Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control panel incorporating a control device, and more particularly to a support member for mounting the control device.

[0002]

2. Description of the Related Art FIG. 5 (a) is a perspective view showing a conventional control panel, in which 1 is a left side plate, 2 is a right side plate, 3 is a top plate, 4 is a bottom plate, and 5 is a controller. The support member is L-shaped and spot-welded to the left side plate 1. 6
Is a mounting hole or mounting screw formed in the support member 5. A support member having a symmetrical shape with the support member 5 of the left side plate 1 is welded to the right side plate 2 to form a pair with the left side plate 1. The left side plate 1, the top plate 3, the right side plate 2 and the bottom plate 4 are joined by welding, tacking, bolting or the like. A control device 7 is housed in the control panel and is fixed to the mounting hole or the screw 6 by screwing. Other configurations include a front door, a rear door or cover, internal wiring, and an external drawer terminal board.

FIG. 6 shows the left side plate 1, the support member 5, and the mounting holes or screw holes 6. FIG. 7 shows the left side plate 1 in the case of a double-sided mounting type in which the control device is mounted from both front and back sides. A U-shaped support member 5c is attached to the left side plate 1, and two rising surfaces of the support member 5c are
The mounting hole or screw hole 6 is machined.

Next, the operation will be described. In FIG. 5B, the jig 8 (shaded portion) having a cutout shape is abutted on the inside of the bent side surface and the inside of the bent bottom surface of the left side plate 1, and the support member 5 is aligned with the cutout portion and positioned. Then, the left side plate 1 and the supporting member 5 are joined by spot welding. Similarly, the support member 5 is joined to the right side plate 1 symmetrically with the left side plate 1.

[0005]

Since the conventional control panel is constructed as described above, when the support member 5 is welded to the left side plate 1, there is no positioning means such as a positioning jig or a positioning dowel. , Its positioning is difficult to perform easily and accurately. In the case of the L-shaped support member 5, the left side plate 1,
It may happen that the right side plate 2 is attached in reverse.

In the case of the U-shaped support member 5a, there is a possibility that the support member 5a may be attached to the left side plate 1 and the right side plate 2 upside down, or may be attached upside down. In such a control panel, the size and pitch of the mounting holes or screw holes of the supporting member are often standardized so that various control devices can be housed, and it is easy for errors to occur. Therefore, there is a problem that it is not easy to attach the support member to the side plate at the correct position and direction without using the positioning jig.

The present invention has been made to solve the above-mentioned problems, and an object thereof is to obtain a control panel which can easily position a supporting member on a side plate at a correct position without using a jig. ..

[0008]

In a control panel according to the present invention, particularly in a side plate having a support member for mounting a control device, positioning of different shapes is performed at both upper and lower ends of the back side bent portion of the left side plate. A support member that has a notch for mounting and a mounting hole for fixing the control device does not fit in the notch of the left side plate except for the normal direction of up, down, left and right, and it is positioned at an appropriate position. And welded to the left side plate. The right side plate and its supporting member are symmetrical to the supporting member integrated with the left side plate and the left side plate.

[0009]

In the control board according to the present invention, the support member is fitted in the notch of the side plate, particularly when the support member is attached to the side plate. At this point, the setting direction / position of the support member with respect to the side plate is accurately determined, and the support member is joined to the side plate by welding.

[0010]

Embodiment 1 An embodiment of the present invention will be described below with reference to the drawings. Figure 1
In FIG. 1, reference numeral 1 denotes positioning notches 9 and 1 having different shapes in the bent portions in the upper portion 1a and the lower portion 1b on the inside.
0 is a left side plate, 5 is a support member having notches (upper) (lower) 11 and 12 at the upper and lower ends of the left slope contact surface, and is fitted to the left side plate 1 and joined by welding, 6 is An attachment hole or a screw hole for fixing a control device or the like provided on the support member. A is the notch length at the upper end of the support member 5a, B is the notch length at the lower end, and C and D are the depths of the notches provided at the upper and lower ends of the back side cut and bent portion of the left side plate 1. And
There is a relation of A>C>B> D.

Next, the operation will be described. Support member 5a
Place the rising portions of the upper and lower ends of the so that they fit into the upper notch (upper) 9 and the lower notch (lower) 10 of the left side plate. At this time, since C> B, it is impossible to fit the support member 5a upside down by mistake, and therefore the support member 5a can be prevented from being attached upside down. Further, by fitting the support member 5a into the notches (upper) (lower) 9, 10 of the left side plate 1, the support member 5a
Can be accurately and simply positioned. After the positioning is determined, the support member 5a and the left side plate 1 are joined by spot welding.

FIG. 2 shows an example in which a notch is provided only at the lower end of the back side bent portion of the left side plate 1. In this case, it is necessary to apply the lower end of the support member 5b to the notch in the lower portion of the left side plate 1 and position it in parallel with the left side plate 1. or,
Although the function of attaching the upper and lower sides cannot be provided, the support member 5b can be positioned relatively easily by notching only one left side plate.

Second Embodiment In the following embodiment, the case of the one side mounting type has been described, but the front and rear both sides mounting type may be used. In FIG. 3, the U-shaped support member 5c has a notch leaving only one vertical surface 15 at the lower end, and the U-shaped support member 5c fits into the upper end of the back side bent portion of the left side plate 1. 14 is provided, and a notch 13 into which the rising surface 15 is fitted is provided at the lower end. E is the length of the notch rising surface, and F is the depth of the notch 14. When the support member 5c is fitted into the upper and lower cutouts of the left side plate 1, even if the support member 5c is mistakenly attached upside down, the length E of the cutout portion rising surface cannot be fitted in the hindrance. Instead, it has the same effect as the first embodiment. Further, even if the left and right support members 5c are mixed up, they cannot be mounted.

FIG. 4 omits the notch in the upper part of the left side plate, and it is necessary to position the lower end of the supporting member 5c by the notch in the left side plate and place it in parallel with the left side plate, but it is relatively easy. You can Further, in this case, the same effect as the second embodiment is obtained.

[0015]

As described above, according to the present invention, the notches for positioning are provided in the bent portions in the upper portion and the lower portion inside the side plate so as to have different shapes, and the notches for positioning are provided. Since the support parts with notches at the upper and lower ends are provided so that they can be fitted to the side plate, when mounting the support member to the side plate, it is possible to easily position it at an accurate position without a jig. effective.
