trademark of Seagel Co., Ltd.) is laminated between the base material 10 and the base material 10. .

By the way, in forming the vibration damping material layer 9 made of a gel material made of silicone which is laminated between the surface plate 7 and the support plate 10, a two-component It can be formed by mixing raw materials in appropriate proportions, injecting them into molds and the like, and pressurizing (and heating if necessary), and has excellent anti-vibration properties and excellent adhesiveness doing.

Therefore, when the upper surface member 5 is formed, a vibration isolator layer 9 having the same size and an appropriate thickness as the surface plate 7 is formed in advance, and this vibration isolator layer 9 is The surface plate 7 and the support plate 10 are stacked via the vibration-insulating material layer 9 without using another adhesive by being set in an interposed state between the face plate 7 and the support plate 10 and applying pressure. 5 is formed.

In addition, without forming the vibration isolator layer 9 in advance, for example, on the lower surface of the surface plate 7 surrounding the circumference at an appropriate height and closing the lower surface of each screw hole 8 with a tape or the like, as appropriate. After injecting an appropriate amount of raw materials mixed in proportions, the support plate 10
And pressurizing to form the vibration isolating material layer 9, and at the same time, the surface member 5 may be formed by laminating each member.

The thickness of the vibration isolating material layer 9 laminated between the surface plate 7 and the support plate 10 varies depending on the size, use, and the like of the honeycomb work board 1. When an external force is applied to the measuring device 12 or the like attached to the face plate 7 and these are vibrated, the vibrations are greatly attenuated by the vibration isolating material layer 9, and the transmission of the vibrations to the support plate 10 is almost prevented. The thickness may be set so that the vibration generated on the surface plate 7 and the like can be stopped almost instantaneously.

Reference numeral 6 denotes a surface member made of a metal plate having the same size as the aluminum honeycomb material 2 joined to the end surface of the cell 3 on the lower side of the aluminum honeycomb material 2. Reference numeral 16 denotes a side plate made of a metal plate provided on a side surface portion of the honeycomb work board 1. The side frame 16 includes an upper side frame 16a hanging down around the surface plate 7, and an upper side frame 16a. An aluminum honeycomb material 2 and a lower side frame 16b joined to the side of the lower surface member 6 are located inside the side frame 16a. Therefore, in the honeycomb working board 1, for example, when vibration occurs on the front board 7, only the front board 7 laminated on the upper surface of the vibration-proof material layer 9 can swing.

 The honeycomb work board 1 is configured as described above.

 Next, the operation and the like will be described.

The honeycomb working board 1 has a surface member 5 joined to an upper side of an aluminum honeycomb material 2 constituting a main body, and has a predetermined thickness in which a large number of screw holes 8 are provided at predetermined intervals. A surface plate 7 made of a stainless steel plate having a thickness; a vibration-proof material layer 9 made of a gel-like material made of silicone such as αGEL having an appropriate thickness; Further, the support plate 10 is formed by laminating a support plate 10 formed of a metal sheet such as an aluminum plate which is considerably lighter in order from the top.

Therefore, in the honeycomb working board 1, since the vibration damping material layer 9 having excellent vibration preventing properties is provided between the surface board 7 constituting the upper surface member 5 and the support plate 10, for example, Even if an external force is applied to the surface plate 7 or the measuring device 12 attached to the surface plate 7 and the vibration is generated, the vibration is greatly attenuated by the vibration isolating material layer 9.
Vibration is hardly transmitted to the support plate 10, and the vibration generated on the surface plate 7 and the like is stopped almost instantaneously.

Therefore, even if only the honeycomb work board 1 is used alone without using a support base in which an anti-vibration device using an expensive and heavy air spring system is incorporated, high-precision measurement work can be performed. Can be implemented.

Further, when forming the upper surface member 5, when the vibration damping material layer 9 is laminated between the surface plate 7 and the support plate 10, the vibration damping material layer 9 made of the gel-like substance is It has excellent tackiness itself, even without using other adhesives separately.
Since it is possible to directly adhere, even if a screw hole is provided through the surface plate 7 in advance, conventionally, a surface member provided with a large number of screw holes is conventionally provided with an adhesive. Thus, there is no possibility that the thread at the lower end of some of the screw holes generated when joining to the aluminum honeycomb material is filled with the adhesive.

Therefore, the thickness of the surface plate 7 is the same as that of a conventional mounting screw whose under-neck length is set as short as possible so that the measuring instrument 12 or the like can be firmly mounted. When the screw 11 is used, the thickness can be set to be the same as the thickness of the upper surface member in a conventional general honeycomb work board.

Therefore, the honeycomb work board 1 has a weight that is substantially equivalent to that of the conventional honeycomb work board and substantially corresponds to the vibration damping material layer 9 and the support plate 10, but the support plate 10 is more movable than the surface plate 7. It is made of a lightweight metal plate, and its thickness is set to be considerably thinner than that of the surface plate 7. Further, unlike a metal material, the vibration-proof material layer 9 has a light weight, so that the weight increases. Minutes are small. Further, when compared with the conventional improved honeycomb working board, its weight is extremely light.

The screw holes 8 provided in the surface plate 7 are
Since the surface member 5 can be provided so as to penetrate, it is easy to form the surface member 5.

Further, in the honeycomb working board 1, the lower surface of the screw hole 8 in the surface plate 7 is closed by the vibration-proof material layer 9, and the vibration-proof material layer 9 is formed by utilizing the adhesiveness of the vibration-proof material layer 9 itself. Since it is adhered to the face plate 7, when the mounting screw 11 is screwed into the screw hole 8, there is no possibility that the adhesive adhered in the screw hole 8 is scraped off. Therefore, even if such a honeycomb working panel 1 is used in a clean room, the function of the clean room is not impaired.

 The above is the description of the operation and the like.

"Effect of the Invention" The honeycomb working board according to the present invention, as described in detail above,
A surface member joined to the upper side of the honeycomb material, a metal surface plate having a predetermined thickness provided with a large number of screw holes penetrating at predetermined intervals, and a silicone having an appropriate thickness The following effects are exhibited by the fact that the vibration-proof material layer made of a gel-like substance and the support plate formed of a plate lighter than the surface plate are laminated in order from the top. .

That is, since the honeycomb working board has an excellent vibration isolating function itself, the honeycomb working board itself is expensive, and without using a support base in which a heavy vibration isolating device is incorporated.
By using only the honeycomb work panel, it is possible to perform particularly high-precision measurement work, and when this honeycomb work panel is used in a clean room, there is a risk that the function of the clean room may be impaired. It is undeniable that the weight becomes slightly heavier than that of the honeycomb work board, but even when used in a clean room, compared to the conventional improved honeycomb work board, which does not impair the function of the clean room at all. It is extremely lightweight, so that the lightness, which is the main focus of the honeycomb work board, is hardly impaired, and even when used in a clean room, the function of the clean room is not reduced at all, and The molding is also easy.

As described above, the effects exhibited by the present invention are remarkable and large, for example, the problems existing in this type of conventional example are eliminated.
