Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a workpiece processing workbench device used for processing precision workpieces having relatively small dimensions.

(Prior Art) When shaping or polishing a dental workpiece such as a denture or a precision workpiece such as jewelry, a processing workbench device is used which is provided with a portion on which the workpiece is placed. As one of such processing workbench devices, the Federal Republic of Germany Utility Model No.
7736347 is known, which includes a work table and uses the top surface of the table as a processing work plane. Such a processing work plane is subjected to various optical influences depending on objects placed in the room in which it is set, or the shape and color of the walls and windows of the room.

(Problems to be Solved by the Invention) When the processing workbench device as described above is used, not only does interference reflected light occur when the processing work surface is artificially illuminated, but also artificial illumination is not provided. Occasionally, workers performing machining work on the machining work plane are particularly required to perform work that requires accurate observation of the workpiece, for example, where subtle differences in color may be a problem, as is well known. There is an inconvenience in that the work in the process of manufacturing teeth or dentures is hindered by the above-mentioned optical influences.

In view of this point, the present invention provides that the workpiece to be processed, such as a dental precision workpiece, placed thereon is
It is an object of the present invention to provide a workpiece processing workbench apparatus which is substantially free from undesired optical influences from the surrounding environment.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the workpiece processing workbench device according to the present invention includes a workpiece mounting section disposed on the work plane forming section, and a workpiece mounting section. The surface facing the mounting part has a white or gray tone,
An artificial background forming member that forms a background for the workpiece placed on the workpiece mounting portion is disposed on the work plane forming portion while being supported by a supporting member, and the supporting member is configured to be moved so as to selectively take a position that is effective for forming a background with respect to the workpiece and a position that is not effective.

By adopting the configuration including the artificial background forming member in this way, the workpiece placed on the workpiece placement section is placed in a substantially optically neutral environment for the operator. This significantly reduces optical interference to the operator from the surrounding environment.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an example of a workpiece processing workbench apparatus according to the present invention. This example forms a processing workbench device 3 used for processing a dental workpiece 1, and has a working plane forming part 9. Workpiece to be done 1
An artificial background forming member 2 is provided to clarify the color tone or color tone difference. This artificial background forming member 2 is intended to form an optically neutral environment in the processing workbench device 3. Therefore, at least the surface of the artificial background forming member 2 facing the position where the workpiece 1 to be processed is arranged has a daylight color tone. That is,
The color tone of the artificial background forming member 2 is white or gray, for example, in the range from light gray to medium density gray.

The artificial background forming member 2 is basically configured to form a wall 4, and preferably forms a flat surface as shown in FIGS. 2 and 8. However, depending on the state of external light on the processing workbench device 3, the
As shown in the drawings and FIG. 7, the artificial background forming member 2 forms a convex surface 5 that projects in a direction away from the position where the workpiece 1 to be processed is placed. Such a convex surface 5 is the third one when viewed from above.
A V-shape, as in the case of Figure 6, or a fourth
It forms a U-shape as shown in Figures and Figure 7.

Further, the artificial background forming member 2 is provided with an edge portion 6 extending toward the position where the workpiece 1 to be processed is placed, as shown in FIGS. 5 to 7. Furthermore, as shown in FIG. 9, it has a lower end 7 extending toward the position where the workpiece 1 to be machined is placed. In the case of the edge portion 6 and lower end portion 7 shown in FIGS. 5 and 9, respectively, the artificial background forming member 2 is provided with a bent curvature portion 8 at the end thereof.

Advantageously, such an artificial background forming member 2 can be moved from an effective position in which it acts effectively to an ineffective position in which it does not act. Therefore, the wall 4 formed by the artificial background forming member 2 is foldable,
It may be slidable, tiltable or, as shown, rollable, for example in the form of a roll-up blind. In FIGS. 1 and 8, the artificial background forming member 2, which is rotated about the upper horizontal axis 29 and assumes an inclined position, is shown in broken lines.

The above-mentioned protection plate 20 is positioned to guide dust to the suction port 21 and to protect the face of the worker who performs processing work on each processing workbench device from the dust. The dust is, for example, shavings generated by sanding, grinding ducts, and the like. The protection plate 20 can be moved from a position close to the suction device 22 that guides dust to the suction port 21 to be separated from the suction device 22, and therefore can be rotated around a rotation axis 23 extending in the horizontal direction. has been done.

The suction device 22 is provided on the work table 11 to which the arm rest 24 is attached.
are arranged on both sides of the suction device 22. The suction device 22 is provided with a workpiece mounting table 25 on which the workpiece 1 to be machined is placed, and this workpiece mounting table 25 is arranged above the work plane forming section 9 .
