[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiving piece for supporting a work positioned at an assembling position.

[0002]

2. Description of the Related Art In order to assemble a workpiece such as a part,
The work is positioned and supported by the receiving piece.

[0003]

The receiving surface of this receiving piece is worn due to repeated use, and proper quality cannot be ensured. For this purpose, the worn work receiving surface is overlaid to return to the initial state. However, since the amount of wear is visually checked and overlaid, there has been a problem that the accuracy may vary.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems and to provide a work machining receiving piece capable of returning to a work receiving surface in a highly accurate initial state.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the gist of the present invention is to provide a receiving piece having a work receiving surface and placed on the piece main body, An adjustment plate having a constant thickness interposed between the work piece and a scale line is provided on the side surface of the receiving piece at the same size interval as the thickness dimension of the adjustment plate from the work receiving surface;
A work receiving surface wear amount detecting means for detecting the wear amount of the scale line at one pitch of the work receiving surface is provided.

[0006]

According to the above construction, when the work receiving surface of the receiving piece is worn by one pitch of the scale line, the work receiving surface wear amount detecting means detects and displays the portion, and the portion remaining on the work receiving surface is deleted by one pitch of the scale line. The work receiving surface of the receiving piece is returned to the initial state by interposing the adjusting plate having the thickness corresponding to one pitch of the deleted scale line between the piece main body and the receiving piece. It is to let.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, reference numeral 1 denotes a bridge main body, which is fixed on a base plate 4. Reference numeral 2 denotes a receiving piece placed on the piece main body 1, and the upper surface thereof is a work receiving surface 2.
a is formed.

Reference numeral 3 denotes an adjusting plate interposed between the block main body 1 and the receiving block 2, and has a constant thickness. Although the intervening structure of the adjustment plate 3 is not shown, a projection such as a pin is provided on the upper surface of the adjustment plate 3 to protrude therefrom.
Protrusions are provided on the lower surface to fit the protrusions, protrusions are provided on the upper surface of the piece main body 1, and recesses are provided on the lower surface of the receiving piece 2 so that they are fixedly interposed at fixed positions by the concave and convex fitting. Has become.

A work receiving surface 2a is provided on a side surface of the receiving piece 2.
Thus, graduation lines 4 are provided by marking or the like at the same interval as the thickness of the adjustment plate 3.

Further, there is provided a work receiving surface wear amount detecting means for detecting a one-pitch wear amount of the graduation line 4 of the work receiving surface 2. An example of the structure of the work receiving surface wear amount detecting means will be described with reference to FIG. The detection bar 5 penetrates through the base plate 4, the piece main body 1, the adjustment plate 3, and the receiving piece 2,
The upper end is urged by a spring 6 so as to always protrude to the receiving surface 2 a of the receiving piece 2, and can be moved up and down.

A conductive piece 7 is provided at the lower end of the detection bar 5, and electrical contacts 8 with which the conductive piece 7 contacts are arranged at regular intervals. The fixed distance between the electric contact 8 and the conductive piece 7 is equivalent to one pitch of the scale line 4.
The electrical contact 8 is connected to a central processing unit 9 via a harness, and a detection display panel 10 is connected to the central processing unit 9. In addition, as the work receiving surface wear amount detecting means, a proximity switch or an optical fiber can be used in addition to the above structure.

Since the present invention has the structure as described above, when the initial work receiving surface 2a of the receiving piece 2 is worn by one pitch of the scale line 4, as shown in FIG. The detection bar 5 is pushed down by the work W supported by 2b, and the conductive piece 7 comes into contact with the electric contact 8, so that the central processing unit 9 displays the wear on the detection display 10.

As a result, the remaining portion S of the initial work receiving surface 2a is cut to the scale line 4 of the worn work receiving surface 2b, and the worn work receiving surface 2b is corrected to a flat surface. Thereafter, the worn work receiving surface 2b is precisely returned to the initial state of the work receiving surface 2a by interposing the adjusting plate 3 between the frame main body 1 and the receiving piece 2.

For example, as shown in FIG.
When the pitch interval is 0.5 mm, the thickness of the adjustment plate 5 is also 0.5 mm. Therefore, the receiving surface 2b that has been worn down by 0.5 mm and corrected to a flat surface is corrected by 0.5 mm by the intervention of the adjusting plate 5, and the corrected work receiving surface 2b returns to the initial state of the work receiving surface 2a. is there.

[0015]

As described above, according to the present invention, the receiving piece having the work receiving surface is placed on the piece main body via the adjusting plate having a constant thickness, and the side of the receiving piece is adjusted from the work receiving surface. Since the scale line is provided at the same interval as the thickness of the plate and the wear amount detecting means for detecting the wear amount of the scale line 1 pitch of the work receiving surface is provided, the work receiving surface of the receiving piece is provided. In addition to being able to accurately detect the amount of wear, and instead of correcting the amount of wear as in the past, the wear surface is corrected to a flat surface and compensated by the amount of wear equivalent to the amount of wear. It is possible to return to the workpiece receiving surface state with high precision, and the processing accuracy of the product is improved.
