Description

本発明は、回転可能なスポット溶接機、特に載置台にスポット溶接機の電源・制御部分が戴置されている回転可能なスポット溶接機に関する。   The present invention relates to a rotatable spot welder, and more particularly to a rotatable spot welder in which a power supply / control part of a spot welder is placed on a mounting table.

従来、数万アンペアの大電流が必要なスポット溶接機は重量が重くかつ大型であり、そのため定置式がほとんどであった(例えば、特許文献1参照。)。定置式の場合、溶接機をほとんど動かすことがないため、かつ大型であるため場所を広くとっていた。   Conventionally, spot welders that require a large current of tens of thousands of amperes are heavy and large in size, and are therefore mostly stationary (see, for example, Patent Document 1). In the case of the stationary type, the welding machine is hardly moved, and since it is large in size, a large space has been taken.

そこで、場所を広くとらず、省スペース化を目的として、小型で、軽量のトランスが開発されている(例えば、特許文献2〜5参照。)。   Therefore, a compact and lightweight transformer has been developed for the purpose of saving space without taking up a large space (see, for example, Patent Documents 2 to 5).

しかし、前記特許文献2〜5は小型で、軽量のトランスが示されているだけで、当該小型かつ軽量のトランスをどのように使用して、省スペース化を図るかについては示されていない。   However, Patent Documents 2 to 5 only show a small and lightweight transformer, but do not show how to use the small and lightweight transformer to save space.

特開2002−239746号公報(図1)JP 2002-239746 A (FIG. 1) 特開2004−200458号公報([0008])Japanese Patent Laying-Open No. 2004-200458 ([0008]) 特開平6−36948号公報([0005])JP-A-6-36948 ([0005]) 特開平6−36949号公報([0007]、[0008])JP-A-6-36949 ([0007], [0008]) 特開平7−116857号公報([0001])JP-A-7-116857 ([0001])

そこで、本発明は、数万アンペアの大電流が必要なスポット溶接機の装置の省スペース化を図ることを目的とする。   SUMMARY OF THE INVENTION An object of the present invention is to save space in a spot welding machine that requires a large current of tens of thousands of amperes.

前記目的を達成するため、本発明の回転可能なスポット溶接機は、
支持部材に回転軸が固定部材により固設され,当該回転軸の上部にスポット溶接機の電源・制御部分を戴置する第1の載置台が固設され,当該回転軸の下部に第2の載置台が固設され,当該第1の載置台の下部及び当該第2の載置台の上部にコの字型に給電バーが設置され,当該第1の載置台の下部の給電バーの先端部分にアームが設けられ,当該アームの上部に加圧機構が設けられ,当該アームの先端部分にチップホルダーが設けられ,当該チップホルダーの先端部にチップが設けられ,当該第2の載置台の上部に設置された給電バーの先端部分にチップホルダーが設けられ,当該チップホルダーの先端部にチップが設けられていることからなる。
In order to achieve the above object, the rotatable spot welder of the present invention comprises:
A rotating shaft is fixed to the support member by a fixed member, a first mounting table for mounting a power source / control part of the spot welder is fixed to the upper portion of the rotating shaft, and a second mounting portion is fixed to the lower portion of the rotating shaft. A mounting table is fixedly installed, a power supply bar is installed in a U-shape at the lower part of the first mounting table and at the upper part of the second mounting table, and the tip of the power feeding bar at the lower part of the first mounting table An arm is provided, a pressure mechanism is provided at an upper portion of the arm, a tip holder is provided at a tip portion of the arm, a tip is provided at a tip portion of the tip holder, and an upper portion of the second mounting table. The tip holder is provided with a tip holder at the tip of the power supply bar, and the tip is provided with the tip at the tip of the tip holder.

又、前記スポット溶接機の電源・制御部分がトランス、電源、及びタイムコントローラであることからなる。   Further, the power source / control part of the spot welder is a transformer, a power source, and a time controller.

さらに、前記電源・制御部分が小型かつ軽量であることからなる。   Further, the power source / control part is small and light.

本発明は、支持部材に回転軸が固設されているので、ワークの溶接が終了した場合、回転軸によりスポット溶接機を回転させ、支持部材の側へ移行することが出来る。そのため、省スペース化を図ることが出来るものである。   In the present invention, since the rotation shaft is fixed to the support member, when the welding of the workpiece is completed, the spot welding machine can be rotated by the rotation shaft and moved to the support member side. Therefore, space saving can be achieved.

本発明の実施の形態の例を図面にしたがって説明する。   An example of an embodiment of the present invention will be described with reference to the drawings.

図1は回転可能なスポット溶接機の側面図である。
支持部材2、たとえば壁に回転軸4が固定部材3,3’により固設されている。
FIG. 1 is a side view of a rotatable spot welder.
A rotating shaft 4 is fixed to a support member 2, for example, a wall, by fixing members 3 and 3 '.

当該回転軸4の上部にスポット溶接機1の電源・制御部分6を戴置する第1の載置台(フレーム)5が固設されている。電源・制御部分6はトランス、電源、タイムコントローラからなる。トランスは背景技術で述べた小型かつ軽量のトランスを使用するのであるが、本発明において使用するトランスを含む電源・制御部分6は、愛知産業(株)が製造、販売しているもので、特に、重量が約30kgで縦約340mm、幅約450mm、長さ約900mmのものを使用するのが最も好適である。   A first mounting table (frame) 5 on which the power source / control part 6 of the spot welding machine 1 is mounted is fixed on the rotating shaft 4. The power supply / control section 6 includes a transformer, a power supply, and a time controller. The transformer uses the small and lightweight transformer described in the background art. The power source / control part 6 including the transformer used in the present invention is manufactured and sold by Aichi Sangyo Co., Ltd. It is most preferable to use one having a weight of about 30 kg, a length of about 340 mm, a width of about 450 mm, and a length of about 900 mm.

小型かつ軽量のトランスを使用すれば、電源・制御部分6全体が小型かつ軽量化し、第1の載置台5に当該電源・制御部分6を戴置することが出来る。   If a small and lightweight transformer is used, the entire power / control part 6 can be made small and light, and the power / control part 6 can be placed on the first mounting table 5.

回転軸4の下部に第2の載置台7が固設され,当該第1の載置台5の下部及び当該第2の載置台7の上部に、かつ回転軸4に接するようにコの字型に給電バー8が設置されている。   A second mounting table 7 is fixed to the lower portion of the rotating shaft 4, and is U-shaped so as to be in contact with the lower shaft of the first mounting table 5 and the upper portion of the second mounting table 7. A power supply bar 8 is installed in the main body.

第1の載置台5の下部の給電バー8の先端部分にアーム9が設けられ、当該アーム9の上部に加圧機構(スライド、シリンダー)10が設けられ、さらに当該アーム9の先端部分にチップホルダー11が設けられており、当該チップホルダー11の先端部にチップ12が設けられている。   An arm 9 is provided at the tip of the power supply bar 8 below the first mounting table 5, a pressure mechanism (slide, cylinder) 10 is provided at the top of the arm 9, and a tip is provided at the tip of the arm 9. A holder 11 is provided, and a tip 12 is provided at the tip of the tip holder 11.

第2の載置台7の上部に設置された給電バー8の先端部分にチップホルダー11’が設けられ,当該チップホルダー11’の先端部にチップ12’が設けられている。 A tip holder 11 ′ is provided at the tip of the power supply bar 8 installed on the upper part of the second mounting table 7, and a tip 12 ′ is provided at the tip of the tip holder 11 ′.

図2は、スポット溶接機が回転し、支持部材側まで移行した状態を示す平面図である。
スポット溶接機が、ワークを溶接する役割を終えた際、このままではスペースを広くとるので回転軸4によりスポット溶接機1を回転させ、一方側(たとえば左側)の支持部材(例えば壁)2の方へ、又は他方側(たとえば右側)の支持部材(例えば壁)2の方へと移行し、支持部材2迄移行させる。このことによりスペースを非常に狭くすることが出来る。矢印は回転方向を示すものである。
FIG. 2 is a plan view showing a state in which the spot welder rotates and moves to the support member side.
When the spot welder finishes the role of welding the workpiece, the space is increased as it is, so that the spot welder 1 is rotated by the rotating shaft 4, and the support member (eg, wall) 2 on one side (eg, left side) is rotated. Or the other side (for example, the right side) of the support member (for example, the wall) 2 is shifted to the support member 2. This can make the space very narrow. The arrow indicates the direction of rotation.

回転可能なスポット溶接機の側面図である。It is a side view of a rotatable spot welder. スポット溶接機が回転し、支持部材側まで移行した状態を示す平面図である。It is a top view which shows the state which the spot welder rotated and it moved to the supporting member side.
