Description

Technical Field

[0001] This utility model belongs to the technical field of welding tools for welding ring-shaped workpieces, and specifically relates to a horizontal ring-shaped workpiece welding platform. Background Technology

[0002] Ring-shaped workpieces, such as pipes, typically require gas shielded welding. Current technologies usually employ manual or robotic welding, but this necessitates moving the welding torch along an arc or circle, often resulting in suboptimal welding efficiency and stability. To address this, ring-shaped workpiece mounting platforms have been developed. Users can clamp the ring-shaped workpiece onto the platform, rotate it using its pivot, and then manually, robotically, or with a fixture, align the welding torch with the workpiece's welding point to achieve arc or ring welding.

[0003] However, most existing ring-shaped workpiece mounting platforms in factories are typically only suitable for mounting a specific type of workpiece, and the workpiece mounting dimensions are limited. Therefore, they are not suitable for mounting workpieces of different types and sizes, resulting in low versatility in welding and mounting. Thus, there is room for improvement.

The work platform 1 has an adjustment groove 11 extending along its length. The fixed bracket 2 is fixedly installed on the work platform 1, located on one side of the adjustment groove 11 along its length. The movable bracket 3 is detachably installed on the adjustment groove 11 via a connector, allowing adjustment of the distance between the movable groove and the fixed groove by moving the movable bracket 3 within the adjustment groove 11. The rotating component is fixed relative to the fixed bracket 2, with its rotating end penetrating the fixed bracket 2 and positioned opposite the movable bracket 3. The extension component 5 is installed on the top of the movable bracket 3, with its protruding end penetrating the movable bracket 3 and opposite the rotating component. A rotating head 51 is rotatably connected to the protruding end of the extension component 5. The welding torch clamping bracket 7 is attached to the top surface of the work platform 1 by screws. The distance between the welding torch clamping bracket 7 and the fixed bracket 2 and the movable bracket 2 is opposite. The welding torch clamping bracket 7 has several connecting holes 71 in the vertical direction. The clamping arm 72 is attached to the connecting holes 71 by screws. The user can adjust the installation height of the clamping arm according to actual needs. The end of the clamping arm 72 is used to install the welding torch.

[0024] Therefore, by setting a fixed bracket 2 and a movable bracket 3 on the work platform 1, the installation position of the movable bracket 3 can be adjusted as needed to adjust the distance between the fixed bracket 2 and the movable bracket 3, thus adapting to the installation of workpieces 8 of different types and sizes. During installation, the two ends of the workpiece 8 correspond to the rotating end of the rotating component and the protruding end of the protruding component 5, respectively. First, one end of the workpiece 8 is installed, and the other end is installed by the protruding action of the protruding component 5, thereby realizing the installation of the workpiece 8. During the welding operation, by starting the welding torch and the rotating component, while keeping the welding torch in a relatively unchanged position, the rotation speed of the rotating component is adjusted to make the workpiece 8 rotate at a specified speed, thereby realizing the gas shielded welding of the workpiece 8 using the welding torch. Compared with the prior art, this utility model can adjust the distance between the fixed bracket 2 and the movable bracket 3, thus adapting to the installation of workpieces 8 of different types and sizes, and has better versatility.

[0027] In this embodiment, the rotating component includes a motor housing 4 and a drive motor 41 (the drive motor 41 is a variable frequency motor, which can realize the rotational movement of the workpiece). The motor housing 4 is installed on one side of the fixed bracket 2. The drive motor 41 is attached to the motor housing 4 by screws. The rotating end of the drive motor 41 extends out of the motor housing 4 towards the fixed bracket 2. The fixed bracket 2 is rotatably connected to a rotor 42. The rotor 42 passes through the fixed bracket 2 and corresponds to the rotating head 51. The rotating end of the drive motor 41 is connected to the rotor 42 to drive the rotor 42 to rotate, thereby realizing the function of driving the installed workpiece 8 to rotate at a specified speed.

[0028] In this embodiment, an electrical control box 6 is provided on the top surface of the motor housing 4. The electrical control box 6 contains a PLC programmable controller and a power supply. The drive motor 41 is electrically connected to the programmable controller, and the power supply provides power to the PLC programmable controller and the drive motor 41.

[0029] The PLC programmable controller has a timer. A laser sensor switch 43 is provided on the side of the motor housing 4.
