Description

Technical Field

[0001] This utility model relates to the technical field of welding positioning devices, and in particular to a flip-type welding positioning device for bed frame production. Background Technology

[0002] In the field of bed frame manufacturing, welding is a crucial process that directly determines the structural strength, stability, and overall quality of the bed frame. With consumers' increasing demands for bed frame quality and the intensification of market competition, how to efficiently and accurately complete bed frame welding has become a core issue that many bed frame manufacturers urgently need to address. Traditional bed frame welding methods often employ fixed positioning devices. In this mode, workers need to weld various components of the bed frame at specific locations. However, with the continuous changes in market demand and the increasing quality requirements of consumers for bed frames, the limitations of traditional fixed welding positioning devices have gradually become apparent. Fixed positioning devices cannot allow the welding torch to approach the weld at the most suitable angle. For welds in some special locations, such as corners or inclined surfaces inside the bed frame, workers need to use unconventional welding postures, which not only increases the welding difficulty but also easily leads to welding defects. Therefore, corresponding improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to provide a flip-type welding positioning device for bed frame production, so as to solve the problem mentioned in the background art that the existing welding positioning devices for bed frame production have a single function, are inconvenient to flip and use, and affect the subsequent welding efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a flip-up welding positioning device for bed frame production, comprising a base platform and support legs, wherein support legs are fixed on both sides of the top of the base platform, and one end of each support leg is connected to a limit roller; The top of each limiting roller is connected to a support guide ring and a support wheel ring. Both the support guide ring and the support wheel ring have grooves inside. The limiting rollers extend into the grooves. A flipping and rotating component is provided on one side of the support guide ring. An internal frame is fixed inside the support guide ring and the support wheel ring. A positioning and clamping mechanism is provided between the internal frames. A feeding mechanism is provided between the internal frames.

[0005] Furthermore, the flipping and rotating assembly includes a drive motor disposed on the outer side of the base, and a transmission sprocket is fixed to the output shaft end of the drive motor. A rotating wheel is fixed to the outer side of the support guide ring, and a transmission chain is disposed inside the rotating wheel. Both ends of the transmission chain are fixed with fixing members, and one end of the fixing member is connected to a fixing plate. The fixing plate is fixed to the rotating wheel.

[0006] Furthermore, the transmission chain is coiled in the rotating rim and fits tightly against the inner wall of the rotating rim, and the rotating rim meshes with the transmission sprocket.

[0007] Furthermore, the positioning and clamping mechanism includes a connecting plate, which is disposed and fixed between the inner frame. A cylinder is connected to one side of the connecting plate, and one end of the cylinder passes through the connecting plate and is fixed with a positioning clamping plate. Guide posts are connected to both ends of the outer side of the positioning clamping plate, and a connecting plate is connected between the guide posts.

[0008] Furthermore, the built-in frame has a rectangular frame structure, and the built-in frames are connected by overlapping columns.

[0009] Furthermore, the feeding mechanism includes a support plate, which is connected between the inner frames. A lead screw linear module is connected to the top of the support plate, and a feeding plate is connected to the top of the lead screw linear module. Guide members are connected to both sides of the feeding plate. The linear screw module includes a servo motor, a one-way screw, and a threaded block. The servo motor is fixed to the top of the support plate. One end of the servo motor is connected to the one-way screw, and the one-way screw is threadedly connected to the threaded block, which is connected to the feeding plate.

[0010] Furthermore, the guide includes a guide rail fixed to the top of the support plate, and a slider is slidably connected to the outside of the guide rail, the slider being connected to one side of the feeding plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the flip-type welding positioning device for bed frame production not only has the function of positioning and flipping, but also has the function of self-feeding of bed boards, so as to improve its processing and welding efficiency. The positioning clamps are moved horizontally by a cylinder, and the guide column moves in the connecting plate to limit and guide the movement of the positioning clamps. The two positioning clamps are brought close together to clamp and position the bed frame and bed board, so as to facilitate a stable welding process later. Then, the drive motor drives the transmission sprocket to rotate. The transmission sprocket and the transmission chain mesh with each other, so that the transmission chain rotates and the rotating wheel ring and the support guide ring rotate synchronously. This allows the positioned bed board to rotate 360 ​​degrees. Welders can always maintain the best welding posture to operate, so that the width, depth and reinforcement of the weld are more uniform, thus ensuring welding uniformity and improving welding quality. By utilizing the linear screw module, the feeding plate moves horizontally and is guided by the guide components to limit and guide the plate to be welded. This allows the plate to be positioned and clamped between the positioning and clamping mechanisms. The operation is convenient, replacing manual feeding and making it more efficient and convenient.

Please refer to the details. Figure 1 , Figure 2 , Figure 4 , Figure 6 The drive motor 6 drives the transmission sprocket 8 to rotate. The transmission sprocket 8 meshes with the transmission chain 11, which in turn causes the transmission chain 11 to rotate. The transmission chain 11 is fixed in the rotating wheel rim 5, so that the rotating wheel rim 5 and the support guide ring 4 rotate synchronously. The limit roller 3 guides and supports the rotation of the support guide ring 4. Then, in conjunction with the built-in frame 7 and the overlapping column 701, the support wheel rim 12 rotates synchronously. The positioned bed board can then be flipped to meet the different processing requirements of the welding process. The support guide ring 4 and the support wheel ring 12 are fixed with built-in frames 7, and positioning clamping mechanisms 9 are provided between the built-in frames 7.

Please refer to the details. Figure 1 , Figure 2 , Figure 3In this embodiment, the built-in frames 7 are overlapped by overlapping columns 701 to form an integral support structure between the support guide ring 4 and the support wheel ring 12. Then, the bed frame and bed board are placed between the positioning and clamping mechanisms 9. The driving cylinder 902 pushes the positioning clamping plate 903 to move horizontally and is limited and guided by the guide column 904 until the positioning clamping plate 903 clamps and positions the bed board to ensure the stable progress of the subsequent welding process.
