本発明はコイルバネ圧縮変形時の変形姿勢を測定する装
置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for measuring the deformed posture of a coil spring during compressive deformation.
［従来の技術］

している。[Prior Art] Coil springs are often used as elastic support members in various devices, but a coil spring is designed that deforms while the support surface, which is one end of the spring, always remains parallel to the seat surface, which is the other end, when compressed. Since mass production is difficult due to processing technology, the supported body is usually provided with a guide so that it can move while maintaining a predetermined posture regardless of the deformed posture of the coil spring.
［発明が解決しようとする課題］
しかしながら、例えば電磁弁の弁体支持等に使用する場

いる。[Means for Solving the Problems] To explain in detail the present invention, a horizontal base 1 (FIG. 1),
A positioning part 11 formed on the horizontal base 1 to position the coil spring S in a vertical position, a displacement magnifying plate 2 placed on the positioned coil spring S, and a plate surface of the displacement magnifying plate 2. Distance measuring means 3 for measuring the opposing distance of , and the distal end of the displacement magnifying plate 2 make point contact with the upper surface portion through which the axis of the coil spring S passes, and press and deform the coil spring S through the displacement magnifying plate 2. A pressing member 4 is provided.

生じてその姿勢が変化する。[Operation] In the above measuring device, when the pressing member 4 is brought into point contact with the displacement magnifying plate 2 and the coil spring S is pressed and compressed, an uneven load may be generated inside the coil spring S depending on variations in processing. A difference occurs in the amount of contraction of each part of the coil spring S, and its posture changes.

バネＳのみを速やかに選択することができる。When the posture changes, the displacement magnifying plate 2 placed on the coil spring S makes an angle with respect to the horizontal, and the distance to the plate surface measured by the distance measuring means 3 changes greatly. Therefore, the extent of the attitude change of the coil spring S can be known reliably and quantitatively from this distance change, and only the coil spring S that satisfies the specifications can be quickly selected.

is supported. The rotary table 8 has a central cylindrical portion 81 rotatably fitted around the outer periphery of the shaft 6 and supported by the bearings 71 and 72, and a stay 31 on the plate portion 82 at the upper end.
For example, an eddy current detection type distance sensor 3 is supported by the stay 31. This distance sensor 3 is provided toward the outer periphery of the plate surface of the displacement magnifying plate 2 and measures the facing distance.

勢されている。A steel ball 41 held by a holder 42 constituting a pressing member is in contact with the center upper surface of the displacement magnifying plate 2 that coincides with the axis of the coil spring S, and the holder 42 is held horizontally via a knuckle 43. It is fixed to a support beam 91 that extends to. This support beam 91 has both ends (only one shown) fixed to a slider 92 provided vertically movably on the post 51 installed on the base plate 5, and the slider 92 is attached to a spring provided between the top end and the post 92. It is urged downward by a member 93.

Next, when the slider 92 is lowered to bring the steel ball 41 into contact with the center of the displacement magnifying plate 2, the steel ball 41
receives the spring force of the spring member 93 and compresses and deforms the coil spring S via the displacement magnifying plate 2.

サ３により検出される距離は変化しない。If the attitude of the coil spring S during deformation does not change, the displacement magnifying plate 2 descends while maintaining its horizontal attitude (FIG. 3). Therefore, even if the rotary table 8 is rotated and the distance sensor 3 is moved circumferentially around the center of the displacement magnifying plate 2, the distance detected by the sensor 3 does not change.

離は変化する。On the other hand, during the compressive deformation, when an eccentric load is generated inside the coil spring S and its posture changes, the displacement magnifying plate 2 is tilted from the horizontal as shown in FIG. 4, and the rotary table 8 causes the distance sensor 3 to move around. The detection distance changes depending on the moving position.

In this embodiment, since the inclination of the support surface is magnified into a distance difference by the displacement magnifying plate 2 and detected, highly accurate measurement is possible.
