Description

Technical Field

[0001] This utility model belongs to the technical field of container door lintel welding equipment, specifically relating to a container door lintel contour welding mechanism. Background Technology

[0002] A lintel is a component in the end of a container door; common structural forms include... Figure 1 As shown, the U-shaped lintel beam 01 with an internal reinforcing plate is welded to the bent T-shaped lintel plate 02. To ensure strength and assembly efficiency, as follows... Figure 2 As shown, weld A and weld B are two continuous, full-length welds during the welding of the lintel. Therefore, a significant amount of heat is generated during the welding process. After welding is completed and cooled, the weld shrinkage causes the lintel to bulge upwards, as shown in the image. Figure 3 As shown. To ensure the lintel has the required straightness after welding and cooling, it needs to undergo reverse deformation adjustment before welding, even if the lintel forms a shape like... Figure 4 The downward convex deformation shown is used to control the straightness of the lintel after welding.

[0003] The anti-deformation adjustment before welding the lintel will cause weld seam A03 and weld seam B04 to not be a straight line during the welding process, but rather a downward-convex arc. To achieve automated welding of these two seams, the automatic welding equipment needs to be able to weld along this arc-shaped weld bead, ensuring a beautiful weld formation while achieving high quality and efficiency. Traditional welding processes use laser positioning and three-coordinate positioning welding to achieve this arc-shaped weld bead. Laser positioning is expensive and requires highly skilled workers; three-coordinate positioning welding requires pre-programming, the weld formation quality is affected by the program settings, and the operation and control are relatively complex.

[0004] Based on this, this application proposes a low-cost, relatively simple structure, and easy-to-operate container lintel contour welding mechanism to solve the welding problem of the arc-shaped weld bead of the lintel. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a container lintel contour welding mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A container lintel contour welding mechanism includes a support frame, with a liftable welding adjustment component on each side of the support frame.

[0013] Preferably, the welding torch disengagement assembly includes a welding torch disengagement cylinder, wherein the piston rod of the welding torch disengagement cylinder can extend and press against a corresponding first imitation plate.

[0014] Preferably, the clamping assembly includes a limiting bolt fixedly disposed on the first imitation plate, the bolt head end of the limiting bolt passing outward through the second imitation plate, and a compression spring sleeved on the limiting bolt, the compression spring being located between the second imitation plate and the bolt head of the limiting bolt;

[0023] The beneficial effects of this utility model are:

[0024] (1) Using the welding mechanism of this utility model, the welding gun is moved in a downward convex arc shape to achieve the conformal welding of the arc weld after the convex deformation of the lintel. It can adapt to lintel components with different deformation amounts. When the thickness, material and shape of the lintel component change, the extension of the piston rod of the lifting cylinder will change with the deformation amount when the lintel component is reversed during the welding process, so as to ensure the final forming quality and ensure that different models of lintel components have the same welding quality after welding.

[0043] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0044] like Figures 5-6 As shown, a container door lintel contour welding mechanism includes a support 1, and a liftable welding adjustment component is provided on each side of the support 1.

[0045] The welding adjustment assembly includes a slide block 2 that slides vertically with the bracket 1, and a first imitation plate 3 and a second imitation plate 4 disposed on the slide block 2. The first imitation plate 3 is located on the inner side, and the two second imitation plates 4 are located on the outer side. The top end of the first imitation plate 3 is fixedly connected to the bottom end of the slide block 2, and the bottom end of the first imitation plate 3 is provided with a first conforming roller 5 for pressing against the top surface of the U-shaped lintel beam 01. The top end of the second imitation plate 4 rotates with the slide block 2. Specifically, the top end of the second imitation plate 4 rotates with the slide block 2 via a first rotating shaft 45, and the bottom end of the second imitation plate 4 is provided with a second conforming roller 6 for pressing against the outer wall of the U-shaped lintel beam 01. Both the first conforming roller 5 and the second conforming roller 6 can roll along the length of the lintel.

[0046] One of the welding adjustment components has a second imitation plate 4 equipped with a first welding torch 7 for welding the arc-shaped weld bead that forms weld seam A03, and another welding adjustment component has a second imitation plate 4 equipped with a second welding torch 8 for welding the arc-shaped weld bead that forms weld seam B04.

[0047] In this application, the first welding torch 7 is mounted on the second imitation plate 4 of one of the welding adjustment components via the first connector 71, and the second welding torch 8 is mounted on the second imitation plate 4 of another welding adjustment component via the second connector 81. When the first imitation roller 5 presses on the top surface of the U-shaped lintel beam 01 and the second imitation roller 6 presses on the corresponding outer wall of the U-shaped lintel beam 01, the welding point of the first welding torch 7 is located at the welding position of the arc-shaped weld bead forming weld A03, and the welding point of the second welding torch 8 is located at the welding position of the arc-shaped weld bead forming weld B04.

[0048] Preferably, the slide block 2 is provided with a linear slider 21, and the two sides of the bracket 1 are provided with vertical linear guide rails 11 that slide vertically with the corresponding linear slider 21.

[0049] The top of the slide block 2 is connected to the piston rod end of the lifting cylinder 22, which is fixedly mounted on the bracket 1.

[0050] Specifically, in this application, the bracket 1 has an inverted U-shaped structure, the vertical linear guide rail 11 is set on the left and right outer surfaces of the bracket 1, and the lifting cylinder 22 is fixedly set on the corresponding side wall of the bracket 1.

[0051] Preferably, the second imitation plate 4 is provided with a welding gun release assembly for driving the second imitation roller 6 away from the corresponding outer wall of the U-shaped lintel beam 01 and a pressing assembly for driving the second imitation roller 6 to press against the corresponding outer wall of the U-shaped lintel beam 01.

[0052] Preferably, the welding torch disengagement assembly includes a welding torch disengagement cylinder 41, the piston rod of which can extend and press against the corresponding first imitation plate 3.

[0053] Preferably, the clamping assembly includes a limiting bolt 42 fixedly disposed on the first imitation plate 3, the bolt head end of the limiting bolt 42 passing outward through the second imitation plate 4, and a compression spring 43 sleeved on the limiting bolt 42, the compression spring 43 being located between the second imitation plate 4 and the bolt head of the limiting bolt 42;

[0054] The second imitation plate 4 is provided with a vertical waist-shaped hole 44 through which the adaptation limiting bolt 42 passes.

[0055] When the piston rod of the welding torch disengages from the cylinder 41 and extends to press against the corresponding first imitation plate 3, the second imitation plate 4 will overcome the elastic force of the compression spring 43 and rotate upward around the first rotating shaft 45, thereby driving the second imitation roller 6 away from the corresponding outer wall of the U-shaped lintel beam 01, and thus causing the welding torch to move away from the corresponding arc weld bead. When the piston rod of the welding torch disengages from the cylinder 41 and retracts to its original position, under the elastic force of the compression spring 43, the second imitation plate 4 rotates downward around the first rotating shaft 45, thereby driving the second imitation roller 6 to press against the corresponding outer wall of the U-shaped lintel beam 01, and thus causing the welding torch to be aligned with the corresponding arc weld bead.

[0056] Preferably, a walking motor 12 is provided on the top of the bracket 1, and the output end of the walking motor 12 is connected to the drive gear 13;

[0057] The bracket 1 is provided with a limiting slider 14.

[0058] When using the welding mechanism of this application, it needs to be adapted to an automatic lintel welding equipment. This automatic lintel welding equipment is a common, existing device, comprising a frame 9, a worktable 91 for placing the lintel, a horizontal guide rail 92 that slides horizontally with the limit slider 14, a rack 93 meshing with the drive gear 13, and a deflection cylinder 94 and a deflection pressure plate 95 that press down on the lintel to create a deflection. The welding mechanism of this application moves along the horizontal guide rail 92 to perform the welding operation. The walking motor 12 and drive gear 13 in this application are used to drive the welding mechanism to move along the horizontal guide rail 92.

[0059] Preferably, the bracket 1 is provided with a motor disengagement assembly for driving the walking motor 12 to rotate so that the walking drive fails.

[0060] Preferably, the motor disengagement assembly includes a motor disengagement cylinder 15, which is fixedly mounted on the top of the support 1 via a cylinder bracket 151. A rotating seat 152 is provided at the top of the cylinder bracket 151. The cylinder bracket 151 has an L-shaped structure, with its horizontal plate fixedly connected to the support 1. The motor disengagement cylinder 15 is mounted on the vertical plate of the cylinder bracket 151, and the rotating seat 152 is located at the top of the vertical plate of the cylinder bracket 151.

[0061] The walking motor 12 is fixedly mounted on the motor bracket 121. The top end of the motor bracket 121 is rotatably engaged with the rotating seat 152 via the second rotating shaft 122. The motor bracket 121 has an L-shaped structure. The horizontal plate of the motor bracket 121 is fixedly connected to the walking motor 12. The second rotating shaft 122 is located at the top end of the vertical plate of the motor bracket 121.

[0062] After the motor extends out of the piston rod of the cylinder 15, it can drive the motor bracket 121 to drive the walking motor 12 to rotate around the second rotating shaft 122.

[0063] The bracket 1 is provided with a through hole for the output shaft of the walking motor 12 to pass through.

[0064] In this application, by setting the motor disengagement component, it is possible to control the meshing and engagement of the drive gear 13 and the rack 93, as well as to disengage the drive gear 13 and the rack 93.

[0065] Preferably, roller assemblies 16 are provided at the inner ends of the two side walls of the bracket 1. A roller linear slider 96 that cooperates with the roller assembly 16 is provided on the frame 9.

[0066] A container door lintel contour welding mechanism, the specific implementation of which is as follows:

[0067] The welding mechanism described in this application needs to be adapted for use with automatic lintel welding equipment, which is an existing, general-purpose equipment. Figures 7-9 As shown, it includes a frame 9, on which a worktable 91 for placing the lintel is provided, a horizontal guide rail 92 that is horizontally linearly slidable with the limit slider 14, a rack 93 that meshes with the drive gear 13, a roller linear slider 96 that cooperates with the roller assembly 16, an anti-deformation cylinder 94 that presses down on the lintel to form an anti-deformation state, and an anti-deformation pressure plate 95. In addition, a lifting mechanism 97 for lifting the lintel is provided at the bottom of the worktable 91.

[0068] When using the welding mechanism described in this application:

[0069] Step 1: Place the T-shaped lintel panel 02 and the U-shaped lintel beam 01 onto the workbench 91 in sequence, and fix and limit them through the positioning mechanisms on the workbench 91. In this step, the T-shaped lintel panel 02 and the U-shaped lintel beam 01 can be pre-spot welded together, or they can be directly placed on the workbench 91 for fixing and limiting. Since the welding equipment for automatic lintel welding is existing general equipment, the positioning mechanism that plays the role of fixing and limiting can be implemented using existing technology, and its specific structure and implementation method will not be described in detail here.

[0070] Step 2: After positioning is completed, drive the anti-deformation cylinder 94 to drop the anti-deformation pressure plate 95, and apply downward pressure to the middle position of the lintel to form an anti-deformation state;

[0071] Step 3: Control the welding mechanism of this application to move to the starting position. At this time, the welding torch disengages from the piston rod of the cylinder 41 and extends, so that the second imitation plate 4 is in a state away from the first imitation plate 3.

[0072] For the welding adjustment assembly on the left, the piston rod of the driving lifting cylinder 22 extends, causing the slide 2, the first imitation plate 3, the second imitation plate 4, the first imitation roller 5, and the second imitation roller 6 to fall down until the first imitation roller 5 presses on the top surface of the U-shaped lintel beam 01; then the piston rod of the driving welding torch disengages from the cylinder 41 and retracts to reset. Under the elastic force of the compression spring 43, the second imitation plate 4 rotates downward around the first rotating shaft 45, thereby causing the second imitation roller 6 to press on the corresponding outer wall of the U-shaped lintel beam 01, so that the first welding torch 7 is aligned with the corresponding arc weld bead;

[0073] For the welding adjustment assembly on the right, the same adjustment method is used to align the second welding torch 8 with the corresponding arc weld bead;

[0074] At this time, the first welding torch 7 and the second welding torch 8 are at the welding starting point, completing the pre-welding preparation work;

[0075] Step 4: After the preparation work is completed, the walking motor 12 is started, and the welding mechanism of this application moves along the horizontal guide rail 92 to start the automatic welding process;

[0076] During the welding process, the extension of the piston rod of the lifting cylinder 22 changes with the amount of deformation when the lintel component undergoes reverse deformation, so that the first contouring roller 5 is always pressed on the top surface of the U-shaped lintel beam 01, and the welding points of the first welding gun 7 and the second welding gun 8 move along the downward convex arc weld bead, thereby adapting to the arc deformation trajectory of the weld when the lintel is in a downward deformation state, thus automatically completing the contouring automated welding process for this weld bead; in addition, during the welding process, the compression spring 43 always presses the second contouring roller 6 on the corresponding outer wall of the U-shaped lintel beam 01;

[0077] Step 5: After welding is completed, the welding torch extends from the piston rod of cylinder 41, so that the second imitation plate 4 is in a state away from the first imitation plate 3. Even if the welding torch is away from the weld position, the piston rod of lifting cylinder 22 retracts, driving the slide 2, the first imitation plate 3, the second imitation plate 4, the first imitation roller 5, and the second imitation roller 6 to move upward and reset. Then, the anti-deformation cylinder 94 is controlled to move the anti-deformation pressure plate 95 upward and reset. Then, the lifting mechanism 97 lifts the welded lintel and transports the welded lintel component to the next platform.

[0078] Step Six: After the lintel leaves the workbench 91, control the welding mechanism of this application to reset to the starting position, preparing for the next welding process. One method for resetting the welding mechanism is to drive the travel motor 12 in reverse, achieving a return reset through the meshing connection of the drive gear 13 and rack 93. Another method is to disengage the piston rod of the drive motor from the cylinder 15 and extend it, allowing the motor bracket 121 to drive the travel motor 12 to rotate around the second rotating shaft 122, disengaging the drive gear 13 from the rack 93, and manually resetting the welding mechanism of this application to the starting position.

[0079] The welding equipment for automatic welding of door lintels used in conjunction with the welding mechanism of this utility model is existing general equipment, which is shown schematically in the accompanying drawings.

[0080] The accompanying drawings of this utility model show one structure of a lintel. This utility model can be used for contour welding of lintels of various specifications.

[0081] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, they are not intended to limit the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the protection scope of the present utility model.
