Description

【０００１】
【発明の属する技術分野】
本発明は、溶接作業に使用される溶接用ワイヤ送給装置に関するものである。
【０００２】
【従来の技術】
従来の溶接用ワイヤ送給装置は図５と図６に示したような構成であった。
【０００３】
図５は溶接用ワイヤ送給装置を前面から見た図で、３０は溶接用ワイヤ送給装置の側面を覆っているカバー、３１は底面に配置された各部品を搭載するベース、３２は溶接用ワイヤ送給装置の上面を覆っている天板、３３は人が溶接用ワイヤ送給装置を移動させる時に使用する取っ手で天板３２に接合されている。
【０００４】
また、３４は溶接用ワイヤ送給装置の前面を覆っている前パネル、３５はベース３１と天板３２を連結する側板である。カバー３０は開閉することが可能となっている。
【０００５】
図６はカバー３０を取り除き溶接用ワイヤ送給装置を側面から見た図で、３６は溶接用ワイヤ３７が巻かれているスプール３８の回転軸となるスプール軸である。３９はスプール軸３６を固定するスプール取付板、４０は溶接用ワイヤ３７を溶接用トーチ（図示せず）に送給するために駆動源となるモータ、４１はモータ４０の駆動力を溶接用ワイヤ３７に伝えるワイヤ送給部ある。４２は前パネル３４に接合され溶接用ワイヤ送給装置の部品等を入れる箱状の部品ケースである。
【０００６】
【発明が解決しようとする課題】
しかしながら、このような従来の構成の溶接用ワイヤ送給装置では、(１)溶接用ワイヤ３７の送給力を調整するためにワイヤ送給部４１を調整する場合、(２)溶接用ワイヤ３７の消耗によりスプール３８を交換する場合、(３)部品ケース４２に溶接用ワイヤ送給装置の部品等を入れる場合等、上記いずれの場合においても溶接用ワイヤ送給装置の側面を覆っている大型カバー３０を開閉しなければならず、その大きさの強度を保つために質量が重いカバー３０の大きさと質量により開閉作業がやり難いという問題があった。
【０００７】
また、溶接用ワイヤ送給装置を移動させる時に使用する取っ手３３には、ベース３１上に配置されたモータ４０、スプール３８等の全重量物の質量が掛かり、取っ手３３が接合された天板３２、ベース３１と天板３２を連結する側板３５及びベース３１の個々の部品に全重量物の質量を支える強度が必要となる。その結果、天板３２、側板３５及びベース３１の補強構造が必要になり、各部品の質量が重くなるという問題もあった。
【０００８】
したがって本発明は、上記従来の課題を解消し溶接用ワイヤ送給装置のカバーを開閉し易くし、開閉作業労力の低減化を図り、また構造体の各部品の質量を低減することにより可搬性に富んだ溶接用ワイヤ送給装置を提供することを目的とする。
【０００９】
【課題を解決するための手段】
この目的を達成するために、本発明の第１手段は、スプールを後部カバー部で覆い、モータを前部カバー部で覆い、溶接用ワイヤ送給装置全体を後部カバー部と前部カバー部で覆い、後部カバー部に単独で開閉または着脱可能な樹脂製のスプールカバーを設け、前部カバー部に単独で開閉または着脱可能なモータカバーを設けたものである。
【００１０】
この構成により溶接用ワイヤの送給力を調整するためにワイヤ送給部を調整する場合は、前部カバー部に設けられた単独で開閉または着脱可能なモータカバーのみを開けば可能であり、また、溶接用ワイヤの消耗によりスプールを交換する場合は、後部カバー部に設けられた単独で開閉または着脱可能なスプールカバーのみを開けば可能であるので、上記の各動作においてそれぞれの目的に合った小型のカバーのみを開閉すればよいので開閉労力が低減する作用を有する。
【００１１】
また、本発明の第２手段は、スプールを後部カバー部で覆い、モータを前部カバー部で覆い、溶接用ワイヤ送給装置全体を後部カバー部と前部カバー部で覆い、後部カバー部に単独で開閉または着脱可能な樹脂製のスプールカバーを設け、前部カバー部の下側に単独で開閉または着脱可能なモータカバーを設け、前部カバー部の上側に単独で開閉または着脱可能な箱状の部品ケースを設けたものである。
【００１２】
この構成により溶接用ワイヤの送給力を調整するためにワイヤ送給部を調整する場合は、前部カバー部の下側に設けられた単独で開閉または着脱可能なモータカバーのみを開けば可能であり、また、溶接用ワイヤの消耗によりスプールを交換する場合は、後部カバー部に設けられた単独で開閉または着脱可能なスプールカバーのみを開けば可能であり、また、溶接用ワイヤ送給装置の部品等を送給装置内に格納する場合は、前部カバー部の上側に設けられた単独で開閉または着脱可能な部品ケースのみを開けば可能であるので、上記の各動作においてそれぞれの目的に合った小型のカバー、部品ケースのみを開閉すればよいので開閉労力が低減する作用を有する。
【００１３】
また、本発明の第３手段は、第２手段においてモータカバーの上部に平面状なケースベースを設け、ケースベース上を部品ケースがスライドするようにしたものである。
【００１４】
この構成により第２手段の作用に加え箱状の部品ケースが溶接用ワイヤ送給装置の側面よりスライドして出てくるので部品等を格納し易いという作用を有する。
【００１５】
また、本発明の第４手段は、スプールの回転軸となるスプール軸を固定するスプール取付部を底部のベースに接合し、ベース前部にモータを固定し、取っ手となるパイプを上方から下方に伸ばし下部においてパイプとベースを接合し、モータの前方のカバーとなる前パネルとパイプ及びベースと接合し、モータの上方のカバーとなる上パネルを前パネルと接合し、上パネルとスプール取付部を接合したものである。
【００１６】
この構成により重量物であるモータとスプールをスプールに付いてはスプール取付部を介して底部のベースで受け、全重量物の質量が掛かるベースを取っ手を兼ねたパイプにて保持する。また、ベースと前パネル、前パネルと上パネル、上パネルとスプール取付部、スプール取付部とベースの接合によりベースを前パネル、上パネル及びスプール取付部にて保持することになる。更に、前パネルとパイプが接合されているので、取っ手であるパイプを持ち上げた時、全重量物の質量が掛かるベースをパイプとループとなった前パネル、上パネル及びスプール取付部の２つの構造体にて受けるので各部品に掛かる力は低減され、その分個々の部品質量を低減する作用を有する。
【００１７】

BACKGROUND OF THE INVENTION
The present invention relates to a welding wire feeding device used for welding work.
[0002]
[Prior art]
The conventional welding wire feeding device has a configuration as shown in FIGS .
[0003]
FIG. 5 is a view of the welding wire feeding device as viewed from the front , 30 is a cover covering the side surface of the welding wire feeding device, 31 is a base for mounting each component arranged on the bottom surface, and 32 is welding. A top plate 33 covering the upper surface of the wire feeder for welding is joined to the top plate 32 by a handle used when a person moves the wire feeder for welding.
[0004]
Also, 34 is the panel before covering the front surface of the welding wire feeder, 35 is a side plate for connecting the base 31 and the top plate 32. The cover 30 can be opened and closed.
[0005]
FIG. 6 is a side view of the welding wire feeding device with the cover 30 removed, and 36 is a spool shaft serving as a rotation shaft of the spool 38 around which the welding wire 37 is wound. Reference numeral 39 denotes a spool mounting plate for fixing the spool shaft 36, reference numeral 40 denotes a motor serving as a drive source for feeding the welding wire 37 to a welding torch (not shown), and reference numeral 41 denotes a driving force of the motor 40 for welding wire. There is a wire feeding section to be transmitted to 37. Reference numeral 42 denotes a box-shaped component case which is joined to the front panel 34 and holds components of a welding wire feeder.
[0006]
[Problems to be solved by the invention]
However, in the welding wire feeding device having such a conventional configuration, when (1) the wire feeding portion 41 is adjusted to adjust the feeding force of the welding wire 37, (2) the welding wire 37 is adjusted. A large cover that covers the side surface of the welding wire feeder in any of the above cases, such as when the spool 38 is replaced due to wear, or (3) when the parts of the welding wire feeder are placed in the parts case 42, etc. 30 has to be opened and closed, and in order to maintain the strength of the size, there is a problem that the opening and closing operation is difficult due to the size and mass of the cover 30 having a heavy mass.
[0007]
Also, the handle 33 used when moving the welding wire feeding device is loaded with the mass of all heavy objects such as the motor 40 and the spool 38 disposed on the base 31, and the top plate 32 to which the handle 33 is joined. The side plate 35 connecting the base 31 and the top plate 32 and the individual components of the base 31 need to have strength to support the mass of all heavy objects. As a result, a reinforcing structure for the top plate 32, the side plate 35, and the base 31 is required, and there is a problem that the mass of each component becomes heavy.
[0008]
Therefore, the present invention eliminates the above-mentioned conventional problems, makes it easier to open and close the cover of the welding wire feeding device, reduces the labor for opening and closing, and reduces the mass of each component of the structure, thereby making it portable. An object of the present invention is to provide a welding wire feeding device rich in quality.
[0009]
[Means for Solving the Problems]
To achieve this object, the first means of the present invention covers the spool with the rear cover part, the motor with the front cover part, and the entire welding wire feeding device with the rear cover part and the front cover part. The rear cover part is provided with a resin-made spool cover that can be opened and closed independently, and the front cover part is provided with a motor cover that can be opened and closed independently.
[0010]
When adjusting the wire feeding part in order to adjust the feeding force of the welding wire with this configuration, it is possible to open only the motor cover provided on the front cover part that can be opened / closed independently or attached / detached. When replacing the spool due to wear of the welding wire, it is possible to open only the spool cover provided on the rear cover that can be opened / closed independently or attached / detached. Since only a small cover needs to be opened and closed, the opening and closing labor is reduced.
[0011]
Further, the second means of the present invention covers the spool with the rear cover part, covers the motor with the front cover part, covers the entire welding wire feeder with the rear cover part and the front cover part, and covers the rear cover part. A plastic spool cover that can be opened and closed independently is provided, a motor cover that can be opened and closed independently is provided below the front cover part, and a box that can be opened and closed independently is provided above the front cover part. Shaped part case is provided.
[0012]
With this configuration, when adjusting the wire feeding part to adjust the feeding force of the welding wire, it is possible to open only the motor cover that can be opened and closed independently or attached on the lower side of the front cover part. In addition, when replacing the spool due to the consumption of the welding wire, it is possible to open only the spool cover provided on the rear cover that can be opened / closed independently or attached / detached. When storing parts in the feeding device, it is possible to open only the part case that can be opened and closed independently or attached on the upper side of the front cover part. Since it is only necessary to open and close only the small cover and the component case, the opening and closing labor is reduced.
[0013]
According to a third means of the present invention, in the second means, a planar case base is provided above the motor cover so that the component case slides on the case base.
[0014]
With this configuration, in addition to the operation of the second means, the box-shaped component case slides out from the side surface of the welding wire feeding device, so that the components and the like can be easily stored.
[0015]
Further, the fourth means of the present invention is to join a spool mounting portion for fixing a spool shaft serving as a rotation shaft of the spool to the base at the bottom, fix the motor to the front portion of the base, and move the pipe serving as the handle downward from above. Join the pipe and base at the lower part of the stretch, join the front panel and the pipe and base that are the front cover of the motor, join the upper panel that is the upper cover of the motor and the front panel, and connect the upper panel and the spool mounting part. It is joined.
[0016]
With this configuration, a heavy motor and a spool are attached to the spool and received by the base at the bottom via the spool mounting portion, and the base on which the mass of all heavy objects is applied is held by a pipe that also serves as a handle. Further, the base is held by the front panel, the upper panel, and the spool mounting portion by joining the base and the front panel, the front panel and the upper panel, the upper panel and the spool mounting portion, and the spool mounting portion and the base. Furthermore, since the front panel and the pipe are joined, when the pipe, which is the handle, is lifted, the base on which the mass of the entire heavy load is applied is the two structures of the front panel, the upper panel, and the spool mounting portion that become a pipe and a loop. Since it is received by the body, the force applied to each part is reduced, and the mass of each part is reduced accordingly.
[0017]
