Description

Technical Field

[0001] The utility model relates to the technical field of gantry arc welding machines, in particular to a gantry automatic submerged arc welding machine which can prevent weldment deformation. Background Art

[0002] Gantry automatic submerged arc welding machines are divided into two types: bridge type and gantry type. The bridge type welding manipulator consists of a beam and two supporting and walking trolleys. The welding head can move horizontally along the beam, and the trolley can move longitudinally along the track; the gantry type welding manipulator has one more gantry than the bridge type. The welding head can move horizontally on the gantry beam, or on a separate beam that can be raised and lowered along the gate column. The latter can be used for welding structures of different heights; the bridge type welding manipulator is suitable for large-area flat plate splicing or hull plate frame structure welding. However, the existing gantry automatic submerged arc welding machines have some shortcomings, such as:

[0003] Publication number: CN203156206U A gantry automatic submerged arc welding machine capable of preventing weldment deformation, the device applies pressure pulses to the weldment by hammering the weldment after welding, thereby eliminating welding stress and avoiding weldment deformation. Therefore, when the gantry automatic submerged arc welding machine capable of preventing weldment deformation is used to weld the weldment, there is no need to correct the weldment, which simplifies the production process, reduces the production difficulty, reduces the production cost, and effectively ensures the production quality. However, in actual use, since it is difficult to adjust the position of the welding machine, it may cause the workpiece to need manual fine-tuning during the welding process, thereby reducing the use efficiency of the equipment.

[0004] Therefore, we propose a gantry automatic submerged arc welding machine that can prevent weldment deformation, so as to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide a gantry automatic submerged arc welding machine which can prevent weldments from being deformed, so as to solve the problem raised in the above background technology that most of the existing gantry automatic submerged arc welding machines are difficult to adjust the position of the welding machine, which may cause the workpiece to need manual fine-tuning during the welding process, thereby reducing the use efficiency of the equipment.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gantry automatic submerged arc welding machine capable of preventing weldment deformation, comprising a gantry, an operating table connected to the bottom of the gantry, a first motor is provided on the inner side of the top of the gantry, and the first motor is connected to a first gear, and the first gear is meshed with a crawler, and the crawler is meshed with a second gear, and two groups of first screw rods are provided inside the gantry, and the bottoms of the first gear and the second gear are connected to the first screw rod, the first screw rod is threadedly connected to the first screw rod, and the first screw rod is connected to an extension frame;

[0008] Since the first motor can drive the first lead screw to rotate, the first lead screw can drive the first lead screw to rise and fall, and then the second motor drives the second lead screw to rotate, so that the second lead screw can drive the second lead screw to rotate, so that the position of the electric welding machine body can be fine-tuned, thereby increasing the adjustability of the equipment during the welding process, and through the setting of the anti-deformation mechanism, the impact of welding stress on the workpiece can be reduced during the welding process.

[0010] The above technical solution enables the workpiece to be fixed on the fixing seat again and can be fixed by the fixing bar, so that a certain pressure is formed on the top of the workpiece. During the welding process, the fixing seat and the fixing bar form an extrusion pressure on the workpiece, which acts as a rigid fixation and can prevent the workpiece from shifting, thereby offsetting the welding stress.

[0011] As a preferred technical solution of the utility model, the anti-deformation mechanism includes a splash-proof seat, and a group of telescopic rods are respectively provided on the left and right sides inside the splash-proof seat, and the telescopic rods and the fixed wedges form a snap-on connection.

[0012] The above technical solution enables the anti-deformation mechanism to fix workpieces of different sizes by using different fixed wedges and adjusting the position of the fixed wedges through the telescopic rod to fix the workpiece, thereby reducing the influence of welding stress on the workpiece.

[0013] As a preferred technical solution of the utility model, a fixing frame is provided on the right side of the top of the gantry, and the gantry is connected to the second gear through the fixing frame.

[0014] The adoption of the above technical solution can make the gantry more stable when connected to the second gear, thereby increasing the firmness of the equipment during operation.

[0015] As a preferred technical solution of the utility model, an empty slot is provided inside the left and right sides of the gantry, and the gantry is connected to the first screw rod through the empty slot.

[0016] The adoption of the above technical solution enables the gantry to be installed through the reserved empty slot when installing the first screw rod, thereby increasing the portability of the device in the assembly type.

[0017] As a preferred technical solution of the utility model, a connector is provided at the bottom of the second lead screw, and the second lead screw is connected to the welding machine body through the connector.

[0018] The adoption of the above technical solution can make it more convenient to connect or disassemble the second lead screw with the welding machine body, thereby increasing the disassembly capability of the device.

[0019] As a preferred technical solution of the present utility model, the top of the operating table is fixedly connected to the gantry, and the operating table is fixedly connected to the anti-deformation mechanism.

[0020] The adoption of the above technical solution can make the operating table more stable when connected to the anti-deformation mechanism or the gantry, thereby increasing the firmness of the equipment.

[0021] Compared with the prior art, the utility model has the following beneficial effects: since the first motor can drive the first screw rod to rotate, the first screw rod can drive the first screw rod to lift, and then the second motor drives the second screw rod to rotate, so that the second screw rod can drive the second screw rod to rotate, so that the position of the electric welding machine body can be fine-tuned, the adjustability of the equipment during the welding process is increased, and the anti-deformation mechanism is set, so that the workpiece can be welded in the process, and the influence of welding stress on the workpiece can be reduced. The specific contents are as follows:

[0022] 1. Through the setting of the fixing seat and the fixing bar, when the workpiece is fixed on the fixing seat, it can be fixed by the fixing bar, so that a certain pressure is formed on the top of the workpiece. During the welding process, the fixing seat and the fixing bar form an extrusion pressure on the workpiece, so as to act as a rigid fixation, which can prevent the workpiece from deflecting, thereby offsetting the welding stress;

[0023] 2. Through the setting of the telescopic rod and the fixed wedge block, the anti-deformation mechanism can fix the workpieces of different sizes through different fixed wedge blocks and by adjusting the position of the fixed wedge block through the telescopic rod, thereby reducing the influence of welding stress on the workpiece;

[0024] Furthermore, by providing a connector at the bottom of the second lead screw, the second lead screw can be more conveniently connected to or disassembled from the welding machine body, thereby increasing the disassembly capability of the device. BRIEF DESCRIPTION OF THE DRAWINGS
