摘要： [Objective] To efficiently weld a second tip, which is a noble metal tip, to a first tip with high accuracy.
[Means for Solution] A manufacturing apparatus has a plurality of chuck units (110), each including a chuck (81) for holding a first tip (11), a chuck position adjustment means (90) capable of adjusting the position of a reference center axis (C1) of the chuck (81), and a base (120) which supports the chuck position adjustment means (90). Each of the bases (120) has a shaft (92) coaxial with the reference center axis (C1) of the chuck (81). The bases (120) are rotatably disposed at equal intervals on an imaginary circle of a rotary circular table (101) via the respective shafts (92). The chuck (81) is caused to hold the first tip (11); the position of an actual center axis (C2) of the first tip (11) is measured by image processing, thereby detecting an eccentric error relative to the shaft (92); the chuck position adjustment means (90) is driven for correcting the position of the center axis (C2) of the first tip (11) so as to align the position of the center axis (C2) with the position of the shaft (92), and then a second tip is disposed; and while the chuck unit (110) is rotated about the shaft (92), the outer circumferential edges of the joining end surfaces of the first and second tips are laser-welded.

摘要： Provided is a technique for limiting the radial displacement between a metal shell and an insulator in a spark plug. At the time of manufacturing a spark plug with a metal shell and an insulator, the metal shell and the insulator are assembled together by, while allowing relative positional displacement between the metal shell and the insulator in an axial direction (O-O), limiting relative positional displacement between the metal shell and the insulator in a radial direction intersecting with the axial direction in such a manner that the amount of deviation between an axis of the metal shell and an axis of the insulator becomes less than or equal to a predetermined level.

摘要： A method and an apparatus for manufacturing a spark plug which can form a spark discharge gap with sufficient accuracy. A bending apparatus 51 used in a manufacturing process of the spark plug includes a bending unit 52 having a preliminary bending unit 61 and a main bending unit 71, and a gap adjusting unit 81. The main bending unit 71 including pressing means for pressing a distal end of a ground electrode toward a center electrode, and adjust a relative height position of the distal end of the ground electrode relative to a distal end of the center electrode in an axis line direction. The gap adjusting unit 81 includes gap adjusting means for relatively moving the distal end of the ground electrode relative to the center electrode in a direction substantially perpendicular to the axis line direction, and restricting means for restricting relative movement of the distal end of the ground electrode relative to the center electrode in the axis direction.

摘要： This invention relates to a method and apparatus for making a spark plug, in particular, for making a high-performance spark plug having a center electrode having a firing end made of Pt, Ir, Rh, Pd, Re, Os, Ru or alloy thereof, with its firing end diameter of about 0.3-1.0 mm. One of the embodiments provides a method comprising the steps of: extending a metal strip from an end of the metal shell; positioning a spacer above a firing end of the center electrode; preliminarily bending the metal strip toward the spacer so as to form an arc portion in the metal strip; and then precisely forming a gap-distance between the metal strip and the firing end of the center electrode by applying a force to the metal strip. The method may further include a step of measuring the position of the firing end of the center electrode so as to determine a position for the spacer and/or a step of retrieving the spacer after bending the metal strip so that the gap-distance between the metal strip and the center electrode is adjusted to a required value by referring to a position of the preliminary bent metal strip and the position of the firing end of the center electrode. The invention also provides an apparatus for performing this method.

摘要： A predetermined cross section (55) of a noble metal tip (50) is divided by a vertical line (L) into two half cross sections, which are a first half cross section (60) and a second half cross section (70) different from the first half cross section (60). The first half cross section (60) satisfies Expressions 1 and 2, and the second half cross section (70) satisfies Expressions 3 and 4. h ⁢ 1 / t ≤ 0.2 , Rw ⁢ 1 / Rt ⁢ 1 ≥ 1.03 h ⁢ 2 / t ≤ 0.2 , Rw ⁢ 2 / Rt ⁢ 2 ≥ 1.03
At a welding interface (80), oxidation scale progresses in a "direction away from an axis OL" along side surfaces (63, 73), and changes the progressing direction at the end points (65, 75) so as to progress in a "direction toward the axis OL" along bottom surfaces (62, 72). Therefore, progress of oxidation scale is restrained. Also, since the noble metal tip (50) is held by an engagement portion (45) of a ground electrode (40), separation of the noble metal tip (50) from the ground electrode (40) can be restrained.
