[0002] The welding process is related to factors such as welding methods. The operation needs to be determined according to the material, brand, chemical composition, weldment structure type, and welding performance requirements of the workpiece to be welded. First, the welding method must be determined, such as manual arc welding, submerged arc welding, tungsten inert gas arc welding, metal arc gas shielded welding, etc. There are many types of welding methods, which can only be selected according to specific circumstances. After determining the welding method, the welding process parameters are formulated. The types of welding process parameters are different. For example, manual arc welding mainly includes: electrode model (or brand), diameter, current, voltage, welding power type, polarity connection method, number of welding layers, number of passes, and inspection.

[0003] When the arc welding fixture is in use, first fix the two weldments with the clamps respectively, and then move the two clamps to bring the two weldments close to each other. If one weldment needs to be welded at the center of the other weldment, it is necessary to adjust the height and position of one of the weldments after the weldments are clamped so that the two weldments can be aligned in the center after being brought close together. However, the existing welding fixture does not have an automatic positioning function, and the alignment is cumbersome and the use effect is not good. Utility Model Content

[0021] In this embodiment: the weldment is inserted into the cylinder 7, and the second threaded rod 18 is rotated. The threads on both sides of the second threaded rod 18 are in opposite directions, thereby driving the two threaded sleeves 17 to move in opposite directions. The two threaded sleeves 17 further drive the two turntables 13 to rotate in opposite directions through the L-shaped plate 16 and the hinge seat 15, and then drive the two longitudinal sliders 10 and the two transverse sliders 10 to slide relative to each other along the two first slide grooves 8 and the two second slide grooves 9 respectively through the slots 14 and the short columns 11. When the two sliders 10 in one direction clamp the weldment from that direction, the two sliders 10 and the corresponding turntables 13 that have been clamped on the weldment stop moving, and the second threaded rod 18 continues to be rotated, then the other turntable 13 continues to rotate, thereby driving the corresponding two sliders 10 to continue moving. By arranging rollers 12 on the inner wall of the slider 10, the weldment can slide on the inner wall of the slider 10 until the weldment is clamped in another direction.

[0027] In this embodiment, the thread directions of the two ends of the second threaded rod 18 are set to be opposite, so that when the second threaded rod 18 is rotated, the two rotating disks 13 are driven to move relative to or away from each other.

[0028] As a technical optimization solution of the present invention, a handle is provided at one end of each of the two second threaded rods 18 .

[0032] The working principle and use process of the utility model are as follows: when in use, first insert the weldment into the cylinder 7, then rotate the second threaded rod 18, the threads on both sides of the second threaded rod 18 are in opposite directions, thereby driving the two threaded sleeves 17 to move in opposite directions, and the two threaded sleeves 17 further drive the two turntables 13 to rotate in opposite directions through the L-shaped plate 16 and the hinge seat 15, and then drive the two longitudinal sliders 10 and the two transverse sliders 10 to slide relative to each other along the two first slide grooves 8 and the two second slide grooves 9 respectively through the slot hole 14 and the short column 11. When the two sliders 10 in one direction clamp the weldment from that direction, the two sliders 10 already clamped on the weldment and the corresponding The turntable 13 stops moving and continues to rotate the second threaded rod 18, then the other turntable 13 continues to rotate, thereby driving the corresponding two sliders 10 to continue to move. By arranging a roller 12 on the inner wall of the slider 10, the weldment can slide on the inner wall of the slider 10 until the weldment is clamped in the other direction, thereby fixing the weldment. After the other weldment is fixed in the same way, the servo motor 5 is started, and the servo motor 5 drives the two slide plates 6 to move relative to each other, thereby driving the two weldments to move relative to each other to butt the welds. By clamping the weldments by the four sliders 10 moving relative to each other in pairs, the weldment can be automatically fixed at the center of the cylinder 7, making it convenient to butt the weldments on the left and right sides.
