Description

Technical Field

[0001] This application relates to the field of wire processing technology, and in particular to a winding machine with automatic straightening and cutting functions. Background Technology

[0002] Winding machines are one of the core pieces of equipment in the field of electrical component manufacturing, playing a crucial role, especially in the coil winding process of products such as motors, transformers, and inductors. Among them, the flying fork winding machine, with its high speed and high efficiency, has become the preferred solution for the mass production of small and medium-sized coils.

[0003] A typical fly fork winding machine mainly consists of the following key components: The fly fork winding head, as the core working unit, is usually U-shaped or symmetrical arm-shaped, with an internal motor driving the main shaft, causing the fly fork body to rotate at high speed. A wire hook (or wire guide) is installed at the end of the fly fork arm, which directly guides the wire. Its material often has wear-resistant or ceramic properties to protect the wire. To ensure the tightness and consistency of the wound coil, a tension control system (usually including felt, brake pads, or electronic tensioners) provides constant and appropriate tension during the unwinding process. The workpiece to be wound (such as a stator core, transformer frame, etc.) usually has a central through hole. During processing, its central through hole is fitted onto a positioning mold, and it is placed in the processing position by a fixture mounted on the fly fork body. The wire arrangement system (such as a servo motor-driven lead screw mechanism) causes axial displacement of the fly fork or mold during the winding process to achieve neat arrangement of multiple layers of coil. During operation, the wire is led out from the spool, passes through the tension control system, and then enters the wire nozzle of the fly fork. Driven by the drive unit, the fly fork rotates at high speed around its axis, causing the wire nozzle and the wire to move in a circular motion, thereby regularly winding the wire onto the workpiece fixed in the mold, completing the winding of the main coil. The entire process is centrally managed by the control system (commonly using a programmable logic controller (PLC) and a human-machine interface (HMI), which can preset and precisely execute process parameters such as the number of turns, speed, and wire laying mode.

[0004] Although existing fly fork winding technology is highly automated, a significant bottleneck still exists at the end of the actual production process: the post-processing of the lead wire taps. After the winding machine completes the preset number of turns, the starting and ending ends of the lead wire (collectively referred to as "tap" or "lead wire") are led out from the bobbin. These taps are usually in a free-hanging state, or irregularly wrapped around the fly fork arm, mold, or wound coil due to inertia and residual tension, presenting a messy, bent, tangled, and irregularly positioned form.

[0005] This irregular tap state cannot meet the requirements of subsequent processes. Before entering the station for welding, plugging or connecting with other circuits, these taps must be additionally arranged, that is, the "straightening" operation, to keep them straight, with determined orientation, and usually they also need to be cut to a specified length according to process requirements. At present, this key post-processing step is heavily dependent on manual work or independent semi-automatic equipment. Operators need to manually free messy taps from the winding state, straighten and position them, and then cut them with auxiliary tools. This not only greatly reduces the overall production efficiency and prolongs the production tact of a single product, but also, due to the uncontrollability of manual operation, it is difficult to ensure the consistency of tap length, straightness and spatial position, which directly affects the yield of subsequent automatic welding or assembly and the stability of the electrical performance of the product. This link has become a prominent shortboard restricting the coherence of the production line and the improvement of the full automation level. Summary of the Invention

[0006] In order to improve the problems existing in the above-mentioned technology, the present application provides a winding machine with functions of automatically straightening and cutting taps.

[0007] A winding machine with functions of automatically straightening and cutting taps provided by the present application adopts the following technical solution: A winding machine with functions of automatically straightening and cutting taps, comprising a frame; a positioning mechanism, wherein the positioning mechanism comprises a positioning shaft rotatably arranged in the frame; a wire fixing mechanism arranged in the frame and used for fixing a wire end of a wire; a material pressing mechanism, wherein the material pressing mechanism comprises a material pressing shaft movably arranged in the frame, the material pressing shaft can move in a direction close to the positioning shaft to press a workpiece onto the positioning shaft, and a tap wire hanging seat is arranged on the material pressing shaft; a wire cutting mechanism arranged on one side of the tap wire hanging seat; a flyer mechanism, wherein the flyer mechanism comprises a flyer base movably arranged in the frame, the flyer base can reciprocate between the positioning shaft and the tap wire hanging seat, a loading clamp for taking and placing the workpiece is arranged on the flyer base, and a winding head for pulling the wire and winding the wire onto the workpiece is rotatably arranged on the flyer base.

[0008] By adopting the above technical solution, through the sequential coordinated action of the positioning mechanism, the pressing mechanism, the flying fork mechanism and the wire cutting mechanism, the wire tapping is sorted, straightened and precisely cut in an integrated and automated manner while completing the conventional winding, thereby completely eliminating the efficiency bottleneck and quality fluctuation caused by the reliance on manual post-processing in the traditional process. The working process and coordination of each component are as follows: Before winding, the wire fixing mechanism first activates to reliably fix the starting end (wire end) of the wire, thus establishing a tension reference point for subsequent winding, allowing the winding head to effectively wind the wire by pulling it. When winding the workpiece, the workpiece to be wound is fixed on the fly fork base by the loading clamp. The fly fork base operates to drive the loading clamp, which then transports the workpiece to be wound onto the positioning shaft. The positioning shaft first provides radial reference and axial support for the workpiece. Subsequently, the pressure shaft moves along the direction close to the positioning shaft, pressing and fixing the workpiece onto the positioning shaft, forming a stable winding environment. The tap hook seat integrated at its front end provides a pre-set hooking and positioning point for the wire end. Winding begins... After the winding head rotates to pull the wire for winding, once the winding of one working surface of the workpiece is completed, the fork base drives the winding head to move towards the tap holder along a preset trajectory. The tap portion of the wire on the workpiece is actively guided and hung on the tap holder. The winding head uses its reciprocating traction force to tighten the wire tap, which is in a slack or bent state between two points, thus straightening the wire tap portion. After this, the positioning shaft rotates to drive the workpiece to rotate, thereby causing each working surface of the workpiece to connect with the winding head in sequence. Each working surface of the workpiece can be wound according to the above process. After the overall winding of the workpiece is completed, the wire cutting mechanism set on one side of the tap holder actuates to cut the tap on the tap holder, thus obtaining a straight lead end. Throughout the process, the various mechanisms are closely integrated in terms of space and action sequence, enabling winding, tapping guidance, mechanical straightening, and synchronous cutting to be completed in a continuous automated cycle. This not only significantly improves the production cycle and consistency of individual products, but also realizes unmanned continuous operation from winding to finished product, effectively solving the technical problems of manual labor, low efficiency, and uneven quality in the post-tap processing of the background technology.

[0009] Optionally, a pressure frame is provided inside the frame, and the pressure shaft is rotatably mounted on the pressure frame. A pressure drive is provided inside the frame to drive the pressure frame to move in a direction close to or away from the positioning shaft. The tap wire hanging seat includes a fixed seat mounted on the pressure shaft, and multiple sets of wire hanging parts are arranged circumferentially on the fixed seat. Each set of wire hanging parts includes two spaced wire hanging plates, and a wire cutting gap is formed between the two wire hanging plates. The wire cutting mechanism is movably mounted inside the frame, and its movement path is configured to feed the cutting blade into or out of the wire cutting gap.

[0010] By adopting the above technical solution, after the workpiece is conveyed onto the positioning shaft, the pressure drive drives the pressure frame to move as a whole, thereby driving the pressure shaft and the tap wire holder on it to be precisely positioned. Simultaneously, the pressure shaft presses the workpiece onto the positioning shaft, and the fixed seat and multiple sets of wire hanging parts arranged circumferentially on it also reach the working position. Afterwards, the rotation of the positioning shaft causes the workpiece to rotate, and the multiple circumferentially spaced working surfaces on the workpiece rotate and sequentially align with the winding head, thus completing the winding of each working surface in sequence. The pressure shaft is rotatably mounted on the pressure frame; therefore, when the positioning shaft... When the workpiece rotates, the pressure shaft is driven to rotate synchronously, and the fixed seat rotates synchronously as well. Multiple sets of wire-hanging sections are arranged circumferentially on the fixed seat; their number may be less than or equal to the number of working surfaces of the workpiece, thus achieving a configuration where multiple working surfaces correspond to one set of wire-hanging sections. During winding, after completing the winding of one working surface, the winding head can guide the taps from that working surface to the corresponding set of wire-hanging sections, hanging them between two spaced-apart wire-hanging plates. When the positioning shaft rotates to send the next working surface to the winding position, the winding head can again guide the newly generated taps to the same set or the next set of wire-hanging sections. The wire-cutting gap formed between the two sets of wire-hanging plates provides a unified cutting channel for all taps hung in that set. After all winding and tap hanging are completed, the wire-cutting mechanism moves along its preset path, sequentially or simultaneously sending the cutting blades into the wire-cutting gaps of each wire-hanging section, thus cutting multiple taps converging in the same gap at once, or sequentially cutting all taps within the gaps. Throughout the process, the circumferentially arranged hanging section covers the circumference of the workpiece, and the cutting gap serves as a unified cutting window. Together with the precisely movable cutting mechanism, it enables the batch and high-precision cutting of the collected taps.

[0011] Optionally, the hanging plate is provided with a winding groove, and the two hanging plates of each group of hanging parts are arranged opposite each other, and the winding grooves on the two hanging plates are positioned opposite each other to form a conductor space.

[0012] By adopting the above technical solution, the winding groove defines a stable conductor space between two opposing hanging plates. Taps are precisely introduced into this space, and the groove walls provide radial constraint and circumferential positioning for the flexible conductors from both sides, preventing them from slipping out or swaying laterally. When the same hanging section needs to receive multiple taps from multiple working surfaces, these subsequent taps are also guided into this same conductor space. Because the channel formed by the winding groove has clear guidance, multiple conductors can maintain a parallel and orderly parallel arrangement within this space, avoiding tangling, crossing, or piling. In the subsequent straightening process, the reciprocating tension of the winding head acts evenly on each tap through this conductor space, causing it to be straightened synchronously. Finally, when the shearing blade of the wire cutting mechanism enters the wire cutting gap between the two hanging plates (this gap is connected to or partially overlaps with this "conductor space"), all the taps constrained within the conductor space and neatly arranged can be cut cleanly and completely in one go. Throughout the process, the "conductor space" formed by the relatively arranged winding slots provides a fully integrated management channel for multiple taps, from introduction, aggregation, constraint to sorting.

[0013] Optionally, the positioning shaft is provided with a positioning seat for docking with the center through hole of the workpiece, and the pressing shaft is provided with a receiving cavity for accommodating the positioning seat.

[0014] By adopting the above technical solution, during the workpiece loading stage, the loading fixture transports the workpiece to the positioning shaft. The positioning seat passes through the central through hole of the workpiece, thereby completing the initial radial and circumferential positioning of the workpiece. After the positioning seat extends out after passing through the central through hole of the workpiece, the pressure shaft moves in the direction of the positioning shaft to perform the pressing action. During this process, the receiving cavity at the front end of the pressure shaft can precisely accommodate the extended positioning seat, allowing the end face of the pressure shaft to directly press against the end face of the workpiece without interference, while the extended part of the positioning seat is embedded in the receiving cavity. This design ensures that when the pressure shaft applies axial pressing force, its force application point acts directly on the workpiece body, avoiding the potential for uneven load or deformation of the positioning seat caused by indirect pressure transmission through the positioning seat. At the same time, the receiving cavity provides precise clearance space for the positioning seat, preventing rigid collision between the pressure shaft and the positioning shaft during axial pressing, and ensuring that the final pressing state of the workpiece is stable and reliable, providing a solid reference for subsequent high-speed, high-precision winding. In addition, the cooperation between the positioning seat and the receiving cavity allows the pressure shaft to rotate more smoothly and synchronously with the positioning shaft, and the multiple hanging parts can better connect with each working surface of the workpiece.

[0015] Optionally, the loading clamp includes two loading clamps disposed opposite to each other on the fork base, the two loading clamps being movable in a direction toward or away from each other to clamp or release the workpiece; the fork base is provided with an abutment seat located between the two loading clamps, the abutment seat being movable in a direction toward or away from the positioning axis, and the fork base is also provided with an elastic element for providing a biasing force toward the positioning axis to the abutment seat; the positioning mechanism further includes a positioning wedge movably disposed within the frame, the positioning wedge being disposed on the side of the positioning axis away from the abutment seat, the positioning wedge being movable in a direction toward the positioning axis.

[0016] By adopting the above technical solution, after the initial loading and pressing are completed, the winding cycle begins. The positioning shaft rotates, driving the workpiece to rotate. When the workpiece rotates to switch to the next working surface, the positioning wedge located on the side of the workpiece away from the winding head actively moves and rigidly abuts against the end face of the workpiece on that side, providing a stable axial positioning reference, accurately counteracting the axial movement that may be caused by rotational repositioning, and ensuring that the new working surface is accurately stopped at the working position of the winding head. At the same time, the abutment seat located on the other side of the workpiece, under the continuous bias pressure of the elastic element, always maintains flexible abutment against the end face of the workpiece. The loading clamp does not completely retract, but maintains slight contact with the upper and lower ends of the workpiece, providing auxiliary radial constraint. When the winding head performs the winding action, the fly fork base will drive the loading clamp, abutment seat, etc. on it to retract slightly according to the set program. At this point, the elastic abutment seat plays a crucial role in buffering and following up: it undergoes slight compression under elastic action, yet maintains contact and pressure on the workpiece, thereby compensating in real time for any slight axial displacement of the workpiece that may be caused by winding tension, equipment vibration, or base retraction. This ensures that the workpiece is always stably "suspended" and clamped between the rigid reference surface of the positioning wedge and the elastic surface of the abutment seat. Throughout the winding process, the positioning wedge actively "aligns" and provides a hard reference each time it changes position, while the elastic abutment seat acts as a "follow-up damper," continuously providing adaptive clamping force to eliminate axial clearance and suppress vibration. Together, they achieve dynamic precision and active vibration reduction throughout the entire winding process.

[0017] Optionally, the wire-setting mechanism includes a winding post and a pressing plate. The winding post is disposed on the pressing shaft and is used for winding the wire end of the conductor. The pressing plate is movably disposed at the end of the winding post away from the pressing shaft. The pressing plate can move in a direction close to or away from the pressing shaft to press and release the wire end of the conductor.

[0018] By adopting the above technical solution, before winding begins, the wire end is initially wound around the winding post (simply two or three turns). Then, the pressure plate moves towards the pressure shaft, pressing the wire end firmly against it to prevent it from coming loose when the winding head pulls the wire under significant tension, thus providing a stable starting tension point for winding. When winding is complete and the tapping process is finished, and it is necessary to release the wire end to remove the workpiece or proceed to the next cycle, the pressure plate moves away from the pressure shaft, thereby releasing the pressure on the wire end. Afterward, the pressure shaft moves away from the positioning axis, and the winding post is driven to move synchronously, allowing the wire end, no longer under pressure, to detach from the winding post. This process, through a simple mechanical combination of the "winding post" and the "movable pressure plate," achieves a secure, reliable, and easy-to-operate fixation and release of the wire end.

[0019] Optionally, an anti-detachment seat is provided on one side of the wire fixing mechanism, and an anti-detachment clamp is movably provided on the anti-detachment seat. The anti-detachment clamp can move in a direction close to or away from the anti-detachment seat to press down the wire end of the conductor. After the wire end of the conductor is pressed onto the anti-detachment seat by the anti-detachment clamp, it is pulled by the winding head to be wound around the winding post.

[0020] By adopting the above technical solution, the anti-detachment seat and anti-detachment clamp jointly construct an efficient "wire transfer and pre-processing station," connecting the operation cycles of two workpieces and realizing automatic handover, pre-storage, and pre-processing of wire ends, thereby minimizing the non-winding waiting time of the equipment. Its working process is as follows: 1. Cycle Start and First Workpiece Winding: For the first workpiece, the wire end is first placed in the anti-detachment seat position and clamped and fixed by the anti-detachment clamp; then, the winding head pulls the wire, winding it around the winding post to establish winding tension; the anti-detachment clamp can then be released, and the winding head begins to perform the winding operation for the first workpiece. 2. Cross-Cycle Connection: When the winding of the first workpiece is about to be completed, after completing the processing of the last tap (straightening and splicing), the winding head does not immediately cut or remain idle, but instead actively moves to the anti-detachment seat carrying a reserved length of wire; at this time, the anti-detachment clamp activates, pre-clamping and fixing this wire end belonging to the next workpiece onto the anti-detachment seat. 3. Wire Cutting and Cycle Restart: After the wire end of the next workpiece is fixed by the anti-detachment clamp, the equipment can cut the wire connecting the two workpieces at the wire cutting mechanism on one side of the tap hanging seat. At this point, the winding operation of the first workpiece is completely completed (finished product off the line), and the winding operation of the second workpiece is ready (wire end fixed). When the second workpiece is loaded and pressed, the winding head can directly hook the pre-stored wire end from the anti-detachment seat, pull and wrap it around the winding column, and start winding immediately without any additional time for finding, threading or fixing the wire end.

[0021] The above structure sets the "anti-detachment seat + anti-detachment clamp" as a fixed wire transfer station, so that after the winding head finishes one workpiece, it can immediately "pre-store the wire end" for the next workpiece. This eliminates the production cycle waste caused by wire end processing (grabbing, fixing, cutting) when changing workpieces in traditional equipment, and realizes continuous production.

[0022] Optionally, the pressing shaft includes a pressing fixed shaft movably disposed within the frame, a pressing movable shaft coaxially slidably connected to the pressing fixed shaft, a first driving part disposed on the pressing fixed shaft for driving the pressing movable shaft to move in a direction away from or close to the pressing fixed shaft, the tap hanging seat disposed on the pressing fixed shaft, and the pressing movable shaft for pressing the workpiece onto the positioning shaft.

[0023] By adopting the above technical solution, when initially setting or changing product specifications, the winding machine first drives the pressure shaft to extend or retract relative to the pressure fixed shaft according to the required tap length of the workpiece, thereby changing the effective working length of the entire pressure shaft assembly (the pressure shaft assembly is formed by the cooperation of the pressure shaft and the pressure fixed shaft). Since the tap holder is fixedly set on the pressure fixed shaft, its position is relatively fixed, while the pressing end face of the pressure shaft acting on the workpiece is determined by the end face of the extendable pressure shaft. Therefore, when the pressure shaft extends, after the entire pressure shaft assembly presses the workpiece onto the positioning shaft, the axial distance between the workpiece and the tap holder will increase accordingly; conversely, when the pressure shaft retracts, this distance will decrease. After winding is completed, the tap is led out from the workpiece and hung on the tap holder; this distance directly determines the reserved length of the tap's "straight section". Subsequently, the fork base performs a reciprocating motion to straighten the tap, and the wire cutting mechanism cuts it. Throughout the process, the precise control of the travel of the pressing shaft by the first drive unit enables stepless and digital adjustment of the distance between the workpiece and the wire holder, thereby directly and linearly controlling the length of the final tap. This solution integrates the length adjustment function into the pressing shaft that performs the pressing action, realizing an efficient, precise, and compact tap length adjustment solution. There is no need to add an independent adjustment module or replace parts. Different length specifications can be quickly switched through the program, thereby improving the overall applicability of the winding machine while ensuring adjustment accuracy and ease of operation.

[0024] Optionally, the positioning shaft includes a positioning fixed shaft seat rotatably disposed within the frame, and a positioning movable shaft seat detachably connected to the positioning fixed shaft seat via a first connecting part. A plurality of positioning arc plates are slidably disposed on the positioning movable shaft seat, and a second driving part is disposed on the positioning movable shaft seat. The second driving part is used to drive the plurality of positioning arc plates to expand radially along the positioning movable shaft seat to tighten the workpiece or contract to loosen the workpiece. The positioning movable shaft seat is detachably connected to the pressure shaft via the second connecting part.

[0025] By adopting the above technical solution, before winding begins, the workpiece is fitted around the retracted positioning arc plate through its central through hole. The second drive unit activates, driving all positioning arc plates to expand radially outward synchronously, uniformly and precisely tightening the inner hole of the workpiece from the inside, forming a gapless rigid positioning and drive connection. At this time, the positioning movable shaft is integrated with the workpiece through the positioning arc plate. During winding, the rotational power of the positioning fixed shaft is transmitted to the positioning movable shaft through the first connecting part, thereby driving the tightened workpiece to rotate at high speed and smoothly, allowing the winding head to accurately complete the winding operation. After winding is completed, the second drive unit drives all positioning arc plates to retract radially inward, making their overall outer diameter smaller than the inner diameter of the workpiece's central through hole, thus automatically releasing the tightening lock on the workpiece. At this point, under the influence of gravity, the workpiece slides down along the length of the multiple positioning arc plates that remain in its central through hole. Subsequently, the pressure shaft (connected to the positioning movable shaft seat via the second connecting part) drives the entire positioning movable shaft seat to move away from the positioning fixed shaft seat, thereby completely removing the positioning movable shaft seat from the loosened workpiece's inner hole, leaving unobstructed operating space for the robot or other material handling equipment. Throughout the entire work cycle, the radially extendable positioning arc plates form an "intelligent chuck," providing extremely high rigidity positioning and drive during winding, and automatically releasing after winding to facilitate unloading. The linkage between the positioning movable shaft seat and the pressure shaft enables the positioning module to automatically switch and avoid obstacles between the winding station and the unloading station, thus achieving seamless and automated connection between the winding and unloading processes, significantly improving the production cycle time.

[0026] Optionally, the first connecting part includes a first connecting block, which is disposed on the positioning movable shaft seat and is non-cylindrical. The positioning fixed shaft seat has a connecting groove, the shape of which is adapted to the shape of the first connecting block and is used for the insertion of the first connecting block. The second connecting part includes a first connecting seat disposed on the positioning movable shaft seat and a second connecting seat disposed on the pressure shaft. The first connecting seat has a connecting hole, the second connecting seat has a second connecting block, and the pressure shaft has a third driving part for driving the second connecting block to be inserted into the connecting hole.

[0027] By adopting the above technical solution, when connecting the positioning fixed shaft seat and the positioning movable shaft seat through the first connecting part, the non-cylindrical first connecting block at the tail end of the positioning movable shaft seat is inserted into the connecting groove. The shape of the connecting groove matches the shape of the first connecting block. This "non-cylindrical" fit (such as rectangular, D-shaped, polygonal, etc.) automatically completes circumferential positioning at the moment of insertion, ensuring that there is no relative rotation between the positioning movable shaft seat and the positioning fixed shaft seat. The subsequent rotation of the positioning fixed shaft seat can drive the positioning movable shaft seat to rotate synchronously. The rotational torque of the positioning fixed shaft seat can be transmitted to the positioning movable shaft seat and the tightened workpiece with zero lag and high rigidity. While providing a high-speed, high-precision winding foundation, this insertion design allows for quick axial assembly and disassembly.

[0028] The second connecting part is used to establish axial linkage between the pressure shaft and the positioning movable shaft seat when the workpiece is unloaded. The movement of the pressure shaft drives the positioning movable shaft seat to separate from the positioning fixed shaft seat. When the workpiece is wound on the positioning movable shaft seat, the end face of the pressure shaft abuts against the end face of the workpiece, thereby pressing the workpiece. At this time, under the action of the third driving part, the second connecting block is inserted into the connecting hole, and the pressure shaft and the positioning movable shaft seat are connected. After the workpiece winding operation is completed, when the workpiece is unloaded, the second driving part drives multiple positioning arc plates to retract radially (i.e., multiple positioning arc plates move in a direction that approaches each other). The outer diameter of the overall structure formed by the multiple positioning arc plates is smaller than the inner hole of the workpiece's central through hole. The workpiece slides down along the length of the positioning arc plates onto the positioning fixed shaft seat. After this, the pressure shaft drives the first connecting seat to move through the second connecting block, thereby driving the positioning movable shaft seat to move away from the positioning fixed shaft seat, completely pulling the positioning movable shaft seat out of the loosened inner hole of the workpiece, making room for the unloading equipment.

[0029] In the above process, the first connecting part solves the problems of power transmission accuracy and rapid changeover, while the second connecting part solves the problem of automatic avoidance of the positioning module during unloading. The two work together to make the positioning movable shaft a "fixed rotating axis" during winding and a "movable guide extraction axis" during unloading. The two states are automatically switched through a simple mechanical pin and drive, transforming complex, time-sensitive multi-axis collaborative actions (rotation, tightening, pressing, retraction, extraction) into precisely controlled mechanical interlocking actions by two modular connecting parts, greatly simplifying the control system logic.

[0030] In summary, this application includes at least one of the following beneficial technical effects: 1. By reciprocating the fork base, the winding and tap straightening functions are innovatively combined, realizing online and automatic straightening, eliminating the need for independent post-processing, and greatly improving production efficiency and product consistency; 2. The structure of multiple sets of hanging parts and winding grooves can guide and constrain multiple taps in an orderly manner. Combined with a movable wire cutting mechanism, it can achieve neat arrangement and precise synchronous cutting of multiple taps. 3. The wire-setting mechanism integrates the winding post, pressure plate, anti-detachment seat, and anti-detachment clamp, which not only reliably fixes the wire end, but also achieves seamless connection of the winding cycle of the front and rear workpieces through the "pre-stored wire end" mechanism, minimizing the idle time of the equipment.

The pressing shaft 401 can move in a direction close to the positioning shaft 201 to press the workpiece 66 against the positioning shaft 201. 1. A tap wire holder 9 is provided on the pressure shaft 401; a wire cutting mechanism 5 is provided on one side of the tap wire holder 9; the flying fork mechanism 6 includes a flying fork base 601 movably provided in the frame 1, the flying fork base 601 can reciprocate between the positioning shaft 201 and the tap wire holder 9, the flying fork base 601 is provided with a feeding clamp 602 for clamping the workpiece 66, and a winding head 603 for pulling the wire and winding the wire onto the workpiece 66 is rotatably provided on the flying fork base 601.

[0035] Reference Figures 1-8 A positioning drive motor 32 is installed inside the frame 1. The output shaft of the positioning drive motor 32 is connected to the positioning shaft 201 via a pulley. The positioning shaft 201 is rotatably mounted on the frame 1 via bearings. The positioning shaft 201 is vertically positioned. The rotation of the output shaft of the positioning drive motor 32 can drive the positioning shaft 201 to rotate via the pulley. A positioning seat 13 for docking with the central through hole of the workpiece 66 is fixed at the top of the positioning shaft 201. During the loading stage of the workpiece 66, the loading fixture 602 transports the workpiece 66 to the positioning shaft 201. The positioning seat 13 passes through the central through hole of the workpiece 66, thereby completing the initial radial and circumferential positioning of the workpiece 66.

[0036] Reference Figures 1-8 The frame 1 is equipped with a fork drive rail 33, and a fork drive seat 34 is slidably mounted on the fork drive rail 33. The fork drive rail 33 is horizontally mounted. The frame 1 is equipped with a fork drive motor 35, and a fork drive screw 36 is coaxially fixedly connected to the output shaft of the fork drive motor 35. The screw nut of the fork drive screw 36 is fixedly connected to the bottom of the fork drive seat 34. The fork drive screw 36 is parallel to the fork drive rail 33. The rotation of the output shaft of the fork drive motor 35 drives the fork drive screw 36 to rotate. The cooperation between the fork drive rail 33 and the fork drive seat 34 restricts the degree of freedom of rotation of the fork drive seat 34. The fork drive seat 34 slides on the fork drive rail 33. The fork base 601 is mounted on the fork drive seat 34. The positioning shaft 201 is located on the movement trajectory of the fork drive seat 34. The fork base 601 can thus move in a direction away from or close to the positioning shaft 201.

[0037] Reference Figures 1-8The frame 1 is equipped with a drive base plate 37, a fly fork drive rail 33, a fly fork drive motor 35, and a fly fork drive screw 36, all of which are mounted on the drive base plate 37. A base plate screw 38 is rotatably mounted inside the frame 1 and is vertically mounted. A base plate motor 39 is mounted inside the frame 1, and the output shaft of the base plate motor 39 is coaxially and fixedly connected to the base plate screw 38. A base plate drive plate 40 is fixedly connected to the screw nut of the base plate screw 38. Multiple base plate guide rods 41 are provided at the bottom of the drive base plate 37. A base plate guide hole 42 is provided on the frame 1 for the corresponding base plate guide rods 41 to pass through and slide. The end of the base plate guide rod 41 away from the drive base plate 37 is connected to the base plate drive plate 40. The rotation of the output shaft of the substrate motor 39 can drive the substrate lead screw 38 to rotate. With the cooperation of the substrate guide rod 41 and the substrate guide hole 42, the degree of freedom of rotation of the substrate drive plate 40 is restricted. The substrate drive plate 40 can thus move along the length direction of the substrate lead screw 38. At the same time, driven by the substrate guide rod 41, the drive substrate 37 moves synchronously. The drive substrate 37 thereby drives the fly fork drive rail 33 and fly fork base 601 on it to move.

[0038] In the above process, the cooperation of the fly fork drive rail 33, fly fork drive seat 34, fly fork drive motor 35 and fly fork drive screw 36 provides the fly fork base 601 with the freedom to move along the X-axis, so that the fly fork base 601 can move in a direction away from or close to the positioning axis 201; the cooperation of the drive base 37, base plate screw 38, base plate motor 39, base plate guide rod 41 and base plate guide hole 42 provides the fly fork base 601 with the freedom to move along the Z-axis, so that the fly fork base 601 can reciprocate between the positioning axis 201 and the tap hook seat 9.

[0039] Reference Figures 1-8 The fly fork base 601 is equipped with a winding drive motor (not shown in the figure) for driving the winding head 603 to rotate. The rotation of the output shaft of the winding drive motor drives the winding head 603 to rotate, and the rotation of the winding head 603 pulls the wire. The loading clamp 602 includes two loading clamps 6021 disposed opposite to each other on the fork base 601. The two loading clamps 6021 can move in a direction that approaches or moves away from each other to clamp or release the workpiece 66. The fork base 601 is provided with a clamp guide rail 6023. The two loading clamps 6021 are slidably disposed on the clamp guide rail 6023 through clamp guide blocks 6022 respectively. The fork base 601 is provided with a power source for driving the clamp guide blocks 6022 to slide on the clamp guide rail 6023. The sliding of the clamp guide blocks 6022 on the clamp guide rail 6023 can drive the loading clamps 6021 to slide, thereby enabling the two loading clamps 6021 to clamp or release the workpiece 66.

[0040] Reference Figures 1-8The fork base 601 is provided with an abutment seat 15 located between two feeding clamps 6021. The abutment seat 15 can move in the direction of approaching or moving away from the positioning shaft 201. The fork base 601 is also provided with an elastic element for providing a biasing force to the abutment seat 15 in the direction of the positioning shaft 201. The positioning mechanism 2 also includes a positioning wedge 16 movably disposed in the frame 1. The positioning wedge 16 is disposed on the side of the positioning shaft 201 away from the abutment seat 15. The positioning wedge 16 can move in the direction of approaching the positioning shaft 201.

[0041] Reference Figures 1-8 A connecting rod 44 is provided on the fork base 601 facing the positioning shaft 201, and a hole is provided on the abutment 15 for the connecting rod 44 to slide. The elastic element includes a spring wound on the connecting rod 44, one end of the spring is fixed to the fork base 601, and the other end is fixedly connected to the side of the abutment 15 away from the positioning shaft 201. A positioning mounting bracket 45 is provided on the side of the positioning shaft 201 away from the fork base 601, and a positioning cylinder 46 is provided on the positioning mounting bracket 45. The output shaft of the positioning cylinder 46 is connected to the positioning wedge 16, and the operation of the output shaft of the positioning cylinder 46 can drive the positioning wedge 16 to move in a direction away from or close to the positioning shaft 201.

[0042] To improve the accuracy of winding on different working surfaces of workpiece 66, refer to Figures 1-8 A protective plate 47 is provided on each side of the positioning shaft 201. The two protective plates 47 are arranged opposite each other, and the ends of the two protective plates 47 that are close to each other form an opening for the abutment seat 15 and the feeding clamp 6021 to enter and exit. A protective drive rail 48 is provided on the frame 1, and a protective drive seat 49 is slidably arranged on the protective drive rail 48. The protective plate 47 is set on the protective drive seat 49. A protective cylinder 50 is provided on the frame 1. The protective cylinder 50 is located between the flying fork base 601 and the positioning shaft 201. The output shaft of the protective cylinder 50 is horizontally arranged. The output shaft of the protective cylinder 50 is connected to the protective drive seat 49. The movement of the output shaft of the protective cylinder 50 can drive the protective drive seat 49 to slide on the protective drive rail 48. The protective plate 47 can thus move in a direction away from or close to the positioning shaft 201. The opening formed by the two protective plates 47 approaching each other allows one working surface of the workpiece 66 to be exposed. Under this setting, the winding head 603, the feeding clamp 6021 and the abutment seat 15 can more accurately engage with each working surface of the workpiece 66, thereby performing the overall winding of the workpiece 66.

[0043] Reference Figures 1-8The frame 1 contains a pressing frame 7, and a pressing shaft 401 is rotatably mounted on the pressing frame 7 via bearings. The frame 1 also contains a pressing drive 8 for driving the pressing frame 7 to move towards or away from the positioning shaft 201. The frame 1 contains two opposing pressing mounting frames 51. The pressing drive 8 includes two pressing cylinders 801, which are respectively mounted on the two pressing mounting frames 51. The output shafts of the two pressing cylinders 801 are both vertically oriented, and each of the two pressing cylinders 801 has a pressing guide seat 802. The two pressing guide seats 802 are respectively connected to both ends of the pressing frame 7. Each of the two pressing mounting frames 51 has a pressing guide rod 52, which is vertically oriented. Each of the two pressing guide seats 802 has a pressing guide bearing 53, which is slidably connected to the corresponding pressing guide rod 52.

[0044] The operation of the output shaft of the pressing cylinder 801 can drive the pressing guide seat 802 to move up and down. The two pressing guide seats 802 thereby drive the pressing frame 7 to move up and down. The pressing shaft 401 connected to the pressing frame 7 by bearings moves accordingly. During the lifting and lowering of the pressing frame 7, the pressing guide bearing 53 slides on the corresponding pressing guide rod 52, thereby making the movement of the pressing frame 7 more stable and smooth.

[0045] Reference Figures 1-8 The pressure shaft 401 has a receiving cavity 14 for accommodating the positioning seat 13. The shape of the receiving cavity 14 is adapted to the shape of the positioning seat 13. During the loading stage of the workpiece 66, the loading fixture 602 transports the workpiece 66 to the positioning shaft 201. The positioning seat 13 passes through the central through hole of the workpiece 66, thereby completing the initial radial and circumferential positioning of the workpiece 66. The positioning seat 13 extends out after passing through the central through hole of the workpiece 66. Subsequently, the pressure shaft 401 moves towards the positioning shaft 201 to perform a pressing action. During this process, the receiving cavity 14 at the front end of the pressure shaft 401 can just accommodate the extended positioning seat 13, so that the end face of the pressure shaft 401 can directly press against the end face of the workpiece 66 without interference. The positioning seat 13 is completely embedded in the receiving cavity 14. With the cooperation of the positioning seat 13 and the receiving cavity 14, the rotation of the positioning shaft 201 can synchronously drive the workpiece 66 and the pressure shaft 401 to rotate.

[0046] Reference Figures 1-8The tap wire holder 9 includes a fixed base 901 mounted on the pressure shaft 401. Multiple sets of wire-hanging sections are arranged circumferentially on the fixed base 901, the number of which is less than the number of working surfaces of the workpiece 66. Each set of wire-hanging sections includes two spaced-apart wire-hanging plates 902, forming a wire-cutting gap 10 between the two plates. The wire-cutting mechanism 5 is movably mounted within the frame 1, its movement path configured to feed the shear blade 504 into or out of the wire-cutting gap 10. A winding groove 12 is provided on the wire-hanging plate 902. The two wire-hanging plates 902 in each set of wire-hanging sections are arranged opposite each other, and the winding grooves 12 on the two plates 902 are positioned opposite each other, forming a conductor space.

[0047] After workpiece 66 is conveyed onto positioning shaft 201, pressure cylinder 801 drives pressure frame 7 to move as a whole, thereby driving pressure shaft 401 and tap wire holder 9 to be precisely positioned. As pressure shaft 401 presses workpiece 66 onto positioning shaft 201, the fixed seat 901 and multiple circumferentially arranged wire holders on it also reach their working positions. Afterwards, the rotation of positioning shaft 201 causes workpiece 66 and pressure shaft 401 to rotate synchronously, and multiple circumferentially arranged wire holders on workpiece 66... The spaced working surfaces rotate and align sequentially with the winding head 603, which then completes the winding of each working surface in turn. During winding, after completing the winding of one working surface, the winding head 603 guides the taps from that surface to the corresponding set of hanging sections, where they are hung between two spaced hanging plates 902. When the positioning shaft 201 rotates to send the next working surface to the winding position, the winding head 603 can again guide the newly generated taps to the same or the next set of hanging sections. The cutting gap 10 formed between the two hanging plates 902 provides a unified cutting channel for all taps hung in that set. After all winding and tap hanging is completed, the cutting mechanism 5 moves along its preset path, sequentially or simultaneously inserting the cutting blades 504 into the cutting gaps 10 of each hanging section, thus cutting multiple taps gathered in the same gap at once, or sequentially cutting all taps within the gaps.

[0048] Reference Figures 1-8The wire setting mechanism 3 includes a winding post 301 and a pressing plate 302. The winding post 301 is disposed on the pressing shaft 401 and is used to wind the wire end of the conductor. The pressing plate 302 is movably disposed at the end of the winding post 301 away from the pressing shaft 401. The pressing plate 302 can move in the direction close to or away from the pressing shaft 401 to press out the wire end of the conductor. Both the winding post 301 and the pressure plate 302 are located below the fixed base 901. The winding post 301 is slidably mounted on the pressure shaft 401 along its radial direction. The pressure plate 302 is fixed to one end of the pressure shaft 401. A mating hole 55 is provided in the pressure shaft 401 for the winding post 301 to slide. A spring is installed in the mating hole 55 and wound around the winding post 301. One end of the spring is fixed in the mating hole 55, and the other end is fixed to the winding post 301. A wire-fixing seat 56 is provided at the end of the winding post 301 away from the pressure plate 302. The wire-fixing seat 56 is mounted on the pressure frame 7. A positioning cylinder 57 is provided on the positioning base 56. A positioning pressure block 58 is provided on the output shaft of the positioning cylinder 57. The positioning pressure block 58 can move in the direction of approaching or moving away from the winding post 301 under the drive of the positioning cylinder 57. The spring in the mating hole 55 provides pressure to the pressure plate 302 that is always biased towards the pressure shaft 401. The positioning pressure block 58 can abut against the end of the winding post 301 away from the pressure plate 302, and then press the winding post 301. The winding post 301 slides in the mating hole 55, and the pressure plate 302 moves in the direction away from the pressure shaft 401.

[0049] Before winding begins, the guide block 58 presses the winding post 301 into place. One end of the winding post 301 near the pressure plate 302 protrudes slightly through the mating hole 55. A certain distance remains between the pressure plate 302 and the pressure shaft 401. The spring inside the mating hole 55 is under pressure. After this, the wire end is initially wound onto the winding post 301 via the winding head 603. Subsequently, the guide block 58 moves away from the winding post 301, and the end of the winding post 301 away from the pressure plate 302 is no longer pressed. The spring inside the mating hole 55... Under the action of the internal spring, the winding post 301 is reset, and the pressure plate 302 is driven to press against the pressure shaft 401, thereby physically pressing the wire end against the end face of the winding post 301 to prevent it from coming loose when the subsequent winding head 603 pulls the wire to generate huge tension, thus providing a stable starting tension point for winding; when the winding is completed and the tapping process is finished, and it is necessary to release the wire end to remove the workpiece 66 or to proceed to the next cycle, the pressure plate 302 moves in a direction away from the pressure shaft 401, thereby releasing the pressure plate 302 on the wire end.

[0050] Reference Figures 1-8The locating mechanism 3 is provided with an anti-detachment seat 17 on one side. An anti-detachment clamp 18 is movably provided on the anti-detachment seat 17. The anti-detachment clamp 18 can move in the direction of approaching or moving away from the anti-detachment seat 17 to press the end of the wire. After the end of the wire is pressed onto the anti-detachment seat 17 by the anti-detachment clamp 18, it is pulled by the winding head 603 to be wound onto the winding post 301.

[0051] Reference Figures 1-8 The anti-detachment seat 17 is installed on the pressing frame 7. The anti-detachment seat 17 is equipped with an anti-detachment cylinder 59. The output shaft of the anti-detachment cylinder 59 is connected to the anti-detachment clamp 18. The operation of the output shaft of the anti-detachment cylinder 59 can drive the anti-detachment seat 17 to move in a direction close to or away from the anti-detachment seat 17 to press out the wire end of the conductor.

[0052] In this embodiment, to improve the accuracy and convenience of the wire cutting mechanism 5 when docking with the wire cutting gap 10, the wire cutting mechanism 5 is mounted on the pressure frame 7. The wire cutting mechanism 5 includes a wire cutting mounting base 501 mounted on the pressure frame 7, a wire cutting cylinder 502 mounted on the wire cutting mounting base 501, the output shaft of the wire cutting cylinder 502 facing the fixed base 901, a wire cutting movable seat 503 mounted on the output shaft of the wire cutting cylinder 502, two cutting blades 504 rotatably mounted on the wire cutting movable seat 503, and a power source for driving the two cutting blades 504 to rotate in directions that are close to or far from each other. When the two cutting blades 504 are close to each other, they can cut the taps within the wire cutting gap 10.

[0053] It should be noted that the specific mechanical structure of the winding head 603 and the method of performing the winding action (e.g., guiding the wire to wind onto the workpiece 66 by high-speed rotation), as well as the specific structure of the cutting mechanism 5 that drives the cutting blade 504 to perform the opening and closing cutting action (such as cylinder, motor, cam, linkage, etc.), can all be implemented using conventional existing technical solutions in the flying fork winding machine of this technical field. The improvement of this invention focuses on: innovatively combining the reciprocating motion of the winding head 603 with the straightening function of the tap, and precisely coordinating the movement path of the cutting mechanism 5 with the cutting distance 10 of the tap hanging seat 9, so as to realize the full-process automation from winding, straightening to cutting, rather than modifying the basic structure of the winding head or the cutting blade itself.

[0054] The implementation principle of a winding machine with automatic straightening and cutting functions in Embodiment 1 of this application is as follows: After the equipment is started, the flying fork base 601 moves to the loading position, and the loading clamp 6021 clamps the workpiece 66. The flying fork base 601 sends the workpiece 66 to the positioning seat 13 of the positioning shaft 201. The pressing drive 8 drives the pressing frame 7 to descend, and the pressing shaft 401 presses the workpiece 66 onto the positioning shaft 201, and the positioning seat 13 enters the receiving cavity 14. The winding head 603 takes the wire from the anti-detachment seat 17, drives the wire head to move to one side of the winding post 301, and guides the wire head to the outer periphery of the winding post 301 through the wire nozzle. Then the winding post 301 is reset under the action of the spring, and the pressing plate 302 presses the wire head synchronously. The positioning wedge 16 moves forward, and the abutment seat 15 is attached to the other end of the workpiece 66 under the action of the elastic element to form a stable clamp. The positioning shaft 201 drives the workpiece 66 to rotate, and the winding head 603 sequentially completes the winding of each slot, hooking the tap of each slot into the corresponding winding slot 12 of the hanging part. After all winding is completed, the flying fork base 601 reciprocates between the positioning shaft 201 and the tap hanging seat 9, straightening and smoothing each tap through the winding head 603. Subsequently, the shear blade 504 of the wire cutting mechanism 5 extends into each wire cutting gap 10, cutting all the taps at once. Finally, all mechanisms reset, the finished product is removed, and the winding head 603 pre-stores the wire end of the next workpiece 66 in the anti-detachment seat 17, starting the next cycle. The entire process realizes a fully automatic integrated operation of winding, tap straightening, and cutting. Example 2

[0055] The difference between Example 2 and Example 1 is that: (Refer to...) Figure 9 The pressing shaft 401 includes a pressing fixed shaft 19 movably disposed within the frame 1, a pressing movable shaft 20 coaxially slidably connected to the pressing fixed shaft 19, a first driving part 21 disposed on the pressing fixed shaft 19 for driving the pressing movable shaft 20 to move in a direction away from or close to the pressing fixed shaft 19, a tap hanging seat 9 disposed on the pressing fixed shaft 19, and the pressing movable shaft 20 for pressing the workpiece 66 onto the positioning shaft 201.

[0056] Reference Figure 9The pressing fixed shaft 19 and the pressing movable shaft 20 are provided with interconnected cavities. The first drive unit 21 includes a pressing motor 2101 and a pressing screw 2102. The pressing motor 2101 is disposed in the cavity, and the pressing screw 2102 is rotatably disposed in the cavity. The output shaft of the pressing motor 2101 is coaxially and fixedly connected to the pressing screw 2102. The rotation of the pressing motor 2101 can drive the pressing screw 2102 to rotate. A pressing drive seat 2103 is fixed on the screw nut of the pressing screw 2102. The pressing drive seat 2103 is connected to the pressing movable shaft 20. Multiple pressing slides 2104 parallel to the pressing screw 2102 are also provided in the cavity. The multiple pressing slides 2104 pass through the pressing drive seat 2103 through holes. The rotation of the output shaft of the pressure motor 2101 drives the pressure screw 2102 to rotate. With the cooperation of multiple pressure slides 2104, the degree of freedom of rotation of the pressure drive seat 2103 is restricted. The pressure drive seat 2103 moves along the length of the pressure screw 2102, thereby driving the pressure movable shaft 20 to move away from or towards the pressure fixed shaft 19. The receiving cavity 14 for accommodating the positioning seat 13 is opened at the bottom end of the pressure movable shaft 20.

[0057] The implementation principle of the winding machine with automatic straightening and cutting functions in Embodiment 2 of this application is as follows: The pressing shaft 401 adopts a separate pressing fixed shaft 19 and pressing movable shaft 20. During implementation, when changing product specifications or adjusting the tap length, the extension length of the pressing movable shaft 20 is adjusted by the first drive unit 21, thereby changing the fixed distance between the workpiece 66 after pressing and the tap hanging seat 9, and thus setting the reserved length of the tap. During winding, the pressing fixed shaft 19 supports the stable rotation of the hanging seat, while the pressing movable shaft 20 independently provides the pressing force without interference. This ensures the accuracy and stability of winding and hanging while achieving convenient adjustment of the tap length. Example 3

[0058] The difference between Example 3 and Example 1 is that: (Refer to...) Figures 10-12 The positioning shaft 201 includes a positioning fixed shaft seat 22 rotatably disposed within the frame 1. The positioning fixed shaft seat 22 is detachably connected to a positioning movable shaft seat 23 via a first connecting part. Multiple positioning arc plates 24 are slidably disposed on the positioning movable shaft seat 23. The positioning arc plates 24 have stepped surfaces 11 that can abut against the bottom end of the workpiece 66. A second driving part 25 is disposed on the positioning movable shaft seat 23. The second driving part 25 is used to drive the multiple positioning arc plates 24 to move in a direction close to or away from the axis of the positioning movable shaft seat 23. The positioning movable shaft seat 23 is detachably connected to the pressure shaft 401 via a second connecting part.

[0059] Reference Figures 10-12The first connecting part includes a first connecting block 26, which is disposed on the positioning movable shaft seat 23 and is non-cylindrical. The positioning fixed shaft seat 22 has a connecting groove, the shape of which is adapted to the shape of the first connecting block 26 and is used for the insertion of the first connecting block 26. The second connecting part includes a first connecting seat 27 disposed on the positioning movable shaft seat 23 and a second connecting seat 28 disposed on the pressure shaft 401. The first connecting seat 27 has a connecting hole 29, the second connecting seat 28 has a second connecting block 30, and the pressure shaft 401 has a third driving part 31 for driving the second connecting block 30 to be inserted into the connecting hole 29.

[0060] In this embodiment, the first connecting block 26 is cross-shaped. When the workpiece 66 falls onto the positioning and fixing shaft seat 22, the bottom end face of the workpiece 66 is flush with the positioning and fixing shaft seat 22 (i.e., there is no protrusion on the positioning and fixing shaft seat 22), which facilitates the unloading of the workpiece 66.

[0061] Reference Figures 10-12 The second drive unit 25 includes a plurality of electrically controlled first telescopic rods 2501 disposed on the positioning movable shaft seat 23. The first telescopic rods 2501 are arranged radially along the positioning movable shaft seat 23. One end of the first telescopic rod 2501 is fixedly connected to the positioning movable shaft seat 23, and the other end is fixedly connected to the inner side of the corresponding positioning arc plate 24. The multiple positioning arc plates 24 can be driven to move by the telescopic movement of the multiple first telescopic rods 2501.

[0062] In this embodiment, to improve the tightness of the connection between the pressure shaft 401 and the positioning movable shaft seat 23, two second connecting blocks 30 are provided. The pressure shaft 401 has a mounting cavity at its bottom end. The third drive unit 31 includes an electrically controlled second telescopic rod 3101 disposed within the mounting cavity. The second telescopic rod 3101 is vertically arranged, with its fixed end fixedly connected to the pressure shaft 401 and its movable end fixedly connected to the second connecting seat 28. Electrically controlled third telescopic rods (not shown in the figure) are respectively provided on both sides of the mating seat. The third telescopic rods are horizontally arranged, with their fixed ends fixedly connected to the mating seat and their movable ends respectively... It is fixedly connected to two second connecting blocks 30; a cavity is opened in the positioning movable shaft seat 23, and the first connecting seat 27 is set in the cavity. The first connecting seat 27 has a cavity for the second connecting seat 28 to enter and exit (the second connecting seat 28 is driven to enter and exit the cavity by the telescopic movement of the second telescopic rod 3101). Two connecting holes 29 are opened and communicate with the cavity. The two connecting holes 29 are used to allow the corresponding second connecting block 30 to be inserted respectively (the corresponding second connecting block 30 is driven to be inserted into the connecting hole 29 by the telescopic movement of the third telescopic rod).

[0063] Reference Figures 10-12The frame 1 is equipped with a feeding rack 63, and the feeding rack 63 is equipped with an electrically controlled fourth telescopic rod 64. The fixed end of the fourth telescopic rod 64 is fixedly connected to the feeding rack 63, and the movable end of the fourth telescopic rod 64 is equipped with a feeding clamp 65. The telescopic movement direction of the fourth telescopic rod 64 is towards the positioning and fixing shaft seat 22. The telescopic movement of the fourth telescopic rod 64 can drive the feeding clamp 65 to move.

[0064] Reference Figures 10-12 The unloading clamp 65 includes an unloading plate 6501 mounted on the movable end of the fourth telescopic rod 64. A bidirectional lead screw (not shown in the figure) is driven to rotate on the unloading plate 6501 by the unloading motor 6502. Unloading clamps 6503 are respectively mounted on the two lead screw nuts of the bidirectional lead screw. The unloading plate 6501 is provided with a sliding groove slider structure to prevent the unloading clamps 6503 from rotating relative to the bidirectional lead screw. The two unloading clamps 6503 are arranged opposite to each other. Anti-slip arc plates 6504 are provided on the opposite side of the two unloading clamps 6503. The shape of the anti-slip arc plates 6504 is adapted to the shape of the workpiece 66 and is used to clamp the workpiece 66. When the workpiece 66 is unloaded by the unloading clamp 65, the fourth telescopic rod 64 can drive the unloading clamp 65 to reach the unloading position of the workpiece 66 in advance. The two unloading clamps 6503 and their anti-slip arc plates 6504 are far apart from each other to avoid interfering with the unloading process of the workpiece 66. After the workpiece 66 falls to the unloading position, the unloading motor 6502 drives the bidirectional lead screw to rotate. The two lead screw nuts on the bidirectional lead screw drive the two unloading clamps 6503 to move in a direction that approaches each other. The two anti-slip arc plates 6504 contact the two sides of the workpiece 66 to clamp the workpiece 66. After this, the fourth telescopic rod 64 can drive the unloading plate 6501 away from the positioning and fixing shaft seat 22.

[0065] The implementation principle of the winding machine with automatic straightening and cutting functions in Embodiment 3 of this application is as follows: The workpiece 66 is fitted onto the retractable positioning arc plate 24. The second drive unit 25 drives the positioning arc plate 24 to expand radially along the positioning movable shaft seat 23, tightening the workpiece 66 from the inner hole. After winding is completed, the second drive unit 25 drives the positioning arc plate 24 to retract. The workpiece 66 automatically loosens because its inner diameter is larger than the outer diameter of the positioning arc plate 24 after retraction, and slides down along the guide surface of the positioning movable shaft seat 23 to the positioning fixed shaft seat 22 or the unloading station under the action of gravity. At the same time, the pressure shaft 401 is connected to the positioning movable shaft seat 23 through the second connecting part, and drives it to be lifted upward together, completely pulling it out from the loosened workpiece 66, providing unobstructed operating space for the unloading fixture 65, realizing automatic and non-destructive unloading of the workpiece 66 after winding, greatly improving the continuity of production and the degree of automation.

[0066] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
