[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] like Figures 1-6 The linear dual-triaxial flame brazing equipment shown is used for welding aluminum parts and consists of a brazing station 1, a triaxial welding system, a protective shell 5, a cooling system, an ignition mechanism, a safety monitoring system, a control cabinet, and a suspended touch screen 7.

[0019] The brazing station 1 is the basic support structure of the entire equipment. It is equipped with a cooling water tray 2 and a tooling support aluminum material 3. The cooling water tray 2 is used to hold cooling water. The tooling support aluminum material 3 is set in the cooling water tray 2 and is used to place the aluminum parts to be welded, providing a stable working platform for welding operations. At the same time, the water in the cooling water tray 2 can cool the tooling support aluminum material 3 and aluminum parts, effectively controlling the temperature during the welding process, reducing the heat-affected zone, and preventing deformation of aluminum parts. The cooling water tray 2 is also equipped with a drain pipe at the bottom. The drain pipe can be connected to external purification equipment, and the purified cooling water re-enters the cooling water tank 8.

[0020] The triaxial welding system includes at least one triaxial welding component 4, such as Figure 2 As shown, two symmetrical triaxial welding components 4 are generally set. Both triaxial welding components 4 are located on one side of the cooling water pan 2. Each triaxial welding component 4 includes an X-axis module, a Y-axis module, a Z-axis module and a flame welding torch 12. Through the combination of movements in three directions, the flame welding torch 12 is precisely positioned in space, thereby meeting the welding requirements of different aluminum parts and improving welding accuracy and efficiency.

[0021] X-axis module: fixed on brazing station 1, providing a track for the lateral movement of the Y-axis module; Y-axis module: Slidably mounted on the X-axis module and driven by the X-axis servo motor, it can move precisely in the X-axis direction to adjust the lateral position of the flame welding torch 12; Z-axis module: Slidably mounted on the Y-axis module and driven by the Y-axis servo motor, it can move precisely in the Y-axis direction to further adjust the longitudinal position of the flame welding torch 12; When the three-axis module is driven, the servo motor and the synchronous belt 405 work together to drive the corresponding mechanism to move.

[0022] Flame welding torch 12: It is mounted on the Z-axis module via a sliding component 404 and is driven by a Z-axis servo motor to move along the Z-axis, thereby achieving vertical position adjustment of the flame welding torch 12.

[0023] The sliding assembly 404 includes an L-shaped sliding frame 408, a guide rail mounting plate 411, a swing drive mechanism, a vertical guide rail 412, and a lifting cylinder.

[0024] L-shaped sliding frame 408: Its upright plate 4081 is slidably connected to the Z-axis module to realize the connection and sliding with the Z-axis module, and its horizontal plate 4082 is fixed on the guide rail mounting plate 411 to provide support for the guide rail mounting plate 411.

[0025] Guide rail mounting plate 411: Slidably mounted on linear guide rail 410, providing a basic platform for the installation and movement of flame welding torch 12.

[0026] The swing drive mechanism includes a swing motor 409, an eccentric block 414, and a fisheye connector 415. The swing motor 409 is connected to a motor reducer 413. The eccentric block 414 is concentrically connected to the output shaft of the reducer. The fisheye connector 415 is hinged at both ends to the sides of the eccentric block 414 and the guide rail mounting plate 411, respectively, and the fisheye connector 415 and the eccentric block 414 are eccentrically hinged. When the swing motor 409 is started, the eccentric block 414 rotates, which drives the guide rail mounting plate 411 to reciprocate along the linear guide rail 410 through the fisheye connector 415, thereby causing the flame welding torch 12 to reciprocate, which helps to improve the uniformity of heat distribution during the welding process and improve the welding quality.

[0027] Vertical guide rail 412: Its lower part is connected and fixed to the guide rail mounting plate 411, and the upper part is provided with a guide rail structure. The upper part of the vertical guide rail 412 is provided with a sliding seat 416 that slides with it. The flame welding gun 12 is fixed on the sliding seat 416 to realize the precise movement of the flame welding gun 12 in the vertical direction.

[0029] The protective shell 5 covers the brazing station 1 and provides protection, preventing sparks and spatter generated during the welding process from causing injury to the operator. The top is equipped with a fume extraction pipe interface 6, which can be connected to fume extraction equipment to promptly remove fumes and harmful gases generated during the welding process, improve the working environment, and protect the health of the operator.

Figure 3 As shown, various types of spray nozzles can be installed on the water spray pipe 9. The water pump delivers cold water from the cooling water tank 8 to the water spray pipe 9. The water spray pipe 9 sprays cooling water toward the tooling support aluminum material 3, further enhancing the cooling effect on the welding area of ​​the aluminum parts, ensuring that the temperature of the aluminum parts is effectively controlled during the welding process, and improving the welding quality.

[0031] The ignition mechanism includes a liftable ignition shaft 10 and a lifting mechanism that drives its lifting. The ignition shaft 10 is set on the brazing station 1 and located below the triaxial welding assembly 4. It works with the flame nozzle 1206 in the triaxial welding assembly 4 to complete ignition. The lifting mechanism can be a cylinder or an electric lifting rod. By controlling the lifting of the ignition shaft 10 through the lifting mechanism, the flame nozzle 1206 can be automatically ignited, improving the convenience and safety of operation.

[0032] The guide rail mounting plate 411 is equipped with a material detection sensor 406 at the bottom, which is used to detect the spatial position of the workpiece on the tooling support aluminum material 3, provide position feedback for the three-axis welding system, ensure that the flame welding gun 12 can accurately weld the workpiece, and improve the welding accuracy.

[0033] The safety monitoring system includes a gas alarm 11 and a linkage controller. The gas alarm 11 is used to monitor for gas leaks in the gas supply pipeline. Once a gas leak is detected, an alarm is immediately triggered. The linkage controller responds to the signal from the gas alarm 11 and quickly cuts off the gas supply, effectively preventing safety accidents caused by gas leaks and ensuring the safety of equipment and personnel.

[0034] Gas supply pipelines: including independent gas supply pipelines and combustion-supporting gas pipelines, with quick-shut-off valves at each pipeline branch node to facilitate rapid gas supply cut-off in emergencies and improve safety.

[0035] Control cabinet: Integrated inside the brazing station 1, it receives signals from various sensors such as material detection sensor 406, and controls the actuators according to the preset program, such as the movement of the triaxial welding system, the operation of the flame welding torch 12, and the operation of the cooling system, so as to realize the automated control of the equipment.

[0036] Suspended touch screen 7: Located on the outside of the protective housing 5, it is connected to the control cabinet. Operators can intuitively set equipment parameters and monitor equipment operation status through the touch screen, improving the convenience of operation and the intelligence of the equipment.

[0037] It should be noted that the safety monitoring system, gas supply pipeline, control cabinet, and hanging touch screen 7 can all be applied to this equipment using mature technologies or with simple modifications.

[0038] The flame welding torch 12 includes a torch rod 1201, a multi-hole torch head 1202, and a gas source interface; Gun barrel 1201: A sliding seat 416 fixed above the lifting cylinder, with an air source inlet 1204 at its rear.
