Description

Technical Field

[0001] The present invention relates to the technical field of welding, and in particular to a metal material welding mechanism. Background Art

[0002] Arc welding, also known as argon gas shielded welding, is a welding technique that uses argon as a shielding gas. Based on the principles of conventional arc welding, it utilizes argon gas to protect the metal welding material. High current is used to melt the welding material into a liquid state on the base material being welded, forming a molten pool. This achieves a metallurgical bond between the metal being welded and the welding material. Argon shielding gas is passed around the arc welding process, isolating air from the weld zone to prevent oxidation. Types of argon arc welding include pulsed argon arc welding and manual tungsten inert gas welding. Because argon is continuously supplied during high-temperature molten welding, argon arc welding prevents the welding material from coming into contact with oxygen in the air, thereby preventing oxidation. Therefore, it is suitable for welding stainless steel and iron hardware.

[0003] When welding metal materials, argon arc welding is usually used. However, when using some existing argon arc welding machines, the tank containing argon gas is usually directly connected to the argon arc welding machine. However, with long-term use, the argon gas inside the tank becomes less and less. When welding, the argon gas content inside the tank decreases, and the ejected argon gas becomes less and less. As a result, the argon gas content at the welding point is insufficient, and the welding point lacks argon gas protection, which affects the welding point and the welding effect.

[0004] In view of the above problems, a metal material welding mechanism is proposed. Summary of the Invention

The argon gas delivery pipe 4 passes through the ventilation block 3 and the storage box 2 and extends to one side of the storage box 2. The argon gas delivery pipe 4 is connected to the argon arc welding machine 1. Rubber sealing pads are fixedly installed on the inside of the two docking nozzles 5. Four support and limiting rods 34 are fixedly installed on one side of the ventilation block 3. Two movable bases 7 are slidably connected to the four support and limiting rods 34. Tension springs 33 are fixedly installed on the two movable bases 7. The other ends of the two tension springs 33 are fixedly connected to the interior of the storage box 2. Gas cylinders 6 are provided inside the two movable bases 7, and the output ends of the two gas cylinders 6 are respectively docked with the two docking nozzles 5.

[0022] The two movable bases 7 are provided to facilitate the support and movement of the gas cylinder 6, and at the same time restrict the gas cylinder 6 to prevent the gas cylinder 6 from being separated from the docking nozzle 5, thereby preventing gas leakage.

[0023] The provision of the rubber sealing pad facilitates sealing of the joint between the gas cylinder 6 and the docking nozzle 5, thereby preventing leakage and improving the sealing performance of the device.

[0024] An ejector pin 35 is fixedly installed inside the two docking nozzles 5 .

[0025] The two ejector pins 35 are provided so that when the gas cylinder 6 is docked with the docking nozzle 5 , the ejector pins 35 can squeeze the sealing valve on the gas cylinder 6 , thereby discharging the argon gas inside the gas cylinder 6 .

[0026] The ventilation block 3 is internally slidably connected with four push rods 8, and the four push rods 8 are respectively inserted into the second cavity 17 and the third cavity 18 in a group of two. A connecting plate 19 is fixedly installed on the two groups of push rods 8, and a push plate 9 is fixedly installed on the four push rods 8. The four push plates 9 are provided with a dumping drive groove 10, and the dumping drive groove 10 is inclined. Four fixed seats 14 are fixedly installed inside the storage box 2, and the interiors of the four fixed seats 14 are slidably connected with insertion rods 13. One end of the four insertion rods 13 is inclined, and the other ends of the four insertion rods 13 are fixedly installed with first elastic springs 15, which are respectively fixedly connected to the four insertion rods 13. Sliding push rods 11 are fixedly installed on the four insertion rods 13, and the four sliding push rods 11 are respectively slidably connected to the interiors of the four dumping drive grooves 10. Two movable bases 7 are provided with two sockets 12, and the four insertion rods 13 are respectively engaged with the interiors of the four sockets 12.

[0027] When the movable base 7 is moved to the outside of the storage box 2, the gas cylinder 6 is placed inside the movable base 7, and then the movable base 7 is pushed to move, so that the movable base 7 slides on the two support limit rods 34 and the tension spring 33 is stretched. When the two insertion rods 13 come into contact with the movable base 7, the movable base 7 will squeeze the inclined surfaces of the two insertion rods 13, and then the two insertion rods 13 will move back to back, so that the two insertion rods 13 slide inside the two fixed seats 14 and squeeze the two first elastic springs 15, and at the same time, the two sliding push rods 11 will squeeze the two dumping drive rods 11. The inner wall of the movable groove 10 is squeezed, thereby moving the two push plates 9. When the two insertion rods 13 coincide with the two insertion holes 12, the two insertion rods 13 are reset by the elastic force of the two first elastic springs 15, thereby inserting the two insertion rods 13 into the inside of the two insertion holes 12, completing the fixation of the movable base 7, and docking the gas cylinder 6 with the docking nozzle 5. The two movable bases 7 are fixed in the same way, which is convenient for fixing the gas cylinder 6 and the movable base 7, thereby improving the safety of the gas cylinder 6 during use and preventing leakage.

[0028] The connecting pipe 29 is internally connected to a valve stem 37 for rotation. A valve ball 36 is fixedly installed at one end of the valve stem 37 located inside the connecting pipe 29. The valve ball 36 rotates inside the connecting pipe 29. A push handle 30 is fixedly installed at the upper end of the valve stem 37. A torsion spring 38 is movably sleeved on the surface of the valve stem 37. The upper end of the torsion spring 38 is fixedly connected to the push handle 30, and the lower end of the torsion spring 38 is fixedly connected to the connecting pipe 29.

[0029] The exhaust valves on the two gas cylinder bottles 6 are opened by squeezing the two ejector pins 35, so that the argon gas inside the two gas cylinder bottles 6 enters the second cavity 17 and the third cavity 18 through the two docking nozzles 5. Since the second cavity 17 and the third cavity 18 are connected through the connecting pipe 29, and the connecting pipe 29 is sealed by the valve ball 36, the argon gas inside the second cavity 17 cannot enter the third cavity 18. The argon gas inside the third cavity 18 enters the first cavity 16 through the connecting hole 22, and then enters the argon gas delivery pipe 4. Since the argon gas delivery pipe 4 is connected to the argon gas pipe on the argon arc welding machine 1, the argon gas enters the interior of the argon arc welding machine 1, thereby realizing the argon gas delivery to the argon arc welding machine 1.

[0030] Two support rods 26 are fixedly installed inside the second cavity 17 and the third cavity 18, and two movable sealing plates 20 are slidably connected to the four support rods 26. Rubber sealing plugs 21 are fixedly installed on the two movable sealing plates 20, and the two rubber sealing plugs 21 are respectively docked with the two docking nozzles 5. Reset springs 27 are movably sleeved on the four support rods 26, and the four reset springs 27 are respectively fixedly connected to the inside of the third cavity 18 and the second cavity 17, and the four reset springs 27 are respectively fixedly connected to the two movable sealing plates 20 at one end close to the two movable sealing plates 20.

[0031] In the initial state, the two rubber sealing plugs 21 are inserted into the interior of the two docking nozzles 5. When the argon gas inside the gas cylinder 6 reaches the interior of the docking nozzle 5, the discharged argon gas will push the rubber sealing plug 21 and the movable sealing plate 20 to move, so that the movable sealing plate 20 slides on the two support rods 26, and then squeezes the two return springs 27. The two movable sealing plates 20 are moved in the above manner. When the argon gas inside the gas cylinder 6 connected to the third cavity 18 is insufficient, the movable sealing plate 20 and the rubber sealing plug 21 will be reset by the elastic force of the two return springs 27, so that the rubber sealing plug 21 is pressed against the third cavity 18. The docking mouth 5 on the three cavities 18 is sealed, and when the movable sealing plate 20 moves, the movable sealing plate 20 squeezes the connecting plate 19 inside the third cavity 18, thereby moving the two push rods 8 and the two push plates 9, and then the two sliding push rods 11 slide along the inclined surfaces of the two tilting drive grooves 10, so that the two insertion rods 13 move away from each other, and squeeze the two first elastic springs 15, thereby disengaging the two insertion rods 13 from the two insertion holes 12, and then the movable base 7 is reset by the tension of the tension spring 33, and then the movable base 7 is moved to the outside of the storage box 2.

[0032] When the argon gas inside the gas cylinder 6 connected to the interior of the second cavity 17 is insufficient, the rubber sealing plug 21 inside the second cavity 17 is used to seal the nozzle 5 in the same way, and the gas cylinder 6 is discharged, so as to remind the staff that the argon gas inside the gas cylinder 6 is consumed, and then remind the staff to replace the gas cylinder 6 in time, thereby improving the convenience of replacing the gas cylinder 6 and avoiding poor metal welding results due to failure to replace the gas cylinder 6 in time.

[0033] When the movable sealing plate 20 inside the third cavity 18 is reset, the movable sealing plate 20 will squeeze the pushing handle 30, and the pushing handle 30 will drive the valve stem 37 to rotate, thereby causing the torsion spring 38 to deform, and at the same time, the valve stem 37 will drive the valve ball 36 to rotate, thereby opening the connecting pipe 29, and allowing the argon gas inside the second cavity 17 to enter the interior of the third cavity 18 through the connecting pipe 29, and then enter the interior of the first cavity 16 and the argon delivery pipe 4, thereby delivering argon gas, avoiding poor welding effect due to insufficient argon gas, facilitating the alternating replacement or use of the gas cylinder 6, always keeping sufficient argon gas, and improving the welding effect on metal materials.

[0034] The ventilation block 3 is slidably connected to a square rod 24 inside, one end of the square rod 24 is located inside the second cavity 17, and the other end of the square rod 24 is located inside the third cavity 18. A blocking rod 23 is fixedly installed on the end of the square rod 24 located inside the third cavity 18, and a second elastic spring 25 is movably sleeved on the square rod 24. The end of the second elastic spring 25 close to the blocking rod 23 is fixedly connected to the blocking rod 23, and the end of the second elastic spring 25 away from the blocking rod 23 is fixedly connected to the inner wall of the third cavity 18. An extrusion protrusion 28 is fixedly installed on the movable sealing plate 20 inside the third cavity 18, an inclined guide plate 32 is fixedly installed on the movable sealing plate 20 inside the second cavity 17, and an extrusion protrusion 31 is fixedly installed on the square rod 24.

[0035] When the extrusion protrusion 28 follows the movable sealing plate 20 to return to its original position, the extrusion protrusion 28 will squeeze the inclined surface of the blocking rod 23, thereby causing the blocking rod 23 and the square rod 24 to move and squeeze the second elastic spring 25. When the extrusion protrusion 28 contacts the other inclined surface of the blocking rod 23, the blocking rod 23 will be reset by the elastic force of the second elastic spring 25, thereby causing the blocking rod 23 to squeeze the extrusion protrusion 28, thereby fixing the movable sealing plate 20. When the newly replaced gas cylinder bottle 6 is injected into the docking nozzle 5, the rubber sealing plug 21 and the movable sealing plate 20 are blocked by the blocking rod 23 and cannot be reset, thereby preventing the argon gas inside the gas cylinder bottle 6 from entering the interior of the third cavity 18. When there is no argon gas in the gas cylinder bottle 6 connected to the second cavity 17, the movable sealing plate 20 inside the second cavity 17 will be reset, causing the inclined guide plate 32 to contact the extrusion protrusion 31, thereby causing the extrusion protrusion 31 to move along the inclined surface of the inclined guide plate 32. When the cam 32 is in the closed position, the second stop 32 is pressed against the stop 23, and the stop 23 is pressed against the stop 23. When the cam 32 is in the closed position, the stop 23 is pressed against the stop 23, and the stop 23 is pressed against the stop 23. The cam 32 is pressed against the stop 23, and the stop 23 is pressed against the stop 23.

[0036] During the initial installation, first push the movable sealing plate 20 inside the second cavity 17 through the external tamping rod, and then install the gas cylinder 6 on the third cavity 18. Then, stop tamping the movable sealing plate 20 on the second cavity 17, reset the movable sealing plate 20, open the movable sealing plate 20, and then install the gas cylinder 6 on the second cavity 17 to complete the preliminary installation.

[0037] Working principle: When the two levers 13 are in contact with the movable base 7, the movable base 7 is pressed against the inclined surfaces of the two levers 13, thereby causing the two levers 13 to move back to back, causing the two levers 13 to slide inside the two fixed seats 14 and press the two first elastic springs 15. At the same time, the two sliding push rods 11 are pressed against the inner walls of the two tilting drive grooves 10, thereby causing the two push plates 9 to move. When the two levers 13 coincide with the two insertion holes 12, the two levers 13 are reset by the elastic force of the two first elastic springs 15, thereby causing the two levers 13 to be inserted into the inside of the two insertion holes 12, completing the fixation of the movable base 7, causing the gas cylinder 6 to dock with the docking nozzle 5, and the two movable bases 7 are fixed in the same way, which is convenient for fixing the gas cylinder 6 and the movable base 7.

[0038] The exhaust valves on the two gas cylinder bottles 6 are opened by squeezing the two ejector pins 35, so that the argon gas inside the two gas cylinder bottles 6 enters the second cavity 17 and the third cavity 18 through the two docking nozzles 5. Since the second cavity 17 and the third cavity 18 are connected through the connecting pipe 29, and the connecting pipe 29 is sealed by the valve ball 36, the argon gas inside the second cavity 17 cannot enter the third cavity 18. The argon gas inside the third cavity 18 enters the first cavity 16 through the connecting hole 22, and then enters the argon gas delivery pipe 4. Since the argon gas delivery pipe 4 is connected to the argon gas pipe on the argon arc welding machine 1, the argon gas enters the interior of the argon arc welding machine 1, thereby realizing the argon gas delivery to the argon arc welding machine 1.

[0039] In the initial state, the two rubber sealing plugs 21 are inserted into the interior of the two docking nozzles 5. When the argon gas inside the gas cylinder 6 reaches the interior of the docking nozzle 5, the discharged argon gas will push the rubber sealing plug 21 and the movable sealing plate 20 to move, so that the movable sealing plate 20 slides on the two support rods 26, and then squeezes the two return springs 27. The two movable sealing plates 20 are moved in the above manner. When the argon gas inside the gas cylinder 6 connected to the third cavity 18 is insufficient, the movable sealing plate 20 and the rubber sealing plug 21 will be reset by the elastic force of the two return springs 27, so that the rubber sealing plug 21 is pressed against the third cavity 18. The docking mouth 5 on the three cavities 18 is sealed, and when the movable sealing plate 20 moves, the movable sealing plate 20 squeezes the connecting plate 19 inside the third cavity 18, thereby moving the two push rods 8 and the two push plates 9, and then the two sliding push rods 11 slide along the inclined surfaces of the two tilting drive grooves 10, so that the two insertion rods 13 move away from each other, and squeeze the two first elastic springs 15, thereby disengaging the two insertion rods 13 from the two insertion holes 12, and then the movable base 7 is reset by the tension of the tension spring 33, and then the movable base 7 is moved to the outside of the storage box 2.

[0040] When the argon gas inside the gas cylinder 6 connected to the interior of the second cavity 17 is insufficient, the rubber sealing plug 21 inside the second cavity 17 is used to seal the docking nozzle 5 in the same manner, and the gas cylinder 6 is discharged.

[0041] When the movable sealing plate 20 inside the third cavity 18 is reset, the movable sealing plate 20 will squeeze the pushing handle 30, and the pushing handle 30 will drive the valve stem 37 to rotate, thereby causing the torsion spring 38 to deform, and at the same time, the valve stem 37 will drive the valve ball 36 to rotate, thereby opening the connecting pipe 29, and allowing the argon gas inside the second cavity 17 to enter the third cavity 18 through the connecting pipe 29, and then enter the first cavity 16 and the argon delivery pipe 4, thereby delivering argon gas.

[0042] When the extrusion protrusion 28 follows the movable sealing plate 20 to return to its original position, the extrusion protrusion 28 will squeeze the inclined surface of the blocking rod 23, thereby causing the blocking rod 23 and the square rod 24 to move and squeeze the second elastic spring 25, and then when the extrusion protrusion 28 contacts the other inclined surface of the blocking rod 23, the blocking rod 23 will be reset by the elastic force of the second elastic spring 25, thereby causing the blocking rod 23 to squeeze the extrusion protrusion 28, thereby fixing the movable sealing plate 20, and then when the newly replaced gas cylinder bottle 6 is injected into the docking nozzle 5, the rubber sealing plug 21 and the movable sealing plate 20 are blocked by the blocking rod 23 and cannot be reset, thereby preventing the argon gas inside the gas cylinder bottle 6 from entering the interior of the third cavity 18, and when the gas cylinder bottle 6 connected to the second cavity 17 has no argon gas, the movable sealing plate 20 inside the second cavity 17 will be reset, The cam 32 is pressed against the push rod 31 to release the force from the push handle 30, and the push handle 30 is reset by the torsion spring 38, thereby resetting the valve ball 36 and sealing the valve ball 36 to the connecting pipe 29.

[0043] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the scope of the present invention.
