Description

本発明は、アーク溶接用のトーチに付着したスパッタを短時間で除去するためのスパッタ除去装置に関するものである。   The present invention relates to a spatter removing apparatus for removing spatter adhering to a torch for arc welding in a short time.

アーク溶接用のトーチは、周知のように、溶接ワイヤの周囲にノズルが形成され、該ノズルから炭酸ガス、アルゴンガス等のシールドガスで溶接部分をシールドすることにより溶接部分の酸化が防止されるようにしているが、作業中にスパッタがこのノズルの先端部およびノズル内面に付着し、その付着量が増すとシールドガスの吹き出しに悪影響を及ぼすことから、従来では作業者がノズルの先端部や内面を切刃や金属ブラシによって擦ってスパッタを離脱させ、除去するようにしていた。しかし、これでは作業能率が悪い欠点があるとともに、ノズルに擦りキズが付き、スパッタが一層付着し易くなるという問題がある。なお、スパッタの付着を防ぐためにノズルに薬品を塗布したり、或いはスパッタが付着し難いカーボン製のノズルを使用することも知られているが、そのようにしても十分に防ぐことができなかった。   As is well known, a torch for arc welding has a nozzle formed around a welding wire, and the welded portion is shielded from the nozzle with a shielding gas such as carbon dioxide gas or argon gas to prevent oxidation of the welded portion. However, since spatter adheres to the tip of the nozzle and the inner surface of the nozzle during the operation, and the amount of adhesion increases, the blowout of the shielding gas is adversely affected. The inner surface was rubbed with a cutting blade or a metal brush to remove the spatter and remove it. However, this has the disadvantage that the working efficiency is poor, and there is a problem that the nozzles are scratched and spatter adheres more easily. In addition, it is known that chemicals are applied to the nozzle in order to prevent adhesion of spatter, or a carbon nozzle that does not easily adhere to spatter is used, but even in such a case, it could not be sufficiently prevented. .

一方、下記特許文献１に示されたスパッタ掃除装置は、空圧回路に設けられた電磁弁を開閉することにより空圧シリンダに断続的に圧縮空気を送ることで該空圧シリンダに設けられたハンマーを振動させ、該ハンマーに溶接トーチを当てることにより、ノズルに付着したスパッタを振動で離脱、除去しようとするものである。   On the other hand, the sputter cleaning device shown in the following Patent Document 1 is provided in the pneumatic cylinder by intermittently sending compressed air to the pneumatic cylinder by opening and closing an electromagnetic valve provided in the pneumatic circuit. By oscillating the hammer and applying a welding torch to the hammer, the spatter adhering to the nozzle is separated and removed by vibration.

特開平４−９４８７５号公報JP-A-4-94875

ところが、従来のように振動によりスパッタを離脱させるだけでは、ノズル内部のガス噴出口に付着しているスパッタが排出され難く、掃除に時間がかかるという問題があった。特にノズルの形状が先端部で細く奥部で広がっているものでは、内部のスパッタが一層排出され難いといった問題がある。
本発明はこのような問題点を解決しようとするものである。 However, there is a problem that it is difficult to discharge the spatter adhering to the gas outlet inside the nozzle by simply separating the spatter by vibration as in the prior art, and it takes time for cleaning. In particular, when the shape of the nozzle is narrow at the tip and wide at the back, there is a problem that internal spatter is more difficult to be discharged.
The present invention is intended to solve such problems.

そのために本発明に係る溶接トーチのスパッタ除去装置は、押しボタンが押圧されることにより給気バルブを開作動させる起動機構と、該起動機構の給気バルブから圧縮空気が供給されることによりピストンが進退動してハンマーが繰り返し打撃され、該ハンマーに当接させた溶接トーチを激しく振動させ該溶接トーチの内面に付着したスパッタをその振動により離脱させる振動発生機構と、該起動機構の給気バルブから溶接トーチに圧縮空気が供給されることにより溶接トーチ内のスパッタを排出させる圧縮空気供給管路とからなることを特徴とする。   For this purpose, the spatter removing device for a welding torch according to the present invention includes an activation mechanism that opens an air supply valve when a push button is pressed, and a piston that is supplied with compressed air from the air supply valve of the activation mechanism. A vibration generating mechanism in which the hammer is repeatedly struck and vibrated vigorously to vibrate the welding torch in contact with the hammer, and the spatter adhering to the inner surface of the welding torch is released by the vibration, and the air supply of the starting mechanism It is characterized by comprising a compressed air supply conduit for discharging spatter in the welding torch when compressed air is supplied from the valve to the welding torch.

また、上記起動機構は、振動発生機構に高圧の圧縮空気を送給する第１の給気バルブと、これよりも低圧の圧縮空気を圧縮空気供給管路に送給する第２の給気バルブとを備えており、押しボタンが押圧されることにより両給気バルブが開作動するようにしたことを特徴とする。
このように、高圧の圧縮空気を振動発生機構に送給することにより、ピストンがハンマーを強力に叩打し得るようになり、溶接トーチを激しく振動させることができる。また、低圧大容量の圧縮空気を圧縮空気供給管路を経て溶接トーチに送給することにより、ノズル内のスパッタが直ぐに排出されるようになる。 The starting mechanism includes a first air supply valve for supplying high-pressure compressed air to the vibration generating mechanism, and a second air supply valve for supplying compressed air having a lower pressure to the compressed air supply line. And both supply valves are opened when the push button is pressed.
In this way, by supplying high-pressure compressed air to the vibration generating mechanism, the piston can strike the hammer strongly, and the welding torch can be vibrated vigorously. Further, by supplying low-pressure and large-capacity compressed air to the welding torch via the compressed air supply line, the spatter in the nozzle is immediately discharged.

また、上記振動発生機構は、太径部と細径部とからなるピストンがシリンダ内に進退動可能に設けられ、該ピストンの細径部の外周面と該シリンダの内周面との間に空気流入空間が形成され、該シリンダの一端部に該ピストンの太径部と相対する加圧室が形成され、該シリンダの他端部に該ピストンの細径部が突出する大気開放空間が形成されているとともに、ハンマーの基部が該ピストンの突出端と相対するように配置され、該ピストン中には一端が前記加圧室と連通し他端が該ピストンの外周に開口している通気路が形成され、該開口は該ピストンの進退動時に前記空気流入空間または大気開放空間と連通するように開設され、前記空気流入空間に流入した圧縮空気が該通気路を通して断続的に前記加圧室に流入することにより該ピストンが進退動し前記ハンマーの基部が該ピストンによって繰り返し打撃されるようにしたことを特徴とする。
このように、圧縮空気によってピストンを直に進退動させ、該ピストンによりハンマーが打激されることにより、激しい強力な振動を得ることができる。 The vibration generating mechanism includes a piston having a large-diameter portion and a small-diameter portion so that the piston can be moved forward and backward in the cylinder, and between the outer peripheral surface of the small-diameter portion of the piston and the inner peripheral surface of the cylinder. An air inflow space is formed, a pressure chamber facing the large diameter portion of the piston is formed at one end of the cylinder, and an open air space in which the small diameter portion of the piston protrudes at the other end of the cylinder And an air passage in which one end of the hammer is connected to the pressurizing chamber and the other end is open to the outer periphery of the piston. The opening is opened so as to communicate with the air inflow space or the atmosphere release space when the piston moves forward and backward, and the compressed air flowing into the air inflow space intermittently passes through the air passage. The piston by flowing into There wherein the base of the advancing and retreating to the hammer has to be repeatedly struck by the piston.
Thus, intense powerful vibration can be obtained by moving the piston directly forward and backward by the compressed air and hammering the piston.

本発明によれば、ハンマーの強力な打撃によって溶接トーチを激しく振動させることができるので、スパッタを離脱させることが容易であると同時に、離脱したスパッタが圧縮空気により直ぐに排出されるので、スパッタを溶接トーチから短時間できれいに除去することができる。   According to the present invention, since the welding torch can be vibrated vigorously by powerful hammering, it is easy to disengage the spatter, and at the same time, the spatter that has been separated is immediately discharged by the compressed air. It can be removed cleanly from the welding torch in a short time.

In addition, the push button 21 and the hammer 48 are formed in a cylindrical shape with a synthetic resin having impact resistance. Reference numeral 9 denotes a tray that is detachably provided on the lower edge of the case body 11 in order to receive the spatter 8 that is detached from the welding torch 1 and falls.

図２に示したように、装置本体１０には、起動機構２０および振動発生機構４０が構成される。１３は圧縮空気の供給源と連結されるマニホールド、１４，１５は該マニホールドに設けられた圧力調整弁で、一方の圧力調整弁１４の２次側空気圧は４．５〜５．０Kgｆ／ｃｍ２に設定され、他の圧力調整弁１５の２次側空気圧はこれよりも低圧の２．５〜２．８Kgｆ／ｃｍ２に設定される。 As shown in FIG. 2, the apparatus main body 10 includes an activation mechanism 20 and a vibration generation mechanism 40. 13 is a manifold connected to a supply source of compressed air, 14 and 15 are pressure regulating valves provided in the manifold, and the secondary air pressure of one pressure regulating valve 14 is 4.5 to 5.0 kgf / cm 2. The secondary air pressure of the other pressure regulating valve 15 is set to 2.5 to 2.8 kgf / cm 2 , which is lower than this.

次に起動機構２０を説明する。起動機構２０は、圧力調整弁１４の２次側と配管２２を介して連通する弁室２３を形成し、該弁室内に弁体２４を進退動自在に設けることにより第１の給気バルブ２５を構成し、該弁体２４に前記押しボタン２１を軸２６を介して直結している。なお、２４ａは弁室２３内に設けられ弁体２４を閉方向に付勢しているバネ状弾性体である。該給気バルブ２５の２次側には通気路２７と通気路２８が分岐形成され、通気路２７は区画室２９に連通し、該区画室には上下動可能に往復動体３０が設けられている。３１は前記圧力調整弁１５の２次側と配管３２を介して連通するように形成された弁室で、該弁室内に弁体３３を進退動自在に設けることにより第２の給気バルブ３４を形成する。なお、３３ａは弁室３１内に設けられ弁体３３を閉方向に付勢しているバネ状弾性体である。そして、該弁体３３の下方延長端を前記往復動体３０の上面と対向させている。そして、該給気バルブ３４の２次側は前記圧縮空気供給管路７に連通させている。   Next, the activation mechanism 20 will be described. The activation mechanism 20 forms a valve chamber 23 that communicates with the secondary side of the pressure regulating valve 14 via a pipe 22, and a valve body 24 is provided in the valve chamber so as to be capable of moving forward and backward. The push button 21 is directly connected to the valve body 24 via a shaft 26. Reference numeral 24a denotes a spring-like elastic body that is provided in the valve chamber 23 and biases the valve body 24 in the closing direction. A vent path 27 and a vent path 28 are branched from the secondary side of the air supply valve 25. The vent path 27 communicates with a compartment 29, and a reciprocating body 30 is provided in the compartment so as to be movable up and down. Yes. 31 is a valve chamber formed so as to communicate with the secondary side of the pressure regulating valve 15 via a pipe 32, and a second air supply valve 34 is provided by providing a valve body 33 in the valve chamber so as to be movable forward and backward. Form. Reference numeral 33a denotes a spring-like elastic body that is provided in the valve chamber 31 and biases the valve body 33 in the closing direction. The lower extension end of the valve body 33 is opposed to the upper surface of the reciprocating body 30. The secondary side of the air supply valve 34 communicates with the compressed air supply line 7.

このため、押しボタン２１が押されると、弾性体２４ａに抗して弁体２４が移動して第１の給気バルブ２５が開かれ、高圧の圧縮空気が通気路２７と通気路２８に流入する。そして、通気路２７に流入した圧縮空気は往復動体３０を押し上げ、該往復動体３０はさらに弾性体３３ａに抗して弁体３３を押し上げることから、第２の給気バルブ３４も同時に開かれ、低圧の圧縮空気が圧縮空気供給管路７に供給されるようになる。   For this reason, when the push button 21 is pressed, the valve body 24 moves against the elastic body 24 a to open the first air supply valve 25, and high-pressure compressed air flows into the air passage 27 and the air passage 28. To do. Then, the compressed air flowing into the air passage 27 pushes up the reciprocating body 30 and the reciprocating body 30 pushes up the valve body 33 against the elastic body 33a, so that the second air supply valve 34 is also opened simultaneously. Low pressure compressed air is supplied to the compressed air supply line 7.

また、振動発生機構４０は、シリンダ４１が水平に配置され、該シリンダ４１内に太径部４２ａと細径部４２ｂとからなるピストン４２が進退動可能に設けられ、該シリンダ４１の略中間部に通気口４３が形成され、細径部４２ｂの外周面と該シリンダ４１の内周面との間に空気流入空間４４が形成され、該空気流入空間４４が通気口４３を介して前記通気路２８と連通する。該シリンダ４１の一端部には該ピストン４２の太径部４２ａと相対する加圧室４５が形成される。４６はシリンダ４１の一端部を包囲して加圧室４５を形成するために固着された蓋部材である。また、シリンダ４１の他端部にはピストン４２の細径部４２ｂが突出する大気開放空間４７が形成されている。５０は前記ハンマー４８の軸４９を進退動自在に支持している軸受部材で、これによって該軸４９の内端部に形成された基部５１がピストン４２の突出端と相対するように配置される。なお、該軸受部材５０には大気開放空間４７を外部と連通させる通気口５２が開設される。   The vibration generating mechanism 40 includes a cylinder 41 disposed horizontally, and a piston 42 including a large diameter portion 42 a and a small diameter portion 42 b provided in the cylinder 41 so as to be capable of moving forward and backward. The air inlet 43 is formed in the air inlet space 44 between the outer peripheral surface of the small diameter portion 42 b and the inner peripheral surface of the cylinder 41, and the air inlet space 44 is connected to the air passage through the air vent 43. Communicate with 28. A pressurizing chamber 45 is formed at one end of the cylinder 41 so as to face the large-diameter portion 42 a of the piston 42. A cover member 46 is fixed to surround one end of the cylinder 41 to form the pressurizing chamber 45. The other end of the cylinder 41 is formed with an open air space 47 from which the small diameter portion 42b of the piston 42 protrudes. Reference numeral 50 denotes a bearing member that supports the shaft 49 of the hammer 48 so as to be able to move forward and backward. By this, a base portion 51 formed at the inner end portion of the shaft 49 is disposed so as to face the protruding end of the piston 42. . The bearing member 50 is provided with a vent 52 that allows the atmosphere open space 47 to communicate with the outside.

また、ピストン４２中には一端が前記加圧室４５と連通し他端が該ピストンの外周に開口５４する通気路５３が形成される。なお、開口５４はピストン４２が進退動することにより前記空気流入空間４４または大気開放空間４７と連通する位置に開設される。   Further, a vent passage 53 is formed in the piston 42 such that one end communicates with the pressurizing chamber 45 and the other end opens 54 on the outer periphery of the piston. The opening 54 is opened at a position communicating with the air inflow space 44 or the atmosphere release space 47 as the piston 42 moves forward and backward.

このように構成したスパッタ除去装置では、図２に破断線で示したように、溶接トーチ１をその先端を下にして押しボタン２１およびハンマー４８に押し付けることにより、第１の給気バルブ２５が開き、高圧の圧縮空気が通気口４３から空気流入空間４４に流入し、該圧縮空気の空圧がピストン４２の太径部４２ａを押圧することにより該ピストン４２を図中左方向に移動させる。そうすると図３に示したように該ピストンの開口５４が空気流入空間４４に連通するようになり、該空気流入空間４４の圧縮空気は該開口５４から通気路５３を通って加圧室４５に流入するようになり、該加圧室４５の空圧を上昇させる。このため図４に示したように加圧室４５の空圧によりピストン４２は図中右方向に移動し、該ピストン４２の突出端（図中右端）が基部５１を叩打しハンマー４８を突出させる。そのとき、該ピストン４２の開口５４が大気開放空間４７と連通することで、加圧室４５の空気が開口５４から該大気開放空間４７に抜け、該加圧室４５は大気圧になる。するとまた空気流入空間４４に流入した高圧の圧縮空気がピストン４２の太径部４２ａを押圧することにより該ピストン４２を図中左方向に移動させ、図２の状態となり、図３の状態を経て図４に示した状態になる。このため高圧の圧縮空気によりピストン４２は高速で激しく進退動し、ハンマー４８の基部が該ピストンによって繰り返し打撃され、該ハンマー４８に押し当てられた溶接トーチ１を激しく振動させる。このため該溶接トーチ１のノズル１ａ内面および先端部に付着しているスパッタを即座に離脱させることができる。   In the spatter removing apparatus configured as described above, as shown by a broken line in FIG. 2, the first air supply valve 25 is moved by pressing the welding torch 1 against the push button 21 and the hammer 48 with the tip thereof down. The compressed air of high pressure flows into the air inflow space 44 from the vent 43 and the air pressure of the compressed air presses the large diameter portion 42a of the piston 42, thereby moving the piston 42 in the left direction in the figure. Then, as shown in FIG. 3, the piston opening 54 communicates with the air inflow space 44, and the compressed air in the air inflow space 44 flows into the pressurizing chamber 45 from the opening 54 through the air passage 53. The air pressure in the pressurizing chamber 45 is increased. Therefore, as shown in FIG. 4, the piston 42 moves rightward in the figure due to the air pressure in the pressurizing chamber 45, and the protruding end (right end in the figure) of the piston 42 strikes the base 51 to cause the hammer 48 to protrude. . At this time, the opening 54 of the piston 42 communicates with the atmosphere opening space 47, so that the air in the pressurizing chamber 45 passes through the opening 54 to the atmosphere opening space 47, and the pressurizing chamber 45 becomes atmospheric pressure. Then, the high-pressure compressed air flowing into the air inflow space 44 presses the large-diameter portion 42a of the piston 42 to move the piston 42 leftward in the figure, and the state shown in FIG. 2 is obtained, and the state shown in FIG. The state shown in FIG. 4 is obtained. For this reason, the piston 42 is vigorously moved back and forth at high speed by the high-pressure compressed air, the base portion of the hammer 48 is repeatedly hit by the piston, and the welding torch 1 pressed against the hammer 48 is vibrated vigorously. For this reason, the sputter | spatter adhering to the nozzle 1a inner surface and front-end | tip part of this welding torch 1 can be made to detach | leave immediately.

また、押しボタン２１に溶接トーチ１を押し付けることにより、第１の給気バルブ２５と同時に第２の給気バルブ３４が開くことから、低圧大容量の圧縮空気が圧縮空気供給管路７に供給され、該圧縮空気はシャトルバルブ５からホース２内を通って溶接トーチ１に供給され、振動により離脱したスパッタを該溶接トーチ１のノズル１ａ内から外に排出させ、該スパッタ８を受皿９中に落下させる。このため、ロボットアームの移動範囲にこのスパッタ除去装置を配置しておけば、該ロボットの作動で該溶接トーチ１を押しボタン２１およびハンマー４８に押し付けさせるだけで、該溶接トーチ１内に付着したスパッタを非常に短時間（２〜３秒間で可能）で除去することができ、溶接の作業性を大幅に向上させることができる。   Further, by pressing the welding torch 1 against the push button 21, the second air supply valve 34 opens simultaneously with the first air supply valve 25, so that low pressure and large capacity compressed air is supplied to the compressed air supply line 7. Then, the compressed air is supplied from the shuttle valve 5 through the hose 2 to the welding torch 1, the spatter separated by vibration is discharged from the nozzle 1 a of the welding torch 1, and the sputter 8 is put into the tray 9. Let fall. For this reason, if this spatter removing device is arranged in the movement range of the robot arm, the welding torch 1 is attached to the welding torch 1 only by pressing the welding torch 1 against the push button 21 and the hammer 48 by the operation of the robot. Spatter can be removed in a very short time (possible in 2 to 3 seconds), and welding workability can be greatly improved.

なお、この実施形態は、起動機構２０として２つの給気バルブ２５，３４を備えたものを示したが、両バルブを一体的なものとし、圧縮空気供給管路７および振動発生機構４０に同時に高圧大容量の圧縮空気が送給されるようにしてもよい。   In this embodiment, the activation mechanism 20 includes the two air supply valves 25 and 34. However, both the valves are integrated, and the compressed air supply line 7 and the vibration generating mechanism 40 are simultaneously provided. High-pressure and large-capacity compressed air may be supplied.
