Description

Technical Field

[0001] This utility model relates to the field of home furnishing accessories processing technology, specifically to a welding device for trolley pipe fittings. Background Technology

[0002] Currently, in the production of trolley-type household products involving the welding of pipe fittings, welding of components requiring welding is often achieved through either robotic or manual welding. This approach incurs high costs for both equipment and labor, and requires more equipment when there are many weld points, resulting in a large footprint and low efficiency. As businesses grow, their demands for efficiency and automation increase, and existing welding methods often struggle to meet the requirements of high efficiency and low cost for mass production. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the purpose of this invention is to provide a welding device for pipe fittings on a trolley, improving the welding efficiency of pipe fittings and ensuring product quality.

[0004] This utility model is achieved through the following technical solution:

[0005] A trolley-mounted pipe welding device includes: grippers, two sets of positioning mechanisms, four sets of welding mechanisms, four sliding plates, four servo motors, and a worktable. The grippers grip the pipe. The four servo motors are all fixed to the worktable by fixing plates. Each servo motor cylinder has a welding mechanism vertically fixed to it by a sliding plate. The two sets of positioning mechanisms are fixed to the worktable and are located at both ends of the pipe. The four sets of welding mechanisms are distributed at the welding positions of the pipe.

[0006] Preferably, the positioning mechanism includes a positioning block and a positioning cylinder. The telescopic end of the positioning cylinder is provided with a positioning block, which can abut against one end of the pipe fitting. The cylinder body of the positioning cylinder is fixed on the worktable.

[0007] Preferably, a slide rail and a base plate are respectively provided on both sides of the workbench. The cylinder body of the positioning cylinder of one positioning mechanism and two welding mechanisms are fixed on the sliding base plate. The cylinder body of the positioning cylinder of the other positioning mechanism is fixed on the top surface of the positioning plate. The bottom surface of the positioning plate is fixed to the base plate by a positioning rod. The other two welding mechanisms are fixed to the base plate. The bottom surface of the base plate is provided with a base plate fixing rod and fixed to the workbench.

[0008] Preferably, the welding mechanism includes a welding torch, a welding torch holder, and a welding torch fixing rod. The welding torch is positioned to be welded on the pipe fitting. The welding torch is connected to the welding torch fixing rod by the welding torch holder, and the welding torch fixing rod is vertically fixed to the sliding plate.

[0009] Preferably, the welding mechanism is further provided with a baffle, which is horizontally sleeved on the welding torch fixing rod and fixed between the sliding plate and the welding torch clamping seat.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention arranges four welding mechanisms around the welding points of the pipe fittings to be welded, enabling simultaneous welding of multiple welding points on the same pipe fitting within a limited space and with minimal equipment investment. For pipe fittings of different sizes, the angle and forward / backward position of the welding torch can be adjusted by adjusting the position of the welding torch holder and the sliding plate. This method is simple, efficient, and inexpensive, thus matching the welding position and size requirements of the drawings, improving the welding efficiency of pipe fittings, and ensuring product quality. Attached Figure Description

[0012] To more clearly illustrate the technical solutions of the embodiments of this utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0013] Figure 1 This is a three-dimensional structural diagram of the welding device for pipe fittings for a trolley according to this utility model.

[0014] The components include: gripper 1, positioning block 2, positioning cylinder 3, positioning plate 4, positioning rod 5, welding torch 6, welding torch holder 7, welding torch fixing rod 8, baffle 9, sliding plate 10, servo motor 11, sliding base plate 12, slide rail 13, fixing plate 14, base plate 15, base plate fixing rod 16, and worktable 17. Detailed Implementation

[0015] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings. Figure 1A trolley-mounted pipe welding device is shown, comprising: a gripper 1, two sets of positioning mechanisms, four sets of welding mechanisms, four sliding plates 10, four servo motors 11, and a worktable 17. The gripper 1 grips the pipe and works in conjunction with a moving module and a cylinder, enabling unmanned loading and unloading, thus reducing costs and increasing efficiency for enterprises. The four servo motors 11 are all fixed to the worktable 17 via fixing plates 14. Each servo motor 11 has a welding mechanism vertically fixed to its cylinder via a sliding plate 10. The two sets of positioning mechanisms are fixed to the worktable 17, located at both ends of the pipe. The four sets of welding mechanisms are distributed at the welding positions on the pipe. By arranging four sets of welding mechanisms around the welding points of the pipe, multiple welding points on the same pipe can be welded simultaneously in a limited space using minimal equipment, improving welding efficiency and ensuring product quality.

[0017] The positioning mechanism includes a positioning block 2 and a positioning cylinder 3. The telescopic end of the positioning cylinder 3 is equipped with a positioning block 2, which can abut against one end of the pipe fitting. The cylinder body of the positioning cylinder 3 is fixed on the worktable 17. When the telescopic end of the positioning cylinder 3 begins to extend, the positioning blocks 2 in the left and right sets of positioning mechanisms simultaneously fix the left and right ends of the pipe fitting.

[0018] The workbench 17 has slide rails 13 and a base plate 15 on both sides. The cylinders of one positioning mechanism's positioning cylinder 3 and two welding mechanisms are fixed to the sliding base plate 12. The cylinders of the other positioning mechanism's positioning cylinder 3 are fixed to the top surface of the positioning plate 4. The bottom surface of the positioning plate 4 is fixed to the base plate 15 via positioning rods 5. The other two welding mechanisms are also fixed to the base plate 15. The bottom surface of the base plate 15 has base plate fixing rods 16 fixed to the workbench 17. When the pipe fitting dimensions change or need to be replaced, the movement distance of the base plate 15 can be adjusted to adjust the position of the welding torch 6 to suit the welding position.

[0019] The welding mechanism includes a welding torch 6, a welding torch holder 7, and a welding torch fixing rod 8. The welding torch 6 is positioned to be welded on the pipe fitting. The welding torch 6 is connected to the welding torch fixing rod 8 by the welding torch holder 7, and the welding torch fixing rod 8 is vertically fixed to the sliding plate 10. With four welding mechanisms and four welding torches 6, when welding pipe fittings, if there are dimensional deviations, or when welding different pipe fittings, or for pipe fittings of different sizes, the welding angle of the welding torch 6 can be adjusted by adjusting the welding torch holder 7. The corresponding servo motor 11 is adjusted to adjust the corresponding sliding plate 10, thereby adjusting the forward and backward position of the welding torch 6 to achieve the welding position and dimensional requirements marked on the drawing. Furthermore, the welding torch 6 is designed with an angle for each welding point, reducing the number of servo motors required for the welding torch 6 to return to its original position after welding from two to one. This effectively reduces investment costs and space requirements.

[0020] To prevent welding residue from falling onto the workbench 17 or other components during welding, a baffle 9 is provided on the welding mechanism. The baffle 9 is horizontally sleeved on the welding torch fixing rod 8 and fixed between the sliding plate 10 and the welding torch clamping seat 7.

[0021] The working principle of this utility model:

[0022] like Figure 1 After gripper 1 picks up the pipe fitting from the previous process and transfers it to the welding position of this device, positioning cylinder 3 starts working to clamp both ends of the pipe fitting. Four servo motors 11 then activate, driving the welding torch 6, connected to the sliding plate 10, to move to the desired welding point for welding. After welding is completed, the welding torch 6 resets, completing the welding process. Once welding is finished, gripper 1 picks up the pipe fitting and moves it to the next process position.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
