[0002] In traditional anchor welding operations, manual operation is mainly used to complete the placement of the rib plate, and the entire welding process lacks a reliable and effective fixing device. The rib plate is affected by various factors such as the electromagnetic force generated by the welding arc, welding thermal deformation, and operator touch, resulting in displacement. The displacement of the rib plate causes the weld position to change during welding, and it is difficult to keep the welding parameters constant, resulting in a decrease in welding quality, and problems such as uneven welds, cold welds, and desoldering frequently occur, reducing the bearing capacity and stability of the anchor. Summary of the invention

[0003] To overcome the above-mentioned defects, an embodiment of the present disclosure provides an automated anchor welding device, which solves the technical problems that the related technology relies on manual operation, resulting in reduced welding quality and uneven welds, cold welds, desoldering, etc.

[0006] For example, in an automated foot welding device provided by at least one embodiment of the present disclosure, the clamping block has a guide groove, and the guide groove has a first guide section for providing a horizontal movement guide for the cleaning member, and the automated foot welding device further includes: A moving block, the moving block is horizontally movably arranged on the side wall of the clamping block, and its horizontal moving direction is parallel to the extending direction of the through slot; A connecting plate, one end of which is rotatably arranged on the moving block, and the other end of which is rotatably arranged on the cleaning member, wherein the connecting plate is configured such that after the moving block moves horizontally, the connecting plate follows the swing; A limiting portion is provided on the side wall of the moving block. The limiting portion is located at one side of the connecting plate and is used to abut against or cancel the abutment with the connecting plate to limit the swing of the connecting plate.

[0007] For example, in an automated foot welding device provided by at least one embodiment of the present disclosure, the guide groove further has a second guide section connected to the first guide section, the cleaning member is located in the second guide section or the first guide section after moving, and the width of the second guide section is configured to allow the cleaning member to be lifted and lowered; The clamping block also has a stopper located below the moving block and on the moving path of the connecting plate. The stopper faces the middle of the connecting plate and is configured to abut against the connecting plate to swing the connecting plate.

[0008] For example, in an automated foot welding device provided in at least one embodiment of the present disclosure, the clamping block has an inclined surface, the inclined surface extends obliquely along the height direction, and the inclined surface gradually moves away from the through slot from bottom to top; The guide groove is located on the inclined surface; The connecting plate is rotatably and slidably arranged on the cleaning member.

[0009] For example, in an automated anchor welding device provided by at least one embodiment of the present disclosure, the clamping block further has a clearance groove, through which the second welding section is exposed, and the clearance groove is used to provide a welding space for the second welding section.

[0010] For example, in an automated foot welding device provided in at least one embodiment of the present disclosure, there are four clamping blocks, which are used to jointly clamp the bottom plate located in the middle of the four clamping blocks after being moved; Each of the clamping blocks is correspondingly provided with two cleaning members, which are respectively located on both sides of the clamping block and are respectively used to clean the two first welding sections corresponding to a single rib plate.

[0011] For example, in at least one embodiment of the present disclosure, an automated foot welding device is provided, wherein the automated foot welding device further comprises: An air suction member, one end of which is arranged on one of the moving blocks, and the other end of which is arranged on another adjacent moving block, moves with one of the moving blocks, and synchronously drives another adjacent moving block to move synchronously; The air suction member has a plurality of air holes, and the air holes are configured to absorb welding gas; An air pump is arranged on the clamping block and is connected to the air suction member.

[0012] For example, in an automated anchor welding device provided by at least one embodiment of the present disclosure, the air holes have two groups, which are respectively located on both sides of the air suction piece and respectively face above the first welding section and the second welding section, and are respectively used to absorb welding gas from the first welding section and the second welding section.

[0013] For example, an automated anchor welding device provided in at least one embodiment of the present disclosure further includes: a rotating table, the rotating table is rotatably arranged, and its rotating axis is horizontally arranged, and the plurality of clamping blocks are movably arranged on the rotating table.

[0014] The beneficial effects of the embodiments of the present disclosure are: In the present disclosure, the guiding effect of the through groove on the rib plate enables the rib plate to maintain a stable position during welding. When welding the first welding section (the connection between the bolt and the rib plate) and the second welding section (the connection between the rib plate and the base plate), the rib plate will not shake or shift due to lack of constraints, thereby ensuring the quality of the welded joint. Compared with the traditional manual fixing of the rib plate and the base plate, the device only needs to place the base plate in a suitable position, start the clamping block moving mechanism to clamp the base plate, and then pass the rib plate through the through groove, which simplifies the operation process, reduces the labor intensity of workers, and improves work efficiency. In factories that mass-produce footings, convenient operation can achieve rapid loading and welding, significantly improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The present disclosure is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure, rather than to limit the present disclosure.

[0019] In order to simplify the drawings, only the parts related to the disclosure are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0020] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this disclosure can be understood according to specific circumstances.

[0021] In the present disclosure, unless otherwise expressly specified and limited, a first feature being “above” or “below” a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being “above”, “above”, and “above” a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0023] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0024] like Figure 1 to Figure 7 As shown, it shows an automated foot welding device disclosed in the present invention. In some examples, at least two clamping blocks 6 are movably arranged. When welding operation is required, the clamping blocks 6 are moved closer to or farther away from each other through a moving mechanism (such as a motor-driven lead screw mechanism, a cylinder drive mechanism, and other common linear motion drive methods). The solution of the present application is similar to a four-jaw chuck, and the drive method can also refer to the drive method of an existing four-jaw chuck. When the clamping blocks 6 are close to each other, the abutment portion 601 abuts against the side of the base plate 2, and multiple clamping blocks 6 work together to apply pressure to the base plate 2 from multiple directions, thereby achieving stable clamping of the base plate 2. The through slot 602 is located at one side of the abutment portion 601 and communicates with one side of the abutment portion 601. In this way, the rib plate 1 can pass through the through slot 602 and enter under the abutment portion 601. When placing the rib plate 1, the rib plate 1 is passed through the through slot 602. Since the side walls of the through slot 602 are in contact with both sides of the rib plate 1, the freedom of movement of the rib plate 1 in the horizontal direction (perpendicular to the length direction of the rib plate 1) is limited, so that during the welding process, the position of the rib plate 1 is limited within the range determined by the through slot 602, which plays an auxiliary guiding role. In traditional foundation welding, the bottom plate 2 lacks effective fixation. However, this solution uses multiple clamping blocks 6 to clamp the bottom plate 2 together, which can effectively prevent the bottom plate 2 from being displaced during the welding process due to factors such as welding stress and operation collision, ensuring the accuracy of the position of the bottom plate 2 during the welding process and providing a basic guarantee for high-quality welding. For example, in the foundation welding of large equipment, the stable fixation of the bottom plate 2 can make the relative position accuracy between the subsequent welded bolts 3 and the rib plate 1 and the bottom plate 2 higher, and the stability of the equipment after installation is better. The through slot 602 guides the rib plate 1, so that the rib plate 1 can maintain a stable position during welding. When welding the first welding section 4 (the connection between the bolt 3 and the rib plate 1) and the second welding section 5 (the connection between the rib plate 1 and the bottom plate 2), the rib plate 1 will not shake or shift due to lack of constraints, thus ensuring the quality of the welded joint. Compared with the traditional manual fixing of the rib plate 1 and the bottom plate 2, the device only needs to place the bottom plate 2 in a suitable position, start the clamping block 6 moving mechanism to clamp the bottom plate 2, and then pass the rib plate 1 through the through slot 602, which simplifies the operation process, reduces the labor intensity of workers, and improves work efficiency. In factories that mass-produce footings, convenient operation can achieve rapid loading and welding, significantly improving production efficiency.

[0025] In some examples, the cleaning member 7 is mounted on the clamping block 6 and can be lifted and lowered and moved horizontally. Its lifting direction is parallel to the moving direction of the corresponding clamping block 6, so that the cleaning member 7 can adjust the interval between the first welding section 4 and move closer to or farther away from the first welding section 4. When the cleaning member 7 moves to a suitable position on one side of the first welding section 4, its cleaning component (which can be a brush with a certain hardness) cleans the area of ​​the first welding section 4, for example, the position of 20-30mm on one side of the first welding section 4 is cleaned before and after welding, because before welding, there may be impurities such as oil, rust, moisture, and dust on the surface of the weldment. If these impurities are mixed into the weld, defects such as pores 1001, slag inclusions, and cracks will appear in the weld, reducing the mechanical properties and density of the weld. Cleaning the position of 20-30mm on one side of the first welding section 4 can effectively remove impurities, so that the metal is well fused during welding, and the quality and performance of the weld are guaranteed. And cleaning this area can make the flow of the welding molten pool smoother. If there are impurities on the weld surface, it may hinder the flow of the molten pool metal, resulting in poor weld formation, such as uneven weld width, uneven height, undercut, etc. After cleaning, the molten pool metal can spread and solidify better, forming a beautiful and uniform weld.

[0026] After welding, cleaning the area can remove impurities such as spatter and slag generated during welding, so that the weld surface and the surrounding area are clearly exposed, which is convenient for inspectors to accurately observe the appearance quality of the weld, such as whether there are defects such as pores 1001, cracks, and lack of fusion. If these defects are not discovered and handled in time, they may affect the safety and reliability of the welded structure.

[0027] In some examples, the guide groove 603 is provided on the clamping block 6, and the first guide section 604 thereof provides a guide for the horizontal movement of the cleaning member 7. This helps to improve the accuracy of the cleaning position of the cleaning member 7 on the first welding section 4 and ensure the consistency of the cleaning effect.

[0028] One end of the connecting plate 9 is rotatably arranged on the moving block 8, and the other end is rotatably arranged on the cleaning member 7. With respect to the length of the connecting plate 9, the moving block 8 can be moved to the top of the cleaning member 7. At this time, the interval between the moving block 8 and the cleaning member 7 is preferably the length of the connecting plate 9. When the moving block 8 moves horizontally, the cleaning member 7 is driven to move through the connecting plate 9. Since both ends of the connecting plate 9 are rotatably connected, in order to improve the stability of movement, a protrusion is provided on the side wall of the moving block 8. The limiting portion 801 on the side wall of the moving block 8 can limit the movement of the connecting plate 9, so that the cleaning member 7 can move stably.

[0029] In some examples, the second guide section 605 of the guide groove 603 is connected to the first guide section 604, and the cleaning member 7 can be raised and lowered through the second guide section 605. It should be noted that when the blocking portion 606 abuts against the middle of the connecting plate 9, the connecting plate 9 will swing around the connection point with the moving block 8 as the axis, and the swing will drive the cleaning member 7 to move, and the moving trajectory is an arc. Therefore, when the connecting plate 9 swings and drives the cleaning member 7 to move, the cleaning member 7 will not only change in the height direction, but also have a displacement in the horizontal direction. Therefore, the width of the second guide section 605 needs to be greater than the horizontal displacement distance of the cleaning member 7 so that the action can proceed normally.

[0030] The provision of the second guide section 605 increases the flexibility and adaptability of the movement of the cleaning member 7. It enables the cleaning member 7 to switch between different height positions, meeting the needs for cleaning welding areas at different heights in a variety of welding scenarios. Compared with the cleaning member 7 that can only move horizontally at a single height, the device with the second guide section 605 guide groove 603 can cope with more ground welding situations, further improving the welding quality and efficiency. For example, there may be a height difference between the welding positions of the rib plate 1 and the base plate 2, and the guide groove 603 and the second guide section 605 can enable the cleaning member 7 to adapt to such changes, ensuring that each welding area can be effectively cleaned. And the provision of the second guide section 605 allows the cleaning member 7 to move to the top when cleaning is not required, without blocking and affecting the normal welding process.

[0031] In some examples, the inclined surface 607 of the clamping block 6 extends obliquely in the height direction and gradually moves away from the through groove 602 from bottom to top. The guide groove 603 is arranged on the inclined inclined surface 607, so that when the cleaning member 7 moves, when cleaning is not needed, the cleaning member 7 can be guided by the guide groove 603 and move away from the first welding section 4 in both the horizontal and height directions. Avoiding blocking the welding area provides space for the welding operation and reduces interference with the welding process. At the same time, increasing the distance between the cleaning member 7 and the welding area helps to protect the cleaning member 7 from high temperature, splashing, etc. during the welding process, thereby extending its service life.

[0032] In some examples, the clearance groove 608 provided on the clamping block 6 matches the second welding section 5 (i.e., the connection between the rib plate 1 and the bottom plate 2). When the device is working, when the rib plate 1 passes through the through groove 602 and is placed in place with the bottom plate 2, and the clamping block 6 completes the clamping of the bottom plate 2, the second welding section 5 is exposed to the outside through the clearance groove 608. The welding equipment (such as the welding gun of an electric welder) can be directly aimed at the exposed second welding section 5 for welding. The clearance groove 608 provides a welding space for the welding process to ensure that the weld can be formed evenly and completely. And when welding the second welding section 5, such as Figure 6 As shown, the moving block 8 can be driven to move, and the cleaning member 7 can be simultaneously driven to move to a side away from the bottom plate 2 to help free up space.

[0033] In some examples, when the clamping operation of the device is started, the four clamping blocks 6 move synchronously to the middle area where the bottom plate 2 is located. Through precise position control and motion coordination, the abutment portion 601 of each clamping block 6 can fit tightly with the side of the bottom plate 2, and clamping force is applied to the bottom plate 2 from four directions, so that the bottom plate 2 is stably fixed at the center position of the four clamping blocks 6, effectively preventing it from displacement or shaking.

[0034] A cleaning member 7 is provided on both sides of each clamping block 6. When the rib plate 1 is placed in the through groove 602 and is preliminarily positioned with the bolt 3 and the bottom plate 2, the cleaning members 7 on both sides of the clamping block 6 start to work for the two first welding sections 4 (located on both sides of the rib plate 1) formed by the single rib plate 1 and the bolt 3. The cleaning members 7 approach and pass through the corresponding first welding section 4 through their own lifting and horizontal movement functions. The first welding section 4 area is cleaned by a cleaning member (such as a rotating brush, etc.) to remove impurities such as welding slag and spatter generated during welding, so as to provide a clean surface for subsequent welding.

[0035] In some examples, the two ends of the suction member 10 are respectively connected to two adjacent moving blocks 8. When one of the moving blocks 8 starts to move horizontally under the action of its driving mechanism (such as a lead screw nut pair driven by a motor, an electric push rod, etc.), the suction member 10, as a connecting medium, will transmit the movement of the moving block 8 to another adjacent moving block 8, so that the two moving blocks 8 can move synchronously. This synchronous movement method ensures the consistency of the movement of other components associated with the moving block 8 (such as the connecting plate 9, the cleaning member 7, etc.) on the clamping blocks 6 on both sides, and maintains the coordination of the device operation.

[0036] There are several air holes 1001 distributed on the air suction member 10. During the welding operation, a large amount of welding gas containing harmful components will be generated in the welding area. The air pump 11 is arranged on the clamping block 6 and is connected to the air suction member 10. When the air pump 11 is working, negative pressure will be generated, and the welding gas around the welding area will be sucked in through the air holes 1001 of the air suction member 10. As shown in this scheme, the air suction member 10 is preferably arc-shaped, which can be adsorbed from above and has a wide adsorption range to prevent it from spreading in the working environment.

[0037] In some examples, two groups of air holes 1001 are provided on the air suction member 10, and are respectively located on both sides of the air suction member 10. One group of air holes 1001 is oriented above the first welding section 4 (the connection between the bolt 3 and the rib plate 1), and the other group of air holes 1001 is oriented above the second welding section 5 (the connection between the rib plate 1 and the bottom plate 2). When the welding operation is in progress, welding gas will be generated in both the first welding section 4 and the second welding section 5. The negative pressure generated by the air pump 11 is transmitted to the two groups of air holes 1001 through the air suction member 10. Since the air holes 1001 are oriented toward the corresponding welding section, the welding gas can be quickly and effectively inhaled. For example, when welding in the first welding section 4, the welding gas generated in this area will be directly inhaled into the air suction member 10 under the negative pressure formed by the air holes 1001; similarly, the welding gas generated in the second welding section 5 will also be inhaled by the corresponding air holes 1001, so as to achieve targeted absorption of welding gas in different welding sections.

[0038] In some examples, the rotating table 12 adopts a horizontally arranged rotating axis, and a plurality of clamping blocks 6 are mounted on the rotating table 12 and can move relative to the rotating table 12. Before the welding operation is performed, according to the welding process requirements, the rotating table 12 is rotated by its own driving mechanism (such as a motor with a reducer and a gear transmission device, etc.), so that the first weld section can be in a horizontal direction, so that boat-shaped welding can be performed. Compared with traditional non-horizontal position welding, boat-shaped welding can reduce defects such as pores 1001 and slag inclusions in the weld, and improve the quality and strength of the weld. In the foundation welding of large steel structure buildings, the use of boat-shaped welding in combination with the adjustment of the rotating table 12 can significantly improve the welding quality and ensure the stability of the building structure.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure rather than to limit it. Although the present disclosure has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present disclosure may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present disclosure, which should be included in the scope of the claims of the present disclosure.
