Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a processing table skid, and more particularly to a processing table skid that can be easily manufactured and replaced in a laser processing machine in a short time.
[0002]
[Prior art]
Conventionally, in a laser processing machine, as shown in FIG. 5, a skid 51 is arranged on a processing table 50, and the work W is supported by the skid 51.
[0003]
The skid 51 is formed of a sheet metal having a predetermined plate thickness, and a portion in contact with the workpiece W is pointed like a triangle or a needle as shown in the figure, so that the workpiece W and the skid 51 are not easily welded during laser processing. It has become a shape.
[0004]
[Problems to be solved by the invention]
[0005]
Since the skid 51 (FIG. 5) is consumed during use, the operator replaces the skid 51 by newly manufacturing the skid 51 with a laser processing machine.
[0006]
However, the skid 51 has a part that is frequently used within the processing range, and only a part is often consumed.
[0007]
For example, normally, regardless of the size of the workpiece W, the vicinity of X = 0 and Y = 0 on the machining program is frequently used, and the consumption in the vicinity of X = 0 and Y = 0 is significant (FIG. 1). R region).
[0008]
However, conventionally, even if a part of the skid 51 is consumed, the entire part including the consumed part is manufactured by a laser processing machine, and the manufactured skid is replaced with an old one.
[0009]
Therefore, producing a large number of skids with tens to hundreds including consumable parts is a heavy burden and takes time, and it is not easy and time consuming to replace the manufactured skids. Extremely long.
[0010]
As a result, the processing time of the original workpiece W is limited for manufacturing and exchanging the skid, resulting in a decrease in processing efficiency.
[0011]
An object of the present invention is to provide a processing table skid that can be easily manufactured and replaced in a laser processing machine in a short time.
[0012]
[Means for Solving the Problems]
In order to solve the above problems, the present invention, as shown in FIG.
The support piece 7 includes a support piece 7 that supports the workpiece W, a substrate 4 that contacts the support piece 7, and sandwiching plates 5 and 6 that hold the support piece 7 by sandwiching the substrate 4 from both sides. A technical means called a processing table skid characterized in that the piece 7 is detachable and replaceable.
[0013]
According to the configuration of the present invention described above, the shape of the support piece 7 which is a consumable item (FIG. 4A) can be manufactured easily and in a short time using a shearing machine or the like, for example, by making it a simple square. In addition, since the square support piece 7 'is replaced with a new support piece 7 only when the square support piece 7' is not reusable (the right support piece 7 'in FIG. 4B), it can be exchanged easily and in a short time.
[0014]
Therefore, it is possible to provide a processing table skid that can be easily manufactured and replaced in a laser processing machine in a short time.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described with reference to the accompanying drawings by embodiments.

[0023]
Since the support piece 7 is square, it has a simple shape and can be manufactured easily and in a short time by a shearing machine or the like. Moreover, since the support piece 7 can be easily processed using materials such as copper and brass that are optimal as work support pieces, the production is also simplified.
[0024]
A large number of such square support pieces 7 are manufactured in advance (FIG. 4A) and stored in a rack or the like, and the support piece 7 ′ is worn out and needs to be replaced (FIG. 4 ( B) Right side) Prepare.
[0025]
Therefore, since only the support piece 7 which is a consumable part of the processing table skid 2 can be easily manufactured using a shearing machine or the like, according to the present invention, the processing table skid 2 can be manufactured easily and in a short time. There is an effect.
[0026]
The support piece 7 has a square shape as described above, and its two opposite vertices C1 and C2 (FIG. 3A) are arranged on the vertical line V, and the other two opposite vertices C3 and C4. Are arranged on a horizontal line H, respectively.
[0027]
On the other hand, the substrate 4 is formed in a rectangular shape that is long in the Y-axis direction (FIGS. 1, 2, and 3).
[0028]
The substrate 4 is formed with a notch 4A (FIG. 3A). The notch 4A corresponds to the lower half 7B of the square support piece 7, and the whole has two sides. It has the shape of a right isosceles triangle with a length of a.
[0029]
The vertices D3 and D4 above the notch 4A are at vertices C3 and C4 on the horizontal line H of the support piece 7 (FIG. 3A), and the vertex D2 below the notch 4A is perpendicular to the support piece 7. Each corresponds to the lower vertex C2 on the line V.
[0030]
With this configuration, each side of the lower half 7B of the support piece 7 is in close contact with each side of the cutout portion 4A, and the support piece 7 is placed on the cutout portion 4A of the substrate 4 through the lower half 7B. The upper half 7A protrudes above the substrate 4 (FIG. 3B), and a plurality of such support pieces 7 are arranged in the Y-axis direction as described above (FIG. 1). , FIG. 2).
[0031]
Also, the substrate 4 (FIG. 2) is formed with screw holes 4B, which correspond to the screw holes 5B and 6B formed in the sandwich plates 5 and 6, respectively.
[0032]
The sandwiching plates 5 and 6 (FIG. 2) have the same Y-axis direction as the Y-axis direction of the substrate 4, and the height is slightly larger than the height of the substrate 4 (FIG. 4B).
[0033]
With this configuration, the substrate 4 is sandwiched by the sandwich plates 5 and 6 on both sides thereof, and the substrate 4 and the sandwich plates 5 and 6 are fixed by the bolts 8 (FIGS. 1, 2, and 3 ( B)).
[0034]
Accordingly, each support piece 7 placed in the cutout portion 4A of the substrate 4 (FIG. 3B) is brought into contact with and caught by the sandwich plates 5 and 6 and does not swing even when the workpiece W is supported. It is designed to be firmly fixed.
[0035]
The support piece 7, the substrate 4, and the sandwiching plates 5 and 6 constitute an assembly (FIG. 1), and the assembly is inserted between the left frame 3A and the right frame 3B of the frame 3. The both sides of the assembly are joined to the left frame 3A and the right frame 3B by welding or the like.
[0036]
As a result, as described above, a plurality of assemblies of the support piece 7, the substrate 4, and the sandwich plates 5 and 6 (FIG. 1) are attached in the X-axis direction.
[0037]
The upper half 7A of the support piece 7 protruding from the substrate 4 (FIGS. 1 and 2) is exposed from the assembly and has a sharp triangular shape when viewed from the outside. W is supported, and as described above, the workpiece W and the processing table skid 2 are difficult to weld during laser processing.
[0038]
Then, if the machining head 9 moves to a predetermined position of the workpiece W supported by the support piece 7 and irradiates a laser beam from the machining head 9, as described above, the workpiece W on the machining table skid 2 is applied to the workpiece W. Predetermined laser processing can be performed.
[0039]
In this case, when the work table skid 2 is consumed while the workpiece W on the work table skid 2 is laser processed, the following is performed.
[0040]
That is, as in the case of the left support piece 7 in FIG. 4B, for example, when only one vertex C1 ′ is consumed and the other vertexes C2 to C4 are reusable, the bolt 8 is first loosened and supported. The piece 7 is released (the left figure of FIG.4 (C)).
[0041]
Thereafter, by rotating the support piece 7 by 90 ° counterclockwise, for example, the consumed vertex C1 ′ is arranged on the cutout portion 4A side, and the non-consumed vertex C4 is arranged on the upper side (right side of FIG. 4C). Figure).
[0042]
If the bolt 8 is closed in this state (the right figure in FIG. 4C), the support piece 7 on the substrate 4 is again firmly locked and fixed by the sandwich plates 5 and 6, and the workpiece W is supported by the vertex C4. it can.
[0043]
Thereby, the support piece 7 can be reused.
[0044]
If the four apexes C1 'to C4' are all worn out and cannot be reused like the right support piece 7 'in FIG. 4B, the bolt 8 is loosened to release the support piece 7'. Then, the support piece 7 ′ is removed from the notch 4 A of the substrate 4.
[0045]
In this state, a new support piece 7 stored in a rack or the like is placed in the notch 4A of the substrate 4 and the bolt 8 is closed, so that the new support piece 7 is firmly locked by the sandwich plates 5 and 6. Fix it.
[0046]
Thereby, the support piece 7 was replaced | exchanged.
[0047]
As described above, according to the present invention, only when all the vertices C1 ′ to C4 ′ of the support piece 7 ′ are consumed (the right side in FIG. 4B), the new support piece 7 may be replaced. Even when a part is consumed, the replacement is extremely easy and can be performed in a short time compared to replacing the whole.
[0048]
The operation of the present invention having the above configuration will be described below.
[0049]
(1) Production of the support piece 7
[0050]
First, before processing the workpiece W (FIG. 1), a large number of support pieces 7 are manufactured in advance using a shearing machine (FIG. 4A) and stored in a rack or the like.
[0051]
In this case, as described above, since the support piece 7 is a square (FIG. 4A), the shape is simple, and the support piece 7 can be manufactured easily and in a short time by a shearing machine or the like.
[0052]
Therefore, since only the support piece 7 which is a consumable part of the processing table skid 2 can be easily manufactured using a shearing machine or the like, according to the present invention, the processing table skid 2 can be manufactured easily and in a short time. There is an effect.
[0053]
(2) Operation when the support piece 7 is reusable.
[0054]
As described above, in the processing table skid 2 (FIG. 1), for example, a portion of the region R is frequently used, and only a portion of the region R is often consumed.
[0055]
The region R is consumed, but only one vertex C1 ′ of the support piece 7 is consumed (the left support piece 7 in FIG. 4B).
[0056]
In this case, since the other vertices C2 to C4 can be reused, the bolt 8 is first loosened to release the support piece 7 (the left figure in FIG. 4C).
[0057]
Next, the support piece 7 is rotated 90 ° counterclockwise (right side of FIG. 4C), and the worn vertex C1 ′ is disposed on the cutout portion 4A side, and the non-consumed vertex C4 is disposed on the upper side. To do.
[0058]
In this state, the bolt 8 is closed (the right figure in FIG. 4C), and the support piece 7 on the substrate 4 is firmly locked and fixed by the sandwich plates 5 and 6, so that the apex C4 of the support piece 7 Support and reuse the workpiece W. .
[0059]
【The invention's effect】
As described above, according to the present invention, the processing table skid includes a support piece for supporting a workpiece, a substrate with which the support piece is brought into contact, and a holding plate for holding the support piece by holding the substrate from both sides. By configuring the support piece as a consumable part, for example, by using a simple square, the support piece can be easily and quickly removed using a shearing machine. The replacement can be performed easily and in a short time because it can be manufactured and replaced only when the square support piece is not reusable.
[0060]
For this reason, in a laser processing machine, there exists an effect of providing the process table skid which can be manufactured and replaced | exchanged easily and for a short time.
[0061]
In addition, optimal production is performed by changing the material of the support piece, which is a consumable part, according to the workpiece to be processed. For example, if you do not want to scratch the work, produce a support piece made of copper, etc. In addition, since the support piece can be replaced easily and in a short time, the support piece can be frequently exchanged, so that an accurate pass line can be maintained, so that a highly accurate workpiece can be processed. There is also.
