Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and more specifically, to a positioning system and process for welding ship components. Background Technology

[0002] Shipbuilding is a typical complex and heavy industrial field. Welding is one of the core processes in shipbuilding. During the ship welding process, large steel structure components such as hull plates, decks, ribs, and T-sections need to be assembled and positioned according to the design precision requirements before welding is carried out.

[0003] The existing technology has the following shortcomings when used: 1. When the workpiece surface is uneven or there is an angular deviation, the traditional gripper is difficult to automatically adjust its posture to achieve uniform fit, which can easily cause the pressure of the gripper to be too concentrated in one place, resulting in the workpiece being pressed with indentations or even deformed in a local position.

[0004] 2. Since most existing shock-absorbing structures are directly installed on the clamping surface of the clamping equipment, the shock-absorbing components will absorb part of the clamping force, which leads to a decrease in the clamping stability of the clamping equipment for materials.

[0005] Therefore, a positioning system and process for welding ship components are needed to solve the above problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a positioning system and process for welding ship components, which can solve the problem of a positioning system and process for welding ship components.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] The application is as follows:

[0009] A positioning system for welding ship components includes a placement platform, the inner wall of which is provided with a plurality of limiting grooves, the interior of which is provided with a positioning structure, and the outer wall of which is provided with a shock-absorbing structure.

[0010] The positioning structure includes a connecting plate, the outer wall of which is slidably connected to the inner wall of the placement platform. A first connecting rod is rotatably connected to the inner wall of the connecting plate. An L-shaped push rod is hinged to the outer wall of the first connecting rod away from the connecting plate. A shaped gripper is rotatably connected to the outer wall of the L-shaped push rod. The inner wall of the shaped gripper is provided with anti-slip texture. A second connecting rod is hinged to the outer wall of the shaped gripper. Both the outer walls of the L-shaped push rod and the second connecting rod are hinged to fixed shafts.

[0011] As a preferred technical solution of this application, the shock-absorbing structure includes a support block, the outer wall of which is fixedly connected to the top outer wall of a connecting plate. A plurality of inclined push blocks are fixedly connected to the outer wall of the support block. An inclined top block is slidably connected to the outer wall of each inclined push block. A pressure spring is fixedly connected to the outer wall of the inclined top block. A fixed outer shell is fixedly connected to the top outer wall of the inclined top block. A shock-absorbing plate is slidably connected to the inner wall of the fixed outer shell. A shock-absorbing assembly is provided on the inner wall of the fixed outer shell.

[0012] As a preferred technical solution of this application, the shock absorption assembly includes a positioning seat, a first support rod rotatably connected to the outer wall of the positioning seat, a positioning shaft hinged to the outer wall of the first support rod away from the positioning seat, a second support rod hinged to the outer wall of the positioning shaft, a connecting seat rotatably connected to the outer wall of the second support rod away from the positioning shaft, a connecting block fixedly connected to the outer wall of the positioning shaft, and a spring damper fixedly connected to the outer wall of the connecting block.

[0013] As a preferred technical solution of this application, a support base is fixedly connected to the bottom outer wall of the placement platform, and an electric push rod is fixedly connected to the bottom inner wall of the support base. The output end of the electric push rod is fixedly connected to the outer wall of the connecting plate.

[0014] As a preferred technical solution of this application, the outer wall of the irregular-shaped gripper is slidably connected to the inner wall of the placement table, the irregular-shaped gripper and the L-shaped push rod are detachably connected, and can be replaced with a flat gripper or a V-shaped gripper, and the outer wall of the fixed shaft is fixedly connected to the inner wall of the placement table.

[0015] As a preferred technical solution of this application, the outer wall of the L-shaped push rod is slidably connected to the inner wall of the placement platform, and the outer wall of the second connecting rod is slidably connected to the inner wall of the placement platform.

[0016] As a preferred technical solution of this application, the outer wall of the support block is slidably connected to the inner wall of the placement platform, and the outer wall of the inclined push block is slidably connected to the inner wall of the placement platform.

[0017] As a preferred technical solution of this application, the outer wall of the inclined top block is slidably connected to the inner wall of the placement platform, and the outer wall of the pressure spring is fixedly connected to the inner wall of the placement platform.

[0018] As a preferred technical solution of this application, the outer wall of the fixed shell is slidably connected to the outer wall of the placement platform, and the outer wall of the shock-absorbing plate is fixedly connected to the outer wall of the connecting seat.

[0019] A positioning process for welding ship components includes the following steps:

[0020] Step 1: Equipment debugging and adaptation: According to the specifications and shape of the ship parts to be welded, replace the irregular jaws with suitable flat jaws or V-shaped jaws, check the connection status of each component of the positioning structure and shock absorption structure, and ensure that the equipment operates smoothly.

[0021] Step 2: Workpiece placement and positioning: Place the ship component to be welded on the damping plate of the placement table, and activate the electric push rod inside the support base. The electric push rod pushes the connecting plate to slide and move on the inner wall of the placement table.

[0022] Step 3: Adaptive clamping and fixing: During the movement of the connecting plate, the first connecting rod is driven to move, and in conjunction with the fixed shaft limit, the L-shaped push rod is driven to move in conjunction with the second connecting rod, so that the irregular-shaped gripper fits against the outer wall of the ship component. The anti-slip texture achieves stable clamping and fixing of the workpiece, and completes the precise positioning of the workpiece.

[0023] Step 4: Welding vibration reduction and protection: During the welding operation, the vibration generated by the workpiece is transmitted to the damping plate, which drives the connecting seat, the second support rod and the first support rod to swing in linkage. This, together with the spring damper on the outside of the positioning shaft, achieves primary vibration reduction. At the same time, the support block slides with the connecting plate, which drives the inclined push block to squeeze the inclined top block and the pressure spring, achieving secondary buffering and vibration reduction to offset the welding vibration.

[0024] Step 5: Part Reset: After the ship component welding is completed, control the electric push rod to reset, causing the positioning structure to spring back as a whole. The irregular-shaped gripper releases the workpiece, removes the welded ship component, and completes the single welding positioning operation.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. By using a connecting plate and irregularly shaped grippers, the problem of traditional grippers being unable to automatically adjust their posture to achieve uniform fit when the workpiece surface is uneven or has angular deviation is solved. This can easily cause the pressure of the grippers to be too concentrated in one place, resulting in indentations or even deformation of the workpiece in a localized area.

[0027] 2. By using inclined push blocks and damping plates, the problem of reduced clamping stability of the clamping equipment for materials is solved, as most existing damping structures are directly placed on the clamping surface of the clamping equipment and the damping components absorb part of the clamping force.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0038] In the description of this invention, it should be noted that the terms "upper" and "lower," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed when in use, or the orientation or positional relationship commonly understood by those skilled in the art. These terms are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. In addition, the terms "first" and "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0039] Example:

[0040] like Figure 1-4 As shown, the positioning system for welding ship components proposed in this embodiment includes a placement table 2. The inner wall of the placement table 2 is provided with a plurality of limiting grooves 3. The moving direction and range of the irregular claw 44 and the fixed shell 54 are limited by the limiting grooves 3. The placement table 2 is provided with a positioning structure 4 inside and a shock-absorbing structure 5 on the outer wall of the placement table 2.

[0041] The positioning structure 4 includes a connecting plate 41. The outer wall of the connecting plate 41 is slidably connected to the inner wall of the placement platform 2. A first connecting rod 42 is rotatably connected to the inner wall of the connecting plate 41. An L-shaped push rod 43 is hinged to the outer wall of the end of the first connecting rod 42 away from the connecting plate 41. A fixed shaft 47 passes through the corner of the L-shaped push rod 43, thereby limiting the rotation range of the L-shaped push rod 43 through the fixed shaft 47. A shaped gripper 44 is rotatably connected to the outer wall of the L-shaped push rod 43. The inner wall of the shaped gripper 44 is provided with anti-slip texture 45. The gripping surface of the shaped gripper 44 is provided with anti-slip texture 45. The anti-slip texture 45 can increase the friction between the irregular-shaped gripper 44 and the material, and increase the gripping force and stability of the irregular-shaped gripper 44 on the material. The outer wall of the irregular-shaped gripper 44 is hinged with a second link 46. The rotation of the second link 46 stabilizes the movement of the irregular-shaped gripper 44 and can share the pressure on the L-shaped push rod 43, increasing the stability of the movement and gripping of the material by the irregular-shaped gripper 44. The outer walls of the L-shaped push rod 43 and the second link 46 are both hinged with fixed shafts 47. The L-shaped push rod 43 and the second link 46 are respectively restricted by the same fixed shafts 47.

[0042] like Figure 3-6 As shown, the shock absorption structure 5 includes a support block 51. The outer wall of the support block 51 is fixedly connected to the top outer wall of the connecting plate 41. Since the support block 51 is fixed to the outside of the connecting plate 41, the movement of the connecting plate 41 drives the support block 51 to move synchronously. Several inclined push blocks 52 are fixedly connected to the outer wall of the support block 51. An inclined top block 53 is slidably connected to the outer wall of the inclined push block 52. By the inclined surface of the inclined push block 52 and the inclined surface of the inclined top block 53 being in contact, the up and down movement of the inclined push block 52 can drive the inclined top block 53 to move synchronously. A pressure spring 55 is fixedly connected to the outer wall of the inclined top block 53. The elasticity of the pressure spring 55 can continuously provide sufficient thrust to the inclined top block 53, ensuring that the inclined surface of the inclined top block 53 and the inclined push block 52 always remain in contact, and ensuring that the movement of the inclined push block 52 can stably push the inclined top block 53 to move horizontally.

[0043] A fixed outer shell 54 is fixedly connected to the top outer wall of the inclined top block 53. A shock-absorbing plate 56 is slidably connected to the inner wall of the fixed outer shell 54. The movement of the inclined top block 53 pushes the fixed outer shells 54 on both sides to move synchronously, and drives the shock-absorbing plate 56 to fit against the surface of the material, ensuring that the shock-absorbing plate 56 fits tightly against the surface of the material and that the shock-absorbing component 57 set inside the fixed outer shell 54 can operate normally, absorbing the vibration of the material itself. The movement of the fixed outer shell 54 is synchronized with the movement of the irregular gripper 44, which also enables the irregular gripper 44 to clamp the material while performing secondary positioning of the material. The inner wall of the fixed outer shell 54 is provided with a shock-absorbing component 57.

[0044] like Figure 6-7 As shown, the shock absorption assembly 57 includes a positioning seat 571. A first support rod 572 is rotatably connected to the outer wall of the positioning seat 571. A positioning shaft 573 is hinged to the outer wall of the first support rod 572 away from the positioning seat 571. A second support rod 574 is hinged to the outer wall of the positioning shaft 573. The positioning shaft 573 passes through both the first support rod 572 and the second support rod 574, ensuring that the first support rod 572 and the second support rod 574 always maintain a connection. A connecting seat 575 is rotatably connected to the outer wall of the second support rod 574 away from the positioning shaft 573. The rotation and connection of the first support rod 572 and the second support rod 574 can generate sufficient support force for the shock absorption plate 56, preventing the shock absorption plate 56 from shaking. A connecting block 576 is hinged to the outer wall of the positioning shaft 573. A spring damper 577 is fixedly connected to the outer wall of the connecting block 576. The spring damper 577 relieves and absorbs the pressure on the first support rod 572 and the second support rod 574.

[0045] like Figure 1-4 As shown, a support base 1 is fixedly connected to the bottom outer wall of the tabletop 2, and an electric push rod 6 is fixedly connected to the bottom inner wall of the support base 1. The output end of the electric push rod 6 is fixedly connected to the outer wall of the connecting plate 41. Electric push rods 6 of the same model are provided on both the left and right sides of the support base 1, and the two electric push rods 6 operate synchronously.

[0046] like Figure 1-4 As shown, the outer wall of the irregular-shaped gripper 44 is slidably connected to the inner wall of the placement table 2. The irregular-shaped gripper 44 and the L-shaped push rod 43 are detachably connected and can be replaced with a flat gripper or a V-shaped gripper. The outer wall of the fixed shaft 47 is fixedly connected to the inner wall of the placement table 2.

[0047] like Figure 1-4 As shown, the outer wall of the L-shaped push rod 43 is slidably connected to the inner wall of the placement platform 2, and the outer wall of the second connecting rod 46 is slidably connected to the inner wall of the placement platform 2.

[0048] like Figure 1-6As shown, the outer wall of the support block 51 is slidably connected to the inner wall of the placement platform 2, and the outer wall of the inclined push block 52 is slidably connected to the inner wall of the placement platform 2.

[0049] like Figure 1-6 As shown, the outer wall of the inclined top block 53 is slidably connected to the inner wall of the placement platform 2, and the outer wall of the pressure spring 55 is fixedly connected to the inner wall of the placement platform 2.

[0050] like Figure 5-7 As shown, the outer wall of the fixed housing 54 is slidably connected to the outer wall of the placement platform 2, and the outer wall of the shock-absorbing plate 56 is fixedly connected to the outer wall of the connecting seat 575.

[0051] In this embodiment, a positioning process for welding ship components includes the following steps:

[0052] Step 1: Equipment debugging and adaptation: According to the specifications and shape of the ship parts to be welded, replace the irregular jaw 44 with a suitable flat jaw or V-shaped jaw, check the connection status of each component of the positioning structure 4 and the shock absorption structure 5 to ensure smooth equipment operation.

[0053] Step 2: Workpiece placement and positioning: Place the ship component to be welded on the damping plate 56 of the placement platform 2, and activate the electric push rod 6 inside the support base 1. The electric push rod 6 pushes the connecting plate 41 to slide and move on the inner wall of the placement platform 2.

[0054] Step 3: Adaptive clamping and fixing: During the movement of the connecting plate 41, the first connecting rod 42 is driven to transmit power, and the fixed shaft 47 is limited to drive the L-shaped push rod 43 to work in conjunction with the second connecting rod 46, which drives the irregular claw 44 to fit against the outer wall of the ship component. The anti-slip texture 45 achieves stable clamping and fixing of the workpiece, and completes the precise positioning of the workpiece.

[0055] Step 4: Welding vibration reduction and protection: During the welding operation, the vibration generated by the workpiece is transmitted to the damping plate 56, which drives the connecting seat 575, the second support rod 574 and the first support rod 572 to swing in conjunction, and achieves primary vibration reduction in conjunction with the spring damper 577 on the outside of the positioning shaft 573; at the same time, the support block 51 slides with the connecting plate 41, which drives the inclined push block 52 to squeeze the inclined top block 53 and the pressure spring 55, achieving secondary buffering and vibration reduction to offset the welding vibration;

[0056] Step 5: Unloading and Resetting: After the ship component welding is completed, control the electric push rod 6 to reset, drive the positioning structure 4 to spring back as a whole, and the irregular jaw 44 to release the workpiece, remove the welded ship component, and complete the single welding positioning operation.

[0057] The working principle of the above embodiment is as follows: After aligning and fitting the sides of the two materials to be welded, they are placed on the surface of the placement table 2. Then, the two electric push rods 6 are activated simultaneously, and the electric push rods 6 drive the connecting plate 41 to move synchronously along the inside of the placement table 2.

[0058] During the movement of the connecting plate 41, the first connecting rod 42 moves accordingly and pulls the L-shaped push rod 43, causing the L-shaped push rod 43 to rotate around the fixed axis 47. Through the rotation of the L-shaped push rod 43, the irregular gripper 44 is pushed to move synchronously towards the material. The two irregular grippers 44 on the same side move closer together at the same time, thereby fixing the material on the top of the placement table 2.

[0059] During the movement of the irregular-shaped gripper 44, the second connecting rod 46 rotates synchronously around another fixed axis 47. The function of the second connecting rod 46 is to share the pressure borne by the L-shaped push rod 43, preventing the L-shaped push rod 43 from deforming due to excessive force on one side; and to increase the stability of the irregular-shaped gripper 44 during movement, ensuring uniform contact between the irregular-shaped gripper 44 and the material surface. The gripping surface of the irregular-shaped gripper 44 is provided with anti-slip texture 45. The function of the anti-slip texture 45 is to increase the friction between the irregular-shaped gripper 44 and the material, preventing the material from slipping due to vibration or external force during welding, while allowing the clamping force to be appropriately reduced, reducing indentation damage to the material surface.

[0060] Two irregularly shaped grippers 44 on the other side of the table 2 clamp another material in the same way, thereby achieving synchronous positioning of the two materials in the horizontal direction. As the connecting plate 41 moves, the support block 51 moves synchronously. The support block 51 drives the inclined push block 52 to move in the same direction. The inclined surface of the inclined push block 52 fits with the inclined surface of the inclined top block 53, pushing the two inclined top blocks 53 to move synchronously towards the middle.

[0061] A pressure spring 55 is provided between the inclined top block 53 and the inner wall of the placement platform 2. The function of the pressure spring 55 is to continuously provide sufficient thrust to the inclined top block 53, ensuring that the inclined surface of the inclined top block 53 and the inclined push block 52 always remain in contact, avoiding loosening of the contact due to manufacturing tolerances or long-term wear, thereby ensuring the long-term stability of the shock-absorbing structure 5. During the movement of the inclined top block 53, the fixed outer shell 54 slides along the surface of the placement platform 2, pushing the shock-absorbing plate 56 to contact the surface of the material. The moving distance of the fixed outer shell 54 matches the moving distance of the irregular gripper 44. Therefore, while the irregular gripper 44 clamps the material, the shock-absorbing plate 56 also simultaneously contacts the surface of the material, realizing secondary positioning of the material.

[0062] When the damping plate 56 is attached to the material surface, the vibration generated during the welding process is transmitted to the damping plate 56. The damping plate 56 slides along the inside of the fixed housing 54, pushing the first support rod 572 and the second support rod 574 to rotate around the positioning shaft 573. The function of the first support rod 572 and the second support rod 574 is to convert the vibration energy received by the damping plate 56 into mechanical motion through rotation, and at the same time support and guide the movement of the damping plate 56 to prevent the damping plate 56 from shaking or shifting, and to prevent the weld seam position deviation due to the instability of the damping plate. During the rotation of the first support rod 572 and the second support rod 574, the positioning shaft 573 moves in the direction of the stretching spring damper 577. A spring damper 577 is provided between the two positioning shafts 573. Two connecting blocks 576 fix the two ends of the spring damper 577 respectively, and fix the spring damper 577 to the outside of the positioning shaft 573.

[0063] The vibration and pressure received by the damping plate 56 are transmitted to the positioning shaft 573 through the first support rod 572, and then to the spring damper 577 through the connecting block 576. The spring damper 577 converts the vibration energy into heat energy and releases it slowly through its internal elastic element and damping medium, thereby achieving vibration absorption and buffering. This achieves multi-level absorption and buffering of welding vibration, while ensuring the movement stability of the damping plate 56, avoiding welding deviation caused by vibration, and improving welding quality.

[0064] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described herein. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present invention, as well as all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present invention.

Step 2: Workpiece placement and positioning: Place the ship component to be welded on the damping plate (56) of the placement table (2), start the electric push rod (6) inside the support base (1), and the electric push rod (6) pushes the connecting plate (41) to slide displacement on the inner wall of the placement table (2); Step 3: Adaptive clamping and fixing: During the movement of the connecting plate (41), the first connecting rod (42) is driven to transmit power, and the fixed shaft (47) is limited to drive the L-shaped push rod (43) to work in conjunction with the second connecting rod (46), thereby driving the irregular gripper (44) to fit against the outer wall of the ship component. The anti-slip texture (45) is used to achieve stable clamping and fixing of the workpiece, and complete the precise positioning of the workpiece. Step 4: Welding vibration reduction and protection: During the welding operation, the vibration generated by the workpiece is transmitted to the damping plate (56), which drives the connecting seat (575), the second support rod (574) and the first support rod (572) to swing in linkage, and cooperates with the spring damper (577) on the outside of the positioning shaft (573) to achieve primary vibration reduction; at the same time, the support block (51) slides with the connecting plate (41), which drives the inclined push block (52) to squeeze the inclined top block (53) and the pressure spring (55) to achieve secondary buffering and vibration reduction, and offset the welding vibration; Step 5: Unloading and Resetting: After the ship parts are welded, control the electric push rod (6) to reset, drive the positioning structure (4) to spring back as a whole, and the irregular jaws (44) to release the workpiece, remove the welded ship parts, and complete the single welding positioning operation.
