Description

Technical Field

[0001] This application relates to the field of manufacturing gas storage tanks, and in particular to a fully automatic circumferential welding equipment for gas storage tanks. Background Technology

[0002] A gas storage tank is a device specifically designed to store gas and also serves to stabilize system pressure. A gas storage tank consists of a cylindrical body and two covers. The two covers are fixed to both ends of the cylindrical body's axis and seal the inner cavity of the cylinder, thus completing the manufacturing process of the gas storage tank.

[0003] During the processing of gas storage tanks, workers need to hold a welding torch and rotate the cylinder to weld and fix the circumferential seam at the connection between the cover and the cylinder, thus completing the processing of the gas storage tank. The workers perform this single processing action for extended periods, prolonging the production cycle of the gas storage tanks and increasing their production costs. Summary of the Invention

[0004] To address the issue of reduced production costs for gas storage tanks, this application provides a fully automated circumferential welding device for gas storage tanks.

[0005] This application provides a fully automatic circumferential welder for gas storage tanks, which adopts the following technical solution: An automated circumferential welding device for gas storage tanks includes a machine body, a positioning device, and a welding assembly. The positioning device includes two power components, two movable seats, and two rotating disks. The two movable seats are slidably connected to the machine body at intervals. The power components and movable seats correspond one-to-one and are connected. The rotating disks correspond one-to-one with the power components and are connected to the driving end of the power components. The two rotating disks face each other and their axes coincide. The welding assembly is connected to the machine body. The welding end of the welding assembly can perform circumferential welding to fix the connection between the cover and the cylinder. When the gas storage tank is placed between the two movable seats, the two movable seats move closer to each other. The rotating disks correspond one-to-one with the cover and abut against it. The power components drive the rotating disks to rotate and drive the gas storage tank to rotate around its own axis. The welding end of the welding assembly abuts against the connection between the cover and the cylinder and fixes it with circumferential welding.

[0006] By adopting the above technical solution, during the processing of the gas storage tank, the worker places the gas storage tank between two movable seats, which are close to each other. The rotating disk corresponds to and abuts the cover. The welding end of the welding component abuts the connection between the cover and the cylinder. The power component drives the rotating disk to rotate and causes the gas storage tank to rotate around its own axis. The welding end of the welding component performs circumferential welding to fix the connection between the cover and the cylinder. There is no need for the worker to hold the welding gun and rotate the cylinder to fix the circumferential welding at the connection between the cover and the cylinder. This realizes the fully automatic circumferential welding processing of the gas storage tank, shortens the production cycle of the gas storage tank, and thus reduces the production cost of the gas storage tank.

[0007] Optionally, the positioning device further includes a positioning assembly, which includes a positioning cylinder and a positioning plate. The positioning cylinder is connected to the machine body, and the piston rod axis of the positioning cylinder is parallel to the height direction of the machine body. The positioning plate is connected to the piston rod of the positioning cylinder, and the surface of the positioning plate has a positioning cavity for the air tank to be embedded. When the air tank is located in the positioning cavity, the positioning cylinder drives the positioning plate away from the machine body, and the axis of the air tank coincides with the axis of the rotating disk.

[0008] By adopting the above technical solution, when the gas tank is placed in the positioning cavity, the positioning cylinder drives the positioning plate to move away from the machine body, the axis of the gas tank and the axis of the rotating disk coincide, the two moving seats move towards each other, the rotating disk and the cover are pressed together in a corresponding manner, and the axis of the rotating disk and the axis of the gas tank coincide. There is no need for the staff to repeatedly adjust the position between the rotating disk and the cover, which further reduces the workload of the staff, improves the production efficiency of the gas tank, and thus reduces the production cost of the gas tank.

[0009] Optionally, a feeding device is also included, which includes a transport component and a mechanical gripper. The transport component is connected to the machine body and can drive the gas storage tank close to the positioning plate. The mechanical gripper is connected to the machine body and can hold the gas storage tank on the transport component and place it in the positioning cavity.

[0010] By adopting the above technical solution, the transport component drives the gas tank close to the positioning plate, and the mechanical gripper clamps the gas tank on the transport component and places it in the positioning cavity, realizing automatic feeding of the gas tank in the positioning cavity. There is no need for staff to move the gas tank to the vicinity of the machine and place it in the positioning cavity, which reduces the workload of the staff, shortens the production cycle of the gas tank, and thus reduces the production cost of the gas tank.

[0011] Optionally, a feeding device is also included, comprising a conveying assembly, a feeding cylinder, and a guide plate. The conveying assembly is capable of transporting the air tank. The guide plate is connected to the machine body, and the inclination height of the guide plate decreases as the distance to the conveying assembly decreases. The guide plate surface faces the conveying end face of the conveying assembly. The feeding cylinder is connected to the machine body, and the piston rod axis of the feeding cylinder and the piston rod axis of the positioning cylinder are perpendicular to each other. The end of the piston rod of the feeding cylinder is connected to the surface of the positioning cylinder. The feeding cylinder can drive the positioning cylinder to approach the guide plate along the surface of the machine body. The air tank in the positioning cavity can enter the conveying end face of the conveying assembly along the guide plate surface.

[0012] By adopting the above technical solution, when the circumferential weld of the gas storage tank is completed, the positioning cylinder drives the positioning plate to move towards the gas storage tank, and the gas storage tank is embedded in the positioning cavity. The unloading cylinder drives the positioning cylinder to approach the guide plate, and the surface of the guide plate abuts against the surface of the gas storage tank in the positioning cavity. At the same time, the tilt height of the guide plate decreases as the distance to the conveying component decreases. The gas storage tank in the positioning cavity is guided to enter the conveying end face of the conveying component along the surface of the guide plate, realizing the automatic unloading of the gas storage tank. There is no need for workers to handle the gas storage tank after the circumferential weld is completed, which further reduces the production cycle of the gas storage tank and thus reduces the production cost of the gas storage tank.

[0013] Optionally, multiple positioning cavities are provided, and the arrangement direction of the positioning cavities is parallel to the axis of the piston rod of the feeding cylinder. When the feeding cylinder drives the positioning cylinder to approach the guide plate, the air tank in the positioning cavity near the guide plate enters the conveying end face of the conveying assembly along the guide plate surface, and the two rotating disk surfaces abut against the two ends of the air tank in the adjacent positioning cavity to form a positioning.

[0014] By adopting the above technical solution, when the welding assembly completes the circumferential welding of the gas tank, the positioning cylinder drives the positioning plate away from the machine body, and the gas tank with the circumferential welded is embedded in the positioning cavity. At the same time, the mechanical gripper clamps the gas tank on the transport assembly and places it in the positioning cavity near the transport assembly. Meanwhile, the unloading cylinder drives the positioning cylinder to approach the guide plate, driving the welded gas tank to enter the conveying end face of the conveying assembly along the guide plate surface. At the same time, the gas tanks in adjacent positioning cavities are clamped one by one by the rotating disk, realizing the synchronous loading and unloading of the gas tanks.

[0015] Optionally, a clamping assembly is connected to the rotating disk. The clamping assembly includes a clamping ring bladder and a clamping piston. A sliding cavity is provided on the surface of the rotating disk for the clamping piston to slide. The end of the clamping piston protruding from the rotating disk can abut against the surface of the gas storage tank. The clamping ring bladder is connected to the opposite end faces of the rotating disk. The inner cavity of the clamping ring bladder is connected to the sliding cavity. The surface of the clamping ring bladder can be pressurized and expanded to abut against the surface of the gas storage tank.

[0016] By adopting the above technical solution, the clamping ring is connected to the surface of the rotating disk facing the gas tank. When the two moving seats approach each other, the outer wall of the gas tank abuts against the surface of the clamping piston and drives the clamping piston to slide towards the sliding cavity. The air pressure in the sliding cavity increases, and the air in the sliding cavity enters the inner cavity of the clamping ring. The inner cavity of the clamping ring expands under pressure, and the surface of the clamping ring presses against the surface of the gas tank to form a limit, making it less likely for the gas tank to deviate on the surface of the rotating disk, thereby improving the stability of the rotation of the gas tank.

[0017] Optionally, the clamping assembly further includes a reset elastic element, one end of which is connected to the inner wall of the sliding cavity in the direction of elastic force, and the other end of which is connected to the surface of the clamping piston in the direction of elastic force. The reset elastic element has the elastic force to drive the clamping piston to slide away from the sliding cavity, and the end of the clamping piston protrudes from the surface of the rotating disk.

[0018] By adopting the above technical solution, when the two moving seats slide away from each other, the surface of the gas tank detaches from the surface of the rotating disk, causing the gas tank to lose its clamping effect on the clamping piston. One end of the reset elastic element in the direction of its elastic force is connected to the inner wall of the sliding cavity, and the other end of the reset elastic element in the direction of its elastic force is connected to the surface of the clamping piston. The elastic force of the reset elastic element drives the clamping piston to slide away from the sliding cavity. The end of the clamping piston protrudes from the end face of the rotating disk, realizing the automatic reset of the clamping piston. There is no need for the staff to manually slide the clamping piston, further reducing the workload of the staff, shortening the production cycle of the gas tank, and thus reducing the production cost of the gas tank.

[0019] Optionally, a cooling fan is rotatably connected to the movable base, with the air outlet of the cooling fan facing the rotating disk surface.

[0020] By adopting the above technical solution, the cooling fan rotates on the surface of the moving base, and the air outlet of the cooling fan faces the rotating disk surface. The rotating disk surface presses against the surface of the gas storage tank and drives the gas storage tank to rotate around its own axis. After the rotating disk has been running for a long time, part of the kinetic energy of the rotating disk is converted into its own heat energy. The cooling fan drives the air from the air outlet to impact the rotating disk surface, and the rotating disk exchanges heat with the air to cool down the rotating disk. This makes the rotating disk less likely to be damaged due to prolonged operation at high temperatures, thereby extending the service life of the fully automatic circumferential welding equipment for the gas storage tank.

[0021] Optionally, a conductive assembly connects the rotating disk and the cooling fan. The conductive assembly includes a first bevel gear, a second bevel gear, a conductive rod, two conductive wheels, and a conductive belt used in conjunction with the conductive wheels. The conductive rod is rotatably connected to the surface of the movable seat, and the rotation axis of the conductive rod is parallel to the rotation axis of the rotating disk. The first bevel gear is coaxially connected to the rotating shaft of the cooling fan, and the second bevel gear is coaxially connected to the conductive rod. The first bevel gear meshes with the second bevel gear. One of the conductive wheels is coaxially connected to the conductive rod, and the other conductive wheel is coaxially connected to the rotating shaft of the rotating disk. The conductive belt tensions and connects the two conductive wheels.

[0022] By adopting the above technical solution, when the rotating disk rotates, one of the transmission wheels is coaxially connected to the transmission rod, and the other transmission wheel is coaxially connected to the rotating shaft of the rotating disk. The transmission belt tensions and connects the two transmission wheels, driving the transmission rod to rotate on the moving seat. The first bevel gear is coaxially connected to the rotating shaft of the cooling fan, and the second bevel gear is coaxially connected to the transmission rod. The first bevel gear meshes with the second bevel gear, driving the cooling fan to rotate. No external power equipment is needed to drive the cooling fan to rotate, reducing energy consumption and embodying the concept of energy saving.

[0023] Optionally, a directional ring is connected to the surface of the conduction wheel on the rotating disk. The outer ring of the directional ring abuts against the surface of the conduction belt. A directional flow channel is formed in the inner wall of the sliding cavity. The directional flow channel penetrates the outer wall of the rotating disk and connects to the inner cavity of the directional ring. A sealing plate is slidably connected to the inner wall of the sliding cavity near the directional flow channel. The surface of the sealing plate abuts against the opening of the directional flow channel and separates the directional flow channel and the sliding cavity. A thermal expansion and contraction block is connected to the inner wall of the sliding cavity. The end of the thermal expansion and contraction block is connected to the surface of the sealing plate. When the thermal expansion and contraction block heats up and expands, it drives the sealing plate to slide away from the directional flow channel, and the separation effect between the directional flow channel and the sliding cavity disappears.

[0024] By adopting the above technical solution, when the rotating disk heats up, the thermal expansion and contraction block heats up and expands, driving the sealing plate to slide away from the directional flow channel, so that the separation effect between the directional flow channel and the sliding cavity disappears. The air in the sliding cavity enters the inner cavity of the directional ring bag through the directional flow channel, the directional ring bag is pressurized and expands, the outer ring of the directional ring bag expands and presses against the surface of the conduction belt, so that the conduction belt stably transmits the power of the rotating disk to the rotating rod, thereby ensuring the stability of the cooling fan operation.

[0025] In summary, this application includes at least one of the following beneficial technical effects: The setup of the power unit, moving seat, and rotating plate allows the welding end of the welding assembly to perform circumferential welding and fixation at the connection between the cover and the cylinder. This eliminates the need for workers to hold a welding gun and rotate the cylinder to perform circumferential welding and fixation at the connection between the cover and the cylinder, thus achieving fully automated circumferential welding of the gas storage tank, shortening the production cycle of the gas storage tank, and reducing the production cost of the gas storage tank. The positioning cylinder and positioning plate are set up so that the rotating disk and the cover are in one-to-one correspondence and abut against each other, and the axis of the rotating disk and the axis of the air tank are coincident. This eliminates the need for staff to repeatedly adjust the position between the rotating disk and the cover, further reducing the workload of staff, improving the production efficiency of the air tank, and thus reducing the production cost of the air tank. The transport components and mechanical grippers enable automatic feeding of the gas tanks in the positioning cavity, eliminating the need for workers to move the gas tanks to the vicinity of the machine and place them in the positioning cavity. This reduces the workload for workers, shortens the production cycle of the gas tanks, and thus reduces the production cost of the gas tanks. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses a fully automated circumferential welder for gas storage tanks. (Refer to...) Figure 1 and Figure 2 The fully automatic circumferential welding equipment for gas storage tanks includes a machine body 1, a positioning device 2, a welding assembly 3, a feeding device 4, and a discharging device 5.

[0033] Reference Figure 1 and Figure 2 The feeding device 4 includes a transport component 41 and a mechanical gripper 42. The transport component 41 includes a transport motor, two sprockets, and a chain used in conjunction with the sprockets. The two sprockets are rotatably connected at both ends of the machine body 1 along its length. The chain is tensioned to connect the two sprockets. The end face of the chain is for placing the gas storage tank. The transport motor is fixed to the outer wall of the machine body 1 by bolts. The motor shaft of the transport motor is coaxially welded and fixed to one of the sprockets. The transport motor drives the sprocket to rotate, which moves the gas storage tank on the chain closer to the positioning device 2. The mechanical gripper 42 is connected to the surface of the machine body 1. The gripping end of the mechanical gripper 42 faces the end face of the chain. The gripping end of the mechanical gripper 42 can grip the gas storage tank on the end face of the chain and place it on the positioning device 2, thereby realizing the automatic feeding of the gas storage tank on the positioning device 2.

[0034] Reference Figure 2 and Figure 3 The number of positioning devices 2 can be one, two, or more. In this embodiment, the number of positioning devices 2 is multiple. The arrangement direction of the positioning devices 2 is parallel to the length direction of the machine body 1. The positioning device 2 includes a positioning assembly 21, two drive cylinders 22, two power components 23, two moving seats 24, and two rotating disks 25.

The moving seats 24 and the drive cylinders 22 are paired one-to-one. The movable seat 24 is fixed on the piston rod of the drive cylinder 22. The drive cylinder 22 drives the movable seat 24 to slide along the surface of the machine body 1. The sliding direction of the movable seat 24 is parallel to the length direction of the machine body 1. In this embodiment, the power component 23 is a motor. The power component 23 and the movable seat 24 correspond one-to-one. The power component 23 is fixed to the surface of the movable seat 24 by bolts. The rotating disk 25 corresponds one-to-one with the power component 23. The rotating disk 25 is connected to the drive end of the power component 23. The end faces of the two rotating disks 25 can press against the outer wall of the gas storage tank, and the rotation axes of the two rotating disks 25 coincide.

[0035] Reference Figure 3 The positioning component 21 is used to place the gas storage tank held by the mechanical gripper 42 and move the gas storage tank between the two rotating disks 25. The positioning component 21 includes a positioning cylinder 211 and a positioning plate 212. The positioning cylinder 211 is connected to the machine body 1. The piston rod axis of the positioning cylinder 211 is parallel to the height direction of the machine body 1. The positioning plate 212 is fixed on the piston rod of the positioning cylinder 211. The end face of the positioning plate 212 opposite to the positioning cylinder 211 has a positioning cavity 2121 for the gas storage tank to be embedded. The number of positioning cavities 2121 can be one, two or more. In this embodiment, the number of positioning cavities 2121 is multiple.

[0036] Reference Figure 2 and Figure 3The mechanical gripper 42 clamps the air tank at the end of the chain and places it in the positioning cavity 2121. The positioning cylinder 211 drives the positioning plate 212 to slide away from the machine body 1. The axis of the air tank and the axis of the rotating disk 25 coincide. The driving cylinder 22 drives the moving seat 24 to approach the positioning plate 212. The surface of the rotating disk 25 presses against the outer wall of the air tank to form a limit. The power component 23 runs and drives the rotating disk 25 to rotate, causing the rotating disk 25 to rotate around its own axis, thereby realizing the automated rotation of the rotating disk 25.

[0037] Reference Figure 2 The number of welding components 3 can be one, two, or more. In this embodiment, the number of welding components 3 is two. The welding components 3 and the positioning device 2 correspond one-to-one. The welding components 3 include two welding guns 31, two welding motors 32, two reciprocating lead screws 33, and two welding cylinders 34. The two welding motors 32 are fixed to the outer wall of the machine body 1 by bolts at intervals. The motor axis of the welding motors 32 is parallel to the length direction of the machine body 1, and the motor shafts of the welding motors 32 are directly opposite each other. The reciprocating lead screws 33 correspond one-to-one with the welding motors 32. The reciprocating lead screws 33 are coaxially welded and fixed to the motor shafts of the welding motors 32. The welding cylinders 34 correspond one-to-one with the reciprocating lead screws 33. The outer wall of the welding cylinders 34 is threaded to the outer wall of the reciprocating lead screws 33. The piston rod axis of the welding cylinders 34 is parallel to the height direction of the machine body 1. The welding guns 31 correspond one-to-one with the welding cylinders 34. The outer wall of the welding guns 31 is connected to the end of the piston rod of the welding cylinders 34. The welding end of the welding guns 31 faces the surface of the positioning plate 212.

[0038] Reference Figure 2 The welding motor 32 drives the welding cylinder 34 to slide along the axis of the reciprocating screw 33. The welding cylinder 34 drives the welding gun 31 to move closer to or away from the positioning plate 212, so as to realize the arbitrary adjustment of the welding end position of the welding gun 31. This allows the welding end of the welding gun 31 to accurately abut against the connection between the cylinder and the cover. When the gas tank rotates around its own axis, the welding gun 31 completes the fully automatic circumferential welding of the gas tank, thus facilitating the completion of circumferential welding of gas tanks of various diameters.

[0039] Reference Figure 2 and Figure 3The feeding assembly includes a conveying assembly 51, a feeding cylinder 52, and a guide plate 53. The conveying assembly 51 includes a conveying frame 511, a conveying motor, two conveying gears, and a conveying chain used in conjunction with the conveying gears.

The end face of the conveying chain is for placing the air storage tank. The conveying motor is fixed to the surface of the conveying frame 511 by bolts. The end of the motor shaft of the conveying motor is coaxially fixed to the rotating shaft of one of the conveying gears. When the conveying motor is running, the conveying chain is tensioned and connected to the two conveying gears, driving the air storage tank at the end face of the conveying chain away from the positioning device 2.

[0040] Reference Figure 2 and Figure 3 The guide plate 53 is welded and fixed to the machine body 1. The surface of the guide plate 53 faces the end face of the conveyor chain. The tilt height of the guide plate 53 decreases as the distance to the conveyor chain decreases. The air tank with the circumferential weld completed can enter the end face of the conveyor chain along the surface of the guide plate 53. The feeding cylinder 52 is fixed to the machine body 1. The piston rod axis of the feeding cylinder 52 and the arrangement direction of the positioning cavity 2121 are parallel to each other. The end of the piston rod of the feeding cylinder 52 is fixed to the outer wall of the positioning cylinder 211. The feeding cylinder 52 can drive the positioning cylinder 211 to approach the guide plate 53.

[0041] Reference Figure 2 and Figure 3 When the circumferential weld of the gas tank is completed, the positioning cylinder 211 drives the positioning plate 212 to slide away from the machine body 1, and the gas tank is embedded in the positioning cavity 2121. The unloading cylinder 52 drives the positioning cylinder 211 to slide towards the guide plate 53, and drives the gas tank in the positioning cavity 2121 to enter the surface of the guide plate 53. The gas tank enters the end face of the conveyor chain along the surface of the guide plate 53, realizing the automatic unloading of the gas tank after the circumferential weld is completed. At the same time, the axis of the gas tank in the adjacent positioning cavity 2121 coincides with the axis of the rotating disk 25. The two moving seats 24 approach each other, driving the two rotating disks 25 to clamp the two ends of the gas tank axis one by one, realizing the automatic clamping of the gas tank on the rotating disk 25, further shortening the processing cycle of the gas tank, thereby reducing the production cost of the gas tank.

[0042] Reference Figure 4A clamping assembly 6 is connected to the rotating disk 25, which can clamp the surface of the gas storage tank. The clamping assembly 6 includes a clamping ring 61, a clamping piston 62, and a reset elastic element 63. The clamping ring 61 can be made of rubber or silicone. In this embodiment, the clamping ring 61 is made of rubber and has a certain deformation capacity. The clamping ring 61 is fixed to the surface of the rotating disk 25 facing the gas storage tank, and the surface of the clamping ring 61 can press against the surface of the gas storage tank. The clamping piston 62 can be made of rubber or silicone. In this embodiment, the clamping piston 62 is made of rubber and has a certain deformation capacity. A sliding cavity 251 is provided on the surface of the rotating disk 25 facing the gas storage tank for the clamping piston 62 to slide. The sliding direction of the clamping piston 62 coincides with the axis of the rotating disk 25, and the sliding cavity 251 is connected to the inner cavity of the clamping ring 61. The reset elastic element 63 can be a compression spring or a tension spring. In this embodiment, the reset elastic element 63 is a compression spring and has a certain deformation capacity. One end of the reset elastic member 63 in the elastic direction is fixed to the inner wall of the sliding cavity 251, and the other end of the reset elastic member 63 in the elastic direction is fixed to the surface of the pressing piston 62. The reset elastic member 63 has the elastic force to drive the pressing piston 62 to slide away from the sliding cavity 251, and the end of the pressing piston 62 protrudes from the surface of the rotating disk 25. The end of the pressing piston 62 protruding from the rotating disk 25 can abut against the surface of the gas storage tank.

[0043] Reference Figure 4 When the two movable seats 24 approach each other, the surface of the gas tank abuts against the surface of the pressing piston 62 and drives the pressing piston 62 to slide towards the sliding cavity 251. The air pressure in the sliding cavity 251 increases, and the air in the sliding cavity 251 enters the inner cavity of the pressing ring 61. The inner cavity of the pressing ring 61 is pressurized and expands and presses against the outer wall of the gas tank, improving the limiting stability of the gas tank on the surface of the rotating disk 25.

[0044] Reference Figure 3 and Figure 4 A cooling fan 7 is rotatably connected to the movable seat 24. The rotation axis of the cooling fan 7 is parallel to the piston rod axis of the positioning cylinder 211. The air outlet of the cooling fan 7 faces the surface of the rotating disk 25. A transmission assembly 8 is connected between the rotating disk 25 and the cooling fan 7. The transmission assembly 8 can receive the power of the rotating disk 25 and drive the cooling fan 7 to rotate. The transmission assembly 8 includes a first bevel gear 81, a second bevel gear 82, a transmission rod 83, two transmission wheels 84, and a transmission belt 85 used in conjunction with the transmission wheels 84. The transmission rod 83 is rotatably connected to the surface of the movable seat 24. The rotation axis of the transmission rod 83 is parallel to the sliding direction of the movable seat 24. The first bevel gear 81 is coaxially welded and fixed to the rotation shaft of the cooling fan 7. The second bevel gear 82 is coaxially welded and fixed to the transmission rod 83. The first bevel gear 81 meshes with the second bevel gear 82. One transmission wheel 84 is coaxially fixed to the outer wall of the transmission rod 83, and the other transmission wheel 84 is coaxially fixed to the rotation shaft of the rotating disk 25. The transmission belt 85 tensions and connects the two transmission wheels 84.

[0045] Reference Figure 4 When the rotating disk 25 rotates, the conduction belt 85 tensions and connects the two conduction wheels 84, driving the conduction rod 83 to rotate. The first bevel gear 81 meshes with the second bevel gear 82, driving the rotating fan to rotate. The rotating fan drives the air to rush the surface of the rotating disk 25, thereby cooling the surface of the rotating disk 25 and preventing the rotating disk 25 from being in a high-temperature state for a long time, thus ensuring the stability of the operation of the rotating disk 25.

[0046] Reference Figure 4 A directional ring bladder 9 is coaxially connected to the surface of a transmission wheel 84 fixed on a rotating disk 25. The material of the directional ring bladder 9 can be rubber or silicone. In this embodiment, the material of the directional ring bladder 9 is rubber, which has a certain deformation capability. The outer ring of the directional ring bladder 9 abuts against the surface of the transmission belt 85. A directional flow channel 252 is opened on the inner wall of the sliding cavity 251 near the transmission wheel 84. The directional flow channel 252 penetrates the outer wall of the rotating disk 25 and connects to the inner cavity of the directional ring bladder 9. A thermal expansion and contraction block 10 is located in front of the inner wall of the sliding cavity 251 near the directional flow channel 252. The material of the thermal expansion and contraction block 10 can be nylon or rubber. In this embodiment, the material of the thermal expansion and contraction block 10 is nylon, which has a certain deformation capability. A sealing plate 11 is fixed to the end face of the thermal expansion and contraction block 10. The surface of the sealing plate 11 abuts against the opening of the directional flow channel 252 and separates the directional flow channel 252 and the sliding cavity 251.

[0047] Reference Figure 4 When the air in the sliding cavity 251 heats up and expands, the thermal expansion and contraction block 10 heats up and expands, driving the sealing plate 11 to slide away from the directional flow channel 252. The sealing effect of the sealing plate 11 on the directional flow channel 252 disappears, and the directional flow channel 252 connects to the sliding cavity 251. The air in the sliding cavity 251 enters the inner cavity of the directional ring 9 through the directional flow channel 252. The outer ring of the directional ring 9 is pressurized and expands, further improving the clamping force between the inner ring of the directional ring 9 and the surface of the conductive belt 85, thereby ensuring the stability of the rotation of the cooling fan 7.

[0048] The implementation principle of the fully automatic circumferential welding equipment for gas storage tanks in this application embodiment is as follows: The transport motor drives the sprocket to rotate, which drives the gas storage tank on the chain to approach the positioning device 2. The mechanical gripper 42 clamps the gas storage tank at the end face of the chain and places it in the positioning cavity 2121. The positioning cylinder 211 drives the positioning plate 212 to slide away from the machine body 1. The axis of the gas storage tank and the axis of the rotating disk 25 coincide. The drive cylinder 22 drives the moving seat 24 to approach the positioning plate 212. The surface of the rotating disk 25 presses against the outer wall of the gas storage tank to form a limit. The power component 23 runs and drives the rotating disk. Rotation of component 25 drives the rotating disk 25 to rotate around its own axis, realizing the automated rotation of the rotating disk 25; at the same time, the welding end of the welding gun 31 precisely abuts against the connection between the cylinder and the cover, and the welding end of the welding gun 31 performs circumferential welding on the connection between the cylinder and the cover, realizing the fully automatic circumferential welding of the gas storage tank by the welding gun 31. There is no need for the operator to hold the welding gun and rotate the cylinder to fix the circumferential welding of the connection between the cover and the cylinder, realizing the fully automatic circumferential welding processing of the gas storage tank, shortening the production cycle of the gas storage tank, thereby reducing the production cost of the gas storage tank.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
