Description

Technical Field

[0001] This invention relates to a production welding apparatus, and more particularly to a modular welding assembly equipment for launch tubes. Background Technology

[0002] A warhead-carrying, self-powered aircraft guided by a mid-course guidance system to its target and destroy it is typically composed of a warhead, control system, engine, and missile body. Launch requires the assistance of a launch tube. Because the launch angle and position vary, angle adjustment is achieved through the extension and retraction of an electric cylinder. Therefore, during launch, the electric cylinder and moving parts must cooperate, necessitating welding assembly, which requires the use of welding equipment in the manufacturing process.

[0003] The current method of manually welding electric cylinders and moving parts is laborious, resulting in low welding efficiency and poor quality. Furthermore, the need to disassemble and reassemble the welded electric cylinder and connecting parts under the welding torch significantly reduces safety. Because the connection between the electric cylinder and connecting parts is an interlocking weld, slippage is prone to occur during assembly, affecting welding accuracy. Additionally, traditional welding devices cannot automatically adjust the welding position by rotating the electric cylinder and connecting parts, resulting in poor usability. Moreover, the lack of synchronous cooling and coolant filtration and recovery functions during welding compromises welding and energy efficiency. Therefore, a highly automated, user-friendly, and efficient welding device for launching tube production is needed to ensure production efficiency and quality. Summary of the Invention

[0004] The purpose of this invention is to provide a modular welding assembly equipment for launch tubes, in order to solve the problems mentioned in the background art, such as low automation during the welding process of electric cylinders and connectors, the need for manual welding with a handheld welding gun, low welding efficiency, inability to accurately position and rotate the electric cylinder and connectors, and lack of synchronous cooling and coolant filtration and recovery functions after welding, which to some extent reduce the ease of use, welding accuracy, welding effect and efficiency.

[0007] As a preferred embodiment of the present invention, the push rod assembly includes an electric cylinder, the fixed end and the telescopic end of which are respectively engaged between two upper clamping plates and a lower clamping plate, and mounting screw holes are provided on both ends of the electric cylinder.

[0008] In a preferred embodiment of the present invention, the welding assembly includes two support frames, which are fixedly connected to the top of a support platform. A first bearing is fixedly connected to the top of each support frame, and a hollow shaft is rotatably connected within the first bearing. A turntable is fixedly connected to the bottom end of the hollow shaft, and a welding torch and a flushing head are fixedly mounted on the surface of the turntable. A conduit is fixedly connected to the top of the flushing head, and one end of the conduit is fixedly connected to the surface of the hollow shaft. A rotary joint is fixedly connected to the top of the hollow shaft, and a delivery pipe is fixedly connected to the top of the rotary joint.

[0011] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting up welding components and conveying components, uses a first motor to drive a first gear to mesh with a transmission gear and rotate. With the help of a first transmission belt, the hollow rotating shaft, in cooperation with a rotary joint, drives the turntable to rotate, thereby driving the welding torch and the rinsing head to rotate.

This invention, by setting up a clamping assembly, uses a dual-axis motor to drive the second gear to rotate. The second gear meshes with two half-gear rings, enabling the upper and lower clamping plates to drive the electric cylinder and the movable shaft to rotate automatically, thus achieving the purpose of switching between the upper and lower parts. This allows for separate welding of the upper and lower connection positions of the electric cylinder and the movable shaft, improving ease of use. 3. This invention achieves positioning between the electric cylinder and the movable shaft by setting up a connecting rod assembly and a push rod assembly, and by using the threaded connection between the positioning screw and the mounting screw hole. This avoids the situation where sliding misalignment caused by directly using the insertion method affects the welding effect, and ensures welding accuracy. 4. By setting up a coolant reservoir and filter plate, the coolant can be filtered and recycled after use in conjunction with the flushing head, achieving the purpose of recycling and improving energy saving.

One end of the liquid pump 41 is located in the coolant storage chamber 11, and the other end of the liquid pump 41 is fixedly connected to the delivery pipe 42. A filter plate 12 is snapped into the top of the coolant storage chamber 11. A limit frame 44 is fixedly connected to the top of the support frame 43. The delivery pipe 42 passes through the limit frame 44. A signal receiver 10 is fixedly installed on the inner side of the support frame 43.

[0022] Specific operation method of the present invention: When it is necessary to assemble and weld the electric cylinder 61 and the movable shaft 71, firstly, the positioning screw 72 can be threaded into the mounting screw hole 62 to complete the positioning assembly between the electric cylinder 61 and the movable shaft 71. Then, the controller 3 controls the electromagnet to be de-energized, the upper clamping plate 88 is moved upward, the assembled electric cylinder 61 and the movable shaft 71 are placed on the lower clamping plate 83, and the upper clamping plate 88 is moved downward to fit against the lower clamping plate 83. The electromagnet is energized to perform electromagnetic adsorption and fixation, and the installation is completed. Then, the controller 3 controls the second motor 131 to work, driving the transmission wheel 132 to rotate. Through the transmission action of the second transmission belt 133, the second rotating shaft 134 drives the transmission roller 137 to rotate, causing the conveyor belt 136 to drive the connecting plate 81 to move. This allows one set of electric cylinders 61 and the movable shaft 71 to be transported to below the turntable 413. Positioning is achieved through signal connection between the signal transmitter 9 and the signal receiver 10. Then, the controller 3 controls the welding torch 416 to work for welding, and also controls the first motor 410 to work, driving the first gear 49 to mesh with the transmission gear 411. The hollow shaft 47 rotates, driven by the first transmission belt 46 and the rotary joint 45, causing the turntable 413 to rotate, which in turn causes the welding torch 416 to perform welding. During the welding process, the controller 3 controls the pump 41 to work, which delivers the coolant in the coolant storage chamber 11 to the flushing head 415 through the delivery pipe 42, the rotary joint 45 and the hollow shaft 47 via the conduit 414. As the flushing head 415 rotates, it cools the weld in time to ensure the welding effect. After use, the coolant is filtered by the filter plate 12 and then enters the coolant storage chamber 11 for recooling and recycling. After welding at one end, the controller 3 controls the dual-axis motor 85 to work, which drives the second gear 86 to mesh with the two half-gear rings 82 and rotate. With the help of the rotation of the limit slider 89 in the limit slide rail 87, the upper clamping plate 88 and the lower clamping plate 83 drive the electric cylinder 61 and the movable shaft 71 to rotate, so that the bottom movable shaft 71 rotates to below the turntable 413. The above steps are repeated for welding again. After welding, the electric cylinder 61 and the movable shaft 71 are conveyed by the rotating conveyor belt 136. The workers can disassemble the welded electric cylinder 61 and the movable shaft 71 on the other side and reinstall the assembled but unwelded electric cylinder 61 and the movable shaft 71 in the upper clamping plate 88 and the lower clamping plate 83 for continued conveying. Meanwhile, the unwelded electric cylinder 61 and movable shaft 71 continue to be conveyed to the bottom of the turntable 413, and the above steps are repeated for continuous welding to ensure welding efficiency. After a period of use, the filter plate 12 can be removed for cleaning and replacement. At the same time, coolant can be added to the coolant reservoir 11 to ensure normal use.
