Description

[Detailed Description of the Invention] This invention relates to an alignment tool for magnetic material parts.

Conventionally, after processing and forming soft magnetic materials into stators,
When performing magnetic annealing, if the plate-shaped stator parts were processed together as they were, they would fuse where they overlapped, so alumina powder was applied to each part in advance before processing. However, applying alumina powder to each sheet is time-consuming and requires cleaning after heat treatment. Therefore, it is conceivable to partition the parts with partitions so that they do not come into contact with each other during heat treatment. The present invention provides an alignment tool for aligning parts at intervals in advance so that they can be easily partitioned using a partitioning tool.

Next, embodiments of the present invention will be described.

The box-shaped case 1 includes a bottom plate 2, side plates 3, 4, end plates 5,
The bottom plate and side plates are made of non-magnetic material, and the end plates are made of magnetic material. The end plates 5, 6 are provided with elongated holes 7, 8, 9, 10 at symmetrical positions, respectively. Two component support rods 11 and 12 are slidable vertically through these holes. This box-shaped case 1 houses magnetic parts 13 such as stator parts as shown in the third diagram, and the part support rods 11 and 12 are used to arrange these parts at predetermined positions inside the case. . In accordance with the shape of part 13, the shape of case 1,
The positions of holes 7 to 10, the number of support rods 11 and 12, etc. are set.

When using, first, some magnetic material parts 1
3 into the case 1 and pass the support rods 11 and 12 through. This is the state shown in the fourth figure. Then, the fifth
As shown in the figure, the case 1 is placed in the magnetic field forming means 14. Since the side plates 3 and 4 have N and S poles facing each other, as shown in Figure 6, the adjacent parts 1
3 exerts a repulsive force on each other, and the parts are spaced apart from each other along the support rods 11 and 12. At this time, if the parts 13 overlap and there are some parts that are not completely separated due to friction between the case 1 and the parts, the support rod 1
Complete the separation by shaking numbers 1 and 12. Note that, as described above, the end plates 5 and 6 are made of a magnetic material. Therefore, the parts adjacent to the end plate are also spaced apart from the end plate. After arranging the parts 13 in this way, a partition 15 as shown in FIG. The parts are removed from the case 1 while being sandwiched between them, or the parts are heat-treated while being placed in the case.

According to the magnetic material component aligning tool according to the present invention having the above-described configuration, a large number of magnetic material components can be quickly aligned.
