Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of welding, in particular to a metal material welding mechanism. BACKGROUND

[0002] Arc welding, also known as argon gas shielded welding, is a welding technology using argon as a protective gas. It is a welding technology that uses argon to protect the metal welding material and melts the welding material on the base material to form a molten pool through high current, so that the welded metal and the welding material are metallurgically combined. It is a welding technology that isolates air from the welding area by passing argon gas around the arc to prevent oxidation of the welding area. There are pulse argon arc welding, manual tungsten electrode argon arc welding, etc. The argon arc welding technology prevents the oxidation of the welding material by continuously supplying argon gas during high-temperature melting welding, so that the welding material cannot come into contact with the oxygen in the air. Therefore, stainless steel, iron hardware, and other metals can be welded.

[0003] During the welding of metal materials, argon arc welding is usually used. However, some existing argon arc welding machines are directly connected to a tank containing argon gas. However, as the tank is used for a long time, the amount of argon gas inside the tank decreases, and the amount of argon gas sprayed decreases when welding. As a result, the amount of argon gas in the welding area is not enough, and the welding area lacks the protection of argon gas, which affects the welding effect.

[0035] The rubber sealing pads are arranged, so that the butt joints 5 and the gas cylinder bottles 6 are sealed, the leakage is prevented, and the sealing performance of the device is improved.

[0036] The two butt joints 5 are fixedly installed with the thimbles 35 respectively.

[0037] The two thimbles 35 are arranged, so that when the gas cylinder bottles 6 are butt-jointed with the butt joints 5, the thimbles 35 extrude the sealing valves on the gas cylinder bottles 6, and the argon gas in the gas cylinder bottles 6 is discharged from the inside of the gas cylinder bottles 6.

[0038] The inside of the ventilation block 3 is slidably connected with four push rods 8, the four push rods 8 are penetrated into the inside of the second cavity 17 and the third cavity 18 in two groups respectively, the two groups of push rods 8 are fixedly installed with connecting plates 19, the four push rods 8 are fixedly installed with push plates 9, the four push plates 9 are provided with tilt driving grooves 10, the tilt driving grooves 10 are inclined, the inside of the storage box 2 is fixedly installed with four fixed seats 14, the inside of the four fixed seats 14 are slidably connected with insertion rods 13, one end of the four insertion rods 13 are inclined, the other end of the four insertion rods 13 are fixedly installed with first elastic springs 15, the four first elastic springs 15 are fixedly connected with the four insertion rods 13 respectively, the four insertion rods 13 are fixedly installed with sliding push rods 11, the four sliding push rods 11 are slidably connected in the four tilt driving grooves 10 respectively, the two movable bases 7 are provided with two insertion holes 12 respectively, the four insertion rods 13 are clamped in the four insertion holes 12 respectively.

[0039] When the movable base 7 moves to the outside of the storage box 2, the gas cylinder bottle 6 is put into the inside of the movable base 7, then the movable base 7 is pushed to move, the movable base 7 slides on the two support limiting rods 34 and stretches the tension spring 33, when the two insertion rods 13 contact with the movable base 7, the movable base 7 will extrude the inclined surface of the two insertion rods 13, then the two insertion rods 13 move away from each other, the two insertion rods 13 slide in the two fixed seats 14 and extrude the two first elastic springs 15, at the same time, the two sliding push rods 11 extrude the inner wall of the two tilt driving grooves 10, then the two push plates 9 move, 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, then the two insertion rods 13 are inserted into the inside of the two insertion holes 12, the movable base 7 is fixed, the gas cylinder bottle 6 is connected with the connecting nozzle 5, the two movable bases 7 are fixed in the same way, the gas cylinder bottle 6 and the movable base 7 are fixed, then the safety of the gas cylinder bottle 6 in use is improved, the leakage phenomenon is prevented.

[0040] The inside of the connecting pipeline 29 is rotatably connected with a valve rod 37, one end of the valve rod 37 fixedly installed with a valve ball 36 in the inside of the connecting pipeline 29, the valve ball 36 rotates in the inside of the connecting pipeline 29, the upper end of the valve rod 37 is fixedly installed with a push handle 30, the surface of the valve rod 37 movably sleeved with a torsion spring 38, the upper end of the torsion spring 38 is fixedly connected with the push handle 30, the lower end of the torsion spring 38 is fixedly connected with the connecting pipeline 29.

[0041] The exhaust valves on the two gas cylinder bottles 6 are opened by extrusion of the two ejectors 35, and the argon gas inside the two gas cylinder bottles 6 enters the interiors of the second cavity 17 and the third cavity 18 through the two butt-joint nozzles 5. Since the second cavity 17 and the third cavity 18 are communicated through the connecting pipeline 29, and the connecting pipeline 29 is sealed by the valve ball 36, the argon gas in the second cavity 17 cannot enter the interior of the third cavity 18. The argon gas in the third cavity 18 enters the interior of the first cavity 16 through the connecting hole 22, and then enters the interior of the argon gas delivery pipeline 4. Since the argon gas delivery pipeline 4 is connected with the argon gas pipeline on the argon arc welding machine 1, the argon gas enters the interior of the argon arc welding machine 1, and the argon gas delivery to the argon arc welding machine 1 is realized.

[0042] The interiors of the second cavity 17 and the third cavity 18 are fixedly installed with two support rods 26. The two movable sealing plates 20 are slidably connected on the four support rods 26. The two rubber sealing plugs 21 are fixedly installed on the two movable sealing plates 20. The two rubber sealing plugs 21 are respectively butt-jointed with the two butt-joint nozzles 5. The four reset springs 27 are movably sleeved on the four support rods 26. The four reset springs 27 are respectively fixedly connected with the interiors of the third cavity 18 and the second cavity 17. The ends of the four reset springs 27 close to the two movable sealing plates 20 are respectively fixedly connected with the two movable sealing plates 20.

[0043] In the initial state, the two rubber sealing plugs 21 are inserted into the interiors of the two butt-joint nozzles 5. When the argon gas in the gas cylinder bottle 6 enters the interior of the butt-joint nozzle 5, the argon gas is pushed to move the rubber sealing plug 21 and the movable sealing plate 20, so that the movable sealing plate 20 slides on the two support rods 26, and then extrudes the two reset springs 27. The two movable sealing plates 20 are moved in the above manner. When the argon gas in the gas cylinder bottle 6 connected with the third cavity 18 is insufficient, the movable sealing plate 20 and the rubber sealing plug 21 are reset by the elastic force of the two reset springs 27, so that the rubber sealing plug 21 seals the butt-joint nozzle 5 on the third cavity 18. When the movable sealing plate 20 moves, the movable sealing plate 20 extrudes the connecting plate 19 in the third cavity 18, so that the two push rods 8 move, the two push plates 9 move, the two sliding push rods 11 slide along the inclined surfaces of the two pouring driving grooves 10, the two insertion rods 13 move away from each other, the two insertion rods 13 extrude the two first elastic springs 15, the two insertion rods 13 are separated from the two insertion holes 12, the movable base 7 is reset by the pulling force of the tension spring 33, and then the movable base 7 moves to the outside of the storage box 2.

[0044] When the argon inside the gas tank bottle 6 in communication with the second cavity 17 is insufficient, the rubber sealing plug 21 inside the second cavity 17 is sealed against the butt joint nozzle 5 in the same way, and the gas tank bottle 6 is discharged, which reminds the staff that the argon inside the gas tank bottle 6 is consumed, and then reminds the staff to replace the gas tank bottle 6 in time, improves the convenience of replacing the gas tank bottle 6, and avoids poor effect when welding metal due to the gas tank bottle 6 not being replaced in time.

[0045] When the moving sealing plate 20 inside the third cavity 18 is reset, the moving sealing plate 20 will extrude the push handle 30, and then the push handle 30 will drive the valve rod 37 to rotate, and then the torsion spring 38 will be deformed, and at the same time the valve rod 37 will drive the valve ball 36 to rotate, and then the connecting pipeline 29 will be opened, and then the argon inside the second cavity 17 will enter the inside of the third cavity 18, and then enter the inside of the first cavity 16 and the argon conveying pipeline 4, and then convey the argon, avoid poor welding effect due to insufficient argon, facilitate alternating replacement or use of the gas tank bottle 6, always keep sufficient argon, and improve the welding effect of metal materials.

[0046] The inside of the air exchange block 3 is slidably connected with a square rod 24, one end of the square rod 24 is located inside the second cavity 17, the other end of the square rod 24 is located inside the third cavity 18, the end of the square rod 24 located inside the third cavity 18 is fixedly installed with a blocking rod 23, the square rod 24 is movably sleeved with a second elastic spring 25, one end of the second elastic spring 25 close to the blocking rod 23 is fixedly connected with the blocking rod 23, the other end of the second elastic spring 25 away from the blocking rod 23 is fixedly connected with the inner wall of the third cavity 18, the moving sealing plate 20 inside the third cavity 18 is fixedly installed with an extrusion protruding block 28, the moving sealing plate 20 inside the second cavity 17 is fixedly installed with an inclined guide plate 32, and the square rod 24 is fixedly installed with an extrusion protruding rod 31.

[0047] When the extrusion protrusion 28 follows the movement of the sealing plate 20 to reset, the extrusion protrusion 28 will extrude the inclined surface of the blocking rod 23, and then the blocking rod 23 and the square rod 24 will move and extrude 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 reset through the elastic force of the second elastic spring 25, and then the blocking rod 23 will extrude the extrusion protrusion 28, and then the moving sealing plate 20 will be fixed, and then the newly replaced gas tank bottle 6 cannot reset the rubber sealing plug 21 and the moving sealing plate 20 when injecting argon into the butt joint nozzle 5, and then the argon in the gas tank bottle 6 cannot enter the third cavity 18. When the gas tank bottle 6 connected with the second cavity 17 has no argon, the moving sealing plate 20 in the second cavity 17 will reset, the inclined guide plate 32 will contact the extrusion protrusion 31, and then the extrusion protrusion 31 will move along the inclined surface of the inclined guide plate 32. Because the inclined plate on the inclined guide plate 32 protrudes, the extrusion protrusion 31 will not contact the inclined guide plate 32. When the extrusion protrusion 31 contacts the inclined guide plate 32, the inclined guide plate 32 will provide a pulling force to the extrusion protrusion 31, and then the square rod 24 will slide in the gas exchange block 3, and the blocking rod 23 will extrude the second elastic spring 25, so that the blocking rod 23 will not block the moving sealing plate 20 in the third cavity 18. Then the argon will extrude the moving sealing plate 20 in the third cavity 18, so that the moving sealing plate 20 will not extrude the push handle 30, and the push handle 30 will reset through the torsion spring 38, and then the valve ball 36 will reset, and then the valve ball 36 will seal the connecting pipeline 29, so as to realize the sealing of the connecting pipeline 29, and then it is convenient to consume the argon in the gas tank bottle 6 one by one, so as to prevent the argon in the gas tank bottle 6 from being not consumed, and two gas tank bottles 6 have no argon at the same time, and the convenience of using the device is improved.

[0048] When initially installed, the moving sealing plate 20 in the second cavity 17 is pushed by the external ram, and then the gas tank bottle 6 on the third cavity 18 is installed, and then the moving sealing plate 20 in the second cavity 17 is not stirred, so that the moving sealing plate 20 resets and opens, and then the gas tank bottle 6 on the second cavity 17 is installed, so as to realize the initial installation.

[0049] Working principle:

[0050] When the mobile base 7 moves to the outside of the storage box 2, the gas cylinder bottle 6 is put into the inside of the mobile base 7, and then the mobile base 7 is pushed to move, so that the mobile base 7 slides on the two support limiting rods 34 and stretches the tension spring 33. When the two insertion rods 13 contact the mobile base 7, the mobile base 7 will extrude the inclined surface of the two insertion rods 13, so that the two insertion rods 13 move away from each other, slide in the two fixed seats 14, extrude the two first elastic springs 15, and extrude the inner wall of the two inclined driving grooves 10, so that the two push plates 9 move. When the two insertion rods 13 coincide with the two insertion holes 12, the two insertion rods 13 will be reset by the elastic force of the two first elastic springs 15, so that the two insertion rods 13 are inserted into the inside of the two insertion holes 12, the fixing of the mobile base 7 is completed, the gas cylinder bottle 6 is connected with the connecting nozzle 5, and the two mobile bases 7 are fixed in the same way, which is convenient for fixing the gas cylinder bottle 6 and the mobile base 7.

[0051] The exhaust valves on the two gas cylinder bottles 6 are opened by extruding the two thimbles 35, so that the argon gas in the two gas cylinder bottles 6 enters into the inside of the second cavity 17 and the third cavity 18 through the two connecting nozzles 5. Since the second cavity 17 and the third cavity 18 are communicated through the connecting pipeline 29, and the connecting pipeline 29 is sealed by the valve ball 36, the argon gas in the second cavity 17 cannot enter into the inside of the third cavity 18. The argon gas in the third cavity 18 enters into the inside of the first cavity 16 through the connecting hole 22, and then enters into the inside of the argon gas conveying pipeline 4. Since the argon gas conveying pipeline 4 is connected with the argon gas pipeline on the argon arc welding machine 1, the argon gas enters into the inside of the argon arc welding machine 1, so that the argon gas conveying of the argon arc welding machine 1 is realized.

[0052] The two rubber sealing plugs 21 are inserted into the two docking nozzles 5 in the initial state. When the argon gas in the gas cylinder 6 is discharged into the docking nozzles 5, the discharged argon gas pushes the rubber sealing plugs 21 and the movable sealing plate 20 to move, so that the movable sealing plate 20 slides on the two supporting rods 26 and presses the two return springs 27. The two movable sealing plates 20 move in the same way. When the argon gas in the gas cylinder 6 connected to the third cavity 18 is insufficient, the movable sealing plate 20 and the rubber sealing plug 21 are reset by the elastic force of the two return springs 27, so that the rubber sealing plug 21 seals the docking nozzle 5 on the third cavity 18. When the movable sealing plate 20 moves, the movable sealing plate 20 presses the connecting plate 19 in the third cavity 18, so that the two push rods 8 move, the two push plates 9 move, the two sliding push rods 11 slide along the inclined surface of the two pouring driving grooves 10, the two insertion rods 13 move away from each other and press the two first elastic springs 15, so that the two insertion rods 13 are separated from the two insertion holes 12, the movable base 7 is reset by the pulling force of the tension spring 33, and the movable base 7 moves to the outside of the storage box 2.

[0053] When the argon gas in the gas cylinder 6 connected to the second cavity 17 is insufficient, the rubber sealing plug 21 in the second cavity 17 seals the docking nozzle 5 in the same way, and the gas cylinder 6 is discharged.

[0054] When the movable sealing plate 20 in the third cavity 18 is reset, the movable sealing plate 20 presses the push handle 30, so that the push handle 30 drives the valve rod 37 to rotate, the torsion spring 38 is deformed, the valve rod 37 drives the valve ball 36 to rotate, the connecting pipeline 29 is opened, the argon gas in the second cavity 17 enters the third cavity 18, and the argon gas in the first cavity 16 and the argon gas conveying pipeline 4 is conveyed.

[0055] In the extrusion protrusion 28 follow the movement of the sealing plate 20 reset, will make the extrusion protrusion 28 to the slope of the blocking rod 23 extrusion, and then make the blocking rod 23 and square rod 24 movement, and extrusion to the second elastic spring 25, and then that extrusion protrusion 28 and the other slope of the blocking rod 23 contact, will make the blocking rod 23 reset through the elastic force of the second elastic spring 25, and then make the blocking rod 23 extrusion to the extrusion protrusion 28, and then fixed to the movement of the sealing plate 20, and then the new replacement of the gas tank bottle 6 in the butt joint nozzle 5 inside the injection of argon rubber sealing plug 21 and the movement of the sealing plate 20 blocked by the blocking rod 23 can not reset, and then make the argon gas in the gas tank bottle 6 can not enter the third cavity 18 inside, when the gas tank bottle 6 with the second cavity 17 communication has no argon gas, will make the movement of the sealing plate 20 inside the second cavity 17 reset, will make the inclined guide plate 32 and extrusion protrusion 31 contact, and then make the extrusion protrusion 31 along the slope of the inclined guide plate 32 movement and then due to the inclined guide plate 32 on the slope protrusion, and then make the extrusion protrusion 31 through the inclined guide plate 32 not in contact with the inclined guide plate 32, in the extrusion protrusion 31 and the inclined guide plate 32 contact, will make the inclined guide plate 32 to the extrusion protrusion 31 a pulling force, and then make the square rod 24 in the gas block 3 inside the sliding, and make the blocking rod 23 to the second elastic spring 25 extrusion, make the blocking rod 23 not in the third cavity 18 inside the movement of the sealing plate 20 blocking, and then the argon gas to the third cavity 18 inside the movement of the sealing plate 20 extrusion, and then make the movement of the sealing plate 20 not in contact with the push handle 30 extrusion, make the push handle 30 reset through the torsion spring 38, and then make the valve ball 36 reset, and then make the valve ball 36 to the connecting pipeline 29 sealing.

[0056] The above embodiments of the present application are described in detail in conjunction with the drawings, but the present application is not limited to the above embodiments, within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present application.
