Description

Technical Field

[0001] This utility model belongs to the field of mechanical tooling technology, specifically relating to a fixing tool for a ship turbocharger. Background Technology

[0002] Marine turbochargers are core auxiliary devices for marine engines. Their function is to increase the engine's intake pressure and volume, allowing for more complete combustion of fuel, thereby enhancing power and reducing fuel consumption.

[0003] It mainly consists of a turbine and a compressor. The turbine is driven to rotate by the high-temperature exhaust gas from the engine, which in turn drives the coaxial compressor. The compressor draws in air, compresses it, and then sends the high-pressure air into the engine cylinder. Its components are mostly made of high-temperature resistant and wear-resistant materials, making it suitable for the high-load and long-term operation conditions of marine engines.

[0004] It can improve engine efficiency without changing the size of the engine, and also reduce exhaust emissions and fuel costs, making it a key part of modern marine power systems.

[0005] In existing technologies, such as Figure 1 The marine turbocharger shown is relatively large and requires multiple steps to process. During this process, a clamping fixture is needed for holding the components. However, existing fixtures, such as three-jaw chucks, require the operator to manually rotate the drive mechanism several times to perform the clamping and releasing actions. To ensure clamping stability, the drive mechanism needs to be twisted forcefully after clamping to further increase the clamping force. This clamping process is cumbersome, resulting in low parts processing efficiency and making it difficult to meet the high-efficiency processing requirements of marine turbocharger components.

Detailed Implementation

[0037] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0038] like Figure 2-9 As shown, this utility model provides a marine turbocharger fixing fixture, including...

[0039] Base 1, with an assembly plate 11 detachably mounted on its top;

[0040] A circular fixed platform 2 is fixedly installed at the top center of the assembly plate 11; a through groove 21 is provided in the middle of the circular fixed platform 2, and a number of weight-reducing grooves 22 are provided around the periphery of the circular fixed platform 2, and a connection port 23 is provided between the weight-reducing grooves 22 and the through groove 21.

[0041] A circular groove 31 is provided at the center of the top of the fixed plate 3.

[0042] The through slot 21, weight reduction slot 22, connection port 23, and circular slot 31 can reduce the overall weight of the fixed tooling during handling while meeting strength requirements.

[0043] Fixed plate 3 is fixedly installed on the top of circular fixed platform 2, and a positioning circular groove 4 is provided on the top of fixed plate 3;

[0044] The counterweight assembly 5 is installed on the top left side of the assembly plate 11; specifically, the counterweight assembly 5 includes two counterweight blocks 51, which are arranged front to back on the top left side of the assembly plate 11.

[0045] In initial use, the marine turbocharger is placed inside the positioning groove 4 on the top of the fixed plate 3. The size and shape of the positioning groove 4 match the bottom flange of the marine turbocharger. After placement, the bottom of the marine turbocharger, excluding the flange, will abut against the top of the fixed plate 3, thus ensuring a stable installation of the marine turbocharger. During processing, it will not shift, and its secure placement allows for easy removal of the turbocharger after processing. This eliminates the need for repeated clamping and releasing operations, effectively improving worker efficiency. Because the marine turbocharger has an asymmetrical structure, such as... Figure 1 and Figure 2 As shown, after placement, the two counterweights 51 can balance the weight distribution on the assembly plate 11, making the installation more stable. Both counterweights 51 are fixedly connected to the assembly plate 11 by bolts. During batch processing, there is no need to frequently replace the counterweights. After replacing the assembly plate 11 to try installing different sizes of marine turbochargers, counterweights 51 of different weights can be replaced, making it highly adaptable.

[0046] Orientation mechanism 6 is installed on the top right side of assembly plate 11; specifically, orientation mechanism 6 includes two orientation components, which are arranged front to back and assembled on the top right side of assembly plate 11.

[0047] The orientation component includes an assembly block 61, the bottom of which is fixedly connected to the top of the assembly plate 11. Two through holes 62 are opened on the upper left side of the assembly block 61, and an orientation rod 63 is inserted into one of the through holes 62.

[0048] During use, the two directional rods 63 are used to determine the installation direction of the ship's supercharger to avoid incorrect orientation. The right side plane of the ship's supercharger needs to correspond to the position of the two directional rods 63. After installation, push the two directional rods 63 to abut against the right side plane of the ship's supercharger. The two through holes 62 have different heights, so the corresponding through holes 62 can be inserted according to different usage requirements.

[0049] A plurality of limiting grooves 64 are evenly provided on the rear side of the directional rod 63. A sliding groove 65 is provided on the inner wall of the rear side of the through hole 62. A limiting block 66 is slidably assembled inside the sliding groove 65. A spring 67 is fixedly installed on the rear side of the limiting block 66. One end of the spring 67 is fixedly connected to the inner wall of the sliding groove 65. A pull rod 68 is fixedly installed on the rear side of the limiting block 66. The rear end of the pull rod 68 extends out of the assembly block 61 and is fixedly installed with a pulling block 69. An inclined surface 661 is provided on the right side of the front side of the limiting block 66.

[0050] When the guide rod 63 needs to be inserted into the through hole 62 of the assembly block 61 to abut against the right end plane of the ship's supercharger, the guide rod 63 will abut against the inclined surface 661 on the right side of the front of the limiting block 66 during insertion. As the guide rod 63 continues to be inserted, the inclined surface 661 will have a guiding effect, pushing the limiting block 66 to slide backward along the slide groove 65, while compressing the spring 67. Until the guide rod 63 moves to abut against the right end plane of the ship's supercharger, at this time the limiting groove 64 on the guide rod 63 corresponding to the limiting block 66 is exactly aligned with the slide groove 65, the compressed spring 67 restores its deformation, pushes the limiting block 66 forward, and makes it lock into the limiting groove 64, thus completing the locking and fixing of the guide rod 63 and preventing the ship's supercharger from rotating.

[0051] When it is necessary to pull out the guide rod 63 to unlock it, the pull block 69 must be pulled manually. This causes the limit block 66 to slide backward via the pull rod 68, compressing the spring 67. This causes the limit block 66 to disengage from the limit groove 64 of the guide rod 63 and fully retract into the slide groove 65. At this time, the locked state of the guide rod 63 is released, and it can be easily pulled out from the through hole 62. This operation method is simple and quick, and can achieve rapid positioning.

[0052] The base 1 is surrounded by several positioning discs 7, and a connecting plate 71 is fixedly installed around the periphery of the several positioning discs 7. A wrapping ring 72 is fixedly installed on the top of the base 1. Several positioning lasing plates 73 are evenly provided at the bottom of the assembly plate 11. Several assembly holes are opened on the top of the positioning discs 7 to match the positions of the several positioning lasing plates 73. Insertion sleeves 74 are fixedly installed inside the several assembly holes. The several positioning lasing plates 73 are respectively inserted into the several insertion sleeves 74.

[0053] The specific usage of this structure revolves around the positioning and installation of the assembly plate 11 and the base 1. Stable assembly is achieved through the precise matching of prefabricated components. The specific process is as follows:

[0054] First, confirm the pre-installed state of the base 1. Without disassembling the base 1, several positioning discs 7 are already arranged around its top. A connecting plate 71 is fixedly installed around the periphery of these positioning discs 7, and a wrapping ring 72 is also fixedly installed on the top of the base 1, forming a stable assembly base. At the same time, several assembly holes are opened on the top of the positioning discs 7, and a plug-in sleeve 74 is fixedly installed inside each assembly hole.

[0055] Next, the assembly plate 11 is installed. First, several positioning Latin bars 73 evenly distributed at the bottom of the assembly plate 11 are aligned with the positions of the insertion sleeves 74 on the positioning plate 7. After alignment, the assembly plate 11 is placed downwards, so that each positioning Latin bar 73 is inserted into the corresponding insertion sleeve 74.

[0056] By engaging the positioning lasing plate 73 with the insertion sleeve 74, the assembly plate 11 can be positioned and installed on the base 1. Furthermore, the overall structure of the positioning plate 7, the connecting plate 71, and the wrapping ring 72 further ensures the stability of the assembly plate 11 after installation. When replacing it later, the assembly plate 11 can be directly removed and replaced, and the operation method is the same as the above operation process.

[0057] The top of the base 1 is surrounded by several pull rings 8; the pull rings 8 are used to connect with external transport devices to facilitate position transfer.

[0058] The device is used as follows:

[0059] In use, the base 1 serves as a fixed foundation, with several positioning discs 7 arranged around its top forming a whole through connecting plates 71, and an outer wrapping ring 72. Insertion sleeves 74 are pre-installed in the mounting holes of the positioning discs 7. First, align the positioning lasing plates 73 at the bottom of the mounting disc 11 with the insertion sleeves 74 on the positioning disc 7 one by one. Then, place the mounting disc 11 downwards so that the positioning lasing plates 73 insert into the insertion sleeves 74, completing the positioning and installation of the mounting disc 11 and the base 1. If it is necessary to replace the mounting disc 11 to adapt to different sizes of marine turbochargers, simply remove the old mounting disc and install the new mounting disc according to the above steps.

[0060] Next, the ship's supercharger is fixed: First, the supercharger is placed in the fixed plate 3 on the circular fixed platform 2 at the top of the assembly plate 11, so that the bottom flange of the supercharger is embedded in the positioning groove 4 of the fixed plate 3, and the non-flange part of the bottom of the supercharger abuts against the top of the fixed plate 3, thus initially achieving positioning; then, the directional rods 63 of the two directional components in the directional mechanism 6 on the right side of the assembly plate 11 are pushed so that they are inserted along the through hole 62 of the assembly block 61. During the insertion process, the directional rod 63 abuts against the inclined surface 661 of the limiting block 66, pushing the limiting block 66 to compress the spring 67 and slide into the slide groove 65; when the directional rod 63 is fully abutted against the right side plane of the supercharger, the spring 67 returns to its original position and pushes the limiting block 66 into the limiting groove 64 of the directional rod 63, thus locking the directional rod 63 and preventing the supercharger from rotating.

[0061] After processing, manually pull the pull block 69 of the orientation mechanism 6, and the pull rod 68 will drive the limit block 66 to compress the spring 67 to disengage from the limit groove 64. Pull out the orientation rod 63 to release the lock, and the ship's supercharger can be removed directly. If the entire device needs to be moved, it can be connected to an external transport device through the pull ring 8 on the top of the base 1 to realize the position transfer.

[0062] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
