[0003] Automatic welding equipment generally includes welding actuators, welding power supplies, controllers and cooling systems, etc. The welding actuators mainly include clamping parts, actuator bodies, rotating motion parts, wire feeding parts, welding gun height and swing motion parts, welding guns, etc. During on-site welding, the welding actuators must be fixed on the pipes to be welded.
[0004] Some welds are located in narrow spaces, where manual welding cannot be performed and automated welding is required. The general standard automatic welding actuator is too large to meet the welding requirements of welds in narrow spaces. On the other hand, in order to ensure the quality of welding in narrow spaces, it is necessary to observe the welding molten pool in real time to determine the real-time weld formation quality and adjust the welding parameters according to the molten pool shape. Therefore, it is necessary to add a molten pool observation component to the welding actuator, which further increases the size of the welding actuator, making automated welding in narrow spaces impossible to implement.

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0020] At least one embodiment of the present application provides an automatic welding actuator, which is mainly used for automatic welding of small and medium-sized pipes in narrow spaces and real-time observation of the welding pool during the welding process. Figure 1 and Figure 2 The automatic welding actuator includes a molten pool observation component 1, a welding gun 2, a clamping component 3, a rotating motion component 4, a mounting rotary disk 5, a mounting seat 6, a welding gun connecting rod 7, a motor connecting rod 8, a welding gun height motion component 9, a wire feeding component 10 and a welding gun swing motion component 11. The welding gun 2 is mainly used for the generation of arc during welding, and realizes the connection of the pipeline by melting the parent material and the welding wire. It is installed on the welding gun connecting rod 7 by bolts. The mounting rotary disk 5 is connected and driven with the rotating motion component 4 by a rotating ring and a chain. The rotating motion component 4 is installed together with the clamping component 3. The clamping component 3 is used to realize the clamping of the entire automatic welding actuator on the pipeline. The welding gun connecting rod 7 and the motor connecting rod 8 are both installed on the mounting seat 6, and then installed as a whole on the mounting rotary disk 5. The wire feeding component 10 is mainly used for continuously feeding the welding wire into the lower part of the welding gun during welding, melting it under the action of the arc, and finally forming a weld on the parent material of the welded pipeline, and is installed on the welding gun connecting rod 7 by bolts. The welding gun swing motion component 11 is mainly used for adjusting the left and right position of the welding gun 2 along the weld direction before and during welding and swing welding. The actuator body is installed on the rotating disk, and one end of the transmission component of the welding gun swing motion component 11 is fixed to the motor connecting rod 8.
[0021] It should be noted that the welding gun connecting rod 7 and the motor connecting rod 8 can be mounted on the mounting seat 6 by bolts, and then integrally mounted on the mounting rotating disk 5 .
[0022] According to the technical solution provided in the embodiment of the present application, the modular, compact, and customized connecting rod structure realizes the automated welding of small and medium-sized pipes in narrow spaces on site and the real-time observation of the welding molten pool during the welding process, which ensures the implementation of welding and improves the welding quality. In addition, the customized design and installation of the motor connecting rod ensure the consistency of the adjustment of the welding gun swing motion component and the welding gun height motion component. In addition, through the intensive design of the welding gun connecting rod structure, the molten pool observation component, the wire feeding component, the welding gun swing motion component, and the welding gun height motion component, it is ensured that no matter how the welding gun moves, the molten pool observation component follows synchronously, ensuring that the field of view of the welding molten pool remains unchanged.
[0023] In at least one embodiment of the present application, reference Figure 3 The molten pool observation component 1 includes a fixed bracket 12, a molten pool observation mounting bracket 13, a corner component 14, a camera hoop 15 and a camera 16. The camera 16 is mounted on the fixed bracket 12 through a hoop and bolts; the corner component 14 is mounted on the fixed bracket 12 through bolts; the fixed bracket 12 is connected to the molten pool observation mounting bracket 13 through bolts. The molten pool observation component 1 is connected to the welding gun 2 through the molten pool observation mounting bracket 13 and the bolts. In this way, the molten pool observation component corner design ensures that the molten pool light beam reaches the camera through reflection in a narrow space, realizes molten pool observation, and greatly reduces the structural size of the camera facing the molten pool observation.
[0024] In at least one embodiment of the present application, reference Figures 4 to 7 , the corner component 1 includes a shell 17, an upper cover plate 18, a front cover plate 19, a protective film 20, screws 21, bolts 22, a fixing plate 23, a washer 24 and a reflector 25.

The entire corner component 14 is installed on the fixed bracket 12 through the bolt holes and bolts 22 on the shell 17. In this way, during the welding process, the molten pool and the surrounding light beam first pass through the protective film 20, and then under the action of the reflector 25, the light beam changes its path and enters the camera 16 for image acquisition, processing and transmission; then with the help of a computer and software, remote visual observation of the welding molten pool is realized.
[0025] In at least one embodiment of the present application, the reflector 25 is made of stainless steel.
