Description

Technical Field

[0001] The embodiments of the present disclosure relate to the technical field of anchor welding equipment, and in particular, to an automated anchor welding device. Background Art

[0002] Traditional anchor welding relies primarily on manual labor to place the ribs, and the entire welding process lacks a reliable and effective fixture. Ribs are affected by a variety of factors, including the electromagnetic force generated by the welding arc, thermal deformation during welding, and operator contact, causing them to shift. This displacement of the ribs changes the weld seam position, making it difficult to maintain constant welding parameters. This leads to reduced weld quality, frequent weld irregularities, cold welds, and desoldering, reducing the load-bearing capacity and stability of the anchor. Summary of the Invention

[0003] To overcome the above-mentioned defects, the embodiments of the present disclosure provide 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, and desoldering.

[0004] According to one aspect, at least one embodiment of the present disclosure provides an automated anchor welding device, comprising: a device for welding a rib plate to a base plate and a bolt, wherein the connection between the bolt and the rib plate is a first welding section, and the connection between the rib plate and the base plate is a second welding section, characterized in that it includes:

[0005] At least two clamping blocks, each having an abutting portion for abutting against a side edge of the base plate, the clamping blocks being movably arranged and configured to move closer to or farther from each other after movement, for jointly clamping the base plate via the abutting portion;

[0006] The clamping block also has a through slot, which is located on one side of the abutting portion and extends toward the abutting portion and is connected to one side of the abutting portion. The through slot is used for the rib plate to pass through, and its side walls are used to contact both sides of the rib plate.

[0007] For example, an automated foot welding device provided in at least one embodiment of the present disclosure further includes: a cleaning part, which is raised and lowered and moved horizontally and is arranged on the clamping block, with its raising and lowering direction being parallel to the moving direction of the corresponding clamping block, and its horizontal moving direction being parallel to the extension direction of the through groove, and is configured to approach or move away from the first welding section after being raised and lowered, and pass through one side of the first welding section after being moved horizontally and is used to clean the area.

[0008] 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. The automated foot welding device further includes:

[0009] 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;

[0010] a connecting plate, one end of which is rotatably mounted on the moving block and the other end of which is rotatably mounted on the cleaning member, wherein the connecting plate is configured so that after the moving block moves horizontally, the connecting plate swings accordingly;

[0011] A limiting portion is provided on the side wall of the moving block. The limiting portion is located on 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.

[0012] For example, in an automated foot welding device provided by at least one embodiment of the present disclosure, the guide groove further includes 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 movement, and the width of the second guide section is configured to allow the cleaning member to be raised and lowered;

[0013] 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 cause the connecting plate to swing.

[0014] For example, in an automated anchor 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;

[0015] The guide groove is located on the inclined surface;

[0016] The connecting plate is rotatably and slidably arranged on the cleaning member.

[0017] 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.

[0018] 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 base plate located in the middle of the four clamping blocks after movement;

[0019] 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.

[0020] 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:

[0021] An air suction member, one end of which is provided on one of the moving blocks, and the other end of which is provided on another adjacent moving block, moves along with the one moving block and synchronously drives the other adjacent moving block to move synchronously;

[0022] The air suction member has a plurality of air holes, and the air holes are configured to absorb welding gas;

[0023] An air pump is provided on the clamping block and is communicated with the air suction member.

[0024] For example, in an automated foot 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 component and face above the first welding section and the second welding section, respectively, and are used to absorb the welding gas of the first welding section and the second welding section, respectively.

[0025] For example, an automated anchor welding device provided in at least one embodiment of the present disclosure further includes: a rotating table, which is rotatably arranged with its rotation axis arranged horizontally, and the plurality of clamping blocks are movably arranged on the rotating table.

[0026] The beneficial effects of the embodiments of the present disclosure are:

[0027] In the present disclosure, the through-slot guides the ribs, allowing them to maintain a stable position during welding. During welding of the first weld section (where the bolts connect to the ribs) and the second weld section (where the ribs connect to the base plate), the ribs do not wobble or shift due to lack of restraint, thus ensuring the quality of the welded joint. Compared to traditional manual fastening of the ribs and base plate, this device simply places the base plate in the proper position, activates the clamping block mechanism to clamp the base plate, and then inserts the ribs through the through-slot. This simplifies the operation process, reduces labor intensity, and improves work efficiency. In factories that mass-produce footings, this convenient operation enables rapid loading and welding, significantly improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The present disclosure will be further described in detail below with reference to 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.

[0038] To simplify the drawings, only the parts relevant to the disclosure are schematically shown in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically shown or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0039] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on the specific circumstances.

[0040] In the present disclosure, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature includes the first feature being 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 the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0041] In the description of this embodiment, the terms "up", "down", "left", "right", etc., and the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present disclosure.

[0042] 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.

[0043] like Figures 1 to 7As shown, it shows an automated foot welding device disclosed in the present invention. In some examples, at least two clamping blocks 6 are movable. When welding operations are required, the clamping blocks 6 are moved closer to or farther away from each other through a moving mechanism (e.g., a motor-driven screw mechanism, a cylinder drive mechanism, or other common linear motion drive methods). The solution of this 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 approach each other, the abutment portion 601 abuts against the side of the base plate 2. The 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.

[0044] The through-slot 602 is located on one side of the abutment portion 601 and communicates with the side of the abutment portion 601. This allows the rib 1 to pass through the through-slot 602 and enter under the abutment portion 601. When placing the rib 1, the rib 1 is passed through the through-slot 602. Because the sidewalls of the through-slot 602 contact both sides of the rib 1, the horizontal movement freedom of the rib 1 (perpendicular to the length of the rib 1) is restricted. Therefore, during the welding process, the position of the rib 1 is confined within the range determined by the through-slot 602, which serves as an auxiliary guide.

[0045] 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 shifting during the welding process due to factors such as welding stress and operation collisions. This ensures the accuracy of the bottom plate 2 position during welding and provides 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 subsequently welded bolts 3 and the rib 1 and bottom plate 2 higher, and the stability of the equipment after installation is better.

[0046] The guiding effect of the through slot 602 on the rib plate 1 allows it to maintain a stable position during welding. During the welding of the first welding section 4 (where the bolt 3 connects to the rib plate 1) and the second welding section 5 (where the rib plate 1 connects to the base plate 2), the rib plate 1 will not wobble or shift due to lack of restraint, thus ensuring the quality of the welded joint. Compared to the traditional manual fastening of the rib plate 1 and base plate 2, this device only requires placing the base plate 2 in the appropriate position, activating the clamping block 6 to move the mechanism to clamp the base plate 2, and then inserting the rib plate 1 through the through slot 602. This simplifies the operation process, reduces labor intensity, and improves work efficiency. In factories that mass-produce footings, this convenient operation allows for rapid loading and welding, significantly improving production efficiency.

[0047] In some examples, a cleaning member 7 is mounted on the clamping block 6 and is capable of both lifting and horizontal movement. Its lifting direction is parallel to the movement direction of the corresponding clamping block 6, allowing the cleaning member 7 to adjust its spacing from the first welding section 4, moving closer to or further away from the first welding section 4. After the cleaning member 7 is moved to a suitable position on one side of the first welding section 4, its cleaning component (which can be a brush of a certain hardness) cleans the first welding section 4 area. For example, the area 20-30 mm to the side of the first welding section 4 is cleaned before and after welding. Before welding, impurities such as oil, rust, moisture, and dust may be present on the weld surface. If these impurities are introduced into the weld, they can cause defects such as porosity 1001, slag inclusions, and cracks, reducing the weld's mechanical properties and density. Cleaning the area 20-30 mm to the side of the first welding section 4 effectively removes impurities, ensuring good metal fusion during welding and ensuring weld quality and performance. Cleaning this area also facilitates smoother flow of the weld pool. If there are impurities on the weldment surface, they may hinder the flow of the molten pool metal, resulting in poor weld formation, such as uneven weld width, unevenness, undercuts, etc. After cleaning, the molten pool metal can spread and solidify better, forming a beautiful and uniform weld.

[0048] After welding, cleaning this area removes impurities such as spatter and slag generated during the welding process, leaving the weld surface and surrounding areas clearly exposed. This allows inspectors to accurately observe the weld's appearance quality, such as the presence of defects such as pores (1001), cracks, and lack of fusion. If these defects are not discovered and addressed promptly, they may affect the safety and reliability of the welded structure.

[0049] In some examples, the guide groove 603 is provided on the clamping block 6, and its first guide section 604 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.

[0050] One end of the connecting plate 9 is pivotally mounted on the moving block 8, and the other end is pivotally mounted on the cleaning member 7. The length of the connecting plate 9 allows the moving block 8 to be moved directly above the cleaning member 7. At this point, the distance 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, it drives the cleaning member 7 via the connecting plate 9. Because both ends of the connecting plate 9 are pivotally connected, protrusions are provided on the side walls of the moving block 8 to enhance movement stability. These stoppers 801 restrict the movement of the connecting plate 9, ensuring stable movement of the cleaning member 7.

[0051] 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 with the connection point with the moving block 8 as the axis, and after the swing, it 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.

[0052] 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 to different height positions, meeting the needs of cleaning welding areas at different heights in a variety of welding scenarios. Compared to 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. 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 upwards when cleaning is not required, without blocking or affecting the normal welding process.

[0053] In some examples, the inclined surface 607 of the clamping block 6 extends vertically and gradually moves away from the through-slot 602 from bottom to top. A guide groove 603 is provided on the inclined surface 607. This allows the cleaning member 7 to be guided by the guide groove 603 and away from the first welding section 4 both horizontally and vertically when cleaning is not required. This avoids obstructing the welding area, provides space for welding operations, and reduces interference with the welding process. Furthermore, the increased distance between the cleaning member 7 and the welding area helps protect it from high temperatures, spatter, and other effects during welding, thereby extending its service life.

[0054] 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 base 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 base plate 2, and the clamping block 6 completes the clamping of the base plate 2, the second welding section 5 is exposed to the outside through the clearance groove 608. Welding equipment (such as the welding gun of an electric welder) can be directly aimed at the exposed second welding section 5 for welding operations. The clearance groove 608 provides a welding space for the welding process, ensuring that the weld can be formed evenly and completely. And when welding the second welding section 5, as Figure 6As 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.

[0055] In some examples, when the device's clamping operation is activated, the four clamping blocks 6 move synchronously toward the central area of ​​the base plate 2. Through precise position control and coordinated movement, the abutment portion 601 of each clamping block 6 closely aligns with the side of the base plate 2, exerting a clamping force on the base plate 2 from four directions. This stabilizes the base plate 2 at the center of the four clamping blocks 6 and effectively prevents it from shifting or shaking.

[0056] Each clamping block 6 is equipped with a cleaning element 7 on either side. After the rib 1 is placed in the through slot 602 and initially aligned with the bolts 3 and base plate 2, the cleaning elements 7 on either side of the clamping block 6 begin operating, targeting the two first weld sections 4 formed by the rib 1 and the bolts 3 (located on either side of the rib 1). Using their lifting and horizontal movement capabilities, the cleaning elements 7 approach and pass along the corresponding first weld sections 4. Using a cleaning element (such as a rotating brush), the first weld sections 4 are cleaned to remove impurities such as welding slag and spatter generated during the welding process, providing a clean surface for subsequent welding.

[0057] In some examples, the ends of the suction element 10 are connected to two adjacent moving blocks 8. When one moving block 8 begins to move horizontally under the action of its drive mechanism (such as a motor-driven screw-nut pair or an electric push rod), the suction element 10, acting as a connecting medium, transmits the motion of the moving block 8 to the other adjacent moving block 8, enabling the two moving blocks 8 to move synchronously. This synchronized movement ensures that other components associated with the moving block 8 (such as the connecting plate 9 and the cleaning element 7) move consistently on the clamping blocks 6 on both sides, maintaining the coordinated operation of the device.

[0058] The suction element 10 is provided with a number of air holes 1001. During welding, a large amount of welding gas containing harmful substances is generated in the welding area. An air pump 11 is mounted on the clamping block 6 and connected to the suction element 10. When operating, the air pump 11 generates negative pressure, drawing the welding gas around the welding area through the air holes 1001 in the suction element 10. As shown in this embodiment, the suction element 10 is preferably curved, enabling suction from above and over a wide range to prevent the gas from spreading in the working environment.

[0059] In some examples, the air suction member 10 is provided with two sets of air holes 1001, one located on either side of the member 10. One set of air holes 1001 faces above the first welding section 4 (where the bolt 3 connects to the rib plate 1), while the other set of air holes 1001 faces above the second welding section 5 (where the rib plate 1 connects to the base plate 2). During welding, welding gas is generated in both the first and second welding sections 4 and 5. The negative pressure generated by the air pump 11 is transmitted through the air suction member 10 to the two sets of air holes 1001. Because the air holes 1001 are oriented toward the corresponding welding sections, the welding gas is quickly and efficiently drawn in. For example, during welding in the first welding section 4, the welding gas generated there is directly drawn into the air suction member 10 due to the negative pressure created by the air holes 1001. Similarly, the welding gas generated in the second welding section 5 is also drawn in by the corresponding air holes 1001, achieving targeted absorption of welding gas from different welding sections.

[0060] In some examples, the rotating table 12 adopts a horizontally arranged rotation axis, and multiple clamping blocks 6 are mounted on the rotating table 12 and can move relative to the rotating table 12. Before the welding operation, according to the requirements of the welding process, 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, thereby enabling boat-shaped welding. Compared with traditional non-horizontal position welding, boat-shaped welding can reduce defects such as porosity 1001 and slag inclusions in the weld, thereby improving the quality and strength of the weld. In the foundation welding of large steel structures, the use of boat-shaped welding in conjunction with the adjustment of the rotating table 12 can significantly improve the welding quality and ensure the stability of the building structure.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure and are not limiting. 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, and all of these should be included in the scope of the claims of the present disclosure.
