Description

Technical Field

[0001] This utility model relates to the field of connecting rod shaping technology, specifically a tool for shaping connecting rods of marine diesel generator auxiliary machines. Background Technology

[0002] The connecting rod of a marine diesel generator auxiliary machine is a key component. It is shaped like a slender rod with different mechanical parts connected to its two ends. One end is connected to the piston, and the other end is connected to the crankshaft. During the operation of the generator, it undertakes the important task of converting the reciprocating linear motion of the piston into the rotational motion of the crankshaft. Through periodic oscillation, it continuously transmits power. Just like a joint in the human body, it plays an indispensable role in maintaining the stable operation and power transmission of the marine diesel generator auxiliary machine.

[0003] In existing technology, the method for fixing the position of the auxiliary connecting rod of a marine diesel generator is to use a bench vise with custom-made pads. The custom-made pads, which are adapted to the shape of the connecting rod, are placed in the jaws of the bench vise, and then the auxiliary connecting rod is placed between the pads. By rotating the handle of the bench vise, the jaws are gradually tightened. Relying on the tight fit between the pads and the connecting rod and the clamping force of the bench vise, the connecting rod is firmly fixed in the required position. This method is simple to operate, does not require complicated equipment, and the bench vise and pads are inexpensive. It is suitable for a variety of common connecting rod shaping operations.

[0004] While using a bench vise with custom-made pads to fix the auxiliary connecting rod of a marine diesel generator is simple to operate and low in cost, it also has many drawbacks. First, it lacks flexibility. Custom-made pads are only suitable for connecting rods of specific shapes and sizes. When encountering connecting rods of different specifications, pads need to be made again, which is difficult to meet diverse needs and cannot efficiently fix the auxiliary connecting rod. To address the above problems, a tool for shaping the auxiliary connecting rod of a marine diesel generator is proposed. Utility Model Content

The first spring 7 raises the limit rod 8 to fix the auxiliary connecting rod 30. When it is necessary to clean the auxiliary connecting rod 30, the hydraulic cylinder 19... The drive causes the housing 18 to move downwards. When the limiting block 27 contacts the auxiliary connecting rod 30, the second spring 26 causes the limiting block 27 to move upwards under pressure, causing the cleaning agent in the brush ring 24 to flow out. Then, the fourth servo motor 21 drives the second gear 22 to rotate, causing the third gear 23 to drive the brush ring 24 to wipe the auxiliary connecting rod 30. Finally, the fan 33 dries the surface of the auxiliary connecting rod 30. The third servo motor 15 drives the lead screw 16 to rotate, and the rotation of the lead screw 16 causes the nut pair 17 to move, facilitating the brush ring 24 to wipe the auxiliary connecting rod 30. Finally, the hydraulic cylinder 19 on the right drives the pressure plate 29 to shape the auxiliary connecting rod 30, thus completing the cleaning and shaping of the auxiliary connecting rod 30.
