Description

Technical Field

[0001] The utility model relates to the technical field of large metal component welding, and particularly relates to an automatic assembly and welding tooling for large metal components. Background Technique

[0002] Large metal components refer to metal products with significant characteristics in terms of size, weight, and structural complexity. They are usually made of various metal materials, such as steel, aluminum, titanium, etc. These components play a crucial role in many fields. In the construction field, large steel beams and steel columns are important components for constructing high-rise buildings and large bridges, and they bear huge loads to ensure the structural stability of buildings and bridges. In the machinery manufacturing industry, such as the beds of large machine tools and the frames of heavy machinery, are all large metal components, providing a stable foundation and precise operation support for mechanical equipment.

[0003] In today's highly industrialized era, large metal components play a crucial role in many fields, such as aerospace, shipbuilding, bridge construction, and large machinery production. However, due to their usually huge size and heavy weight, there are many complex technical problems in the processing and operation during the welding process.

[0004] In the traditional production process, large metal components are generally transported to the resistance welding tooling by a conveyor belt for welding operations. However, during the transportation process, due to the combined influence of various factors such as the vibration of the conveyor belt, collision with other objects, and changes in the transmission speed, the metal components are extremely likely to be in an incorrect position or shift. When the metal component reaches the resistance welding tooling, if its position is inaccurate, the fixed press is very likely unable to accurately press down and hold the metal component, which will directly have a serious negative impact on the welding work.

[0005] Therefore, we propose an automatic assembly and welding tooling for large metal components. Content of the Utility Model

[0006] The purpose of the utility model is to solve the disadvantages existing in the prior art. In the traditional production process, large metal components are generally transported to the resistance welding tooling by a conveyor belt for welding operations. However, during the transportation process, due to the combined influence of various factors such as the vibration of the conveyor belt, collision with other objects, and changes in the transmission speed, the metal components are extremely likely to be in an incorrect position or shift. When the metal component reaches the resistance welding tooling, if its position is inaccurate, the fixed press is very likely unable to accurately press down and hold the metal component, which will directly have a serious negative impact on the welding work.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] An automatic welding tool for large metal components, including a conveyor belt structure. Above the conveyor belt structure, there is a mounting seat. At the top of the mounting seat, there is a relative synchronous movement structure which can perform synchronous relative movement. At the bottom of the relative synchronous movement structure, there are several limiting devices, and limiting mechanisms are fixedly connected to the outer sides of the several limiting devices.

[0009] Preferably, the relative synchronous movement structure includes two sliding seats. Two sliding grooves are provided on each of the two sliding seats. Inside the two sliding grooves, several sliding blocks are provided. A sliding mounting plate is provided between two adjacent sliding blocks.

[0010] Preferably, the relative synchronous movement structure further includes a first rotating shaft. At the top of the first rotating shaft, there is a connecting plate. At both ends of the connecting plate, second rotating shafts are installed. Connecting rods are connected to the two second rotating shafts. Third rotating shafts are provided at the centers of the tops of the two sliding mounting plates.

[0011] Preferably, on the back side wall of the sliding mounting plate near the back side, there is a fixed plate fixedly connected. A driving air rod is connected to the fixed plate, and the driving air rod can drive the sliding mounting plate to displace.

[0012] Preferably, the limiting device includes a mounting frame. Inside the mounting frame, there is a bearing seat. At the connection of the bearing seat and at the bottom of the mounting frame, there is a first rotating shaft. At the bottom of the first rotating shaft, there is a Y-shaped seat.

[0013] Preferably, a torsion spring shaft is provided on the first rotating shaft. At the bottom of the Y-shaped seat, several second rotating shafts are provided. Limiting rollers are connected to the bottoms of the several second rotating shafts.

[0014] Preferably, the limiting mechanism includes a fixed seat. A limiting seat is provided at the connection of the fixed seat. The limiting mechanism and the limiting device are used in cooperation.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] In the present utility model, first of all, the welding accuracy and quality have been greatly improved. Before entering the resistance welding tooling, the metal components are initially position-limited and aligned, which can accurately fix the metal components at the ideal welding position. This makes the connection of the welding points not only more firm but also evenly distributed, effectively eliminating welding defects caused by position deviation, such as false welding and missed welding.

[0017] Secondly, the production efficiency has been greatly improved. This structure effectively avoids problems such as the fixed press tool being unable to press down due to the incorrect position of the metal component and the need to repeatedly adjust the position, significantly reducing the pauses and waiting times during the production process, enabling the entire production process to operate more smoothly and efficiently. Taking steel structure buildings in the construction industry as an example, adopting this alignment structure can speed up the welding speed of steel beams, thereby shortening the construction period of the building.

[0018] In summary, this structure for aligning metal components before resistance welding is a major innovation and significant improvement to the welding process of large metal components, with broad application prospects and great economic value in many industrial fields, improving product quality and production efficiency while reducing costs.

[0028] Embodiment 1

[0029] As Figures 1-4 shown, the present utility model provides a technical solution: an automatic welding and assembling tooling for large metal components, including a conveyor belt structure 1. Above the conveyor belt structure 1, there is an installation seat 2. At the top of the installation seat 2, there is a relative synchronous movement structure 3 that can perform synchronous relative movement. At the bottom of the relative synchronous movement structure 3, there are several limiting devices 4. The outer sides of several limiting devices 4 are fixedly connected with limiting mechanisms 5. First of all, the welding accuracy and quality have been greatly improved. Before entering the resistance welding tooling, the initial position limit and alignment of the metal component are carried out, which can accurately fix the metal component at the ideal welding position. This makes the connection of the welding points not only more firm but also evenly distributed, effectively eliminating welding defects caused by position deviation, such as false welding and missed welding. Secondly, the production efficiency has been greatly improved. This structure effectively avoids problems such as the fixing clamp being unable to press down due to the incorrect position of the metal component and the need to repeatedly adjust the position, significantly reducing the pauses and waiting times during the production process, and enabling the entire production process to run more smoothly and efficiently. Taking the steel structure building in the construction industry as an example, adopting this alignment structure can accelerate the welding speed of steel beams, thereby shortening the construction period of the building.

[0030] In summary, the structure for aligning metal components before solder mask is a major innovation and significant improvement in the welding process of large metal components, with broad application prospects and great economic value in many industrial fields. It improves product quality and production efficiency while reducing costs.

[0031] Embodiment 2

[0032] As Figures 1-4 shown, the present utility model provides a technical solution: the relative synchronous movement structure 3 includes two sliding seats 31, two sliding grooves 32 are provided on both of the two sliding seats 31, a plurality of sliding blocks 33 are provided inside the two sliding grooves 32, and a sliding mounting plate 34 is provided between two adjacent sliding blocks 33.

[0033] The relative synchronous movement structure 3 further includes a first rotating shaft 35, a connecting plate 36 is connected to the top of the first rotating shaft 35, second rotating shafts 37 are installed at both ends of the connecting plate 36, connecting rods 38 are connected to both of the two second rotating shafts 37, and third rotating shafts 39 are provided at the centers of the tops of the two sliding mounting plates 34.

[0034] A fixing plate 310 is fixedly connected to the back wall of the sliding mounting plate 34 near the dorsal side, a driving air rod 311 is connected to the fixing plate 310, and the driving air rod 311 can drive the sliding mounting plate 34 to displace.

[0035] The limiting device 4 includes a mounting frame 41, a bearing seat 42 is provided inside the mounting frame 41, a first rotating shaft 43 is provided at the connection of the bearing seat 42 and at the bottom of the mounting frame 41, and a Y-shaped seat 44 is connected to the bottom of the first rotating shaft 43.

[0036] A torsion spring shaft 45 is provided on the first rotating shaft 43, a plurality of second rotating shafts 46 are provided at the bottom of the Y-shaped seat 44, and limiting rollers 47 are connected to the bottoms of the plurality of second rotating shafts 46.

[0037] The limiting mechanism 5 includes a fixed seat 51, a limiting seat 52 is provided at the connection of the fixed seat 51, and the limiting mechanism 5 and the limiting device 4 are used in cooperation.

[0038] The working process of the present utility model: When using an automatic assembly welding tooling for large metal components, in the first step, the large metal components need to be placed on the conveyor belt structure 1. To more intuitively show the effect of the device on large metal components, in this specification, steel plates are used to replace large metal components for description.

[0039] Given that large steel plates are heavy, they generally need to be placed on the conveyor belt structure 1 and enter the interior of the assembly welding tooling through the transmission of the conveyor belt structure 1 for welding operations. During the transmission, once the placement position of the large steel plate deviates, the device will correct it.

[0040] First, the large steel plate will arrive directly below the mounting seat 2. At this time, the large steel plate is in an inclined state. Then, the relatively synchronous moving structure 3 starts to start, and the driving gas rod 311 will push the fixed plate 310 to move, thereby driving the sliding mounting plate 34 connected thereto to be displaced. The sliding mounting plate 34 slides in the sliding groove 32 with the help of the sliding block 33, so that the sliding mounting plate 34 connected thereto can move toward the front. Since the two sliding mounting plates 34 are both provided with a third rotating shaft 39, and are interconnected and hinged with the connecting plate 36 through a connecting rod 38, when the sliding mounting plate 34 close to the back side moves toward the front, the sliding mounting plate 34 located on the front side will move toward the back side. Moreover, the driving source of the two sliding mounting plates 34 is a single driving gas rod 311, thereby realizing relative movement, and the moving distance is the same.

[0041] Secondly, several limit devices 4 are fixed at the bottom of the relatively synchronous moving structure 3. When the relatively synchronous moving structure 3 is relatively displaced, these limit devices 4 will be synchronously driven to be relatively displaced. During the displacement process, several limit devices 4 will be squeezed at the four corners of the large steel plate. During the squeezing, the Y-shaped seat 44 will simultaneously process the four corners of the large steel plate so that it can be corrected to a parallel state. In addition, in the process of correcting the limit, several limit rollers 47 will rotate through the second rotating shaft 46, thereby reducing resistance during the correction process. When the correction is completed, the first rotating shaft 43 will restore the Y-shaped seat 44 to its initial state, and it can also be limited by the limit mechanism 5 to prevent it from popping out to the outside.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
