Abstract

PURPOSE:To provide a tool for correcting distortion of a resin plotter base board at low cost which can be adjusted easily, and a method therefor. CONSTITUTION:An interval between a pair of stiffening plates 5a and 5b provided on the rear face of a distorted plotter base board 3 is narrowed by the distortion of the plotter base board 3. The interval between the stiffening plates 5a and 5b is widened by inserting a wedged regulator 1 in the interval. As a result, the distortion of the plotter base board 3 is corrected. The correctly degree of the distortion is regulated by inserting degree of the wedged regulator 1 in the stiffening plates 5a and 5b by using a screw 2.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distortion correcting tool for a resin plotter baseboard and a correction method therefor.
Particularly, the present invention relates to a straightening tool for a plastic plotter base board which is low in cost and simple, and a method for correcting the same.

2. Description of the Related Art FIG. 3A is a view showing a conventional distortion correcting tool for a resin plotter base board.

FIG. 3 (B) is a view of the resin plotter base board 3 as seen from the back surface thereof, and FIG. 3 (A) is a view taken along the line AA in FIG. 3 (B), and FIG. ) Is a cross-sectional view of a portion indicated by CC in FIG.

The conventional plotter base board 3 is originally provided with a pair of reinforcing plates 20a and 20b as shown in FIG. However, in reality, even if such reinforcing plates 20a and 20b are provided, the plotter base board 3 is deformed as shown in FIG.

In such a case, in the conventional case, a U-shaped reinforcing member 21 made of iron is inserted between a pair of reinforcing plates 21a and 21b as shown in FIG. As shown in (C), such a distortion is corrected by tightening the nut 22 fixed to the plotter base board 3 to integrate the reinforcing material 21 with the plotter base board 3.

[0006]

SUMMARY OF THE INVENTION In the conventional plotter base board deflection correcting method as shown in FIG.
Since the number of parts such as the reinforcing member 21, the screw 23, and the nut 22 is large, the cost is high and the plotter base board 3 itself is heavy. Also, it took a long time to adjust because there were many parts.

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a bending correction tool for a resin plotter base board and a correction method thereof, which is inexpensive and can be easily adjusted. To aim.

[0008]

According to a first aspect of the present invention, at least one pair of reinforcing portions extending in parallel at a constant interval are provided on the rear surface, and a predetermined amount is provided on the rear surface between the pair of reinforcing portions. The strain correction tool for correcting the strain on the surface side of the resin plotter base board provided with screw holes at intervals has a substantially wedge-shaped cross section, and the width of the wedge-shaped tip is 1 when the plotter base board is distorted
The width of the wedge-shaped rear end is set to be larger than the distance between the release-side ends of the pair of reinforcing portions, and the width of the wedge-shaped rear end is set to be larger than the distance between the release-side ends in the above-described state. It includes an expansion member having an insertion hole extending toward the end side, and a screw which is inserted into the insertion hole of the expansion member and which is screwed into the screw hole.

According to a second aspect of the present invention, there is provided a straightening method for a resin plotter board having at least a pair of reinforcing portions extending in equilibrium at regular intervals on the back surface, which is released by distortion to the front surface side of the plotter baseboard. The strain corrector according to claim 1 is provided between the pair of reinforcing portions having a smaller side distance,
The step of pushing in from the tip end side and the step of correcting the distortion of the plotter base board by expanding the release side of the pair of reinforcing portions are included.

[0010]

According to the first aspect of the present invention, a wedge-shaped expansion member having a rear end portion in which a space between both ends of the release side narrowed by the distortion of the base board is set larger than that is inserted between the pair of reinforcement members. Then, the expansion member is fixed to the reinforcing member with the screw to widen the gap between the both ends on the release side, and accordingly, the distortion of the plotter base board is corrected.

In the method according to the second aspect of the present invention, the distance between the open-side ends of the pair of reinforcing members narrowed by the distortion of the plotter base board is widened, thereby correcting the distortion of the plotter base board.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic view showing the details of the distortion correcting tool for the plotter base board 3 according to the present invention. Referring to FIG. 1, wedge-shaped corrector 1 is inserted between a pair of reinforcing plates 5 a and 5 b provided on the back surface of plotter base board 3. The upper width of the straightening tool 1 is wider than the width of the pair of reinforcing plates 5a and 5b, and the straightening tool 1 has a wedge shape, so that the straightening tool 1 is inserted between the pair of reinforcing plates 5a and 5b. Then, the narrowed space between the reinforcing plates 5a and 5b is widened.

This situation will be described with reference to FIG. Figure 2
(C) is a view of the plotter base board 3 as seen from the back side, as in FIG. 3. A pair of reinforcing plates 5a and 5b are provided in the direction in which the plotter base board 3 intersects with the direction in which it is easily warped. 2A is a diagram showing a distorted state of the plotter base board 3 and FIG. 2B is a diagram showing a state after the distorted plotter base board 3 is corrected. 3A and 3B are both arrow views of the portion indicated by AA in FIG.

When the plotter base board 3 is distorted as shown in FIG. 2A, the wedge-shaped corrector 1 shown in FIG. 1 is inserted between the pair of reinforcing plates 5a and 5b. To do. Then, a pair of reinforcing plates 5a spaced by it,
The interval of 5b is widened, and as a result, the distortion of the plotter base board 3 is corrected as shown in FIG. In addition, how much the correction tool 1 is fixed by the screw 2 to the pair of reinforcing plates 5a and 5b
The decision as to whether it should be inserted between is made as follows.

That is, the horizontal gauge 11 is placed on the distorted plotter base board 3 as shown in FIG. The screw 2 may be tightened to the nut 4 via the corrector 1 until the plotter base board 3 is aligned with the horizontal line of the gauge 11.

In FIG. 2, three correction tools 1a, 1b, 1c are used as shown in FIG. 2C, but if the amount of distortion is large, this number can be increased.

[0018]

As described above, according to the present invention, the gap between the two ends on the release side of the pair of reinforcing plates narrowed by the distortion of the plotter base board is widened by the expanding member composed of the wedge member, and thereby, The distortion of the plotter base board is corrected. Distortion can be eliminated simply by fixing a small number of small wedge-shaped orthodontic appliances to the plotter base board, so the weight can be reduced and adjustments do not take time.

As a result, there is an effect that it is possible to provide a bend correction tool for a resin plotter base board which is light and easy to adjust, and a bend correction method therefor.
