Description

Technical Field

[0001] This application relates to the field of stainless steel plate production, and more specifically, to a positioning welding apparatus for stainless steel plate production. Background Technology

[0002] Stainless steel welding is suitable for stainless steel welding electrodes used in manual arc welding. When welding stainless steel plates, an alignment device is required to fix the position of the stainless steel plate.

[0003] While current steel plate welding alignment devices can adaptively adjust the weld width according to the thickness of the plate, they cannot meet most welding needs. Although the increase in weld width is based on the increase in plate thickness, it is not a simple 1:1 increase, but is determined by various welding process parameters. In other words, when the thickness of the plate changes, the weld width needs to be determined according to the actual welding process parameters, and the weld width does not change by the same amount as the thickness of the plate.

[0004] Chinese patent application CN202322537848.5 discloses a stainless steel plate welding alignment device, including a base, a moving platform, and an alignment mechanism. The alignment mechanism includes a U-shaped plate, a clamping plate, a U-shaped frame, an electric push rod, and a positioning plate. Two moving platforms are symmetrically mounted on the base, and the alignment mechanism is fixed on the moving platforms. A servo motor drives a bidirectional threaded rod to rotate, causing the two moving platforms to move the two alignment mechanisms in opposite directions to adjust the distance between them. With the help of scale lines, the weld seam of the two steel plates can be precisely positioned to ensure welding accuracy. The alignment mechanism is suitable for fixing steel plates of different thicknesses and has a wide range of applications.

[0005] The above solution has the following shortcomings: When using it, the clamping plate is used to clamp the steel plate by moving inward, but it is not easy to limit the top of the stainless steel plate. Due to the elasticity and flexibility of the stainless steel plate itself, the steel plate will shift, which will affect the quality of the butt welding and reduce the practicality of the device. Utility Model Content

[0006] To overcome the above shortcomings, this application provides a butt welding device for stainless steel plate production, which aims to improve the problem that it is not easy to limit the top of the stainless steel plate. Due to the elasticity and flexibility of the stainless steel plate itself, the plate may shift, thereby affecting the quality of the butt welding and reducing the practicality of the device.

[0007] This application provides a welding device for stainless steel plate production, including a flipping structure and a butt welding structure. The flipping structure includes a worktable, a rotating frame, and a rotating assembly. The rotating frame is connected to the rotating assembly, and the rotating assembly is rotatably connected to the worktable. The butt welding structure includes two electric push rods, a sliding frame, an adjusting screw, a clamping plate, and a limiting assembly. The two electric push rods are installed opposite each other in the rotating frame. The movable ends of the two electric push rods are fixedly connected to the sliding frame. The sliding frame is slidably connected to the rotating frame. The adjusting screw is threadedly connected to the sliding frame and rotatably connected to the clamping plate. The limiting assembly is connected to the clamping plate.

[0008] In one specific implementation, the rotating assembly includes a handwheel, a first rotating shaft, and a second rotating shaft. The first rotating shaft is fixedly connected to the handwheel, and the first rotating shaft and the second rotating shaft are respectively fixedly connected to both sides of the rotating frame. Both the first rotating shaft and the second rotating shaft are rotatably connected to the worktable.

[0009] In the above implementation process, the handwheel, the first rotating shaft and the second rotating shaft can be set to easily drive the rotating frame to rotate, thereby facilitating the flipping of the stainless steel plate and making it convenient to weld the two sides of the stainless steel plate.

[0010] In one specific implementation, a locking assembly is provided on one side of the workbench. The locking assembly includes a slide rod, a spring, and a cross plate. Two slide rods are arranged opposite each other on one side of the cross plate. The slide rods are slidably connected to the workbench and engaged with the rotating frame. The two ends of the spring are fixedly connected to the cross plate and the workbench, respectively.

[0011] In the above implementation process, the setting of slide bar, spring and cross plate can easily lock the position of the rotating frame and prevent the stainless steel plate from shifting during welding.

[0012] In one specific implementation, a slot is provided on one side of the rotating frame, and the slide rod engages with the slot.

[0013] In the above implementation process, the sliding rod is engaged with the slot, which facilitates the connection between the sliding rod and the rotating frame.

[0014] In one specific implementation, the limiting component includes an L-shaped limiting plate, a pull plate, a fixing screw, and screw holes. The L-shaped limiting plate is slidably connected to both sides of the clamping plate. The pull plate is fixedly connected to the L-shaped limiting plate. A plurality of screw holes are evenly provided on one side of the L-shaped limiting plate. The clamping plate is fixed to the L-shaped limiting plate through the threaded connection of the fixing screw and the screw holes.

[0015] In the above implementation process, the L-shaped limiting plate, pull plate, fixing screw and screw hole can be set to conveniently limit the stainless steel plates of different widths.

[0016] In one specific implementation, a bearing is embedded on one side of the clamping plate, and one end of the adjusting screw is engaged with the inner ring of the bearing.

[0017] In the above implementation process, by adjusting one end of the screw to cooperate with the inner ring of the bearing, it is possible to reduce wear and tear, and at the same time, it is convenient to adjust the screw to drive the clamping plate to move.

[0018] In one specific implementation, a connecting rod is fixedly connected to one side of the clamping plate, and the connecting rod is slidably connected to the sliding frame.

[0019] In the above implementation process, the sliding connection between the connecting rod and the sliding frame makes it easy to limit the movement of the clamping plate.

[0020] Compared with the prior art, the beneficial effects of this application are as follows: the setting of the worktable, rotating frame and rotating assembly can easily drive the stainless steel plate to flip over, which facilitates welding processing on both sides of the stainless steel plate. The setting of two electric push rods, sliding frame, adjusting screw, clamping plate and limiting assembly can easily fix the stainless steel plate in the horizontal and vertical directions respectively, avoiding the stainless steel plate from shifting during welding processing.

Detailed Implementation

[0030] Please see Figure 1 , Figure 2 and Figure 3 The flipping structure 10 includes a worktable 110, a rotating frame 120 and a rotating assembly 130. The rotating frame 120 is connected to the rotating assembly 130, and the rotating assembly 130 is rotatably connected to the worktable 110.

[0031] In a specific configuration, the rotating assembly 130 includes a handwheel 131, a first rotating shaft 132, and a second rotating shaft 133. The first rotating shaft 132 is fixedly connected to the handwheel 131, and the first rotating shaft 132 and the second rotating shaft 133 are respectively fixedly connected to both sides of the rotating frame 120. Both the first rotating shaft 132 and the second rotating shaft 133 are rotatably connected to the worktable 110. The handwheel 131, the first rotating shaft 132, and the second rotating shaft 133 facilitate the rotation of the rotating frame 120, thereby facilitating the flipping of the stainless steel plate and making it convenient to weld the two sides of the stainless steel plate.

[0032] In the specific configuration, a locking assembly 140 is provided on one side of the workbench 110. The locking assembly 140 includes a slide rod 141, a spring 142, and a horizontal plate 143. Two slide rods 141 are arranged opposite each other on one side of the horizontal plate 143. The slide rods 141 are slidably connected to the workbench 110 and are engaged with the rotating frame 120. The two ends of the spring 142 are fixedly connected to the horizontal plate 143 and the workbench 110, respectively. The arrangement of the slide rods 141, springs 142, and horizontal plate 143 can easily lock the position of the rotating frame 120 and prevent the stainless steel plate from shifting during welding.

[0033] In a specific configuration, a slot 150 is provided on one side of the rotating frame 120, and the slide rod 141 is engaged with the slot 150. The engagement of the slide rod 141 with the slot 150 facilitates the connection between the slide rod 141 and the rotating frame 120.

[0034] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The docking structure 20 includes two electric push rods 210, a sliding frame 220, an adjusting screw 230, a clamping plate 240, and a limiting component 250. The two electric push rods 210 are installed opposite each other in the rotating frame 120. The sliding frame 220 is fixedly connected to the movable end of each of the two electric push rods 210. The sliding frame 220 is slidably connected to the rotating frame 120. The adjusting screw 230 is threadedly connected to the sliding frame 220. The adjusting screw 230 is rotatably connected to the clamping plate 240. The limiting component 250 is connected to the clamping plate 240.

[0035] In a specific configuration, the limiting component 250 includes an L-shaped limiting plate 251, a pull plate 252, a fixing screw 253, and screw holes 254. The clamping plate 240 is slidably connected to both sides of the L-shaped limiting plate 251. The pull plate 252 is fixedly connected to the L-shaped limiting plate 251. Several screw holes 254 are evenly provided on one side of the L-shaped limiting plate 251. The clamping plate 240 is fixed to the L-shaped limiting plate 251 through the threaded connection of the fixing screw 253 and the screw holes 254. The configuration of the L-shaped limiting plate 251, the pull plate 252, the fixing screw 253, and the screw holes 254 facilitates the limiting of stainless steel plates of different widths.

[0036] In the specific setup, a bearing is embedded on one side of the clamping plate 240, and one end of the adjusting screw 230 is engaged with the inner ring of the bearing. By engaging one end of the adjusting screw 230 with the inner ring of the bearing, wear can be easily reduced, and the adjusting screw 230 can be easily used to drive the clamping plate 240 to move.

[0037] In a specific configuration, a connecting rod 260 is fixedly connected to one side of the clamping plate 240. The connecting rod 260 is slidably connected to the sliding frame 220. The slidable connection between the connecting rod 260 and the sliding frame 220 facilitates the limitation of the movement of the clamping plate 240.

[0038] The working principle of this stainless steel plate production alignment welding device is as follows: When using the stainless steel plate production alignment welding device, according to the width of the plate to be welded, the user pulls two pull plates 252 in sequence to drive the L-shaped limiting plate 251 to slide laterally inside the clamping plate 240. The fixing screw 253 engages with screw holes 254 at different positions to fix the plate, thereby adjusting the distance between the two L-shaped limiting plates 251. Two stainless steel plates are placed in the sliding frame 220 respectively. By rotating the adjusting screw 230, the clamping plate 240 is driven to move along the connecting rod 260. The clamping plate 240, in conjunction with the inner wall of the sliding frame 220, clamps the stainless steel plates. Two sets of electric push rods 210 push the sliding frame 220 to slide along the rotating frame 120, causing the two stainless steel plates to... The stainless steel plates are aligned, and the top surface of the stainless steel plates is welded using an external welding machine. By pulling the horizontal plate 143, the slide rod 141 is moved, and the spring 142 is stretched, so that the slide rod 141 is released from the slot 150. The handwheel 131 is turned to drive the rotating frame 120 to rotate around the worktable 110 through the first rotating shaft 132 and the second rotating shaft 133, and then reset by the spring 142, so that the slide rod 141 is re-engaged with the slot 150, which facilitates fixing the position of the rotating frame 120. At this time, the other side of the stainless steel plate is welded. After the double-sided welding is completed, the locking component 140 is released and the rotating frame 120 is reversed to the initial position. The adjusting screw 230 is rotated in the opposite direction to loosen the clamp and reset the electric push rod 210, so that the welded product can be taken out.

[0039] It should be noted that the specific model and specifications of the electric actuator 210 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0040] The power supply and principle of the electric actuator 210 are clear to those skilled in the art and will not be described in detail here.

[0041] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
