Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, and particularly relates to a welding turnover auxiliary device for bridge rib plates. Background Art

[0002] In the field of bridge construction, rib plate welding is a key process for connecting the rib plates in the bridge structure with the bridge girder. For some bridge rib plates such as triangular rib plates, it is necessary to weld the two right-angled sides to the L-shaped base body. During the automatic welding process, the triangular rib plate needs to be turned over to achieve the welding of both sides; however, due to inconvenient operation or lack of an effective auxiliary device, the rib plate is prone to displacement, inclination or even dropping during the turnover process, and the safety performance of the rib plate and the operator cannot be guaranteed, which brings great difficulties to the welding operation. Content of the Utility Model

[0003] To solve the above problems, the utility model provides a welding turnover auxiliary device for bridge rib plates, which includes a base, on which an installation seat is slidably connected. A turnover disk is arranged on the installation seat. A deep arc groove is formed at the top of the installation seat, and the turnover disk is placed on the deep arc groove. An L-shaped placement plate for placing the rib plate is fixed on the side wall of the turnover disk. A stepping motor is arranged on one side of the turnover disk, and the output end of the stepping motor is connected with a driving rod, and the other end of the driving rod is fixed to the side wall of the turnover disk; on the side of the turnover disk where the placement plate is arranged, there is a welding part. Above the turnover disk, there is a U-shaped stabilizing frame, and the bottom end of the stabilizing frame extends to the front side of the placement plate. On the top of the base, a linear driver is fixed on the side of the installation seat, and the telescopic end of the linear driver is fixed to the side wall of the installation seat through a connecting seat, and an action structure for driving the stabilizing frame to clamp the rib plate on the placement plate is provided.

[0004] Furthermore, the action structure includes a vertical rod rotatably connected to the base. A lower tooth groove is formed on the side wall of the installation seat close to the vertical rod. A lower straight gear meshing with the lower tooth groove is fixed on the outer side surface of the vertical rod. An inverted L-shaped connecting seat is fixed on the base, and a deep groove is formed on the outer wall of the connecting seat. One end of the stabilizing frame is inserted into the deep groove. An upper tooth groove is formed on the side wall of the stabilizing frame close to the vertical rod. An upper straight gear meshing with the upper tooth groove is fixed on the outer side surface of the vertical rod, and the outer diameter of the upper straight gear is larger than that of the lower straight gear.

[0005] Furthermore, at one end of the stabilizing frame close to the placement plate, a connected inner circular groove and outer circular groove are formed. The inner diameter of the inner circular groove is larger than that of the outer circular groove, and the outer circular groove communicates with the outside. An inner disk rotates in the inner circular groove, and an outer rod fixed to the side wall of the inner disk passes through the outer circular groove, and the other end of the outer rod is fixed with a contact disk.

[0006] Furthermore, rubber anti-slip particles are fixed on the side wall of the contact disk.

[0007] Further, the welded part includes a welding torch. A sliding seat is fixed to the bottom of the welding torch. A guide rail is arranged below the sliding seat. A servo motor is installed on the guide rail. The output end of the servo motor is connected to a bidirectional ball screw that is connected to the sliding seat.

[0008] The beneficial effects of the present utility model are as follows:

[0017] The following further describes the present utility model in conjunction with the accompanying drawings of the specification:

[0018] A welding turnover assisting device for bridge rib plates, as Figure 1 and Figure 3 shown, includes a base 1, on which a mounting seat 2 is slidably connected. A turnover disk 3 is arranged on the mounting seat 2. A deep arc groove is formed at the top of the mounting seat 2, and the turnover disk 3 is placed on the deep arc groove. An L-shaped placement plate 4 for placing rib plates is fixed on the side wall of the turnover disk 3. A stepping motor 5 is arranged on one side of the turnover disk 3, the output end of the stepping motor 5 is connected with a driving rod 6, and the other end of the driving rod 6 is fixed to the side wall of the turnover disk 3; on the side of the turnover disk 3 where the placement plate 4 is arranged, there is a welded part. Above the turnover disk 3, a U-shaped stabilizing frame 9 is arranged. The bottom end of the stabilizing frame 9 extends to the front side of the placement plate 4. On the top of the base 1, a linear driver 10 is fixed on the side of the mounting seat 2, and the telescopic end of the linear driver 10 is fixed to the side wall of the mounting seat 2 through a connecting seat 11.

[0019] As Figure 1 shown, in this embodiment, an action structure for driving the stabilizing frame 9 to clamp the rib plates on the placement plate 4 is provided. The action structure includes a vertical rod 81 rotatably connected to the base 1. A lower tooth groove 82 is formed on the side wall of the mounting seat 2 close to the vertical rod 81. A lower straight gear 83 meshing with the lower tooth groove 82 is fixed on the outer side surface of the vertical rod 81. An inverted L-shaped connecting seat 84 is fixed on the base 1. A deep groove 85 is formed on the outer wall of the connecting seat 84. One end of the stabilizing frame 9 is inserted into the deep groove 85. An upper tooth groove 86 is formed on the side wall of the stabilizing frame 9 close to the vertical rod 81. An upper straight gear 87 meshing with the upper tooth groove 86 is fixed on the outer side surface of the vertical rod 81, and the outer diameter of the upper straight gear 87 is larger than that of the lower straight gear 83.

[0020] As Figure 1 and Figure 2 shown, in this embodiment, at one end of the stabilizing frame 9 close to the placement plate 4, a connected inner circular groove and outer circular groove are formed. The inner diameter of the inner circular groove is larger than that of the outer circular groove, and the outer circular groove communicates with the outside. An inner disk 12 is rotatably arranged in the inner circular groove. An outer rod 13 passing through the outer circular groove is fixed on the side wall of the inner disk 12, and the other end of the outer rod 13 is fixed with a contact disk 14; rubber anti-slip grains 15 are fixed on the side wall of the contact disk 14.

[0021] As Figure 1 shown, in this embodiment, the welded part includes a welding torch 71. A sliding seat 72 is fixed to the bottom of the welding torch 71. A guide rail 73 is arranged below the sliding seat 72. A servo motor 74 is installed on the guide rail 73. The output end of the servo motor 74 is connected to a bidirectional ball screw that is connected to the sliding seat 72.

[0022] The working principle of the present utility model is as follows:

[0023] Place the rib plate to be welded on the placement plate 4. Start the servo motor 74 and the welding torch 71. The servo motor 74 drives the bidirectional ball screw to rotate, thereby driving the sliding seat 72 to move along the axial direction of the bidirectional ball screw. While the welding torch 71 moves together with the sliding seat 72, the bottom end of the rib plate is welded to achieve single-sided welding of the rib plate.

[0024] After single-sided welding is completed, start the linear driver 10 to retract and drive the mounting seat 2 to move, thereby driving the rib plate away from the welding torch 71 to prevent damage to the welding torch 71 during the flipping process. During the movement of the mounting seat 2, the lower straight gear 83 is driven to rotate through the lower tooth groove 82, thereby driving the vertical rod 81 to rotate. When the vertical rod 81 rotates, the upper straight gear 87 is driven to rotate. The upper straight gear 87 cooperates with the upper tooth groove 86 to drive the stabilizing frame 9 to move towards the rib plate. Since the outer diameter of the upper straight gear 87 is larger than that of the lower straight gear 83, that is, the moving stroke of the stabilizing frame 9 is larger than that of the mounting seat 2, the contact disc 14 at one end of the stabilizing frame 9 will eventually clamp the rib plate to prevent the rib plate from shifting or even falling during the flipping process.

[0025] Start the stepping motor 5 to rotate 90 degrees, thereby driving the flipping disc 3, the placement plate 4 and the rib plate to rotate 90 degrees together. During the rotation process, the rubber anti-slip particles 15 of the contact disc 14 contact the rib plate. Through the settings of the inner disc 12 and the outer disc, the contact disc 14 rotates together with the rib plate to avoid abrasion of the contact disc 14 and the rib plate. After the rotation is completed, start the linear driver 10 to drive the mounting seat 2 to return to its original position, and the welding torch 71 can then weld the other end of the rib plate.

[0026] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
