Description

Technical Field

[0001] This utility model belongs to the field of pipe fitting processing technology, specifically relating to a pipe fitting welding equipment. Background Technology

[0002] The tubular fitting welding equipment is specially designed for welding various tubular materials. It can accurately weld pipes together and overlap, and uses welding technology to ensure weld quality. It is widely used in pipe manufacturing, automotive parts processing and other fields.

[0003] A related technology (publication number CN221849064U) discloses a precision welding device for pipe fittings, including a movable base, a fixed ring, a connecting member, an abutment member, and a spacing adjustment member. The movable base is fixedly connected to the fixed ring, the fixed ring is symmetrically fixedly connected to the connecting member, and three abutment members are arranged in a ring-shaped, equally spaced array on the fixed ring. The precision welding device for pipe fittings uses a welding frame composed of the movable base, fixed ring, connecting member, and abutment members. The symmetrically arranged welding frames are connected by the spacing adjustment member. The abutment members on the fixed ring allow for convenient clamping of pipe fittings of different sizes. The spacing adjustment member controls the distance between two pipe sections and the height of the end portion, meeting the requirements for precision welding and ensuring the welding of the pipe fittings. The pipe fittings can rotate while being clamped and fixed by the welding frame, achieving full welding of the ends.

[0004] Traditional processes require workers to first perform spot welding around the joint of two pipe fittings to achieve a preliminary connection, and then perform full welding at the joint. In the spot welding stage, workers need to manually hold an electric welding machine and weld point by point along the pipe joint. During this process, workers need to frequently move their positions, and it may even involve working at heights. This method not only poses significant safety hazards, but also consumes a lot of time due to repeated manual repositioning, which greatly restricts welding efficiency. Utility Model Content

The mounting plate is fixedly installed on the support frame; the screw rod is rotatably connected to the side wall of the mounting plate; the driving plate is threadedly sleeved on the screw rod; two groups of driving rods are provided, and one end of each group of driving rods is rotatably connected to the driving plate, and the other ends of the two groups of driving rods are rotatably connected to the corresponding moving frame.

[0015] The tubular component welding equipment of this utility model has the following advantages compared with the prior art:

[0016] I. In the existing spot welding process for pipe fittings, manual hand-held welding machines are required to weld point by point along the pipe joint. During this process, workers need to frequently move their positions, and may even need to work at heights. This method not only poses significant safety hazards, but also consumes a lot of time due to repeated manual repositioning, which greatly restricts welding efficiency. This utility model can achieve dual-point synchronous spot welding for the joint of two pipe fittings, effectively avoiding the need for workers to move their positions and the possibility of working at heights in the traditional operation, significantly improving the safety of the operation process. At the same time, the dual-point synchronous spot welding processing mode greatly improves welding efficiency, ensures welding accuracy, and optimizes the overall welding quality.

[0017] Second, in the technical solution of this utility model, synchronous driving can be achieved for the free ends of the two workpieces. That is, the free ends of the two sets of workpieces can be simultaneously attached to the joint of the pipe fitting for spot welding, and the free ends of the two sets of workpieces can be simultaneously detached from the joint of the pipe fitting. This dual-point synchronous operation mode greatly ensures the synchronicity and accuracy of spot welding at the joint of the pipe fitting, effectively avoiding the misalignment problem that may be caused by traditional step-by-step spot welding, thereby significantly improving the welding quality and stability.

[0018] Third, in this utility model, by means of the coordinated operation of components such as lead screw, drive plate, and drive rod, the left and right sets of moving frames can drive the free ends of the workpieces at their respective corresponding positions to move towards or away from the joint of the pipe fittings simultaneously. Relying only on the same driving power, the two sets of free ends of the workpieces can move simultaneously, achieving precise coordinated operation.

[0019] IV. In this utility model, the free end of the workpiece can be positioned by the cooperation of components such as positioning bolts, positioning nuts, arc-shaped positioning plates and mounting bases, ensuring that the free end of the workpiece is in a stable clamped state during welding.

[0020] V. This utility model is designed to support two sets of pipe fittings. Through the cooperation of components such as a fixed base, triangular plate, rotating shaft, and rollers, the two sets of pipe fittings can be connected and supported. The rotating rollers support the pipe fittings and assist them in rotating smoothly around the rollers. After welding two points, the pipe fittings can be rotated to adjust other points to be welded to the workpiece ends, so that the joints of the pipe fittings can be welded around the workpieces in the future.

[0021] In summary, this utility model enables simultaneous spot welding at two points on the joint of two pipe fittings, effectively avoiding the need for workers to move positions and potentially work at heights in traditional operations, thus significantly improving the safety of the operation process. At the same time, the simultaneous spot welding mode greatly improves welding efficiency, ensures welding accuracy, optimizes the overall welding quality, and effectively avoids the misalignment problem at the pipe fitting joint that may occur when spot welding in steps one after the other in traditional methods, thereby significantly improving the welding quality and stability.

[0033] The following are specific implementation cases and appendices. Figures 1 to 3 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0034] A tubular component welding device includes a base (1), and further includes: a support component, a support frame (7), positioning blocks (8), a moving frame (9), a drive assembly, and a welding assembly. Two sets of tubular components (6) are rolled on the support component, and the opposite sides of the two sets of tubular components (6) are tightly connected. The connection point of the tubular components (6) is then spot welded. The support frame (7) is vertically installed on the upper surface of the base (1) to provide a position for the installation of other components. Two positioning blocks (8) are provided, which are respectively installed on the upper surface of the support frame (7), and the two positioning blocks (8) are symmetrically arranged with respect to the support frame (7). Two moving frames (9) are provided. The top of (9) slides through the outer wall of the two positioning blocks (8) respectively, and the moving direction of the moving frame (9) is limited by the positioning blocks (8) to ensure that the moving frame (9) always moves relatively smoothly relative to the support frame (7). The bottom of the two moving frames (9) slides through the side wall of the two support frames (7) respectively. The driving component is set on the support frame (7) to drive the two sets of moving frames (9) to move symmetrically to ensure that the two sets of moving frames (9) can move synchronously. The welding component is set at the bottom end of the moving frame (9) and the synchronous movement of the two sets of moving frames (9) is achieved through the synchronous movement of the two sets of welding components.

[0035] This utility model can achieve dual-point synchronous spot welding at the joint of two pipe fittings (6), effectively avoiding the need for workers to move positions and the possibility of climbing to heights in traditional operations, significantly improving the safety of the operation process. At the same time, the dual-point synchronous spot welding processing mode greatly improves welding efficiency, ensures welding accuracy, and optimizes the overall welding quality.

[0036] Main references Figure 1 and Figure 2As shown in the figure, the driving component includes: a mounting plate (18), a lead screw (19), a driving plate (20), and a driving rod (21). The mounting plate (18) is fixedly mounted on the support frame (7); the lead screw (19) is rotatably connected to the side wall of the mounting plate (18) through a bearing; the driving plate (20) is threadedly sleeved on the lead screw (19). When the lead screw (19) rotates, it can drive the driving plate (20) to move in the corresponding direction along the length of the lead screw (19); there are two groups of driving rods (21), and one end of each group of driving rods (21) is rotatably connected to the driving plate (20) through a pin shaft, and the other ends of the two groups of driving rods (21) are rotatably connected to the corresponding moving frames (9) through pin shafts; the support frame (7) is set in an "L" shape. In addition to ensuring a stable connection relationship between the support frame (7) and the base (1), it can provide enough hollow space for the placement of the pipe fitting (6), that is, there is enough space below the support frame (7) for the normal placement, rotation and welding operation of the pipe fitting (6); there are two groups of welding components, and each group of welding components includes: a spot welder (15), an electrode end (16) and a workpiece end (17). The spot welder (15) is arranged on the side wall of the base (1); the electrode end (16) and the workpiece end (17) are respectively connected to the spot welder (15).

[0037] By driving the rotation of the lead screw (19), the driving plate (20) is promoted to move horizontally along the lead screw (19), so as to promote the two mounting plates (18) to drive the corresponding moving frames (9) to move synchronously, so as to promote the two groups of moving frames (9) to respectively push the two groups of mounting seats (11) and the two workpiece ends (17) positioned in the mounting seats (11) close to the butt joint of the pipe fitting (6), so as to realize the double-point spot welding processing of the butt joint of the pipe fitting (6).

[0038] Mainly refer to Figure 3 It should be noted that in the original text, the description of the shape of the support frame as "冂" may be incorrect. I translated it as "L" according to the possible correct meaning inferred from the context. If there is an error in my understanding, please correct it according to the actual situation.As shown, the bottom ends of the two movable frames (9) are respectively provided with positioning components. Each positioning component includes: a mounting base (11), a positioning bolt (12), a positioning nut (13), and an arc-shaped positioning piece (14). The mounting base (11) is installed at the bottom end of the movable frame (9); the positioning bolt (12) is threaded through the outer wall of the mounting base (11) from top to bottom; the positioning nut (13) is threaded onto the positioning bolt (12), and the lower surface of the positioning nut (13) is in contact with the upper surface of the mounting base (11); the arc-shaped positioning piece (14) is installed at the bottom end of the positioning bolt (12), and the shape of the arc-shaped positioning piece (14) is set to arc; the workpiece end (17) is provided with The workpiece is placed in the inner cavity of the mounting base (11) and the arc-shaped positioning piece (14) is attached to the upper surface of the workpiece end (17). The workpiece end (17) is placed in the inner cavity of the mounting base (11) at the corresponding position. By rotating the positioning bolt (12), the arc-shaped positioning piece (14) is finally attached to the upper surface of the workpiece end (17) to achieve the locking and positioning of the workpiece end (17) in the inner cavity of the mounting base (11). Then, by rotating the positioning nut (13), the positioning bolt (12) is locked on the mounting base (11), that is, the arc-shaped positioning piece (14) is stably positioned on the workpiece end (17), and the two sets of workpiece ends (17) after positioning are symmetrically arranged relative to the pipe (6).

[0039] Main references Figure 1 and Figure 2 As shown, the supporting components are provided in four sets. Each set of supporting components includes: a fixed seat (2), a triangular plate (3), a rotating shaft (4), and a roller (5). The fixed seat (2) is fixedly installed on the upper surface of the base (1); the triangular plate (3) is installed inside the fixed seat (2); there are two sets of rotating shafts (4), and the two sets of rotating shafts (4) are respectively set at the angle between the triangular plate (3) and the fixed seat (2) through bearings; there are two sets of rollers (5), and the two sets of rollers (5) are respectively installed on the two rotating shafts (4);

[0040] By cooperating with components such as the fixed seat (2), triangular plate (3), rotating shaft (4), and roller (5), the two sets of pipe fittings (6) can be connected and supported. The rotating roller (5) supports the pipe fittings (6) and assists the pipe fittings (6) to rotate smoothly around the surface of the roller (5). After welding two points, the pipe fittings (6) are rotated to adjust the other points to be spot welded to the workpiece end (17) so that the connection of the pipe fittings (6) can be processed by circumferential multi-point spot welding.

[0041] Four sets of supporting components are symmetrically arranged on the front and back sides of the pipe fitting (6) to ensure that the supporting components can accurately connect the two sets of pipe fittings (6) and ensure the precision of the weld joint at the pipe fitting (6) joint. Two sets of workpiece ends (17) are symmetrically arranged relative to the pipe fitting (6) to ensure that the free ends of the two workpiece ends (17) can achieve synchronous drive. That is, the free ends of the two sets of workpiece ends (17) can simultaneously fit into the joint of the pipe fitting (6) for spot welding, and the free ends of the two sets of workpiece ends (17) can simultaneously detach from the joint of the pipe fitting (6). This dual-point synchronous operation mode greatly ensures the synchronicity and accuracy of spot welding at the joint of the pipe fitting (6), effectively avoiding the misalignment problem at the joint of the pipe fitting (6) that may be caused by traditional step-by-step spot welding, thereby significantly improving the welding quality and stability.

[0042] It is worth noting that in this application, the spot welding machine (15) is a commonly used spot welding machine in the existing market. It has two output ends, namely the welding rod end (16) and the workpiece end (17) in this application. Its function is to form a circuit between the welding rod and the workpiece. When the welding rod contacts the workpiece and ignites the arc, a strong current passes through the gap between the welding rod and the workpiece to generate a high-temperature arc, which makes the contact part between the welding rod and the workpiece melt rapidly, thereby achieving the purpose of welding. The spot welding machine (15) is a common model, and its model will not be described in detail here. The screw 19 is a screw 19 in the existing market that can achieve self-locking. When it stops rotating, it can achieve self-locking and will not be affected by external force to rotate. The model of the above-mentioned existing components will not be limited or described in detail here.

[0043] The working principle of a tubular component welding equipment in this embodiment is as follows:

[0044] Place the two sets of pipe fittings (6) on the rollers (5) at the corresponding positions. The rollers (5) can support the pipe fittings (6) during welding. Position the workpiece end (17) of the spot welding machine (15): Place the workpiece end (17) in the inner cavity of the mounting seat (11) at the corresponding position. Rotate the positioning bolt (12) to make the arc-shaped positioning piece (14) finally fit on the workpiece end (17) to achieve the locking and positioning of the workpiece end (17) in the inner cavity of the mounting seat (11). Then rotate the positioning nut (13) to make the positioning bolt (12) lock on the mounting seat (11), that is, to achieve the stable positioning of the arc-shaped positioning piece (14) on the workpiece end (17) and ensure that the two sets of workpiece ends (17) are symmetrically set relative to the pipe fittings (6) after positioning.

[0045] By turning on the spot welding machine (15) for spot welding, the drive screw (19) is rotated, causing the drive plate (20) to move horizontally along the screw (19), so that the two mounting plates (18) drive the corresponding moving frames (9) to move synchronously, so that the two sets of moving frames (9) respectively push the two sets of mounting seats (11) and the two sets of workpiece ends (17) after being positioned in the mounting seats (11) to approach the joint of the pipe fitting (6), thereby realizing the double-point spot welding of the joint of the pipe fitting (6);

[0046] This utility model can achieve dual-point synchronous spot welding at the joint of two pipe fittings (6), effectively avoiding the need for workers to move positions and the possibility of working at heights in traditional operations, significantly improving the safety of the operation process. At the same time, the dual-point synchronous spot welding processing mode greatly improves welding efficiency and ensures welding accuracy, optimizes the overall welding quality, and the dual-point synchronous operation mode effectively avoids the misalignment problem at the joint of the pipe fittings (6) that may be caused by traditional step-by-step spot welding, thereby significantly improving the welding quality and stability.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
