料４を載置し、この試料４の上に鋼球３を置く。Next, the operation of the steel ball drop impact test apparatus 20 will be described. First, the position of the stop plate 7 is adjusted to a height at which the steel ball 3 is dropped. The impact test sample 4 is placed on the sample stage 6, and the steel ball 3 is placed on the sample 4.

The drive shaft 1a is stopped. At this time, the steel ball 3 is attracted to the permanent magnet 2. By thus providing the gap 12 between the steel ball 3 and the permanent magnet 2 when the steel ball 3 is attracted, no force is applied to the sample 4.

て、鋼球３が落下し、試料４に衝突し、衝撃を与える。Next, by raising the drive shaft 1a of the air cylinder 1, the steel ball 3 attracted to the permanent magnet 2 rises inside the steel ball guide 5. When the steel ball 3 reaches the position of the stop plate 7, the steel ball 3 is separated from the permanent magnet 2 by the rising force of the fixed stop plate 7 and the drive shaft 1a.
That is, after the steel ball 3 reaches the position of the stop plate 7, the air cylinder 1 rises to the upper stopping point, but the steel ball 3 does not rise higher than the stop plate 7 and falls away from the permanent magnet 2. Then, the steel ball 3 falls, collides with the sample 4, and gives an impact.

くすることができる。According to the first embodiment, since the steel balls 3 are attracted by the permanent magnets 2 and separated by the stop plates 7, the manufacturing cost of the apparatus can be reduced. That is, in the conventional steel ball impact test apparatus, since the steel ball is attached and detached by an electromagnet or a mechanical method, a mechanical drive component such as an expensive coil or an expensive air chuck is required as compared with the permanent magnet 2. On the other hand, if the attachment and detachment of the steel ball 3 is performed by the permanent magnet 2 and the stop plate 7, the cost of the parts of the apparatus can be reduced. Therefore, the manufacturing cost of the device can be reduced.
【００２５】また、鋼球３の着脱を永久磁石２と停止板

長時間の連続使用（連続動作）に適している。Further, since the attachment and detachment of the steel ball 3 is performed by the permanent magnet 2 and the stop plate 7, even when the collision between the steel ball 3 and the sample 4 is repeated for a long time, the ON / OFF of the electromagnet as in the conventional apparatus is performed.
This does not cause the heat deterioration of the coil portion due to the repetition of the above. Therefore, the steel ball drop impact test apparatus 20 is suitable for long-time continuous use (continuous operation).
【００２６】また、鋼球３の着脱を永久磁石２と停止板

いる。Further, since the attachment and detachment of the steel ball 3 is performed by the permanent magnet 2 and the stop plate 7, the steel ball 3 can be attached and detached instantaneously.
Therefore, even when the collision between the steel ball 3 and the sample 4 is repeated a plurality of times, a fixed operation time is not required for attaching and detaching the steel ball unlike a conventional device for attaching and detaching the steel ball with an air chuck. The test can be performed in a shorter time than the device of the above. Therefore, it is suitable for a collision test that is repeated a plurality of times.
【００２７】また、鋼球３の着脱を永久磁石２と停止板
７で行うため、落下高さを正確に再現しやすい。したが
って、正確な鋼球落下衝撃試験を実現できる。Further, since the steel ball 3 is attached and detached by the permanent magnet 2 and the stop plate 7, it is easy to accurately reproduce the drop height. Therefore, an accurate steel ball drop impact test can be realized.
【００２８】また、停止板７の位置を長穴９で変更する
ことにより、鋼球３の落下の高さを任意に設定できる。
これにより、試料４に与える衝撃力を適宜変更すること
ができる。By changing the position of the stop plate 7 with the elongated hole 9, the height at which the steel ball 3 falls can be set arbitrarily.
Thereby, the impact force applied to the sample 4 can be changed as appropriate.
【００２９】また、鋼球３の吸着を永久磁石２で行い、
従来の装置のように鋼球の保持部に通電部や駆動部がな
いので、保守が容易である。Further, the steel balls 3 are attracted by the permanent magnets 2,
Maintenance is easy because there is no current-carrying part or drive part in the holding part of the steel ball as in the conventional device.
【００３０】尚、上記第１の実施の形態では、鋼球ガイ
ド５の長穴９に停止板７をネジによって取り付けている
が、鋼球ガイド５の長穴９に他の方法によって停止板７
を取り付けることも可能である。In the first embodiment, the stop plate 7 is attached to the long hole 9 of the steel ball guide 5 by a screw, but the stop plate 7 is attached to the long hole 9 of the steel ball guide 5 by another method.
It is also possible to attach.
