Description

Technical Field

[0001] This utility model relates to the field of welding processing, and in particular to a general-purpose welding platform for riveting and welding. Background Technology

[0002] Riveting is a type of electric welding. The typical welding method involves using a welding rod to penetrate the materials to be welded. It is generally used for welding relatively thick metals. Riveting is particularly suitable for joining parts made of different materials, such as plastic and metal. One part has a rivet, which is inserted into a hole in another part. Then, through the cold flow or melting of the plastic, the rivet deforms, forming a rivet head, mechanically locking the two parts together. This process is fast and economical, with the advantage of not requiring the use of rivets and screws.

[0003] A search revealed a workpiece clamping device for riveting and welding, disclosed in application number 202321164128.2, which relates to the field of welding processing technology. The device includes a riveting and welding platform. A cylinder is fixedly mounted on one side of the platform, and a driving clamping structure is fixedly mounted on the output end of the cylinder. A sliding rod is slidably mounted on the driving clamping structure, and a fixing structure is fixedly mounted on one side of the sliding rod. A positioning block is slidably mounted on the platform, and a positioning structure is fixedly mounted on the positioning block. The driving clamping structure includes a rack, which is fixedly mounted on the output end of the cylinder. This invention, through the use of a cylinder, allows two fixed plates to move closer together during cold riveting and welding, thereby clamping and fixing the welded parts on the platform. This eliminates the need for manual pressing, preventing displacement during riveting and welding, improving work efficiency, and providing convenience and speed.

[0004] According to the above patent, when welding workpieces, they are generally welded on a welding platform. During welding, the workpiece is fixed by a fixing tool to ensure the quality of the welding. Since the purpose of various parts is different, their shapes are also different. Fixing usually uses a bench vise or an electromagnet to fix the workpiece. However, this simple fixing device has high limitations. When performing angle welding, the operator still needs to hold the welding by hand and it cannot be used for multiple welding angles.

[0005] Therefore, it is necessary to propose a universal welding platform for riveting and welding to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a universal welding platform for riveting and welding, so as to solve the problem of high limitations when using bench vises and electromagnets for fixing.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a universal welding platform for riveting and welding, including a platform frame, a first electromagnet for mainly fixing the workpiece is fixedly provided on the upper right side of the platform frame, an operation box is fixedly provided on the inner side of the platform frame, and a second electromagnet is movably provided on the inner side of the operation box;

[0008] The upper end of the platform frame is provided with a central hole for the second electromagnet to move left and right. Limiting holes are provided through both ends of the operation box. Moving rods for driving the second electromagnet to move left and right are movably provided inside the two limiting holes.

[0009] A U-shaped frame is fixedly provided at the upper end of the movable rod, and the U-shaped frame is movably connected to the second electromagnet.

[0010] Preferably, two locking blocks are fixedly provided at both the upper and lower ends of the movable rod. The locking blocks have a tapered cross-section and are locked inside the limiting hole.

[0011] Preferably, two circular limiting plates are fixedly provided on the outer side of the moving rod, and the diameter of the limiting plates is larger than the width of the limiting hole.

[0012] Preferably, two limiting rings are fixedly provided on one side of the upper end of the U-shaped frame, and a rotating shaft is rotatably provided on the inner side of the two limiting rings, and the rotating shaft is fixedly connected to the end of the second electromagnet.

[0013] Preferably, a parallel rod is fixedly provided at the end of the second electromagnet away from the rotating shaft, the parallel rod contacts the U-shaped frame, and the second electromagnet is horizontally arranged.

[0014] Preferably, the rotating shaft and the limiting ring are in an interference fit.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. By using the movable second electromagnet, when welding workpieces of different sizes, the movement distance of the second electromagnet can be adjusted according to the size of the workpiece to control the contact between the first and second workpieces, thus achieving the optimal welding position. It can weld workpieces of various sizes and specifications, and has high versatility. When it is necessary to adjust the welding angle of the second workpiece, the second electromagnet is rotated, causing it to rotate around the axis of rotation to adjust the angle. It can perform welding at multiple angles, making it convenient for operators to use.

[0017] 2. By setting up parallel rods, when the workpiece is being welded, no angle assistance is required, which can ensure that the adsorption surface of the second electromagnet is always set horizontally, and ensure the absolute level of the welded workpiece for workpieces that require horizontal welding.

[0018] 3. When the moving rod moves, it directly pushes the U-shaped frame in the middle. When pushing the moving rod, it can prevent the moving rod from tilting, which would make it difficult to push the moving rod. It is convenient for the operator to move the second electromagnet, easy to use, and the overall structure is simple.

[0019] 4. Through the unique contact method of the snap-fit ​​block and the limiting hole, the moving rod can be quickly fixed when the second electromagnet needs to be fixed. The fixing method is faster than that of a bench vise or electric gripper. Furthermore, through the shape of the snap-fit ​​block, the moving rod is automatically corrected when the snap-fit ​​block is engaged, so that the moving rod is set in parallel. Thus, when the second electromagnet rotates, it can ensure that its rotation axis is parallel to that of the first electromagnet. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figure 1 - Figure 3The diagram shows a general-purpose welding platform for riveting. Riveting is a unique welding process, particularly suitable for joining parts made of different materials (e.g., plastic and metal). Plastic parts are typically small objects. One part has a rivet that extends into a hole in another part. The rivet deforms due to the cold flow or melting of the plastic, forming a rivet head that mechanically locks the two parts together. Welding can also be performed on metals of different materials. When welding metals, rivets cannot be used, and a fixing device is needed to secure the two parts to be welded together. This includes a platform frame 1, with a first electromagnet 2 fixed to the upper right side of the platform frame 1 for securing the workpiece. Welding typically involves joining two workpieces of similar size. In comparison, the larger workpiece is designated as the first workpiece, and the other as the second workpiece. Due to its weight and size, the first workpiece is a fixed component. The first workpiece is generally larger than the second workpiece. The first and second workpieces are connected by riveting and welding. The first electromagnet 2 is mainly used to fix the first workpiece. An operation box 3 is fixedly installed inside the platform frame 1. A second electromagnet 8 is movably installed inside the operation box 3. The second electromagnet 8 is mainly used to fix the second workpiece. Both the second electromagnet 8 and the first electromagnet 2 are existing technologies and will not be described in detail here. A central hole 9 is opened at the upper end of the platform frame 1 for the second electromagnet 8 to move left and right. Limiting holes 5 are opened through both ends of the operation box 3. Moving rods 4 for driving the second electromagnet 8 to move left and right are movably installed inside the two limiting holes 5.

[0026] The operator places the first workpiece on the first electromagnet 2, turns on the first electromagnet 2 to attract the first workpiece, places the second workpiece on the second electromagnet 8, turns on the second electromagnet 8 to attract the second workpiece, and controls the moving rod 4 to move inside the limiting hole 5.

[0027] A U-shaped frame 10 is fixedly provided at the upper end of the moving rod 4. Two limiting rings 11 are fixedly provided on one side of the upper end of the U-shaped frame 10. A rotating shaft 12 is rotatably provided inside the two limiting rings 11. The rotating shaft 12 is fixedly connected to the end of the second electromagnet 8. The U-shaped frame 10 and the second electromagnet 8 are movably connected through the rotating shaft 12 and the limiting rings 11. The rotating shaft 12 and the limiting rings 11 are in an interference fit to ensure that the second electromagnet 8 can be tilted and suspended at an angle when it rotates.

[0028] The moving rod 4 drives the limiting ring 11 and the rotating shaft 12 to move in parallel, so that the rotating shaft 12 drives the second electromagnet 8 to move with the moving rod 4. The second electromagnet 8 drives the second workpiece to move, so that the second workpiece is close to the first workpiece. By moving the second electromagnet 8, when welding workpieces of different sizes, the first workpiece and the second workpiece can be controlled to fit together according to the size of the workpiece itself, so as to achieve the optimal welding position. It can weld workpieces of various sizes and specifications, and has high versatility.

[0029] Two locking blocks 7 are fixed at both the upper and lower ends of the moving rod 4. The locking blocks 7 have a tapered cross-section. After the position of the second workpiece is moved, the moving rod 4 is pushed, causing the moving rod 4 to move the locking blocks 7. After the locking blocks 7 enter the limiting hole 5, the position of the moving rod 4 is fixed by pressure, thereby fixing the position of the second workpiece. The locking blocks 7 are locked inside the limiting hole 5. A parallel rod 13 is fixed at the end of the second electromagnet 8 away from the rotating shaft 12. The parallel rod 13 contacts the U-shaped frame 10. The second electromagnet 8 is horizontally set. Two circular limiting plates 6 are fixed on the outside of the moving rod 4. The diameter of the limiting plates 6 is larger than the width of the limiting hole 5. The limiting plates 6 prevent the moving rod 4 from disengaging from the limiting hole 5.

[0030] When it is necessary to adjust the welding angle of the second workpiece, rotate the second electromagnet 8 so that the second electromagnet 8 rotates around the rotating shaft 12 as the center to adjust the angle. It can perform welding at multiple angles, which is convenient for operators to use.

[0031] When the moving rod 4 moves, it directly pushes the U-shaped frame 10 in the middle. When pushing the moving rod 4, it can prevent the moving rod 4 from tilting, which would make it difficult to push the moving rod 4. It is convenient for the operator to move the second electromagnet 8, easy to use, and the overall structure is simple.
