Description

Technical Field

[0001] This utility model relates to the technical field of internal combustion locomotive maintenance tools, and in particular to a diesel engine coupling installation tool. Background Technology

[0002] During the disassembly and overhaul of diesel locomotives, disassembling and overhauling the coupling is an essential step. However, numerous difficulties arise when subsequently installing the disassembled coupling assembly with the connecting plate and its bearing housing, severely hindering overhaul efficiency. Specific problems are as follows:

[0003] The coupling assembly is designed to be thicker in the middle and thinner at the edges. A bearing is installed at its center, requiring precise alignment with the bearing housing on the connecting plate. The assembly length is 200mm. Simultaneously, the edges of the assembly must be embedded into the connecting plate to ensure a tight fit. A ring of mounting holes is designed around the edges for securing the assembly to the connecting plate with bolts. During assembly, two problems arise: First, due to the high-speed rotation of the coupling, the bearing assembly is extremely precise to prevent centrifugal force, and the central bearing is relatively thick and deep. Therefore, any tilting during assembly can cause jamming, making assembly impossible. Second, the central bearing obstructs the bolts at the edges, creating excessive gaps between them and the connecting plate, hindering installation and severely delaying maintenance.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The purpose of this utility model is to provide a diesel engine coupling installation tool to solve the problems existing in the prior art. It has a simple structure, is easy to use, effectively ensures the installation effect, and effectively improves work efficiency.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] This utility model provides a diesel engine coupling installation tool 100, such as... Figures 1-2 As shown, the coupling includes a guide sleeve and a pusher. The guide sleeve includes a positioning shaft 1 and a guide shaft 2 integrally connected in sequence. The positioning shaft 1 is used to insert into the positioning hole 71 in the middle of the connecting plate 7 and is connected to the positioning hole 71 with a clearance fit. The guide shaft 2 is used to extend into the center hole 61 of the assembly 6 and is connected to the center hole 61 with a clearance fit to guide the assembly 6 to the connecting plate 7 during assembly. One end of the pusher is used to be detachably fixed to the connecting plate 7, and the other end is used to drive the assembly 6 to move towards the connecting plate 7. The clearance fit between the positioning shaft 1 of the guide sleeve and the positioning hole 71 of the connecting plate 7 can accurately determine the starting position of the installation and ensure the accuracy of the coupling installation. The clearance fit between the guide shaft 2 and the center hole 61 of the assembly 6 guides the assembly 6 to move along the accurate path when moving towards the connecting plate 7, avoiding deviation and jamming during the assembly process, and greatly improving the assembly accuracy and efficiency.

[0023] In a preferred embodiment, the propulsion component includes a collar 3, multiple pressure beams 4, and multiple bolts 5. The collar 3 is fitted onto the outside of the guide shaft 2. One end of the pressure beam 4 is fixedly connected to the collar 3, and the other end is provided with a through hole. The bolts 5 are threaded through the through hole, the mounting hole 62 of the assembly 6, and the screw hole 72 of the connecting plate 7. Rotating the bolts 5 enables the pressure beams 4 to push the assembly 6 towards the connecting plate 7 and complete the assembly. Utilizing the threaded transmission of the bolts 5, the pressure beams 4 can stably and controllably push the assembly 6, allowing operators to precisely control the movement of the assembly 6 by rotating the bolts 5, thus achieving a smooth and accurate assembly process. The collar 3, fitted onto the outside of the guide shaft 2, provides a stable support structure for the pressure beams 4, ensuring the effective transmission of force during the propulsion process and the stability of the entire propulsion action.

[0024] In a preferred embodiment, the contact surface between the pressure beam 4 and the assembly 6 is matched with the shape of the assembly 6. The matching shape of the contact surface between the pressure beam 4 and the assembly 6 makes the contact between the pressure beam 4 and the assembly 6 more uniform when the pressure beam 4 pushes the assembly 6, which can disperse the pressure and avoid damage to the assembly 6 due to excessive local pressure. At the same time, it can also better transmit the thrust, so that the assembly 6 can move smoothly when it is pushed, further improving the assembly quality.

[0025] In a preferred embodiment, each pressure beam 4 is evenly distributed around the collar 3, so that the thrust on the assembly 6 in the circumferential direction is evenly distributed, avoiding tilting or twisting of the assembly 6 due to uneven force distribution. This helps to ensure the stability of the posture of the assembly 6 during its movement toward the connecting plate 7, thereby ensuring the final assembly accuracy and installation quality of the coupling, and reducing equipment malfunctions that may be caused by assembly problems.

[0026] In a preferred embodiment, there are two pressure beams 4. Having two pressure beams 4 ensures that the assembly 6 can be provided with sufficient thrust to complete the assembly action, while simplifying the propulsion structure, reducing the number of parts, and lowering the manufacturing cost and maintenance difficulty of the tool. Moreover, the double pressure beam 4 structure makes it easy to achieve symmetrical force propulsion on the assembly 6, which is beneficial to maintaining the balance and stability of the assembly 6 during the propulsion process.

[0027] In a preferred embodiment, the length of the positioning shaft 1 is not less than 400 mm. This length provides sufficient depth after insertion into the positioning hole 71 of the connecting disc 7, enhancing the stability and reliability of the positioning. A longer positioning shaft 1 can better resist external force interference that may occur during assembly, further improving the stability of the connection between the installation tool and the connecting disc 7. This ensures that the entire assembly process revolves around a precise positioning datum, improving the accuracy of the coupling installation.

[0028] In a preferred embodiment, the end of the positioning shaft 1 furthest from the guide shaft 2 is chamfered. This chamfer guides the positioning shaft 1 when it is inserted into the positioning hole 71 of the connecting disc 7, making it easier to align and insert the positioning shaft 1 into the hole 71, reducing bumps and jamming during insertion, and improving the smoothness and efficiency of insertion. Simultaneously, the chamfer also avoids the risk of scratching or damaging other components due to the sharpness of the end of the positioning shaft 1, improving the safety of tool use.

[0029] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
