Description

Technical Field

[0001] This utility model relates to the field of ship welding technology, and in particular to a tooling for controlling welding deformation of ship hull plates. Background Technology

[0002] In shipbuilding, the welding quality of hull plates is crucial, and welding deformation has always been a pressing problem to be solved in the industry. During welding, due to the heat of the electric arc, the temperature of the welding area of ​​the hull plate rises rapidly, causing uneven thermal expansion within the plate. After welding, this area cools and contracts rapidly. This uneven thermal expansion and contraction leads to stress within the plate, resulting in welding deformation. Common forms of welding deformation include longitudinal shrinkage deformation, transverse shrinkage deformation, angular deformation, wave deformation, and torsional deformation. These deformations not only affect the smoothness of the hull's appearance but also severely weaken the strength and stability of the hull structure, reducing the ship's load-bearing capacity and safety.

[0003] Currently, rigid fixing is used to control welding deformation of ship hull plates. This involves using tooling to firmly clamp the plates, utilizing the rigidity of the tooling to resist welding deformation stress. However, existing tooling has significant limitations. Its structural design is only suitable for plates of specific shapes, making it difficult to meet the diverse needs of actual production. Furthermore, the parts of the clamps that contact the plates in traditional tooling are often of a fixed shape, failing to conform well to the surface contours of the plates. This results in poor fixing effectiveness and an inability to effectively control welding deformation of the plates.

[0004] Therefore, there is an urgent need for a tooling for controlling welding deformation of ship hull plates to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a tooling for controlling the welding deformation of ship hull plates. This solves the problem that existing tooling has obvious limitations, its structural design is only suitable for plates of specific shapes, and it is difficult to meet the diverse needs in actual production. At the same time, the part of the clamp that contacts the plate in traditional tooling is mostly of a fixed shape, which leads to poor fixing effect of the tooling and cannot effectively control the welding deformation of the plate. Therefore, this utility model proposes a tooling for controlling the welding deformation of ship hull plates.

[0006] The purpose of this utility model is achieved as follows:

[0007] A tooling for controlling welding deformation of ship hull plates includes a base plate. A first adjusting frame and a second adjusting frame are symmetrically mounted on the top of the base plate. A first clamping mechanism and a second clamping mechanism are respectively provided on the inner side of the first adjusting frame and the second adjusting frame. Both the first clamping mechanism and the second clamping mechanism include a first mounting plate and a second mounting plate arranged symmetrically. A plurality of evenly distributed hydraulic telescopic rods are mounted on the bottom of the first mounting plate and the top of the second mounting plate. A mounting frame is fixedly mounted on the moving end of the hydraulic telescopic rod. A multi-faceted clamp is rotatably mounted on the inner side of the mounting frame. A fixing mechanism that cooperates with the multi-faceted clamp is provided on the outer side of the mounting frame.

[0008] Furthermore, the mounting frame includes a frame body fixedly installed on the moving end of the hydraulic telescopic rod, and the fixing mechanism includes a positioning block fixedly installed on the side wall of the frame body, with a threaded screw threadedly installed through the positioning block.

[0009] Furthermore, the multi-faceted chuck includes a mounting base rotatably mounted inside the frame via a connecting shaft, and the connecting shaft has multiple threaded holes that cooperate with the screw.

[0010] Furthermore, the outer wall of the mounting base is surrounded by a flat pad, an arc-shaped concave pad, a V-shaped concave pad, and an arc-shaped protruding pad.

[0011] Furthermore, the first adjusting frame includes a vertical rod fixedly installed on the top of the base plate, a threaded rod fixedly connected to the top of the vertical rod, a first limiting nut and a second limiting nut threadedly connected to the outer side of the threaded rod, and a connecting plate movably installed on the outer side of the threaded rod between the first limiting nut and the second limiting nut, the connecting plate being used to connect the first mounting plate.

[0012] Furthermore, the top of the base plate is equipped with multiple lifting mechanisms distributed on the outside of the first adjustment frame and the second adjustment frame.

[0013] Furthermore, the lifting mechanism includes a sleeve fixedly installed on the top of the base plate, a sliding rod slidably installed on the inner side of the sleeve and extending through its top, a limiting piece fixedly connected to the bottom of the sliding rod, a spring provided between the bottom of the limiting piece and the sleeve, and a support block located on the outer side of the sleeve fixedly connected to the top of the sliding rod.

[0014] Compared with the prior art, this utility model provides a tooling for controlling welding deformation of ship hull plates, which has the following beneficial effects:

[0015] (1) When this utility model is used, it can clamp and fix two plates that need to be welded through the first clamping mechanism and the second clamping mechanism. During clamping and fixing, multiple hydraulic telescopic rods installed on the first mounting plate and the second mounting plate can clamp and fix the plates from the top and bottom of the plates at the same time. At the same time, the extension length of the multiple hydraulic telescopic rods can be adjusted according to the contour shape of the plates, which is convenient for use with plates of different contour shapes, improves the versatility of the tooling, and meets the diverse needs in actual production.

[0016] (2) By setting up an installation frame, a multi-faceted clamp and a fixing mechanism, the multi-faceted clamp installed inside the installation frame can be rotated and adjusted according to the contour of the plate surface during use. After adjustment, the multi-faceted clamp can be fixed by the fixing mechanism, so that the face of the multi-faceted clamp that matches the contour of the plate is aligned with the plate, and the multi-faceted clamp fits the surface contour of the plate better. This allows the plate to be firmly clamped in conjunction with the hydraulic telescopic rod and the installation frame, better controlling the deformation of the plate during welding and avoiding poor welding deformation control.

It should be understood that the specific embodiments described below are not intended to limit the specific implementation of the technical solution of this utility model, but are merely possible implementations of the technical solution of this utility model. It should be noted that the descriptions of the positional relationships of the components herein, such as component A being located above component B, are based on the relative positions of the components in the illustrations and are not intended to limit the actual positional relationships of the components. Example 1

[0025] See Figure 1-5 , Figure 1 A structural schematic diagram of a tooling for controlling welding deformation of ship hull plates in Embodiment 1 has been drawn. As shown in the figure, this embodiment 1 relates to a welding deformation control fixture for ship hull plates, including a base plate 1. A first adjusting frame 2 and a second adjusting frame 3 are symmetrically installed on the top of the base plate 1. A first clamping mechanism 4 and a second clamping mechanism 5 are respectively provided on the inner side of the first adjusting frame 2 and the second adjusting frame 3. The first clamping mechanism 4 and the second clamping mechanism 5 each include a first mounting plate 401 and a second mounting plate 402 symmetrically arranged. Multiple evenly distributed hydraulic telescopic rods 403 are installed on the bottom of the first mounting plate 401 and the top of the second mounting plate 402. In use, the first clamping mechanism 4 and the second clamping mechanism 5 can clamp and fix the two plates to be welded. During clamping and fixing, the multiple hydraulic telescopic rods 403 installed on the first mounting plate 401 and the second mounting plate 402 can clamp and fix the plates from the top and bottom at the same time. At the same time, the extension length of the multiple hydraulic telescopic rods 403 can be adjusted according to the contour shape of the plates, which is convenient for use with plates of different contour shapes, improves the versatility of the fixture, and meets the diverse needs in actual production.

[0026] The movable end of the hydraulic telescopic rod 403 is fixedly equipped with a mounting frame 7. A multi-faceted clamp 8 is rotatably mounted on the inner side of the mounting frame 7, and a fixing mechanism that cooperates with the multi-faceted clamp 8 is provided on the outer side of the mounting frame 7. By setting up the mounting frame 7, the multi-faceted clamp 8, and the fixing mechanism, the multi-faceted clamp 8 rotatably mounted on the inner side of the mounting frame 7 can be rotated and adjusted according to the contour of the plate surface during use. After adjustment, the multi-faceted clamp 8 can be fixed by the fixing mechanism, so that the face of the multi-faceted clamp 8 that cooperates with the contour of the plate is aligned with the plate, and the multi-faceted clamp 8 better fits the surface contour of the plate. This allows the hydraulic telescopic rod 403 and the mounting frame 7 to firmly clamp the plate, better control the deformation of the plate during welding, and avoid poor welding deformation control.

[0027] The mounting frame 7 includes a frame body 701 fixedly mounted on the moving end of the hydraulic telescopic rod 403. The fixing mechanism includes a positioning block 702 fixedly mounted on the side wall of the frame body 701. A screw 703 threadedly connected to the positioning block 702 is threaded through it. The multi-faceted chuck 8 includes a mounting seat 801 rotatably mounted on the inner side of the frame body 701 via a connecting shaft 807. The connecting shaft 807 has multiple screw holes 806 that cooperate with the screw 703. It should be noted that during use, the mounting seat 801 can be rotated via the connecting shaft 807 to adjust the contact surface between the mounting seat 801 and the plate. After adjustment, the screw 703 on the positioning block 702 is screwed into the screw holes 806 to fix the connecting shaft 807, thereby fixing the mounting seat 801.

[0028] The outer wall of the mounting base 801 is surrounded by a flat pad 802, an arc-shaped concave pad 803, a V-shaped concave pad 804, and an arc-shaped protruding pad 805. It should be noted that by using multiple pads of different shapes, the surface contour of the material can be flexibly selected during use, thereby better conforming to the surface of the material and enabling it to work more securely with the hydraulic telescopic rod 403 and the mounting bracket 7 to clamp and fix the material.

[0029] The first adjusting frame 2 includes a vertical rod 201 fixedly installed on the top of the base plate 1. A threaded rod 202 is fixedly connected to the top of the vertical rod 201. A first limiting nut 203 and a second limiting nut 205 are threadedly connected to the outer side of the threaded rod 202. A connecting plate 204 is movably installed on the outer side of the threaded rod 202 between the first limiting nut 203 and the second limiting nut 205. The connecting plate 204 is used to connect the first mounting plate 401. It should be noted that, during use, the height of the connecting plate 204 can be adjusted by adjusting the position of the first limiting nut 203 and the second limiting nut 205 on the threaded rod 202. Thus, the distance between the first mounting plate 401 and the second mounting plate 402 can be adjusted by moving the 204, which is convenient for use with plates of different sizes.

[0030] The top of the base plate 1 is equipped with multiple lifting mechanisms 6 distributed on the outer sides of the first adjusting frame 2 and the second adjusting frame 3. Each lifting mechanism 6 includes a sleeve 601 fixedly installed on the top of the base plate 1. A sliding rod 602 is slidably installed on the inner side of the sleeve 601, passing through its top. A limiting piece 603 is fixedly connected to the bottom of the sliding rod 602. A spring 604 is provided between the bottom of the limiting piece 603 and the sleeve 601. A support block 605 located outside the sleeve 601 is fixedly connected to the top of the sliding rod 602. It should be noted that during use, the sleeve 601, sliding rod 602, and support block 605 can support the plate. The spring 604 provides the support block 605 at the top of the sliding rod 602 with an elastic floating function. When the surface of the plate has unevenness or a curved contour, the support block 605 can automatically adjust its height through the compression or extension of the spring, closely fitting the surface of the plate. The limiting piece 603 prevents the sliding rod 602 from detaching from the sleeve 601.

[0031] Working principle:

[0032] This utility model provides a tooling for controlling welding deformation of ship hull plates. In use, two plates are clamped inside a first clamping mechanism 4 and a second clamping mechanism 5, respectively, so that the weld seam is positioned between the first clamping mechanism 4 and the second clamping mechanism 5. During clamping and fixing, multiple hydraulic telescopic rods 403 mounted on the first mounting plate 401 and the second mounting plate 402 can simultaneously clamp and fix the plates from the top and bottom. Simultaneously, the extension length of the multiple hydraulic telescopic rods 403 can be adjusted according to the contour shape of the plates, automatically adapting to plates with different contour shapes. During clamping, the multi-faceted clamp 8, rotatably mounted inside the mounting frame 7, can be rotated and adjusted according to the contour of the plate surface. After adjustment, the multi-faceted clamp 8 is fixed by a fixing mechanism, thereby aligning the face of the multi-faceted clamp 8 that matches the plate contour with the plate, allowing the multi-faceted clamp 8 to better conform to the surface contour of the plate, thus enabling the hydraulic telescopic rods 403 and the mounting frame 7 to firmly clamp the plates.

[0033] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
