Description

Technical Field

[0001] This invention relates to the field of air compressor devices, and more particularly to a welding device for an air compressor storage tank. Background Technology

[0002] An air compressor is a device used to compress gas. Air compressors are similar in construction to water pumps. Most air compressors are reciprocating piston type, rotary vane or rotary screw type. The air tank is used to store the gas compressed by the air compressor (air pump).

[0003] Air compressor tanks are generally welded together from two end caps and a cylinder. Patent application CN202421751909.6 discloses an auxiliary tooling for welding end caps and cylinders in air compressor tank processing. It includes a base plate: a vertical plate 1 is fixedly connected to the left side of the top of the base plate; a rotatable rotating rod is installed through the top of one side of the vertical plate 1; a sleeve 1 is fixedly connected to the right end of the rotating rod; a vertical plate 2 is fixedly connected to the right side of the top of the base plate; a cylinder is fixedly installed on the top of the right side of the vertical plate 2; the output end of the cylinder extends through to the left side of the vertical plate 2 and a connecting block is fixedly installed; a sleeve 2 is rotatably connected to the left side of the connecting block; sleeve 1 and sleeve 2 are symmetrically arranged; two end cap bodies and a cylinder body are arranged between sleeve 1 and sleeve 2; an adjustable support assembly is arranged on the rear side of the top of the base plate; and a movable welding torch is arranged on the adjustable support assembly. The motor and pulley work together to drive the rotating rod and the first sleeve to rotate, which in turn drives the second sleeve to rotate through the tank body composed of the cylinder body and the end cap body. This makes the cylinder body and the end cap body rotate slowly and uniformly. Then the welding gun is opened to realize the welding work at the connection between the cylinder body and the end cap body. However, this method of welding two end caps in sequence with a single welding gun results in low welding efficiency.

[0004] This invention was proposed in response to the shortcomings of existing technologies. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a welding device for air compressor storage tanks.

[0006] This invention can be achieved through the following technical solutions:

[0007] This invention discloses a welding device for an air compressor storage tank, comprising a base plate, on which support shafts are symmetrically fixed on both sides. Each support shaft is equipped with a support roller that is rolletly connected to the support shaft. The base plate also includes a feeding screw and a support rod. The feeding screw is driven to rotate by a feeding motor. Feeding devices are symmetrically arranged on both sides of the feeding screw. Each feeding device includes a fixed plate, on which a threaded tube and a support tube are fixed at the bottom. The support rod passes through the support tube at a corresponding position and is slidably connected to the support tube. The feeding screw passes through the threaded tube at a corresponding position and is threadedly connected to the threaded tube. Each fixed plate is equipped with a rotating shaft rotatably connected to the fixed plate, driven to rotate by a rotating motor. Each rotating shaft is equipped with a support roller that is rotatably connected to the fixed plate. A turntable is fixed, and a support plate is fixed to the bottom of the turntable. A positioning block is fixed to the top of the turntable, and a positioning plate is set below the positioning block. A screw is fixed to the positioning plate, and the screw passes through the positioning block and is slidably connected to the positioning block. A nut is also set on the positioning block and is rotatably connected to the positioning block. The screw passes through the nut and is threadedly connected to the nut. A top plate is fixed above the bottom plate, and multiple hydraulic cylinders are fixed on the top plate. A slide is set below the top plate, and the piston rod ends of the hydraulic cylinders are fixed to the slide. A welding screw is also set on the slide, and the welding screw is driven to rotate by a welding motor. Slider blocks are symmetrically arranged on both sides of the welding screw and are threadedly connected to the welding screw. A welding gun is fixed on each slider.

[0008] Preferably, the slide table is further fixed with multiple slide rods, which pass through the slider and are slidably connected to the slider.

[0009] Preferably, a pulley is fixed on the rotating shaft, and a pulley is also fixed at the output end of the rotary motor. The two pulleys are connected by a synchronous belt.

[0010] Preferably, a positioning rod is also fixed to the positioning plate, the positioning rod passing through the positioning block and slidably connected to the positioning block. The positioning rod can prevent the positioning plate from rotating.

[0011] Preferably, multiple fixing blocks are also provided below the slide table. Limiting shafts are symmetrically fixed on both sides below each fixing block. Each limiting shaft is equipped with a limiting wheel rotatably connected to the limiting shaft. Multiple limiting rods are also fixed to each fixing block, passing through the slide table and slidably connected to it. A limiting block is fixed to the top of each limiting rod. Multiple springs are also fixed between the slide table and the fixing blocks. When the slide table descends, the limiting wheels fix the cylinder from the top, preventing vibration and displacement of the cylinder during welding that could affect the welding quality.

[0012] Compared with existing technologies, the present invention has the following advantages:

[0013] This device welds gas storage tanks simultaneously using two welding torches, greatly improving the production efficiency of gas storage tanks. Furthermore, the welding motor drives the welding screw to rotate, and since the threads on the two sliders are in opposite directions, the distance between the two welding torches can be adjusted to meet the welding needs of gas storage tanks of different lengths.

[0019] Example 1:

[0020] like Figures 1 to 2As shown, this embodiment discloses a welding device for an air compressor storage tank, comprising a base plate 1, with support shafts 30 symmetrically fixed on both sides of the upper part of the base plate 1. Each support shaft 30 is provided with a support roller 31 that is rollably connected to the support shaft 30. The base plate 1 is also provided with a feeding screw 3 and a support rod 2. The feeding screw 3 is driven to rotate by a feeding motor 4. Feeding devices are symmetrically arranged on both sides of the feeding screw 3. The feeding device includes a fixed plate 5. A threaded tube 6 and a support tube 7 are fixed at the bottom of the fixed plate 5. The support rod 2 passes through the support tube 7 at the corresponding position and is slidably connected to the support tube 7. The feeding screw 3 passes through the threaded tube 6 at the corresponding position and is threadedly connected to the threaded tube 6. Each fixed plate 5 is provided with a rotating shaft 8 that is rotatably connected to the fixed plate 5. The rotating shaft 8 is driven to rotate by a rotating motor 34. A turntable 9 is fixed on each rotating shaft 8. The bottom of the turntable 9 is... A support plate 10 is also fixed, and a positioning block 11 is fixed on the top of the turntable 9. A positioning plate 12 is set below the positioning block 11, and a screw 14 is fixed on the positioning plate 12. The screw 14 passes through the positioning block 11 and is slidably connected to the positioning block 11. A nut 13 is also set on the positioning block 11 and is rotatably connected to the positioning block 11. The screw 14 passes through the nut 13 and is threadedly connected to the nut 13. A top plate 16 is also fixed above the bottom plate 1. Multiple hydraulic cylinders 17 are fixed on the top plate 16. A slide table 18 is also set below the top plate 16. The piston rod ends of the hydraulic cylinders 17 are all fixed to the slide table 18. A welding screw 19 is also set on the slide table 18. The welding screw 19 is driven to rotate by the welding motor 21. Slider blocks 22 are symmetrically arranged on both sides of the welding screw 19 and are threadedly connected to the welding screw 19. A welding gun 23 is fixed on each of the sliders 22.The cylindrical body is placed between two support rollers 31, which support the body. Two end caps are placed on corresponding support plates 10. The corresponding nuts 13 are rotated. Since the nuts 13 are threadedly connected to the screw 14, the screw 14 moves as the nuts 13 rotate, causing the positioning plate 12 to move closer to the end caps. The positioning plate 12 presses against the end caps, fixing them to the support plates 10. After the end caps are fixed, the feeding motor 4 drives the feeding screw 3 to rotate. Since the feeding screw 3 is threadedly connected to the corresponding threaded pipe 6, and the threads on the two threaded pipes 6 are in opposite directions, the threaded pipes 6 move closer to each other as the feeding screw 3 rotates, causing the end caps to move with the threaded pipes 6. After both end caps contact the cylinder, the feeding motor 4 stops, the hydraulic cylinder 17 starts, the piston rod on the hydraulic cylinder 17 extends, and the welding torch 23 moves. After the welding torch 23 contacts the cylinder and the end caps, welding is performed. The welding gun 23 welds at the contact point. After spot welding with the welding gun 23, the end cap is fixed to the cylinder. The end cap is driven to rotate by the rotary motor 34, which in turn drives the cylinder to rotate. While the cylinder rotates, the welding gun 23 welds at the contact point between the end cap and the cylinder. After the cylinder rotates one revolution, the welding gun 23 stops working, the hydraulic cylinder 17 starts, the piston rod on the hydraulic cylinder 17 shortens, the welding gun 23 separates from the cylinder, and the nut 13 rotates in the opposite direction again, the positioning plate 12 rises, and the feeding motor 4 drives the feeding screw 3 to rotate in the opposite direction, removing the welded gas storage tank. This device welds the gas storage tank simultaneously with two welding guns 23, which greatly improves the production efficiency of the gas storage tank. The welding motor 21 drives the welding screw 19 to rotate. Since the threads on the two sliders 22 are in opposite directions, the distance between the two welding guns 23 can be adjusted to meet the welding requirements of gas storage tanks of different lengths.

[0021] The slide table 18 is also fixed with multiple slide rods 20, which pass through the slider 22 and are slidably connected to the slider 22.

[0022] Among them, a pulley 32 is fixed on the rotating shaft 8, and a pulley 32 is also fixed at the output end of the rotating motor 34. The two pulleys 32 are connected by a synchronous belt 33.

Limiting shafts 28 are symmetrically fixed on both sides below the fixing blocks 24. Each limiting shaft 28 is equipped with a limiting wheel 29 rotatably connected to it. Multiple limiting rods 25 are also fixed to the fixing blocks 24, passing through the slide table 18 and slidably connected to it. A limiting block 27 is fixed to the top of each limiting rod 25. Multiple springs 26 are also fixed between the slide table 18 and the fixing blocks 24. When the slide table 18 descends, the cylinder is fixed from the top by the limiting wheels 29, preventing vibration and displacement of the cylinder during welding that could affect the welding quality.
