Technical Field

[0001] The utility model relates to the technical field of automatic welding, in particular to an automatic titanium flanging welding machine. Background Art

[0002] Due to the rapid temperature rise during arc welding, titanium welds are prone to oxidation. The actual welding process typically requires the coordinated efforts of multiple individuals: one person holding the welding torch and two individuals holding separate gas shields to provide real-time gas shielding above and below the weld seam. This requires not only skilled coordination but also extremely low welding efficiency, high production costs, and poor product consistency. Utility Model Content

[0015] The following will be combined with the accompanying drawings of the present invention to clearly and completely describe the technical solution of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0016] according to Figure 1 、 Figure 2 、 Figure 3 As shown, a titanium flanging automatic welding machine comprises: a frame 1, a workbench 2 is provided at the front end of the frame 1, a hollow spindle 3 is longitudinally arranged on the workbench 2, and a servo motor driving the hollow spindle 3, an air inlet is provided at the bottom end of the hollow spindle 3, and the air inlet is connected to the protective gas cylinder 18 through a first solenoid valve; a pneumatic chuck 4, the pneumatic chuck 4 is arranged at the top of the hollow spindle 3, and the pneumatic chuck 4 is connected to the power gas source through a second solenoid valve; a support tube 5, the support tube 5 is fixedly arranged at the center of the top of the pneumatic chuck 4, and a through hole is provided in the center of the support tube 5 that is connected to the interior of the hollow spindle 3; A floating sealing cover 6, wherein an air guide chamber is provided at the top of the floating sealing cover 6, a conduit 7 extending toward the inside of the hollow main shaft 3 is provided at the center of the top of the air guide chamber, and a plurality of air holes 20 are distributed at the bottom of the air guide chamber; a lifting arm 8, wherein the lifting arm 8 is located above the workbench 2 and is connected to the top of the frame 1, and an adjustable bracket 9 is provided at the bottom of the telescopic end of the lifting arm, and a welding gun 10 is clamped at the free end of the adjustable bracket 9; a controller 11, wherein the controller 11 is arranged on one side of the frame 1, and the servo motor, the first solenoid valve, the second solenoid valve and the welding gun 10 are electrically connected to the controller 11 respectively.

[0017] Through the above arrangement, when the flange workpiece is circumferentially welded, the pneumatic chuck 4 is first used through the controller 11 to horizontally clamp the flange workpiece, and then the straight cylindrical workpiece to be welded to the flange workpiece is positioned on the top of the flange component, and the floating sealing cover 6 passes through the straight cylindrical component through the conduit 7 and is inserted into the hollow main shaft 3. At this time, the floating sealing cover 6 uses its own gravity to press on the straight cylindrical workpiece and close the opening at the top of the straight cylindrical workpiece. The staff adjusts the lifting arm 8 so that the telescopic end is at the lower dead point, and uses the adjustable bracket 9 to put the welding gun 10 and the weld of the workpiece into position and locks the adjustable bracket 9. At this time, the setting of the automatic welding machine is completed. During the welding process, the controller 11 coordinates the servo motor, the first solenoid valve, the second solenoid valve and the welding gun 10 to complete the circumferential welding of the workpiece. In this process, the shielding gas is ejected through the welding gun 10 on the one hand to protect the top of the weld, and the floating sealing cover 6 also fills the bottom support tube 5 with shielding gas to meet the protection requirements of the bottom of the weld. Compared with the traditional welding process, the titanium metal flanging automatic welding machine is far superior in production efficiency, appearance structure, use process and number of operators. Because of the traditional welding method, it does not require multiple people to cooperate to manually locate the weld position, nor does it require multiple people to cooperate to hold the shielding gas shield, thereby avoiding the workers' coordination and synchronization, which leads to the weld effect not meeting the expected effect, poor product quality stability and low finished product qualification rate. The titanium metal flanging automatic welding machine is easy to operate and operates with intelligent numerical control, which greatly reduces the professional and technical requirements for workers, saves labor, time and raw materials, and greatly improves the market competitiveness of the product.

[0018] A first tray 14 and a second tray 15 are arranged side by side at the bottom of the rear end of the frame 1, and a third tray 16 is arranged above the first tray 14; a welding machine body 17 is fixed in the first tray 14, and the shielding gas cylinder 18 is fixed in the second tray 15, and a wire feeder 19 is arranged on the third tray 16, and the welding gun 10 is respectively connected to the welding machine body 17, the wire feeder 19 and the shielding gas cylinder 18 through the welding handle wire.

[0019] With this arrangement, the welding machine body 17, the shielding gas cylinder 18 and the wire feeder 19 are respectively placed behind the frame 1, thereby reducing the impact on the welding operation and ensuring the smooth progress of the welding work.

[0020] An annular groove 12 is circumferentially provided on the top of the support tube 5 , and the annular groove 12 is connected to the interior of the hollow main shaft 3 through a channel.

[0021] In this arrangement, the annular groove 12 also guides the shielding gas into the support tube 5 and increases the shielding gas content in the support tube 5, thereby improving the protection of the weld bottom.

[0022] It also includes a sealing ring 13, which is arranged around the top outer edge of the support tube 5.

[0023] This arrangement supports and fits the bottom of the workpiece through the sealing ring 13, thereby improving the airtightness between the bottom of the workpiece and the support tube 5 and preventing leakage of the protective gas.

[0024] A cylinder is provided between the telescopic end of the lifting arm 8 and the frame 1 . The cylinder is connected to a power gas source via a third solenoid valve, and the third solenoid valve is electrically connected to the controller 11 .

[0025] Through this setting, when the position of the welding gun 10 is set, the controller 11 can control the lifting action of the lifting arm 8 through the third solenoid valve to achieve automatic resetting after the workpiece welding is completed, meeting the automated welding requirements of the workpiece.

[0026] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
