Description

[0001] WELDING ASSEMBLY

[0002] TECHNICAL FIELD

[0003] The invention relates to a welding assembly comprising at least one table for placing the workpiece thereon, at least one bridge extending in the direction of a first axis in the upper neighboring part of said table and at least partially movable in the direction of a second axis, and at least one welding unit connected to said bridge so as to be at least partially displaced in said first axis and allowing welding to be performed on the workpiece.

[0004] PRIOR ART

[0005] Gas metal arc welding is a welding method used to join metal parts. In this method, the welding process is carried out in a gas atmosphere. The gas atmosphere can often contain inert gases such as argon, helium or carbon dioxide. It is preferred in industrial applications that require high precision and quality. Welding assemblies that perform said gas metal arc welding are often designed to handle complex structures where multiple parts need to be joined. Such structures are used in industrial applications, especially in large-scale production processes and special projects.

[0006] Application No. CN112605579A known in the literature addresses a numerical controlled welding machine with multiple transpositions. Said welding machine consists of a welding support, a workbench fixedly mounted on the welding support, stand columns fixedly mounted on both sides of the workbench, and a cross beam mounted fixedly on the outer surfaces of the upper ends. Rotating the welding gun 90 degrees and obtaining a five-axis structure are mentioned. In addition to not being used in the gas metal arc welding process, the relevant document does not mention the movement of the welding unit in two different axes. For this reason, the desired precision and efficiency cannot be achieved while welding workpieces with different geometries.

[0007] Due to the complex geometry of the part to be welded, the welding process cannot be achieved with the desired efficiency in the welding assemblies of the present art. Due to the movement sensitivity, control system problems, difficult working conditions encountered in the welding process, it is not possible to operate on many axes. The inability to weld on more axes with the movement of the welding unit reduces the welding efficiency in the workpieces and increases the workmanship. The desired welding process is forced to be subjected to more than one operation.

[0008] As a result, all the above-mentioned problems have made it imperative to make an innovation in the relevant technical field.

[0009] SUMMARY OF THE INVENTION

[0010] The present invention relates to a welding assembly to eliminate the above-mentioned disadvantages and bring the new advantages to the relevant technical field.

[0011] An object of the invention is to introduce a controllable welding assembly capable of welding with precision.

[0012] Another object of the invention is to introduce a welding assembly capable of quickly and efficiently welding multiple parts.

[0013] In order to accomplish all the objects mentioned above and which will arise from the detailed description below, the present invention is a welding assembly comprising at least one table for placing the workpiece thereon, at least one bridge extending in the direction of a first axis in the upper neighboring part of said table and at least partially movable in the direction of a second axis, and at least one welding unit connected to said bridge so as to be at least partially displaced in said first axis and allowing welding to be performed on the workpiece. Accordingly, its novelty is that said welding unit comprises at least a first body part and at least a second body part, comprises at least one welding end on said second body part to perform the welding process in the welding unit, and that the first body part is configured to move at least partially linear in a third axis in order to be brought towards and further away from the table, the second body part has at least partial freedom of rotation about a fourth axis on the first body part, and said welding end has at least partial freedom of rotation on a fifth axis perpendicular to the fourth axis on the second body part. Thus, a welding assembly is obtained in which the welding process is carried out precisely in more than one axis. A possible embodiment of the invention is characterized in that it comprises at least a first drive element, to which the second body part is connected so that it has at least partial freedom of rotation on the fourth axis. Thus, it allows the welding end to perform the welding process in the desired form on a different axis.

[0014] Another possible embodiment of the invention is characterized in that it comprises a belt pulley mechanism between said first drive element and the second body part. Thus, there is no problem in the movement transfer required for the welding assembly to perform welding on the fourth axis.

[0015] Another possible embodiment of the invention is characterized in that it comprises at least a second drive element, to which the welding end is connected so that it has at least partial freedom of rotation on the fifth axis. Thus, it is possible to perform welding on one more axis.

[0016] Another possible embodiment of the invention is characterized in that it comprises a belt pulley mechanism between said second drive element and the welding end. Thus, there is no problem in the movement transfer required for the welding assembly to perform welding on the fifth axis.

[0017] Another possible embodiment of the invention is characterized in that it comprises at least one bearing wall between the first body part and the bridge. Thus, the bridge is connected to the welding unit.

[0018] Another possible embodiment of the invention is characterized in that the bridge is configured such that it is at least partially displaced in the extension direction of the table. Thus, multiple workpieces can be welded easily and quickly on five axes.

[0019] Another possible embodiment of the invention is characterized in that the welding end is configured to perform gas metal arc welding. Therefore, the welding assembly in which the metal parts are welded precisely and in the desired form is provided.

[0020] BRIEF DESCRIPTION OF THE DRAWING

[0021] Fig. 1 shows a representative perspective view of the welding assembly of the invention. Fig. 2 shows a representative perspective view of the welding unit in the welding assembly of the invention.

[0022] DETAILED DESCRIPTION OF THE INVENTION

[0023] In this detailed description, the subject of the invention is explained by way of example only for a better understanding of the subject, which shall not create any limiting effect.

[0024] Fig. 1 shows a representative perspective view of the welding assembly (10) of the invention. Accordingly, said assembly of the invention describes a configuration in which gas metal arc welding process of more than one workpiece (60) is provided. In order to join metal parts, the welding process is carried out in a gas atmosphere. For this reason, the welding process performed in the welding assembly (10) can be performed on multiple workpieces (60) with complex geometry simultaneously and with the desired efficiency.

[0025] The welding assembly (10) of the invention comprises at least one table (20). Multiple workpieces (60) are welded simultaneously on said table (20). There is at least one bridge (30) located on the table (20). Said bridge (30) allows the welding assembly (10) to move during the welding process. With the bridge (30) located on the table (20), a large volume of movement is provided. The bridge (30) extends on the table (20) in the direction of at least one first axis (I) and can move in the direction of at least a second axis (II). In this way, the welding assembly (10) does not experience movement restrictions when welding more than one part.

[0026] The welding assembly (10) comprises at least one welding unit (30) located on the bridge (40). Said welding unit (40) is the portion where the welding process is carried out. Fig. 2 shows a representative perspective view of the welding unit (40). As can be seen here, the welding unit (40) comprises at least a first body part (41 ). Said first body part (41 ) is capable of partially linear movement on at least a third axis (III). In this way, the first body part (41 ) moves towards and further away from the table (20). In a possible embodiment of the invention, the welding assembly (10) comprises at least one bearing wall (50). Said bearing wall (50) connects the welding unit (40) with the bridge (30). In this way, movement on the third axis (III) is achieved while the welding process is carried out. The welding unit (40) comprises at least a second body part (43) located below the first body part (41 ). Said second body part (43) provides flexibility of movement for the welding process. The welding (10) assembly comprises at least a first drive element (42). Accordingly, said first drive element (42) ensures that the second body part (43) partially rotates on at least a fourth axis (IV). In a possible embodiment of the invention, the first drive element (42) rotates the second body part (43) by means of a belt pulley mechanism. In this way, it allows the movement transfer to be done in an easy and controllable way. The rotational movement of the second body part (43) on the fourth axis (IV) is the fourth axis (IV) on which the welding assembly (10) can carry out the welding process.

[0027] The welding unit (40) comprises at least one welding end (45) located on the second body part (43). Said welding end (45) is the portion where the welding assembly (10) comes into contact with the workpiece (60) for the gas metal arc welding process. From here, gas metal arc welding can be performed on the workpiece (60) in the desired form. There is at least a fifth axis (V) on which the welding end (45) is partially rotated perpendicular to the fourth axis (IV). With said fifth axis (V), the welding end (45) can make a partial rotational movement, and thus the fifth axis (V) where welding can be performed on the workpiece (60) is obtained. The welding assembly (10) comprises at least a second drive element (44) for the rotational movement of the welding end (45). A belt pulley mechanism is located between the second drive element (44) and the welding end (45). Therefore, the second drive element (44) is able to transmit the rotational movement to the welding end (45) in a comfortable and controllable manner.

[0028] In line with all of the described, the invention works as follows; there is a table (20) on which workpieces (60) are positioned to perform the gas metal arc welding process. A bridge (30) that can move on the first axis (I) and the second axis (II) is located in the upper neighboring part of the table (20). The welding unit (40) connected to the bridge (30) consists of the first body part (41 ) and the second body part (43) positioned successively. The first body part (41 ) makes a linear movement on the third axis (III) in order to move towards and further away from the workpiece (60). In order to ensure this movement, the welding unit (40) and the bridge (30) are connected to each other by means of the bearing wall (50). In addition, the first body part (41 ) partially rotates on the fourth axis (IV) with the drive it receives from the first drive element (42) via the belt pulley mechanism. On the second body part (43) located below the first body part (41), there is a welding end (45) where the welding process is carried out. The welding end (45) can partially rotate on the fifth axis (V) positioned perpendicularly to the fourth axis (IV), driven by a belt pulley mechanism from the second drive element (44). In this way, a welding assembly (10) that can weld precisely in five axes is provided.

[0029] Therefore, a large number of workpieces (60) with complex geometry placed on the welding assembly (10) are precisely welded with gas metal arc process. In order to enable this, in addition to the movement of the bridge (30) in three axes, the welding unit (40) makes a rotational movement in two more axes. With the interconnected structure of the first body part (41 ) and the second body part (43) of the welding unit (40), rotational movement is additionally provided in two axes. As a result, a welding assembly (10) with a large volume of working potential, high welding process efficiency and five-axis operation is obtained.

[0030] The scope of protection of the invention is specified in the appended claims and cannot be limited to what is described for illustrative purposes in this detailed description. It is clear that a person skilled in the art can produce similar embodiments in the light of what is explained above, without deviating from the main theme of the invention.
