【考案の詳細な説明】
本考案は改良された測定子を有するてこ式ダイヤルゲー
ジに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lever type dial gauge with an improved measuring point.
従来、てこ式ダイヤルゲージは、測定子の基部に設けら
れたねじ部を、本体の密栓の一端に、蓋枠内部のセクタ
ーギヤーなとの拡大機構の要素とともに回動可能に設け
られた回転軸のねし孔に螺入させて使用されている。Conventionally, lever-type dial gauges have a rotary shaft that connects the threaded part at the base of the gauge head to one end of the body's airtight plug, allowing it to rotate together with an element of the expansion mechanism such as a sector gear inside the lid frame. It is used by screwing into a hole.
このため測定子が折損する場合には、必ずといってよい
ほど径の小さなねじ部の基部から折れるものである。For this reason, when the probe breaks, it almost always breaks from the base of the threaded portion, which has a small diameter.
したがって、回転軸のねし孔から折損した測定子のねじ
部を取除くことはきわめて困難であり、ダイヤルゲージ
全体を分解して、回転軸と測定子とを共に新しいものと
交換しなければならなかった。Therefore, it is extremely difficult to remove the broken threaded part of the gauge head from the threaded hole in the rotary shaft, and it is necessary to disassemble the entire dial gauge and replace both the rotary shaft and gauge head with new ones. There wasn't.
本考案は、測定子交換に際して、上述した不便さを伴う
従来のものの欠点を除去することを目的とするものであ
って、本考案によれば測定子が折損した場合でもダイヤ
ルゲージを分解することなく、容易に折損した測定子の
ねじ部を回転軸から取除くことができるので迅速に測定
子を交換できる。The purpose of the present invention is to eliminate the disadvantages of the conventional methods, which are accompanied by the above-mentioned inconvenience when replacing the gauge head.According to the present invention, even if the gauge head breaks, the dial gauge can be disassembled. Since the threaded portion of the broken gauge head can be easily removed from the rotating shaft, the gauge head can be quickly replaced.
本考案の一実施例を示す添付図面に従って以下に本考案
を詳細に説明する。The present invention will be described in detail below with reference to the accompanying drawings showing an embodiment of the present invention.
本考案によるてこ式ダイヤルゲージは、密栓１を有する
本体２を含む。The lever-type dial gauge according to the present invention includes a main body 2 having a seal plug 1 .
密栓１の一端には、蓋枠内部の拡大機構の要素（図示せ
ず）、たとえばセクターギヤー、とともに回転しうる回
転軸３が設けられており、回転軸３にはその軸線と直交
する貫通孔４があけられている。A rotary shaft 3 is provided at one end of the seal plug 1 and can rotate together with an element (not shown) of an expansion mechanism inside the lid frame, such as a sector gear.The rotary shaft 3 has a through hole orthogonal to the axis thereof. 4 is open.
孔４の内面には測定子５のねじ部６と螺合するためのめ
ねじが設けられており、測定子５は、ねじ部６を回転軸
３の孔４内に螺入することにより、回転軸３に保持され
る。The inner surface of the hole 4 is provided with a female thread for screwing into the threaded part 6 of the measuring element 5, and the measuring element 5 can be assembled by screwing the threaded part 6 into the hole 4 of the rotating shaft 3. It is held on the rotating shaft 3.
ねじ部６の先端には、すり割７が設けられ、ドライバー
等の工具が適用できるようになっている。A slot 7 is provided at the tip of the threaded portion 6, so that a tool such as a screwdriver can be used.
本考案によるてこ式ダイヤルゲージは上述した構造を有
するため、測定子５がねじ部６の基部から折れた場合で
も通常セクターギヤーなどと摩擦係合、あるいはラチェ
ット係合している回転軸３を回動させて貫通孔４を蓋枠
外方に向けさせねじ部６のすり割７にドライバー等の工
具を当て、ねじ部６を回転させることにより折損残部を
容易に取り出すことかで゛きる。Since the lever-type dial gauge according to the present invention has the above-described structure, even if the gauge head 5 breaks off from the base of the threaded part 6, the rotating shaft 3, which is usually frictionally engaged or ratcheted with a sector gear etc., can be rotated. By moving the through hole 4 to face the outside of the lid frame, applying a tool such as a screwdriver to the slot 7 of the threaded part 6, and rotating the threaded part 6, the broken remaining part can be easily removed.
ねじ部６は、測定子５を回転軸３にしっかりと保持させ
るのに充分なだけの長さを有しておればよいが、第１図
にみられるように、ねし部６の先端が孔４を貫通して反
対側に突出するようにしておくとさらに好都合である。The threaded portion 6 only needs to have a length sufficient to firmly hold the probe 5 on the rotating shaft 3, but as shown in FIG. It is further advantageous if it extends through the hole 4 and projects on the opposite side.
すなわち、この場合には、回転軸外に突出している折損
残部が鉄部を取り出す際に回転軸を回動させる手がかり
となり、ドライバーがなくとも、指先により、あるいは
ありあわせの他の工具によってねじ部６の先端をつまみ
、これを回転させて抜取ることができる。In other words, in this case, the broken remaining part protruding outside the rotating shaft becomes a clue to rotate the rotating shaft when removing the iron part, and even without a screwdriver, the threaded part 6 can be removed with your fingertips or other tools at hand. You can remove it by pinching the tip and rotating it.
また、ねじ部６の先端を孔４内の中途でとめておき、孔
４の内方端に端ぐりあるいはさらに穴を設けるようにし
てもよい。Alternatively, the tip of the threaded portion 6 may be stopped halfway within the hole 4, and a counterbore or further hole may be provided at the inner end of the hole 4.
この場合にはドライバー等の工具の適用が比較的容易で
あり、また端ぐりあるいはさら穴に適合する形状をした
先端部を有する工具を用いることにより、測定子５が折
損した際の回転軸３の回動を容易ならしめることができ
る。In this case, it is relatively easy to apply a tool such as a screwdriver, and by using a tool with a tip shaped to fit into a counterbore or a countersunk hole, the rotary shaft 3 can be can be easily rotated.
