Description

Technical Field

[0001] This utility model relates to a locking structure for the turntable of a fully automatic winding machine, belonging to the field of winding machine technology. Background Technology

[0002] Fiber optic reels are carriers used for winding long-distance optical fibers and are an indispensable type of reel for packaging optical fiber products at the factory. They are now generally standardized in the industry. However, depending on the application and characteristics of various optical fibers, some fiber optic reels need to be customized. Furthermore, because optical fibers have small outer diameters and long distances, their length and arrangement must be rewound using winding equipment or fiber splitting and rewinding equipment during use. Therefore, fixing the fiber optic reel on a rotating disk or shaft is particularly important.

[0003] For example, utility model patent CN216411678U discloses a fiber optic disc locking device for a winding machine, including a fastening body. One end of the fastening body is provided with an extended shaft, and a rotatable rotating head is sleeved on the extended shaft. The rotating head has a conical structure and is used to tighten the fiber optic disc. The other end of the fastening body is provided with a locking sleeve and a compression sleeve. The locking sleeve is provided with an extended cylinder, and the compression sleeve is provided with an inner hole. The inner hole is sleeved with the extended cylinder and is used to compress the extended cylinder. The extended cylinder is used to sleeve with a fixed shaft. This device solves the problem of axial locking of the fiber optic disc when the fiber optic disc of the winding machine adopts a rotating disc connection.

[0004] However, the above solution has the following shortcomings in practical use:

[0005] 1. The outer cylinder has multiple grooves along its circumference to enhance elasticity. However, frequent compression and release will cause metal fatigue and wear on the edges of the grooves. After long-term use, the shrinkage and clamping ability of the outer cylinder will gradually decrease. The hard contact of the conical surface (without lubrication design) will cause wear on the conical surface due to frequent friction, further reducing the fitting accuracy.

[0006] 2. The compression sleeve squeezes the locking sleeve by rotating the thread, but there is no quantitative standard for its locking force. It depends entirely on the operator's feel. If the force is too small, the locking will not be secure and the fixed shaft will slip with the locking sleeve. If the force is too large, it may over-compress the outer cylinder, causing permanent deformation or damage to the surface of the fixed shaft. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a locking structure for the turntable of a fully automatic winding machine, which realizes lubrication of the extension cylinder, avoids long-term contact wear, and adds a clamping and limiting mechanism between the recessed groove and the protrusion, which facilitates manual observation of the threaded connection and avoids over-tightening or under-tightening.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] A locking structure for a turntable in a fully automatic winding machine includes a turntable connecting mechanism and a pressing and fixing mechanism disposed on one side thereon, a drive shaft passing through the turntable connecting mechanism and connected to the pressing and fixing mechanism. The turntable connecting mechanism has a connecting seat with a protrusion formed on one side wall of the connecting seat. The pressing and fixing mechanism has a pressing sleeve with a recessed groove on its side wall. The recessed groove and the protrusion are detachably connected, and a through hole is formed on the inner wall of the recessed groove. A locking sleeve that can be inserted into the through hole is disposed in the protrusion. The locking sleeve and the through hole are slidably engaged. The drive shaft passes through the locking sleeve. A lubrication mechanism is disposed in the pressing sleeve and communicates with the through hole.

[0010] In this solution, the lubrication mechanism connects to the through hole (the mating part of the locking sleeve and the compression sleeve), which can continuously supply lubricating oil to the tapered mating surface, avoiding wear caused by hard friction of the tapered surface in the prior art, extending the service life of the component and maintaining the mating accuracy.

[0011] The detachable connection between the protrusion and the recess provides installation space for the subsequent addition of a limiting structure (such as a clamping limiting mechanism). From a structural design perspective, it avoids the defect of "simply relying on the feel of the thread for locking" and lays the foundation for quantifying the locking force and avoiding being too loose or too tight.

[0012] Preferably, the lubrication mechanism includes: an annular groove formed inside the extrusion sleeve, the annular groove being arranged around the outside of the through hole, and at least one strip groove being provided between the annular groove and the through hole; an oil supply pipe is also provided on the side wall of the extrusion sleeve, one end of the oil supply pipe being connected to the annular groove, and the other end being connected to the oil outlet of an external lubricating oil delivery device.

[0013] In this solution, the background technology does not mention a lubrication structure. Existing devices suffer from rapid wear of the conical surface and decreased fitting accuracy due to the lack of continuous lubrication.

[0014] The annular groove surrounds the through hole, and together with the strip groove, it guides the lubricating oil from the annular groove to the inner wall of the through hole (conical mating surface), ensuring that there are no dead corners in lubrication coverage and avoiding wear caused by insufficient lubrication in certain areas.

[0015] The oil pipeline is directly connected to the external lubricating oil delivery equipment, which can achieve continuous or periodic replenishment of lubricating oil without disassembling the locking structure, reducing maintenance difficulty and adapting to the continuous operation requirements of fully automatic winding machines.

[0016] Preferably, multiple strip grooves are provided and are distributed at equal angles around the outside of the through hole, and each strip groove is connected to the through hole and the annular groove.

[0017] In this design, the equally angled strip grooves can synchronously and evenly deliver the lubricating oil in the annular groove to the entire conical mating surface of the through hole, avoiding excessive local wear caused by differences in lubrication volume, and ensuring long-term stable mating accuracy between the locking sleeve and the extrusion sleeve.

[0018] The evenly distributed grooves do not disrupt the structural symmetry of the extrusion sleeve while supplying oil, thus avoiding uneven stress caused by local lubrication differences during locking and improving the overall stability of the locking structure.

[0019] Preferably, the locking sleeve includes: a mounting groove formed on the side wall of the protrusion, an annular ring disposed in the mounting groove, and an extension cylinder integrally formed on the side wall of the annular ring away from the protrusion, the extension cylinder being conical, and the through hole being a conical hole adapted to the extension cylinder, and a plurality of grooves being formed at equal angles around the outer peripheral wall of the extension cylinder, one end of each groove being connected to the side wall of the extension cylinder away from the annular ring.

[0020] In this design, the extension cylinder adopts a conical structure, combined with the design of "the groove connecting the end away from the annular ring", so that the deformation of the extension cylinder during extrusion is concentrated at the free end (the annular ring away from the fixed end), reducing stress concentration at the fixed end, reducing the metal fatigue rate at the edge of the groove, and extending the clamping capacity life of the extension cylinder.

[0021] The fit between the tapered extension cylinder and the tapered through hole can work synergistically with the aforementioned lubrication mechanism. Lubricating oil enters the tapered mating surface through the strip groove, which reduces wear and lowers deformation resistance through lubrication, thus avoiding permanent deformation caused by hard extrusion and solving the problem of "excessive extrusion causing damage" in the prior art.

[0022] Preferably, a force-sharing hole is also provided on the outer wall of the extension cylinder on one side of each of the cutting grooves. The force-sharing hole is connected to one end of the cutting groove, and the diameter of the force-sharing hole is greater than the width of the cutting groove.

[0023] In this solution, in the background technology, the existing grooves of the extended cylinder are prone to cracking due to stress concentration, which exacerbates fatigue failure.

[0024] The diameter of the force-distributing hole is larger than the width of the groove and is connected to the end of the groove. This can effectively disperse the stress at the end of the groove (the end of the groove is the core area of ​​stress concentration), avoid cracks or fatigue fractures at the edge of the groove during frequent extrusion, significantly improve the fatigue resistance of the extension cylinder, and extend its service life.

[0025] It should be noted that the force-dividing holes only act on stress concentration points and do not damage the overall elastic deformation function of the groove. This ensures that the extension cylinder can still reliably shrink and tighten through the groove when locking, thus solving the fatigue problem without affecting the locking effect.

[0026] Preferably, a plurality of clamping and limiting mechanisms are also provided around the through hole in the recessed groove. The clamping and limiting mechanisms include: a sleeve fixed to the inner sidewall of the recessed groove, a chamber formed in the sleeve, a sliding plate slidably connected in the chamber, a protrusion extending to the outside of the sleeve fixed to the sidewall of the sliding plate, a spring provided in the chamber on the side of the sliding plate away from the protrusion, a rolling groove formed in the end of the protrusion, a ball rolled in the rolling groove, a guide groove formed in the inner sidewall of the chamber, a guide block slidably connected in the guide groove, and the guide block and the sliding plate fixedly connected.

[0027] In this design, when the protrusion is connected to the recessed groove (such as a threaded connection), the protrusion presses against the surface of the protrusion under the action of the spring. As the connection is tightened, the protrusion pushes the protrusion to compress the spring. When it is tightened to the correct position, the displacement of the protrusion or the contact state of the ball can be quantitatively judged by external observation (such as a scale) (or when the guide block moves to the end of the guide groove and the spring can no longer be compressed), thus avoiding the problem of being too loose or too tight due to "relying on feel".

[0028] The rolling connection of the balls reduces friction between the protrusions and the bumps, preventing jamming during connection. At the same time, multiple clamping and limiting mechanisms are distributed around the through hole to assist in the coaxial positioning of the protrusions and the recessed grooves, ensuring connection accuracy, reducing local wear caused by eccentric locking, and further improving structural stability.

[0029] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0030] 1. An annular groove is opened inside the extrusion sleeve around the through hole. Multiple equally angled strip grooves guide the lubricating oil to the conical mating surface (the contact area between the through hole and the extension cylinder), ensuring that there are no dead corners in lubrication and avoiding excessive wear caused by insufficient lubrication in some areas. The lubricating oil not only reduces friction and wear, but also reduces the deformation resistance when the extension cylinder and the through hole are extruded, avoiding damage to the conical surface caused by hard contact, maintaining the fitting accuracy of the two in the long term, and ensuring locking stability.

[0031] 2. The extension cylinder adopts a conical structure, with grooves evenly distributed along the outer circumference and connected to the free end of the extension cylinder (the end away from the annular ring). This concentrates deformation at the free end, reduces stress concentration at the fixed end (at the annular ring), lowers the metal fatigue rate at the groove edge, and extends the service life of the clamping capacity. Each groove has an additional force-distributing hole with a diameter larger than the groove width on one side, which can effectively disperse the stress at the groove end (the core area of ​​stress concentration), preventing cracks or fractures in the groove during frequent extrusion, further improving the fatigue resistance of the extension cylinder, and reducing downtime maintenance due to component failure.

[0032] 3. The protrusion of the limiting mechanism presses against the surface of the protrusion under the action of the spring. When the protrusion is connected to the recessed groove (such as a thread), the protrusion pushes the protrusion to compress the spring. The operator can judge the tightness by the displacement of the protrusion, replacing the "pure feel" operation and avoiding being too loose or too tight. Attached Figure Description

[0044] 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.

[0045] Please see Figure 1-4 This utility model provides a technical solution:

[0046] A locking structure for a turntable in a fully automatic winding machine includes a turntable connecting mechanism 1 and a pressing and fixing mechanism 2 disposed on one side thereon, and a drive shaft 3 that passes through the turntable connecting mechanism 1 and is connected to the pressing and fixing mechanism 2. The turntable connecting mechanism 1 has a connecting seat 11, and a protrusion 12 is formed on one side wall of the connecting seat 11. The pressing and fixing mechanism 2 has a pressing sleeve 21, and a recessed groove 22 is provided on the side wall of the pressing sleeve 21. The recessed groove 22 and the protrusion 12 are detachably connected, and a through hole 23 is also provided on the inner wall of the recessed groove 22. A locking sleeve 24 that can be inserted into the through hole 23 is provided in the protrusion 12. The locking sleeve 24 and the through hole 23 are slidably engaged. The drive shaft 3 passes through the locking sleeve 24. A lubrication mechanism 4 is also provided in the pressing sleeve 21 and is connected to the through hole 23.

[0047] Specifically, this device improves upon the friction problem between the extrusion sleeve 21 and the extension cylinder 242 based on the reference document (utility model patent with announcement number CN216411678U, "A locking device for fiber optic discs of a winding machine"). A lubrication mechanism 4 is added to lubricate the outer wall of the extension cylinder 242, avoiding wear on the surface of the extension cylinder 242 caused by long-term hard friction. At the same time, the structure of the groove 243 is improved and a force-dividing hole 244 is added to avoid cracking when the extension cylinder 242 is deformed. Furthermore, a clamping and limiting mechanism 5 is installed at the connection between the recessed groove 22 and the protrusion 12. When the protrusion 12 is inserted into the recessed groove 22 to a certain depth, the protrusion 54 is squeezed into the chamber 52 and cannot go any deeper, thus providing resistance to the protrusion 12 and preventing manual tightening of the protrusion 12. At this point, it means that the protrusion 12 is screwed into the recessed groove 22 to the specified depth, ensuring the tightness of the threaded connection.

[0048] The turntable connecting mechanism 1 in this device also has: an extension shaft set on the other side wall of the connecting seat 11, the extension shaft and the protrusion 12 are arranged opposite to each other, and a through hole communicating with the protrusion 12 is opened on the side wall of the extension shaft. The through hole is adapted to the outer diameter of the transmission shaft 3, and a rotating joint is rotatably sleeved on the outside of the extension shaft through a bearing. The turntable body is connected to the outside of the rotating joint. The turntable body is sleeved on the outside of the transmission shaft, and a limiting plate can also be fixed on the transmission shaft. The limiting plate abuts against the turntable body and is located on the side away from the rotating joint.

[0049] Specifically, when installing the locking sleeve 24, first insert the annular ring 241 of the locking sleeve 24 into the mounting groove on the side wall of the protrusion 12 to ensure that the annular ring 241 is fixedly fitted to the protrusion 12. At this time, the extension cylinder 242 integrally formed by the annular ring 241 extends out of the outside of the protrusion 12. The tapered structure of the extension cylinder 242 is adapted to the tapered through hole 23 of the extrusion sleeve 21, and the groove 243 on the outer periphery of the extension cylinder 242 faces the end away from the annular ring 241.

[0050] Align the protrusion 12 with the recessed groove 22 of the extrusion sleeve 21, and gradually connect the two by rotating the thread. During the process, the extension cylinder 242 is gradually inserted into the through hole 23, and the clamping and limiting mechanism 5 in the recessed groove 22 starts to work—the protrusion 54 presses against the surface of the protrusion 12 under the elastic force of the spring 55, and the ball 541 rolls with the rotation of the protrusion 12 to reduce frictional resistance; the sliding plate 53 slides along the cavity 52, and the guide block 561 moves synchronously in the guide groove 56 to ensure the stable movement of the protrusion 54.

[0051] The drive shaft 3 is sequentially passed through the connecting seat 11, protrusion 12 and locking sleeve 24 of the turntable connecting mechanism 1 until it is connected to the power input end of the pressing and fixing mechanism 2, thus completing the assembly of the overall structure.

[0052] Furthermore, the lubrication mechanism 4 includes: an annular groove 41 formed in the extrusion sleeve 21, the annular groove 41 being arranged around the outside of the through hole 23, and at least one strip groove 42 being provided between the annular groove 41 and the through hole 23; an oil supply pipe 43 is also provided on the side wall of the extrusion sleeve 21, one end of the oil supply pipe 43 being connected to the annular groove 41, and the other end being connected to the oil outlet of an external lubricating oil delivery device.

[0053] Specifically, the external lubricating oil delivery equipment delivers lubricating oil to the annular groove 41 inside the extrusion sleeve 21 through the oil delivery pipe 43. Since the annular groove 41 is arranged around the through hole 23 and is connected to the through hole 23 through multiple equally angled strip grooves 42, the lubricating oil will flow evenly along the strip grooves 42 to the conical inner wall of the through hole 23.

[0054] Lubricating oil adheres to the tapered mating surface of the through hole 23 and the extension cylinder 242, forming a lubricating film. When the extension cylinder 242 slides or deforms under pressure within the through hole 23, the lubricating film effectively reduces the hard friction between the two, avoids wear on the tapered surface, and reduces deformation resistance, preventing permanent deformation of the extension cylinder 242 due to hard pressure.

[0055] Furthermore, multiple strip grooves 42 are provided and are distributed at equal angles around the outside of the through hole 23, and each strip groove 42 is connected to the through hole 23 and the annular groove 41.

[0056] Furthermore, the locking sleeve 24 includes: a mounting groove formed on the side wall of the protrusion 12, an annular ring 241 disposed in the mounting groove, and an extension cylinder 242 integrally formed on the side wall of the annular ring 241 away from the protrusion 12. The extension cylinder 242 is conical, and the through hole 23 is a conical hole adapted to the extension cylinder 242. Multiple grooves 243 are formed at equal angles around the outer peripheral wall of the extension cylinder 242, and one end of each groove 243 is connected to the side wall of the extension cylinder 242 away from the annular ring 241.

[0057] Furthermore, a force-sharing hole 244 is also provided on the outer wall of the extension cylinder 242 on one side of each groove 243. The force-sharing hole 244 is connected to one end of the groove 243, and the diameter of the force-sharing hole 244 is greater than the width of the groove 243.

[0058] Furthermore, a plurality of clamping and limiting mechanisms 5 are provided around the through hole 23 within the recessed groove 22. The clamping and limiting mechanism 5 includes: a sleeve 51 fixed to the inner sidewall of the recessed groove 22; a chamber 52 is provided inside the sleeve 51; a sliding plate 53 is slidably connected inside the chamber 52; a protrusion 54 extending to the outside of the sleeve 51 is fixedly connected to the sidewall of the sliding plate 53; a spring 55 is provided in the chamber 52 on the side of the sliding plate 53 away from the protrusion 54; a rolling groove is provided in the end of the protrusion 54; a ball bearing 541 is slidably connected in the rolling groove; a guide groove 56 is also provided on the inner sidewall of the chamber 52; a guide block 561 is slidably connected in the guide groove 56; and the guide block 561 and the sliding plate 53 are fixedly connected.

[0059] Specifically, when the protrusion 12 and the recess 22 are tightened by threads, the through hole 23 of the compression sleeve 21 exerts a radial compression force on the extension cylinder 242. Since the extension cylinder 242 has a groove 243, and the end of the groove 243 is connected to the force-distributing hole 244, the extension cylinder 242 will contract and deform along the groove 243, tightly gripping the drive shaft 3, thus achieving synchronous rotation and locking of the turntable and the drive shaft 3. The force-distributing hole 244 can disperse the stress at the end of the groove 243, preventing frequent deformation from causing cracks or metal fatigue at the edge of the groove 243.

[0060] As the protrusion 12 tightens into the recess 22, the protrusion 12 pushes the protrusion 54 to compress the spring 55, and the sliding plate 53 gradually moves deeper into the chamber 52. When the guide block 561 slides to the end of the guide groove 56, the sliding plate 53 can no longer move, and the protrusion 54 generates significant resistance to the protrusion 12. At this point, the operator can determine that the thread has been tightened to the preset position, avoiding permanent deformation of the extension cylinder 242 due to over-tightening, or slippage between the drive shaft 3 and the locking sleeve 24 due to insufficient tightening.

[0061] The workflow of this embodiment is as follows:

[0062] The connecting seat 11 of the turntable connecting mechanism 1 is detachably connected (threaded connection) to the extrusion sleeve 21 of the extrusion fixing mechanism 2 through the protrusion 12. The drive shaft 3 passes through the connecting seat 11, the protrusion 12 and the locking sleeve 24 and then docks with the extrusion fixing mechanism 2. As the protrusion 12 and the extrusion sleeve 21 are tightened, the protrusion 12 pushes the protrusion 54 to compress the spring 55, the sliding plate 53 slides along the chamber 52, and the guide block 561 moves synchronously in the guide groove 56. When the guide block 561 slides to the end of the guide groove 56, the sliding plate 53 can no longer move, and the protrusion 54 generates obvious resistance to the protrusion 12. At this time, it means that the locking is in place, and the operator can stop tightening to avoid excessive extrusion that may cause permanent deformation of the extension cylinder, or insufficient tightening that may cause the drive shaft and the locking sleeve to slip.

[0063] An external lubricating oil delivery device delivers lubricating oil to the annular groove 41 inside the extrusion sleeve 21 through the oil delivery pipe 43. The annular groove 41 surrounds the through hole 23. The lubricating oil is evenly distributed to the conical inner wall of the through hole 23 through multiple equally angled strip grooves 42. The lubricating oil adheres to the conical mating surface between the through hole 23 and the extension cylinder 242 of the locking sleeve 24, forming a continuous lubricating film. This reduces the frictional resistance when the two slide or are squeezed relative to each other, while also reducing the wear rate and maintaining the mating accuracy.

[0064] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
