[Prior art]

 Conventionally, for example, in the design work in the development of automobiles and the like, a stereoscopic scale model is created from a planar drawing such as an idea sketch, and the image feeling is confirmed by a three-dimensional solid.

In this scale model, coordinates of main points are usually plotted in a grid on a clay or the like by a model production diagram created based on an idea sketch or the like, and each plot point is connected by a smooth curved surface. In addition to the cutting work, each face was modified to represent the model outline.

In the embodiment, three types of attachments are prepared for each application, including an attachment 36 for measurement / scribing, an attachment 37 for cutting, an electric drill 38 for rotary cutting. The attachment 36 has a round bar member whose tip is formed in a needle shape, and is formed so as to abut on a measured point of the three-dimensional solid 60 or draw a marking line on the surface thereof. The attachment 37 is formed such that the tip end portion of the round bar member is formed in a horizontal single-edged blade shape, and abuts on a processing point of the three-dimensional solid 60 to perform cutting.

Has been done.

The drawing unit 40 is mainly composed of a writing instrument 41, an arm 43 that supports the writing instrument 41, and a bracket 47 that supports the arm 43 swingably. The writing instrument 41 has a pencil lead protruding and attached at the center of the lower end, and a reference point 42 is engraved at the center of the upper end. The writing tool 41 is attached to the tip of the arm 43, and the base end of the arm 43 is swingably supported by a bracket 47 by a shaft 46 so that the writing tool 41 is lowered by its own weight. Reference numeral 45 is a set screw for fixing the writing instrument 41. The drawing unit 40 is fixed to the female screw 8 of the base 5 with a fixing screw 48, and is attached to the base 5 of the multifunction device 1.

Next, the operation of the compound device 1 configured as described above will be described.

First, when the three-dimensional solid 60 is manufactured, a model material such as clay corresponding to the preparation of the three-dimensional solid 60 is prepared, and the coordinate plate 50 larger than the plane size of the three-dimensional solid 60 is prepared.

As shown in FIG. 8, for example, the coordinate plate 50 has an L coordinate scale 51 in the lengthwise direction and a W coordinate scale 52 in the widthwise direction at predetermined intervals, and a three-dimensional solid 60 at a predetermined position. A positioning hole 53 is formed to define the relative position to the position.

Then, the model material is provided with a projection 61 that fits into the positioning hole 53, and the projection 61 is fitted into the positioning hole 53 to fix the relative position of the two, and the model material is placed on the standard plate 50. Place on. Further, an attachment 37 is attached to the compound device 1 (when the electric drill 38 is used, it is attached via the attachment holder 31 instead of the attachment holder 27), and on a plane 70 such as a work desk on which the coordinate plate 50 is placed. Place the compounder 1 on and set 0 of the compounder 1.

In the 0 set of the multi-function device 1, the arm slide guide 15 and the arm 25 are operated to align the tip of the cutting blade of the attachment 37 with the O reference point 7 (see the chain double-dashed line in FIG. 9). This zero set fine adjustment is performed by the attachment angle of the attachment 37 in the attachment holder 27 and the advance / retreat. At this time, the Y reference line 21 is adjusted to the 0 scale of the Y-axis scale 26, and the Z reference line 17 is adjusted to the thickness equivalent value of the X-axis scale 6 on the Z-axis scale 12 (for example, 3 m / m). .

Next, the X-axis scale 6 of the compound device 1 is brought into close contact with the edge of the coordinate plate 50, and the O 2 reference point 7 is set to an arbitrary coordinate of the L coordinate scale 51, for example.

Then, by operating the arm slide guide 15 and the arm 25, the tip of the attachment 37 is brought into contact with the three-dimensional solid 60. At this time, with respect to the tip position of the attachment 37, the coordinates in the height direction and the width direction of the three-dimensional solid 60 at arbitrary coordinates of the L coordinate 51 can be read by the Z axis scale 12 and the Y axis scale 26, respectively. It is possible to perform coordinate setting and cutting at the same time. The compound device 1 is moved in the length direction of the three-dimensional solid 60 by moving the O reference point 7 with respect to the L coordinate scale 51 or moving a specific point of the L coordinate scale 51 with respect to the X axis scale 6. Then, the coordinate in the length direction can be changed.

As described above, the coordinates of the main points can be accurately cut without forming a coordinate grid on the model material. In this case, it is desirable that the drawing unit 40 be removed from the base 5.

The measurement of the three-dimensional solid 60 is performed by attaching the attachment 36 to the attachment holder 27 instead of the attachment 37 described above.

In this case, the reading of each coordinate by the 0 set and the use of the coordinate plate 50, and the involvement of the attachment 36 in contact with the three-dimensional solid 60 is the same as in the case of the above manufacturing, and the description thereof will be omitted. As a result, each coordinate can be measured without creating a coordinate grid on the three-dimensional solid 60.

Next, the drawing of the three-dimensional solid 60 will be described.

The attachment 36 is attached to the compound device 1, and the drawing unit 40 is attached to the base 5. When drawing a contour diagram in the front-back direction, the three-dimensional solid 60 is fixed to the holder 55 in a posture in which the front-rear cross-section is projected on the plane 70 (see FIG. 10), and the Place it on the plane 70. A drawing sheet 75 is placed and fixed on the flat surface 70.

First, in the compound machine 1, 0 set for drawing is performed. In this 0 set, the attachment 36 is fixed at a desired angle as shown by the chain double-dashed line in FIG. 10, and the arm slide guide 15 and the arm 25 are operated to set the tip of the attachment 36 to the reference point 42 of the writing instrument 41. Can match.

Then, when creating the outline diagram on the central axis of the three-dimensional solid 60, the height of the arm slide guide 15 is operated so that the tip of the attachment 36 is moved to the center height in the width direction of the three-dimensional solid 60. Fixed to. At this time, the tip of the attachment 36 is located right above the writing instrument 41, and the height of the tip is displayed on the Z-axis scale 12.

Subsequently, while the tip of the attachment 36 is lightly contacted with the surface of the three-dimensional solid 60, the base 5 is moved on the flat surface 70, so that the writing instrument 41 is placed on the drawing sheet 75. An outline diagram in the front-rear direction on the central axis of is created.

When creating an outline diagram of another coordinate parallel to the central axis, the arm slide guide 15 is moved on the Z-axis scale 12 by a predetermined coordinate interval for drawing. Also, when drawing an outline diagram of the width direction or the plane of the three-dimensional solid 60, the placement posture of the three-dimensional solid 60 on the plane 70 is changed by 90 degrees, and the drawing is performed in the same procedure as described above. Be seen.
