以下本考案の一実施例を添付図面に基づいて詳述する。 図1において、スリーブヨーク10は、軸部10aが中空をなし、先端にはジ ョイントヨーク10bが設けられており、軸部10aの内面には軸方向に沿って スプライン10cが形成されている。軸部10aのスリーブヨーク側の開口端は 、図示のように孔10d、10eと同心的且つ段差をなして拡径されており、孔 10dの開口端には、プラグ11が溶着固定されている。 An embodiment of the present invention will be described below in detail with reference to the accompanying drawings. In FIG. 1, the sleeve yoke 10 has a hollow shaft portion 10a, and a shaft portion 10a at the tip. A joint yoke 10b is provided, and a joint yoke 10b is provided on the inner surface of the shaft portion 10a along the axial direction. A spline 10c is formed. The opening end of the shaft portion 10a on the sleeve yoke side is As shown in the figure, the diameter is enlarged concentrically with the holes 10d and 10e and with a step difference. A plug 11 is welded and fixed to the open end of 10d.
【0009】 プラグ11は、図2に示すように厚肉の円板状をなし、その外径は孔10eよ りも僅かに小径且つ孔10dよりも僅かに大径をなしており、周面11aの一側 半分11bは、全周に亘り面取りされてテーパ面とされており、小径部の外径は 、孔10dよりも僅かに小径とされている。かかるプラグ11は、低炭素鋼の板 材を機械加工して形成されている。[0009] The plug 11 has a thick disk shape as shown in FIG. 2, and its outer diameter is similar to that of the hole 10e. The hole also has a slightly smaller diameter and a slightly larger diameter than the hole 10d, and one side of the circumferential surface 11a. The half 11b is chamfered over the entire circumference to form a tapered surface, and the outer diameter of the small diameter portion is , the diameter is slightly smaller than that of the hole 10d. The plug 11 is made of a low carbon steel plate. It is formed by machining material.
【0010】 このプラグ11は、プロジェクション溶接法によりスリーブヨーク10に溶着 される。即ち、図3に示すように溶接機12の一方の円筒状の電極13にスリー ブヨーク10の軸部10aを嵌合させて機械的に支持すると共に電気的に接続し 、更にスリーブヨーク10の開口端10dの角10d’にプラグ11のテーパ面 11bを全周に亘り当接(図2)せ、当該プラグ11の外面に溶接機12の他方 の円柱状の電極14を当接させ、且つ所定の加圧力Pで圧接させる。この時スリ ーブヨーク10の孔10eにカラー15を嵌挿して孔10d、10e内にプラグ 11及び電極14を同心的に正確に位置決めする。0010 This plug 11 is welded to the sleeve yoke 10 by projection welding. be done. That is, as shown in FIG. 3, one cylindrical electrode 13 of the welding machine 12 is The shaft portion 10a of the block 10 is fitted to mechanically support it and to electrically connect it. , and a tapered surface of the plug 11 at the corner 10d' of the open end 10d of the sleeve yoke 10. 11b over the entire circumference (Fig. 2), and the other side of the welding machine 12 is placed on the outer surface of the plug 11. The cylindrical electrodes 14 are brought into contact with each other and pressed together with a predetermined pressing force P. At this time pickpocket Insert the collar 15 into the hole 10e of the tube yoke 10, and insert the plug into the holes 10d and 10e. 11 and electrode 14 are precisely positioned concentrically.
【0011】 次に、電極13、14間に溶接電流を通電してスリーブヨーク10の孔10d の開口端にプラグ11のテーパ面11bを全周に亘り溶着する。このときの溶接 条件は、溶接電流I=40000A、通電時間T=16サイクル(=16/60 秒)で、2サイクル(=2/60秒)休止、または、溶接電流I’=44000 A、通電時間T’=16サイクルで、2サイクル休止、を3回繰り返して行なう 。この通電制御は、例えば、サイリスタにより行なう。また、電極14の加圧力 Pは、P=1500kgとする。尚、スリーブヨーク10及びプラグ11等のワ ークは、例えば、石油ベンジンで洗浄して脱脂する。[0011] Next, a welding current is applied between the electrodes 13 and 14 to form the hole 10d of the sleeve yoke 10. The tapered surface 11b of the plug 11 is welded around the entire circumference to the open end of the plug 11. Welding at this time The conditions are welding current I = 40000A, energization time T = 16 cycles (=16/60 seconds), pause for 2 cycles (=2/60 seconds), or welding current I'=44000 A. Conduct energization time T' = 16 cycles, pause for 2 cycles, and repeat 3 times. . This energization control is performed by, for example, a thyristor. In addition, the pressing force of the electrode 14 P is assumed to be P=1500 kg. Note that the sleeve yoke 10, plug 11, etc. The tank is degreased by cleaning it with petroleum benzene, for example.
【0012】 これによりプラグ11は、テーパ面11cがスリーブヨーク10の孔10dの 開口端に全周に亘り溶着され、液密に閉塞される。0012 This allows the plug 11 to have its tapered surface 11c aligned with the hole 10d of the sleeve yoke 10. It is welded around the entire circumference of the open end and closed in a liquid-tight manner.
