Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a touscan used for centering a work mounted on a lathe (referring to a scribe of a work).

[0002]

[Prior art]

 Conventionally, when centering a work mounted on a lathe, a touscan is usually placed on the base or bed of the lathe (hereinafter, in principle, the base), and the flat portion of the upper surface of the base is used. It is a structure that centers the work while moving it.

Therefore, the bottom surface of the fixed stand of the Tohsukan is finished into a highly accurate flat surface, which allows stable centering.

Examples of documents that can be centered at a predetermined position by sliding on a surface plate, a base, or a base include, for example, Tohsuan of No. 55-7688, or No. 2-63986 of No. There is a scribing device.

Further, various documents can be cited as the centering of the work. For example, there is a centering jig of Jikkei 1-223747, a scribing jig of Jikkei 2-22230, and the like.

[0006]

[Problems to be solved by the device]

 However, for example, when centering a work mounted on a lathe, when carrying out centering work by placing a toscan on the base, the shape is not necessarily limited to the plane shape, and as shown in FIGS. In many cases, there is a mountain-shaped slide piece structure at each angle.

[0007] Therefore, it is not possible to stably mount the conventional fixed base on a toscan having a flat bottom surface, and thus it is difficult to perform accurate centering.

The above-mentioned technical document has a configuration in which a flat surface portion on a base is moved. For example, it is possible to place the flat surface portion on the flat base of the lathe and move along the flat surface portion of the base. However, it seems to be a technology different from the present invention.

That is, an object of the present invention is to provide a tohsucan which can be stably placed on a mountain-shaped slide piece and can be accurately and quickly centered.

[0010]

[Means for Solving the Problems]

 In the touscan according to the present invention, a V-shaped portion is formed on the fixed surface of the fixing base so that it can be fitted to the mountain-shaped slide piece, and the flat portion (horizontal bottom surface) of the fixing base is used. The following configuration is adopted for the purpose of making it possible to use it for the conventional centering or the base of the lathe in plan view.

That is, the tohscan equipped with a fixing base having a V-shaped portion on the bottom surface of the present invention has a pillar vertically installed along a groove of the pillar and a pillar vertically installed on the fixing base movable in the horizontal direction. A toe-scan, which comprises a movable scriber body and a screw for fixing the scriber body at an arbitrary angle in the vertical direction of the column, a flat surface portion and a flat portion on the bottom surface of the fixing base. The V-shaped portion is provided on the bottom surface, which is characterized in that the V-shaped portion is provided.

[0012]

[Action]

 For a mountain-shaped slide piece such as a lathe, fit the V-shaped part on the bottom surface of the fixed base (hereinafter referred to as the fitted state) and adjust the position of the scribing needle and the cutting edge of the scribing needle body. Then, after fixing the scribing needle main body to the column, by fixing or moving the toescan, the centering line of a predetermined height can be surely and easily centered at a predetermined position of the work. .

Therefore, even if the work is long, no error occurs in the centering position at each predetermined position.

When the workpiece is rotated while trying to center it at another position of the workpiece with the fixed table placed on the mountain-shaped slide piece, the workpiece has irregularities. Even if the mountain-shaped slide piece is accidentally misaligned from the fixed base and the entire toescan is shaken, if the original mated state is restored, the mountain-shaped slide piece and the fixed base will be properly aligned. A secure fitting position is secured, which allows accurate centering work at this position.
