Description

Technical Field

[0001] The utility model relates to a high-precision black metal spiral tube welding device, belonging to the technical field of welding devices. Background Technique

[0002] Welding, also known as fusion welding, is a manufacturing process and technology for joining metals or other thermoplastic materials such as plastics by means of heating, high temperature or high pressure. There are many energy sources for modern welding, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasonic waves. In addition to being used in factories, welding can also be carried out in various environments, such as in the wild, underwater, and in space. No matter where it is, welding may pose risks to operators. Therefore, appropriate protective measures must be taken during welding. The injuries that welding may cause to the human body include burns, electric shock, vision damage, inhalation of toxic gases, excessive ultraviolet radiation, etc.

Moreover, the existing device cannot fix and clamp spiral tubes of different sizes during the welding process, which may cause the device to roll easily during operation, thus affecting the welding efficiency of the device.

[0005] Therefore, a high-precision black metal spiral tube welding device is proposed. Utility Model Content

[0019] Second, by setting a limiting groove in the present utility model, it can limit the movement of the screw block to avoid deviation during the movement of the screw block, thus affecting the fixing work of the spiral tube. By setting a notch, since the size of its inner cavity is interconnected with the size inside the driven synchronous shaft, it is convenient to place the spiral tube through the inside of the driven synchronous shaft and the inner cavity of the notch and into the inside of the clamping plate, improving the convenience of feeding and discharging the spiral tube. By setting the electric telescopic rod and the supporting platform, it can conveniently support the spiral tube during welding, improving the stability of the spiral tube during welding. By setting a protective pad, it can avoid the direct contact between the supporting platform and the spiral tube when driving the spiral tube to rotate, thus preventing the spiral tube from being worn. By setting anchor bolts, it can play a role in stabilizing the overall equipment and avoid the situation that the overall equipment topples due to accidental collision.

[0029] The following will describe the embodiments of the present utility model in detail with reference to the drawings.

[0030] Embodiment 1

[0031] As Figures 1-5As shown in the figure, an embodiment of the present utility model provides a high-precision black metal spiral pipe welding device, which includes a bottom plate 1. Vertical plates 4 are fixedly installed on both the left and right sides of the top of the bottom plate 1. A support frame 5 is fixedly installed on the top of the bottom plate 1. A gas welding box 7 is arranged at the bottom of the support frame 5. A gas welding nozzle 8 is fixedly installed at the bottom of the gas welding box 7. A gas storage box 9 is fixedly installed at the top of the support frame 5. An intake hose 10 communicates with the front side of the gas storage box 9. One end of the intake hose 10 away from the gas storage box 9 communicates with the front side of the gas welding box 7;

[0032] A rotating mechanism 2 is arranged on the top of the bottom plate 1. The rotating mechanism 2 includes a bidirectional motor 201. Output ends on both the left and right sides of the bidirectional motor 201 are fixedly connected with smooth rods 202. Active synchronous shafts 203 are fixedly installed on the outer sides of the two smooth rods 202. Driven synchronous shafts 204 are movably connected to the outer sides of the two vertical plates 4. Synchronous drive belts 205 are movably connected to the surfaces of the two driven synchronous shafts 204 and the two active synchronous shafts 203. Inner sides of the two driven synchronous shafts 204 are fixedly connected with turntables 206.

[0033] By setting the rotating mechanism 2, through the output of the bidirectional motor 201, at this time the smooth rod 202 drives the active synchronous shaft 203 to rotate, and through the mutual cooperation of the active synchronous shaft 203 and the synchronous drive belt 205, the driven synchronous shaft 204 drives the turntable 206 to rotate. As the turntable 206 rotates, the clamping mechanism 3 inside the turntable 206 and the spiral pipe will rotate synchronously, thus saving the steps for the operator to adjust the welding torch to rotate around the spiral pipe for welding, improving the welding convenience, and facilitating the operator to use.

[0034] Embodiment 2

[0035] Such as Figures 1-3As shown, in one embodiment, clamping mechanisms 3 are provided on the inner sides of two turntables 206. The clamping mechanism 3 includes a mounting frame 301, a servo motor 302, and a bidirectional screw 306. The two mounting frames 301 are fixedly installed on the inner sides of the turntables 206. The two servo motors 302 are fixedly installed on the rear sides of the two mounting frames 301. The four bidirectional screws 306 are arranged on the inner sides of the two mounting frames 301. The upper and lower sides of the surfaces of the four bidirectional screws 306 are threadedly connected with screw blocks 307. Clamping plates 308 are fixedly installed on the inner sides of the eight screw blocks 307. The output ends of the two servo motors 302 are fixedly connected with connecting rods 303. Active bevel gears 304 are fixedly installed on the surfaces of the two connecting rods 303. The tops of the four bidirectional screws 306 are fixedly connected with driven bevel gears 305. The surfaces of the four active bevel gears 304 are meshed with the surfaces of the four driven bevel gears 305. Limiting grooves 309 are provided on the front and rear sides of the inner sides of the two mounting frames 301. The outer sides of the eight screw blocks 307 are slidably connected to the inner cavities of the four limiting grooves 309. Notches 310 are provided on the surfaces of the two mounting frames 301 and the two turntables 206. The inner cavities of the notches 310 communicate with the inner sides of the driven synchronous shafts 204. Electric telescopic rods 11 are fixedly installed on the left and right sides of the top of the bottom plate 1. The tops of the four electric telescopic rods 11 are fixedly installed with separating platforms 12. Protective pads 13 are adhered to the inner sides of the two separating platforms 12, and the material of the protective pads 13 is sponge. A cylinder 6 is fixedly installed on the top of the support frame 5. The bottom of the cylinder 6 is fixedly connected to the top of the gas welding box 7. Anchor bolts 14 are threadedly connected to the four sides of the top of the bottom plate 1. The bottoms of the four anchor bolts 14 are threadedly connected to the ground.

[0036] By setting the clamping mechanism 3, driven by the output of the servo motor 302, the connecting rod 303 drives the active bevel gear 304 to rotate. At this time, the active bevel gear 304 cooperates with the driven bevel gear 305, and the bidirectional screw 306 rotates synchronously, driving the screw block 307 to move inward. At this time, the clamping plate 308 moves inward synchronously to clamp spiral tubes of different sizes. By clamping the spiral tube, it effectively prevents the spiral tube from rolling during the welding process, thus affecting the normal welding steps and delaying the normal welding efficiency. By setting the limit groove 309, the movement of the screw block 307 can be limited to prevent the screw block 307 from shifting during movement, thus affecting the fixing of the spiral tube. By setting the notch 310, since the size of its inner cavity is connected to the size of the inner side of the driven synchronous shaft 204, it is convenient to place the spiral tube through the inner side of the driven synchronous shaft 204 and the inner cavity of the notch 310 and place it inside the clamping plate 308, improving the convenience of feeding and discharging the spiral tube. By setting the electric telescopic rod 11 and the lifting platform 12, it is convenient to support the spiral tube during welding, improving the stability of the spiral tube during welding. By setting the protective pad 13, it can prevent the lifting platform 12 from directly contacting the spiral tube when driving the spiral tube to rotate, thus avoiding the situation of abrasion of the spiral tube. By setting the anchor bolts 14, it can stabilize the entire equipment and prevent the entire equipment from tipping over due to accidental collision.

[0037] When the utility model is working: First, place the spiral tube inside the clamping plate 308 through the inner cavity of the driven synchronous shaft 204 and the notch 310. Subsequently, driven by the output of the servo motor 302, the connecting rod 303 drives the active bevel gear 304 to rotate. As the active bevel gear 304 rotates, the driven bevel gear 305 rotates synchronously, causing the bidirectional screw 306 to rotate. At this time, the screw block 307 drives the clamping plate 308 to move inward to complete the fixing of the spiral tube. Subsequently, the cylinder 6 drives the gas welding box 7 and the gas welding nozzle 8 to move downward to start welding the spiral tube. At this time, driven by the output of the bidirectional motor 201, the smooth rod 202 drives the active synchronous shaft 203 to rotate, and through the cooperation of the active synchronous shaft 203 and the synchronous transmission belt 205, the driven synchronous shaft 204 drives the turntable 206 to rotate synchronously. Through the rotation of the turntable 206, the clamping mechanism 3 drives the spiral tube to rotate synchronously, thus completing the rotation of the spiral tube.

[0038] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily conceive of various changes or substitutions thereof, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims described above.
