Description

Technical Field

[0001] This utility model belongs to the field of welding equipment, and relates to automated welding equipment, particularly to automated welding equipment for branch pipes of multi-interface fluid components. Background Technology

[0002] Multi-interface fluid components are workpiece types with spatially distributed branch pipes / interfaces (such as manifolds, valve bodies, and manifolds). Among them, manifolds, as the core distribution device of fluid transport systems, are widely used in HVAC, industrial water supply, petrochemical and other fields. Their typical structure includes a main pipe and multiple spatially distributed branch pipe interfaces, which are used to realize the diversion or confluence control of the medium.

[0003] Traditional multi-interface fluid component branch pipe welding process relies heavily on manual operation. When the branch pipe / interface axis is distributed at a non-orthogonal spatial angle with the main pipe, the welding torch trajectory needs to match the three-dimensional curved surface path in real time. Manual adjustment carries the risk of angle deviation. When welding multiple branch pipes continuously, the heat accumulation effect is significant, which can easily lead to excessive ellipticity of the main pipe, affecting the assembly accuracy of subsequent branch pipes. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing an automated welding equipment for multi-interface fluid component branch pipes, thereby solving these problems.

[0005] The purpose of this utility model can be achieved through the following technical solution: an automated welding equipment for branch pipes of multi-interface fluid components, characterized in that it includes a control system, a workbench, a tooling carriage for clamping and positioning fluid components, a conveyor belt mechanism for transporting and moving fluid components, and a feeding mechanism for directional conveying of branch pipes.

[0006] The workbench is provided with a slide rail and a truss spanning above the slide rail. The tooling carriage can move along the slide rail. The truss is equipped with a clamping and transporting mechanism for grabbing fluid components from the conveyor belt and transferring them to the tooling carriage.

[0007] A pre-assembly mechanism is provided between the feeding mechanism and the tooling car to pre-connect the branch pipe to the designated interface of the fluid component;

[0008] The truss is also equipped with a welding mechanism for welding the connection between the branch pipe and the fluid component. The welding mechanism includes a clamping component and a welding component. The clamping component clamps and positions the pre-inserted branch pipe by driving a cylinder to lift and lower.

[0009] The clamping and transporting mechanism cooperates with the conveyor belt mechanism to form a loading and unloading station, the pre-assembly mechanism cooperates with the feeding mechanism to form a pre-assembly station, and the welding mechanism completes the clamping and welding of the branch pipe under the command of the control system.

[0010] In the aforementioned automated welding equipment for branch pipes of multi-interface fluid components, the slide rail extends longitudinally or laterally along the worktable, the tooling carriage moves along the slide rail via a motor, and the truss is arranged parallel to the slide rail.

[0011] In the aforementioned automated welding equipment for branch pipes of multi-interface fluid components, the clamping assembly includes a pressure rod that is controlled to rise and fall by a drive cylinder and a replaceable clamping head located at the end of the pressure rod. The welding assembly includes a pressure rod that is controlled to rise and fall by a drive cylinder, a welding head for welding branch pipes, a rotating device connected to the welding head and used to drive the welding head to rotate circumferentially, and an angle adjusting device for adjusting the angle of the welding head. The welding head achieves multi-directional welding through the rotating device and the angle adjusting device.

[0012] In the aforementioned automated welding equipment for branch pipes of multi-interface fluid components, the angle adjustment device includes an adjustment plate with an arc-shaped structure, a connecting bracket mounted on a rotating device, and a drive motor. The adjustment plate has teeth at its corresponding outer edge, and the output end of the drive motor has adjustment teeth that mesh with the teeth. The adjustment plate achieves welding head angle adjustment by meshing the teeth with the adjustment teeth of the drive motor.

[0013] In the aforementioned automated welding equipment for branch pipes of multi-interface fluid components, the welding head is fixed to the end of the adjusting plate. The adjusting plate has a guide hole for easy angle adjustment, and its connecting bracket has a connecting wheel that cooperates with the guide hole. The adjusting plate achieves a movable limit connection through the cooperation of the connecting wheel and the guide hole.

[0014] In the aforementioned automated welding equipment for branch pipes of multi-interface fluid components, the welding mechanism further includes a connecting seat, which can move laterally along the truss. The rotating device and the driving cylinder are fixed on the connecting seat, and the pressure rod is coaxially arranged with the rotating device.

[0015] In the aforementioned automated welding equipment for branch pipes of multi-interface fluid components, the feeding mechanism includes a material box, a feeding track, and a branch pipe sorting device. The feeding track is connected to the material box and is used for conveying and feeding branch pipes.

[0016] In the aforementioned automated welding equipment for branch pipes of multi-interface fluid components, the pre-assembly mechanism includes a receiving robot, an assembly robot, and a turntable. The assembly robot rotates circumferentially on the turntable to pre-insert the branch pipe into the designated interface of the fluid component.

[0017] In the aforementioned automated welding equipment for multi-interface fluid component branch pipes, the clamping and transporting mechanism includes two clamping manipulators linked by a synchronizing element, used to grab fluid components from the conveyor belt and transfer them to the tooling car. The conveyor belt mechanism is symmetrically arranged on both sides of the workbench for automatic loading and unloading of fluid components.

[0018] Compared with existing technologies, this automated welding equipment for multi-interface fluid component branch pipes has the following advantages:

[0019] 1. Through the coordination of conveyor belts, gripping robots, and pre-assembly mechanisms, the entire process of loading and unloading, branch pipe pre-assembly, and welding is automated, reducing manual intervention. At the same time, the gripping robots are linked with the synchronization components to ensure the consistency of fluid component positioning. The angle adjustment device of the welding mechanism can be adapted to complex welds. The angle adjustment device replaces multi-axis robots. The welding angle changes while the welding positioning remains unchanged. It has low cost, fast welding speed, and the welding head can be laser welded, reducing the positioning pre-welding process and improving welding efficiency.

[0020] 2. The dual conveyor belt design enables parallel loading and unloading, seamless connection between pre-assembly and welding processes, significantly shortening the production cycle. Furthermore, the rigid structure design of the truss and slide rails ensures the stability of the equipment during high-speed operation and reduces vibration errors.

[0021] 3. The clamping head is detachable and replaceable, and the feeding track supports the sorting of multiple specifications of branch pipes, making it suitable for the production of multiple models of fluid components. Attached Figure Description
