Description

[Detailed Description of the Invention] Technical Field The present invention relates to a so-called semi-automatic welding torch, in which an operator grips a holder and operates an operating switch to carry out appropriate welding.

Conventional technology Conventionally, this type of semi-automatic welding torch was
For example, the one shown in FIG. 1 is used.
That is, the operator grasps the holder to support the weight of the welding torch and cables, and operates the operation switch appropriately with his or her index finger to carry out semi-automatic welding work. By the way, in general, semi-automatic welding work involves various welding positions such as facing upward, facing downward, or standing upright, and welding work is performed in high places or in complicated places, which can cause severe fatigue in the fingers of the workers. It is hard work for the worker to repeatedly actuate the operating switch with the index finger while supporting the weight of the welding torch or the like with the fingers.

For this reason, the actual situation is that welding work time is kept short in consideration of worker fatigue.

Purpose of the invention The present invention has been made in view of the above problems, and aims to provide a semi-automatic welding torch that is easy to operate and places less burden on the operator.

Embodiments Hereinafter, the present invention will be described in detail with reference to illustrated embodiments.

In FIGS. 2 and 3, 1 is a holder, and various cables 2 and torch necks 3 are connected to the holder 1, for example. 4 is an operation switch installed in holder 1, 5 is holder 1
This support 5 is removably disposed on the support 5.
is a base portion 501, an intermediate portion 502, a tip portion 503,
504. The intermediate portion 502 of this support is formed into a substantially flat plate shape, and comes into contact with the bases of the worker's thumb and index finger when the worker grips the holder 1.
The tip portions 503 and 504 abut against the thumb side and the back side of the hand. In the illustrated case, the distal end 503 of the support,
504 is formed by bending a wire material, for example, and a buffer member made of vinyl, leather, cloth, etc. is provided on the outside. If the tip of the support is formed by bending the wire material in this way, the tip 5
Since the set shape of 03 and 504 can be made variable, the distal end of the support can be made to fit the wrist of each worker. Of course, in this case, it does not matter whether the worker's dominant hand is the right hand or the left hand. Note that the tips 503, 504 of the support
If formed by appropriately bending or notching a plate or strip of copper or copper alloy members, aluminum or aluminum alloy members, thin steel members, etc., the set shape can be made variable, so the same effect as above can be achieved. can be played. Despite this, the support 5 can be made of metal, synthetic resin, or the like. If the support 5 is created by molding in this manner, the manufacturing cost will be reduced. Of course, the support 5
Among them, the appropriate part that comes into contact with the worker's wrist,
By arranging the buffer member as described above, worker fatigue can be reduced.

In FIGS. 4 and 5, the tip portions 503 and 504 of the support 5 are formed of a flexible member such as leather or cloth. Therefore, the tip of the support comes into contact with the wrist of each worker. Of course, the base 501 and the tip 503 of the support
Attachment part with 504 or tip part of support tool 503,5
At the attachment part between 04 and holder 1, the tip portions 503, 5
04 can be configured to be freely adjustable.

In the above, welding is performed by the operator operating the operation switch while holding the welding torch while the supporter 5 is in contact with the wrist of the operator. That is, since the welding torch is supported by the wrist and fingers of the worker, the weight of the welding torch and various cables is distributed between the wrist and fingers.

In this way, since the welding torch is supported by the entire hand of the worker, the welding torch is easy to operate, and since the above-mentioned distributed force only acts on the worker's fingers, the welding torch is supported by the worker's entire hand. Fatigue is reduced and therefore long welding operations and repeated welding operations can be performed over long periods of time.

In the above explanation, if the support 5 is configured to come into contact with the thumb side and the back of the hand of the worker's wrist, the handling of the holder will be stabilized, but despite this, the support on the thumb side is omitted. can do. In addition, when the worker grips the holder, the welding torch is substantially supported by the contact between the middle part 502 of the support and the wrist, and the contact between the palm of the hand and the holder. If the abutting surface of the intermediate portion 502 of the supporting tool that comes in contact with the welding torch is made similar to the shape of the corresponding wrist of the worker who grips the holder, the operability of the welding torch will be further improved. Furthermore, I explained about the curved welding torch.
It can be applied to various types of welding torches such as straight-type and pistol-type welding torches. Of course, it can be applied to welding torches that use either consumable or non-consumable welding electrodes.

Effects of the invention In this invention, the holder is equipped with a support that comes into contact with the worker's wrist, making the welding torch easier to operate and reducing the burden on the worker. work and repeated welding work over a long period of time.
