Technical Field
[0001] The utility model relates to the technical field of marine diesel engines, in particular to an adjustment tool for a WINGD series main engine rocker arm support. Background Art
[0002] At present, based on the increasing demand for WINGD series main engine production capacity, the assembly cycle of WINGD series main engines has been greatly shortened, and the requirements for the efficiency of related process execution have become higher. The WINGD rocker arm is the lubricating oil circuit of the main engine piston crosshead. It is installed on the crosshead and connected to the frame. There are relevant requirements for the sensitivity and clearance. Secondly, the adjustment operation of the main engine rocker arm takes a long time, and during the adjustment operation, other operations in the machine cannot be carried out at the same time, resulting in a longer assembly time. At the same time, the current rocker arm adjustment operation is mostly based on experience, which makes it impossible to quantify and fine-tune, which is not friendly to novices. Therefore, further improvement is needed. Utility Model Content

[0031] One end of the jacking bolt 1 is threadedly connected to the bolt hole, and the end face of one end of the jacking bolt 1 is connected to the surface of the corresponding position of the rocker arm support 5. The fixing nut 4 is installed on the surface of one end of the adjustment tooling 2 and aligned with the through hole. One end of the fixing bolt 3 passes through the through hole and is threadedly connected to the inside of the fixing nut 4. A limiting screw hole that can be threadedly connected to the fixing bolt 3 is opened on the surface of the rocker arm support 5, and the end head of one end of the fixing bolt 3 is threadedly connected in the limiting screw hole.
[0032] A yielding ring groove 6 is provided in the middle of the fixing nut 4, and a damping sleeve 7 and a buffer spring 8 are provided on one end of the yielding ring groove 6. The two ends of the buffer spring 8 are respectively fixedly connected to the end face of one end of the damping sleeve 7 and the inner wall of one end of the yielding ring groove 6. The damping sleeve 7 and the buffer spring 8 are combined into a damping buffer structure, which then buffers and protects the vibration of the connection between the fixing nut 4 and the fixing bolt 3. The other end of the damping sleeve 7 is a conical structure, and the inner wall of the damping sleeve 7 is provided with friction lines and is closely connected to the inner wall of one end of the yielding ring groove 6, thereby achieving a buffer extension effect of friction energy dissipation;
[0033] A U-shaped rod 9 and a spring sheet 10 are arranged in the other end of the yield ring groove 6. Both ends of the U-shaped rod 9 are fixedly connected to the inner wall of the other end of the yield ring groove 6. A yield hole is opened inside one end of the spring sheet 10, and one end of the spring sheet 10 is movably sleeved on the outer side of the middle part of the U-shaped rod 9 through the yield hole. A torsion spring is sleeved in the yield hole, and the two ends of the torsion spring are respectively fixedly connected to the surface of the middle part of the U-shaped rod 9 and the inner wall of the yield hole. By utilizing the combined buffer structure of the U-shaped rod 9, the spring sheet 10 and the torsion spring, the target structure can be subsequently buffered for structural deformation. One end of the spring sheet 10 uses the middle part of the U-shaped rod 9 as the rotation base axis, and can rotate to press the damping sleeve 7. Therefore, after the spring sheet 10 synchronously receives the vibration pressure of the rocker arm support 5, pressure is applied to the damping sleeve 7 and the buffer spring 8 while the spring sheet 10 performs structural deformation buffering, so that the damping sleeve 7 and the buffer spring 8 cooperate to perform damping buffering;

The other end of the spring leaf 10 is a rounded structure, and the other end of the spring leaf 10 uses the middle part of the U-shaped rod 9 as the rotation base axis, and can rotate to press the rocker arm support 5, thereby allowing the spring leaf 10 to synchronously receive the vibration pressure of the rocker arm support 5, so that the spring leaf 10 can perform structural deformation buffering.
[0035] Working principle: When adjusting the rocker arm, the operator pre-installs the adjustment tool 2, the fixing bolt 3 and the fixing nut 4 on the rocker arm support 5, and then installs the jacking bolt 1 into the bolt hole. During the adjustment operation, the operator installs the tool in the required direction according to the actual situation, and adjusts the screw-in amount of the jacking bolt 1, so as to achieve the purpose of adjusting the rocker arm support;
[0036] Later, during the synchronous use of the adjustment tool 2 and the rocker arm support 5, one end of the spring sheet 10 uses the middle part of the U-shaped rod 9 as the rotation base axis, and can rotate to press the damping sleeve 7. Therefore, after the spring sheet 10 synchronously receives the vibration pressure of the rocker arm support 5, while the spring sheet 10 performs structural deformation buffering, pressure is applied to the damping sleeve 7 and the buffer spring 8, so that the damping sleeve 7 and the buffer spring 8 cooperate to perform damping buffering, thereby comprehensively improving the stability of the rocker arm support 5 and the adjustment tool 2 during use. The other end of the spring sheet 10 uses the middle part of the U-shaped rod 9 as the rotation base axis, and can rotate to press the rocker arm support 5, thereby making the spring sheet 10 synchronously receive the vibration pressure of the rocker arm support 5 so that the spring sheet 10 can perform structural deformation buffering.
