Description

Technical Field

[0001] This utility model relates to the field of submerged arc welding machine technology, specifically an automatic submerged arc welding machine that can prevent the deformation of welded parts. Background Technology

[0002] Utility model patent CN222221410U discloses a gantry automatic submerged arc welding machine that can prevent deformation of welded parts. It includes a gantry frame and an operating platform connected to the bottom of the gantry frame. A first motor is located on the inner side of the top of the gantry frame and is connected to a first gear. The first gear meshes with a track, which meshes with a second gear. Two sets of first lead screws are located inside the gantry frame, and the bottoms of the first and second gears are connected to the first lead screws. The first lead screws and a first lead bar form a threaded connection, and the first lead bar is connected to an extension frame. A second motor is located inside the extension frame and is connected to a second lead bar. The second lead screw and the second lead bar form a threaded connection, and the second lead bar is connected to the welding machine body. An operating platform is located at the bottom of the gantry frame, and an anti-deformation mechanism is located on the top of the operating platform. Because the first motor drives the first lead screw to rotate, the first lead screw can drive the first lead bar to rise and fall. Subsequently, the second motor drives the second lead screw to rotate, which in turn drives the second lead bar to rotate. This allows for fine-tuning of the welding machine body's position, increasing the adjustability of the equipment during the welding process. Furthermore, the anti-deformation mechanism reduces the impact of welding stress on the workpiece during welding. The anti-deformation mechanism includes a fixed base, with a rotating shaft on the top left side of the fixed base. The rotating shaft is rotatably connected to a fixing bar, and the right side of the fixing bar is connected to a fixing buckle, which is connected to the fixed base.

[0003] The above-mentioned patents have the following shortcomings:

[0004] The workpiece is rigidly fixed by the pressure exerted by the fixing seat and fixing strip to prevent displacement, thereby offsetting the welding stress. However, the workpiece and the fixing strip are in rigid contact and compression, making the workpiece prone to damage. Utility Model Content

[0005] In view of the problems existing in the current automatic submerged arc welding machine that can prevent the deformation of welded parts, this utility model is proposed.

[0006] Therefore, the purpose of this invention is to provide an automatic submerged arc welding machine that can prevent deformation of weldments, solving the problem in the aforementioned patents where the workpiece is subjected to pressure by a fixed seat and a fixing bar for rigid fixation to prevent displacement and thus offset welding stress. However, this results in rigid contact and pressure between the workpiece and the fixing bar, making the workpiece prone to damage.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0008] An automatic submerged arc welding machine that can prevent deformation of welded parts includes a bracket, on which a U-shaped support seat and a welding mechanism are mounted. The welding mechanism is located above the U-shaped support seat. A spring is mounted on the U-shaped support seat, and a carrier plate is mounted on the top of the spring. The two ends of the carrier plate are slidably connected to the U-shaped support seat. A clamping and fixing component is mounted on the carrier plate.

[0009] As a preferred embodiment of the automatic submerged arc welding machine that can prevent deformation of welded parts according to the present invention, the spring is provided with a first mating plate and a second mating plate welded to its top and bottom ends, respectively. The first mating plate is connected to the carrier plate by bolts, and the second mating plate is connected to the U-shaped support seat by bolts.

[0010] As a preferred embodiment of the automatic submerged arc welding machine that can prevent deformation of welded parts according to the present invention, wherein: both ends of the carrier plate are welded with first sliders, both ends of the U-shaped support are provided with first grooves, and the inner wall of the first groove is slidably connected to the first slider.

[0011] As a preferred embodiment of the automatic submerged arc welding machine that can prevent deformation of welded parts according to the present invention, the clamping and fixing assembly includes an L-shaped support plate that is slidably connected to a carrier plate, a threaded rod is threadedly connected to the L-shaped support plate, and a clamping plate is welded to the bottom of the threaded rod.

[0012] As a preferred embodiment of the automatic submerged arc welding machine that can prevent deformation of welded parts according to the present invention, wherein: a second sliding groove is provided on the top of the carrier plate, a second slider is welded to the bottom of the L-shaped support plate, and the second slider is slidably connected to the inner wall of the second sliding groove.

[0013] As a preferred embodiment of the automatic submerged arc welding machine for preventing deformation of welded parts according to this utility model, the welding mechanism includes a housing mounted on a bracket, a servo motor mounted at the end of the housing, a lead screw connected to the output shaft of the servo motor via a coupling, a moving block threadedly connected to the lead screw, an electric push rod mounted at the bottom of the moving block, a submerged arc welding machine support frame mounted at the bottom of the electric push rod, and a submerged arc welding machine mounted on the submerged arc welding machine support frame.

[0014] Compared with existing technologies:

[0015] 1. By setting a spring at the bottom of the carrier plate, since the spring is an elastic component, the carrier plate and the submerged arc welding machine can elastically clamp the workpiece, thereby achieving soft welding of the workpiece and avoiding the workpiece being squeezed and deformed, thus achieving the purpose of protecting the workpiece during welding.

[0016] 2. By setting up a welding mechanism, the lead screw is driven to rotate by starting a servo motor, which in turn drives the moving block to move, thereby realizing the movement of the submerged arc welding machine. This allows for welding at different positions on the workpiece, making welding more flexible. Attached Figure Description
