JPH05280510A - Method for attaching part - Google Patents

Abstract

PURPOSE: To provide a low cost part attaching fixture that can attach parts without causing distortions of a part support body, even if there are some size errors between the part supporting body and the part. CONSTITUTION: A part attaching piece 8 is formed, so as to have elastic nature by providing a notch 6 around the part attaching position of a part supporting body 2 or a part 4. Because the part 4 is fixed to the part attaching piece 8, the dimensional errors between the part 4 and the part support body 2 are absorbed by the elasticity of the part attaching piece 8.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a problem in mounting or assembling parts even if the parts support such as a frame is not exactly the same in length as the various parts mounted thereon. It relates to the method of mounting the parts so as not to exist.

[0002]

2. Description of the Related Art When the length of a component is shorter than the length of a component mounting portion of a component support, when the component is mounted, the component 4 is distorted as shown by a solid line in FIG. FIG. 6 is a view of FIG. 5 viewed from the direction of arrow A. As can be seen from FIG. 6, part 4
When is short, the left and right sides of the component 4 are pulled and plastically deformed (c), and the central portion warps upward (d).

Further, as shown in FIG. 7, when the component 20 originally having the length of L1 has only the length of L2, when the component 20 is attached to the frame 22, the frame 22 is shown by the solid line.
Is deformed inward, and the other component 24 attached to the frame 22 in a cantilever manner is lowered.

In order to prevent these distortions in the prior art,
Spacers must be placed between the parts and the part supports to correct the errors, or the parts and part supports must be manufactured accurately to avoid dimensional errors. As another method, as shown in Japanese Patent Application Laid-Open No. 60-152001, the structure had to be attached to the frame through a special spring.

[0005]

In the above-mentioned prior art, it is necessary to mount the spacers or make the parts and the part support accurately, so that the number of assembling steps is increased.
There was a problem that the manufacturing cost increased. In addition, there is a problem that assembly during maintenance and repair is troublesome because of distortion of the component support after manufacturing and the necessity of using spacers. JP-A-60-15
Similarly, in the conventional technology of No. 2001, since it is necessary to provide a special spring between the component and the frame, there is a problem that the number of components increases, the structure becomes complicated, the assembly is troublesome, and the manufacturing cost increases. It was

The present invention solves the above problems,
Even if there is a slight dimensional error between the component support and the component, the dimensional error can be absorbed without using a spacer, etc., and the component support can be mounted without causing distortion, and low-cost component mounting The purpose is to provide a method.

SUMMARY OF THE INVENTION According to the present invention, there is provided a component mounting piece in which a notch is formed around a component mounting position of a component support member so as to cause elastic bending, and a component is fixed to the component mounting piece. The dimensional error between the component and the component support is absorbed by the elastic deformation of the component mounting piece to achieve the above object.

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 shows an embodiment of the present invention. In FIG. 1, 2 indicates a component support (frame), and 4 indicates a component attached to the frame. 6 cuts in the parts mounting part of the frame
Is provided, and the component mounting piece 8 is configured in the component mounting portion. Therefore, when the component mounting piece 8 is provided on the component support, the component support must be at least a plate that can be cut, or an equivalent thereof. Further, in forming the component mounting piece 8, it is not always necessary to perform a cutting process, and it may be formed as a protrusion 9 by punching or by integral molding as shown in FIG. 4 depending on the shape or mounting position of the component. Good.

If the part is shorter than the length L of the frame 2,
At the time of component mounting, the component mounting piece 8 of the frame 2 bends due to the elasticity of the material, and absorbs a dimensional error between the frame and the component. The shape of the component mounting piece 8 is determined in consideration of the weight of the component, the size of the component mounting surface, the maximum dimensional difference, that is, the amount of bending, the elastic strength of the frame material, and the like.

FIG. 2 shows various shapes of the component mounting piece 8.
These shapes are appropriately selected according to the weight of the mounting parts, the mounting position, and the like. Notch end 10 of component mounting piece 8 of FIG.
Looking at, the cut end 10 is formed in a curved shape.
This is to prevent cracks from being generated when a strong force is applied to the component mounting piece 8 or metal fatigue.

Next, a second embodiment will be described with reference to FIG. In the second embodiment, the component mounting piece 8 is provided on the component side. If the component mounting piece 8 can be provided on the component as shown in this figure, it may be provided here. Further, the component mounting piece 8 may be provided on only one side as shown in FIG. 1, or may be provided on both sides as shown in FIG.

As described above, according to the present invention,
The frame 2 is provided with the component mounting piece 8 having a shape that causes elastic bending, and the elastic deformation of the component mounting piece 8 absorbs the dimensional difference between the component and the frame. Therefore, the above object can be achieved with a simple configuration. I was able to. The configuration of the present invention is
Very easy to implement and requires no new parts. Therefore, there is an excellent effect that the dimensional accuracy does not matter so much in the manufacture of parts, and the parts mounting piece 8 can be processed at a very low cost by punching or the like. In addition, unlike the above-mentioned prior art, no distortion occurs during assembly, and there is no need to attach a special spring, so that assembly of parts is very easy.
