Description

  The present invention relates to a remote controller having a function of changing welding conditions of a welder, and a welding apparatus having a welder, a welding torch, and a remote controller.

  In consumable electrode type arc welding such as CO2 welding and MAG welding (hereinafter referred to as CO2 / MAG welding), items that are frequently adjusted to perform appropriate welding include output current and output voltage output by the welding machine. By adjusting the output current and output voltage to make the welding conditions appropriate, the welding result is improved and the work efficiency is improved.

  When performing welding, the welding operator adjusts the output current and the output voltage according to the thickness of the metal to be welded, the welding posture, and the like. Even when the welding operator performs welding at a location away from the welding machine, it is desirable that the output current and output voltage can be adjusted at the location where the welding operator is welding and at the hand of the welding operator. .

  A welding device used in CO2 / MAG welding has a welding machine, a wire feeding device, a welding torch, and a remote controller. The welding machine and the wire feeding device are connected by a cable. The wire feeding device and the welding torch are connected by a cable. A remote controller for setting welding conditions is often connected to a wire feeder from the viewpoint of workability of a welding operator.

  Analog type welding machines generally have a volume (rotary variable resistor) for adjusting output current and output voltage in the welding machine itself. Digital type welding machines generally have a jog dial for adjusting output current and output voltage in the welding machine itself. However, many workers use a remote control that can adjust the welding conditions at hand because welding is performed at a location away from the welding machine.

  The conventional remote controller for the welding machine is large to some extent so that the welding operator can easily handle it. In addition, in order to make the remote control strong, it has a structure for protecting the volume, and the size of the remote control is also large from such a viewpoint.

  In a situation where an operator uses a remote control at hand at a place where welding is performed, the remote control is often placed on the ground or in the vicinity of the welding work table. For this reason, there is a possibility that the operator will step on the remote control, or a heavy object may be dropped on the remote control. Therefore, in order to withstand trampling and heavy objects, the strength of the remote control itself is increased by adding a protective member for the volume, and the remote control itself is made sufficiently large.

  In addition, the volume itself is large enough to be wrapped by a human hand so that a welding operator can adjust the output current and output voltage by operating the volume while wearing gloves. Therefore, the size of the remote controller having a volume also increases.

  In recent years, remote controllers for welding machines include not only analog remote controllers configured with analog volumes or the like, but also digital remote controllers having a digital display, a jog dial, and the like. Note that the digital remote controller is sufficiently large for reasons such as securing strength, as with the analog remote controller.

  Also, in TIG welding that does not use a welding wire that is a consumable electrode and therefore does not use a wire feeding device, the welding machine and remote controller are connected with a cable, and the remote controller is brought to the hand of the welding operator. There is a case. In CO2 / MAG welding, it is common to connect a remote controller to a wire feeder. On the other hand, in TIG welding, since a wire feeding device is not used, the remote controller is connected to the welding machine. Therefore, the length of the cable connected to the remote controller is longer in the case of TIG welding than in the case of CO2 / MAG welding.

  In TIG welding, since only the welding current is adjusted as the welding condition, changing the welding condition is relatively simple, and the remote controller can be configured to have one volume.

  In addition, when the remote controller is not used, the remote controller may be attached to the wire feeder, and a wire feeder having a configuration in which the remote controller is detachable is known (see, for example, Patent Document 1). .

  FIG. 5 shows an example of the above-described remote controller and wire feeder, and shows a state where the remote controller is attached to the wire feeder 17. The remote control includes a remote control case 11, an output current adjustment volume 12, an output voltage adjustment volume 13, a guard 14, a control cable 15, and a connector 16. The guard 14 is a protective member for protecting the output current adjustment volume 12 and the output voltage adjustment volume 13. The remote control case 11 is connected to a wire feeding device 17 via a control cable 15 and a connector 16.

  A method of using the remote controller configured as described above will be described. A welding operator performs welding under certain welding conditions. And based on the welding result, the adjustment operation which adjusts a welding current and a welding voltage so that it may become appropriate welding conditions is performed using the remote control as shown in FIG. 5 connected to the wire feeder. Thereafter, the welding operation is performed again, and the adjustment operation is performed again as necessary. As described above, the welding operator determines appropriate welding conditions while alternately performing the welding operation and the adjustment operation. The remote controller is used for adjustment work.

  In addition, when performing a welding operation, a welding operator performs welding by holding a welding torch with one hand and a welding light shielding surface that is a light shielding tool for protecting eyes from the light of the arc with the other hand. Further, when performing the adjustment work, the welding worker places a welding torch or a welding light shielding surface on a work table, the ground, or the like, and performs the adjustment by holding the remote control.

Japanese Utility Model Publication No.59-140079

  The conventional remote controller is large in size so that the welding operator can operate the remote controller while wearing gloves and can be easily placed on the wire feeder.

  Since the remote control is large in size, the remote controller is operated while being placed on the wire feeder, or is operated in a state where it is placed near the work place.

  In addition to the above, the remote control according to the present invention includes a current adjusting unit for adjusting a welding current output by the welding machine, and a voltage adjusting unit for adjusting the welding voltage output by the welding machine. It has two adjustment parts.

  The welding apparatus of the present invention is a welding apparatus comprising a welding machine, a welding torch, a remote controller having a function of changing welding conditions, and a welding light shielding surface that is a light shielding tool for protecting eyes during welding.

FIG. 2 is a diagram showing an external appearance of the remote controller 20. FIG. 3 is a view showing a state in which the remote controller 20 is attached to the welding torch 19. FIG. 4 is a view showing a state in which the remote controller 20 is attached to the handle 10 of the welding light shielding surface 9.

  In FIG. 1, the welding apparatus includes a welding machine 18, a wire feeding device 17, a welding torch 19, a remote controller 20, and a welding light shielding surface 9. The wire feeding device 17 is connected to the welding machine 18. The welding torch 19 and the remote controller 20 are connected to the wire feeder 17.

  In FIG. 2, the remote controller 20 has a case portion 1, a current adjustment volume 2, a voltage adjustment volume 3, a connector 4, a control cable 5, and a fixing hole 6.

  In the present embodiment, the case portion 1 shows an example of a square shape. The case portion 1 has a smaller shape than the handle portion 8 of the welding torch 19 shown in FIG. That is, the area of the maximum projection surface of the case portion 1 is smaller than the area of the maximum projection surface of the handle portion 8 of the welding torch 19. In addition, although the case part 1 may be comprised with a resin material, in order to improve robustness, it is good also as metal.

  The current adjustment volume 2 is for adjusting the welding current output from the welding machine 18. The voltage adjustment volume 3 is for adjusting the welding voltage output from the welding machine 18. The current adjustment volume 2 and the voltage adjustment volume 3 are disposed on the same surface of the rectangular case 1.

  The connector 4 is a connection part for connecting the remote controller 20 to the wire feeding device 17. The control cable 5 is a cable for electrically connecting the current adjustment volume 2 and voltage adjustment volume 3 provided in the case portion 1 to the connector 4. The control cable 5 is connected to the case portion 1 from a surface different from the surface on which the current adjustment volume 2 and the voltage adjustment volume 3 are arranged, among the surfaces of the case portion 1. As described above, one end of the control cable 5 is connected to the case portion 1, and the other end of the control cable 5 is connected to the connector 4.

  The fixing hole 6 is a hole for attaching the remote controller 20 to the welding torch 19 or the handle 10 of the welding light shielding surface 9. There are two fixing holes 6 on the surface of the case portion 1 that does not contact the surface on which the current adjustment volume 2 and the voltage adjustment volume 3 are arranged, that is, on the back surface of the rectangular case portion 1. Is provided. The fixing hole 6 has an elongated rectangular shape so that a binding band 7 which will be described later, which is an example of a fixing member, can be passed therethrough.

  The operation of the remote controller 20 configured as described above will be described.

  As shown in FIG. 3, the remote controller 20 is attached to the welding torch 19. Specifically, for example, the remote controller 20 is disposed on the side surface of the welding torch 19, and the binding band 7, which is an example of a fixing member, is passed through each of the two fixing holes 6 provided in the case portion 1 of the remote controller 20. The welding torch 19 and the remote controller 20 are bundled simultaneously. In this way, the remote controller 20 can be attached to the welding torch 19. And the remote control 20 can be removed from the welding torch 19 by removing the binding band 7. That is, the remote controller 20 can be attached to and detached from the welding torch 19.

  The fixing member is not limited to the binding band 7, and rubber, tape, string, or the like may be used. Alternatively, a part having a shape that allows the remote controller 20 to be fixed to the welding torch 19 with one touch, for example, a spring-like metal that covers the welding torch 19 may be used.

  As described above, by attaching the remote controller 20 to the welding torch 19, even if the welding operator holds the welding torch 19 or the welding light shielding surface 9, the welding operator directly operates the remote controller 20 at hand. Welding conditions can be changed. That is, the welding operator operates both the current adjustment volume 2 and the voltage adjustment volume 3 of the remote controller 20 with the finger of the hand holding the welding torch 19 while holding the welding torch 19 and the welding light shielding surface 9. be able to. The remote controller 20 is attached to the welding torch 19 at a position where the current adjustment volume 2 and the voltage adjustment volume 3 can be operated with a finger of the hand holding the welding torch 19. Thereby, compared with the past, the stop time of the welding operation for operating the remote controller 20 can be reduced, and the complexity of the switching work between the welding torch 19 and the welding light shielding surface 9 and the remote controller 20 can be reduced. , Work efficiency of welding work is improved.

  Note that the remote controller 20 of the present embodiment has a shape smaller than the handle portion 8 of the welding torch 19. Therefore, it can be attached to the welding torch 19, and even when attached to the welding torch 19, the operation of the welding torch 19 is not hindered.

  Since the remote controller 20 has a small shape, the remote controller 20 may be attached not to the handle portion 8 of the welding torch 19 but to the handle 10 of the welding light shielding surface 9 as shown in FIG. The attachment method and the effects of the attachment are the same as when the remote controller 20 is attached to the handle portion 8 of the welding torch 19. That is, even if the welding operator holds the welding torch 19 and the welding light shielding surface 9, both the current adjustment volume 2 and the voltage adjustment volume 3 of the remote controller 20 can be used with the finger of the hand holding the handle 10 of the welding light shielding surface 9.

On the other hand, when the remote controller 20 is attached to the welding torch 19, it is easy for the operator to perform the operation sensuously, which is excellent in terms of workability.

  Further, in CO2 / MAG welding, appropriate welding cannot be performed unless both the welding current and the welding voltage are appropriate. According to the present embodiment, both the welding current and the welding voltage can be operated with only the finger of one hand while holding the welding torch 19 and the welding light shielding surface 9, and the workability is extremely high. Is excellent.

  Note that although the example in which the welding torch 19 is connected to the wire feeding device 17 has been described, the welding torch 19 may be connected to the welding machine 18.

  As described above, the remote controller 20 has a smaller shape than the handle portion 8 of the welding torch 19 and can be attached to or detached from the welding torch 19 or the welding light shielding surface 9. Therefore, even when the remote controller 20 breaks down, the remote controller 20 can be easily replaced, and the maintenance is excellent. In particular, the maintainability is excellent as compared with a case where the function of the remote controller 20 is provided inside the welding torch 19.

  The remote controller 20 has a shape smaller than the handle portion 8 of the welding torch 19. Therefore, it can be attached not only to the welding torch 19 and the welding light shielding surface 9 but also to a thin column near the welding operator, the pocket of the welding operator himself, and the like. Therefore, unlike a conventional large remote controller, the degree of freedom of the location of the remote controller 20 and the degree of freedom of carrying the remote controller 20 are improved. Therefore, workability can be further improved compared to the case of using a conventional remote controller.
