〔実施例〕
以下、本発明を実施例について図面により詳細に説明す
る。[Example] Hereinafter, the present invention will be described in detail with reference to the drawings with regard to an example.
第１図〜第３図に本発明による種々のねし孔周マスキン
グ手段を示す。FIGS. 1 to 3 show various means for masking the circumference of a tapped hole according to the present invention.
第１図のマスキング手段は、比較的太い軸部材１と比較
的細いワイヤからなるばね部２が別々の部材から構成さ

り係止されている。In the masking means shown in FIG. 1, a relatively thick shaft member 1 and a spring portion 2 made of a relatively thin wire are constructed from separate members, and the spring portion 2 is locked in a horizontal hole of the shaft member 1 by its inner protruding portion. has been done.

体に形成しても勿論差し支えない。In the spring part 2, two wire legs 3.3' form an outwardly projecting bulge 4.4' and are joined together at a curved part 5 at the lower end. A metal disc or square plate-shaped head 6 is fixed to the upper part of the shaft member 1 by appropriate means, and a silicone rubber or Teflon type seal member 7 is fitted to the shaft member 1 below. . Note that the head 6 may of course be formed integrally with the shaft member l.
第２図に別のマスキング手段の実施例を示す。FIG. 2 shows an embodiment of another masking means.

ている。なお、１７はシール部材を示す。The masking means shown in FIG. 2 is particularly different from the one shown in FIG. 1. A gripping portion 1B is formed for gripping the masking means when inserting or removing the masking means into a screw hole. Furthermore, in this embodiment a bulge I4.14' of the spring part 12 is formed in the upper part of the leg part 13.13'. Note that 17 indicates a sealing member.

キング手段が最も製造が容易である。FIG. 3 shows a modification of the masking means shown in FIG. 2. Third
The illustrated embodiment differs from the embodiment illustrated in FIG. 2 in the rhombic shape of the spring portion 22 made of wire. The masking means of this embodiment is the easiest to manufacture.
これらの実施例に示したように、ばね部は軸部材と一体

、ばね部は下端で連結された二つのワイヤの脚部が弾力
をもってねし孔面と当接するふくらみをもっているよう
に形成すれば、どんな形状でも差し支えない。As shown in these embodiments, the spring portion may be integral with the shaft member or may be a separate member. Further, the spring portion may have any shape as long as it is formed so that the legs of the two wires connected at the lower ends have a bulge that elastically abuts against the screw hole surface.

するばね力でマスキング手段を上方へ移動しないように
保持し、かつシール部材２７が部品３０の面に圧接され
てねし孔内部に処理液が浸入しないように防止される。FIG. 4 shows the masking means of FIG. 3 inserted into a threaded hole 31 of a part 30 to be electroplated or electrocoated. The bulge 24.24' of the spring part 22 is the screw hole 31.
The masking means is compressed by contacting the inner surface of the part 30, and the spring force of the spring part tries to return due to elasticity to hold the masking means from moving upward, and the sealing member 27 is pressed against the surface of the part 30 and is processed inside the screw hole. Prevents liquid from entering.
ねじ孔を有する部品３０は電着塗装または電気メッキ後
、炉に入れて焼付されるので温度が２００°Ｃ位になる
が、そのとき密閉されたねじ孔内部の空気が熱膨張する
と、シール部材２７がたわんで緩衝することができる。After electrodeposition coating or electroplating, the part 30 with a screw hole is baked in a furnace, so the temperature reaches about 200°C. At that time, when the air inside the sealed screw hole thermally expands, the sealing member 27 can be bent and buffered.
シール部材は、シリコンゴムまたはテフロンのような耐

た、第５図のシール部材３７のように、平板状の本体中
心から突出するテーパー部３７ａを形成し、このテーパ
ー部をねじ孔に押し込んで位置がずれないようにするこ
ともできる。The seal member is suitably made of a heat resistant and elastic material such as silicone rubber or Teflon. The spring part can be made of iron or other metal wire. Further, as in the sealing member 37 shown in FIG. 5, a tapered portion 37a may be formed to protrude from the center of the flat plate-like body, and this tapered portion may be pushed into a screw hole to prevent displacement.
本発明によるねじ孔周マスキング手段は、ねじ孔に係止

ができると共に、密閉されたねじ孔内部の空気の熱膨張
を緩衝することもできる。The threaded hole circumferential masking means according to the present invention is constituted by a shaft member having a spring portion that is engaged with the threaded hole, so that the masking means can be easily and quickly attached to the threaded hole during electroplating or electrodeposition painting. It can be inserted and removed, reducing work time. In addition, since it has an elastic heat-resistant sealing member under the head attached to the shaft member, it is possible to seal the screw hole when inserted into the screw hole, and also to seal the screw hole inside the screw hole. It can also buffer the thermal expansion of air.
また、軸部材の頭部の上に把持部を形成することにより
取扱やすくなり、作業性が向上する。Further, by forming a grip portion on the head of the shaft member, it becomes easier to handle and workability is improved.
また、シール部材にその平板状本体中心から突出するテ
ーパー部を形成すれば、このシール部材をねじ孔に押し
込んだ場合に位置がずれないという利点がある。Further, if the sealing member is formed with a tapered portion protruding from the center of its flat body, there is an advantage that the sealing member will not be displaced when pushed into the screw hole.
