JP 2000-218530 A (FIG. 1) Japanese Patent Laid-Open No. 5-77164 (FIG. 1)

  The "surface grinder" of "Patent Document 1" in "Japanese Patent Laid-Open No. 2000-218530" and "Patent Document 2" in "Japanese Patent Laid-Open No. 5-77164" have a short workpiece. There is a relatively long table. In addition, a dresser is arranged on the table, and there are some similarities to the present invention described later, but the table is not separable, its assembly is not good, and it has a general structure. is there.

In the case of a surface grinder using a long table, it is generally difficult to finish the flatness of the upper surface of a long workpiece with high accuracy, and heat is transferred to the entire surface to improve the flatness. There is also a problem of lowering. In general, since the moving mechanism for moving the table is disposed on the lower surface side of the table, it is difficult to attach the moving mechanism to the lower surface of the table. There is a problem that becomes difficult.
Further, even if the table is separated, there is a problem that it is difficult to hold the upper surface of the table with high accuracy depending on the connection tool, and it is necessary to give special consideration to the connection tool.

The present invention has been invented in view of the above circumstances, and provides a processing apparatus having a separation long table that can process a long workpiece with high accuracy, has good assemblability, and good table mobility. For the purpose.

In order to achieve the above object, the present invention provides a processing apparatus for processing a long workpiece (200) , wherein the apparatus is equipped with the workpiece (200) . the long table (1), and a moving mechanism for moving the said long scale table (1), and a processing means located on the fixed side of the apparatus, the long table (1), said In the longitudinal direction of the long table (1), the table (1A) and the table (1B) are separated into two, and the two tables (1A) and the table (1B) are connected via a flexible connector. characterized in that it is connected.

The invention of claim 2 is characterized in that the moving mechanism is a linear motor provided on the lower surface of one separated table (1A) .

  According to a third aspect of the present invention, the processing apparatus is a surface grinder, and a dresser is disposed on the table.

  According to the processing apparatus having the separation long table of the first aspect of the present invention, the processing apparatus includes a table on which a workpiece is mounted, the moving mechanism portion, and processing means provided on the stationary side of the apparatus. Especially, since the table is a separation type and the separated table is connected by a flexible connector, there is no deviation in flatness due to heat transfer of the table, the table can be easily reversed, and high precision processing and assembly It is possible to improve the performance.

  Moreover, according to the processing apparatus having the separation long table according to claim 2 of the present invention, the movement mechanism portion is compact by adopting the linear motor disposed on one of the separated tables as the movement mechanism portion. In addition, the movement can be facilitated and the cost can be reduced.

  Further, according to the processing apparatus having the separation long table of claim 3 of the present invention, a surface grinder capable of high-precision surface processing of a workpiece is applied as the processing apparatus, and the scope of the invention is wide and separated. By attaching a dresser to the table, the attachment can be facilitated and the use efficiency can be improved.

[Example]
Embodiments of a processing apparatus having a separation long table according to the present invention will be described below in detail with reference to the drawings.
In the following description, a surface grinder that is considered to be most suitable as the processing apparatus of the present invention will be described, but the present invention is not limited to this and is naturally applicable to other processing apparatuses.

1 to 4 show a schematic structure of an example of a surface grinding machine 100 to which the present invention is applied. The surface grinding machine 100 is roughly divided into a long table 1 on which a workpiece 200 is mounted, a base table 2, a guide base 3 mounted on the base table 2 to guide the long table 1, a base table 2, From the linear motor 4 that is one of the moving mechanism units arranged between the long table 1, the grindstone table 5 that is one of the processing means placed on the base table 2, the dresser 6, and the like. Become. Incidentally, the workpiece 200 in this embodiment ing from those long.

Since the long table 1 long, ing from the table 1A and table 1B in the long scale table 1 is 2 separated as shown in FIGS. The table 1A is shorter than the table 1B, and the linear motor 4 is provided on the lower surface of the table 1A as shown in FIGS. The table 1A and the table 1B are arranged with a gap, and a flexible connector 7 is interposed between them. Although the structure of the flexible connector 7 is not described here, the table 1A and the table 1B The structure of absorbing relative displacement between is applied. The workpiece 200 is mounted on the upper surface of the table 1B.

  The base table 2 is placed on the ground 8, and a rigid flat plate block is used.

As shown in FIG. 4, the guide base 3 includes a guide block 3A placed on the base table 2 and a guide rail 3B fixed to the lower surface of the long table 1. However, the guide base 3 is not limited to this. .

  As shown in FIG. 4, the linear motor 4 is composed of a movable slider 4A attached to the lower surface of the table 1A and a magnetic body 4B fixed on the base base 2, but it is of course not limited to this structure.

  In this embodiment, the grindstone base 5 is composed of a grindstone body in a surface grinder. Of course, the grindstone body is of various structures, but in this embodiment, as shown in FIGS. 2 and 3, the apparatus body 5A is placed on the base stand 2 and moved in the vertical and longitudinal directions. And a grindstone 5B that is rotatably supported. In addition, about the detailed structure, since it is a general structure, description is abbreviate | omitted here.

  There are various types of dressers 6, and the description of the structure is omitted here. In this embodiment, the dresser 6A placed on the table 1A and the dresser 6B placed on the table 1B are taken as an example. Can be mentioned. Since dressing from each direction is necessary depending on the shape of the grindstone 5B, a plurality (two in this embodiment) of dressers 6A and 6B are provided. In addition, since each dresser 6A and 6B is mounted on the separate tables 1A and 1B, the installation is easy and the improvement of assembly property can be aimed at.

With the above structure, by operating the linear motor 4, the long table 1 moves in the horizontal direction, and the workpiece 200 can be ground with high precision by the dressed grindstone 5B. Although the movable slider 4A of the linear motor 4 is provided on the lower surface of the table 1A, the table 1A is made of a short one, the reversal is easy, and the movable slider 4A can be easily and accurately attached. . Further, since the long table 1 is separated into the table 1A and the table 1B, there is little heat transfer, and the accuracy such as flatness of the long table 1 can be maintained with high accuracy. Further, the displacement of the table 1A and the table 1B is absorbed by the flexible connector 7, and the flatness of the long table 1 can be maintained with high accuracy.
As described above, planar processing of the long workpiece 200 can be performed with high accuracy.

  The present invention comprises the contents of the above description, but is not limited to the above description contents, and those of the same technical category are of course applied.

  Although the present invention has been described with respect to the surface grinding machine as the processing apparatus, it can be applied to all processing apparatuses using a long table, and its use range is extremely wide.
