DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a fixing device according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a fixing base constituting the fixing device of the present invention. The fixed base 1 mainly includes a frame 2, a sheet material 3, and an adjusting screw 5. Sheet material 3
Is mounted on a support portion 4 (see FIG. 8) described later. The support part 4 is installed in the frame 2. On the upper surface of the frame 2, four convex portions 21 are attached.

The support 4 is fixed to the frame 2 by adjusting screws 5. In addition, the height position of the support part 4 with respect to the frame 2 is adjustable. This will be specifically described below.

On the side surface of the frame 2, a vertically long hole 22 is formed. The adjusting screw 5 screws the support 4 to the frame 2 via the hole 22. The height dimension of the hole 22 is sufficiently larger than the height dimension of a portion of the adjusting screw 5 that penetrates the hole 22. Thus, the adjusting screw 5 can screw the support portion 4 through the hole 22 at different height positions on the side surface of the frame 2.

The height of the support member 4 with respect to the frame 2 can be adjusted on the fixed base 1, so that the height of the sheet material 3 with respect to the frame 2 can be adjusted.

In the fixed base 1, the plurality of projections 21
The upper ends are configured to have the same height. Then, in the fixed base 1, by using a specific holding plate, the upper end of the material to be processed is moved to
Can be aligned with the height of the upper end of the. The material to be processed as referred to herein is a material to be processed, for example, a material that is subjected to processing such as cutting or embossing by a predetermined machine such as a processing head.

FIG. 2 shows a perspective view of an example of a holding plate used for the fixing base 1. As shown in FIG. The holding plate 50 mainly includes an upper plate 52, a lower plate 53, and a handle 51. The handle 51 is mounted on the upper plate 52. The lower main surface of the upper plate 52 faces and is fixed to the upper main surface of the lower plate 53. The upper plate 52 and the lower plate 53 are attached by a connecting member 54.

The connecting member 54 includes an upper plate 52 and a lower plate 53.
Are fixed at certain intervals, and are made of rubber, sponge, resin, or the like. Then, the connecting member 54
Is fixed between the upper plate 52 and the lower plate 53 by, for example, an adhesive.

Next, a method for fixing the work material on the fixed base 1 by using the pressing plate 50 on the fixed base 1 will be described.

First, referring to FIG.
Is placed on the sheet material 3. Then, as shown in FIGS. 4 and 5, the adjusting screw 5 is operated while the holding plate 50 is located on the upper portion of the fixing base 1, so that the
Then, the support part 4 is fixed. FIG. 4 is a diagram of the fixed base 1 and the holding plate 50 as viewed from obliquely above. Also,
FIG. 5 is a view of the fixed base 1 and the holding plate 50 as viewed from the right side.

Specifically, when the holding plate 50 is positioned on the fixed base 1, the four convex portions 21 and the material to be processed are formed by the main surface of the holding plate 50 below the lower plate 53. Align the 90 height positions. Here, the support part 4 can move with respect to the frame 2 unless it is completely fixed by the adjustment screw 5. In other words, if the support member 4 is not completely fixed by the adjusting screw 5, the support member 4 changes its height position by pressing the work material 90 downward (in the direction of the arrow X in FIG. 5) by the pressing plate 50. Is done.

Then, the four convex portions 21 and the work material 90
When the height positions are aligned, the adjusting screw 5 is operated to completely fix the support 4 to the frame 2.

The sheet material 3 is made of chloroprene rubber. The hardness of the sheet material 3 is JIS hardness Hs (JISA)
25 ° to 35 ° is preferred. In addition, as the sheet material 3, natural rubber, isoprene rubber, styrene rubber, butyl rubber, butadiene rubber, ethylene propyl rubber, nitrile rubber, urethane rubber, or the like can be used. In addition, since all are easily available, JIS hardness Hs
(JISA) Soft rubber of 40 ° or less.

By forming the sheet material 3 from the above-mentioned materials, the work material 90 is brought into close contact with the entire surface of the sheet material 3. As a result, the work material 90 is placed on the fixed base 1.
Are fixed so that the upper end thereof is at the same height as the upper end of the projection 21.

The size of the main surface of the sheet material 3 is, for example,
92 (mm) × 98 (mm) [(groove 3B in FIG. 9)
(Direction) × (dimension of groove 3C direction)]. For example, 90 (mm) × 90
When a brass plate of (mm) × 20 (mm) [dimension of (groove 3B direction) × (groove 3C direction) × (direction perpendicular to the surface of the sheet material 3) in FIG. 9) is used, the hardness Hs ( JIS
When chloroprene rubber with A) of 30 ° is used as the material of the sheet material 3, the work material 90 can be firmly fixed. Further, even when chloroprene rubber having a hardness Hs (JISA) of 25 ° is used as the material of the sheet material 3 with respect to the same work material 90, when the fixed base 1 is vibrated, the work material 90 Although the material is slightly vibrated, the material to be processed 90 can be fixed without any problem when processing the material to be processed 90.

The sheet material 3 for the material 90 to be processed is
Although the adhesive strength of the steel sheet varies depending on the material of the work material 90, in addition to the brass described above, gold, silver, copper, platinum,
Even when a plate material such as aluminum, iron, or stainless steel is used as the work material 90, it is possible to fix the work material 90 on the sheet material 3. Particularly, in the present embodiment, since chloroprene rubber is used for the sheet material 3, the sheet material 3
Has excellent abrasion resistance, aging resistance, light resistance, ozone resistance,
It can withstand long-term use without special handling.

When the work material 90 is pulled perpendicular to the surface of the sheet material 3, the work material 90 is easily peeled off from the sheet material 3.

On the upper surface of the sheet material 3, as shown in FIG.
Further, grooves are formed in a lattice pattern. Such grooves prevent air from accumulating between the work material 90 and the upper surface of the sheet material 3 and weakening the adhesive force. For example, when a transparent sheet is fixed on the sheet material 3, no matter how carefully the transparent sheet is installed, some air remains between the sheet material 3 and the transparent sheet, and bubbles are formed. Become like In such a case, in order to remove the air bubbles, conventionally, the air bubbles were removed by piercing the air bubbles in the transparent sheet with a needle or the like. However, in the present embodiment, the air can be removed through the above-described groove.
For example, when a bubble is generated, the portion is rubbed with a finger and extruded into a groove portion, so that air forming the bubble flows through the groove from a portion where the sheet material 3 and the transparent sheet are bonded. You will go outside. as a result,
The degree of adhesion between the work material 90 and the sheet material 3 can be increased.

In the lattice-shaped grooves, the vertical center line and the horizontal center line of the sheet material 3 are different from the other lines formed by solid grooves, while the broken line grooves 3B , 3C. Therefore, by predicting the intersection of the broken lines 3B and 3C, the center point of the sheet material 3 can be predicted. Therefore, even when the center point of the sheet material 3 is hidden by the work material 90, it is possible to know how much the work material 90 is displaced from the center point. The work material 90 can be placed easily and accurately at the center of the sheet material 3.

In the center of the sheet material 3 on the grid,
A circular mark 3A is formed. Furthermore, sheet material 3
Circular marks 3A are formed at predetermined intervals on the diagonal line of the area where the lattice-shaped grooves are formed. Therefore, the work material 90 can be positioned more easily and more accurately, and the size and the like of the work material 90 can be easily grasped. The mark 3A is
It may be a linear shape similar to a lattice-shaped groove, or may be a simple mark other than a circle.

As described above, by using the fixing base 1 and the holding plate 50, the workpiece 90 can be fixed at a specific height regardless of the thickness of the workpiece 90. Therefore, by fixing the fixing base 1 to a predetermined machine such as a processing head in a specific positional relationship, the workpiece 90 can be always fixed to the above-described predetermined machine in a specific positional relationship. .

In the fixing table 1, the upper end of the workpiece 90 is aligned not with the upper end of the frame 2 but with the upper end of the projection 21. As a result, the material 9 to be processed can be more accurately determined.
The vertical alignment of 0 can be performed. This is because the upper end of the convex portion 21 is much smaller in surface area than the upper end of the frame 2, and it is easier to form a uniform, uneven surface.

Next, the structure of the fixed base 1 will be described in detail with reference to FIGS. FIG. 6 is a plan view of the fixed base 1. FIG. 7 is a perspective view of the frame 2. FIG. 8 is a perspective view of the support portion 4 housed in the frame 2. FIG. 9 is a plan view of the sheet material 3. FIG. 10 is a perspective view of a fixture attached to the support part 4, and FIG. 11 is a perspective view of the support part 4 together with the fixture of FIG.
FIG. 5 is a perspective view of a connection member attached to the device.

The frame 2 is composed of four front, rear, left and right wall surfaces. The support part 4 is mainly composed of a housing including four wall surfaces in front, rear, left and right. The support portion 4 is installed in the frame 2 such that the front, rear, left, and right side surfaces face the front, rear, left, and right inner walls of the frame 2.

Incidentally, two grooves 23 are formed in the longitudinal direction on the inner wall on the rear side of the frame 2. Further, two projections 46 are formed on the rear side surface of the support portion 4 in the vertical direction. The support portions 4 are stably held in the frame 2 by fitting the protrusions 46 into the grooves 23, respectively.

The upper surface of the support portion 4 is a substantially square, substantially horizontal plane. Further, a wall 47 is provided on an outer peripheral portion of the support portion 4. And the sheet material 3 is
It is installed on the upper surface of the support part 4 and inside the wall 47.

Claws 41 to 45 are attached to the front surface of the support portion 4. The claws 41, 42 have a main surface along the vertical direction, and have a convex portion at the front. The claws 43 to 45 have main surfaces along the horizontal direction. Note that the claw 43 is
The pawls 44 and 45 are located near the upper end of the support 4.

The connecting member 7 shown in FIG. 11 is fitted inside the fixture 6 shown in FIG. 10, and is attached to the front surface of the support 4 together with the fixture 6.

The attachment 6 is configured so that the plate is bent and a concave portion is formed at the center. Specifically, the attachment 6 includes a center plate 66 located at the center of the attachment 6, side plates 65, 67 connected to both left and right ends of the center plate 66 and perpendicular to the center plate 66, and side plates 65, 65. 67
And end plates 64 and 68 which are connected to the front end and are perpendicular to the side plates 65 and 67, respectively. And the mounting fixture 6
Is formed with a circular hole 61 in the center of a center plate 66 and rectangular holes 62 and 63 in side plates 65 and 67.
The attachment 6 is made of, for example, a synthetic resin.

The connection member 7 is made of, for example, metal. The shape of the connection member 7 is a rectangular parallelepiped. In addition,
A hole 71 is formed in the front surface 70 of the connection member 7.

FIG. 12 is a sectional view of the connecting member 7 shown in FIG.
It is arrow sectional drawing along XII line. The shape of the hole 71 is substantially cylindrical. However, the tip portion 71 which is the tip of the hole 71
A has a conical shape. That is, the hole 71 has a substantially cylindrical shape, but the tip (located inside the connection member 7) is sharp.

In the fixing stand 1, first, the connecting member 7 is attached to the fixture 6 such that the front surface 70 faces the inner surface of the center plate 66 of the fixture 6. At this time, the hole 71 of the connection member 7 is opposed to the hole 61 of the fixture 6.

The connecting member 7 attached to the attachment 6 is attached to the support 4 so as to be sandwiched between the claws 43 to 45 in the vertical direction. At this time, the claws 41 and 42 are fitted into the holes 62 and 63 of the attachment 6, respectively.

FIG. 13 shows XIII-X of the fixing table 1 of FIG.
It is arrow sectional drawing which follows the III line. In the fixed base 1,
A support 4 is provided inside the frame 2. Support part 4
The sheet material 3 is installed on the upper surface of the sheet. Also, frame 2
A bottom plate 25 is attached to the bottom of the.

A spring 8 is provided between the bottom plate 25 and the support 4. The springs 8 are provided at one position in front, rear, left and right, that is, at four positions.

The connecting member 7 is mounted on the front surface of the support section 4 together with the mounting tool 6. And the adjustment screw 5
The holes 22, 61, 71 penetrate. By changing the height position of the adjusting screw 5 in the hole 22, the support portion 4 is adjusted.
The height position at which is fixed can be changed. The support 4
Is urged upward by a spring 8. That is, the spring 8 acts to assist the fixing of the support portion 4 by the adjusting screw 5.

The ball 9 is attached to the tip 71A of the connecting member 7. FIG. 14 shows an enlarged view of the vicinity of the connection member 7 in FIG.

Since the spherical contact member 9 is attached to the distal end portion 71A, the distal end surface 5A of the adjusting screw 5 comes into contact with the member directly attached to the support portion 4 at a point. Thus, the rotational force of the adjustment screw 5 is less likely to be transmitted to the support portion 4 than when the distal end surface 5A of the adjustment screw 5 is in surface contact with a member directly attached to the support portion 4. Since the rotational force of the adjusting screw 5 is hardly transmitted to the supporting portion 4 side, the supporting portion 4 rotates with the rotation of the adjusting screw 5 when the supporting portion 4 is fixed, and the upper surface thereof is shifted from a horizontal plane. Can be avoided.

If the upper surface of the support portion 4 deviates from the horizontal plane, there arises a problem that the workpiece 90 on the sheet material 3 is distorted and fixed in the horizontal direction. And
In the fixed base 1, such a problem can be avoided because the contact member 9 is attached.

When the contact member 9 contacts at least the tip surface 5A with an area smaller than the tip surface 5A, the rotational force of the adjusting screw 5 becomes smaller than when the contact member 9 contacts with the same area as the tip surface 5A. It is considered that it is difficult to be transmitted to the support portion 4 side. However, the contact member 9 can minimize the area in contact with the distal end surface 5A by contacting the distal end surface 5A with a spherical surface.

Further, in the fixing base 1, the adjusting screw 5 for fixing the support 4 applies a force in the direction of arrow P to the support 4 via the connecting member 7 instead of directly. That is, the connection member 7 acts so as to buffer the force in the direction of the arrow P applied to the support portion 4. Thereby, the support portion 4
However, it is possible to avoid being bent as a result of being compressed and contracted by the adjusting screw 5 and the frame 2 as much as possible. Note that the connection member 7 does not necessarily need to be provided separately from the support 4.

Next, regarding the structure of the bottom surface of the fixed base 1,
explain. FIG. 15 is a bottom view of the fixed base 1. Bottom plates 24 and 25 are fitted on the bottom surface of the fixed base 1. The bottom plates 24 and 25 exist on the same plane. That is, the bottom plates 24 and 25 support the bottom surface of the fixed base 1 while being divided into left and right sides.

The bottom plates 24, 25 are attached to the frame 2 by screws 24A, 24B, 25A, 25B, respectively. The bottom plates 24 and 25 respectively have
Holes 24C, 24D, 25C, and 25D are formed one at each of the front and rear, that is, at two locations (a total of four locations).

The holes 24C, 24D, 25C, 25D
Has an upright outer periphery. The springs 8 (see FIG. 13) are fitted into the cutouts on the outer periphery of the holes 24C, 24D, 25C, and 25D, respectively.

FIG. 15 shows a state in which the support 4 is not completely fixed to the frame 2. In this state, a gap having a dimension x exists between the bottom plate 24 and the bottom plate 25 in the horizontal direction (the double-headed arrow P in FIG. 15).

FIG. 16 is a bottom view of the fixed base 1 in a state where the support portion 4 is completely fixed to the frame 2. FIG.
, The size y of the gap between the bottom plate 24 and the bottom plate 25
Is smaller than the dimension x in FIG. This is for the following reason.

That is, when the support portion 4 is fixed to the frame 2,
Since the adjusting screw 5 is screwed into the inside of the frame 2, the dimension of the frame 2 in the vertical direction (the double arrow Q in FIGS. 15 and 16) is extended accordingly. The reason is that the frame 2 receives a force such that the dimension in the horizontal direction (the double-headed arrow P in FIGS. 15 and 16) decreases with this elongation.

In the fixed base 1, from FIGS. 15 and 16,
When the support portion 4 is fixed to the frame 2 by the adjusting screw 5, a force is applied so that the size of the bottom surface in the direction of the double arrow P is reduced by (xy). When the support 4 is not completely fixed to the frame 2, the dimension x, that is, “x”, is provided between the bottom plate 24 and the bottom plate 25 in the direction of the double arrow P.
There is a gap having a size larger than “−y”.

Thus, in the fixing base 1, while the bottom surface is reinforced by the bottom plate 24 and the bottom plate 25, the bottom surface is prevented from bending due to a change in the size of the bottom surface based on the fixing of the support portion 4. .

When the support portion 4 is fixed, the bottom plate 24 in a state where the support portion 4 is not completely fixed to the frame 2 so that the bottom surface of the fixing base 1 is reinforced more firmly. It is preferable that the gap between the bottom plates 25 is "xy" in the direction of the double arrow P. Thereby, in a state where the support portion 4 is completely fixed to the frame 2, the bottom plate 24 and the bottom plate 25 cover the bottom surface of the fixing table 1 without any gap in the double arrow P direction.

Next, the structure of the holding plate 50 will be described in detail. FIG. 17 shows a plan view of the holding plate 50.
FIG. 18 shows a side view of the holding plate 50.

As described above, the handle 51 is attached to the upper plate 5
2 at the center in the left-right direction. Also, the upper plate 5
Between the 2 and the lower plate 53, connecting members 54 are attached at four places.

The dimensions of the upper plate 52 and the lower plate 53 are
Are considered equal. Then, the four connecting members 54
Are mounted symmetrically on the upper plate 52.

Thus, as shown in FIG. 5 and the like, when a force is applied from the pressing plate 50 to the projection 21 of the frame and the upper end of the workpiece 90, the force is applied uniformly over the entire surface of the lower plate 53. . From the upper plate 52, a plurality of connecting members 5
This is because the force is evenly transmitted to the lower plate 53 through the fourth plate 53.

The number of connecting members 54 needs to be two or more. And the connecting member 54 is
It is necessary that the upper plate 52 be mounted symmetrically.

FIG. 19 shows a modification of FIG. FIG.
It is preferable that at least three connecting members 54 are attached as shown in FIG. This is because, if at least three connecting members 54 are attached, the force applied to the upper plate 52 is easily transmitted to the entire surface of the lower plate 53 via the connecting members 54 evenly.

The embodiments disclosed this time are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
