Description

Technical Field

[0001] The present application relates to the technical field of flexible shaft processing equipment, and in particular to a flexible shaft wire winding machine. Background Art

[0002] A flexible shaft is a shaft with very little rigidity, elasticity and free bending transmission, which is used to connect two shafts that are not on the same axis, not in the same direction or have relative movement, so as to transmit rotational motion and torque. The flexible shaft can flexibly transmit rotational motion and torque to any position.

[0003] The flexible shaft includes a core wire and a metal wire. When processing the flexible shaft, it is necessary to evenly wind the metal wire around the core wire. After winding, the metal wire is in a spiral shape, and a certain pitch is formed between adjacent metal wires. Then, the metal wire is welded to the core wire through a melting process to obtain the flexible shaft.

[0004] The existing flexible shafts are formed by a wire winding machine. During the processing process, the metal wire cannot be stably and evenly wound around the core wire, resulting in uneven pitch sizes of the metal wires on the flexible shaft, which in turn affects the transmission accuracy of the flexible shaft.

[0005] Therefore, a flexible shaft wire winding machine is needed to ensure the uniformity of the pitch between the metal wires on the flexible shaft and to ensure the flexibility and transmission accuracy of the flexible shaft. Summary of the Invention

[0006] In order to supply the core wire and the metal wire at a uniform speed and wind the metal wire around the core wire at a uniform speed, the present application provides a flexible shaft wire winding machine.

[0007] A flexible shaft wire winding machine provided by the present application adopts the following technical solutions:

[0008] A flexible shaft wire winding machine includes an equipment body. An unwinding mechanism for uniformly supplying the core wire, a winding component that cooperates with the unwinding mechanism to uniformly convey the core wire and keep the core wire taut, and a winding mechanism for uniformly supplying the metal wire and uniformly winding the metal wire around the core wire are installed on the equipment body. The winding mechanism is arranged between the unwinding mechanism and the winding component. The winding mechanism includes a winding component for uniformly winding the metal wire around the core wire, a wire supply component for uniformly supplying the metal wire to the winding component. The winding component includes a turntable for winding the metal wire around the core wire, a guide wheel group for adjusting the direction of the metal wire output by the wire supply component, and a first driving member for driving the turntable to rotate uniformly. The guide wheel group is rotatably installed on the turntable. The wire supply component includes a wire supply disk that cooperates with the turntable to keep the metal wire taut, and the turntable drives the wire supply disk to rotate uniformly.

[0009] By adopting the above technical solution, the wire pay-off mechanism cooperates with the wire take-up assembly, enabling the core wire to be conveyed at a constant speed and remain in a tensioned state during the conveying process, ensuring the uniform supply of the core wire; in the winding assembly, the first driving member drives the turntable to rotate at a constant speed, causing the metal wire to be wound around the core wire at a constant speed. The guide wheel set on the turntable changes the running direction and winding angle of the metal wire. The wire supply reel in the wire supply assembly is driven by the turntable to achieve the uniform supply of the metal wire. The cooperation between the wire supply reel and the turntable ensures the tension of the metal wire during the winding process, preventing the metal wire from loosening and resulting in uneven winding. Compared with the prior art, both the core wire and the metal wire can be supplied at a constant speed and remain in a tensioned state during the supply process. The winding mechanism winds the metal wire around the core wire at a constant speed, thereby realizing the uniform winding of the metal wire around the core wire, and the pitch of the metal wire on the formed flexible shaft remains uniform.

[0010] Optionally, the guide wheel set includes a first guide wheel, a second guide wheel, and a third guide wheel arranged in sequence along the conveying direction of the metal wire. The metal wire output by the third guide wheel is perpendicular to the axis of the core wire. A first mounting plate for mounting the first guide wheel is provided between the wire supply reel and the turntable. The second guide wheel and the third guide wheel are sequentially arranged on the end face of the turntable along the radial direction of the turntable.

[0011] By adopting the above technical solution, the metal wire output from the wire supply reel is sequentially guided by the first guide wheel, the second guide wheel, and the third guide wheel. The first guide wheel and the second guide wheel are arranged along the radial direction of the turntable. The third guide wheel is mounted on the first mounting plate located between the wire supply reel and the turntable. The running direction of the metal wire changes during the conveying process, and the metal wire output from the third guide wheel is perpendicular to the core wire along the axis of the core wire, ensuring the accurate winding angle of the metal wire around the core wire and improving the winding quality of the metal wire.

[0012] Optionally, the wire pay-off mechanism includes a wire pay-off assembly for releasing the core wire at a constant speed. The wire pay-off assembly includes a wire pay-off reel and a second driving member for driving the wire pay-off reel to rotate at a constant speed. The wire pay-off reel is rotatably mounted on the equipment body, and the second driving member is fixedly mounted at one end of the wire pay-off reel.

[0013] By adopting the above technical solution, the second driving member drives the wire pay-off reel to rotate at a constant speed, enabling the core wire to be released at a constant speed and ensuring the stable tension of the core wire during the wire winding process.

[0014] Optionally, the wire pay-off mechanism further includes a detection assembly for detecting the tension degree of the core wire and controlling the rotation speed of the wire pay-off reel. The detection assembly includes a lifting wheel for receiving the core wire output from the wire pay-off reel and lifting vertically, a sensor for sensing the height position of the lifting wheel, and a controller for receiving the sensing signal and issuing an instruction to control the rotation speed of the second driving member.

[0015] By adopting the above technical solution, the tension degree of the core wire affects the height change of the lifting wheel. After the inductor senses the height position of the lifting wheel, it transmits a signal to the controller, and the controller issues an instruction according to the signal to adjust the rotation speed of the second driving member, thereby achieving precise control of the self-rotation speed of the wire pay-off reel and ensuring that the tension degree of the core wire can be monitored and adjusted in real time.

[0016] Optionally, the wire pay-off mechanism further includes a pressing component for pressing the core wire output by the lifting wheel. The pressing component includes an incoming wire guide wheel for winding the core wire and an incoming wire pressing wheel for pressing the core wire on the incoming wire guide wheel. The incoming wire guide wheel and the incoming wire pressing wheel are rotatably installed on the equipment body.

[0017] By adopting the above technical solution, the core wire is wound on the incoming wire guide wheel, and the incoming wire pressing wheel presses the core wire on the incoming wire guide wheel. The incoming wire guide wheel and the incoming wire pressing wheel cooperate to effectively prevent the core wire from becoming loose or shifting during the conveying process, ensuring that the core wire always maintains a stable tension state during the conveying process.

[0018] Optionally, a second mounting plate rotatably connected to the incoming wire pressing wheel is rotatably installed on the equipment body, and a first elastic member for pressing the incoming wire pressing wheel against the core wire is fixedly installed on the second mounting plate.

[0019] By adopting the above technical solution, the first elastic member pulls the second mounting plate downward, so that the incoming wire pressing wheel always remains in contact with the core wire, avoiding the phenomenon of loosening or shifting of the core wire during the wire supply process, and improving the stability of the core wire conveying process.

[0020] Optionally, the wire take-up assembly includes a take-up wire guide wheel for winding the flexible shaft output by the wire supply reel, a take-up wire pressing wheel for pressing the flexible shaft on the take-up wire guide wheel, and a third driving member for driving the take-up wire guide wheel to rotate uniformly. The take-up wire guide wheel and the take-up wire pressing wheel are rotatably installed on the equipment body, and the third driving member is fixedly installed at one end of the take-up wire guide wheel.

[0021] By adopting the above technical solution, the take-up wire guide wheel and the take-up wire pressing wheel cooperate to ensure that the flexible shaft does not become loose during the wire take-up process. The third driving member drives the take-up wire guide wheel to rotate uniformly, making the wire take-up process of the flexible shaft stable and continuous.

[0022] Optionally, a third mounting plate rotatably connected to the take-up wire pressing wheel is rotatably installed on the equipment body, and a second elastic member for pressing the take-up wire pressing wheel against the flexible shaft is fixedly installed on the third mounting plate.

[0023] By adopting the above technical solution, the second elastic member presses the take-up wire pressing wheel against the flexible shaft, thereby ensuring that the flexible shaft always maintains an appropriate tension force during the wire take-up process, avoiding problems such as slack or uneven winding of the flexible shaft caused by insufficient tension, and improving the stability and reliability of the flexible shaft winding.

[0024] Optionally, a welding assembly for welding the metal wire and the core wire into one body is further installed on the device body. The welding assembly includes a heater for heating the metal wire and the core wire, an oil stain purifier for filtering oil stains, and a purification box for extracting the filtered oil fume. The oil stain purifier is arranged between the heater and the purification box, and the heater, the oil stain purifier, and the purification box are fixedly installed on the device body.

[0025] By adopting the above technical solution, the heater heats the metal wire and the core wire, and can firmly weld the metal wire and the core wire into one body, improving the overall strength and stability of the flexible shaft. The oil stain purifier filters the oil stains generated during the welding process, and the purification box extracts the filtered oil fume, reducing the environmental pollution caused by the operation of the wire winding machine.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. Both the core wire and the metal wire can maintain a uniform wire supply speed and be in a tensioned state during the wire supply process. The wire winding mechanism enables the metal wire to be evenly wound around the core wire, thereby realizing the uniform winding of the metal wire around the core wire, and the pitch of the metal wire on the formed flexible shaft remains uniform;

[0028] 2. The guide wheel group in the wire winding mechanism can accurately adjust the direction of the metal wire, and combined with the uniform rotation of the turntable, it ensures that the metal wire is wound around the core wire at a uniform speed, improving the winding efficiency and accuracy;

[0029] 3. The detection component in the wire pay-off mechanism monitors the tension degree of the core wire in real time and adjusts the wire pay-off speed of the core wire through feedback control, ensuring the stability of the core wire release process. BRIEF DESCRIPTION OF THE DRAWINGS

Through the adjustment of the guide wheel group 10, the running direction of the metal wire output from the wire supply reel 8 is adjusted to be perpendicular to the axis of the core wire. The turntable 9 rotates evenly to drive the adjusted metal wire to be evenly wound around the core wire. As the metal wire is wound around the core wire, the turntable 9 rotates to drive the wire supply reel 8 to rotate, so that the metal wire can be evenly supplied to the turntable 9. The wire supply reel 8 and the turntable 9 respectively tighten both ends of the metal wire, so that the metal wire remains in a tensioned state during the wire supply process. The metal wire is wound around the core wire to form a flexible shaft. The flexible shaft is conveyed to the wire take-up assembly 5.
