Description

Technical Field

[0001] This utility model relates to the field of welding fixtures and jigs, specifically to an electric bed welding fixture and jig. Background Technology

[0002] As people's living standards improve, electric beds are widely used, and the bed frames of electric beds need to be welded together.

[0003] The current welding of electric beds relies on manual welding. Because manual welding requires the cooperation of multiple people, the horizontal and vertical bars of the electric bed frame are first spliced ​​together, and then a welding gun is used to perform high-temperature welding at the splicing position to fix it. The horizontal and vertical bars of the electric bed frame are relatively long and the metal material is also relatively heavy, making it extremely troublesome to transport and position them. Moreover, it is difficult to ensure that there will be no problems such as frame deformation or irregularity of the welded frame after welding. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of existing electric bed welding, which are extremely troublesome in material handling and docking positioning, and it is difficult to ensure that the frame will not be deformed or the welded frame is not regular after welding. Therefore, an electric bed welding tooling fixture is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design an electric bed welding fixture, including a support platform, a mounting plate and positioning columns. The mounting plate is fixedly connected to the top of the support platform, and the two positioning columns are fixedly installed on the inner side of the support platform. An electric bed frame push-positioning structure is provided on the inner side above the mounting plate, and an electric bed frame limiting structure is provided on the outer side above the mounting plate. Adjustable clamping structures are provided on both sides of the mounting plate.

[0007] This setup allows the mounting plate to be fixed and supported on a metal steel support platform. The mounting plate provides sufficient space for welding operations, and the flat surface above it is perfect for welding the electric bed frame structure.

[0008] Preferably, the electric bed frame push-positioning structure includes a welding plate and a sliding groove. The welding plate is fixedly connected to the inner side above the mounting plate. Multiple sliding grooves are fixedly opened at the top of the welding plate. A translation frame is slidably connected to the inner side of the multiple sliding grooves. A moving plate is fixedly connected to the top of the translation frame. A frame is fixedly connected to the outer side of the positioning column. A cylinder is fixedly installed on the outer wall of the frame.

[0009] In this setup, the welding plate is made of flat, high-temperature resistant stainless steel. The top of the welding plate serves as the surface for welding operations on the electric bed. The translation frame can move multiple horizontally positioned moving plates above the welding plate. The cylinders are equipped with a pneumatic control system and a matching power supply. The frame extending from the outside of the positioning column can support the cylinders in multiple directions. When welding the electric bed frame is required, multiple separate electric bed crossbeams and electric bed vertical beams are placed on the welding plate and manually assembled into a rough bed shape.

[0010] Preferably, the front ends of the plurality of cylinders are fixedly connected to one side of the translation frame, and the front ends of the cylinders are arranged opposite to the slide groove.

[0011] This setting activates the cylinder, which pushes multiple sliding plates at the front end to slide. As the sliding plates 44 slide outward, they also open the electric bed frame, facilitating welding positioning.

[0012] Preferably, the electric bed frame limiting structure includes an electric bed crossbeam and limiting protrusions. Multiple limiting protrusions are fixedly connected to the upper outer side of the mounting plate. The inner walls of the multiple limiting protrusions are movably connected to the electric bed crossbeam. The inner sides of the two ends of the two electric bed crossbeams are movably connected to the electric bed vertical beam. The middle inner side of the two electric bed crossbeams is movably connected to the reinforcing rod.

[0013] With this setup, the two sides of the electric bed crossbeam will be tightly pressed against the inner side of the limiting protrusion. The cylinder pushes the electric bed crossbeam to open to both sides and press it against the inner wall of the limiting protrusion. Similarly, the lateral cylinder pushes the moving plate to push the two sides of the electric bed vertical beam onto the lateral clamping block. The entire electric bed crossbeam, vertical beam and internal reinforcing rod can be placed horizontally and vertically, forming a rectangular frame structure with relatively precise and regular ends. This facilitates welding at the docking position. After welding, the electric bed frame is less prone to deformation and more square.

[0014] Preferably, the inner side of the electric bed beam abuts against the outer wall of the moving plate, and the two sides of the reinforcing rod abut against the outer wall of the transverse moving plate.

[0015] In this configuration, the inner cylinder pushes against the two moving plates to press the middle reinforcing rod for positioning.

[0016] Preferably, the adjustable clamping structure includes an adjustment block and a side clamping block. The two adjustment blocks are fixedly connected to the top ends of both sides of the mounting plate. The inner side of the adjustment block is threaded with a screw, and the ends of the two screws are movably connected to the side clamping block.

[0017] In this configuration, the screw is restricted by the adjusting blocks on both sides. When the dimensions of the electric bed vertical beams on both sides change, the screws on both sides can be rotated to push the lateral side clamping blocks at the front end to move laterally. The distance between the relatively sliding side clamping blocks will be adjusted accordingly, which can change the position where the electric bed vertical beams press outward.

[0018] Preferably, the lower end of the side clamping block is slidably connected to the top surface of the mounting plate, and the front end of the side clamping block is in close contact with the outer wall of the electric bed vertical beam.

[0019] This setting limits the welding length between the vertical beams of the electric bed by restricting the spacing between the side clamping blocks.

[0020] The electric bed welding fixture proposed in this utility model has the following advantages: the two sides of the electric bed crossbeam are closely attached to the inner side of the limiting protrusion. The cylinder pushes the electric bed crossbeam to open to both sides and press it against the inner wall of the limiting protrusion. Similarly, the lateral cylinder pushes the moving plate to push the two sides of the electric bed vertical beam onto the lateral clamping block. The inner cylinder pushes the two moving plates to press the middle reinforcing rod to achieve positioning. The entire electric bed crossbeam, vertical beam and internal reinforcing rod can be placed horizontally and vertically, and the beginning and end are relatively precise and regular to form a rectangular frame structure, which is convenient for welding gun welding at the docking position. After welding, the electric bed frame is not easy to deform and is more square. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] Example:

[0030] Please see Figure 1-6 In this embodiment, an electric bed welding fixture includes a support platform 1, a mounting plate 2, and positioning columns 3. The mounting plate 2 can be supported and fixed above the support platform 1 made of metal steel. The mounting plate 2 provides sufficient welding operation space for the welding plate 41. The flat mounting plate 2 is used for welding operations on the electric bed frame structure. The mounting plate 2 is fixedly connected to the top of the support platform 1. Two positioning columns 3 are fixedly installed on the inner side of the support platform 1. An electric bed frame pushing and positioning structure 4 is provided on the inner side of the upper part of the mounting plate 2. An electric bed frame limiting structure 5 is provided on the outer side of the upper part of the mounting plate 2. Adjustable clamping structures 6 are provided on both sides of the mounting plate 2.

[0031] The electric bed frame push-positioning structure 4 includes a welding plate 41 and sliding grooves 46. The welding plate 41 is fixedly connected to the inner side above the mounting plate 2. The welding plate 41 is made of flat, high-temperature resistant stainless steel. The top of the welding plate 41 serves as a plane for welding operations on the electric bed. Multiple sliding grooves 46 are fixedly formed on the top of the welding plate 41. A translation frame 45 can drive multiple horizontally arranged moving plates 44 to move above the welding plate 41. The translation frame 45 is slidably connected to the inner side of the multiple sliding grooves 46. The moving plates 44 are fixedly connected to the top of the translation frame 45. A frame 42 is fixedly connected to the outer side of the positioning column 3. Cylinder 43 is equipped with a pneumatic control system and a matching power supply (not shown in the figure). The frame 42 extending outward from the positioning column 3 can support cylinder 43 in multiple directions. When welding the electric bed frame, multiple separate electric bed crossbeams 51 and electric bed vertical beams 52 are placed on the welding plate 41 and first manually assembled into a rough bed shape. Then, the cylinder 43 is started, and the cylinder 43 pushes multiple moving plates 44 at the front end to slide. While the moving plates 44 slide outward, they open the electric bed frame to facilitate welding positioning. Cylinder 43 is fixedly installed on the outer wall of the frame 42.

[0032] The front ends of multiple cylinders 43 are fixedly connected to one side of the translation frame 45, and the front ends of the cylinders 43 are arranged opposite to the slide groove 46.

[0033] The electric bed frame limiting structure 5 includes an electric bed crossbeam 51 and limiting protrusions 53. Multiple limiting protrusions 53 are fixedly connected to the upper outer side of the mounting plate 2. The limiting protrusions 43 are made of multiple thin aluminum alloy plates protruding and welded to the upper edge of the mounting plate 2. The two sides of the electric bed crossbeam 51 are pressed against the inner side of the limiting protrusions 43. The cylinder 43 pushes the electric bed crossbeam 51 to open to both sides and press it against the inner wall of the limiting protrusions 53. Similarly, the lateral cylinder 43 pushes the moving plate 44 to push the two electric bed vertical beams 52 onto the lateral side clamping blocks 63, and the inner cylinder 4... 3. Pushing the two moving plates 44 relative to each other presses down the middle reinforcing rod 54 to achieve positioning. The entire electric bed's crossbeam, vertical beam, and internal reinforcing rod can be placed horizontally and vertically, forming a rectangular frame structure with relatively precise and regular ends. This facilitates welding at the docking position. After welding, the electric bed frame is less prone to deformation and more square. The inner walls of multiple limiting protrusions 43 are movably connected to the electric bed crossbeam 51. The inner sides of the two ends of the two electric bed crossbeams 51 are movably connected to the electric bed vertical beam 52. The inner side of the middle of the two electric bed crossbeams 51 is movably connected to the reinforcing rod 54.

[0034] The inner side of the electric bed crossbeam 51 abuts against the outer wall of the moving plate 44, and the two sides of the reinforcing rod 54 abut against the outer wall of the transverse moving plate 44.

[0035] The adjustable clamping structure 6 includes an adjusting block 61 and a side clamping block 63. The two adjusting blocks 61 are fixedly connected to the top of both sides of the mounting plate 2. The inner side of the adjusting block 61 is threaded with a screw 62. The screw 62 is restricted by the two adjusting blocks 61. When the size of the electric bed vertical beam 52 on both sides of the electric bed changes, the two screws 62 can be rotated to push the side clamping block 63 at the front end to move laterally. The distance between the relatively sliding side clamping blocks 63 will be adjusted accordingly, which can change the position of the electric bed vertical beam 52 pressing outward. The ends of the two screws 62 are movably connected to the side clamping blocks 63.

[0036] The lower end of the side clamping block 63 is slidably connected to the top surface of the mounting plate 2, and the front end of the side clamping block 63 is tightly attached to the outer wall of the electric bed vertical beam 52.

[0037] Working principle:

[0038] The welding fixture for electric beds is used to precisely fix the metal parts of the electric bed, ensuring that the parts are not shifted in position and have no dimensional errors during the welding process. Ultimately, it guarantees the structural strength and assembly accuracy of the electric bed and is adapted to its lifting, folding and other functional requirements. It is a fixing frame for welding the metal parts of the electric bed and solves the problems of difficult manual alignment and large welding deformation.

[0039] The mounting plate 2 can be supported and fixed on the metal steel support platform 1. The mounting plate 2 provides enough space for welding plate 41 to operate. The flat mounting plate 2 is just right for welding operations on the electric bed frame structure.

[0040] The welding plate 41 is made of flat, high-temperature resistant stainless steel. The top of the welding plate 41 is used as a plane for welding operations on the electric bed. The translation frame 45 can drive multiple horizontally set moving plates 44 to move above the welding plate 41. The cylinder 43 is equipped with a pneumatic control system and a matching power supply (not shown in the figure). The frame 42 extending outward from the positioning column 3 can support the cylinder 43 in multiple directions. When welding the electric bed frame, multiple separate electric bed crossbeams 51 and electric bed vertical beams 52 are placed on the welding plate 41. They are first manually assembled into a rough bed shape. Then the cylinder 43 is started. The cylinder 43 pushes the multiple moving plates 44 at the front end to slide. While the moving plates 44 slide outward, they open the electric bed frame to facilitate welding positioning.

[0041] The limiting protrusion 43 is made of multiple thin aluminum alloy plates protruding and welded to the upper edge of the mounting plate 2. The two sides of the electric bed crossbeam 51 will be close to the inner side of the limiting protrusion 43. The cylinder 43 pushes the electric bed crossbeam 51 to open to both sides and press against the inner wall of the limiting protrusion 53. Similarly, the lateral cylinder 43 pushes the moving plate 44 to push the two sides of the electric bed vertical beam 52 onto the lateral side clamping block 63. The inner cylinder 43 pushes the two relative moving plates 44 to press the middle reinforcing rod 54 to achieve positioning. The entire electric bed crossbeam, vertical beam and internal reinforcing rod can be placed horizontally and vertically. The beginning and end are relatively precise and regular to form a rectangular frame structure, which is convenient for welding at the docking position. After welding, the electric bed frame is not easy to deform and is more square.

[0042] The screw 62 is restricted by the adjusting blocks 61 on both sides. When the size of the electric bed vertical beams 52 on both sides of the electric bed changes, the screw 62 on both sides can be rotated to push the side clamping blocks 63 at the front end to move laterally. The distance between the relatively sliding side clamping blocks 63 will be adjusted accordingly, which can change the position where the electric bed vertical beams 52 are pressed outward.

[0043] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
