Description

  The present invention relates to an arc welding torch cleaner that removes spatter attached to a gas shielded arc welding torch used when performing gas shielded arc welding.

Conventionally, gas assembly arc welding such as MAG welding and MIG welding has been used when assembling automobile parts and the like. As shown in FIG. 7, an arc welding torch 50 used for gas shielded arc welding includes a substantially bullet-shaped contact tip 55 through which a solid wire is fed, and a cylindrical tip holder that holds the base of the contact tip 55. 51, a cylindrical shield nozzle 52 disposed so as to enclose the contact chip 55 and the chip holder 51, and a nozzle holder 53 to which the shield nozzle 52 and the chip holder 51 are attached. In gas shielded arc welding, a large current is passed through a solid wire that is continuously fed through a contact tip 51 to generate (discharge) an arc between the solid wire and a member to be welded. In this welding method, the solid wire and the member to be welded are melted by the generated heat to weld the member to be welded. When welding is performed, an inert gas such as CO ² or argon is supplied from a gas supply port 51 a formed in the chip holder 51 in order to prevent blowholes from being generated due to contact between the welding location and air. Then, the inert gas is supplied from the tip of the shield nozzle 52 to the welding location to prevent contact between the welding location and air. The shield nozzle 52 prevents inactive gas from diffusing and reliably supplies the inert gas to the welding location, and is indispensable for gas shielded arc welding.

  During welding, spatter, which is fine particles of molten metal, is generated and scattered from the welding location. As shown in FIG. 7, when the spatter 99 accumulates at the tip of the shield nozzle 52 or the tip of the contact tip 55, the flow of the inert gas in the shield nozzle 52 becomes worse. Then, the supply of the inert gas to the welding location becomes insufficient, and blow holes are generated, resulting in poor welding.

  Therefore, an electrode cleaning tool as shown in Patent Document 1 has been proposed. This electrode cleaning tool has a structure in which a coil spring is attached to the tip of a rotating cylindrical holder, and the rotating coil spring is inserted between the shield nozzle 52 and the contact tip 55 so that the shield nozzle 52 And an apparatus for removing the spatter 99 adhering to the tip of the contact chip 55.

When the spatters 99 adhering to the shield nozzle 52 adhere to each other, the adhering spatters 99 form a ring shape as shown in FIG. In this way, when the ring-shaped sputter 99 is generated, the ring-shaped spatter is removed by removing the spatter 99 adhering to the tip of the shield nozzle 52 and the contact tip 55 with the electrode cleaning tool disclosed in Patent Document 1. 99 are stacked like a skewer on the rotating coil spring. Eventually, the rotating coil spring cannot be inserted between the shield nozzle 52 and the contact tip 55, and the shield nozzle 52 and the contact There was a problem that the sputter 99 attached to the tip of the chip 55 could not be removed. In such a state, the operator has no choice but to remove the ring-shaped spatter 99 stacked in a coil spring on the coil spring. For example, in the case of an automated spot welding line, the ring-shaped spatter 99 is removed. For this purpose, the line itself has to be stopped, and there has been a problem that productivity is lowered. Alternatively, if the operator removes the ring-shaped spatter without stopping the line, there is a problem that the safety of the operator cannot be ensured.

The spring support member 4 has a substantially cylindrical shape. An attachment hole 4 a is formed in the center of the bottom surface of the spring support member 4. The inner diameter of the mounting hole 4 a is slightly larger than the outer diameter of the rotating shaft 1 a of the drive unit 1. On the side surface of the spring receiving member 4, a tightening screw hole 4b communicating with the mounting hole 4a is formed. The rotating shaft 1a is inserted into the mounting hole 4a, and in this state, the tightening screw 9 is tightened into the tightening screw hole 4b to attach the spring support member 4 to the rotating shaft 1a.
A spring support portion 4 c having an outer diameter substantially equal to the inner diameter of the coil spring 5 is formed at the upper end portion of the spring support member 4. A spring contact surface 4 d that is a plane orthogonal to the axial direction of the spring support member 4 is formed around the base end of the spring support portion 4. As shown in FIGS. 2 and 3, the spring support 4 is inserted into the coil spring 5, the lower end of the coil spring 5 is in contact with the spring contact surface 4d, and the coil spring 5 is attached to the spring support 4c. ing. At the center of the upper surface of the spring support member 4 (spring receiving portion 4c), a cylindrical rotary blade member support portion 4e protrudes.

The rotary blade member 2 is coaxially attached to the rotary blade member support portion 4e. The rotary blade member 2 is inserted through the coil spring 5. In other words, the coil spring 5 is disposed on the outer periphery of the rotary blade member 2 so as to be deformable. The rotary blade member 2 will be described in detail with reference to FIG. 4A is a top view of the rotary blade member 2, and FIG. 4B is a side view of the rotary blade member 2. The rotary blade member 2 has a cylindrical shape. The inner diameter of the rotary blade member 2 is substantially the same as the outer diameter of the rotary blade member support portion 4e. The rotary blade member support portion 4e is press-fitted into the rotary blade member 2, and the rotary blade member 2 is attached to the rotary blade member support portion 4e. At the upper end of the rotary blade member 2, a reduced diameter portion 2 a whose outer diameter gradually decreases toward the upper side is formed.
A slit blade 2b is formed on the side surface of the rotary blade member 2 from the upper end of the rotary blade member 2 to the middle portion thereof. The slit blade 2b is formed on the side surface of the rotary blade member 2 at a predetermined angle in the circumferential direction. In the embodiment shown in the figure, four slit blades 2b are formed on the side surface of the rotary blade member 2 with a circumferential direction of 90 °.

  As shown in FIG. 2 and FIG. 3, the tip deposit removal blade 3 is attached to the upper end of the coil spring 5 by welding. The tip deposit removal blade 3 will be described with reference to FIG. 5A is a top view of the tip deposit removal blade 3, FIG. 5B is a side view of the tip deposit removal blade 3, and FIG. 5C is a perspective view of the tip deposit removal blade 3. is there. The tip adhering matter removing blade 3 has a structure in which a plate-like blade 3b is attached to a substantially disc-shaped substrate 3a at a predetermined angle in the circumferential direction. A circular insertion hole 3c is formed in the center of the substrate 3a. The inner diameter of the insertion hole 3 c is slightly larger than the outer diameter of the rotary blade member 2. For this reason, the rotary blade member 2 can be inserted into the insertion hole 3e. The plate-like blades 3b are affixed radially on the substrate 3a. In other words, the plate-like blade 3b is stuck with the longitudinal direction thereof being the same as the radial direction of the substrate 3a. In the embodiment shown in the figure, four plate-like blades 3b are stuck on the substrate 3a with a circumferential direction of 90 °. As shown in FIG. 5A, the plate-like blade 3b protrudes up to the insertion hole 3c formed in the substrate 3a. An inclined surface 3d is formed on the surface protruding from the insertion hole 3c of the plate-like blade 3b, in other words, on the tip surface of the plate-like blade 3b. The inclined surface 3d gradually protrudes from the upper side to the lower side toward the center of the insertion hole 3c. In other words, the inclined surfaces 3d facing each other are widened upward. The inclination angle of the inclined surface 3d is the same as the inclination angle of the side surface of the tip portion of the contact chip 55, and the inclined surfaces 3d facing each other have a curved shape corresponding to the side surface of the tip portion of the contact chip 55. The width dimension of the plate-like blade 3 b is slightly smaller than the width dimension of the slit blade 2 b formed on the rotary blade member 2 of the rotary blade member 2. For this reason, the plate-like blade 3b can enter the slit blade 2b.

A welding surface 3f that is a flat surface is formed around the base end of the spring insertion portion 3e. With the spring insertion portion 3e inserted into the upper end of the coil spring 5 and the tip adhering matter removing blade 3 placed on the coil spring 5, the upper end of the coil spring 5 is welded to the welding surface 3f to remove the tip adhering matter. The blade 3 is attached to the upper end of the coil spring 5. With such a configuration, the rotary blade member 3 is held at the upper end of the rotary blade member 2 by the coil spring 5. In addition, each plate-like blade 3b of the tip adhering matter removing blade 3 coincides with a position where each slit blade 2b of the rotary blade member 2 is formed. For this reason, each plate-like blade 3 b can penetrate into each slit blade 2 b, and the tip adhering matter removing blade 3 can move downward with respect to the rotary blade member 2. As shown in FIGS. 2 and 3, the upper end of the rotary blade member 2 does not normally protrude upward from the plate-like blade 3b. When the plate-like blade 3b is pressed downward, each plate-like blade 3b enters each slit blade 2b, the rotary blade member 2 is inserted into the insertion hole 3c, and the tip deposit removal blade 3 moves downward. In the state where the tip adhering matter removing blade 3 is moved downward with respect to the rotary blade member 2, each plate-like blade 3b penetrates into each slit blade 2b and is engaged therewith. When the member 2 rotates, the tip deposit removal blade 3 also rotates.

  As shown in FIG. 2 and FIG. 3, a bottomed box-shaped spatter removal powder receiver 12 that is open upward is disposed at the top of the housing 11. The spatter removal powder receiver 12 surrounds the tip adhering material removal blade 3, the spring receiving member 4, the coil spring 5, and the rotary blade member 2.

  Above the spatter removal powder receiver 12, an inclined slope 13 surrounding the rotary blade member 2 and the upper part of the coil spring 5 and the tip adhering substance removal blade 3 is disposed. The inclined surface 13a that is the bottom surface of the inclined slope 13 is inclined with respect to the horizontal plane. In the embodiment shown in the figure, the inclined surface 13a is inclined so as to become lower toward the front of the arc welding torch cleaner 20 (the front side in FIG. 2). In the embodiment shown in the figure, a circular communication hole 13b is formed in the inclined surface 13a, and the rotary blade member 2 and the coil spring 5 are inserted into the communication hole 13b, so that the rotary blade member 2 and the coil spring 5 are inclined. Projecting upward from the surface 13a.

As shown in FIG. 2, an intrusion detection sensor 15 is disposed on the side slightly above the tip deposit removal blade 3. The intrusion detection sensor 15 detects the intrusion of the arc welding torch 50 directly above the tip deposit removal blade 3. In the present embodiment, the intrusion detection sensor 15 is a so-called photoelectric sensor, and includes a light emitting unit 15a that emits irradiation light such as laser light and a light receiving unit 15b that receives irradiation light emitted from the light emitting unit 15a. ing. The light emitting unit 15a and the light receiving unit 15b are arranged so that the straight line connecting the light emitting unit 15a and the light receiving unit 15b straddles the top adhering matter removing blade 3. When the arc welding torch 50 enters between the light emitting unit 15a and the light receiving unit 15b, the irradiation light irradiated from the light emitting unit 15a is blocked by the arc welding torch 50, and the light receiving unit 15b receives the irradiation light. Since this is not possible, the intrusion of the arc welding torch 50 is detected. The light receiving unit 15 a and the light emitting unit 15 b are connected to the control unit 10 disposed inside the housing 11. The actuator of the drive unit 1 is connected to the control unit 10. When the intrusion detection sensor 15 detects the intrusion of the arc welding torch 50 directly above the tip deposit removal blade 3, the actuator of the drive unit 1 is activated and the rotating shaft 1a rotates.
The intrusion detection sensor may be composed of an ultrasonic proximity sensor, a mechanical limit switch, or the like.

  A limit switch 16 is disposed on the upper side of the tip deposit removal blade 3. In this embodiment, the limit switch 16 is a roller lever type limit switch, and includes a limit switch body 15a having a valve therein, a lever 16b swingably attached to the limit switch body 16a, and a tip of the lever 16b. It is comprised from the roller 16c attached to rotation freely. The roller 16 c is located on the intrusion locus of the arc welding torch 50. When the roller 16c is pushed and the lever 16c is pushed from the initial position and swings (in the embodiment shown in FIG. 3, when the lever 16c swings toward the limit switch body 16a), the valve opens. On the other hand, when the lever 16b is in the initial position, the valve is closed. A compressed intake air supply pipe 19 to which compressed air such as factory compressed air is supplied is connected to the inlet side of the valve. A compressed air circulation pipe 17 is connected to the outlet side of the valve. A compressed air ejection pipe 18 is connected to the tip of the compressed air circulation pipe 17. The opening direction of the compressed air ejection pipe 18 is the upper surface direction of the tip deposit removal blade 3 from the upper side of the tip deposit removal blade 3 and the direction in which the inclined surface 13a is lowered. When the arc welding torch 50 enters directly above the tip deposit removal blade 3 and the roller 16c is pressed by the shield nozzle 50, the valve is opened and the tip is attached from the opening of the compressed air jet pipe 18. Compressed air is jetted onto the upper surface of the kimono removing blade 3. The effect of this will be described later.

(Operation of the present invention)
Next, the effect | action of this invention is demonstrated using FIG. In the example shown in FIG. 6A, a ring-shaped sputter 99 a is attached to the tip of the shield nozzle 52. The arc welding torch 50 is moved directly above the tip deposit removal blade 3 (state shown in FIG. 6A). Then, the intrusion detection sensor 15 detects the intrusion of the arc welding torch 50 directly above the tip adhering matter removing blade 3, and the actuator of the drive unit 1 is activated, so that the rotary blade member 2, the coil spring 5, and the tip attached The kimono removing blade 3 rotates. Further, the shield nozzle 52 presses the roller 16 c, and the compressed air is ejected from the compressed air ejection port 18 to the upper surface of the tip deposit removal blade 3.

  Next, when the arc welding torch 50 is further lowered, the tip deposit removal blade 3 is pressed by the tip of the shield nozzle 52 and lowered, and the tip of the rotary blade member 2 is inserted into the shield nozzle 52. Since the reduced diameter portion 2 a is formed at the upper end of the rotary blade member 2, the rotary blade member 2 can be easily inserted into the shield nozzle 52. Then, the spatter 99a adhering to the inside of the shield nozzle 52 is removed by the slit blade 2b formed on the rotary blade member 2, and the ring-shaped sputter 99a in contact with the plate-like blade 3b is removed from the shield nozzle 52. It peels off from the tip. Further, when the arc welding torch 50 is lowered and the tip of the contact tip 55 is inserted between the opposing plate-like blades 3b, the inclined surface 3d of the opposing plate-like blade 3b adheres to the tip of the contact tip 55. The sputter 99b is removed (FIG. 6B). At this time, the spatter removal powder is discharged from the lower part of the slit blade 2 b of the rotary blade member 2 to the spatter removal powder receiver 12.

Next, when the arc welding torch 50 is pulled upward, the tip deposit removal blade 3 is raised by the biasing force of the coil spring 5. When the coil spring 5 is fully extended, the ring-like spatter 99a peeled off from the tip of the shield nozzle 52 by the compressed air ejected from the compressed air jet tube 18 moves laterally on the tip deposit removal blade 3, and the inclined slope 13 And is discharged to the outside of the arc welding torch cleaner 20. (State in FIG. 6C).
Thus, in the present invention, the tip adhering matter removing blade 3 is attached to the upper end of the coil spring 5, and the upper end of the rotary blade member 2 is normally configured not to protrude upward from the plate-like blade 3b. Therefore, the ring-shaped spatter 99a peeled off from the tip of the shield nozzle 52 is not stacked on the rotary blade member 2 in a skewered manner. For this reason, even when the ring-shaped spatter 99a is generated at the tip of the shield nozzle 52, it becomes possible to continuously remove the spatters 99a and 99b attached to the tip of the shield nozzle 52 and the contact tip 55. .

  In the embodiment described above, when the limit switch 16 is disposed on the upper side of the tip deposit removal blade 3 and the arc welding torch 50 enters just above the tip deposit removal blade 3, the compressed air ejection pipe 18. Compressed air is jetted onto the top surface of the tip deposit removal blade 3 from above, but an electromagnetic valve that interlocks with the intrusion detection sensor 15 is provided, and the intrusion detection sensor 15 directly above the tip deposit removal blade 3 of the arc welding torch 50. It is possible to adopt a configuration in which intrusion into the gas is detected, the electromagnetic valve is opened, and compressed air is ejected from the compressed air ejection pipe 18 to the upper surface of the tip deposit removal blade 3.

  Although the present invention has been described above in connection with the most practical and preferred embodiments at the present time, the present invention is not limited to the embodiments disclosed herein. The arc welding torch cleaner with such changes is also included in the technical scope without departing from the spirit or concept of the invention that can be read from the claims and the entire specification.
