Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and more specifically, to a hinge auxiliary welding device. Background Technology

[0002] In current industrial applications, especially in mining and industrial sites, large hinges are in high demand and come in a wide variety of sizes as key components for connection and support, to meet the specific requirements of different environments and equipment. However, due to the specific conditions of mining and industrial sites, existing hinge welding processes mainly rely on manual operation for customized processing.

[0003] This manual welding method has significant limitations, including but not limited to high safety risks. Due to the complex welding environment, operators face occupational hazards such as electric shock and burns. Welding consistency and stability are poor; manual welding makes it difficult to ensure that the weld quality of each hinge is completely identical, affecting the hinge's service life and structural strength. Welding efficiency is low; manual welding is slow and cannot meet the needs of mass production, especially when hinge sizes and specifications vary, as manually adjusting welding parameters and positions consumes even more time. Currently, while existing hinge auxiliary welding devices can provide placement positions for hinges, the safety and efficiency of welding remain low.

[0004] In other words, existing hinge auxiliary welding devices suffer from poor safety and low efficiency. Utility Model Content

[0005] The main objective of this invention is to provide a hinge auxiliary welding device to solve the problems of poor safety and low efficiency in existing hinge auxiliary welding devices.

[0006] To achieve the above objectives, this utility model provides a hinge auxiliary welding device, comprising: a base; a welding table, the welding table being disposed on the base and detachably connected to the base, the welding table including a support frame and a bearing portion and a clamping portion disposed on the support frame, the bearing portion and the clamping portion being correspondingly disposed, the bearing portion being used to place the hinge piece to be welded, the clamping portion being used to place the hinge sleeve to be welded, and the clamping portion being provided with an engaging positioning portion to divide the clamping portion into at least two clamping areas.

[0007] Furthermore, the support frame includes a first beam structure, a second beam structure, and a third beam structure. The first beam structure is parallel to the base, and the second and third beam structures are perpendicularly connected to both ends of the first beam structure to form a U-shaped support frame.

[0008] Furthermore, the support frame also includes two connecting plates, which are respectively located at the end of the second beam structure away from the first beam structure and at the end of the third beam structure away from the first beam structure. The two connecting plates are arranged opposite to each other, and the two ends of the clamping part are connected to the two connecting plates respectively, and the two ends of the bearing part are connected to the two connecting plates respectively.

[0009] Furthermore, the clamping part is parallel to the bearing part, and the clamping part is connected to or spaced apart from the bearing part. The bearing part is elongated and has a bearing surface arranged along its extension direction, which is parallel to the base.

[0010] Furthermore, the clamping part has a clamping groove, which is located on the side of the bearing surface facing the base. The clamping groove is elongated, and the opening side of the elongated clamping groove is located on the side of the clamping part away from the base.

[0011] Furthermore, the cross-sectional shape of the clamping groove along the direction perpendicular to the base is U-shaped or V-shaped; and / or the opening of the clamping groove is flush with or lower than the bearing surface, and the projection of the clamping groove on the base and the projection of the bearing surface on the base are spaced apart, partially overlapped, or seamlessly connected.

[0012] Furthermore, the clamping part extends in a direction parallel to the base, and there are one or more engaging positioning parts. When there are multiple engaging positioning parts, the multiple engaging positioning parts are spaced apart along the extension direction of the clamping part.

[0013] Furthermore, the engaging positioning part is plate-shaped, and one side of the plate-shaped engaging positioning part is fixedly connected, pivotally connected, or detachably connected to the clamping part.

[0014] Furthermore, the welding station also includes connectors, and the support frame is detachably connected to the base via at least two sets of connectors. Each set of connectors consists of interconnected legs and a connecting structure, and the connecting structure includes an abutment plate, the two sides of which are connected to the legs and the base, respectively.

[0015] Furthermore, the base has an operating table with multiple through holes arranged in an array; and / or multiple support columns are provided on the side of the base away from the welding table, with casters connected to the bottom of each support column and the casters having brakes.

[0016] According to the technical solution of this utility model, the hinge auxiliary welding device includes a base and a welding table. The welding table is disposed on the base and detachably connected to the base. The welding table includes a support frame and a bearing part and a clamping part disposed on the support frame. The bearing part and the clamping part are correspondingly disposed. The bearing part is used to place the hinge piece to be welded, and the clamping part is used to place the hinge sleeve to be welded.

[0027] To address the issues of poor safety and low efficiency in existing hinge auxiliary welding devices, this invention provides a hinge auxiliary welding device.

[0028] like Figure 1 and Figure 2 As shown, the hinge auxiliary welding device includes a base 10 and a welding table. The welding table is disposed on the base 10 and detachably connected to the base 10. The welding table includes a support frame 21 and a bearing part 22 and a clamping part 23 disposed on the support frame 21. The bearing part 22 and the clamping part 23 are correspondingly disposed. The bearing part 22 is used to place the hinge piece 31 to be welded, and the clamping part 23 is used to place the hinge sleeve 32 to be welded. The clamping part 23 is provided with a locking positioning part 24 to divide the clamping part 23 into at least two clamping areas.

[0029] By providing a base 10, the welding station is positioned for installation, which improves its stability and reliability. The detachable connection between the welding station and base 10 allows for the replacement of the welding station with a matching one based on the hinge model being welded, ensuring compatibility between the welding station and the hinge's model and size, guaranteeing welding stability, and enhancing the versatility of the hinge auxiliary welding device. The support frame 21 provides mounting positions for the bearing portion 22 and the clamping portion 23, ensuring the stability of the bearing portion 22 in supporting the hinge piece 31 to be welded, and the stability of the clamping portion 23 in holding the hinge sleeve 32 to be welded, thus contributing to the stability and safety of the welding process. By providing a locking and positioning part 24 in the clamping part 23, the clamping part 23 is divided into at least two clamping areas, so that one or more hinge sleeves 32 to be welded can be placed in one clamping area. This is beneficial for the positioning of the hinge sleeves 32 and the reasonable distribution of the positions of the hinge sleeves 32. In actual operation, multiple hinge sleeves 32 in the clamping part 23 can be welded in sequence, which helps to improve welding efficiency.

[0030] Furthermore, the hinge auxiliary welding device of this application enables the hinge piece 31 and the hinge sleeve 32 to be accurately positioned before welding, avoiding displacement of the hinge piece 31 or the hinge sleeve 32 during the welding process. This significantly reduces welding defects caused by inaccurate positioning, such as misalignment and incomplete fusion, thus improving welding quality. It is suitable for mass production of hinges in industries such as furniture, doors and windows, and luggage, greatly improving production line efficiency, product quality, and customer satisfaction. Especially in automated production lines, this device can seamlessly integrate with robotic welding systems. Through precise positioning and rapid replacement, the hinge production cycle is significantly shortened, greatly improving production efficiency and cost-effectiveness.

[0031] It should be noted that a hinge consists of a hinge piece 31 and two hinge sleeves 32. The hinge piece 31 needs to be connected to the two hinge sleeves 32 by welding. Specifically, the two ends of one side of the hinge piece 31 are welded to the two hinge sleeves 32 respectively, and the two hinge sleeves 32 are coaxially arranged.

[0032] like Figure 1As shown, the bearing portion 22 and the clamping portion 23 are disposed on the top of the support frame 21. The support frame 21 includes a first beam structure 211, a second beam structure 212, and a third beam structure 213. The first beam structure 211 is parallel to the base 10. The second beam structure 212 and the third beam structure 213 are perpendicularly connected to both ends of the first beam structure 211, respectively, to form a U-shaped support frame 21. Specifically, one end of the second beam structure 212 is perpendicularly connected to one end of the first beam structure 211, and the other end of the second beam structure 212 extends away from the base 10. One end of the third beam structure 213 is perpendicularly connected to the other end of the first beam structure 211, and the other end of the third beam structure 213 extends away from the base 10. The second beam structure 212 and the third beam structure 213 are parallel and arranged opposite to each other. The U-shaped support frame 21 enhances its stability, providing a stable installation position for the load-bearing part 22 and the clamping part 23. This helps ensure the stability of the hinge piece 31 and the hinge sleeve 32, avoids shaking during the welding process, and is suitable for welding heavy-duty hinges, improving welding accuracy and safety.

[0033] In a specific embodiment of this application, the second beam structure 212 and the third beam structure 213 have the same length, which is beneficial for the arrangement of the bearing part 22 and the clamping part 23.

[0034] Specifically, the support frame 21 also includes two connecting plates 214, which are respectively located at the ends of the second beam structure 212 and the third beam structure 213 away from the first beam structure 211. The two connecting plates 214 are arranged opposite each other, meaning that the line connecting the two connecting plates 214 is parallel to the base 10. Both ends of the clamping part 23 are connected to the two connecting plates 214, and both ends of the bearing part 22 are also connected to the two connecting plates 214, so that the clamping part 23 and the bearing part 22 are arranged parallel to each other. By setting two connecting plates 214, the assembly stability of the bearing part 22 and the clamping part 23 with the frame is ensured, thereby guaranteeing the reliability of the bearing part 22 and the clamping part 23 in use. Specifically, the connection positions of the clamping part 23 and the bearing part 22 with the connecting plate 214 are located on both sides of the connecting plate 214. This facilitates the installation and disassembly of the bearing part 22 and the clamping part 23, making it suitable for scenarios requiring frequent changes of welding workpieces, and improving the flexibility and adaptability of the device.

[0035] In one optional embodiment of this application, the clamping part 23 is connected to the supporting part 22. In another optional embodiment of this application, the clamping part 23 and the supporting part 22 are spaced apart. The arrangement can be made according to actual conditions, and this application does not limit this. The supporting part 22 is elongated and has a supporting surface 221 arranged along its extending direction, which is parallel to the base 10. The length of the supporting part 22 is equal to the length of the clamping part 23. This design allows the hinge piece 31 and the hinge sleeve 32 to be tightly aligned, improving welding accuracy and making it suitable for manufacturing precision hinges requiring high-precision welding. When multiple hinge pieces 31 need to be welded, the multiple hinge pieces 31 can be arranged sequentially or spaced apart along the extending direction of the supporting surface 221, and the portion of the hinge piece 31 to be welded extends out of the supporting surface 221 and contacts the hinge sleeve 32 in the clamping part 23.

[0036] Specifically, the clamping part 23 has a clamping groove for placing the hinge sleeve 32 to be welded. The clamping groove is located on the side of the bearing surface 221 facing the base 10, and is elongated, with its extension direction being the same as the length direction of the clamping part 23. The opening side of the elongated clamping groove is located on the side of the clamping part 23 away from the base 10, meaning the opening of the clamping groove faces the opposite direction, which facilitates the placement of the hinge sleeve 32. The design of the clamping groove can better fix the hinge sleeve 32, preventing the hinge sleeve 32 from moving during welding, thus improving the stability and efficiency of welding.

[0037] In an optional embodiment of this application, the cross-sectional shape of the clamping groove along the direction perpendicular to the base 10 is U-shaped or V-shaped. That is, the clamping groove can be a U-shaped groove or a V-shaped groove, which can be set according to the actual situation. When the cross-sectional shape of the clamping groove along the direction perpendicular to the base 10 is V-shaped, the clamping part 23 can be formed by two clamping plates fixedly connected at an angle, or by two clamping plates pivotally connected at an angle with springs. The included angle of the two clamping plates matches the size and model of the hinge sleeve 32 it clamps, thereby ensuring the positional stability of the hinge sleeve 32.

[0038] In addition, the groove of the clamping groove is set flush with or lower than the bearing surface 221. The projection of the clamping groove on the base 10 and the projection of the bearing surface 221 on the base 10 are spaced apart or at least partially overlapped or seamlessly connected. This can be set according to actual needs. It is necessary to ensure that after the hinge sleeve 32 is placed in the clamping groove, the hinge sleeve 32 is flush with the bearing surface 221. In this way, when the hinge piece 31 to be welded is placed on the bearing surface 221, the part to be welded will abut against the hinge sleeve 32 and ensure that the hinge piece 31 is in a horizontal state. This helps to ensure the reliability of welding and improves the consistency and aesthetics of welding.

[0039] like Figure 1 and Figure 2 As shown, the clamping part 23 extends in a direction parallel to the base 10, and there are one or more engaging positioning parts 24. When there are multiple engaging positioning parts 24, they are spaced apart along the extension direction of the clamping part 23. In a specific embodiment of this application, multiple engaging positioning parts 24 are spaced apart in the clamping groove along the length direction of the clamping groove, so that a space for accommodating the hinge sleeve 32 can be formed between two adjacent engaging positioning parts 24, thereby achieving a reasonable plan of the clamping groove space and facilitating the placement of the hinge sleeve 32. In an optional embodiment of this application, one or more hinge sleeves 32 can be placed between two connected engaging positioning parts 24, which can be adjusted according to actual welding requirements. The design of one or more engaging positioning parts 24 can adapt to hinge sleeves 32 of different sizes, improving the versatility of the device and making it suitable for production environments where the size of the hinge sleeve 32 varies.

[0040] In the specific implementation of this application, the engaging positioning part 24 is plate-shaped, and is perpendicular to the bearing surface 221. One side of the plate-shaped engaging positioning part 24 is fixedly connected, pivotally connected, or detachably connected to the clamping part 23. Specifically, one side of the engaging positioning part 24 is fixedly connected, pivotally connected, or detachably connected to the opening of one side of the clamping groove. When the engaging positioning part 24 is pivotally connected to the clamping groove, it can be done through a spring-loaded pivot connection. In this way, when the engaging positioning part 24 is not in use, it can automatically fold to fit against the groove wall of the clamping groove. When the engaging positioning part 24 is needed, it can be pried out. By designing the engaging positioning part 24 to be plate-shaped, not only can sufficient support be provided, but its position can also be adjusted or replaced as needed. This is suitable for scenarios that require frequent adjustments to the welding position, improving the flexibility of the device and production efficiency.

[0041] like Figure 1 As shown, the base 10 has an operating table 12 with multiple through holes arranged in an array. The through holes allow for detachable connection to the welding table, such as a bolted connection. This facilitates adjustment of the connection position between the welding table and the operating table 12 according to actual working conditions.

[0042] Specifically, a plurality of support columns 11 are provided on the side of the base 10 away from the welding table. Preferably, a support column 11 is provided at each of the four corners of the surface of the base 10 away from the welding table. The support columns 11 are fixedly, pivotally, or detachably connected to the base 10 to provide stable support for the base 10.

[0043] In an optional embodiment of this application, each support column 11 is connected to a caster wheel at its bottom, and the caster wheel has a brake to enable braking. This allows the hinge-assisted welding device to move within the workshop and achieve rapid positioning and locking, making it suitable for welding work requiring flexible movement within the workshop. This is particularly important for automated production lines, as equipment on the production line needs to be arranged and adjusted efficiently. Using this device can significantly improve the flexibility and responsiveness of the production line, providing strong support for automated production.

[0044] Alternatively, the base 10 can be removed, allowing the welding table to directly contact the ground, while still meeting the requirements for automated welding.

[0045] like Figure 1 As shown, the welding station also includes connectors. The support frame 21 is detachably connected to the base 10 via at least two sets of connectors. Specifically, the connectors are detachably connected to the base 10 via bolts. Each set of connectors consists of interconnected legs 25 and a connecting structure 26. One end of the leg 25 is fixedly connected to the first beam structure 211, and the other end of the leg 25 is connected to the connecting structure 26. The connecting structure 26 includes an abutment plate, the two sides of which are connected to the legs 25 and the base 10, respectively. Specifically, the connecting structure 26 is a U-shaped plate structure of a certain length, with a U-shaped cross-section along the direction perpendicular to the base 10. The bottom side plate of the U-shaped plate structure is the aforementioned abutment plate, which is in contact with the surface of the base 10. By designing the connectors to be detachably connected to the base 10, the welding station can be disassembled and assembled as needed, facilitating the transportation and storage of the device. It is suitable for scenarios requiring welding work in different locations and allows for easy replacement of the welding station with a matching type based on the hinge model being welded, thus improving versatility. At the same time, it helps to ensure the stability of the support frame 21, thereby ensuring the working stability of the clamping part 23 and the bearing part 22.

[0046] Furthermore, when robotic hinge welding is required, the corresponding welding table is connected to the operating surface 12 of the base 10; then, the hinge piece 31 to be welded is placed on the bearing part 22, and the hinge sleeve 32 is placed on the clamping part 23. The hinge piece 31 to be welded and the hinge sleeve 32 are then engaged and positioned by the engagement and positioning part 24, so that the engagement and positioning part corresponds to the slot of the hinge piece 31. Since the bottom of the support column 11 is equipped with universal wheels with a braking function, the hinge auxiliary welding device can be moved to the robotic welding operation area for the robot to perform the welding operation.

[0047] The hinge auxiliary welding device provided in this application, by providing a bearing part 22 and a clamping part 23 on the support frame 21, provides a stable placement position for the hinge piece 31 and hinge sleeve 32 to be welded, which is beneficial to improving welding safety and stability. It also facilitates precise positioning of the hinge piece 31 and hinge sleeve 32, improving welding accuracy and efficiency. Furthermore, the detachable connection between the support frame 21 and the base 10 via a connector, and the engagement positioning part 24 in the clamping part 23, give the device good adaptability and flexibility, enabling it to meet the welding needs of hinges of different sizes and shapes, greatly improving the convenience and application range in actual operation.

[0048] Furthermore, the casters at the bottom of the support column 11 of the base 10 further enhance the stability and mobility of the device, providing a more efficient, safe, and convenient operating environment for welding work. Meanwhile, the modular design of the hinge-assisted welding device offers significant advantages in maintenance, upgrades, and component replacement, reducing production costs and extending its service life.
