Description

Technical Field

[0001] This utility model relates to the field of shaft fittings technology, specifically an assemblable precision shaft fitting for an automotive engine. Background Technology

[0002] Precision shaft components for automotive engines refer to various shaft parts that play an important role in the engine. These components typically require high machining accuracy and durability to ensure the engine's performance and reliability. Precision shaft components are a very important part of machinery and industrial equipment. They are usually used to transmit motion and power and require high machining accuracy and durability.

[0003] An investigation revealed a Chinese utility model patent (Publication No.: CN217633405 U) disclosing a high-precision intermediate output shaft gear accessory. The accessory includes a connecting rod with a weight-reducing auxiliary rod at its front end. The auxiliary rod has a weight-reducing groove on its outer side and an installation accessory device at its front end. This device comprises an assembly assembly, a connecting shaft, and a connecting base assembly. The assembly assembly consists of an accessory shell, a protrusion, a placement groove, a placement slot, a connecting shell, a through hole, and a snap-fit ​​strip. One end of the snap-fit ​​strip is fixedly installed at the lower end of the connecting shell. In this high-precision intermediate output shaft gear accessory, after the protrusion and placement groove are snapped together, the connection between the accessory shell and the connecting shell is welded. Once the connecting shell and accessory shell are welded together, the assembly is installed. The snap-fit ​​reinforcement strengthens the weld between the accessory shell and the connecting shell, preventing detachment during use.

[0004] Although the aforementioned patent strengthens the weld between the accessory shell and the connecting shell by using a snap-fit ​​mechanism to prevent detachment during use, relying solely on a snap-fit ​​to secure the accessory means that if the snap-fit ​​falls off due to continuous vibration during use, the shaft accessory will become unusable, causing problems. It is also inconvenient to perform secondary reinforcement on the shaft accessory. If the first reinforcement becomes loose, there is still a second layer of reinforcement, which will not affect the normal use of the shaft accessory. Furthermore, installation is convenient and quick, and assembly is easy.

[0005] Therefore, this utility model provides an assemblable precision shaft accessory for automotive engines to solve the above-mentioned problems. Utility Model Content

[0025] 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.

[0026] This utility model provides an assemblable precision shaft accessory for automotive engines, such as... Figures 1-5 As shown, an assemblable precision shaft accessory for an automotive engine includes a connecting shaft 1, a connecting sleeve 2 fixedly connected to the bottom of the connecting shaft 1, and a snap-fit ​​mechanism fixedly connected to the bottom of the connecting sleeve 2.

[0027] The snap-fit ​​mechanism includes a plug plate 3, the upper surface of which is fixedly connected to the bottom of the connecting sleeve 2. A spring 4 is fixedly connected to the bottom of the plug plate 3, and a protrusion 5 is fixedly connected to one end of the spring 4. A rotating part 6 is fixedly connected to one side of the plug plate 3, and an extension plate 7 is fixedly connected to one end of the rotating part 6. A reinforcing mechanism is threaded onto the outer surface of the extension plate 7. When assembling precision shaft parts for automotive engines, the snap-fit ​​mechanism can be used to initially snap them in place. The extension plate 7 extends out of the connecting sleeve 2, and then the reinforcing mechanism is used to snap the shaft parts in place. At the same time as snapping, a second reinforcement is performed. If the shaft parts vibrate continuously during use, causing the snap-fit ​​mechanism to loosen, the reinforcing mechanism can still fix it in place, preventing the loosening of the snap-fit ​​mechanism from directly affecting the use of the shaft parts. This provides a second reinforcement to the shaft parts and will not affect their normal use. It is also convenient and quick to install and easy to assemble.

[0028] The reinforcement mechanism includes a threaded sleeve 8, the inner thread of which is connected to the outer surface of the extension plate 7. A threaded hole is provided on the outer surface of the threaded sleeve 8, and a reinforcement bolt 9 is connected to the inner thread of the threaded hole. A threaded groove is provided on the outer surface of the extension plate 7. The threaded sleeve 8 is screwed onto the extension plate 7 to fix the extension plate 7 and the threaded sleeve 8. Then, the reinforcement bolt 9 is fixed onto the threaded sleeve 8 to facilitate the fixation of the connecting sleeve 2. If the shaft fitting vibrates continuously during use, causing the locking mechanism to loosen, the reinforcement mechanism can still fix it, preventing the loosening of the locking mechanism from directly affecting the use of the shaft fitting, thus playing a secondary reinforcement role for the shaft fitting.

[0029] The connecting sleeve 2 is internally fixedly connected to a bearing 10, and the bearing 10 is internally fixedly connected to a connecting rod 11. The connecting rod 11 serves as an assembly tool, facilitating its assembly onto the car engine for use.

[0030] The bottom of the connecting sleeve 2 is snapped with a connector 12 by a plug plate 3. A sealing gasket 13 is snapped onto the upper surface of the connector 12. The sealing gasket 13 is fitted onto the bottom of the connecting sleeve 2 to increase the sealing performance of the shaft fitting, ensuring that oil, water or other liquids will not leak from the shaft fitting, which helps to maintain the normal operation of the system and avoids environmental pollution.

[0031] The inner wall of the connector 12 is provided with a groove, the diameter of which is adapted to the diameter of the protrusion 5. The groove in the connector 12 can hold the protrusion 5 in place, which facilitates the connection of the connecting sleeve 2 and the connector 12 for assembly.

[0032] The outer surface of the connecting rod 11 is provided with weight reduction grooves 14. There are four weight reduction grooves 14. The weight reduction grooves 14 can reduce the overall weight of the component. By reasonably designing the shape and position of the weight reduction grooves 14, the strength and rigidity of the component can be maintained or improved while reducing the weight, making the function of the shaft component more comprehensive. The design of the weight reduction grooves 14 can usually increase the surface area of ​​the shaft component, which helps to enhance heat dissipation.

[0033] Specifically, when assembling automotive engine shaft components, the connecting sleeve 2 is fixed to the bottom of the connecting shaft 1, and then the bearing 10 is installed inside the connecting sleeve 2. Next, the connecting rod 11 is installed inside the bearing 10 and onto the inner ring of the bearing 10. A sealing gasket 13 is fitted onto the bottom of the connecting sleeve 2 to increase the sealing of the shaft components, ensuring that oil, water, or other liquids do not leak from the shaft components, helping to maintain the normal operation of the system and avoiding environmental pollution. Then, the plug plate 3 is snapped onto the connector 12. Pressing the plug plate 3 downwards causes the protrusion 5 to be pressed downwards by the spring 4 into the groove of the connector 12, thus snapping the connecting sleeve 2 and the connector 12 into place. Finally, by rotating the rotating component 6, the extension plate 7 can be pulled outwards, securing the connector 12. Next, the extension plate 7 has a threaded groove on its outside. The threaded sleeve 8 is screwed onto the extension plate 7 to fix the extension plate 7 and the threaded sleeve 8. Then, the reinforcing bolt 9 is fixed onto the threaded sleeve 8 to facilitate the fixing of the connecting sleeve 2. If the shaft fitting vibrates continuously during use, causing the snap-fit ​​mechanism to loosen, the reinforcing mechanism can still fix it, preventing the loose snap-fit ​​mechanism from directly affecting the use of the shaft fitting. This provides secondary reinforcement to the shaft fitting and will not affect its normal use. It is also convenient and quick to install and easy to assemble. Subsequently, the weight reduction groove 14 can reduce the overall weight of the component. By reasonably designing the shape and position of the weight reduction groove 14, the strength and rigidity of the component can be maintained or improved while reducing the weight, making the function of the shaft fitting more comprehensive.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
