Abstract
Description
本発明はスポット溶接機に係り、詳しくは、主として枠型の大きな被溶接物の縦面を溶接ガンで挟み、作業者が手動で連続的に溶接するスポット溶接機に関する。 The present invention relates to a spot welder, and more particularly, to a spot welder in which a vertical surface of a large frame-shaped workpiece is sandwiched between welding guns and an operator manually welds continuously.
従来から、各種金属の板の結合には２枚の被溶接物を重ねて、上下電極で挟み、加圧、通電して溶接するスポット溶接が用いられ、鉄道車両などのように巨大な被溶接物のスポット溶接には作業者がポータブルガンといわれる溶接ガンを操作して手動で溶接する方法が広く使用されて来た。 Conventionally, spot welding has been used for joining various metal plates by stacking two workpieces, sandwiching them between the upper and lower electrodes, and applying pressure and energization to weld them. For spot welding of objects, a method in which an operator manually welds a welding gun called a portable gun has been widely used.
しかし、この機器ポータブルガンは被溶接物を加圧するエアシリンダと溶接トランスとで一体で構成されている場合が多く、ポータブルガン全体が大きくなり、かなりの重量となる。そこで設備の天井からバランサなどを利用してポータブルガンを吊り下げる方式を用い、重いポータブルガンの重量を軽減して作業者が操作している。また、通電に必要な電線は、吊ったポータブルガンの操作をさらに困難にし、数個所もの溶接打点を溶接する際の、ポータブルガンの移動と溶接は大変な重作業および、手間のかかる作業となっている。 However, in many cases, this device portable gun is integrally formed of an air cylinder that pressurizes an object to be welded and a welding transformer, and the entire portable gun becomes large and has a considerable weight. Therefore, a portable gun is suspended from the ceiling of the facility by using a balancer, etc., and the operator operates it by reducing the weight of the heavy portable gun. In addition, the electric wires required for energization make the operation of the suspended portable gun even more difficult, and the movement and welding of the portable gun when welding several welding points is a very heavy and time-consuming work. ing.
特許文献１、２は、ポータブルガンと称する溶接ガンを吊り下げて作業者が手動により巨大な被溶接物を溶接してきた従来の事例である。 Patent Documents 1 and 2 are conventional examples in which a welding gun called a portable gun is suspended and an operator manually welds a huge workpiece.
このポータブルガンは大別して溶接トランスを分離したタイプ（特許文献３）と一体タイプ（特許文献４）とがあるが、それぞれ、次のような問題がある。 This portable gun is roughly classified into a type in which a welding transformer is separated (Patent Document 3) and an integrated type (Patent Document 4), but each has the following problems.
分離したタイプの場合は溶接トランスを他の場所へ設置している。そのため、ポータブルガンはコンパクトになる一方、溶接トランスから導電ケーブルを介してポータブルガンに通電する必要がある。溶接トランスの二次側のこの導電ケーブルは水冷ケーブルともいわれ、細い銅線の撚り線で構成され、ケーブルの中を冷却水が循環するので、４０ｍｍ程の径となり、重く、剛性の高いケーブルとなっている。そのため吊り下げたポータブルガンの操作が困難な作業となっている。また、経時的な繰り返しの使用により、ケーブルの銅線の断線が発生することもあり、導電ケーブルは消耗品となっている。 In the case of the separated type, the welding transformer is installed elsewhere. Therefore, while the portable gun becomes compact, it is necessary to energize the portable gun from the welding transformer via the conductive cable. This conductive cable on the secondary side of the welding transformer is also called a water-cooled cable, which is composed of a thin copper wire, and the cooling water circulates in the cable, so it has a diameter of about 40 mm and is heavy and highly rigid. It has become. Therefore, it is difficult to operate a suspended portable gun. In addition, the copper wire of the cable may be disconnected due to repeated use over time, and the conductive cable is a consumable item.
一体タイプの場合は溶接トランスと一体で構成されているため、ポータブルガンそのものが大きくなり、かなりの重量となる。その上、溶接トランスへの一次側の電線も必要で、やはり、吊ったポータブルガンの操作が困難な作業となっている。 In the case of the integral type, since it is constructed integrally with the welding transformer, the portable gun itself becomes large and has a considerable weight. In addition, a primary electric wire to the welding transformer is also required, which makes it difficult to operate the suspended portable gun.
以上のような問題を解決して、大きな被溶接物の側面に多数の溶接個所があっても、操作性が良く、効率の良い作業のできるスポット溶接機を提供することを課題とする。 It is an object of the present invention to provide a spot welder that solves the above problems and has good operability and efficient work even when there are a large number of welds on the side of a large workpiece.

本発明は板状のテーブルとその上で溶接ガンとなる加圧通電アームを作業者が操作し、この加圧通電アームで被溶接物を挟み、加圧通電して溶接するスポット溶接機であって、被溶接物の多数の側面のスポット溶接個所は、被溶接物を載置したまま、操作性の良い加圧通電アームを移動し連続的に溶接できる作業効率の良い溶接が可能である。また、ポータブルガンに必要な、消耗品である導電ケーブルや溶接ガンの電気配線を無くすことができる。 The present invention is a spot welding machine in which an operator operates a plate-like table and a pressurizing energizing arm serving as a welding gun on the plate table, sandwiches an object to be welded by the pressurizing energizing arm, and performs welding by applying energizing pressure.

図１〜図７は本発明に係るスポット溶接機の実施例であり、側面をスポット溶接する側面導電板と上部から吊るされた加圧通電アームを具備したスポット溶接機である。 1 to 7 show an embodiment of a spot welder according to the present invention, which is a spot welder provided with a side conductive plate for spot welding a side surface and a pressurizing energizing arm suspended from the top.
添付する図を用いて実施例を説明すると、次のとおりである。 The embodiment will be described with reference to the accompanying drawings.
本発明のスポット溶接機の実施例１を図１に正面図、図２に図１を横方向から見た右側面図を示す。
図１、図２に示すように、本発明のスポット溶接機（１）は、側面に溶接個所が多数ある大きな被溶接物（Ｗ）を長いテーブル（３０）に載置する。この溶接機はテーブル（３０）の上部、例えば設備の天井（２）などから吊り具（１０）で吊るされた加圧通電アーム（４）を具備しており、加圧通電アーム（４）は被溶接物（Ｗ）の側面である縦面の多数のスポット溶接個所を連続的に溶接するものである。
FIG. 1 is a front view of a spot welder according to a first embodiment of the present invention, and FIG. 2 is a right side view of FIG.
As shown in FIGS. 1 and 2, the spot welder (1) of the present invention places a large workpiece (W) having a large number of welding points on the side surface on a long table (30). This welding machine includes a pressurization energizing arm (4) suspended from a top of a table (30), for example, a ceiling (2) of equipment, by a hoisting tool (10). A large number of spot welds on the vertical surface, which is the side surface of the workpiece (W), are continuously welded.
具体的に本発明の溶接機の構成に従い、その作業の手順を説明すると、最初に側面に溶接個所が多数ある被溶接物（Ｗ）をテーブル（３０）上に載置する。このとき溶接個所のある側面をテーブル（３０）の端部に直角に立設した銅を材料とする側面後導電板（７）に突き当て当接する。 Specifically, according to the construction of the welding machine of the present invention, the work procedure will be described. First, the workpiece (W) having a number of welding points on the side surface is placed on the table (30). At this time, the side surface with the welded portion is abutted against and abutted against the side surface rear conductive plate (7) made of copper, which is erected at right angles to the end of the table (30).
次に、作業者は加圧通電アーム（４）を被溶接物（Ｗ）の側面の決められた溶接個所に移動する。この加圧通電アーム（４）には溶接トランスは不要で、導電ケーブルや電気配線もなく、そのため、従来のポータブルガンに比べると操作は容易である。加圧通電アーム（４）の昇降は吊り具（１０）としてエアシリンダとかスプリングバランサなどで構成し上下させる。また図１では紙面の前後方向の移動に直動ガイド（１５）を利用し、簡便に操作できるようにした実施例である。 Next, the operator moves the pressurizing energizing arm (4) to a predetermined welding location on the side surface of the workpiece (W). This pressurization energizing arm (4) does not require a welding transformer, and there is no conductive cable or electric wiring, and therefore, operation is easier compared to a conventional portable gun. The pressurizing and energizing arm (4) is moved up and down by using an air cylinder or a spring balancer as a lifting tool (10). FIG. 1 shows an embodiment in which a linear motion guide (15) is used to move the paper in the front-rear direction so that the operation can be easily performed.
側面のスポット溶接は、作業者が加圧通電アーム（４）の位置を決め、溶接スイッチをＯＮに操作すると、加圧通電アーム（４）のエアシリンダ（１２）が作動する。加圧通電アーム（４）の二つのアーム（８Ａ、８Ｂ）は導電材料からなり、回転軸（２０）を支点として回転するのでエアシリンダ（１２）の作動により、被溶接物（Ｗ）に対し、開閉する。すなわち、被溶接物（Ｗ）の側面を側面後導電板（７）、絶縁板（１４）、側面導電板（５）と共に二つのアーム（８Ａ、８Ｂ）で挟み込み、溶接チップ（１１）で加圧する。図３が加圧通電し溶接するときの状態を示している。テーブル（３０）の下に配置した溶接トランス（１６）の一方の電極は接続銅板（１７）を介し側面導電板（５）に接続し、他方の電極は接続銅板（１８）を介し側面後導電板（７）に接続している。
実施例１では二つのアーム（８Ａ、８Ｂ）の開閉をエアシリンダ（１２）としたが、この代替として、油圧シリンダやモータ駆動機構での方法も可能である。（図示せず）
In spot welding on the side, when the operator determines the position of the pressurization energization arm (4) and operates the welding switch to ON, the air cylinder (12) of the pressurization energization arm (4) is activated. The two arms (8A, 8B) of the pressurizing energizing arm (4) are made of a conductive material and rotate around the rotating shaft (20), so that the air cylinder (12) is actuated to the work piece (W). Open and close. That is, the side surface of the workpiece (W) is sandwiched between the two rear arms (8A, 8B) together with the rear side conductive plate (7), the insulating plate (14), and the side conductive plate (5), and added with the welding tip (11). Press. FIG. 3 shows a state when welding is carried out under pressure. One electrode of the welding transformer (16) arranged under the table (30) is connected to the side conductive plate (5) via the connection copper plate (17), and the other electrode is conductive on the rear side via the connection copper plate (18). Connected to the plate (7).
In the first embodiment, the air cylinder (12) is used to open and close the two arms (8A, 8B). Alternatively, a method using a hydraulic cylinder or a motor drive mechanism is also possible. (Not shown)
被溶接物（Ｗ）を加圧後、前もって登録された溶接条件の電流が溶接トランス（１６）の一方の電極と接続銅板（１７）を介し接続した側面導電板（５）から図４に示すような可撓性導電体（１９）を経由しアーム（８Ｂ）先端の溶接チップ（１１）から被溶接物（Ｗ）へと流れスポット溶接が１打点完了する。
この動作を繰り返し、側面のスポット溶接を連続して実施し完了する。図４に可撓性導電体（１９）の装着した実施例を示すが、可撓性導電体（１９）は呼称オンス銅板といわれ、０．２ｍｍ程の薄い銅板を重ね合わせ結合したもので弾力性があり、用途により種々の形状が使用される。
平面部のスポット溶接の事例は従来、数多く、種々ある（特許文献５、６，７参照）。本発明ではスポット溶接が難しい縦面の溶接方法を課題としてその改善策を提案している。そのため被溶接物（Ｗ）を載置するテーブル（３０）は絶縁性の材質とするのが良く、平面部の溶接を実施する特許文献５、６、７のように銅板を用いずとも良い。
After pressurizing the work piece (W), the current under the welding conditions registered in advance is shown in FIG. 4 from the side conductive plate (5) connected to one electrode of the welding transformer (16) via the connecting copper plate (17). Through such a flexible conductor (19), the spot welding is completed at one point by flowing from the welding tip (11) at the tip of the arm (8B) to the workpiece (W).
This operation is repeated, and the side surface spot welding is continuously performed and completed. FIG. 4 shows an embodiment in which a flexible conductor (19) is mounted. The flexible conductor (19) is called an ounce copper plate, and is formed by overlapping and bonding thin copper plates of about 0.2 mm. Various shapes are used depending on the application.
Conventionally, there are many and various examples of spot welding of the flat surface (see Patent Documents 5, 6, and 7). In the present invention, a method for improving a vertical surface welding method that is difficult to perform spot welding is proposed. Therefore, the table (30) on which the work piece (W) is placed is preferably made of an insulating material, and it is not necessary to use a copper plate as in Patent Documents 5, 6, and 7 in which the flat surface is welded.
次に、加圧通電アーム（４）が一体のときの実施例２を図５に示す。この実施例では一体アーム（２２）にエアシリンダ（２３）が搭載されこのエアシリンダ（２３）のピストンロッドの先端に装着された溶接チップにより被溶接物（Ｗ）が挟持され、もう一方の溶接チップ（１１）により、加圧力が被溶接物（Ｗ）へ付加される。側面導電板（５）からの電流を加圧側の溶接チップ（１１）に伝達するため、ここでも、新たな可撓性導電体（２４）が用いられる。 Next, FIG. 5 shows a second embodiment in which the pressure energizing arm (4) is integrated. In this embodiment, an air cylinder (23) is mounted on the integral arm (22), and the work piece (W) is clamped by the welding tip attached to the tip of the piston rod of the air cylinder (23), and the other welding is performed. The tip (11) applies pressure to the work piece (W). Again, a new flexible conductor (24) is used to transmit the current from the side conductor plate (5) to the welding tip (11) on the pressure side.
図６、７は被溶接物（Ｗ）が巨大な鉄道用の車両などの場合の実施例３を示し、図１から図５に示す実施例１、２とは吊り具（１０）が異なり、吊り具としてスプリングバランサを活用している。
Ａ面（３１）とは別に、Ｂ面（３２）のスポット溶接を実施するときは、側面導電板（５）、絶縁板（１４）、側面後導電板（７）と加圧通電アーム（４）などを更にもう一式配備するか、もしくは加圧通電アーム（４）を移動する方式にすれば、大きな被溶接物（Ｗ）を移動せずに、他の面の溶接も可能となる。
6 and 7 show Example 3 in the case of a railway vehicle or the like having a huge work piece (W), and the hanging tool (10) is different from Examples 1 and 2 shown in FIGS. A spring balancer is used as a lifting tool.
When spot welding of the B surface (32) is performed separately from the A surface (31), the side conductive plate (5), the insulating plate (14), the side rear conductive plate (7), and the pressure energizing arm (4) ), Etc., or a system in which the pressurized energizing arm (4) is moved, the other surface can be welded without moving the large workpiece (W).
主に枠型の大きな被溶接物の側面個所のスポット溶接が連続的にでき、被溶接物を載置したままで、ケーブルのない溶接ガンで容易に作業のできる溶接機として活用できる。また、ポータブルガンに付随する消耗品である導電ケーブルや電気配線が不要である。 It can be used as a welding machine that can perform spot welding mainly on the side surface of a large frame-shaped workpiece, and can easily work with a welding gun without a cable while the workpiece is placed. In addition, there is no need for conductive cables and electrical wiring that are consumables associated with the portable gun.
