[0002] Oxygen welding machine is the abbreviation of carbon dioxide gas shielded welding machine, which uses carbon dioxide as the welding shielding gas and often uses highly deoxidized welding wire. It is one of the important welding tools for welding ferrous metals. Oxygen welding machine is manufactured using advanced technology, with reliable performance and strong overload capacity. It is suitable for gas shielded welding of various low carbon steels and low alloy steels. It is characterized by high efficiency, which can make production efficiency several times higher than manual arc welding, with significant power saving and low production cost. It can be specially used for welding thin plates and medium and thick plates, with small welding heat affected zone, small deformation and beautiful weld formation.

DETAILED DESCRIPTION

[0024] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0025] The utility model provides a gas supply device for a dioxygen welding machine, comprising a gas supply bottle 2, and further comprising:

[0026] A protective box 1, wherein the gas supply cylinder 2 is arranged in the protective box 1;

[0027] The protective box 1 is used to carry and protect the gas supply cylinder 2, preventing external objects from hitting the gas supply cylinder 2, causing damage to the gas supply cylinder 2, and preventing the damaged gas supply cylinder 2 from causing harm to the personal safety of the staff. At the same time, the upper end of the protective box 1 is threadedly connected with a sealing cover, which can seal the protective box 1.

[0028] The carrier frame 3 is arranged on the inner lower end surface of the protection box 1;

[0029] The carrier 3 is fixedly mounted on the inner lower end surface of the protection box 1 and can remain fixed;

[0030] The rubber block 4 is provided on the upper end surface of the carrier 3;

[0031] The lower end surface of the rubber block 4 is bonded to the upper end surface of the carrier 3, which makes it easy for staff to replace the rubber block 4 when it is damaged.

[0032] A placement groove 5 is formed with the upper end surface of the rubber block 4, and the lower end of the gas supply bottle 2 is arranged in the placement groove 5;

[0033] Sliders 6, a pair of which are slidably mounted on the inner lower end surface of the protective box 1;

[0034] The connecting frame 7 is fixedly mounted on the upper end surface of the slider 6;

[0035] The arc-shaped clamping block 8 is fixedly mounted on the end of the connecting frame 7 away from the slider 6, and its inner surface contacts the outer wall of the gas supply bottle 2;

[0036] The bidirectional threaded rod 9 is rotatably mounted in the protective box 1 and is threadedly connected to a pair of sliders 6 respectively;

[0037] A motor is fixedly installed on the outer wall of the protective box 1. The output end of the motor is fixedly connected to one end of the bidirectional threaded rod 9, which can drive it to rotate. When the bidirectional threaded rod 9 rotates, it can drive a pair of sliders 6 and a pair of connecting frames 7 to move, so that a pair of arc-shaped clamping blocks 8 clamp the gas supply bottle 2 to keep it stable in the protective box 1.

[0038] Specifically, a pair of limiting grooves 10 are formed on the inner lower end surface of the protection box 1, and a limiting block 11 is fixedly mounted on the lower end surface of the slider 6 and is slidably connected to the limiting grooves 10;

[0039] Under the action of the limiting groove 10 and the limiting block 11 , the slider 6 can be made more stable when sliding.

[0040] Specifically, a pair of limiting rods 12 are fixedly mounted on the inner wall of the protection box 1, and the limiting rods 12 slide through the connecting frame 7 at one end away from the protection box 1;

[0041] Under the action of the limiting rod 12, the connecting frame 7 can be kept stable when sliding to prevent it from shaking.

[0042] Specifically, an air outlet pipe 13 is fixedly passed through one side wall of the protective box 1, and one end of the air outlet pipe 13 located inside the protective box 1 is fixedly connected to a hose 14, and the end of the hose 14 away from the air outlet pipe 13 is connected to the air outlet end of the gas supply bottle 2;

[0043] One end of the hose 14 is fixedly mounted with an annular connector, which is threadedly connected to the outlet end of the gas supply bottle 2, so that the gas in the gas supply bottle 2 can flow through the hose 14 to the outlet pipe 13;

[0044] A valve 15 is fixedly installed on one end of the air outlet pipe 13 located outside the protective box 1;

[0045] The valve 15 can close or open the gas outlet pipe 13 , preventing gas from flowing out when closed and facilitating gas outflow when opened.

[0046] Specifically, a rubber pad 16 is provided on the inner surface of the arc-shaped clamping block 8;

[0047] The rubber pad 16 is bonded to the inner surface of the arc-shaped clamping block 8, which is convenient for the staff to replace. At the same time, when a pair of arc-shaped clamping blocks 8 clamp the gas supply bottle 2, it can increase the friction force and prevent the arc-shaped clamping block 8 from damaging the surface of the gas supply bottle 2.

[0048] Specifically, the lower end surface of the protective box 1 is provided with moving wheels 17 for transportation;

[0049] There are two pairs of moving wheels 17 , both of which are rotatably mounted on the lower end surface of the protection box 1 , which can facilitate the staff to transport the protection box 1 .

[0050] Working principle: First, the staff opens the sealing cover and places the lower end of the gas supply bottle 2 into the placement groove 5. At this time, the staff rotates the annular connector and connects one end of the hose 14 to the gas outlet end of the gas supply bottle 2, so that the gas outlet end of the gas supply bottle 2 is connected to the hose 14. At this time, the staff starts the motor, and the rotation of the motor output end can drive the two-way threaded rod 9 to rotate. When the two-way threaded rod 9 rotates, it can drive a pair of sliders 6 and a pair of connecting frames 7 to move, so that a pair of arc-shaped clamps 8 clamp the gas supply bottle 2 to keep it stable in the protective box 1. At this time, the staff turns off the motor and opens the gas supply bottle 2 at the same time, so that the gas inside it can enter the hose 14 from the gas outlet end, and at the same time thread the sealing cover to the protective box 1 to seal the protective box 1. At this time, the staff connects the external welding machine equipment with the outlet pipe, opens the valve 15, and allows the gas in the hose 14 to enter the external welding machine through the outlet pipe 13, bringing convenience to people.
