Description

Technical Field

[0001] This utility model relates to the field of CNC lathe electric spindle technology, and in particular to a spindle that is easy to disassemble and assemble. Background Technology

[0002] Easy-to-disassemble spindles are core transmission components that optimize the installation and disassembly process. They are used in fields such as mechanical manufacturing and automated equipment. While retaining the functions of ordinary spindles in transmitting power and driving loads, they solve the problems of cumbersome and time-consuming disassembly and assembly and high requirements for professional operation of traditional spindles through structural innovation. They are suitable for frequent maintenance, replacement of parts or flexible production scenarios. With quick-release connection and modular bearing housing design, they have become a necessity in high-frequency maintenance equipment, machine tools that require multiple product switching, small household tools and equipment in harsh environments. They can reduce costs, improve efficiency and reduce barriers to entry. Today, they are gradually becoming standard equipment in relevant scenarios. The core components of the easy-to-disassemble spindle are designed around optimizing disassembly and assembly efficiency. Based on the ordinary spindle, key structures are improved, and each part is deeply integrated with the characteristics of easy disassembly and assembly. It includes the spindle body, which is mostly made of high-precision metal shafts with wear-resistant surface treatment. It not only ensures the function of transmitting torque and bearing load, but also reduces disassembly and assembly obstacles through optimized design. The quick-release connection structure is the core of easy disassembly and assembly, replacing traditional bolts in various forms. It can be quickly connected or separated without complicated tools. The modular bearing assembly integrates related structures, which can be operated as a whole during disassembly and assembly. The positioning auxiliary structure can help to quickly align the position, and there are also auxiliary disassembly and assembly components to further reduce the difficulty of operation. In existing technologies, when a spindle fixing mechanism that is easy to disassemble and install is in operation, if its quick-release connection structure adopts a snap-fit ​​or tapered self-locking design, after long-term exposure to the torque and vibration generated by the equipment transmission, the connection part is prone to slight displacement. Subsequent disassembly and assembly require manual calibration of the displacement deviation before docking can be completed. Although the modular bearing assembly integrates seals and lubrication structures, the contact surface between the assembly and the spindle body is prone to the accumulation of dust or grease residue under long-term load. The contact surface needs to be cleaned additionally during disassembly and assembly, otherwise it will affect the accuracy after reassembly. If the positioning pins or guide grooves of the positioning auxiliary structure are not treated with anti-wear, the positioning accuracy will decrease due to wear after repeated disassembly and assembly, thereby prolonging the time required for subsequent alignment and installation. Therefore, a spindle that is easy to disassemble and install is proposed to solve the above problems. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a spindle that is easy to disassemble and assemble, aiming to improve the problems of easy displacement of quick-release structures, accumulation of residue in bearing components, and easy wear of positioning structures in the prior art, which lead to inconvenience in disassembly and assembly.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a spindle that is easy to assemble and disassemble, comprising a shaft body, a fixing ring fixedly connected to one side of the shaft body, a connector fixedly connected to one side of the fixing ring, and a fixing mechanism fixedly connected to one side of the connector. The fixing mechanism includes a rotating housing, the inner side of which is slidably connected to the outer side of the connector, a connecting block one slidably connected to the inner side of the rotating housing, a connecting block two slidably connected to the inner side of the rotating housing, a limiting ring one slidably connected to the inner side of the rotating housing, a spring fixedly connected to one side of the limiting ring one, and a rotating component fixedly connected to the other side of the spring. As a further description of the above technical solution: The rotating assembly includes a second limiting ring, one side of which is fixedly connected to one side of the spring, a fixed head is fixedly connected to one side of the second limiting ring, and a third connecting block is fixedly connected to the top of the fixed head. As a further description of the above technical solution: The outer side of the first connecting block is fixedly connected to the top of the connector, and the outer side of the second connecting block is fixedly connected to the bottom of the connector; As a further description of the above technical solution: One side of the limiting ring is slidably connected to one side of the connector, and the outer side of the spring is slidably connected to the inner side of the rotating housing. As a further description of the above technical solution: The inner side of the fixing ring is fixedly connected to the outer side of the shaft, and the connecting block is slidably connected to the inner side of the rotating housing. As a further description of the above technical solution: The outer side of the limiting ring two is slidably connected to the inner side of the rotating housing, and the outer side of the fixing head is rotatably connected to the inner side of the rotating housing.

[0009] 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.

[0010] Example: A spindle that is easy to assemble and disassemble, see reference Figures 1 to 3The system includes a spindle body 1, which is made of high-strength alloy material, which can improve the overall load-bearing capacity and wear resistance of the spindle, ensure stability during high-speed operation, and meet the long-term use requirements of the equipment. A retaining ring 2 is fixedly connected to one side of the spindle body 1. The retaining ring 2 can enhance the connection stability between the spindle body 1 and the connector 3, prevent the two from loosening during assembly or operation, and ensure the structural strength of the connection part. A connector 3 is fixedly connected to one side of the retaining ring 2. As a key structure connecting the spindle body 1 and external components, the connector 3's precise size design can reduce assembly gaps and improve the alignment efficiency during spindle assembly and disassembly. A fixing mechanism 4 is fixedly connected to one side of the connector 3. The fixing mechanism 4 can realize the quick locking and unlocking of the spindle and external components, which is the core structure that improves the ease of spindle assembly and disassembly. Specifically, during assembly, connector 3 quickly aligns with external components using precise dimensions, reducing gaps to ensure initial connection accuracy. Shaft 1 is securely connected to connector 3 via retaining ring 2, preventing loosening during assembly. Once connector 3 is aligned with external components, fixing mechanism 4 activates to quickly lock and complete assembly. During disassembly, fixing mechanism 4 first unlocks, releasing the spindle from the external components, and then quickly separates connector 3 from the external components using precise alignment. Retaining ring 2 maintains the stability of shaft 1 and connector 3 throughout the assembly and disassembly process, ensuring the structure remains stable.

[0011] The fixing mechanism 4 includes a rotating housing 41. The rotating housing 41 drives the internal components to move together, providing an operating platform for locking and unlocking the fixing mechanism 4 and simplifying the assembly and disassembly steps. The inner side of the rotating housing 41 is slidably connected to the outer side of the connector 3. This sliding fit allows the rotating housing 41 to move flexibly, facilitating the adjustment of the locking state of the fixing mechanism 4. A first connecting block 42 is slidably connected to the inner side of the rotating housing 41. The first connecting block 42 can engage with the slot of the external component under the action of the rotating housing 41, achieving initial fixing and laying the foundation for subsequent complete locking. A second connecting block 43 is slidably connected to the inner side of the rotating housing 41. The second connecting block 43 works in conjunction with the first connecting block 42 to fix the external component from different directions. To improve the locking stability of the fixing mechanism 4, a limit ring 44 is slidably connected to the inner side of the rotating housing 41. The limit ring 44 can limit the sliding range of the connecting block 42 and the connecting block 43, preventing the parts from slipping out of the preset track due to excessive sliding, and ensuring the normal operation of the fixing mechanism 4. A spring 45 is fixedly connected to one side of the limit ring 44. The spring 45 can provide elastic restoring force, pushing the limit ring 44 and the connecting block 42 and the connecting block 43 to reset when unlocking, which facilitates the quick disassembly of the spindle. A rotating component 46 is fixedly connected to the other side of the spring 45. The rotating component 46 can cooperate with the rotating housing 41 to transmit rotational force. At the same time, the elasticity of the spring 45 buffers the impact force during disassembly and assembly, protecting the parts from damage. Specifically, when the fixing mechanism 4 is locked, the rotating housing 41 slides and rotates along the connector 3, causing the connecting block 42 and the connecting block 43 to slide synchronously, so that they cooperate with the slot of the external component. The limiting ring 44 restricts the sliding range of the two to prevent them from deviating from the track. At the same time, the rotating housing 41 is linked to the rotating component 46, and the spring 45 is compressed to store elastic force. When unlocking, the rotating housing 41 is rotated in the opposite direction, and the rotating component 46 cooperates to transmit force. The spring 45 releases elastic force to push the limiting ring 44 to reset, thereby causing the connecting block 42 and the connecting block 43 to disengage from the slot. The rotating housing 41 slides back along the connector 3 to complete the unlocking. The spring 45 can also buffer the impact force of disassembly and assembly.

[0012] Reference Figures 2 to 4 The rotating assembly 46 includes a second limiting ring 461, which is made of wear-resistant metal and can precisely limit the axial displacement of the rotating assembly 46, ensuring stable cooperation of each component during linkage. One side of the second limiting ring 461 is fixedly connected to one side of the spring 45. This connection method can stably transmit the elastic force of the spring 45 to the second limiting ring 461, ensuring the reliable realization of the reset function. A fixing head 462 is fixedly connected to one side of the second limiting ring 461. The fixing head 462 can enhance the connection strength between the second limiting ring 461 and the rotating housing 41, preventing them from colliding relative to each other. If the rotation becomes loose, a connecting block 3 463 is fixedly connected to the top of the fixing head 462. The connecting block 3 463 can cooperate with the inner structure of the rotating shell 41 to improve the stability of the rotational force transmission and ensure the synchronization of operation. The outer side of the connecting block 1 42 is fixedly connected to the top of the connecting head 3. This fixing method can keep the connecting block 1 42 in a fixed position when subjected to force, ensuring precise engagement with external components. The outer side of the connecting block 2 43 is fixedly connected to the bottom of the connecting head 3, forming a symmetrical fixing structure with the connecting block 1 42, further improving the overall stability of the fixing mechanism 4. Specifically, the rotating outer shell 41 rotates, and its inner side engages with the connecting block 3 463. The fixing head 462 drives the limiting ring 2 461 to rotate synchronously, compressing the spring 45. Meanwhile, connecting blocks 1 42 and 2 43, fixed to the connecting head 3, remain stationary, engaging with the rotating outer shell 41 for secure locking. During unlocking, the spring 45 rebounds, pushing the limiting ring 2 461 back to its original position. The fixing head 462 and connecting block 3 463 then drive the rotating outer shell 41 to rotate in the opposite direction. The limiting ring 2 461 precisely limits axial displacement, and the connecting blocks 1 42 and 2 43 are symmetrically fixed vertically, ensuring component stability during the unlocking process without loosening or shifting.

[0013] One side of the limiting ring 44 is slidably connected to one side of the connector 3. This sliding design allows the limiting ring 44 to move flexibly with the extension and retraction of the spring 45, ensuring that the limiting effect on the connecting block can be dynamically adjusted. The outer side of the spring 45 is slidably connected to the inner side of the rotating housing 41, which can guide the spring 45 to extend and retract in a preset direction, preventing it from shifting or twisting under force and extending its service life. The inner side of the fixing ring 2 is fixedly connected to the outer side of the shaft 1. The tight fixing enhances the integrity of the shaft 1 and the fixing ring 2 and prevents relative wobbling during high-speed operation. The connecting block 463 is slidably connected to the inner side of the rotating housing 41 and can slide flexibly with the rotation of the rotating housing 41, ensuring that the linkage response between the rotating component 46 and the housing is rapid. The outer side of the limiting ring 461 is slidably connected to the inner side of the rotating housing 41, which can reduce the frictional resistance when the two move relative to each other, making the operation more effortless and smooth. The outer side of the fixing head 462 is rotatably connected to the inner side of the rotating housing 41. This rotational cooperation can realize the relative movement between the rotating housing 41 and the fixing head 462, providing a structural basis for locking and unlocking operations. Specifically, when locked, the rotating outer shell 41 rotates, its inner side slides and engages with the connecting block 3 463 and the fixed head 462, causing the limiting ring 2 461 to slide along the inner side of the outer shell, compressing the spring 45. The spring 45 extends and retracts directionally along the inner side of the outer shell, and the limiting ring 1 44 slides along the connecting head 3 with the spring 45, limiting the displacement of the connecting block. When unlocked, the spring 45 rebounds, causing the limiting ring 2 461 to reset, the rotating outer shell 41 rotates in the opposite direction, the connecting block 3 463 slides with it, and the fixed ring 2 is fixed to the shaft 1 to prevent shaking during high-speed operation and ensure overall stability.

[0014] The implementation principle of this application embodiment is as follows: When the shaft 1 needs to be installed with the machine tool, it can be quickly positioned and securely connected through the fixing mechanism 4. The core components of the fixing mechanism 4 include a rotating housing 41, a connecting block 42, a connecting block 43, a limiting ring 44, and a spring 45. The rotating housing 41 has a pre-set matching groove on its inner side, the size of which is precisely matched with the connecting blocks 42 and 43 on the outer side of the connector 3, ensuring guidance and sealing during installation. During installation, the connector 3 is aligned with the groove of the rotating housing 41 and pushed in. After the connector 3 enters the inner side, it will squeeze the limiting ring 44. The spring 45 is forced to contract, providing space for the rotation of the connecting block. At this time, the shaft 1 is rotated, causing the connector 3 to rotate synchronously, so that the connecting block 42 is aligned with the groove of the rotating housing 41. Then the spring 45 rebounds, pushing the limit ring 44 to reset, firmly locking the connecting block 42 into the groove, forming a mechanical locking structure, which realizes the rigid fixation of the shaft 1 and the machine tool, effectively preventing axial movement and radial displacement during operation. If disassembly is required, the shaft 1 is rotated in the opposite direction, so that the connecting block 42 is disengaged from the groove limit. At the same time, the connector 3 is pressed to compress the spring 45, and the connector 3 can be pulled out to complete the unlocking.
