Abstract

PURPOSE:To improve workability by splitting a laminate frame into two or more sections mutually fittable and assembling them by simply applying force on the laminated frame boards in the longitudinal direction. CONSTITUTION:Since punched frame boards 10 are provided with recesses 11 and protrusions 12 for jointing at both ends, the laminated or blocked frame boards 10 can be assembled by simply applying force in the longitudinal direction. Since many jigs are not required, no caution is required for management of jigs and the workability is improved. Consequently, an excellent laminate frame for DC machine can be produced with high productivity.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an improvement of a laminate frame for a DC machine.

C. Prior Art] The laminated frame of a conventional DC machine is made by dividing a frame blank 1 into four equal parts as shown in FIGS. 3 to 7 (see Japanese Utility Model Publication No. 61-34838). )This 4
Four blocks A (see Fig. 4) are made by stacking equally divided frame blanks 1, and in this case, the parts T and ■ are welded over the entire length. This block A4 is assembled using a jig with side plates 2 arranged in the front and rear, reinforcing plates 4 are brought into contact with and welded to the abutting portions of each block, and legs 5 are welded to the lower part. Laminate frame 6 (Figures 5 and 6)
(see figure).

[Problem to be solved by the invention] In this case, when each block A is welded using a jig,
Welding must be performed with force applied in the B, C, and D directions (see Figure 7) and in the longitudinal direction of the frame, which increases the number of man-hours and also makes it difficult to manage the jig. Work efficiency was significantly reduced due to the need for careful attention.

The laminate frame 1 for a DC machine of the present invention was proposed to solve the above-mentioned problems, and its purpose is to provide an excellent laminate frame for a DC machine that is easy to assemble and has high workability. The goal is to provide the following.

"Means for Solving the Problems" In order to solve the above problems, the laminate frame of the DC machine of the present invention is constructed by fitting together the joints of each frame punched into two or more parts. Its structural feature is that it has a bonded structure.

[Function] The function of the present invention having the above configuration is as follows.

In other words, since the joint structure is such that the joints of each divided frame blank are fitted together, force is applied in the longitudinal direction of the frame to the laminated room blanks (assemble the laminated frame with a It is possible to do this, does not require many jigs, and improves work efficiency.

(Example) An example of the present invention as explained above is explained based on the drawings.
C.Explain in an interesting way.

Note that members similar to those in the prior art are designated by the same reference numerals, and explanations thereof will be omitted.

As shown in Figure 1, a frame divided into two or more parts (
At the joint portion of the left plate 10, for example, a recess 11 is formed at the left end, and a convex portion 12 is formed at the right end.

The concave portion 11 is configured to narrow toward the distal end, while the convex portion 12 is configured to widen toward the distal end at a similar angle. Therefore, the two are attached to each other by ttX, so that once they are engaged, they will not come off even if they are pulled in the direction in which they were joined.
I'm leaning on it.

The operation of this embodiment as described above is as follows.

That is, since the frame punching board 10 has the concave portion 11d5 and the convex portion 12 that fit into each other at both ends, which are joint parts, it is easy to assemble the frame punching board 10 into a substantially ring shape. When assembling a laminate frame by stacking the plates 10 or forming blocks A, force is applied in the length direction of the frame. There is no need to pay attention to this, and work efficiency is improved.

Note that the laminate frame of the DC machine of the present invention is not limited to the above-mentioned embodiment, and the joint structure of the joint part of the frame punching is as shown in Fig. Two valley-shaped four parts 13 and 2 as shown
Two mountain-shaped protrusions 14 may be used, and the shape and dimensions of the joint structure can be changed as appropriate.

[Effects of the Invention] As described above, the laminated frame for a DC machine of the present invention has a simple joining structure in which the joint parts of each of the frame blanks divided into two or more pieces are fitted into each other. With this configuration, it is possible to easily assemble frame blanks into a ring shape, and without requiring many jigs, it is possible to stack frame blanks or combine blocks A to apply force in the length direction of the frame. Since the laminate frame can be easily manufactured by adding the above and welding the reinforcing plates, side plates, and legs, it is possible to provide an excellent laminate frame for a DC machine with high workability and productivity.
