Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a receiving piece for supporting a work positioned at an assembly processing position.

[0002]

[Prior Art]

 In order to assemble and process the work such as parts, the work is positioned and supported by the receiving piece.

[0003]

[Problems to be solved by the device]

 The receiving surface of this receiving piece is worn by repeated use, and proper quality cannot be ensured. Therefore, the worn work receiving surface is piled up and returned to the initial state. However, since the wear amount is visually checked and built up, there is a problem that the accuracy varies.

An object of the present invention is to solve the above-mentioned problems of the related art and to provide a work machining receiving piece capable of returning to a highly accurate initial state work receiving surface.

[0005]

[Means for Solving the Problems]

 The gist of the present invention for achieving the above object is to provide a receiving piece having a work receiving surface and placed on the piece body, and a fixed piece interposed between the piece body and the receiving piece. An adjustment plate having a thickness dimension is provided, and a scale line is formed on the side surface of the receiving piece from the work receiving surface at the same size intervals as the thickness dimension of the adjustment plate, and the wear amount of one scale line of the scale receiving surface is detected. It is equipped with a means for detecting the amount of wear of the workpiece receiving surface.

[0006]

[Action]

 With the above configuration, when the work receiving surface of the receiving piece is worn by one pitch of the scale line, it is detected and displayed by the work receiving surface wear amount detecting means, 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 providing a flat work receiving surface and an adjustment plate having a thickness dimension corresponding to one pitch of the deleted scale line interposed between the piece body and the receiving piece. It is a thing.

【Example】

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

Reference numeral 3 is an adjusting plate interposed between the piece body 1 and the receiving piece 2, and its thickness has a constant dimension. Although not shown in the drawing, the interposition structure of the adjusting plate 3 is such that a protrusion such as a pin is provided on the upper surface of the adjusting plate 3 and a concave portion into which the protrusion is fitted is provided on the lower surface. Is provided with a projection, and a recess is provided on the lower surface of the receiving piece 2 so as to be fixedly intervened at a fixed position by fitting the projection and the depression.

Scale lines 4 are provided on the side surface of the receiving piece 2 from the work receiving surface 2 a at the same size intervals as the thickness of the adjusting plate 3 by marking or the like.

Further, there is provided a work receiving surface wear amount detecting means for detecting a one pitch wear amount of the scale line 4 on the work receiving surface 2. An example of the structure of this 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 body 1, the adjustment plate 3 and the receiving piece 2, and is urged by a spring 6 so that the upper end thereof always projects to the receiving surface 2a of the receiving piece 2 so that it can be moved up and down. ing.

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 constant distance between the electrical contact 8 and the conductive piece 7 corresponds to one pitch of the scale line 4. The electric 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 to the above structure, a proximity switch or an optical fiber can be used as the work receiving surface wear amount detecting means.

Since the present invention has the above-described structure, as shown in FIG. 3, when the initial work receiving surface 2a of the receiving piece 2 is worn by one pitch of the scale line 4, the worn work receiving surface The detection bar 5 is pushed down by the work W supported by 2b, the conductive piece 7 comes into contact with the electrical contact 8, and the central processing unit 9 displays the wear on the detection display 10.

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

For example, as shown in FIG. 3, when the one pitch interval of the scale lines 4 is 0.5 mm, the thickness of the adjusting plate 5 is also 0.5 mm. Therefore, the receiving surface 2b, which has been worn by 0.5 mm and corrected to be flat, is corrected by 0.5 mm by the interposition of the adjusting plate 5, and the corrected work receiving surface 2b returns to the initial state of the work receiving surface 2a. It is.

[0015]

[Effect of the device]

 As described above, according to the present invention, the receiving piece having the work receiving surface on the piece body is placed through the adjusting plate having a constant thickness, and the thickness of the adjusting plate is adjusted from the work receiving surface to the side surface of the receiving piece. The wear amount of the work receiving surface of the receiving piece is provided because the work receiving surface wear amount detecting means for detecting the wear amount of the one pitch line of the scale receiving line on the work receiving surface Can be accurately detected, and the wear amount is not corrected by overlaying as in the past, but the wear surface is corrected to a flat surface and the wear amount equivalent amount is compensated by interposing an adjustment plate. It is possible to return to the receiving surface state with high accuracy, improving the processing accuracy of the product.
