Description

Technical Field

[0001] This utility model relates to the field of welding technology for air conditioning parts, and in particular to a nitrogen-protected welding turntable. Background Technology

[0002] In the production of air conditioning components, large parts, as one of the core components, directly affect the overall production efficiency of the entire unit due to the efficiency of their piping and welding. Currently, long workbenches are commonly used on production sites for welding air conditioning components. However, when using these fixed long workbenches, piping and welding personnel need to constantly move to complete the piping and welding operations, resulting in overlapping work among personnel. This not only easily causes mutual interference and affects the continuity of work, but also increases safety risks, such as burns during welding.

[0003] Furthermore, the frequent movement of workers results in high labor intensity and hinders efficiency. Actual data shows that completing the welding of a single air conditioner component using a traditional long workbench takes an average of 136.23 seconds, making low efficiency a production bottleneck.

[0004] Therefore, existing air conditioning components suffer from low efficiency, high labor intensity, and significant safety hazards during welding and piping. There is an urgent need for a new type of welding device that can improve the work process, increase work efficiency, and reduce labor intensity. Summary of the Invention

[0009] Preferably, the rotating seat is provided with at least two connecting pipes, and the air outlet can be selectively connected to one of the connecting pipes. The connecting pipe is connected to the air outlet on the turntable through a protective gas output pipe to realize gas supply.

[0010] Preferably, a sealing ring is provided between the rotating seat and the gas distributor to ensure gas tightness during rotation.

[0011] Preferably, the drive mechanism includes a motor, a drive gear, a driven gear, and a transmission chain. The motor is fixed on the frame, the drive gear is connected to the motor output shaft, and the driven gear is mounted on the rotating seat.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] like Figures 1 to 3 As shown, the present invention provides a nitrogen-protected welding turntable, which mainly includes a frame 1, a turntable 2, a drive mechanism, and a gas supply system. The turntable 2 is rotatably mounted above the frame 1 via a rotating base 5. The drive mechanism is used to drive the turntable 2 to rotate intermittently or continuously. The gas supply system is used to continuously supply protective gas to the welding area during the rotation of the turntable 2 to achieve the effect of preventing oxidation.

[0024] Specifically, the frame 1 is a square frame structure welded from structural steel, possessing sufficient strength and stability. A frame mounting base 13 is fixedly installed at the center of the upper surface of the frame 1. The frame mounting base 13 is connected to the frame 1 by screws, facilitating installation and disassembly.

[0025] The turntable 2 has a circular structure, with a product fixing and processing area 3 on its upper part for placing large components such as air conditioner outdoor units to be welded. An air vent 301 is located above the product fixing and processing area 3 to guide protective gas to the welding area. A rotating base 5 is fixedly connected to the bottom surface of the turntable 2, and the turntable 2 and the rotating base 5 are connected by screws to ensure structural stability.

[0026] The rotating seat 5 and the frame mounting seat 13 are rotatably connected by a bearing 12. The outer ring of the bearing 12 mates with the frame mounting seat 13, and the inner ring mates with the rotating seat 5, so that the turntable 2 can rotate smoothly relative to the frame 1.

[0027] The gas supply system includes a protective gas input pipe 10 and a gas distributor 11. The gas distributor 11 has a conical column structure, is fixedly installed in the middle of the frame mounting base 13, and extends upward into the inner cavity of the rotating seat 5. The gas distributor 11 has an internal gas passage 1101, the lower end of which is connected to the protective gas input pipe 10, and the upper end has an obliquely oriented gas outlet 1102. The lower end of the gas distributor 11 extends to the outside of the frame mounting base 13 for easy connection to an external protective gas source.

[0028] At least two connecting pipes 502 are provided circumferentially within the inner cavity of the rotating seat 5. During the rotation of the turntable 2, the air outlet 1102 can sequentially align and connect with different connecting pipes 502. The connecting pipes 502 are connected to the air outlet 301 on the turntable 2 via a protective gas output pipe 4 to achieve gas supply. To ensure gas sealing, a sealing ring 501 is provided between the rotating seat 5 and the gas distributor 11, forming a rotary sealing structure.

[0029] The drive mechanism includes a motor 9, a drive gear 8, a driven gear 6, and a transmission chain 7. The motor 9 is fixed to the frame 1 by a mounting plate, and the drive gear 8 is mounted on the output shaft of the motor 9. The driven gear 6 is fixedly mounted on the outer periphery of the rotating seat 5, and the drive gear 8 meshes with the driven gear 6 through the transmission chain 7. When the motor 9 starts, it drives the rotating seat 5 and the turntable 2 to rotate together through the transmission chain 7.

[0030] The working process of this utility model is as follows: The workpiece to be welded is fixed on the product fixing processing area 3 of the turntable 2. The motor 9 is started, and the turntable 2 rotates according to the set rhythm, sequentially sending the workpiece to different workstations for piping or welding operations. At the same time, the protective gas enters the gas passage 1101 of the gas distributor 11 from the protective gas input pipe 10, passes through the gas outlet 1102, the connecting pipe 502 and the protective gas output pipe 4, and is finally continuously sprayed out from the gas outlet 301, covering the welding area and forming local protective nitrogen gas, which effectively prevents metal oxidation.

[0031] This invention achieves automatic workpiece transfer through turntable rotation, avoiding frequent personnel movement and cross-operations, thus improving operational safety and continuity; it integrates nitrogen protection to ensure welding quality; the overall structure is compact and the transmission is stable, making it particularly suitable for welding air conditioning components.
