のである。Therefore, these alternative mechanisms are within the scope of the present invention.
上記構或の実施につき、その作用効果を説明する。The effects of implementing the above structure will be explained.
先ず、操作棒の挾持部５に熱電対線を把持させる。First, the thermocouple wire is gripped by the clamping portion 5 of the operating rod.
すなわち、第３図Ｃに示すように外筒１に対し操作棒の
プッシュ部１１を閉爪用スプリング１３の弾力に抗して
圧入し扶持部５を開く。That is, as shown in FIG. 3C, the push portion 11 of the operating rod is press-fitted into the outer cylinder 1 against the elasticity of the closing claw spring 13 to open the supporting portion 5.
図中、羽根付き符号は部材の移動方向を示し、以下も同

先端方向に移動されるから、その可動爪７は開爪用スプ
リング８によって自動的に基部を中心にテーパー壁２と
の間隔の許す範囲で横方向に開かれる。Since the set claw is moved toward the open end of the tapered wall 2 by lowering the operating rod, the movable claw 7 is automatically moved by the claw opening spring 8 within the range allowed by the distance from the tapered wall 2 around the base. It opens horizontally.
その際、可動爪７は案内軸９によって案内されているか
ら脱落のおそれはない。At this time, since the movable claw 7 is guided by the guide shaft 9, there is no risk of it falling off.
開かれた溝１０に熱電対線２０を、細管内周壁に取付け

いで第３図Ｅに示すようにプッシュ部１１の押圧を解除
して可動爪７を閉じ扶持部５をして熱電対線２０を確実
に把持させる。The thermocouple wire 20 is inserted into the open groove 10, and when the thermocouple wire 20 is attached to the inner peripheral wall of the capillary tube, use the groove 10a, and when the thermocouple wire is attached to the bottom wall of the capillary tube, use the groove 10b. , and then connect the thermocouple coupling end 21 at the tip to the required length (
If groove 10a is used, groove 10 is placed outside the outer periphery of the outer shell.
When using b, make the thermocouple wire 20 stick out as short as possible) from the claw, then release the push part 11 and close the movable claw 7 to secure the thermocouple wire 20 as shown in Fig. 3E. hold it.
すなわち、プッシュ部押圧の解除により閉爪用スプリン
グ１３は開爪用スプリング８の弾力に抗して可動爪７を
閉じさせながら操作棒を上方に移動させるものである。That is, when the push part is released, the closing claw spring 13 moves the operating rod upward while closing the movable claw 7 against the elasticity of the opening spring 8.
扶持部５が熱電対線を把持したら、位置決めフランジ１
４を摺動し、縦目盛１７ ａ、または縦目盛１７ ｂと

対結合端部の与えられた溶着点への深さと同じくした後
、固定用ビス１６によってフランジ１４を外筒１に固定
する。Once the supporting part 5 grips the thermocouple wire, the positioning flange 1
4, and use the vertical scale 17a or 17b and a scale (not shown) to measure the distance between the thermocouple coupling end 21 and the lower surface of the flange, from the inlet end face of the thin tube 23 to the thermocouple coupling end. After making the depth equal to the given welding point, the flange 14 is fixed to the outer cylinder 1 with fixing screws 16.
この場合、要すればバーニャ目盛１８を併用する。In this case, a vernier scale 18 is also used if necessary.
次に、第３図Ｆに示すように、熱電対線２０を把持した

共に、熱電対の細管内周壁溶着の場合にはその結合端部
２１の真横突出量を考慮して該結合端部が内周壁に当接
するようフランジ１４の横位置を修正する。Next, as shown in FIG. 3F, the outer cylinder 1 is inserted into the thin tube 23 with the clamping part 5 holding the thermocouple wire 20 first, and the lower surface of the flange 14 is placed on the thin tube inlet end surface. In addition, in the case of welding the inner peripheral wall of a thin tube of a thermocouple, the lateral protrusion of the joint end 21 is taken into account to ensure that the joint end is aligned with the inner peripheral wall. The lateral position of the flange 14 is corrected so that it comes into contact with the flange 14.
溝１０ ｂに熱電対線が保持される場合はフランジ１４
が細管入口端面に載置されさえすればその結合端部は細
管底壁２４に当接している。If the thermocouple wire is held in the groove 10b, the flange 14
As long as it is placed on the capillary inlet end face, its joint end will be in contact with the capillary bottom wall 24.
なお、図において細管２３は基板２５上につの下端部が
取付けられ、基板上面が細管２３の底壁２４を形威して
いる場合を特に示している。In addition, the figure particularly shows the case where the capillary tube 23 has its lower end mounted on the substrate 25, and the upper surface of the substrate forms the bottom wall 24 of the capillary tube 23.
上記によって明らかなように、熱電対結合端部２１を細

ランジ１４を基準として想定する以外にないから、フラ
ンジの軸周りに関する扶持部５の相対位置が狂うことは
許されない。As is clear from the above, it is almost impossible to actually see the contact between the thermocouple coupling end 21 and the inner circumferential wall of the capillary tube, and the direction in which the coupling end protrudes is entirely from the flange 14. Since there is no other choice but to assume this as a reference, it is not allowed that the relative position of the supporting portion 5 around the axis of the flange is out of order.
このため、フランジ１４と外筒１とは断面方形の摺動係
合とされ、かつ外筒１の下端テーパー壁２と挾持部５の
爪とは断面楕円形の係合とされ、もって上記相対位置が
一定に保持されている。Therefore, the flange 14 and the outer cylinder 1 are in sliding engagement with each other with a square cross section, and the lower end tapered wall 2 of the outer cylinder 1 and the claw of the clamping part 5 are in an elliptical cross-sectional engagement with each other. The position is held constant.
熱電対結合端部２１が溶着位置に当接したら熱電対線２
０と細管２３間に瞬間的な高電圧をかけ、いわゆるパー
カッション溶接を行なう。When the thermocouple joint end 21 comes into contact with the welding position, the thermocouple wire 2

熱電対結合端部の溶接が終ったら、プッシュ部１１を押
圧して外筒１に対し操作棒４を摺動圧入し、扶持部５を
開く。When the welding of the thermocouple coupling end is completed, the push part 11 is pressed to slide and press the operating rod 4 into the outer cylinder 1, and the support part 5 is opened.
この状態で外筒１を細管２３から僅かに揺さぶりながら
静かに抜出すことによって溶着された熱電対線２０を挾

る。In this state, the welded thermocouple wire 20 can be removed from the groove 10 of the clamping part 5 by gently pulling out the outer cylinder 1 from the thin tube 23 while shaking it slightly, thereby attaching the thermocouple wire to a predetermined location on the inner wall. A thin tube can be obtained by welding.

可能にしたものである。As mentioned above, the present invention has a supporting part consisting of two split claws that can be opened and closed at the tip of the operating rod that slidably penetrates the hollow part of the outer case, and the thermocouple wire is held in the holding part. Insert the tip of the thermocouple wire, with the joint end slightly protruding, into the narrow space through the outer cylinder, and make sure that the joint end is firmly in contact with the required location on the inner wall using the vertical scale of the outer shell. - A thermocouple mounting jig that performs percussion welding, and after welding is completed, the clamping part can be easily detached and removed from the welded thermocouple wire by pressing an operating rod from the outside. This makes it possible to attach a thermocouple to the inner wall of a narrow space, which was conventionally difficult to do using fingers or tweezers.
