[0002] The marine diesel engine frame is the support system of the diesel engine, bearing the weight and load of the engine, ensuring the stability and durability of the engine. Another function of the diesel engine frame guide is to guide the connecting piston rod slider.

[0015] Place the welding tooling on a stable workbench to ensure that the bottom plate is stable and immovable;

[0016] Check whether all components are firmly installed, especially the connection parts of the I-shaped frame, the mounting bracket and the drive source;

[0017] Prepare the cross beam and the guide plate to be welded to ensure that they meet the design requirements;

[0018] Cross beam installation:

[0019] Insert one end of the cross beam into the through hole at one end of the I-shaped frame and gently push it to the appropriate position, and then tighten several bolts at both ends of the I-shaped frame;

[0020] Repeat the above steps to insert the other end of the cross beam into the through hole at the other end of the I-shaped frame;

[0021] At this time, the cross beam should be placed parallel to the bottom plate;

[0022] Adjust the I-shaped frame:

[0023] Start the drive source to drive the first worm to rotate;

[0024] The worm 1 drives the worm gear 1 to rotate, which in turn drives the connecting shaft 1 and the I-shaped frame to rotate 90 degrees, changing the crossbeam from a horizontal position to a vertical position;

[0025] Ensure that the crossbeam is firmly fixed in the vertical position;

[0026] Install and fix the guide plate:

[0027] Place the guide plate on both sides of the mounting frame, close to the jaws;

[0028] Use a tool to rotate the worm 2, causing the worm gear 2 to rotate;

[0030] Ensure that the guide plate is firmly clamped on the mounting frame;

[0031] Adjust the position of the mounting frame:

[0032] If it is necessary to adjust the relative position between the guide plate and the crossbeam, start the drive source to drive the worm 3 to rotate;

[0033] The worm 3 drives the worm gear 3 to rotate, which in turn drives the connecting shaft 2 and the mounting frame to rotate 90 degrees;

[0034] Note that since the helix directions of the worm 1 and the worm 3 are opposite, their rotation directions are also opposite, and careful control is required to avoid conflicts;

[0035] Adjust the position of the mounting frame so that the guide plate can be smoothly inserted between the two crossbeams;

[0036] Welding operation:

[0037] After confirming that the crossbeam and the guide plate are both in the correct positions and firmly fixed, start the welding operation;

[0042] Release the jaws and remove the welded frame crossbeam component;

[0043] Clean the welding slag and dirt on the welding fixture to prepare for the next use.

[0045] Improve welding efficiency and precision: The welding tooling for the marine diesel engine frame crossbeam component realizes precise rotation control of the I-shaped frame and the mounting frame through a precise worm and worm gear transmission mechanism. This design not only simplifies the adjustment steps during the welding process but also greatly improves the welding precision and efficiency, reducing errors caused by improper manual operation.

[0047] Improve flexibility and adaptability: Both the I-shaped frame and the mounting frame can rotate independently, and the rotation angle can be precisely controlled by the driving source. This design enables the tooling to adapt to different combinations of crossbeams and guide plates with different sizes and shapes, improving the flexibility and adaptability of the welding tooling.
