この発明は、例えばリンク等の可動部材を取付ける方法
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of attaching a movable member, such as a link.

を提供しようとするものである。Projections 12, 12 are formed on the opposing side surfaces, respectively, and protrude inwardly from each other. The protrusions 12, 12 are inserted into the through hole 13 of the movable member 10 to form a pivot. In reality, the movable member 10 is interposed within both sides of the movable member 10, and the through hole 1 of the movable member 10 is
Protrusions 12, 12 are formed by punching or the like from the outside of each side facing the three parts, and are pivotally supported. However, as pin joints are used in ordinary link devices, this method is applied to very small cases, for example, when the diameter of the through hole 13 is 17rrln or less, and therefore has the following disadvantages. have. That is, the protrusion 12
, 12 and the through hole 13 is difficult, and as a result, the movement of the movable member 10 becomes impossible or cannot be performed smoothly. Also, the thickness of each member 10, 11 is equal to the thickness of the through hole 13.
Similarly, in the case of 1 Tm or less, the protrusions 12, 12 are inevitably
Since the insertion depth into the through hole 13 is also on the order of microns,
Merely protruding by external force is not reliable. In other words, if the insertion depth of the protrusions 12, 12 is increased to increase reliability, an unnecessary load will be added to the movement of the movable member 10, as described above, and if the insertion depth is made smaller, the support of the movable member 10 will be weakened. Become. The present invention aims to eliminate such drawbacks and to provide a method for attaching a movable member by welding a protrusion formed on the attaching member so that the movable member can be attached more reliably.
以下、この発明の一実施例を第２図を参照して説明する
。An embodiment of the present invention will be described below with reference to FIG.
２０は、透孔２１を有する可動部材、２２、２ｊ２は対
向する側面に突起部２３、２３を夫々有するコ字状の取
付部材である。20 is a movable member having a through hole 21, and 22 and 2j2 are U-shaped mounting members having protrusions 23 and 23 on opposing sides, respectively.
突起部２３、２３は、予め形成しておいても良ιル、あ

を溶着する。The protrusions 23, 23 may be formed in advance, or may be formed by external force after the movable member 20 is placed between its sides. The insertion depth of the protrusions 23, 23 into the through hole 31 is such that the movable member 20 is
Hold it down to the extent that it does not move away from 22. Now, in this way, both the integrated members 20 and 22, 22 are placed on a suitable base, and the protrusion 23 of one of them is irradiated with the laser beam 25 focused by the condenser lens 24, Both protrusions 23, 23

２の溶着状態を検知しながら行うことが望ましい。This welding work using the laser beam 25 has the advantage that it can be performed in a non-contact manner and that the processing time can be completed on the order of Msec. Furthermore, adjustment of processing points, processing energy, etc. can be made extremely easily using the optical system, which has the advantage of automation and labor saving. Of course, the role of the pivot can be performed more reliably than in the conventional case where a protrusion simply formed by an external force is used as the pivot. In addition, when irradiating the laser beam 25, lead wires 27 and 28 are connected to the mounting members 22 and 22 at one end, respectively, to a meter 26 for measuring a low resistance value.
By connecting the other end side, the mounting members 22, 2
It is desirable to perform this while detecting the welding state in step 2.
また、取付部材２２としてコ字状のものを用いて説明し
たが、例えば、夫々突出部を有する１対の部材を用いて

けるようにしても良い。Although the description has been made using a U-shaped mounting member 22, for example, a pair of members each having a protrusion may be used, and both protrusions of the member may be inserted into the through hole 21 of the movable member 20. However, the movable member may be attached by welding the protrusion.

。Alternatively, the structure may be such that only one protrusion is welded. Further, the present invention is not limited to a method for attaching links, but is of course sufficiently effective as a method for attaching other movable members. In this invention, the movable member is temporarily pivotally supported by a protrusion formed on the mounting member, and then the movable member is attached by welding the protrusion with a laser beam. This eliminates unnecessary movement of the movable member as in the past. It is now possible to reliably pivot the movable member without adding load or weakening the support.
