The diameter of the accommodation hole is set to a size that allows at least the coil spring S to pass, as in the insertion space 7a of the accommodation portion 7 of the embodiment. Preferably, the weight 4 applies a load to the coil spring S, and the relay tool 5 disposed between the weight 4 and the coil spring S is wide enough to be accommodated. When the accommodation hole is formed in the base 6 to form the accommodation portion 7, it is desirable that the base 6 is vertically long so that the entire length of the coil spring S is accommodated in the accommodation hole.

（コイルスプリング研磨装置の実施形態）
本発明のコイルスプリング研磨装置１０の一例を、図面を参照して説明する。この実施形態は、研磨するコイルスプリングＳをコイルスプリング保持具１で保持し、当該コイルスプリングＳを研磨具２に押圧することによって当該コイルスプリングＳの研磨部を研磨する場合の例である。 (Embodiment of coil spring polishing apparatus)
An example of the coil spring polishing apparatus 10 of the present invention will be described with reference to the drawings. This embodiment is an example in which the coil spring S to be polished is held by the coil spring holder 1 and the polishing portion of the coil spring S is polished by pressing the coil spring S against the polishing tool 2.

一例として図１〜３に示すコイルスプリング研磨装置１０は、研磨具２に接触するコイルスプリングＳを研磨具２の回転により研磨するものであって、研磨具２と支持台１１とコイルスプリング保持具１を備えている。支持台１１は研磨具２の上方側に研磨具２と離して配置され、その支持台１１上にコイルスプリング保持具１が配置されている。コイルスプリング保持具１には、前記実施形態で説明したコイルスプリング保持具１を用いているため、ここでは説明を省略する。 As an example, the coil spring polishing apparatus 10 shown in FIGS. 1 to 3 polishes the coil spring S that contacts the polishing tool 2 by the rotation of the polishing tool 2, and includes the polishing tool 2, the support 11, and the coil spring holding tool. 1 is provided. The support base 11 is disposed on the upper side of the polishing tool 2 apart from the polishing tool 2, and the coil spring holder 1 is disposed on the support base 11. Since the coil spring holder 1 described in the above embodiment is used for the coil spring holder 1, description thereof is omitted here.

研磨具２は、図３に示すように、二つの回転ローラ２ａの外周に研磨ベルト２ｂが巻き付けられたもの（ベルト式研磨具）であり、一方の回転ローラ２ａに取り付けられたモータＭによって回転するものである。研磨具２は横向きに配置され、その上面（研磨面）にコイルスプリングＳの研磨部を押し当てることで、研磨部を研磨することができる。研磨具２には、水平回転する円盤状のものなど、ベルト式研磨具以外のものを用いることもできる。 As shown in FIG. 3, the polishing tool 2 is one in which a polishing belt 2b is wound around the outer periphery of two rotating rollers 2a (belt-type polishing tool), and is rotated by a motor M attached to one rotating roller 2a. To do. The polishing tool 2 is disposed sideways, and the polishing portion can be polished by pressing the polishing portion of the coil spring S against its upper surface (polishing surface). The polishing tool 2 may be other than a belt type polishing tool, such as a horizontally rotating disk.

前記支持台１１は、肉厚方向に貫通する通孔１１ａ（図１）を備えた平板であり、その表面に通孔１１ａと連通するセット孔１２ａ（図１）を備えたセット台１２が設けられている。セット台１２のセット孔１２ａにアダプタ８のはめ込み部８ｂや基体６の嵌合部６ｂをセットすることによって、コイルスプリング保持具１をセット台１２の上に載置できるようにしてある。コイルスプリング保持具１の差し込み空間７ａ内にコイルスプリングＳを収容すると当該コイルスプリングＳの研磨部が支持台１１の通孔１１ａよりも外側に露出して研磨具２に接触するようにしてある。 The support base 11 is a flat plate having a through hole 11a (FIG. 1) penetrating in the thickness direction, and a set base 12 having a set hole 12a (FIG. 1) communicating with the through hole 11a is provided on the surface thereof.

The coil spring holder 1 can be placed on the set table 12 by setting the fitting portion 8b of the adapter 8 and the fitting portion 6b of the base 6 in the set hole 12a of the set table 12. When the coil spring S is accommodated in the insertion space 7 a of the coil spring holder 1, the polishing portion of the coil spring S is exposed to the outside of the through hole 11 a of the support base 11 and comes into contact with the polishing tool 2.

一例として図１〜３に示すセット台１２は内輪１２ｘと外輪１２ｙと転動体１２ｚを備えたベアリングであり（図３）、内輪１２ｘ上に載置されるコイルスプリング保持具１を当該内輪１２ｘの回転に伴って研磨具２の研磨面と平行又は略平行に回転させられるようにしてある。コイルスプリング保持具１を回転可能とすることで、研磨部の一部のみを研磨するのではなく、研磨部の全体を均等に研磨することができる。また、コイルスプリング保持具１を回転可能とすることで、研磨具２の一部のみが摩耗するのを防止することもできる。 As an example, the set base 12 shown in FIGS. 1 to 3 is a bearing having an inner ring 12x, an outer ring 12y, and a rolling element 12z (FIG. 3), and the coil spring holder 1 placed on the inner ring 12x is attached to the inner ring 12x. Along with the rotation, the polishing tool 2 is rotated in parallel or substantially parallel to the polishing surface. By making the coil spring holder 1 rotatable, not only a part of the polishing part is polished, but the entire polishing part can be uniformly polished. Further, by making the coil spring holder 1 rotatable, it is possible to prevent only a part of the polishing tool 2 from being worn.
