[0002] The application of welding trolley is a method of efficient welding in modern shipbuilding.

[0003] For welding of magnetic metal plates, such as steel plates, an electromagnet is usually set on the rail of the welding trolley, and a medium-frequency magnet is used to adsorb and fix the plate on the rail, and the plate is magnetically adsorbed and fixed by magnetism.

[0004] When welding non-magnetic metal plates, such as aluminum alloy plates, it is impossible to fix the plates with magnets. Usually, a vacuum suction cup is set on the rail of the welding trolley, and the vacuum suction cup is used to adsorb and fix the plates on the rail. The plate is vacuum adsorbed and fixed using the principle of air pressure.

For non-magnetic metal plates with matte surface, vacuum adsorption cannot be used for fixation. The plates can only be clamped with ordinary clamps. The application range of vacuum adsorption is narrow. In addition, there is a lot of dust in the construction environment, and it is difficult to thoroughly clean the surface of the vacuum suction cup and the plate, which affects the adsorption stability of the vacuum suction cup on the plate.

[0036] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0037] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] like Figures 1 to 5 As shown, a non-magnetic metal sheet welding device provided by the present invention includes a rail 1, a fixing component and a connecting component, wherein a welding trolley is slidably arranged on the rail 1; the fixing component is arranged on the rail 1, and the fixing component includes a first connecting plate 2, the first connecting plate 2 has a first side surface 21 and a second side surface 22 which are parallel, the first side surface 21 is used to fit with the surface of the sheet 100 to be welded, the first side surface 21 is provided with a mounting hole 23, and the mounting hole 23 passes through the second side surface 22; the connecting component includes a connecting stud 5 and a connecting nut 6, the connecting stud 5 has a first end 51 and a second end 52, the first end 51 is used to be welded with the sheet 100 to be welded, and the second end 52 passes through the mounting hole 23 and is screwed with the connecting nut 6.

[0039] By setting the mounting hole 23 and the connecting assembly, the plate 100 to be welded is fixed to the rail 1 by means of studs and nuts, that is, the plate 100 to be welded and the rail 1 are connected together by threaded connection. The connection structure is simple and the connection stability is high, and the plate 100 to be welded and the rail 1 can be effectively fixed. The connecting stud 5 and the plate 100 to be welded are fixed by stud welding. Compared with the vacuum adsorption requirements in the prior art, the cleanliness, flatness and smoothness of the surface of the plate 100 to be welded by stud welding are lower, and therefore, the scope of application is wider.

[0040] In this embodiment, the connection stud 5 and the plate 100 to be welded are fixed by stud welding. Specifically, the welding depth between the first end 51 of the connection stud 5 and the plate 100 to be welded is not greater than 0.5 mm. By setting the welding depth between the first end 51 of the connection stud 5 and the plate 100 to be welded to be not greater than 0.5 mm, the damage range of the plate 100 to be welded can be reduced, the strength impact of the plate 100 to be welded can be reduced, and it is convenient to grind the plate 100 to be welded after removing the connection stud 5.

[0041] Preferably, the material of the connecting stud 5 is the same as the material of the plate 100 to be welded. By setting the material of the connecting stud 5 to be the same as the material of the plate 100 to be welded, even if part of the connecting stud 5 remains on the plate 100 to be welded after the connecting stud 5 is removed, the remaining part of the connecting stud 5 can be directly removed by grinding, and the strength of the plate 100 to be welded will not be affected by the material problem. In this embodiment, the plate 100 to be welded is an aluminum plate, the connecting stud 5 is an aluminum stud, and the diameter of the connecting stud 5 is 10 mm and the length is 25 mm.

[0042] Furthermore, at least two fixing components are provided, and a connecting component is provided corresponding to each fixing component. All the fixing components are arranged at intervals along the length direction of the rail 1, and the length of the mounting hole 23 extends along the length direction of the rail 1. By providing multiple fixing components, the connection points between the plate 100 to be welded and the rail 1 can be increased, and the connection points are dispersed, and the plate 100 to be welded and the rail 1 are connected in a multi-point positioning manner to avoid displacement of the plate 100 to be welded and the rail 1 during the welding process of the welding carriage; it can be understood that the positioning between the connecting stud 5 and the plate 100 to be welded may be offset, resulting in a part of the connecting stud 5 being unable to align with the center of the mounting hole 23. The length of the mounting hole 23 is set to extend along the length direction of the rail 1, and the position error between the connecting stud 5 and the plate 100 to be welded can be absorbed by adjusting the position of the connecting stud 5 in the mounting hole 23.

[0043] Furthermore, one end of the mounting hole 23 extends to connect with the peripheral side surface of the first connecting plate 2, that is, the mounting hole 23 is in a notch shape. By setting one end of the mounting hole 23 to extend to connect with the peripheral side surface of the first connecting plate 2, the connecting stud 5 can be inserted into the mounting hole 23 from the axial direction of the mounting hole 23, and can also be inserted into the mounting hole 23 from the radial direction of the mounting hole 23, thereby reducing the difficulty of connecting the connecting component and the fixing component.

[0044] Specifically, each first connecting plate 2 is provided with a plurality of mounting holes 23, and the mounting holes 23 are arranged at intervals along the width direction of the rail 1. The non-magnetic metal sheet welding device of this embodiment is applied to the field of ships. It can be understood that the size of the plate 100 to be welded is relatively large, and increasing the number of fixing components can disperse the force of the plate 100 to be welded in the length direction of the rail 1, and increasing the mounting holes 23 can disperse the force of the plate 100 to be welded in the width direction of the rail 1, and also increase the connection points between the plate 100 to be welded and the first connecting plate 2, thereby improving the stability of the connection. In this embodiment, three mounting holes 23 are provided on each first connecting plate 2, and the three mounting holes 23 have the same size. Two connecting studs 5 are provided corresponding to each first connecting plate 2, and the two connecting studs 5 are selectively inserted into the corresponding mounting holes 23 of the same first connecting plate 2 according to the on-site conditions.

[0045] Furthermore, the fixing assembly further includes a position regulator 4 and a second connecting plate 3, the first connecting plate 2 is movably connected to the second connecting plate 3 through the position regulator 4, the second connecting plate 3 is fixed to the rail 1, and the position regulator 4 is used to adjust the position of the first connecting plate 2 along the width direction of the rail 1. By providing the position regulator 4, the position of the first connecting plate 2 can be adjusted in the width direction of the rail 1, thereby absorbing the position error of the connecting stud 5 and the plate 100 to be welded in the width direction of the rail 1.

[0046] Specifically, the position regulator 4 includes a base 41, a screw rod 42 and a slider 44. The screw rod 42 is rotatably arranged on the base 41 through a bearing. A slide rail 43 is arranged on the base 41. The slider 44 is slidably arranged on the slide rail 43, and the slider 44 is threadedly connected to the screw rod 42. The first connecting plate 2 is fixed on the slider 44. The lengths of the slide rail 43 and the screw rod 42 both extend along the width direction of the rail 1. When the screw rod 42 is rotated, under the restriction of the slide rail 43, the slider 44 converts the rotation of the screw rod 42 into a linear movement along the length direction of the slide rail 43, thereby driving the first connecting plate 2 to move. In this embodiment, the slide rail 44 is a groove structure arranged on the base 41.

[0047] In this embodiment, the second connecting plate 3 includes a first plate body 31 and a second plate body 32 vertically connected, wherein the first plate body 31 is connected to the rail 1, the second plate body 32 and the first plate body 31 are connected by threads, the base 41 of the position regulator 4 is connected to the second plate body 32 by threads, and the slider 44 and the first connecting plate 2 are connected by threads.

[0048] The connecting nut 6 is a ring nut, which makes it convenient to directly apply force to the connecting nut 6 and facilitate adjustment.

[0049] Furthermore, the first side surface 21 of the first connecting plate 2 faces upward, and the second side surface 22 faces downward. At this time, the first side surface 21 can provide support for the plate 100 to be welded, increase the contact area between the first connecting plate 2 and the plate 100 to be welded, and reduce stress concentration.

[0050] This embodiment also provides a non-magnetic metal sheet welding method, using the non-magnetic metal sheet welding device in any of the above embodiments, including the following steps:

[0051] Step 100, welding the first end 51 of the connecting stud 5 to the surface of the plate 100 to be welded;

[0052] Step 200, pass the second end 52 of the connecting stud 5 through the mounting hole 23 of the first connecting plate 2, screw the connecting nut 6 into the second end 52, and fix the plate 100 to be welded to the fixing assembly;

[0053] Step 300, welding the plate 100 to be welded using a welding carriage;

[0054] Step 400, twist and separate the connecting nut 6 and the connecting stud 5 to separate the plate 100 to be welded from the fixing assembly;

[0055] Step 500: Separate the connecting stud 5 from the plate 100 to be welded.

[0056] The plate 100 to be welded is fixed to the rail 1 by means of studs and nuts, that is, the plate 100 to be welded and the rail 1 are connected together by threaded connection. The connection structure is simple, the operation is convenient, and the connection stability is high. The plate 100 to be welded and the rail 1 can be effectively fixed. The connecting studs 5 and the plate 100 to be welded are fixed by stud welding. Compared with the vacuum adsorption requirements in the prior art, the cleanliness, flatness and smoothness of the surface of the plate 100 to be welded by stud welding are lower, and the fixing difficulty is small.

[0057] In this embodiment, the connecting stud 5 is separated from the plate 100 to be welded by knocking the second end 52 of the connecting stud 5 along the radial direction of the connecting stud 5. By knocking the second end 52 of the connecting stud 5 to separate the connecting stud 5 from the plate 100 to be welded, the connecting stud 5 and the plate 100 to be welded can be quickly separated; it can be understood that the product of the force and the lever arm is the moment of the force on the rotation axis, and the second end 52 of the connecting stud 5 is knocked along the radial direction of the connecting stud 5. This force will drive the connecting stud 5 to rotate around the first end 51, but the first end 51 and the plate 100 to be welded are fixed, and the first end 51 of the connecting stud 5 will be subjected to a momentary force, and this force is large, which can completely separate the connecting stud 5 from the plate 100 to be welded.

[0058] Of course, after the connection studs 5 and the plate 100 to be welded are separated, the surface of the plate 100 to be welded may be polished to improve the appearance of the plate 100 to be welded.

[0059] The non-magnetic metal plate welding device and welding method provided in this embodiment can effectively fix the plate 100 to be welded to the rail 1, solving the construction difficulties of horizontal welding, vertical welding and overhead welding of non-magnetic metal plates (for example, aluminum plates).
