JPS59232673A - Device for removing spatter from welding torch - Google Patents

Abstract

PURPOSE:To provide a titled device for removing spatters which removes automatically the spatters sticking to a welding torch during welding by inserting the tip of the welding torch to a spatter remover under rotation which coincides with the shape of the chip and nozzle of the welding torch attached to one end of a rotating body. CONSTITUTION:A rotational driving body 4 is rotated by tapping an actuator 14a and a spatter removing device 10 is rotated in the stage of approaching a welding torch to this device in order to remove spatters therefrom. The welding torch is at the same time descended to insert the tip thereof into the device 10 and the spatters sticking to the end A of the chip 1 and the end B of the nozzle 3 are removed by the end A' and step part B' of the device 10. The spatters sticking to the outside circumference of the chip 1 and sticking to the inside circumference of the nozzle 3 are removed by the inside and outside circumferences of the device 10. The removed spatters are dropped through the central parts 10a and 6a of the device 10 and the body 6 or dropped through the space between a bracket 9 and a sheath 12 and therefore there is no scattering of the spatters to the outside and all the spatters are dropped downward. If a receiving tray is provided underneath this device, the spatters are completely recovered.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a welding torch that automatically removes spatter that accumulates on the wire feeding tip and encapsulated gas nozzle of the welding torch during welding. This invention relates to a spatter removal device.

Conventional configuration and its problems In arc welding machines that use consumable electrode wires, spatter usually occurs, and this welding
It sticks to some parts.

In particular, the wire that attaches to the chi knob for wire feeding will completely impede the wire feeding, and the vines that adhere to the nozzle of the encapsulated gas and ITI will act as a shield for the encapsulated gas.
Inhibits fi intentions. In addition, spatter that has settled on the chips and nozzles often falls during welding and adversely affects the welded area.

Therefore, in automatic welding work where cleaning by hand W+ is not performed during welding work, what is the problem with automatic welding work? Dealing with ivy has become a big problem.

Conventionally, the first solution to this problem has been to have workers regularly clean the ivy, but this can be difficult due to the line configuration, especially in automatic welding operations. many. For this reason, during automatic welding work, a wire brush 11'X was used, and the nozzle and tip of the welding torch were brought into contact with it at appropriate times to remove spatter.

However, in this case, the removed Sunokunotaka;
: 'i'1, and it is rarely put to practical use because it may invade the mechanical mechanism and have an adverse effect, or it may accumulate on cleaning tools such as wire brushes, impairing the cleaning function. Another disadvantage was that the nozzle and tip of the welding torch were easily damaged.

OBJECTS OF THE INVENTION The present invention eliminates all of the above-mentioned drawbacks of the conventional technology, and eliminates the problem of spatter being scattered outside the machine without damaging the wire feeding tip or encapsulated gas nozzle of the welding torch. The object of the present invention is to provide a spatter removal device for welding that does not adversely affect mechanical parts. .

Structure of the Invention In order to achieve all of these objects, the present invention provides a rotating part συ which rotates based on an external signal, which is connected to a rotating body via a rotating conductor, and welded to one end of the rotating body. -- Attach all the spatter removal tools that match the shape of the tip and nozzle of 1, and form the rotation center of the rotating body and the spatter removal tool entirely hollow, and remove the spatter from the rotating body, the rotating body, and the spatter removal tool. An outer cover is provided that covers at least the side surfaces of the tool, separating the main body of the tool and the space between the parts. .

Description of examples An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a tip for feeding wires 1 to 1 for welding, and a wire 2 is continuously fed from this tip 1.

3 is a nozzle for encapsulated gas.
It easily adheres to the end A of the tip 1 and the end B of the nozzle 3, and also to the outer periphery of the 1000-knob 1 and the inner periphery of the nozzle 3, but it rarely adheres to the outer periphery of the nozzle 3.

Reference numeral 4 denotes a rotary driving body such as an electric motor, and a gear 5 is attached to the shaft of the rotating body 4. 6 is the above tA
! The rotating body 6 is rotated 11 by + 15, and the central part 6 of the rotating body 6 is hollow. Reference numbers 1, 8, and 8 are bearings, and the rotating body 6 is connected to the bracket 9 through the bearings 7 and 8. I support it. 10 is a spatter remover,
The core portion 10a is hollow and is attached to the rotating body 6 by means of a TV screw 11.

Reference numeral 12 denotes an outer cover that covers at least the side surfaces of the rotary drive body 4, the rotary main body 6, the spatter remover 10, etc. with a gap therebetween, and the outer cover 12 is partially connected to the bracket 9 by the stay 13. combined. 14 is a signal switch, which is turned on and off by its actuator 14 &
F.

Next, the operation of this embodiment will be explained.

When the welding torch 1-- approaches this device to undergo spatter removal, the actuator 14&ff rotates the rotary drive body 4 and rotates the spatter removal tool 1Q (i-). At the same time, the welding torch The spatter is lowered from the state of The spatter removed by the attachment part B' and attached to the outer periphery of the nap 1 and the inner periphery of the nozzle 3 is removed by the inner and outer periphery of the spatter removal tool 10.The material of the spatter removal tool 10 is In order to avoid damaging the spatter removal tool 10, it is preferable to use heat-resistant fibers.
The outer diameter of the knob 1 can be made smaller than the outer diameter of the knob 1 to make it easier to remove the ivy from the end A of the knob 1. The removed snow ivy either falls through the center part 101... and 6&f of the main body 6 of the S/RI-I-NOTA remover 10, or falls as much as 120 kmJ between the Plaque no 1-9 and the outer cover 120. Since all the particles fall downward without scattering to the outside, all of the particles can be rotated if a tray (not shown) is provided in a part of the device-1.

The operation of this device is such that the rotary drive body 4 is operated for a certain period of time after the signal switch 14 detects the signal. ,'l 'l'z
t or by changing the shape of the actuator 14a, and during the spatter removal operation, the drive body 4 moves +11 times only during the period when the actuator 142L is in contact with the nozzle 3.
Either configuration is acceptable.

Effects of the Invention According to the present invention, with a simple configuration, it is possible to reliably remove the splinters attached to the tip of the 1-chi during welding.
The removed snow ivy will not scatter to other places and its function can be maintained for a long time, and when welding using a welding robot, the robot should be taught how to approach, insert, and remove the torch from this device. If this is done, the sputter removal operation can be easily performed, which is an excellent effect.
