本発明は、複数の部材をろう接する際にろう接材料を介

ろう接用治具に関するものである。[Detailed Description of the Invention] (Objective of the Invention) (Industrial Application Field) The present invention is directed to positioning a plurality of members by holding a plurality of members facing each other via a soldering material when soldering a plurality of members. This relates to a brazing jig.
（従来の技術）
たとえば、電子管用金属部品等の製造に際して、第４図

状態で、炉内で加熱し、熱によりろう接材料３を焔かし
ながら、シリンダ１．２をろう接させる。(Prior Art) For example, when manufacturing metal parts for electron tubes, etc., as shown in FIGS. 4 and 5, cylinders 1 with two different diameters are
, 2 through the soldering material 3, two cylindrical holding parts 4.5 that fit with each cylinder 1, 2 are integrally provided on the flange part 6 in descending order of diameter. Using a brazing jig 7, a cylinder 1 with a large diameter, a brazing material 3 formed in a ring shape according to the shape of the joint part, and a cylinder 2 with a small diameter are sequentially attached to the brazing jig 7. :1N and positioned, and then heated in a furnace while being pressed by the pressure weight 8, and the cylinder 1.2 is brazed while the soldering material 3 is ignited by the heat.
ここで、第６図に示すように、ろう接の後には、熔ｔノ

ろ）援用治具７に接触する可能性がある。Here, as shown in FIG. 6, after soldering, a pool 9 of the soldering material 3 that has protruded from between the cylinders 1 and 2 is formed due to the melting, and the soldering material 3 that has protruded into this pool 9 is b) There is a possibility of contact with the support jig 7.
ところで、一般的な４５０〜１０００℃程度の高温で使

材料３と結合するのを阻止するための酸化皮膜（酸化り

７の表面に酸化皮膜を形成していない場合は、熔けたろ
う核材料３とろう接用治具７が金属的な反応を起こし、
ろう援用治具７の第６図にＡで示す部分に金属拡散して
、シリンダ１．２とろう接用治具７が接合してしまう。By the way, stainless steel material is used for the general brazing jig 7 that is used at high temperatures of about 450 to 1000°C, but this is because the surface of the brazing jig 7 is made of melted brazing material 3. This is because it is easy to form an oxide film (oxidation film) to prevent bonding with the solder.If an oxide film is not formed on the surface of the soldering jig 7, the melted solder core material 3 and the brazing jig 7 cause a metallic reaction,
Metal diffuses into the portion of the brazing aid jig 7 shown by A in FIG. 6, and the cylinder 1.2 and the brazing jig 7 are joined together.
ろう接用治具７の、表面に酸化皮膜を形成したものを使
用すると、この金属拡散を阻止でき、シリンダ１．２と
ろう接用治具７の接合がほとんど発生しなくなる。If a brazing jig 7 with an oxide film formed on its surface is used, this metal diffusion can be prevented, and joining between the cylinder 1.2 and the brazing jig 7 will hardly occur.
（発明が解決しようとする問題点）

問題があり、この他にも、ろう接用治具アは、使用時に
高温となるため、機械的な強度が低下し、変形を起こし

具の熱容量も大きくなり、多くのろう接用治具７を連続

という問題があった。(Problems to be Solved by the Invention) However, in the case of the brazing jig 7 made of stainless steel material, the oxidized film deposited on the surface has a weak mechanical bond and has a short lifespan. Peeling is likely to occur. If the oxide film peels off partially during assembly work or other use, there is a problem that the brazing jig 7 will join to the cylinder 1.2. Because the cylinder sometimes reaches high temperatures, its mechanical strength decreases and deformation occurs easily, and there is also wear when the cylinder 1.2 is attached and detached, so there is a problem that its lifespan is short. Furthermore, stainless steel has a high specific gravity, so the heat capacity of the brazing jig is also large, and when many brazing jigs 7 are used continuously, the brazing circle equipment used also has a high mechanical strength. In addition, there is a problem in that expensive equipment is required in terms of thermal efficiency.
本発明は、このような点に鑑みなされたもので、ろう接
する部材とろう援用治具の接合を効果的に阻止しようと
するものである。The present invention has been made in view of these points, and is intended to effectively prevent the joining of a member to be soldered to a brazing aid jig.

形成するものである。(Means for Solving the Problems) The present invention relates to a brazing jig that holds a plurality of members facing each other via a brazing core material and positions both members when soldering a plurality of members. At least the portion of the brazing jig that comes into contact with the brazing core material is made of a ceramic material.

，２をろう接させるちのである。Note that the three examples are shown in FIGS. 1 to 3, and the wax horizontal use 11, 12, 13 of each example is
Similar to the example shown in FIGS. 4 and 5, two cylinders 1.2 with different diameters are connected to each other by soldering material F.
13 is used for holding and positioning, and two cylindrical holding parts 4°5 into which each cylinder 1 and 2 are fitted are integrated on the 7 flange part 6 in order of increasing diameter. The cylinder 1 with a large diameter, the brazing core material 3 formed in a ring shape according to the shape of the joint, and the cylinder 2 with a small diameter are sequentially fitted and positioned, and then a cylinder 1 for pressurization is fitted. The cylinder 1 is heated in a furnace while being pressed by the weight 8, and the brazing core material 3 is melted by the heat.
, 2 are soldered together.

、１２．１３の寿命も長くなる。In this way, the brazing aid jigs 11 and 12 of any embodiment
．． Even if 13 is used, the brazing core material 3 is the brazing aid jig 11.
12.13, bonding phenomena such as metal diffusion of the brazing core material 3 are prevented, thereby causing the cylinders 1, 2 and the soldering jig 11.12
．． 13 is not joined, and furthermore, cylinders 1 and 2
When the cylinder 1.2 is attached to and removed from the brazing jig 11.12.13, the cylinder 1.2 makes sliding contact only with the ceramic part of the brazing jig 11.12.13, but the ceramic material is different from stainless steel etc. Te 217! Since the coefficient is significantly small, the @ theory of cylinder 1°2 becomes easy, and this also makes it possible to easily connect cylinder 1.2 and brazing jig 11.12.
Since no excessive force is applied to both of the brazing jig 11, the quality of the brazed cylinders 1 and 2 is stable.
, 12.13 will also have a longer lifespan.
そして、第１図のろう援用治具１１の場合、１序が鉄の

ック材料の比熱１．０７と小さくなるので、加熱炉等の
ろう接円の設備を、機械的な強度及び熱効率の面から安
価に作ることができ、加熱時の機械的な強度低下も少な
く、変形の心配も無い。In the case of the brazing aid jig 11 shown in Fig. 1, the specific gravity of the ceramic material is 3.0 compared to the specific gravity of iron, which is 7.8, and the heat capacity is 0.3 to 0.6. In contrast, the specific heat of ceramic materials is as low as 1.07, so equipment for brazing circles such as heating furnaces can be manufactured at low cost in terms of mechanical strength and thermal efficiency, and there is no decrease in mechanical strength during heating. There is no need to worry about deformation.

０を作ることがＣきるので、治具の製造が容易になる。In the case of the brazing jig 13 shown in Fig. 3, instead of using the sintering method, thermal spraying, physical vapor deposition (PVD) such as vacuum evaporation, sputtering, and ion blating, or chemical vapor deposition is used. Ceramic material coating l112 by method (CVD method) etc.
Since it is possible to make 0, manufacturing of the jig becomes easy.

料の組合わせが望ましい。In addition, in the case of the brazing aid jig 12 shown in FIG. 2, since the metal support 16 and the ceramic cylinder 17 are combined, it is desirable to use a combination of metal and ceramic materials that have similar coefficients of thermal expansion. In the case of the soldering jig 13, when making the coating 20 of ceramic material thicker than about 70 μm, it is similarly desirable to use a combination of metal and ceramic material that have similar thermal coefficients.
