Description

Mobile welding device Technical Field The application relates to the technical field of welding, in particular to a mobile welding device. Background In the scene outside large-scale work piece or fixed production line, remove welding set because of its flexible removal to the operation position that can carry welding system to promote welding operation's mobility and application scope. In the related art, a typical mobile welding device is provided with a rigid gantry frame, on which a girder movable in the X-axis direction is mounted transversely, and on which a welding gun slidable in the Y-axis direction is mounted. The workpiece is placed and fixed on a central platform of a working area of the equipment in advance, the platform is a cast iron flat plate with grid-shaped positioning holes, and the mechanical rigid fixation of the workpiece is realized through a clamp However, existing mobile welding devices still suffer from the disadvantage that the entire welding process flow relies on the workpiece being pre-accurately and fixedly mounted on the central platform. Once the workpiece has a deviation due to a change in dimensional specification or initial placement position, cumbersome positioning, clamping and track programming work must be performed again. In the welding process, the workpiece is completely in a passive state, and the pose of the workpiece cannot be dynamically adjusted according to the requirement of a welding path. When facing a workpiece having a complex space curve weld or requiring multi-angle welding, the path of movement of the welding gun becomes extremely complex, sometimes even requiring the gun to reach certain positions in a difficult-to-achieve pose, while the workpiece cannot be rotated in concert to provide a better, more convenient orientation for welding, affecting the efficiency of the welding process. Disclosure of Invention The embodiment of the application provides a mobile welding device, which solves the problem that the welding efficiency is affected when the size of a workpiece to be replaced or the initial placement position deviate due to the fact that the workpiece is rigidly fixed. The embodiment of the application adopts the following technical scheme: In a first aspect, an embodiment of the present application provides a mobile welding device, including a frame, the surface of the frame is provided with a positioning slide rail, the positioning slide rail is slidably connected with a positioning table through a positioning slide block, one side of the positioning slide rail is provided with a first drive, the first drive is connected with the positioning slide block through a ball screw, a second drive is arranged in the positioning slide block, an output shaft of the second drive is fixedly connected with the positioning table so as to drive the positioning table to rotate, a limiting ring is arranged on the positioning table, the limiting ring is matched with a shape of a workpiece to be welded, one side of the frame is provided with a welding slide rail, the welding slide rail is arranged along the length direction of the frame, the welding slide rail is slidably connected with two welding frames through the welding slide block, two sides of the welding slide rail are provided with a third drive, an output shaft of the third drive is connected with the welding frame through the ball screw, a welding head is arranged on the welding frame, an infrared camera is arranged on the welding frame, and the frame is provided with a central controller, and the central controller can receive image data of the infrared camera so as to adjust positions of the welding frame and the welding head. By adopting the technical scheme, the first drive is matched with the ball screw, and the positioning table is driven to accurately translate along the positioning slide rail, so that the limitation that a workpiece can be fixed only at a single point is solved, and different sections of a welding line are allowed to be sequentially moved to an optimal welding station. The second drive directly drives the positioning table to rotate, so that circular seams of round workpieces or complex workpieces needing multi-angle welding can be matched with a welding gun through rotation of the workpieces, and complex space curve welding seams are converted into relatively simple relative movement, so that welding accessibility is greatly improved. The limiting ring is customized according to the shape of the workpiece, quick initial positioning and circumferential limiting are provided, and workpiece clamping adjustment time is shortened. Meanwhile, the welding frame is moved on an independent welding slide rail by the third driving control, the central controller can cooperatively control the movement/rotation of the positioning table and the movement of the welding frame in combination with the identification of the infrared camera to the welding seam or the workpiece characteristics
