Description

Technical Field

[0001] This utility model relates to the field of locking mechanism technology, specifically a round tube locking mechanism for expansion sleeve processing. Background Technology

[0002] An expansion sleeve is a keyless connection device commonly used in mechanical engineering. It mainly consists of a pair of sleeves with tapered inner and outer surfaces. By tightening high-strength bolts, the inner and outer rings move axially relative to each other along the tapered surfaces, generating radial elastic deformation. This simultaneously creates a strong interference fit and friction between the inner surfaces of the mounting holes of the shaft and the hub, achieving a keyless and tight connection between the shaft and the hub. It reliably transmits torque, axial force, or a combination of both. When machining the outer surface of the expansion sleeve, a round tube locking mechanism is required to firmly clamp the corresponding components of the expansion sleeve.

[0003] However, in existing locking mechanisms, the locking sleeve experiences a reaction force from the expansion sleeve when a locking force is applied, which affects the stability of the locking sleeve. Therefore, those skilled in the art have provided a round tube locking mechanism for expanding sleeve machining to solve the problems mentioned in the background art. Utility Model Content

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.

[0022] Please see Figure 1-4 In this embodiment of the utility model, a round tube locking mechanism for expansion sleeve processing includes a fixing plate 1. The fixing plate 1 is characterized in that a fixing support sleeve 2 is fixed on the outside of the fixing plate 1, a guide post 3 penetrating the other side is fixed on one side of the fixing support sleeve 2, a return spring 4 is provided on the top of the fixing support sleeve 2, a reinforcing mechanism 5 is installed on the outside of the fixing plate 1, a locking sleeve 6 is connected to the top of the return spring 4, a rotating shaft 7 embedded inside is fixed on one side of the fixing plate 1, an eccentric locking wheel 8 is installed on the outside of the rotating shaft 7, one side of the eccentric locking wheel 8 is movably inserted into the inside of the fixing plate 1, and a stabilizing mechanism 9 is provided on the top of the fixing plate 1.

[0023] The stabilizing mechanism 9 includes a fixed housing 91. A support spring 92 is provided on the inner top wall of the fixed housing 91. A limit pad 93 is connected to the bottom of the support spring 92. A limit sleeve 94, penetrating the bottom of the limit pad 93, is fixed to the top of the limit pad 93. A guide threaded post 95 is installed on the top of the limit pad 93. A handle plate 96 is fixed to the top of the guide threaded post 95. A metal nut 97 is threaded onto the outer side of the guide threaded post 95. An arc-shaped groove is formed at the bottom of the limit sleeve 94, the size of which is adapted to the eccentric locking wheel 8. The fixed housing 91 and the fixed plate 1 are fixedly connected. The interior of the fixed plate 1 has a limit groove to accommodate the movement of the limit sleeve 94. When locking the outer surface of the expansion sleeve during processing, the corresponding expansion sleeve cylindrical shape... The component is placed between the locking sleeve 6 and the fixed support sleeve 2. Then, the operating handle on the outside of the eccentric locking wheel 8 is held and rotated. As the eccentric locking wheel 8 rotates, the locking sleeve 6 can be moved, allowing the locking sleeve 6 and the fixed support sleeve 2 to clamp and lock the expansion sleeve cylindrical component. Subsequently, the metal nut 97 on the outside of the guide thread post 95 can be rotated to release the limit on the guide thread post 95, and the support spring 92 in the fixed housing 91 provides elastic force to push the limit pad 93, so that the corresponding surface of the limit sleeve 94 fits against the eccentric locking wheel 8, which plays an auxiliary role in reinforcing and locking, providing a stable lateral support structure for the eccentric locking wheel 8, significantly increasing the rigidity of the entire locking structure, and helping to ensure the stability of the locking structure.

[0024] In one embodiment of this utility model, the reinforcement mechanism 5 includes a metal pad 51, a fixed threaded post 52 fixed to the outer side of the metal pad 51, a limit nut 53 threadedly connected to the outer side of the fixed threaded post 52, a limit bracket 54 fixed to the outer side of the fixing plate 1, a guide plate 55 installed on the outer side of the fixing plate 1, an anti-detachment slider 56 slidably connected to the guide plate 55 via a sliding groove, a movable connecting plate 58 fixed to one side of the anti-detachment slider 56, an mounting sleeve 57 installed on the outer side of the metal pad 51, and the movable connecting plate 58 penetrating the mounting sleeve 57, the metal pad 51, and the fixed plate 54. The fixed support sleeve 2 is fixedly connected. After the fixed support sleeve 2 and the fixed plate 1 are fixedly connected, the metal pad 51 on the outside of the fixed support sleeve 2 is in contact with the fixed plate 1. Then, the anti-detachment slider 56 is pushed to move the movable connecting plate 58, so that the movable connecting plate 58 passes through the mounting sleeve 57 and is movably sleeved on the outside of the fixed threaded post 52. Finally, the limit nut 53 is threadedly connected to the fixed threaded post 52 to easily fix the position of the movable connecting plate 58 and to provide auxiliary reinforcement to the connection between the fixed support sleeve 2 and the fixed plate 1.

[0025] The working principle of this utility model is as follows: This device is equipped with a stabilizing mechanism 9. When locking the outer surface of the expansion sleeve during processing, the corresponding cylindrical expansion sleeve component is placed between the locking sleeve 6 and the fixed support sleeve 2. Then, the operating handle on the outside of the eccentric locking wheel 8 is held and rotated. As the eccentric locking wheel 8 rotates, it can drive the locking sleeve 6 to move, allowing the locking sleeve 6 and the fixed support sleeve 2 to clamp and lock the cylindrical expansion sleeve component. Subsequently, rotating the metal nut 97 on the outside of the guide thread post 95 can release the limit on the guide thread post 95, and allow the support spring 92 in the fixed housing 91 to provide elastic force to push the limiting pad 93, so that the corresponding surface of the limiting sleeve 94 fits against the eccentric locking wheel 8, which plays an auxiliary role in reinforcing and locking the eccentric locking wheel. 8 provides a robust lateral support structure, significantly increasing the rigidity of the entire locking structure and helping to ensure its stability. With the reinforcement mechanism 5, after the fixed support sleeve 2 and the fixed plate 1 are fixedly connected, the metal pad 51 on the outside of the fixed support sleeve 2 is in contact with the fixed plate 1. Then, the anti-detachment slider 56 is pushed to move the movable connecting plate 58, allowing the movable connecting plate 58 to pass through the mounting sleeve 57. The movable connecting plate 58 is movably sleeved on the outside of the fixed threaded post 52. Finally, the limit nut 53 is threadedly connected to the fixed threaded post 52, which conveniently completes the fixing of the position of the movable connecting plate 58 and can provide auxiliary reinforcement to the connection between the fixed support sleeve 2 and the fixed plate 1, ensuring that the fixed support sleeve 2 is stable and does not loosen.

[0026] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
