[0023] refer to Figures 1 to 6 The present invention provides a gas shielded welding machine, comprising a welding machine body 100, an integrated pipeline 200, a welding gun 300, and a pipeline reeling mechanism 400. The integrated pipeline 200 is connected between the welding machine body 100 and the welding gun 300. The integrated pipeline 200 includes a sheath 201 and various wiring harnesses integrated within the sheath 201, such as an electrical wiring harness 202, a shielding gas delivery harness 203, and a coolant delivery harness 204. The pipeline reeling mechanism 400 is provided in the welding machine and is used to reel the integrated pipeline 200.

[0024] The gas shielded welder of this embodiment has multiple wire harnesses integrated into its integrated pipeline 200, and the integrated pipeline 200 can be reeled by a pipeline reeling mechanism 400. Compared to conventional designs, the wire harnesses of the gas shielded welder are integrated, which allows the wire harnesses to be reeled uniformly. Moreover, during the reeling process, the wire harnesses do not become entangled or knotted with each other, which can reduce the difficulty of reeling the wire harnesses and the time and energy required. At the same time, the integrated arrangement of the wire harnesses can increase the overall strength and toughness of the wire harnesses, helping to reduce the risk of rupture of the wire harness outer skin and damage to the internal wires. In addition, the gas shielded welder also uses a pipeline reeling mechanism 400 to reel the wire harnesses, which makes the reeled wire harnesses relatively neat, helping to reduce the storage space requirements of the gas shielded welder.

[0025] Optionally, in this embodiment, the welder body 100 includes a main unit 110, which is connected to the welding gun 300 via an electrical wiring harness to conduct current from the welder to the welding gun 300, enabling the welding wire to conduct electricity and melt. Of course, the electrical wiring harness 202 may also include control lines, such as motor control lines, solenoid valve control lines, and gun switch control lines, for controlling various functions of the welder. In a specific configuration, the electrical wiring harness 202 may be integrated within the sheath 201.

[0026] Optionally, in this embodiment, the welding machine body 100 includes a gas cylinder 120, which is connected to the welding torch 300 via a shielding gas delivery harness to deliver shielding gas to the welding torch 300, thereby providing shielding gas to the welding area and preventing metal oxidation during welding. In a specific configuration, the shielding gas delivery harness 203 can be integrated into the sheath 201.

[0027] Optionally, in this embodiment, the welding machine body 100 includes a cooling box 130, which is connected to the welding gun 300 via a coolant delivery harness. This allows coolant to circulate between the welding gun 300 and the cooling box 130, thereby cooling the welding gun 300 and preventing the welding gun 300 from overheating. In a specific configuration, the coolant delivery harness 204 can be integrated into the sheath 201.

[0028] Optionally, in this embodiment, the welding body includes a storage box 140 , and the storage box 140 is used to store the welding gun 300 .

[0029] Optionally, in this embodiment, the welding machine body 100 includes a fixed base 150, and the host 110, gas cylinder 120, cooling box 130 and storage box 140 are all arranged on the fixed base 150 to achieve integration. Further, in order to facilitate movement, the bottom of the fixed base 150 can be provided with rollers 151.

[0030] Optionally, in this embodiment, the wiring harness of the integrated pipeline 200 may include at least two of the electrical wiring harness 202, the shielding gas delivery wiring harness 203, and the coolant delivery wiring harness 204. Figure 2 As shown, in this embodiment, the wiring harness of integrated pipeline 200 includes an electrical harness 202, a shielding gas delivery harness 203, and a coolant delivery harness 204. Specifically, electrical harness 202 is located at the center of sheath 201, while shielding gas delivery harness 203 and coolant delivery harness 204 are arranged around electrical harness 202. Of course, the wiring harnesses can also be arranged in other ways, not limited to the one discussed above.

[0031] Optionally, in this embodiment, if Figure 4 and Figure 5 As shown, the welding gun 300 includes a welding gun body 301, a rotating frame 302, a gas nozzle 303, and a connecting gas pipe 304. The rotating frame 302 is rotatably mounted on the welding gun body 301. The gas nozzle 303 is mounted on the rotating frame 302. The connecting gas pipe 304 is mounted on the welding gun body 301. One end of the connecting gas pipe 304 is connected to the gas nozzle 303, and the other end is connected to the shielding gas delivery harness 203 for delivering shielding gas. In a specific configuration, the rotating frame 302 is sleeved on the gun head of the welding gun body 301 and can rotate around the gun head. During use, by rotating the rotating frame 302, the position of the gas nozzle 303 relative to the gun head can be adjusted, so that the welding gun 300 can adapt to different welding angles.

[0032] Optionally, in this embodiment, if Figure 4 As shown, the gas nozzle 303 has an air jet surface 305 with a plurality of air outlet holes 306 evenly distributed thereon. In practice, the multiple air outlet holes 306 of the gas nozzle 303 can evenly spray shielding gas into the welding area, forming a stable shielding gas layer above the weld pool. This effectively isolates the air and prevents oxygen, nitrogen, and other gases in the air from adversely affecting the high-temperature weld pool and weld metal, such as oxidation and nitridation, thereby improving welding quality and reducing welding defects. In a specific configuration, the air jet surface 305 is a conical or curved surface. Of course, the air jet surface 305 can also be shaped in other ways, not limited to the one discussed above.

[0033] Optionally, in this embodiment, if Figure 6As shown, the welding gun body 301 is provided with a plurality of first limiting holes 307 along its circumference. The turret 302 is provided with second limiting holes 308 corresponding to the first limiting holes 307. When the turret 302 rotates, the second limiting holes 308 can be aligned with each of the first limiting holes 307. The welding gun 300 also includes a limiting rod 309, which is inserted into the first limiting holes 307 and the second limiting holes 308 to limit the rotation of the turret 302 relative to the welding gun body 301. This arrangement can achieve a positional lock between the turret 302 and the welding gun body 301.

[0034] Optionally, in this embodiment, if Figure 6 As shown, the welding gun 300 further includes a positioning frame 310, a retaining ring 311, and an elastic member 312. The positioning frame 310 is mounted on the rotating frame 302 and is provided with a mounting hole. A limiting rod 309 is axially movably disposed in the mounting hole of the positioning frame 310. When the limiting rod 309 moves axially within the mounting hole relative to the positioning frame 310, it can be inserted into the first limiting hole 307 and the second limiting hole 308 to restrict the rotation of the rotating frame 302 relative to the welding gun body 301, or can be withdrawn from the first limiting hole 307 and the second limiting hole 308 to allow the rotating frame 302 to rotate relative to the welding gun body 301. The retaining ring 311 is disposed on the side of the limiting rod 309 and moves with the limiting rod 309. The elastic member 312 is disposed between the retaining ring 311 and the positioning frame 310. The elastic member 312 is configured to restrict the limiting rod 309 from exiting the first limiting hole 307 and the second limiting hole 308 when no external force is applied. Specifically, when the limiting rod 309 is pulled out of the first limiting hole 307 and the second limiting hole 308, the retaining ring 311 squeezes or stretches the elastic member 312. When the pulling force disappears, the elastic member 312 returns to its original position under its own elastic force, and at the same time, the retaining ring 311 drives the limiting rod 309 to be reinserted into the first limiting hole 307 and the second limiting hole 308, thereby restricting the rotation of the rotating frame 302 relative to the welding gun body 301.

[0035] Optionally, in this embodiment, if Figure 4 and Figure 5 As shown, the welding gun 300 further includes a protective cover 313, which is provided at the gun head of the welding gun body 301. Specifically, during welding, the protective cover 313 faces the welding area to prevent sparks generated during welding from splashing and damaging surrounding equipment, facilities and construction personnel.

[0036] Optionally, in this embodiment, if Figure 1 and Figure 3As shown, the pipeline winding mechanism 400 includes a mounting frame 401, a winding shaft 402, and two end plates 403. The mounting frame 401 is mounted on the welding machine body 100 (such as the fixed base 150 or the fixed bracket of the gas cylinder 120). The winding shaft 402 is rotatably mounted on the mounting frame 401, and the winding shaft 402 is used to rotate circumferentially to wind up the integrated pipeline 200. The end plates 403 are arranged at both ends of the winding shaft 402, and the end plates 403 are used to limit the movement of the integrated pipeline 200 on the winding shaft 402. During specific use, the integrated pipeline 200 can be wound onto the winding shaft 402 by driving the winding shaft 402 to rotate. In specific implementation, the winding shaft 402 can be driven manually or by a motor. This embodiment of the present application does not specifically limit this.

[0037] Optionally, in this embodiment, if Figure 1 and Figure 3 As shown, the pipeline reeling mechanism 400 further includes a rocker 404, which is disposed at one end of the reeling shaft 402 and is used to drive the reeling shaft 402 to rotate circumferentially. During operation, an operator can operate the rocker 404 to rotate the reeling shaft 402, thereby reeling the integrated pipeline 200 onto the reeling shaft 402. Of course, the pipeline reeling mechanism 400 may also employ other methods for driving the reeling shaft 402, not limited to the method discussed above.

[0038] Optionally, in this embodiment, if Figure 3 As shown, the pipeline reeling mechanism 400 further includes a guide rod 405 and a pulling assembly. The guide rod 405 is parallel to the reeling shaft 402 and disposed between the two end plates 403. The pulling assembly is movably disposed on the guide rod 405 and is used to pull the integrated pipeline 200 along the axial direction of the guide rod 405 to adjust the winding position of the integrated pipeline 200. Specifically, when the reeling shaft 402 rotates circumferentially, the pulling assembly and the guide rod 405 can rotate about the axis of the reeling shaft 402. Simultaneously, the pulling assembly can move axially along the guide rod 405, thereby adjusting the winding position of the integrated pipeline 200 to ensure a more regular retraction of the integrated pipeline 200.

[0039] Optionally, in this embodiment, if Figure 3 As shown, the traction assembly includes a movable seat 406 and a traction member 407. The movable seat 406 is movably mounted on the guide rod 405. The traction member 407 is mounted on the movable seat 406 and has a through hole for passing the integrated pipeline 200. During operation, the integrated pipeline 200 is passed through the through hole of the traction member 407. When the movable seat 406 drives the traction member 407 to move axially along the guide rod 405, the integrated pipeline 200 passing through the through hole of the traction frame can move synchronously, thereby adjusting the winding position. Of course, the traction member 407 can also be configured in other ways, not limited to the one discussed above.

[0040] Optionally, in this embodiment, if Figure 3 As shown, the traction assembly further includes a rotating shaft 408, through which the traction member 407 is rotatably mounted on the movable seat 406. In this embodiment, the rotating shaft of the traction member 407 is parallel to the axis of the reel 402. When the traction assembly rotates about the axis of the reel 402, the traction member 407 can rotate relative to the movable seat 406 to adjust the bending angle of the integrated pipeline 200, thereby preventing damage to the integrated pipeline 200 due to excessive bending.

[0041] Optionally, in this embodiment, if Figure 3 As shown, the traction assembly further includes a screw 409, which is rotatably disposed between the two end plates 403 and threadedly engaged with the traction assembly (movable seat 406). Screw 409 is configured to rotate circumferentially to drive the traction assembly along the axial direction of the guide rod 405. Specifically, screw 409 and movable seat 406 can form a screw-nut mechanism. By driving screw 409 circumferentially, movable seat 406 can be moved axially along the guide rod 405. In a specific implementation, screw 409 can be driven by an electric motor or a pneumatic motor. This is not specifically limited in this embodiment of the present application.

[0042] Optionally, in this embodiment, if Figure 3 As shown, the pipeline reeling mechanism 400 further includes a fixed gear 410 and a movable gear 411. The fixed gear 410 is mounted on the mounting frame 401, and the movable gear 411 is mounted on the screw 409 and meshes with the fixed gear 410. The movable gear 411 is configured to roll with the fixed gear 410 during circumferential rotation of the reeling shaft 402, thereby driving axial rotation of the screw 409. Specifically, the fixed gear 410 is fixed to the mounting frame 401, with the axis of the fixed gear 410 coinciding with the axis of the reeling shaft 402. The movable gear 411 is sleeved onto the end of the screw 409. When the screw 409 rotates about the axis of the reeling shaft 402, the movable gear 411 can rotate about the axis of the fixed gear 410. As the movable gear 411 rotates about the axis of the fixed gear 410, the teeth of the two gears engage, causing the movable gear 411 to rotate (circumferentially), thereby driving the circumferential rotation of the screw 409. In a specific implementation, the gear teeth of the fixed gear 410 can be arranged on the outer circumference or the inner circumference, which is not specifically limited in this embodiment of the present application.
