0 to the side opposite to the main scale 9 with respect to the fixed jaw 2,
There are movable jaws 1 and 1 on the main scale 9 and the auxiliary foot 10, respectively.
1, the movable jaw 11 of the auxiliary leg 10 is shaped to be able to move past the fixed jaw 2, and each jaw is provided with an outer measuring surface and an inner measuring surface. The width dimension between the outer measurement surface and the inner measurement surface of the movable jaw 11 of the auxiliary foot 10 is set equal, and the width dimension between the auxiliary foot and the outer measurement surface of the fixed jaw 2 is set to be equal. The outer measuring surface of the movable jaw 11 of 10 is set parallel to the inner measuring surface of the fixed jaw 2, and the inner measuring surface of the movable jaw 11 of the auxiliary foot 11 is set parallel to the inner measuring surface of the movable jaw 11 of 10, and a fixing screw is provided on each movable jaw 1, 11. The present invention relates to a caliper with a variable limit gauge, which is characterized by the above features, and relates to a caliper that is used inside and outside.
従来のノギスは内・外側の測定に広く使用されているが
、同一寸法で製作された多数の部品の同−公差部の繰り
返し測定には非能率的であり、また目盛りの判読の繰り
返しによる作業者の疲労及びそれに起因する測定不良も
生じ易いのである。Conventional calipers are widely used for internal and external measurements, but they are inefficient for repeatedly measuring the same tolerance of many parts manufactured with the same dimensions, and the work requires repeated reading of the scale. Fatigue of the operator and resulting measurement errors are also likely to occur.
従来この様な同一寸法同一公差の多数の部品の内、外側
測定には「はさみゲージ」「栓ゲージ」等のいわゆる限
界ゲージが使用されている。Conventionally, so-called limit gauges such as "scissor gauges" and "plug gauges" have been used to measure the outside of a large number of parts having the same dimensions and same tolerances.
が、呼び寸法及び公差の巾に対し汎用性を有しないため
、各測定部毎に多数のゲージを用意する必要があった。However, since it is not versatile in terms of nominal dimensions and tolerance widths, it is necessary to prepare a large number of gauges for each measuring section.
この欠点を排し汎用性を有するものとして第１図に示す
ようなリミットマイクロメーターが使用されている。A limit micrometer as shown in FIG. 1 has been used as a device that eliminates this drawback and has versatility.
これに一個の本尺９に取付けられた２本のマイクロメー
ターのうち外側の１本のスピンドルＡとアンビルＢ間の
寸法を測定値の上限値に設定し、内側の１本のスピンド
ルＣとアンビル０間の寸法を測定値の下限値に設定して
限界ゲージとして使用されてきた。Of the two micrometers attached to one main scale 9, the dimension between the outer one spindle A and anvil B is set as the upper limit of the measured value, and the inner one spindle C and anvil It has been used as a limit gauge by setting the dimension between 0 as the lower limit of the measured value.
しかしこのリミットマイクロメーターは内側測定が不可
能であり、通り、止りの基準面が２箇所に分かれている
関係から一つの寸法判定に２回の測定を必要とした。However, this limit micrometer cannot measure the inside, and because the reference planes for pass and stop are separated into two locations, two measurements are required for one dimension determination.
またマイクロメーターの製作上の制約から呼び寸法の設
定範囲も狭い〔一般に２５ｍｍ〕といった欠点を有して
いる。Furthermore, due to manufacturing constraints of the micrometer, the setting range of nominal dimensions is also narrow (generally 25 mm).
本発明はノギスに測定寸法の公差の巾を設定する補助ジ
ョーを取付けることにより内側、外側用の限界ゲージと
しての機能を付与するとともに、従来のノギスとしての
使用も可能にし、上述の従来の測定方法の欠点を補うも
のである。The present invention provides a function as a limit gauge for inside and outside by attaching an auxiliary jaw to the caliper to set the width of the tolerance of the measurement dimension, and also allows it to be used as a conventional caliper. It compensates for the shortcomings of the method.
発明の内容を■■ついて説明する。The content of the invention will be explained in detail.
第２図に於て主尺の目盛を■■だ本尺９はその一端に本

６によって本尺９に固定セントする構成に従来から使用
されているものと同じである。In Figure 2, the scale of the main scale is shown as 1, and then use the fine adjustment knob 7 to finely move this movable jaw 1.
This configuration is the same as that conventionally used for fixing the fine adjustment jaw 12 having a fine adjustment knob fixing screw 6 to the main scale 9.

整し得る構成となっている。In the caliper according to the present invention, the main scale 9 is extended to the fixed jaw 2 side of the main scale to constitute an auxiliary foot 10 for setting the tolerance width, and the movable jaw 11 of the auxiliary foot is slidably attached to the auxiliary foot 10. For fine adjustment of the movable jaw 11, the movable jaw 11 can be movably adjusted using a fine adjustment jaw and a fine adjustment screw fixedly set on the jaw 11.

定面３ａを、固定ジョー２の内側測定面２ｂに対して補
助足１０の可動ジョー１１の内側測定面２ｂをそれぞれ
平行に設定して構成されている。When the outer measuring scale 4 of the husband's auxiliary leg and the inner measuring scale 5 of the auxiliary leg are set to 0, the tip part 3 of the movable jaw 11 has an outer measuring surface 3a and an inner measuring surface 3b, which are the main scale. In other words, the outer measurement surface 2a of the fixed jaw 2 should be flush with the outer and inner measurement surfaces 2a and 2b of the fixed jaw 2, respectively.
and the inner measuring surface 2b and the width dimension between the outer measuring surface 3a and the inner measuring surface 3b of the movable jaw 11 of the auxiliary foot 10 are set to be equal, and the outer measuring surface of the fixed jaw 2 is set to the same width. The outer measuring surface 3a of the movable jaw 11 of the auxiliary foot 10 is set parallel to 2a, and the inner measuring surface 2b of the movable jaw 11 of the auxiliary foot 10 is set parallel to the inner measuring surface 2b of the fixed jaw 2. ing.
従って２ａと３ａあるいは２ｂと３ｂが同一平面になる
ように可動ジョー１１を固定して使用する場合は本ノギ
スは従来のノギスとしての機能をもつことになってくる
。Therefore, when the movable jaw 11 is fixed so that 2a and 3a or 2b and 3b are on the same plane, this caliper functions as a conventional caliper.
然るに第４図及び第５図に示すように補助足の可動ジョ
ー３を固定ジョー２に対してＣだけずらせた位置に移動
固定することにより、夫々呼び寸法Ａに対し公差中が＋
Ｃの範囲内を測定する限界ゲージの機能を有することに
なるのである。However, as shown in FIGS. 4 and 5, by moving and fixing the movable jaw 3 of the auxiliary leg to a position shifted by C with respect to the fixed jaw 2, the tolerance is ++ for the nominal dimension A, respectively.
It has the function of a limit gauge that measures within the range of C.

差範囲Ａ＜Ｓ＜Ｂに入っているか否かを検査すればよい
場合に於ては、第４図の位置に固定したノギスを被測定
箇所に限界ゲージの要領であてがうことにより容易に検
査判定できるのである。In other words, in Figure 4, when the dimension of the object to be measured is S, the purpose of measurement is to determine whether S is within the specified tolerance range A<S<B rather than the absolute value of the length of S. In cases where inspection is sufficient, the inspection can be easily determined by applying a caliper fixed at the position shown in FIG. 4 to the point to be measured in the same manner as a limit gauge.
第４図に於て１ｂ−３ｂ間を通り１ｂ−２ｂ間で止まれ
ば被測定寸法Ｓは公差内にあるものと判定される。In FIG. 4, if it passes between 1b and 3b and stops between 1b and 2b, it is determined that the measured dimension S is within the tolerance.
本発明は上述のような構成機能を持つものであるから従

とが可能なばかりでなく、（補助足の可動ジョー３の位
置を本尺の固定ジョー２に対して公差の申分だけ移動し

ができる。Since the present invention has the above-mentioned structural functions, it is not only possible to read the inside and outside measured values like the conventional caliper, but also it is possible to read the position of the movable jaw 3 of the auxiliary foot on the main scale. can be used as a limit gauge (by moving it by the amount of tolerance and fixing it with respect to the fixed jaw 2).
公差の巾は上述の補助の可動ジョー３の移動固定による
。The width of the tolerance depends on the fixed movement of the auxiliary movable jaw 3 mentioned above.
が、呼び寸法の差は本尺の固定ジョー２の移動固定によ
って行われることは当然である。However, it is a matter of course that the difference in nominal size is made by moving and fixing the fixed jaw 2 of the main scale.
従って呼び寸法の設定範囲もマイクロメーターを基とし
たものに比し広くとれ、内側測定も外側測定と同様に実
施可能となるのである。Therefore, the setting range of nominal dimensions can be wider than that based on micrometers, and inside measurements can be carried out in the same way as outside measurements.
また公差中の変更、呼び寸法の変更が個々に行えるので
検査等級の変更等に対しても容易に対応し得るものであ
る。Furthermore, since changes in tolerances and nominal dimensions can be made individually, changes in inspection grades can be easily accommodated.

合否判定が可能となる、（（また測定基準面が広いので
（被測定物との接触面積が広いため）測定作業が安定し
測定誤差も少ない。Compared to known limit micrometers, the non-passing reference surface is concentrated in one place, making it possible to make a pass/fail judgment with a single measurement operation. (Because the contact area is wide) measurement work is stable and measurement errors are small.

呼び寸法及び公差の巾の設定に際してはブロックゲージ
等の基準によって設定することも可能であるから微調整
用ジョー１２及び微調整用ツマミ７は必ずしも無くても
よく。When setting the nominal dimensions and the width of the tolerance, it is also possible to set them using a standard such as a block gauge, so the fine adjustment jaw 12 and the fine adjustment knob 7 may not necessarily be provided.
同様の理由によって補助足１０及び補助足の可動ジョー
の主目盛及び副尺目盛も省略可能である。For the same reason, the main scale and vernier scale of the auxiliary foot 10 and the movable jaw of the auxiliary foot can also be omitted.
