[0020] Figure 1 This is a schematic structural diagram of an automatic welding workbench for marine fasteners, such as... Figure 1 As shown, and with reference Figure 2 and Figure 3 This utility model provides an automatic welding workbench for marine fasteners, comprising a mounting frame 100, a welding platform 200, a fastening assembly 300, and a welding assembly 400. The welding platform 200 is horizontally positioned and rotatably mounted above the mounting frame 100. A limiting boss 210 is provided on the welding platform 200, located at the axis of the welding platform 200.

[0021] The fastening assembly 300 includes a fastening support arm 310, a fastening adjusting screw 320, a fastening adjusting block 330, and a fastening head 340. One end of the fastening support arm 310 is fixedly connected to the mounting bracket 100, and the other end extends above the welding platform 200. The fastening adjusting block 330 has a threaded hole and is fixedly disposed at the other end of the fastening support arm 310, located above the limiting boss 210. The fastening adjusting screw 320 is threadedly inserted into the threaded hole, and the fastening head 340 is rotatably mounted to the lower end of the fastening adjusting screw 320. The welding assembly 400 is fixed to the mounting bracket 100.

[0022] Specifically, the limiting boss 210 is used to place the bowl-shaped base to be welded. Inverting the bowl-shaped base onto the limiting boss 210 helps to limit and fix the base, preventing it from shifting and ensuring stability during welding. Furthermore, the fastening adjusting screw 320 can be rotated to adjust its height, thereby moving the fastening head 340 up and down. That is, when the bowl-shaped base needs to be fixed, rotating the adjusting screw causes the fastening head 340 to press down on the base. Therefore, the fastening assembly 300 further fixes and limits the bowl-shaped base.

[0023] Furthermore, the rotating configuration of the welding platform 200 enables the welding assembly 400 to perform rotational welding on the bowl-shaped base while the position is fixed, thereby improving welding efficiency and welding quality.

[0024] Furthermore, the fastening support arm 310 has a "C"-shaped rod structure, with one end fixed to the fastener and the other end positioned above the limiting boss 210. This ensures that the fastening adjustment block 330 is positioned above the limiting boss 210, thereby further ensuring that the fastening head 340 is pressed down on the bowl-shaped base to prevent the fastening head 340 from being pressed off-center and causing deformation of the bowl-shaped base.

[0025] During operation, the bowl-shaped base to be welded is first inverted onto the limiting boss 210. Then, the fastening adjusting screw 320 is rotated to move it downwards. As the fastening adjusting screw 320 moves downwards, the fastening head 340 comes into low contact with the bowl-shaped base, thereby fixing the bowl-shaped base in place. Next, the welding platform 200 is driven to rotate, and finally, the welding assembly 400 is started to weld the bowl-shaped base.

[0026] In this embodiment, in order to accommodate different models of bowl-shaped bases, the limiting boss 210 is detachably provided, so that limiting bosses 210 of different sizes can be replaced.

[0027] In some embodiments of this utility model, such as Figure 1 and Figure 2As shown, the welding assembly 400 includes a welding arm 410, a primary adjusting arm 420, a secondary adjusting arm 430, and a welding torch. One end of the welding arm 410 is fixedly connected to the mounting bracket 100, and the other end is located above the welding platform 200. The primary adjusting arm 420 is rotatably connected to the other end of the welding arm 410, and one end of the secondary adjusting arm 430 is rotatably connected to the other end of the primary adjusting arm 420, with the rotation axis of the secondary adjusting arm 430 perpendicular to the rotation axis of the primary adjusting arm 420. The welding torch is detachably mounted on the secondary adjusting arm 430.

[0028] Specifically, the pivot of the primary adjusting arm 420 extends horizontally, allowing it to rotate up and down; the pivot of the secondary adjusting arm 430 extends vertically, allowing it to rotate left and right. Since the welding torch is mounted on the secondary adjusting arm 430, the two-stage adjustment system consisting of the primary and secondary adjusting arms 420 allows for multi-directional adjustment of the welding torch, thereby improving its welding flexibility.

[0029] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, a first adjusting bolt 421 for adjusting the rotational damping of the first adjusting arm 420 is provided at the pivot of the welding arm 410 and the first adjusting arm 420. A second adjusting bolt 431 for adjusting the rotational damping of the second adjusting arm 430 is provided at the pivot of the first adjusting arm 420 and the second adjusting arm 430.

[0030] Specifically, the first adjusting bolt 421 and the second adjusting bolt 431 change the stability of the first-stage adjusting arm 420 and the second-stage adjusting arm 430 by adjusting the damping of the rotating shaft.

[0031] In this embodiment, the welding arm 410 has a "C"-shaped rod structure, and both the other end of the welding arm 410 and the other end of the first-stage adjusting arm 420 are provided with notches. The first-stage adjusting arm 420 is installed in the notch of the welding arm 410, and the first adjusting bolt 421 passes through the notch of the welding arm 410 and the first-stage adjusting arm 420. The first adjusting bolt 421 is the pivot of the first-stage adjusting arm 420, and can control the opening of the notch of the welding arm 410 to change the rotational damping of the first-stage adjusting arm 420. The second-stage adjusting arm 430 is rotatably installed in the notch of the first-stage adjusting arm 420, and the pivot of the second-stage adjusting arm 430 is rotatably inserted into the notch of the first-stage adjusting arm 420. The second adjusting bolt 431 is rotatably disposed on the first-stage adjusting arm 420, and one end is in low contact with the pivot of the second-stage adjusting arm 430, so as to control the rotational damping of the second-stage adjusting arm 430 by adjusting the low contact force.

[0032] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the secondary adjusting arm 430 includes a mounting ring, in which the welding torch is mounted. The mounting ring has an opening for adjusting the diameter. A third adjusting bolt 432 is provided at the opening of the mounting ring for adjusting the size of the opening.

[0033] Specifically, the larger the opening of the mounting ring, the larger the diameter of the mounting ring becomes, thus facilitating the installation of the welding gun.

[0034] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, a limiting nut 350 is installed on the fastening adjusting screw 320, and the limiting nut 350 is located above the fastening adjusting block 330. Specifically, the limiting nut 350 is positioned above the fastening adjusting block 330 so that when the limiting nut 350 is in low contact with the fastening adjusting block 330, the fastening adjusting screw 320 is restricted from moving downwards by the limiting nut 350, thereby preventing excessive downward displacement of the fastening adjusting screw 320 from causing compression deformation of the cup-shaped base.

[0035] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, a drive motor 110 is mounted on the mounting bracket 100. The drive motor 110 is connected to the welding platform 200 and is used to drive the welding platform 200 to rotate. Specifically, the drive motor 110 is a variable frequency motor. The variable frequency motor adjusts the rotation speed of the welding platform 200 in conjunction with the current adjustment of the welding gun to improve welding quality and welding speed. After all adjustments are made, automatic welding can be achieved through the automatic welding fixture.

[0036] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, a plurality of support rods 120 extend from the mounting frame 100. The plurality of support rods 120 are evenly distributed circumferentially along the axis of the welding platform 200. A roller 121 is rotatably provided above each support rod 120. The welding platform 200 is placed on the plurality of rollers 121.

[0037] Specifically, the lower surface of the welding platform 200 is provided with an annular track groove, and the roller 121 is located in the annular track groove so that the roller 121 is offset during the rotation of the welding platform 200, thereby increasing the stability of the welding platform 200.

[0038] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
