[0002] As a key component of marine diesel engines, the connecting rod requires pre-inspection of its large end dimensions before final assembly. This is to prevent dimensional discrepancies from being discovered during assembly, which could lead to failure. Therefore, the large end of the connecting rod needs to be pre-tightened and its bore diameter measured before assembly, and compared with the crankshaft journal dimensions to ensure installation requirements are met. Secondly, the small end of the connecting rod requires cold fitting of the bushing and measurement of its dimensions to ensure a proper fit between the small end and the piston.

[0003] Previously, when technicians pre-assembled the large and small ends of connecting rods, the connecting rods were placed on plastic foot pedals. The technicians then had to lift and flip the connecting rods. For connecting rods on small diesel engines, which are smaller and lighter, pre-assembly was relatively easy. However, as the company's business has continued to expand, there has been a demand for medium and large-sized diesel engines. The connecting rods for medium and large-sized diesel engines are large and heavy, making manual pre-assembly difficult and time-consuming, and posing a safety risk.

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0034] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0035] Please see Figures 1 to 8A connecting rod assembly platform for medium and large marine diesel engines includes: a base plate 1, side supports 2, a motor mount 3, a synchronous motor 4, a first gear 5, a mounting bracket 6, a connecting shaft 7, a second gear 8, a drive mechanism 9, a cylinder 10, a movable seat 12, and a sleeve 13. The side supports 2 and the motor mount 3 are symmetrically fixedly connected to the top of the base plate 1. The synchronous motor 4 is installed inside the motor mount 3, and the output end of the synchronous motor 4 is fixedly connected to the second gear 8. The connecting shaft 7 is rotatably connected inside the side supports 2. A rotating beam 14 is provided between the side supports 2. Opposite ends of the connecting shaft 7 are fixedly connected to the rotating beam 14. The first gear 5 is fixedly connected to the outside of the connecting shaft 7, and the first gear 5 meshes with the corresponding second gear 8. The mounting bracket 6 is fixedly connected to one side of the rotating beam 14. A movable seat 12 is provided on the top of the base plate 1, and a cylinder 10 is mounted on the top of the movable seat 12. The output end of the cylinder 10 is fixedly connected to a base 17, and the top of the base 17 is fixedly connected to a sleeve 13. Inside the sleeve 13, a fixing ring 19, a first partition 23, a second partition 24, and a side plate 25 are fixedly connected in sequence. Inside the sleeve 13, a circular plate 18 is slidably connected. Inside the fixing ring 19, a rotating plate 20 is rotatably connected. The surface of the circular plate 18 has waist-shaped sliding holes 31 equidistantly opened, and the surface of the rotating plate 20 has curved sliding holes 28 equidistantly opened. Inside the sleeve 13, movable rods 26 are equidistantly arranged. One end of the movable rod 26 passes through the corresponding waist-shaped sliding hole 31 and the curved sliding hole 28 in sequence, and the movable rod 26 is slidably connected to the corresponding waist-shaped sliding hole 31 and the curved sliding hole 28. One end of each movable rod 26 is fixedly connected to a stop block 30. The movable rod 26, the curved sliding hole 28, and the waist-shaped sliding hole 31 are all arranged in a circular array with the center of the rotating plate 20 as the center point. A drive mechanism 9 is installed inside the sleeve 13.

[0036] It should be noted that the connecting rod can be fixed on the rotating beam 14 by the mounting bracket 6. First, one end of the connecting rod on the rotating beam 14 is pre-assembled. After assembly, the second gear 8 drives the first gear 5 to rotate through the synchronous motor 4, thereby driving the rotating beam 14 to rotate through the connecting shaft 7, and further causing the connecting rod to flip so that the other end can be reassembled.

[0037] Please see Figure 1 A movable component 11 is mounted on the top of the substrate 1, and the moving end of the movable component 11 is fixedly connected to the movable base 12.

[0038] It should be noted that the position of the sleeve 13 can be adjusted by moving component 11;

[0039] Please see Figure 2 and Figure 3The mounting bracket 6 includes an acrylic plate 61, connecting columns 62, and positioning strips 63. An acrylic plate 61 is fixedly connected to one side of the rotating beam 14. Connecting columns 62 are fixedly connected to the four corners of one side of the acrylic plate 61. Positioning strips 63 are symmetrically arranged on one side of the acrylic plate 61. One end of the connecting column 62 is fixedly connected to the corresponding positioning strip 63. Both ends of the positioning strip 63 are provided with third threaded holes 65. Second threaded holes 64 are symmetrically arranged on both sides of the surface of the acrylic plate 61.

[0040] It should be noted that the positioning strip 63 of the mounting bracket 6 is fixed to the connecting column 62 by bolts passing through the third threaded hole 65. During assembly, the positioning strip 63 can be removed in advance so that the middle part of the connecting rod is embedded in the mounting bracket 6. After the positioning strip 63 is installed, the acrylic plate 61 can prevent the rod body from being damaged when the connecting rod is squeezed and contacted.

[0041] Please see Figure 1 and Figure 2 The rotating beam 14 has first threaded holes 16 at equal intervals on both sides perpendicular to the base plate 1.

[0042] It should be noted that the acrylic plate 61 is fixed by bolts passing through the second threaded hole 64 and threadedly connected to the corresponding first threaded hole 16 on the rotating beam 14. The rotating beam 14 is provided with multiple first threaded holes 16 to facilitate the installation of multiple mounting brackets 6.

[0043] Please see Figure 4 , Figure 6 and Figure 7 Inside the fixed ring 19, guide posts 29 are equidistantly slidably inserted, and the guide posts 29 are distributed in a ring array with the center of the fixed ring 19 as the center point. Inside the sleeve 13, a sliding ring 21 is slidably connected. The two ends of the guide posts 29 are fixedly connected to the circular plate 18 and the sliding ring 21 respectively. A push rod motor 22 is symmetrically installed between the first partition 23 and the second partition 24. The output end of the push rod motor 22 is fixedly connected to the sliding ring 21.

[0044] It should be noted that: the push rod motor 22 drives the sliding ring 21 to move, which in turn drives the guide post 29 to move the circular plate 18, thereby adjusting the length of the movable rod 26 on one side of the circular plate 18. This makes it easier to adjust the insertion length of the movable rod 26 according to the size of the connecting rod, making the connecting rod more stable when feeding.

[0045] Please see Figure 4 and Figure 5 The outer wall of the movable rod 26 is fixedly connected to retaining rings 27 on both sides of the rotating plate 20;

[0046] It should be noted that the retaining ring 27 makes the movable rod 26 slide more smoothly;

[0047] Please see Figures 4 to 8The drive mechanism 9 includes a drive gear 94, a rotating cylinder 95, an adjusting shaft 96, a driven gear 97, a slide rod 98, a rotating shaft 99, and a sliding cylinder 911. The rotating cylinder 95 is rotatably connected between the sliding ring 21 and the second partition 24. The driven gear 97 is fixedly connected to the outside of the rotating cylinder 95. The rotating shaft 99 is rotatably connected at equal intervals inside the first partition 23, and the rotating shaft 99 is arranged in a ring array around the rotating cylinder 95. The drive gear 94 is fixedly connected to the outside of one end of the rotating shaft 99. The drive gear 94 is meshed with the driven gear 97. The sliding cylinder 911 is rotatably connected to one end of the rotating shaft 99 through a universal joint. The slide rod 98 is slidably connected inside the sliding cylinder 911. One end of the slide rod 98 is rotatably connected to the corresponding movable rod 26 through a universal joint. The adjusting shaft 96 is fixedly connected to one side of the rotating plate 20. One end of the adjusting shaft 96 passes through the rotating cylinder 95 and is rotatably connected to the side plate 25.

[0048] It should be noted that during the rotation of the rotating plate 20, the curved sliding hole 28 slides on the outside of the corresponding movable rod 26, thereby guiding the movable rod 26 to slide and disperse along the waist-shaped sliding hole 31, allowing the movable rod 26 to separate and support one end of the connecting rod. As the movable rod 26 disperses, it also causes the sliding cylinder 911 and the sliding rod 98 to gradually tilt. As the distance between the end of the movable rod 26 and the corresponding rotating shaft 99 changes, the sliding rod 98 will slide inside the sliding cylinder 911. The rotating cylinder 95 drives multiple driving gears 94 to rotate through the driven gear 97, thereby causing the rotating shaft 99 to drive the corresponding movable rod 26 to rotate through the universal joint connected sliding rod 98 and sliding cylinder 911, so that the stop block 30 at its end blocks one side of the connecting rod, preventing the connecting rod from slipping off the movable rod 26.

[0049] Please see Figures 4 to 8 The second partition 24 is symmetrically fixedly connected to the first partition 23 and the side plate 25 with fixing plates 93. The second partition 24 is installed with drive motors 91 between the first partition 23 and the side plate 25. The fixing plates 93 on both sides of the second partition 24 are rotatably connected with worm gears 92. The output end of the drive motor 91 is fixedly connected to the corresponding worm gear 92. The outer sides of the rotating drum 95 and the adjusting shaft 96 are fixedly connected with worm wheels 910. The worm wheels 910 are meshed with the corresponding worm gears 92.

[0050] It should be noted that when the drive motor 91 between the side plate 25 and the second partition 24 starts, it will drive the worm wheel 910 on the adjusting shaft 96 to rotate through the corresponding worm 92, which in turn drives the rotating plate 20 to rotate. The drive motor 91 between the first partition 23 and the second partition 24 can drive the worm wheel 910 on the rotating drum 95 to rotate through the corresponding worm 92, which in turn drives the rotating drum 95 to rotate through the driven gear 97 to drive multiple driving gears 94 to rotate.

[0051] Please see Figure 1 and Figure 2An arc-shaped plate 15 is fitted on the outer side of the first gear 5, and the arc-shaped plate 15 is fixedly connected to the corresponding side support 2.

[0052] It should be noted that the arc-shaped plate 15 can protect the outer side of the first gear 5.

[0053] Please see Figures 1 to 9 A method for using a connecting rod assembly table for medium and large marine diesel engines, the specific steps of which are as follows:

[0054] 1) Adjust the position and height of the sleeve 13 by moving component 11 and cylinder 10, insert the movable rod 26 into one end of the connecting rod to be assembled, and use the drive mechanism 9 to separate the movable rod 26 and support it on one end of the connecting rod. Then, use the drive mechanism 9 to rotate the movable rod 26 so that the stop block 30 at its end blocks one side of the connecting rod to prevent the connecting rod from slipping off the movable rod 26.

[0055] 2) The connecting rod on the movable rod 26 is conveyed to the mounting bracket 6 by the moving component 11, so that the middle part of the connecting rod is embedded in the mounting bracket 6 and fixed to the rotating beam 14 by the mounting bracket 6.

[0056] 3) After the connecting rod is fixed in the mounting bracket 6, the movable rod 26 on the moving seat 12 is brought closer to each other and separated from the connecting rod by the drive mechanism 9 and the moving component 11;

[0057] 4) Pre-assemble one end of the connecting rod on the rotating beam 14. After assembly, rotate the rotating beam 14 by the synchronous motor 4 to perform the transfer operation on the other end of the connecting rod.

[0058] 5) The movable rod 26 is inserted into one end of the assembled connecting rod by the drive mechanism 9 and the moving component 11, the connecting rod is removed, and the next connecting rod is loaded onto the mounting bracket 6 and fixed, thereby assembling the next connecting rod.

[0059] The working principle of the medium and large marine diesel engine connecting rod assembly table and its usage method provided by the present invention is as follows: First, the connecting rod to be assembled is lifted up. The sleeve 13 on the moving seat 12 is adjusted by the moving component 11 on the base plate 1. The height of the sleeve 13 is adjusted by the cylinder 10 so that one end of the movable rod 26 can be inserted into the interior of one end of the lifted connecting rod. The spacing between the movable rods 26 is adjusted by the drive mechanism 9. When the drive motor 91 between the side plate 25 and the second partition plate 24 is started, it will drive the worm wheel 910 on the adjusting shaft 96 to rotate through the corresponding worm 92. This will further drive the adjusting shaft 96 to rotate the rotating plate 20. During the rotation of the rotating plate 20, the movable rods 26 slide on the outside of the corresponding movable rods 26 through the curved sliding hole 28, thereby guiding the movable rods 26 to slide and disperse along the waist-shaped sliding hole 31. This allows the movable rods 26 to separate and support one end of the connecting rod. As the movable rods 26 disperse, they will also... As the movable cylinder 911 and the sliding rod 98 gradually tilt, the distance between the end of the movable rod 26 and the corresponding rotating shaft 99 changes, causing the sliding rod 98 to slide inside the cylinder 911. Activating the drive motor 91 between the first partition 23 and the second partition 24 allows the corresponding worm gear 92 to drive the worm wheel 910 on the rotating cylinder 95 to rotate. This further causes the rotating cylinder 95 to drive multiple drive gears 94 to rotate via the driven gear 97, thereby causing the rotating shaft 99 to rotate via the universal joint connecting the sliding rod 98 and the cylinder 911, thus rotating the corresponding movable rod 26. This causes the stop block 30 at the end of the rod to block one side of the connecting rod, preventing the connecting rod from slipping off the movable rod 26. The push rod motor 22 drives the sliding ring 21 to move, further causing the guide post 29 to move the circular plate 18, thereby adjusting the length of the movable rod 26 on one side of the circular plate 18. This facilitates adjusting the insertion length of the movable rod 26 according to the size of the connecting rod, making the connecting rod more stable during material feeding.

[0060] The connecting rod fixed on the movable rod 26 is moved towards the mounting bracket 6 by the movable component 11. The positioning strip 63 of the mounting bracket 6 is fixed to the connecting column 62 by bolts passing through the third threaded hole 65. The acrylic plate 61 is fixed by bolts passing through the second threaded hole 64 and threadedly connected to the corresponding first threaded hole 16 on the rotating beam 14. During assembly, the positioning strip 63 can be removed in advance so that the middle part of the connecting rod is embedded in the mounting bracket 6. After the positioning strip 63 is installed, the connecting rod is fixed to the rotating beam 14. The rotating beam 14 has multiple first threaded holes 16 to facilitate the installation of multiple mounting brackets 6 so that multiple connecting rods can be installed and assembled simultaneously. After the connecting rod is fixed in the mounting bracket 6, the movable rod 26 on the moving seat 12 is brought closer to each other and separated from the connecting rod by the drive mechanism 9 and the moving component 11. Pre-assembly is performed on one end of the connecting rod on the rotating beam 14. After assembly, the second gear 8 drives the first gear 5 to rotate by the synchronous motor 4, thereby driving the rotating beam 14 to rotate through the connecting shaft 7, further causing the connecting rod to flip so that the other end can be reassembled. After assembly, the movable rod 26 is inserted into one end of the assembled connecting rod by the drive mechanism 9 and the moving component 11, and the connecting rod is removed. The next connecting rod is then loaded onto the mounting bracket 6 and fixed, thereby assembling the next connecting rod.

[0061] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention.
