Embodiment 1

[0030] Such as Figure 1-3 , a hand-held welding torch, including a gun body containing a handle and a gun barrel 2, and a positioning unit 3 connected to the gun body; the front and rear positioning slots 201 and Rear positioning draw-in groove 202, form between described front positioning draw-in groove 201 and described rear positioning draw-in groove 202, the strip-shaped clamping space that can accommodate strip-shaped steel material 4, strip-shaped steel material 4 can pass through; The unit 3 has a positioning surface 301 perpendicular to the long axis direction of the strip-shaped clamping space. In the working state, the positioning surface 301 is attached to the reference surface to be welded to complete the positioning of the handheld welding torch.

[0031]As mentioned above, the present invention provides a hand-held welding torch, the torch body of which includes a handle and barrel 2 . The gun barrel 2 and the gun handle are cross-connected at right angles or a...

Embodiment 2

[0033] The present embodiment is further limited on the basis of embodiment 1:

[0034] The positioning unit 3 is provided with a flux 302, the flux 302 is located on the positioning surface 301, and the flux 302 is located on the long axis straight line of the strip-shaped clamping space; The contact electrode 204 to be contacted by the welding object is provided with a welding switch 101 in signal connection with the contact electrode 204 on the handle of the gun. In this technical feature, since the flux 302 is located on the positioning surface 301, when the positioning welding operation is performed, the positioning surface 301 and the reference plane to be welded are attached to each other, so the flux 302 located on the positioning surface 301 is also in contact with the reference surface to be welded. The reference surface of the strip is closely attached, and the flux 302 is located on the long axis straight line of the strip-shaped clamping space, and the strip-shape...

Embodiment 3

[0043] Such as Figure 4-8 , a method of operation of a hand-held welding torch:

[0044] S1 puts the strip steel material 4 from the top of the gun body, and aligns the front end of the strip steel material 4 with the front end of the gun body.

[0045] S2 Press the locking switch 102 , the strip-shaped steel material 4 is locked by the mechanical gripper 203 and contacts the contact electrode 204 , and the strip-shaped steel material 4 is automatically moved to a specified length protruding from the gun barrel 2 .

[0046] S3 Utilize the first permanent magnet 206 to absorb the second permanent magnet 304 on the positioning ring, temporarily fix the positioning ring to the front end of the gun body.

[0047] S4 Align the 4 ends of the strip steel with the designated welding position, press the welding switch 101 after pushing it tightly, start the welding torch, turn on the power and start welding.

[0048] After S5 welding is completed, press the locking switch 102 again,...

Abstract

The invention discloses a handheld welding gun, and relates to the technical field of welding equipment. The handheld welding gun comprises a gun body comprising a gun handle and a gun barrel, and further comprises a positioning unit connected with the gun body. A front positioning clamping groove and a rear positioning clamping groove are formed in the front end and the rear end of the outer portion of the gun barrel respectively, and a strip-shaped clamping space capable of containing strip-shaped steel and allowing the strip-shaped steel to penetrate through is formed between the front positioning clamping groove and the rear positioning clamping groove. The positioning unit is provided with a positioning face perpendicular to the long axis direction of the strip-shaped clamping space. In the working state, the positioning face is attached to a datum plane to be welded to complete positioning of the handheld welding gun. The handheld welding gun is provided with the open and through front positioning clamping groove, the strip-shaped clamping space and the rear positioning clamping groove which are located outside the gun barrel and sequentially connected, the welding gun can rapidly clamp strip-shaped steel of different sizes through cooperation of the front positioning clamping groove, the strip-shaped clamping space and the rear positioning clamping groove, and T-shaped welding of a steel plate and the strip-shaped steel is achieved through cooperation of the arranged positioning unit.

Description

technical field [0001] The present invention relates to the technical field of welding equipment, and further relates to the technical field of civil construction welding equipment, in particular to a hand-held welding torch. Background technique [0002] Civil and construction projects often need to weld steel bars and steel plates. The welding of steel bars and steel plates is mainly divided into three types of welding. After the steel plate is punched or cut, the steel bar is inserted into the hole, which is divided into half-insert type, full-insert type and through-type, and then welded; the third is that the transverse axis of the steel bar is in contact with the steel plate, and the steel bar The surface where the diameter is located is in contact with the steel plate and welded by fillet weld circumference welding. [0003] Among them, in the prior art, the third type adopts fillet weld peripheral welding to weld steel bars and steel plates, that is, T-shaped weldin...
