Description

Technical Field

[0001] This utility model relates to the field of arc weld seam welding technology, specifically to a multifunctional welding device. Background Technology

[0002] Metal enclosures used to hold liquids or powders generally consist of a base plate and four uprights. The uprights can be integrally bent or welded from several separate plates. The joints between the base plate and the uprights are usually straight-line welds. When the enclosure has curved corners, the overlaps at the four corners of the base plate and uprights are all curved welds. Currently, there are two common methods for handling curved welds. The first method uses a multi-axis welding robot, which offers high welding precision but has a complex robot structure, resulting in higher equipment costs. This is not feasible for most small-scale processing and manufacturing enterprises. The first method has poor versatility; the second method involves fixing the upright plate upside down on the fixture, laying the base plate directly on top of the upright plate, and then welding manually. However, this method is limited by the machining precision of the upright plate, resulting in poor flatness at the top end. Misalignment and loose fit are common at the joint between the upright plate and the base plate, causing welding misalignment. Furthermore, the base plate's fixing and limiting structure is complex, and its versatility is poor when the height difference of the housing is too large, requiring frequent replacement of the limiting structure. Therefore, it is necessary to optimize the existing technology to reduce equipment costs, improve welding precision, and enhance the versatility of the welding equipment. Utility Model Content

At the same time, the notch is set precisely to align with the material clamping area, which can effectively avoid the influence of the material support frame on the welding effect. While ensuring the welding effect, the complexity of the welding equipment parts is simplified, reducing the equipment cost; at the same time, the arrangement of the base plate at the bottom and the upright plate at the top expands the applicable range of the upright plate height, expands the application range of the welding device, improves the versatility of the welding device, and makes it more suitable for small processing and manufacturing enterprises.

Detailed Implementation

[0053] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0054] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product.

In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0055] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0056] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0057] Example 1, refer to Figures 1-6 This is the first embodiment of the present invention, which proposes a multifunctional welding device.

[0058] In this embodiment, the specific components include a frame 1, a material support frame 2, two stop bars 4, and a gun holder 6. The frame 1 has a certain height, and the workpiece is divided into two parts. The first part is a flat base plate with curved edges, and the base plate is rectangular in shape. The second part is a vertical plate with curved edges that forms a closed loop. The curved edges on the base plate correspond to the curved edges on the vertical plate.

[0059] In use, according to the size and model of the base plate, apply external force to drive the material support frame 2 to slide, adjust the distance between the welding gun and the notch 3 to ensure the effective working distance of the welding gun; then align the arc edge on the base plate with the joint of the two stop rods 4 and insert it into the material clamping area 5. The two mutually perpendicular sides of the base plate abut against the lower ends of the two stop rods 4 respectively; the two mutually perpendicular side walls of the upright plate abut against the upper ends of the two stop rods 4 respectively; the two mutually perpendicular stop rods 4 limit the position of the base plate and the upright plate, improve the neatness of the arc edge of the base plate and the arc edge of the upright plate, and at the same time ensure the stability of the base plate with the support of the material support frame 2.

[0060] Then, the welding torch is started, and an external force is applied to drive the torch holder 6 to rotate. The axis of rotation of the torch holder 6 coincides with the axis of rotation of the arc-shaped edge of the base plate, ensuring the consistency of the distance between the welding torch and the arc-shaped edge, and improving the consistency of the welding effect. At the same time, the notch 3 is set precisely to align with the material clamping area 5, which can effectively avoid the influence of the material support frame 2 on the welding effect. While ensuring the welding effect, the complexity of the welding equipment parts is simplified, and the equipment cost is reduced. At the same time, the arrangement of the base plate at the bottom and the upright plate at the top expands the applicable range of the upright plate height, expands the application range of the welding device, improves the versatility of the welding device, and makes it more suitable for small processing and manufacturing enterprises.

[0061] Example 2, refer to Figures 1-6 This is the second embodiment of the present invention. Based on the first embodiment, this embodiment further adds a guide rail 7 and a slider 8, as well as a second guide rail 9, a second slider 10, a second lead screw 11, and a second turntable 12. In use, an external force is applied around the second lead screw 11 to drive the second turntable 12 to rotate. The second turntable 12 drives the second lead screw to rotate, and the second lead screw, through the threaded slider 10, moves the material support 2 closer to or further away from the welding torch, achieving sliding adjustment of the material support 2. The guide rail 7 and the slider 8 constrain and guide the sliding direction of the material support 2, preventing skewness and improving sliding stability. The turntable 12 further improves the ease of adjusting the material support 2.

[0062] Example 3, refer to Figures 1-6This is the third embodiment of the present invention. Based on the first embodiment, this embodiment further refines the structure of the welding device by adding a swing arm 13, a lifting support 14, a guide rail 15, a sliding component 16, a stand 17, a lead screw 18, a turntable 19, and a rotating handle 20. In use, a rotation driver and a control console are provided on the frame 1. The rotation driver preferably has a motor, and the control console can adjust the start / stop and rotation speed of the rotation driver. The rotation driver drives the swing arm 13 to rotate, and the swing arm 13 sequentially drives the guide rail 15, the sliding component 16, the stand 17, the lead screw 18, the turntable 19, the lifting support 14, and the gun holder 6 to rotate in the same direction. With the help of the rotation of the swing arm 13, the welding gun completes the welding of the arc-shaped edge of the workpiece. During operation, external force can be applied to drive the sliding component 316 to slide along the guide rail 315, adjusting the distance between the stand 17, lead screw 318, turntable 319, lifting support 14, gun holder 6, and material support 2, thereby adjusting the distance between the welding torch and the workpiece. By driving the rotating handle 320 to rotate around the lead screw 318, the turntable 319 and lead screw 319 rotate synchronously. The rotation of the lead screw 318 drives the threaded lifting support 14 to move up and down, thus adjusting the height of the gun holder 6 and the welding torch. Rotating the gun holder 6 adjusts the orientation of the welding torch. This combination of structures improves the versatility of the welding device, better serving various workpiece specifications while reducing equipment procurement costs for enterprises. The rotating handle 320 also facilitates manual adjustment, reducing the intensity of the applied force.

[0063] Example 4, refer to Figures 1-6 This is the fourth embodiment of the present invention. Based on the first embodiment, this embodiment further adds a limiting member 21 and a buffer pad 22. Preferably, there are two limiting members 21. In the plane formed by the swing arm 13 swinging, a limiting member 21 is provided on both sides of the swing arm 13. When the swing arm 13 starts to rotate, the swing arm 13 will gradually approach one limiting member 21 and move away from the other limiting member 21 until the swing arm 13 comes into contact with the buffer pad 22 on one of the limiting members 21. The buffer pad 22 buffers the impact force brought by the swing arm 13 when it swings. The swing range of the swing arm 13 is constrained by the limiting member 21 to avoid the swing angle of the swing arm 13 being too large, which may cause damage or impact to the non-welding area on the workpiece. At the same time, it ensures the safety of the welding torch and reduces the risk of collision.

[0064] Example 5, refer to Figures 1-4This is the fifth embodiment of the present invention. Based on the first embodiment, this embodiment further adds two proximity switches 23 and two signal blocking components 24. One proximity switch 23 corresponds to one signal blocking component 24. In the plane formed by the swing of the swing arm 13, one proximity switch 23 and one signal blocking component 24 are provided on each side of the swing arm 13. When the swing arm 13 rotates, the proximity switch 23 on the first side of the swing arm 13 gradually approaches the signal blocking component 24. With the help of the mutually cooperating proximity switch 23 and signal blocking component 24, the position of the swing arm 13 is identified and limited, so as to avoid the swing angle of the swing arm 13 being too large, resulting in welding errors or collision accidents, and eliminating potential risks.

[0065] Example 6, refer to Figures 1-8 This is the sixth embodiment of the present invention. Based on the first embodiment, this embodiment further adds a guide rail 25, a sliding member 27, and a locking pin 29. In use, when the arc-shaped edge of the base plate coincides with the arc-shaped edge of the upright plate, the base plate, the upright plate, and the stop bar 4 are all in contact. When the arc-shaped edge of the base plate is misaligned and parallel to the arc-shaped edge of the upright plate, the sliding member 27 is installed on the guide rail 25, and the side of the sliding member 27 away from the guide rail 25 falls into the clamping area 5 and abuts against two mutually perpendicular side walls on the upright plate. This ensures that the upright plate and the base plate are matched and improves the accuracy of the welding position. At the same time, depending on the size of the curved edge of the upright plate, an external force can be applied to drive the sliding component 27 to slide along the guide rail 25. When the slot 1 26 and the slot 2 28 are aligned, the locking pin 29 is engaged in any set of mutually aligned slots 1 26 and slot 2 28 to ensure that the sliding component 27 and the upright plate are always in contact during welding.

[0066] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
