Description
Technical Field
[0001] This utility model relates to the field of hook needle technology for winding machines, specifically a device for free rotation of hook needles in winding machines. Background Technology
[0002] A winding machine is a device that winds a thread-like object onto a specific workpiece, typically used for winding copper wire. Its main function is to wind conductors onto corresponding workpieces, such as coil frames, according to specific process requirements. The performance and precision of the winding machine directly affect the quality and performance of the final product, and the hook, as the core component directly involved in the winding operation, plays a crucial role in the winding effect through its working state and flexibility.
[0003] Traditional hook devices for winding machines have many limitations. During the winding process, the hook is usually fixed in a specific position and angle, making it difficult to dynamically adjust according to the actual winding action. When faced with workpieces of different shapes and sizes and diverse winding process requirements, the fixed hook angle cannot match the winding action well, resulting in an inflexible winding process. Therefore, a free rotation device for the hook of a winding machine is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a device for the free rotation of the hook of a winding machine, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for free rotation of hook needles in a winding machine, comprising a winding machine body, a worktable on one side of the winding machine body, a lifting module on the lower side of the worktable, two needle bars on one side of the lifting module, and a hook needle body integrally formed on the top of the needle bars;
[0006] The lifting module is used to control the up-and-down reciprocating movement of the needle bar and the hook body;
[0007] The needle bar is provided with a rotating component on one side for the needle bar and hook body to rotate freely, and the lifting module is connected to a connecting plate at its moving end, with a connecting component on one side of the connecting plate;
[0008] The rotating assembly includes a housing, a limit frame is fixed to the inner wall of the housing, and a bearing is embedded in the inner wall of the limit frame;
[0009] The connecting assembly includes two fixed frames, a connecting frame, and a prompting mechanism. A locking groove is provided on one side of the connecting frame, and a first sliding groove and a second sliding groove are respectively provided inside the fixed frame.
[0010] Preferably, the inner ring of the bearing is fixedly sleeved on the outside of the needle bar, one side of the housing is fixed to one side of the connecting frame, the connecting frame is L-shaped, a hook groove is provided on one side of the hook body, and one end of the connecting frame is inserted into the inside of the second sliding groove.
[0011] Preferably, the first slide groove is slidably connected to a slide plate, a ventilation hole is provided on one side of the slide plate, and a pull rod and a locking rod are fixed on both sides of the slide plate respectively.
[0012] Preferably, the pull rod is fitted with a spring on its outer side, and the two ends of the spring are respectively connected to one side of the slide plate and the first slide groove.
[0013] Preferably, one side of the fixing bracket is fixed to one side of the connecting plate. When the locking rod is inserted into the inner side of the locking groove, the hook body is in the installed state. When the locking rod leaves the inner side of the locking groove, the hook body is in the disassembled state.
[0014] Preferably, the above-mentioned prompting mechanism includes a limiting block, a connecting rod that movably passes through one side of the limiting block, and a protrusion and a push plate that are fixed on both sides of the connecting rod, respectively.
[0015] Preferably, the connecting rod is fitted with a tension spring on its outer side, and the two ends of the tension spring are respectively connected to one side of the protrusion and the limiting block. One side of the limiting block is fixed to the inner wall of the second slide groove.
[0016] When one end of the connecting frame abuts against one side of the push plate, the protrusion protrudes from one side of the fixing frame.
[0017] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:
[0018] 1. Under the action of the rotating component, the hook body can dynamically adjust its angle to follow the rotation direction of the magnetic ring, so that the hook body can better cooperate with the winding action, making the winding process more flexible and precise. The needle bar can rotate freely in the bearing, allowing the hook body to rotate freely, which can fully meet the requirements of different angles of the hook body during the winding process, and improve the adaptability of the equipment to different winding scenarios and processes.
[0019] Second, during installation, simply insert the connecting bracket into the second sliding groove. The spring force will drive the sliding plate to slide, causing the locking rod to automatically engage with the locking groove. No additional tools or complicated operations are required, significantly shortening the installation time. During disassembly, simply pull the lever. The lever will drive the sliding plate to overcome the spring force, and the locking rod will disengage from the locking groove. There is no need to disassemble complex parts, and the operation can be completed by a single person, significantly improving maintenance efficiency. It avoids the tedious process of repeatedly tightening screws required by traditional bolt fixing methods. Both disassembly and installation are relatively simple, thus greatly shortening maintenance time and improving the overall operating efficiency of the equipment.
[0020] Third, the bumps provide clear operational feedback, allowing operators to more accurately judge the insertion and removal status of the connector, thereby avoiding misoperation due to misjudgment and preventing the hook body from starting to work before the connector is correctly inserted. Operators do not need to spend extra time confirming the status of the connector; they only need to observe the position of the bumps. This reduces misoperation, improves the safety and stability of the equipment, and lowers the risk of equipment failure or safety accidents caused by misoperation. Attached Figure Description

[0031] Example
[0032] Please see Figure 1-6 This utility model provides a technical solution: a device for the free rotation of the hook of a winding machine, including a winding machine body 1, a worktable 5 on one side of the winding machine body 1, a lifting module 7 on the lower side of the worktable 5, two needle bars 2 on one side of the lifting module 7, and a hook body 9 integrally formed on the top of the needle bar 2; when the winding machine body 1 is started, the lifting module 7 drives the connecting plate 8 to move vertically and reciprocally, driving the needle bar 2 and the hook body 9 to insert / exit the coil according to a preset trajectory, and the hook groove hooks the wire and winds it evenly.
[0033] The lifting module 7 is used to control the up-and-down reciprocating motion of the needle bar 2 and the hook body 9; the lifting module 7 drives the needle bar 2 and the hook body 9 to reciprocate vertically to complete the winding action; a rotating component 6 for the needle bar 2 and the hook body 9 to rotate freely is provided on one side; a connecting plate 8 is connected to the moving end of the lifting module 7; the lifting module 7 can be a linear module; a connecting component 3 is provided on one side of the connecting plate 8.
[0034] The rotating assembly 6 includes a housing 61, with a limiting frame 62 fixed to the inner wall of the housing 61, and a bearing 63 embedded in the inner wall of the limiting frame 62. The rotating assembly 6 enables the needle bar 2 to rotate freely through the bearing 63, reducing friction and ensuring the uniformity of winding. When the needle bar 2 is driven to rotate by the winding machine body 1, the bearing 63 converts sliding friction into rolling friction, significantly reducing wear. At the same time, the limiting frame 62 prevents axial movement and ensures smooth rotation. The inner ring of the bearing 63 is fixedly sleeved on the outer side of the needle bar 2. The needle bar 2 is provided with a shoulder structure, which works with an elastic retaining ring to achieve axial positioning. One side of the housing 61 is fixed to one side of the connecting frame 35, and a hook groove is provided on one side of the hook body 9.
[0035] The connecting assembly 3 includes two fixing brackets 31, a connecting bracket 35, and a prompting mechanism. A locking groove 38 is provided on one side of the connecting bracket 35, and a first sliding groove 36 and a second sliding groove 37 are respectively provided inside the fixing brackets 31. The connecting bracket 35 is L-shaped, with one end inserted into the inner side of the second sliding groove 37. A sliding plate 32 is slidably connected to the inner side of the first sliding groove 36. A vent is provided on one side of the sliding plate 32 to balance air pressure and prevent jamming. A pull rod 34 and a locking rod 39 are fixed to both sides of the sliding plate 32, respectively. A spring 33 is sleeved on the outer side of the pull rod 34, and both ends of the spring 33 are respectively connected to one side of the sliding plate 32 and the first sliding groove 36. When the connecting bracket 35 is inserted into the second sliding groove 37, the locking groove 38 on its side aligns with the locking rod 39 of the sliding plate 32. The spring 33 pushes the sliding plate 32 to slide along the first sliding groove 36, causing the locking rod 39 to insert into the locking groove 38, thus completing the mechanical locking.
[0036] One side of the fixing bracket 31 is fixed to one side of the connecting plate 8. When the locking rod 39 is inserted into the inside of the locking groove 38, the hook body 9 is in the installation state. When the locking rod 39 leaves the inside of the locking groove 38, the hook body 9 is in the disassembly state. Pulling the pull rod 34 causes the slide plate 32 to compress the spring 33, and the locking rod 39 exits the locking groove 38. The inner wall of the locking groove 38 is provided with a wedge-shaped inclined surface.
[0037] The prompting mechanism includes a limiting block 313, with a connecting rod 310 extending through one side of the limiting block 313. A protrusion 311 and a push plate 314 are fixed to both sides of the connecting rod 310, respectively. A tension spring 312 is sleeved on the outer side of the connecting rod 310, with both ends of the tension spring 312 connected to one side of the protrusion 311 and the limiting block 313, respectively. One side of the limiting block 313 is fixed to the inner wall of the second slide groove 37. When one end of the connecting frame 35 abuts against one side of the push plate 314, the protrusion 311 protrudes from one side of the fixed frame 31. The bottom of the connecting frame 35 pushes the push plate 314, causing the protrusion 311 to protrude from the side of the fixed frame 31 via the connecting rod 310, providing visual feedback and prompting the user that the hook can be safely removed.
[0038] In its initial state, the tension spring 312 conceals the protrusion 311 within the fixing frame 31. When the connecting frame 35 is fully inserted into the second slide groove 37, the push plate 314 is pushed to its limit position, and the protrusion 311 protrudes from one side of the fixing frame 31. During disassembly, after the connecting frame 35 is withdrawn, the tension spring 312 resets, and the tension spring 312 drives the push plate 314 to retract via the connecting rod 310, causing the protrusion 311 to retract into the inside of the fixing frame 31.
[0039] In this embodiment, the winding machine body 1 is a model PY-2505 manufactured by Dongguan Pinyuan Automation Technology Co., Ltd. Since the structure and operating principle of this model of winding machine body 1 are existing technologies, its structure and operating principle will not be described in detail here. The vulnerable parts in this embodiment are regularly inspected, maintained and replaced.
[0040] Working principle: The magnetic ring is installed on the spindle clamp of the worktable 5, and one end of the wire is fixed. The main spindle motor of the winding machine body 1 is started (not shown in the figure), which drives the magnetic ring to rotate. The wire enters the winding area through the wire supply system and maintains constant tension under the action of the tension control system. The wire laying system evenly winds the wire onto the magnetic ring according to the preset laying spacing. Under the up-and-down movement of the hook body 9, the wire forms a spiral coil on the outside of the magnetic ring. The worktable 5 is provided on one side of the winding machine body 1, and the lifting module 7 is provided on the lower side of the worktable 5. After the lifting module 7 is started, its moving end will drive the connecting plate 8 to move up and down. Since the needle bar 2 and the hook body 9 are connected to the connecting plate 8 through the connecting component 3, when the connecting plate 8 moves up and down, the needle bar 2 and the hook body 9 will also move up and down to meet the needs of different height positions of the hook body 9 during the winding process.
[0041] The needle bar 2 rotates freely within the bearing 63, thereby enabling the hook body 9 to rotate freely and meet the different angle requirements of the hook body 9 during the winding process. Under the action of the rotating component 6, the hook body 9 can dynamically adjust its angle following the rotation direction of the magnetic ring, so that the tension of the wire is uniform during the coil winding process, and it is not easy for the wire to loosen or break.
[0042] When the connecting frame 35 is installed, one end of the connecting frame 35 is inserted into the inner side of the second slide groove 37. At this time, under the action of the spring 33, the slide plate 32 slides in the first slide groove 36, so that the locking rod 39 is inserted into the inner side of the locking groove 38, thereby fixing the connecting frame 35 on the fixing frame 31, so that the hook body 9 is in the installation state and can participate in the winding work normally.
[0043] When it is necessary to disassemble the hook body 9, pull the lever 34. The lever 34 causes the slide plate 32 to slide within the first slide groove 36, overcoming the elastic force of the spring 33, so that the locking lever 39 moves away from the inside of the locking groove 38. The connecting bracket 35 can then be pulled out from the second slide groove 37. The hook body 9 is now in a disassembled state, which facilitates maintenance, replacement, and other operations on the hook body 9.
[0044] The protrusion 311 of the prompting mechanism provides clear operational feedback, reducing the risk of human error. When one end of the connecting frame 35 is inserted into the second slide groove 37, the connecting frame 35 will abut against one side of the push plate 314, pushing the push plate 314 and the connecting rod 310 to move, thereby causing the protrusion 311 to protrude from one side of the fixed frame 31, indicating to the operator that the connecting frame 35 has been correctly inserted and the hook body 9 is in the installed state. When the connecting frame 35 is pulled out, under the action of the tension spring 312, the connecting rod 310 and the push plate 314 are reset, and the protrusion 311 no longer protrudes, indicating to the operator that the connecting frame 35 has been pulled out and the hook body 9 is in the disassembled state.
[0045] In summary, under the action of the rotating component 6, the hook body 9 can dynamically adjust its angle to follow the rotation direction of the magnetic ring, enabling the hook body 9 to better cooperate with the winding action, making the winding process more flexible and precise. The needle bar 2 rotates freely within the bearing 63, allowing the hook body 9 to rotate freely, which can fully meet the different angle requirements of the hook body 9 during the winding process, and improve the adaptability of the equipment to different winding scenarios and processes.
[0046] During installation, simply insert the connecting bracket 35 into the second slide groove 37. The elastic force of the spring 33 will drive the slide plate 32 to slide, causing the locking rod 39 to automatically engage with the locking groove 38. No additional tools or complicated operations are required, significantly shortening the installation time. During disassembly, simply pull the pull rod 34. The pull rod 34 will drive the slide plate 32 to overcome the elastic force of the spring 33, and the locking rod 39 will disengage from the locking groove 38. No complex parts need to be disassembled, and the operation can be completed by a single person, significantly improving maintenance efficiency. It avoids the tedious process of repeatedly tightening screws required by traditional bolt fixing methods. The disassembly and installation processes are relatively simple, thus greatly shortening maintenance time and improving the overall operating efficiency of the equipment.
[0047] The protrusion 311 provides clear operational feedback, allowing operators to more accurately determine the insertion and removal status of the connector 35. This avoids misoperation due to misjudgment and prevents the hook body 9 from starting to work before the connector 35 is correctly inserted. Operators do not need to spend extra time confirming the status of the connector 35; they only need to observe the position of the protrusion 311. This reduces misoperation, improves the safety and stability of the equipment, and lowers the risk of equipment failure or safety accidents caused by misoperation.
