Description

Technical Field

[0001] The utility model relates to the technical field of profile welding tooling, in particular to a device for preventing deformation of a weld-through area of ​​a T-profile panel. Background Art

[0002] During the shipbuilding process, T-profiles are assembled by welding panels and webs to strengthen the structural strength of the hull. The T-profile panel is welded by fixing the panel and webs on a welding frame and welding the whole at a certain inclination angle. During the welding process, the high temperature caused by the welding arc will cause the panel penetration area to be in a local high temperature state. Uneven heating will cause the panel to deform to a certain extent. Therefore, the welding quality of the panel penetration area directly determines the strength of the entire T-profile, which in turn affects the hull structural performance of the entire ship. The existing welding process for T-profile panels has low flatness after welding. If the deformation is large and the weld cracks, it will need to be repaired or even scrapped. Utility Model Content

[0003] In view of the above problems, the utility model proposes a device for preventing deformation of the weld penetration area of ​​the T-profile panel, which is used for the position in the weld penetration area of ​​the T-profile panel that is prone to bending deformation, to prevent bending deformation caused by the high temperature generated during welding.

[0004] To achieve the above purpose, the following technical scheme is adopted: a device for preventing deformation of the weld penetration area of ​​a T-profile panel, comprising a pressure plate, a pressure head, a crossbeam, an adjusting screw and a clamping arm group, the crossbeam is installed on the adjusting screw, and the two are threadedly connected, a rotary actuator is installed at the upper end of the adjusting screw, and a pressure head is installed at the lower end, the lower ends of the two clamping arms of the clamping arm group are clamping ends, and the clamping ends are provided with hook-shaped grooves for clamping the workpiece panel, the two clamping arms of the clamping arm group are respectively arranged at the two side ends of the crossbeam, and maintain a clamping angle with the crossbeam while being connected to the crossbeam through a connecting plate, the connecting plate is connected to the clamping arm and the crossbeam by a rotating shaft to ensure that when the crossbeam moves up, the linkage connecting plate clamps the clamping ends of the two clamping arms to the workpiece panel, the pressure plate is located on the workpiece panel, and the pressure head is located above the pressure plate and acts on the pressure plate.

[0005] Furthermore, the middle section of the clamping arm is connected to the connecting plate via a rotating shaft, and the upper section of the clamping arm corresponds to the side end surface of the beam, ensuring that when the clamping ends of the two clamping arms are opened to the maximum distance, the upper section is stuck on the side end surface of the beam, thereby limiting the opening distance of the clamping ends of the clamping arms.

[0006] Furthermore, the maximum opening distance of the clamping ends of the two clamping arms does not exceed 1.5 times the width of the workpiece panel.

[0007] Further, the pressing head acts on a pressing plate position corresponding to a center line in the length direction of the workpiece panel.

[0008] Furthermore, at least one side edge of the pressing plate is provided with a group of clamping grooves adapted to the side end surface of the workpiece panel, and the clamping grooves of the pressing plate clamp the side end surface of the workpiece panel.

[0009] Beneficial effects of the utility model: the utility model adjusts the clamping arm to fix the workpiece panel by adjusting the screw rod to move the crossbeam upward, and at the same time, the pressure head applies pressure to the pressure plate, so that the workpiece panel is restricted by the pressure plate to prevent bending deformation caused by high temperature during welding, and the pressure plate bears the pressure to avoid defects on the surface of the workpiece panel after concentrated force. The utility model has a simple structure and is easy to operate. It can effectively limit the bending deformation caused by welding. The panel does not need to be corrected after welding, which ensures the welding quality and welding effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Example 1

[0015] The following is further described with reference to the accompanying drawings: Figure 1-3 The schematic diagram of this example is a device for preventing deformation of a weld penetration area of ​​a T-shaped panel, as shown in the figure, comprising a pressing plate 1, a pressing head 2, a crossbeam 3, an adjusting screw 4 and a clamping arm assembly. The crossbeam 3 is assembled on the adjusting screw 4. Through the thread engagement of the two, the crossbeam 3 can move on the adjusting screw 4. A rotary actuator 5 is installed on the upper end of the adjusting screw 4, and a pressing head 2 is installed on the lower end.

[0016] The lower ends of the two clamping arms 6 of the clamping arm group are clamping ends 600, and the clamping ends 600 are provided with hook-shaped grooves for clamping the workpiece panel. The two clamping arms 6 of the clamping arm group are respectively arranged at the two side ends of the beam 3 and maintain a clamping angle with the beam 3. At the same time, the two clamping arms 6 are respectively connected to the beam 3 through the connecting plate 7. Specifically, the connecting plate 7 is connected to the clamping arm 6 and the beam 3 by a rotating shaft 8, so that the clamping arm 6, the connecting plate 7 and the beam 3 are linked to each other to ensure that when the beam 3 moves up, the linkage The movable connecting plate 7 clamps the clamping ends 600 of the two clamping arms 6 to the workpiece panel 900, connects the middle section 601 of the clamping arm 6 to the connecting plate 7 through the rotating shaft 8, and the upper section 602 of the clamping arm 6 corresponds to the side end surface of the beam 3, ensuring that when the clamping ends 600 of the two clamping arms 6 are opened to the maximum distance, the upper section 602 is stuck on the side end surface of the beam 3, and the maximum opening distance of the clamping ends 600 of the two clamping arms 6 is limited to no more than 1.5 times the width of the workpiece panel 900. For example, the width of the panel of the ship under construction is generally between 100mm-250mm and the thickness is 15-30mm. In this embodiment, taking a panel with a width of 200mm as an example, the maximum opening distance of the clamping ends 600 of the two clamping arms 6 is limited to no more than 300mm.

[0017] When in use, the pressing head 2 cooperates with the pressing plate 1, the pressing plate 1 is located on the workpiece panel 900, and the pressing head 2 is located above the pressing plate 1 and acts on the pressing plate 1. At least one side edge of the pressing plate 1 is provided with a group of slots adapted to the side end face of the workpiece panel 900, and the slots of the pressing plate 1 clamp the side end face of the workpiece panel 900 to prevent it from falling off when pressed.

[0018] Before welding, the panel 900 and the web 800 are fixed on a welding frame, and the device described in this example is evenly installed at intervals along the length direction of the panel 900.

[0019] The pressing plate 1 is installed on the panel 900, and the slot on the side edge of the pressing plate 1 is clamped on the side end face of the panel 900. The pressing head 2 is placed on the pressing plate 1, corresponding to the center line position of the workpiece panel 900, and then the two clamping arms 6 are placed on the two side ends of the workpiece panel 900 to ensure that the two side ends of the panel 900 are located on the hook-shaped groove surface of the clamping end 600 of the two clamping arms 6. Finally, the rotating actuator 5 at the upper end of the adjusting screw 4 is rotated to gradually raise the crossbeam 3 and gradually press the pressing head 2 downward, so that the device described in this example is clamped on the workpiece panel 900. At this time, the pressing plate 2 always applies pressure to the workpiece panel 900, so as to prevent the panel from bending and deformation caused by high temperature during welding.
