DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a partition plate mounting frame structure having a partition plate.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, two plates 11, 13 parallel to each other are connected to two blocks 15, 17, respectively.
Further, a partition plate mounting frame structure for mounting a plurality of partition plates 21 so as to partition a space formed between the two plates 11 and 13 and between the two blocks 15 and 17 is known. I have.

In this partition plate assembling frame structure, as shown in FIG. 6, a plurality of long holes 12 are generally punched out of one plate 11 by press working, and one plate 11 is further inserted into the long hole 12 of the plate 11. Is assembled by fitting the partition plate 21 of the above.

When assembling a frame structure including the plates 11 and 13, the partition plate 21 and the blocks 15 and 17 shown in FIG. 5, the opposing surfaces of the assembled portions of the plates 11 and 13 and the blocks 15 and 17 are relatively large. Since it is a large surface, screwing with the screw 25 is possible.

However, the partition plate 21 and the plates 11, 13
This means that screwing is impossible because there is only an assembling portion about the plate thickness of the plates 11 and 13. Therefore, a plurality of long holes 12 are punched out on one plate 11 by press working, and a plurality of partition plates 21 are fitted into these long holes 12 in a one-to-one manner. .

[0006]

However, if the width of the elongated hole 12 is not more than the thickness t of one of the plates 11, it is necessary to perform punching by the press due to the above-mentioned problems in the production technology of the partition plate assembling frame structure press. Is difficult. That is, as shown in FIG. 5 and FIG. 6, unless the slot width a of the plate 11 is larger than the plate thickness t of the plate 11 (a> t), stable press working cannot be performed.

The thickness b of the partition plate 21 and the plate 11
If the difference between the widths a of the long holes 12 is large, rattling of the partition plate 21 between the long holes 12 of the plate 11 is large, and the accuracy is deteriorated. Therefore, the plate thickness b of the partition plate 21 must be larger than the plate thickness t of the plate 11 (b> t).

Therefore, the punching of the long hole 12 in the press working in the prior art becomes unstable unless the width a of the long hole 12 is equal to or more than the plate thickness t of the plate 11. In making the structure, the only option is to increase the thickness of one of the plate 11 and the partition plate 21 or combine them with rattling.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a partition plate assembling frame structure capable of accurately mounting a plate thinner than a width of a hole into which the partition plate is inserted.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a partition plate mounting frame structure according to an embodiment of the present invention. Referring to FIGS. 1 to 3, a partition plate assembling frame structure includes a first flat plate 1 having a thin flat plate shape, and a second flat plate shape provided in parallel with the first plate 1 at a predetermined interval. It includes a plate 3 and a plurality of plate-shaped partition plates 5 provided between the first and second plates 1 and 3.

The first and second plates 1 and 3 are assembled by two blocks 4 provided at a predetermined distance from each other at both ends of the first and second plates 1 and 3 so that they are provided at a predetermined distance. It is attached. The first and second plates 1 and 3 are fixed to the two blocks 4 by screws 9. The plurality of partition plates 5 partition a space formed between the first and second plates 1 and 3 and between the two blocks 4.

The first plate 1 is provided with a plurality of elongated holes 7 having a substantially rectangular shape for fitting one end portions 6 of the plurality of partition plates 5. A pair of plate thickness surfaces 7a, 7a, which face the elongated hole 7 in the longitudinal direction thereof and face mutually parallel plate surfaces 5a, 5b orthogonal to the thickness direction of the one end portion 6,
7b.

The negative plate thickness surface 7a has a plate projection 7c formed so as to be eccentric so that the central portion in the longitudinal direction projects toward the central portion of the other plate thickness surface 7b. . The plate protruding portion 7c has a trapezoidal plate protruding surface 7d at the tip thereof facing the plate surface 5a on one side of the partition plate 5. One end 6 of the partition plate 5 is fitted between the pair of plate thickness surfaces 7a and 7b and between the other plate thickness surface 7b and the plate protrusion surface 7d. The width dimension a between the pair of plate thick surfaces 7a and 7b is substantially the same.

The plate thickness surface 7b on the other side has a recessed surface 7f formed by recessing a portion facing the plate projection surface 7d from the plate thickness surface 7b on the other side into a trapezoidal shape. The plate surfaces 5a, 5b at one end 6 of the partition plate 5 are in contact with the plate projection surface 7d and the plate plate thick surface 7b on the other side.

In this partition plate assembling frame structure, a plurality of long holes 7 are punched in the first plate 1 made of a metal plate by press working, and a plurality of the partition plates 5 are formed in the long holes 7 of the first plate 1. It is assembled by fitting the end portions 6 one to one.

Now, in the partition plate assembling frame structure, the width dimension a between the pair of plate thickness surfaces 7a and 7b is set to be larger than the thickness t of the first plate 1 in the thickness direction. Further, the thickness t of the first plate 1 is set to be larger than the thickness b of the partition plate 5 (a>t> b).

Here, the punching of the long hole 7 by the press working in the prior art becomes unstable unless the width a of the long hole 7 is equal to or more than the plate thickness t of the first plate 1. When a frame structure is made by combining the plates 1 and 3 with each other, the only option is to increase the thickness of one of the first plate 1 and the partition plate 5 or combine them with a rattling state. Even in the case of a>t> b, the partition plate 5 can be fitted and fixed to the first plate 1 with high accuracy.

[0021]

As described above, according to the embodiment, according to the partition plate assembling frame structure, a thin plate can be accurately formed by general press working by devising the shape of the long hole of the plate. Can be assembled.

Further, the plate and the partition plate can be easily and accurately combined with each other irrespective of the plate thickness, and the strength of the press die can be increased.
