DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work support provided for supporting a work as a workpiece in a processing machine such as a laser processing machine.

[0002]

2. Description of the Related Art Conventionally, with respect to a work supporting table incorporated in a laser beam machine or the like, a large number of band-shaped plate pieces made of band-shaped metal pieces and the like are formed as a comb-shaped slit on a mounting member as an improved Kenzan type. It is known that the work piece is mounted in an upright state by being inserted into a work piece, and a work supporting surface is formed by the upper end portions of the strips. Further, as a further improved example of this type of work support using a band-shaped plate piece, the band-shaped plate piece is attached by bending it alternately in a wave-like manner, so that the band-shaped plate piece is resiliently actuated. It can reliably support the slit of the mounting member,
A technical means has been disclosed in which the attachment and replacement of the strip are easy and the rigidity of the strip can be increased (Japanese Patent Publication No. 3-31548). However,
Compared to the case where the conventional strip-shaped plate is attached to the mounting member without deforming, the conventional technique does not have any play by simply inserting the strip-shaped plate into each slit while flexing it in a wave shape. Although it is excellent in that the state and rigidity can be enhanced, the work of inserting the strip-shaped plate while bending the slit in the vertical state in a wavy manner is not so easy. In particular, if the number of mounting members that support the strips is increased in order to obtain the effect of bending, it is difficult to adopt a simple mounting method of manually inserting the strips while bending the strips sequentially from the ends. . Furthermore, since the band-shaped plate is used in a wave-like alignment, a wave-bottom space is created at both ends before and after the alignment, so that the peripheral portion is restricted as a support surface depending on the size of the waveform. There was also a disadvantage that it was easy.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional technical circumstances, and further improves the workability of the work of attaching the strip, and further improves the work of attaching the strip. The purpose of the present invention is to secure a stable mounting state without play and to enhance rigidity.

[0004]

According to the present invention, in order to solve the above-mentioned problems, at least one of the plurality of mounting members arranged at intervals has an angle of a slit formed in an adjacent mounting member. A technical means was adopted in which relatively different portions were provided, and the strip-shaped plate pieces were attached in a twisted state by being inserted into the slits. Further, as one specific example thereof, a slit formed in the mounting member is formed to be inclined with respect to a vertical direction, and the inclination directions of the slits formed in the adjacent mounting member are opposite to each other. The technical means of arranging the respective mounting members so as to make the belt-like plate pieces alternately twisted in the opposite direction by inserting them into their slits was adopted. In addition, a configuration may be adopted in which a convex portion is formed at an end of the strip-shaped plate piece, and the workpiece is supported via the convex portion.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is not limited to a specific form on the processing machine side as long as it relates to a work support of a processing machine such as a laser processing machine, and can be widely applied. . The strip-shaped plate used as a component of the work support table, such as a metal plate, on the support function of the work,
It is made of an appropriate plate material having necessary strength and appropriate elasticity. In this case, it is possible to increase the durability of the strip by adopting, for example, brass or high carbon steel having a high carbon content.
In addition, since the elastic state of the strip-shaped plate is affected by its own shape such as thickness and width, it is needless to say that the plate should be selected in consideration of these. When the strip is twisted, some deformation appears on the work supporting surface due to the deformation, but practically no hindrance occurs by suppressing the twist angle as described later. Further, in some cases, it is possible to form the end of the strip-shaped plate forming the supporting surface into an appropriate shape in advance so as to absorb the unevenness due to the twist. Also, as described above, a convex portion is formed at the end of the strip-shaped plate piece,
The support surface of the work may be formed by the projection.

As for the angle of the slit formed in the mounting member in a comb shape for inserting and mounting the band-shaped plate piece, as described above, at least the angle of the slit formed in the adjacent mounting member is relatively large. The belt-shaped plate piece may be attached in a twisted state even if it is partially provided by providing different portions in the slit. That is, the band-shaped plate piece may be twisted only between some of the plurality of mounting members, or may be twisted between all the mounting members. As for the twisting direction, the twisting direction may be the same, or the twisting direction may be changed alternately between the mounting members. In short, a technical means is adopted in which at least portions where the angles of the slits formed in the adjacent mounting members are relatively different are provided, and the strip is attached in a twisted state by being inserted into those slits. Anything should do. As a result, the strip-like plate is urged by the elastic force based on the elastic deformation caused by the torsion so as to abut one edge in the slit, and a stable mounting state without play is obtained, and at the same time, the torsion is obtained. Based on the deformation, the rigidity of the belt-shaped plate is enhanced, and the rigidity of the work as a support base can be increased. Therefore, the rigidity of the support base can be ensured, and the stable mounting state without backlash based on the elastic deformation due to the torsion and the strengthening of the rigidity as the strip-shaped plate are combined with the vibration of the processing machine itself, etc. Resonance phenomena and the like, which are likely to occur due to rattling of the band-shaped plate material, can be prevented.

The specific angle, width, depth, etc. of the slits formed in each mounting member are determined by taking into consideration the shape, thickness, elasticity conditions, type of work, etc. of the strip-shaped plate. The setting is made so as to ensure the required flatness as a surface. In this case, a plurality of mounting members with different angles, widths, depths, pitches between slits, etc. are prepared and replaced according to the case to cope with various forms related to band-shaped plate materials. It is possible to Further, if adjusting means for adjusting the angle, width, depth, etc. of these slits is provided on the mounting member itself, it is not necessary to change the mounting member, so that it is possible to cope more easily. In addition, the intervals between the mounting members need not always be constant. In order to more effectively suppress the resonance phenomenon due to the shape of the workpiece, etc., the intervals between the mounting members are set unequally to form a band. Change the torsional state of the plate,
It is free to increase or decrease the number of mounting members in three or more rows. In short, when the strip is twisted and inserted into the slit of each mounting member, its workability is good, and based on the elastic deformation caused by the torsion, the strip-shaped strip has a stable mounting state with no backlash and enhanced rigidity. Can be obtained as long as it is effective in suppressing the resonance phenomenon. In order to improve the flatness of the support surface by suppressing the unevenness of the support surface caused by the torsion of the strip, the change in the relative angle of the slit may be set small. Therefore, as long as a stable support state in the above-described slit and sufficient rigidity as a support base can be obtained, it is better to suppress the relative angle change to be small. The magnitude of the optimum angle change varies depending on the shape of the strip-shaped plate and the elastic condition, but may vary. However, in general, the angle is preferably set to be about 2 to 8 degrees around the vertical direction. If it is set, the unevenness appearing on the support surface is of such a degree that does not hinder practical use, and a good function as a support base can be obtained. If the mounting member is formed of brass or high carbon steel, it is possible to prevent the band-shaped plate piece from welding to the mounting member due to heating during processing.

In attaching the strip to the mounting member, one end of the strip is inserted into the slit of the mounting member at one end, and the slit of the adjacent mounting member is held while maintaining the state. While twisting according to the angle of
Mounting is possible only by sequentially inserting along the angle of each slit. As described above, in the present invention, it is possible to smoothly insert along the respective slits from one end to the other end while twisting the band-shaped plate piece to match the angle of the slit. Therefore, compared to the conventional case where the strips are inserted into each slit in the vertical direction while deforming the strip in a wavy shape as described above, the work of inserting into each slit becomes extremely simple, Can greatly improve the workability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings, in which mounting members are arranged such that slits formed in adjacent mounting members are alternately inclined in the opposite direction to the vertical direction. Will be described. 1 is a schematic perspective view showing the whole of the embodiment, FIG. 2 is an enlarged view of a main part showing a main part of a support portion of the work, and FIG. 3 is a longitudinal sectional view of FIG. In the drawing, reference numeral 1 denotes a work support, which is incorporated in a processing machine (not shown) and which is used as a general work support for supporting and processing a work on an upper portion thereof. In the present embodiment, three rows of mounting members 3 to 5 are provided in the inner space of the main body 2 of the work support table 1, and the slits 6 to 8 formed in a comb shape are alternately inclined in opposite directions. As shown in the main part enlarged view of FIG.
Are alternately twisted in the opposite direction to form a basic configuration as the work support table 1. In the present embodiment, convex portions and concave portions are alternately formed at a predetermined pitch at the upper ends of the band-shaped plate pieces 9 and 10, as described later. The projections are formed so as to be shifted by a half pitch so that the phases of the projections are opposite between the ten. The work supporting surface is formed by the convex portions formed on the upper end portions of a number of strip-shaped pieces 9, 10 alternately arranged and mounted on the mounting members 3 to 5. In the drawing, reference numeral 11 denotes a generally used work lifter, which is provided with a free ball bearing or the like at its tip and is provided so as to be able to undulate so as to protrude above the strips 9 and 10 when positioning the work. I have.

FIG. 4 is a partially enlarged view showing the band-shaped plate piece 9 in an enlarged manner, and FIG. 5 is a partially enlarged view showing the band-shaped plate piece 10 in an enlarged manner. As described above, these strip-shaped plate pieces 9 and 10 are made of elastically deformable plate material such as metal.
By alternately twisting and attaching to the attachment members 3 to 5, a stable attachment state without play and an increase in rigidity as a band-shaped plate piece are achieved based on the elastic deformation. As shown, the strips 9, 10
The convex portions 12 and the concave portions 13 are alternately formed at a predetermined pitch at the upper end of the. The concave portion 13 does not have a special function as a support base, and when the band-shaped plate pieces 9 and 10 are manufactured as described later, the convex portions 12 of the adjacent band-shaped plate pieces 9 and 10 are formed.
Is formed as a result of forming As is clear from the comparison between FIG. 4 and FIG.
The protrusions 12 are formed with a phase shift of half a pitch between each other. And when attaching to the attachment members 3-5, since the strip-shaped plate pieces 9 and 10 are arranged alternately, the convex parts 12 are more evenly distributed, and a good supporting surface is obtained. In the present embodiment, the strip-shaped plate pieces 9,
Although the case in which the protrusions 12 are separately formed and the protrusions 12 are shifted by a half pitch has been described as an example, if the shapes of the positioning portions and the like of the both ends with the main body 2 side are unified, the front and back can be inverted. Since the projections 12 can be set in a state of being shifted by a half pitch, it is also possible to use a common member for the strips 9 and 10.

FIG. 6 shows the mounting members 3 provided on both sides.

On the other hand, in the present embodiment, the mounting member 4 provided at the center portion is different from the mounting member 4 in that the width in the height direction is formed slightly smaller in relation to the mounting on the main body 2 side. However, as shown in FIG. 7, the slit 7 is formed in a state where the slit 7 is similarly inclined with respect to the vertical direction by the inclination angle α, and there is basically no difference. Therefore, the mounting members 3 to 5 can be shared by unifying the dimensions in the height direction. In this embodiment, the inclination angle α is approximately 4 degrees.

When the mounting members 3 to 5 are disposed on the main body 2 side, the mounting direction of the center mounting member 4 is reversed with respect to the mounting members 3 and 5 on both sides, and the slits 6 and 8 are 7
Are set so that they are inclined in the opposite directions to each other in the vertical direction. When attaching the strips 9 and 10 to these mounting members 3 to 5, one end of the strips 9 and 10 is attached to the slit 6 of the mounting member 3 as described above. Inserting along the inclination, while maintaining that state, then partially inserting the central portion of the strips 9 and 10 while twisting them in the opposite direction in accordance with the inclination direction of the slit 7 of the adjacent mounting member 4, Thereafter, it is inserted into the slit 8 of the mounting member 5 at the other end while being twisted in the opposite direction in accordance with the inclination direction thereof, and can be easily mounted by pushing the whole.

In the above embodiment, three rows of mounting members 3 to 5 are used as mounting members for the strips 9 and 10, but the strips 9 and 10 are alternately twisted. The number of columns can be arbitrarily selected as long as the array has three or more columns. Also, the recesses 13 of the strips 9 and 10
Alternatively, the shape can be freely changed, such as omitting the convex portion 12 and the concave portion 13. In the case of the present embodiment, the work supporting table 1 may be formed by inserting the strip-shaped plate pieces 9 and 10 alternately while twisting them in accordance with the slits of the mounting member that is alternately inclined.

It has features.

As described above, in the present invention, a strip-shaped plate is used as a main element constituting a work support table, and a plate can be used as a mounting member for the strip-shaped plate as in the above embodiment. Therefore, when using a laser processing machine as a processing machine, it is necessary to easily procure those strips and mounting members using a cutting program stored in advance in a processing control unit of the laser processing machine itself. can do. That is, in the case of the strips 9 and 10 of the above embodiment, a program for alternately cutting the strips 9 and 10 from the plate 14 as shown in FIG. If it is stored, the user can easily and efficiently produce the program by using the program. Similarly, in the case of the mounting members 3 to 5, by storing a program for cutting from the plate material 15 as shown in FIG.

[0015]

According to the present invention, the following effects can be obtained. (1) In attaching the strip-shaped plate, one end of the strip-shaped plate is inserted into the slit of the attachment member at one end, and the slit is sequentially adjusted to the angle of the slit of the adjacent attachment member while maintaining that state. While twisting, installation is possible only by inserting along each slit. Therefore, compared to the conventional case where the strip is inserted into each slit in the vertical direction while deforming it in a wavy shape, it is possible to insert it smoothly along the slit angle while twisting, making the installation work extremely simple. Therefore, workability at the time of attaching and replacing the strip can be greatly improved. (2) The rigidity of the strip is strengthened based on the elastic deformation due to the torsion, and the rigidity as the work support is easily secured, and there is no play in the slit due to the elastic force due to the torsional deformation. Along with the mounting state, it is possible to prevent a resonance phenomenon of the strip-shaped plate piece derived from the vibration of the processing machine itself. (3) If the strips are alternately twisted in the opposite direction, a wide support surface is formed while maintaining the flatness of the support surface of the work formed by the upper end of the strip. It is easy to do.
