Description
【考案の詳細な説明】
本考案は、ナツト受は側のプロジェクションナツト溶接
用電極の構造に関するものである。[Detailed Description of the Invention] The present invention relates to the structure of an electrode for welding a projection nut on the side of the nut receiver.
一般にプロジェクションナツトを溶接する場合は、第１
図に示すように受は側電極１を固定し、ワーク５の穴を
位置決め用のピン２に入れてからプロジェクションナツ
ト３を同じくピン２に入れた後、押え電極４により抑圧
通電して溶接する。Generally, when welding a projection nut, the first
As shown in the figure, the receiver fixes the side electrode 1, inserts the hole in the workpiece 5 into the positioning pin 2, and then inserts the projection nut 3 into the pin 2 as well, and then welds by suppressing current through the presser electrode 4. .
従来、この位置決め用のピン２は、バネにより常時突出
するように付勢され、引込み方向に押された場合は引込
むようになっている。Conventionally, this positioning pin 2 is always urged by a spring so as to protrude, and is retracted when pushed in the retracting direction.
しかしながら、この構造では、ピン２は溶接完了後には
突出するため、ワーク５をそのｉｔ横方向に移動するこ
とができず、ワーク５をピンの高さだけ上方に特に上げ
なければならない。However, in this structure, since the pin 2 protrudes after welding is completed, the workpiece 5 cannot be moved laterally, and the workpiece 5 must be specifically raised upward by the height of the pin.
このことは、プロジェクションナツト溶接工程を自動化
するような場合にもワークを上方に持ち上げる機構が必
要である。This means that even when automating the projection nut welding process, a mechanism for lifting the workpiece upward is required.
本考案はかかる機構を必要としないプロジェクションナ
ツト溶接用電極の提供を目的とする。The present invention aims to provide an electrode for projection nut welding that does not require such a mechanism.
第２図は本考案のｌ実施例をあられすものであるが、電
極基体１０には通電抑圧面９の中央部よりピン２が突出
できるよう支持されており、ピン２ば、バネ６により引
込み方向に付勢されている。FIG. 2 shows an embodiment of the present invention, in which a pin 2 is supported on the electrode base 10 so that it can protrude from the center of the energization suppressing surface 9, and the pin 2 is retracted by a spring 6. biased in the direction.
電極基体１０の内部には空気室７が形成され、空気圧に
よりピン２が突出するようになっている。An air chamber 7 is formed inside the electrode base 10, and the pin 2 is made to protrude due to air pressure.
空気室７には、空気供給口８より空気を供給する。Air is supplied to the air chamber 7 from an air supply port 8.
この電極を使用する場合は、たとえば押え側電極の動き
に同調して、空気供給を制御し、溶接完了時に空気室の
空気圧を抜けば、バネの作用によりピンは引込むからワ
ークの横方向の移動が自由になるのである。When using this electrode, for example, if the air supply is controlled in synchronization with the movement of the presser side electrode, and the air pressure in the air chamber is released when welding is completed, the pin will be retracted by the action of the spring, allowing the workpiece to move laterally. becomes free.
本考案によるプロジェクションナツト溶接用電極によれ
ば、生産工程の自動化の際、ワークを円滑に移動するこ
とができ、上下動の機構は必要としないから、その合理
性により斯界に多大の効果をもたらすものである。According to the projection nut welding electrode according to the present invention, when automating the production process, the workpiece can be moved smoothly and no vertical movement mechanism is required, so its rationality will bring great effects to the industry. It is something.

正面図、第２図は本考案の１実施例をあられす断面図で
ある。FIG. 1 is a front view showing an aspect of projection nut welding, and FIG. 2 is a sectional view showing an embodiment of the present invention.
