Description

Technical Field

[0001] The present invention relates to the technical field of welding, and particularly to a welding device for the production of a housing for the processing of an air compressor. Background Art

[0002] An air compressor, also known as an air compressor, is a machine that compresses air to increase gas pressure or transport gas. There are three forms of air compressors: piston type, centrifugal type, and screw type. An air compressor is a device for compressing gas similar to the principle of a water pump. By driving the air compressor with an electric motor, the crankshaft inside the air compressor rotates, thereby driving the connecting rod inside to drive the piston to reciprocate, causing a change in the volume inside the cylinder. The air compressor provides the air source power and is the core device of the pneumatic system and the main body of the mechanical and electrical air source device. It is a device that converts the original mechanical energy into gas pressure energy and is the pneumatic pressure generating device of compressed air. The air compressor is one of the mechanical power devices. With the continuous development of technology and the rapid progress of society, the application of air compressors is increasing. When manufacturing an air compressor, the storage tank housing on the air compressor is one of the important components. When processing the storage tank housing, welding work is required, so a welding device is needed.

[0003] Currently, when welding the storage tank housing traditionally, it is inconvenient to adjust the welding tool, resulting in inflexible welding, affecting the welding speed, and the storage tank housing needs to be rolled to weld the gap, making the storage tank housing prone to deviation and inaccurate welding, affecting the welding quality. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A welding device for the production of a housing for the processing of an air compressor, comprising: A machine body, and a frame fixedly installed on the side of the surface of the machine body. A square frame is fixedly connected to the side of the top of the machine body, and a feeding mechanism is installed in the middle of the top of the machine body; A processing mechanism, which is used for welding and processing the storage tank on the air compressor, and the processing mechanism is installed in the middle of the top of the frame; Among them, the processing mechanism includes a hydraulic cylinder and a connecting flat plate. The hydraulic cylinder is installed in the middle of the top of the frame. The connecting flat plate is fixedly connected to the telescopic end of the hydraulic cylinder. A rotary driver is fixedly installed in the middle of the bottom of the connecting flat plate. A welding gun is hinged to the edge of the rotary end of the rotary driver. An electric telescopic rod is hinged to the side of the bottom of the rotary end of the rotary driver. A guiding component is installed on the side of the bottom of the connecting flat plate. By extending and contracting the telescopic end of the hydraulic cylinder, the connecting flat plate can be driven to move downward and upward. Under the connection of the rotary driver, the welding gun is driven to move, so that the height of the welding gun can be adjusted, making the welding end of the welding gun at a suitable height from the air compressor storage tank shell to be welded, which helps to avoid welding the storage tank; The feeding mechanism includes a rotating workbench and a circular limiting hole. The rotating workbench is rotatably installed in the middle of the top of the machine body. The circular limiting hole is opened at the edge of the surface of the rotating workbench. An arc-shaped elastic strip is fixedly connected to the position of the circular limiting hole at the edge of the rotating workbench. A clamping block is fixedly connected to the inner side surface of the arc-shaped elastic strip. A lifting component is installed on the side of the bottom of the rotating workbench.

[0005] Preferably, the telescopic end of the electric telescopic rod is hinged to the surface of the electric telescopic rod. Both the electric telescopic rods are inclined. By applying a pulling force to the welding gun through the telescopic end of the electric telescopic rod, the welding gun can be rotated to adjust the angle. And by extending the telescopic end of the electric telescopic rod, the welding gun can be pushed, so that the welding gun rotates outward, and the angle can be adjusted by the rotation of the welding gun.

[0006] By using the rotary end at the bottom of the rotary driver to rotate, the welding gun can be driven to rotate together, so that the welding gun rotates along the circumferential direction of the central axis of the rotary driver, and the storage tank shell to be welded can be welded along the circumferential direction. The storage tank shell always remains stationary, making the welding accurate.

[0007] Preferably, the guiding assembly includes a guiding substrate. The top of the guiding substrate is fixedly installed at the side of the bottom of the connecting flat plate by screws, and the guiding substrate is installed directly above the square frame. A bent extrusion plate is fixedly connected to the middle of the surface of the guiding substrate, and strip-shaped arc-shaped extension edges are fixedly connected to the sides of the surface of the bent extrusion plate. When the telescopic end of the hydraulic cylinder extends to push the connecting flat plate downward, as the connecting flat plate moves downward, the entire guiding assembly is driven to move downward. Then, the bottom end of the guiding substrate can be inserted into the interior of the square frame through the downward movement of the guiding substrate. By making the surface of the guiding substrate fit against the inner wall of the square frame, the guiding of the square frame to the guiding substrate enables the connecting flat plate to be supported by the guiding substrate, so that the connecting flat plate drives the rotary drive and the welding gun to move downward smoothly as a whole, reducing the influence of vibration.

[0008] Preferably, the guiding substrate is installed vertically. There are two strip-shaped arc-shaped extension edges, and the two strip-shaped arc-shaped extension edges are symmetrically installed along the bent extrusion plate.

[0009] Preferably, there are four circular limiting holes, and the four circular limiting holes are evenly distributed at the edge of the surface of the rotating workbench. The circular limiting holes, the arc-shaped elastic strips, and the clamping blocks are installed at the same height.

[0010] Preferably, the lifting assembly includes a connecting rotating shaft and a crescent-shaped lifting plate. The connecting rotating shaft is rotatably installed at the side of the bottom of the rotating workbench, and the crescent-shaped lifting plate is fixedly connected to the bottom end of the connecting rotating shaft. A torsion spring is fixedly installed between the top of the crescent-shaped lifting plate and the side of the bottom of the rotating workbench. A right-angled rod is fixedly connected to the side of the surface of the crescent-shaped lifting plate, and a cylinder is rotatably installed at the end of the surface of the right-angled rod away from the crescent-shaped lifting plate. By vertically placing the gas storage tank shell to be welded into the interior of the circular limiting hole and making the bottom of the gas storage tank shell contact the top of the crescent-shaped lifting plate, the gas storage tank shell can be supported and lifted by the crescent-shaped lifting plate, and thus the gas storage tank shell can be preliminarily limited.

[0011] Preferably, the crescent-shaped lifting plate is installed directly below the circular limiting hole. There are four crescent-shaped lifting plates, and the four crescent-shaped lifting plates are evenly installed at the bottom of the rotating workbench. The right-angled rod is installed vertically.

[0012] As the rotary workbench rotates, the gas tank shell in the circular limiting hole can be driven to move, and the gas tank shell can be loaded. When the gas tank shell moves to the bottom of the rotary driver, the rotation can be paused. At the same time, the arc-shaped elastic strip contacts the extended edge of the arc surface of the strip, and under the rotation of the rotary workbench, the arc-shaped elastic strip is squeezed by the bent extrusion plate. The elasticity of the arc-shaped elastic strip makes the surface of the clamping block fit with the outer cylindrical surface of the gas tank shell, so that the gas tank shell can be clamped and fixed, and it is not easy to deviate, which further helps to weld the gas tank shell.

[0013] Preferably, the torque spring is conical, and the connecting shaft passes through the center of the torque spring. The right-angled rod and the crescent lifting plate are installed at the same height. By rotating the workbench again, the welded gas tank shell can be removed, and the unwelded gas tank shell blank can be rotated for re-loading, which is conducive to mass production. The arc-shaped elastic strip is separated from the bent extrusion plate, and the bent extrusion plate drives the clamping block to move outward through its own elastic force, so that the gas tank shell can be loosened.

[0014] The top of the support frame is fixedly connected to the side of the body surface by screws, and the top of the support frame is fixedly connected to the guide plate, and the side of the guide plate surface is fixedly connected to the side of the bent baffle, and the side of the top of the bent baffle is fixedly connected to the arc-shaped toggle bar, and the inner side surface of the bent baffle is fixedly connected to an elastic buffer membrane, and the elastic buffer membrane is installed directly below the arc-shaped toggle bar, and the cylinder is in contact with the arc-shaped toggle bar. As the rotating workbench continues to rotate, the arc-shaped toggle bar applies a pushing force to the cylinder, and under the rotation connection of the connecting shaft, the crescent lifting plate rotates counterclockwise and moves out from directly below the circular limiting hole through the crescent lifting plate. The torque spring is elastically deformed by the torque force, and the gas tank shell in the circular limiting hole slides downward for automatic unloading. As the cylinder separates from the arc-shaped toggle bar, the driving force on the cylinder disappears, and under the elastic force of the torque spring, the connecting shaft drives the crescent lifting plate to rotate in the opposite direction to reset, which is convenient for supporting and lifting the new gas tank shell blank and helps mass production.

[0015] Preferably, the guide plate is installed at an angle, there are two bent baffles, and the two bent baffles are installed symmetrically along the central axis in the middle of the guide plate. The surface of the elastic buffer membrane is wavy. As the gas tank shell slides downward onto the elastic buffer membrane, the gas tank shell is connected to the material and flexible contact is achieved, which provides buffering protection for the gas tank shell and makes it less susceptible to damage. The guide plate is installed at an angle so that the gas tank shell slides downward.

[0016] The present invention provides a welding device for the production of a housing for an air compressor. It has the following beneficial effects: For the welding device for the production of a housing for an air compressor, by the telescopic end of the hydraulic cylinder extending and contracting, it can drive the connecting flat plate to move downward and upward. And under the connection of the rotary drive, the welding gun is driven to move, so that the height of the welding gun can be adjusted, making the welding end of the welding gun at an appropriate height with the housing of the air compressor storage tank to be welded, thus helping to weld the storage tank properly.

[0017] Second, for the welding device for the production of a housing for an air compressor, by the downward movement of the guiding base plate, the bottom end of the guiding base plate is inserted into the interior of the square frame. By the surface of the guiding base plate being in contact with the inner wall of the square frame, through the guiding of the square frame to the guiding base plate, the connecting flat plate is supported by the guiding base plate, so that the connecting flat plate drives the rotary drive and the welding gun as a whole to move downward stably, reducing the influence of vibration.

[0018] Third, for the welding device for the production of a housing for an air compressor, the telescopic end of the electric telescopic rod can apply a pulling force to the welding gun, and combined with the hinged connection between the rotating end of the rotary drive at the top of the welding gun, the welding gun can be rotated to adjust the angle. And by the extension of the telescopic end of the electric telescopic rod, the welding gun can be pushed, so that the welding gun rotates outward, and the angle can be adjusted by the rotation of the welding gun.

[0019] Fourth, for the welding device for the production of a housing for an air compressor, by the rotation of the rotating end at the bottom of the rotary drive, the welding gun can be driven to rotate together, making the welding gun rotate along the circumferential direction of the central axis of the rotary drive, so that the housing of the storage tank to be welded can be welded along the circumferential direction. The housing of the storage tank remains stationary all the time, making the welding accurate.

[0020] Fifth, for the welding device for the production of a housing for an air compressor, by vertically placing the housing of the storage tank to be welded into the interior of the circular limiting hole, and with the bottom of the housing of the storage tank in contact with the top of the crescent-shaped supporting plate, the housing of the storage tank can be supported and lifted by the crescent-shaped supporting plate, and the housing of the storage tank can be preliminarily limited.

[0021] Sixth, for the welding device for the production of a housing for an air compressor, when the housing of the storage tank moves to directly below the rotary drive, the rotation can be paused. At the same time, the arc-shaped elastic strip contacts the strip-shaped arc surface extension edge, and under the rotation of the rotating workbench, the arc-shaped elastic strip is squeezed by the bending pressing plate. Through the elasticity of the arc-shaped elastic strip, the surface of the clamping block can be attached to the outer circular surface of the housing of the storage tank, so that the housing of the storage tank can be clamped and fixed, and it is not easy to shift.

[0022] 7. The welding equipment for the production of the shell of the air compressor can rotate the workbench again to remove the welded gas tank shell and rotate the unwelded gas tank shell blank for re-loading, which is conducive to mass production. The arc-shaped elastic strip is separated from the bent extrusion plate, and the bent extrusion plate drives the clamping block to move outward through its own elastic force, so that the gas tank shell can be loosened.

[0023] 8. The welding equipment used in the production of the air compressor shell uses an arc-shaped toggle bar to apply a driving force to the cylinder, causing the crescent lifting plate to rotate counterclockwise and move out from directly below the circular limit hole. The torque spring is elastically deformed by the torque force, causing the air tank shell in the circular limit hole to slide downward for automatic unloading.

[0024] 9. The welding equipment used in the production of the air compressor shell is such that as the cylinder separates from the arc-shaped toggle bar, the driving force on the cylinder disappears, and under the elastic force of the torque spring, the connecting shaft drives the crescent lifting plate to rotate in the opposite direction to reset it, making it easier to support and lift the new gas tank shell blank, which is helpful for mass production.

[0025] 10. The welding equipment used in the production of the shell of the air compressor is used to connect the gas tank shell and achieve flexible contact as the gas tank shell slides down onto the elastic buffer membrane, providing buffering protection for the gas tank shell, making it less susceptible to damage. The guide plate is installed at an angle to allow the gas tank shell to slide downward. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The first embodiment, as Figures 1 to 4 As shown, the present invention provides a technical solution: A welding device for producing a shell for processing an air compressor, comprising: The machine body 1, and the frame 2 fixedly installed on the side of the surface of the machine body 1, the side of the top of the machine body 1 is fixedly connected with a square frame 3, and the middle of the top of the machine body 1 is installed with a feeding mechanism 4; Processing mechanism 5, which is used to perform welding processing on the air storage tank on the air compressor, and is installed in the middle of the top of the frame 2; Among them, the processing mechanism 5 includes a hydraulic cylinder 51 and a connecting plate 52. The hydraulic cylinder 51 is installed in the middle of the top of the frame 2, and the connecting plate 52 is fixedly connected to the telescopic end of the hydraulic cylinder 51. A rotary drive 53 is fixedly installed in the middle of the bottom of the connecting plate 52. A welding gun 54 is hinged at the edge of the rotating end of the rotary drive 53, and an electric telescopic rod 55 is hinged at the side of the bottom of the rotating end of the rotary drive 53. A guide assembly 56 is installed at the side of the bottom of the connecting plate 52. The staff starts the hydraulic cylinder 51 to work, and uses the telescopic end of the hydraulic cylinder 51 to extend and contract, which can drive the connecting plate 52 to move downward and upward, and under the connection of the rotary drive 53, the welding gun 54 is driven to move, so that the height of the welding gun 54 can be adjusted so that the welding end of the welding gun 54 is at a suitable height with the air compressor tank shell to be welded.

[0030] The telescopic end of the electric telescopic rod 55 is hinged to the surface of the electric telescopic rod 55. Both the electric telescopic rod 55 and the electric telescopic rod 55 are inclined. When the staff turns on the electric telescopic rod 55 to contract, a pulling force can be applied to the welding torch 54 through the telescopic end of the electric telescopic rod 55. Combined with the hinge between the top end of the welding torch 54 and the rotating end of the rotary driver 53, the welding torch 54 can be rotated to adjust the angle. And by the elongation of the telescopic end of the electric telescopic rod 55, the welding torch 54 can be pushed, so that the welding torch 54 rotates outward, and the angle can be adjusted by the rotation of the welding torch 54.

[0031] By starting the rotary driver 53 to work and using the rotation of the rotating end at the bottom of the rotary driver 53, the welding torch 54 can be driven to rotate together, so that the welding torch 54 rotates along the circumferential direction of the central axis of the rotary driver 53, and welding is carried out along the circumferential direction on the gas storage tank shell to be welded.

[0032] The guiding component 56 includes a guiding base plate 561. The top of the guiding base plate 561 is fixedly installed at the side of the bottom of the connecting flat plate 52 by screws, and the guiding base plate 561 is installed directly above the square frame 3. A bent extrusion plate 562 is fixedly connected to the middle of the surface of the guiding base plate 561. Strip-shaped arc-shaped extension edges 563 are fixedly connected to the sides of the surface of the bent extrusion plate 562. When the telescopic end of the hydraulic cylinder 51 elongates to push the connecting flat plate 52 downward, as the connecting flat plate 52 moves downward, the whole guiding component 56 is driven to move downward. Then, through the downward movement of the guiding base plate 561, the bottom end of the guiding base plate 561 can be inserted into the inside of the square frame 3. By making the surface of the guiding base plate 561 fit with the inner wall of the square frame 3 and guiding the guiding base plate 561 through the square frame 3, the connecting flat plate 52 is supported by the guiding base plate 561, so that the connecting flat plate 52 drives the rotary driver 53 and the welding torch 54 to move downward smoothly as a whole.

[0033] The guiding base plate 561 is installed vertically. There are two strip-shaped arc-shaped extension edges 563, and the two strip-shaped arc-shaped extension edges 563 are symmetrically installed along the bent extrusion plate 562.

[0034] The second embodiment, on the basis of the first embodiment, please refer to Figures 1 to 6 as shown: The feeding mechanism 4 includes a rotating workbench 41 and a circular limiting hole 42. The rotating workbench 41 is rotatably installed at the middle of the top of the machine body 1. The circular limiting hole 42 is opened at the edge of the surface of the rotating workbench 41. An arc-shaped elastic strip 43 is fixedly connected to the position of the circular limiting hole 42 at the edge of the rotating workbench 41. A clamping block 44 is fixedly connected to the inner side of the arc-shaped elastic strip 43. A lifting component 45 is installed at the side of the bottom of the rotating workbench 41.

[0035] There are four circular limiting holes 42, and the four circular limiting holes 42 are evenly distributed at the edge of the surface of the rotating workbench 41. The circular limiting holes 42, the arc-shaped elastic strip 43 and the clamping block 44 are installed at the same height.

[0036] The lifting assembly 45 includes a connecting rotating shaft 451 and a crescent lifting plate 452. The connecting rotating shaft 451 is rotatably installed at the side of the bottom of the rotating workbench 41. The crescent lifting plate 452 is fixedly connected to the bottom end of the connecting rotating shaft 451. A torsion spring 453 is fixedly installed between the top of the crescent lifting plate 452 and the side of the bottom of the rotating workbench 41. A right-angled rod 454 is fixedly connected to the side of the surface of the crescent lifting plate 452. A cylinder 455 is rotatably installed on the surface of the right-angled rod 454 and away from the crescent lifting plate 452. By vertically placing the gas storage tank shell to be welded into the inside of the circular limiting hole 42 and making the bottom of the gas storage tank shell contact with the top of the crescent lifting plate 452, the gas storage tank shell can be supported and lifted by the crescent lifting plate 452, and the gas storage tank shell can be preliminarily positioned.

[0037] The crescent lifting plate 452 is installed directly below the circular limiting hole 42. There are four crescent lifting plates 452, and the four crescent lifting plates 452 are evenly installed at the bottom of the rotating workbench 41. The right-angled rod 454 is vertically installed.

[0038] As the rotating workbench 41 rotates, the gas storage tank shell in the circular limiting hole 42 can be driven to move, so that the gas storage tank shell can be loaded. When the gas storage tank shell moves to directly below the rotary actuator 53, the rotation can be paused. At the same time, the arc-shaped elastic strip 43 contacts the strip-shaped arc surface extension edge 563, and under the rotation of the rotating workbench 41, the arc-shaped elastic strip 43 is squeezed by the bending pressing plate 562. Through the elasticity of the arc-shaped elastic strip 43, the surface of the clamping block 44 can be attached to the outer circular surface of the gas storage tank shell, and the gas storage tank shell can be clamped and fixed.

[0039] The torsion spring 453 is conical, and the connecting rotating shaft 451 passes through the center of the torsion spring 453. The right-angled rod 454 and the crescent lifting plate 452 are installed at the same height. After the gas storage tank shell is welded, the rotating workbench 41 can be rotated again. The welded gas storage tank shell can be removed, and the blank of the gas storage tank shell that has not been welded can be rotated for reloading, which helps with batch production. At the same time, the arc-shaped elastic strip 43 is separated from the bending pressing plate 562, and the bending pressing plate 562 drives the clamping block 44 to move outward by its own elastic force to release the gas storage tank shell.

[0040] The third embodiment, on the basis of the first and second embodiments, please refer to Figures 1 to 8 as shown in A material receiving mechanism 6 is installed on the side of the surface of the body 1. The material receiving mechanism 6 includes a support frame 61, which is fixedly connected to the side of the surface of the body 1 by screws. The top of the support frame 61 is fixedly connected to a material guide plate 62, and the side of the surface of the guide plate 62 is fixedly connected to a bent baffle 63. The side of the top of the bent baffle 63 is fixedly connected to an arc-shaped toggle strip 64. The inner side of the bent baffle 63 is fixedly connected to an elastic buffer membrane 65, and the elastic buffer membrane 65 is installed on the arc-shaped toggle strip 64. Directly below the circular stop hole 42, the cylinder 455 is in contact with the arc-shaped toggle bar 64. As the rotating workbench 41 continues to rotate, the arc-shaped toggle bar 64 applies a pushing force to the cylinder 455. Under the rotation connection of the connecting shaft 451, the crescent lifting plate 452 rotates counterclockwise. The crescent lifting plate 452 moves out from directly below the circular limit hole 42. The torque spring 453 is elastically deformed by the torque force, and the gas tank shell in the circular limit hole 42 slides downward to perform automatic unloading. As the cylinder 455 separates from the arc-shaped toggle bar 64, the driving force on the cylinder 455 disappears, and under the elastic force of the torque spring 453, the connecting shaft 451 drives the crescent lifting plate 452 to rotate in the opposite direction to reset, so as to support and lift the new gas tank shell blank.

[0041] The guide plate 62 is installed at an angle, and there are two bent baffles 63, and the two bent baffles 63 are installed symmetrically along the central axis in the middle of the guide plate 62. The surface of the elastic buffer membrane 65 is wavy. As the gas tank shell slides down onto the elastic buffer membrane 65, the gas tank shell is connected and flexible contact is achieved, which provides buffering protection for the gas tank shell and is not easily damaged. The guide plate 62 is installed at an angle, so that the gas tank shell slides down.

[0042] When in use, first vertically place the gas tank shell to be welded into the circular limiting hole 42, and make the bottom of the gas tank shell contact the top of the crescent lifting plate 452, so that the gas tank shell can be supported and lifted by the crescent lifting plate 452, and the gas tank shell can be initially limited; At this time, the operator starts the hydraulic cylinder 51 and uses the telescopic end of the hydraulic cylinder 51 to extend, which can drive the connecting plate 52 to move downward. Under the connection of the rotary driver 53, the welding gun 54 is driven to move and the height of the welding gun 54 is adjusted so that the welding end of the welding gun 54 is at a suitable height with the air compressor tank shell to be welded. When the telescopic end of the hydraulic cylinder 51 extends to push the connecting flat plate 52 downward, as the connecting flat plate 52 moves downward, the entire guiding assembly 56 is driven to move downward. Then, through the downward movement of the guiding substrate 561, the bottom end of the guiding substrate 561 is inserted into the interior of the square frame 3. By making the surface of the guiding substrate 561 fit against the inner wall of the square frame 3, and through the guiding of the square frame 3 on the guiding substrate 561, the connecting flat plate 52 is supported by the guiding substrate 561, so that the connecting flat plate 52 drives the rotary drive 53 and the welding gun 54 to move downward smoothly as a whole; As the rotating workbench 41 rotates, the gas storage tank shell within the circular limiting hole 42 can be driven to move, enabling the feeding of the gas storage tank shell. When the gas storage tank shell moves to directly below the rotary drive 53, the rotation can be paused. At the same time, the arc-shaped elastic strip 43 contacts the strip-shaped arc surface extension edge 563, and under the rotation of the rotating workbench 41, the arc-shaped elastic strip 43 is squeezed by the bending extrusion plate 562. Through the elasticity of the arc-shaped elastic strip 43, the surface of the clamping block 44 fits against the outer circular surface of the gas storage tank shell, thus clamping and fixing the gas storage tank shell; Moreover, when the staff activates the electric telescopic rod 55 to contract, a pulling force can be exerted on the welding gun 54 through the telescopic end of the electric telescopic rod 55. Considering the hinge connection between the top end of the welding gun 54 and the rotating end of the rotary drive 53, the welding gun 54 can be rotated to adjust the angle. And through the extension of the telescopic end of the electric telescopic rod 55, the welding gun 54 can be pushed, so that the welding gun 54 rotates outward, and the angle can be adjusted by the rotation of the welding gun 54; By starting the rotary drive 53 to operate, using the rotation of the rotating end at the bottom of the rotary drive 53, the welding gun 54 can be driven to rotate together, enabling the welding gun 54 to rotate along the circumferential direction of the central axis of the rotary drive 53 to perform circumferential welding on the gas storage tank shell to be welded; After the welding of the gas storage tank shell is completed, the rotating workbench 41 can be rotated again to remove the welded gas storage tank shell and rotate the blank of the gas storage tank shell that has not been welded for re-feeding, which is conducive to mass production. At this time, the arc-shaped elastic strip 43 is separated from the bending extrusion plate 562, and the bending extrusion plate 562 drives the clamping block 44 to move outward by its own elastic force to release the gas storage tank shell; Furthermore, the cylinder 455 contacts the arc-shaped toggle bar 64, and as the rotating workbench 41 continues to rotate, the arc-shaped toggle bar 64 applies a pushing force to the cylinder 455. Under the rotation connection of the connecting shaft 451, the crescent lifting plate 452 rotates counterclockwise, and the crescent lifting plate 452 moves out from directly below the circular limiting hole 42. The torque spring 453 is elastically deformed by the torque force, and the gas tank shell in the circular limiting hole 42 slides downward, thereby performing automatic unloading. As the cylinder 455 separates from the arc-shaped toggle bar 64, the driving force on the cylinder 455 disappears, and under the elastic force of the torque spring 453, the connecting shaft 451 drives the crescent lifting plate 452 to rotate in the opposite direction to reset, so as to support and lift the new gas tank shell blank. As the gas tank shell slides down onto the elastic buffer membrane 65, the gas tank shell is connected to the material and flexible contact is achieved, which provides buffering protection for the gas tank shell and makes it less susceptible to damage. The guide plate 62 is installed obliquely to allow the gas tank shell to slide down.
