Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to an argon arc welding device. Background Art

[0002] Argon arc welding is a welding technology that uses argon as a shielding gas, also known as argon gas shielded welding. It is to pass argon shielding gas around the arc welding to isolate the air outside the welding area to prevent oxidation of the welding area.

[0003] However, in the prior art, when using an argon arc welding gun for welding operations, it is sometimes necessary to use it together with a welding wire. The welding wire needs to be fed evenly when in use, but the feeding of the welding wire is generally controlled manually. However, under manual control, it is impossible to stably ensure the uniform feeding of the welding wire, which in turn affects the welding effect. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art: the feeding of welding wire is generally controlled manually, but the uniform feeding of welding wire cannot be stably guaranteed under the manual control, which further affects the welding effect.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an argon arc welding device, including an argon arc welding gun, one side of the argon arc welding gun is fixedly connected to a mounting piece, and one side of the mounting piece is clamped and connected to a clamping block, one end of the clamping block is fixedly connected to an electric telescopic rod, one end of the electric telescopic rod is fixedly connected to a connecting plate, and one end of the connecting plate is inserted and connected with a welding wire, the connecting plate is slidably connected to a rubber pressure plate near a welding wire insertion port, and a screw rod is rotatably connected to a surface of one side of the rubber pressure plate, and the screw rod and the connecting plate are threadedly connected.

[0006] As a preferred embodiment, a bolt is threadedly connected on the surface of the mounting piece, and a fastener is threadedly connected on the surface of the bolt.

[0007] As a preferred embodiment, a slider is fixedly connected to one side of the fastener, and the slider is slidably connected to the mounting member.

[0008] As a preferred implementation, one end of the screw rod is fixedly connected to a torsion disk.

[0009] As a preferred embodiment, an anti-slip strip is fixedly connected to the outer surface of the torsion disk, and a plurality of anti-slip strips are equidistantly arranged around the center of the torsion disk.

[0010] Compared with the prior art, the advantages and positive effects of the utility model are:

[0011] The utility model allows the welding wire to pass through the front end of the connecting plate so that one end of the welding wire is close to the welding port of the argon arc welding gun, and the rubber pressing plate is driven forward by the rotating screw rod to quickly squeeze and fix the welding wire on the connecting plate. Later, during the welding process of the argon arc welding gun, the electric telescopic rod is controlled to shrink at a uniform speed through an external remote control, so that the connecting plate drives the welding wire to be fed at a uniform speed, thereby ensuring the welding quality.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example 1

[0019] like Figure 1-3As shown, the utility model provides a technical solution: an argon arc welding device, including an argon arc welding gun 1, one side of the argon arc welding gun 1 is fixedly connected with a mounting member 2, and one side of the mounting member 2 is clamped and connected with a clamping block 6, with the help of the clamping block 6, the electric telescopic rod 5 can be quickly installed on one side of the argon arc welding gun 1 for use, one end of the clamping block 6 is fixedly connected with the electric telescopic rod 5, and one end of the electric telescopic rod 5 is fixedly connected with a connecting plate 7. During the welding process of the argon arc welding gun 1, the electric telescopic rod 5 is uniformly contracted by an external remote control, so that the connecting plate 7 can be connected. The connecting plate 7 drives the welding wire 8 to feed at a uniform speed to ensure the welding quality, and one end of the connecting plate 7 is inserted with the welding wire 8, and the connecting plate 7 is slidably connected with a rubber pressure plate 9 near the insertion port of the welding wire 8, and a screw rod 10 is rotatably connected to the surface of one side of the rubber pressure plate 9, and the screw rod 10 is threadedly connected to the connecting plate 7, and the welding wire 8 is passed through the front end of the connecting plate 7 so that one end of the welding wire 8 is close to the welding port of the argon arc welding gun 1, and the rubber pressure plate 9 is driven to move forward by rotating the screw rod 10 to quickly extrude and fix the welding wire 8 on the connecting plate 7.

[0020] Example 2

[0021] like Figure 1-3 As shown, a bolt 3 is threadedly connected to the surface of the mounting member 2, and a fastener 4 is threadedly connected to the surface of the bolt 3. The fastener 4 is installed on the mounting member 2 by the bolt 3 to squeeze the electric telescopic rod 5, thereby further improving the stability of the electric telescopic rod 5 installed on the argon arc welding gun 1. A slider is fixedly connected to one side of the fastener 4, and the slider is slidably connected to the mounting member 2. With the help of the slider, the fastener 4 is allowed to move within a fixed range on the mounting member 2, which facilitates the docking of the fastener 4 with the threaded hole on the mounting member 2 and the subsequent installation of the bolt 3. A torsion disk 11 is fixedly connected to one end of the screw rod 10. The setting of the torsion disk 11 facilitates the manual control of the rotation of the screw rod 10. An anti-slip strip is fixedly connected to the outer surface of the torsion disk 11, and a number of anti-slip strips are equidistantly arranged around the center of the torsion disk 11. The setting of the anti-slip strip plays an anti-slip role when the torsion disk 11 is manually rotated.

[0022] Working principle:

[0023] like Figure 1-3 As shown, when the utility model is in use, the user first manually passes the welding wire 8 through the front end of the connecting plate 7. When one end of the welding wire 8 is close to the welding port of the argon arc welding gun 1, the user uses the other hand to rotate the torsion disk 11 to drive the screw rod 10 to rotate and move, thereby causing the rubber pressing plate 9 to move and squeeze the welding wire 8, so that the welding wire 8 can be quickly fixed on the connecting plate 7. Then, the switch of the argon arc welding gun 1 is turned on to align the welding port for welding. At this time, the electric telescopic rod 5 is controlled by an external remote control to shrink at a uniform speed, driving the connecting plate 7 to move downward at a uniform speed, thereby achieving the effect of uniform feeding of the welding wire 8, thereby ensuring the welding quality.
