Description

Technical Field

[0001] The present invention relates to the technical field of winding rods, and particularly to a winding device with a telescopic winding rod. Background Art

[0002] A winding machine is usually used to wind copper wires on products. Generally, components for realizing the winding function include a winding head for winding and a flying fork that cooperates with the winding head. When the winding head is in the winding working state, the end face at the front end of the winding head is located in front of the end face at the front end of the flying fork, so as to facilitate the winding head to wind the wire. When the winding head is in the hanging wire working state, the end face at the front end of the flying fork is located in front of the end face at the front end of the winding head, so as to facilitate the winding head to cooperate with the flying fork to hang the wire. In the prior art, in order to implement the above technical solution, generally the method of fixing the flying fork and moving the winding head is adopted, that is, when the winding head needs to hang the wire, the winding head is moved backward so that the end face at the front end of the winding head is located behind the end face at the front end of the flying fork. After the wire hanging is completed, it is moved back to its original position so that the end face at the front end of the winding head is located in front of the end face at the front end of the flying fork. Since the volume of the winding head is much larger than that of the flying fork, a relatively large moving space needs to be reserved when installing the winding head, resulting in an increase in the volume of the winding machine, and thus an increase in the assembly and use costs of the winding machine. Therefore, improvement is needed. Summary of the Invention

[0003] The main object of the present invention is to propose a winding device with a telescopic winding rod, aiming to provide a winding device with a winding rod that can move back and forth.

[0004] To achieve the above object, the present invention proposes a winding device with a telescopic winding rod, which includes a winding assembly and a flying fork assembly. A flying fork connecting member is provided at the winding assembly, and the flying fork assembly is connected to the winding assembly through the flying fork connecting member. The flying fork assembly includes a flying fork arm and a flying fork driving module. The flying fork driving module is in transmission connection with the flying fork arm and drives the flying fork arm to move back and forth in the horizontal direction.

[0005] Specifically, the flying fork connecting member includes a flying fork seat. The flying fork driving module includes a flying fork telescopic shaft and a flying fork power member. The rear end of the flying fork arm is connected to the flying fork telescopic shaft, and the flying fork power member is in transmission connection with the flying fork telescopic shaft and drives the flying fork telescopic shaft to extend or contract.

[0006] Specifically, an installation hole is provided at the flying fork seat. A flying fork limit seat that cooperates with the flying fork telescopic shaft is provided in the installation hole. The flying fork telescopic shaft passes through the flying fork limit seat and is connected to the flying fork arm. A limit groove is provided on the outer surface of the flying fork telescopic shaft, and a limit waist-shaped hole is provided at the flying fork limit seat. A flying fork limit pin corresponding to the limit groove is provided at the limit waist-shaped hole. A limit cavity is provided inside the flying fork telescopic shaft, and a flying fork tensioning pin is provided in the limit cavity. The flying fork tensioning pin cooperates with the flying fork limit pin to lock the flying fork telescopic shaft and the flying fork limit seat through the limit waist-shaped hole.

[0007] Specifically, the flying fork tension pin includes an integrally formed locking portion and a transmission portion. The locking portion is located at the front end of the transmission portion. The locking portion is located within the limiting cavity. An unlocking hole is provided at the rear end of the flying fork telescopic shaft, and the unlocking hole communicates with the limiting cavity. The transmission portion extends outside the flying fork limiting cavity through the unlocking hole. The flying fork power member is in transmission connection with the transmission portion. The cross-sectional area of the locking portion is larger than the cross-sectional area of the transmission portion.

[0008] Specifically, a return spring is provided within the limiting cavity. One end of the return spring abuts against the inner wall of the front end of the limiting cavity, and the other end of the return spring abuts against the front end of the locking portion.

[0009] Specifically, the flying fork connecting member further includes a return tension spring. A first tension spring fixing hole is provided at the flying fork limiting seat, and a second tension spring fixing hole is provided at the front end of the flying fork telescopic shaft. Both ends of the return tension spring are respectively fixed to the first tension spring fixing hole and the second tension spring fixing hole by fixing screws.

[0010] Specifically, the flying fork power member includes a flying fork pushing cylinder. The piston rod end of the flying fork pushing cylinder is arranged towards the direction of the flying fork telescopic shaft. A flying fork push plate is provided at the piston rod end of the flying fork pushing cylinder. A flying fork push shaft is provided on the side of the flying fork push plate facing the flying fork telescopic shaft, and the flying fork push shaft is used to push the flying fork telescopic shaft and the flying fork tension pin.

[0011] Specifically, a guide wheel and a wire nozzle are provided at the front end of the flying fork arm. A wire protecting column is provided at the guide wheel, and a guide hole is provided at the wire nozzle. The external wire to be wound sequentially passes through the guide wheel and enters the guide hole of the wire nozzle.

[0012] Specifically, a wire passing hole is provided in the flying fork arm. The guide wheel is arranged within the wire passing hole, and the wire nozzle is obliquely arranged at the front end of the flying fork arm towards the winding assembly direction.

[0013] Specifically, the winding assembly includes a winding head and a winding main shaft. The winding main shaft is in transmission connection with the winding head, and the flying fork arm is arranged above the winding head.

[0014] The technical solution of the present invention realizes the driving of the flying fork arm through the flying fork driving module. By moving the flying fork arm forward, the end face at the front end of the flying fork arm is moved to the front side of the end face at the front end of the winding assembly, so as to facilitate hanging the wire on the winding assembly. By moving the flying fork arm backward, the end face at the front end of the flying fork arm is moved to the rear side of the end face at the front end of the winding assembly, so as to facilitate the winding work of the winding assembly. Furthermore, it effectively reduces the volume and floor area of the winding machine, and reduces the wire hanging difficulty and wire hanging cost of the winding machine.

[0025] As Figures 1 to 6 shown, a winding device with a telescopic winding rod includes a winding assembly 10 and a flying fork assembly 20. A flying fork connecting piece is provided at the winding assembly 10. The flying fork assembly 20 is connected to the winding assembly 10 through the flying fork connecting piece. The flying fork assembly 20 includes a flying fork arm 21 and a flying fork driving module. The flying fork driving module is in transmission connection with the flying fork arm 21 and drives the flying fork arm 21 to move back and forth in the horizontal direction. When the winding assembly 10 is in the winding state, the flying fork arm 21 supplies wire to the winding assembly 10. In order to supply wire to the winding assembly 10 better, the end face of the front end of the flying fork arm 21 is located behind the end face of the front end of the winding assembly 10. In order to better meet the winding requirements between different products, it is necessary to hang the wire on the winding assembly 10. When the winding assembly 10 is in the wire-hanging state, the flying fork driving module drives the flying fork arm 21, so that the end face of the front end of the flying fork arm 21 is located in front of the end face of the front end of the winding assembly 10, thereby facilitating the flying fork arm 21 to provide a wire source for the winding assembly 10, facilitating the winding assembly 10 to hang the wire, and after the winding assembly 10 completes the wire hanging, driving the flying fork arm 21 to reset through the flying fork driving module, so that the end face of the front end of the flying fork arm 21 is reset behind the end face of the front end of the winding assembly 10 again, so as to facilitate the flying fork arm 21 to supply wire to the winding assembly 10; in this embodiment, by adopting the method of driving the flying fork arm 21 to extend or shorten through the flying fork driving module, the rapid wire hanging of the winding assembly 10 is realized, greatly reducing the wire-hanging difficulty of the winding assembly 10. At the same time, driving the winding assembly 10 to hang the wire is avoided, greatly reducing the overall volume of the winding machine, reducing the floor area of the winding machine, and reducing the use cost of the winding machine.

[0026] The flying fork connecting piece includes a flying fork seat 30. The flying fork driving module includes a flying fork telescopic shaft 22 and a flying fork power component. The rear end of the flying fork arm 21 is connected to the flying fork telescopic shaft 22. The flying fork power component is in transmission connection with the flying fork telescopic shaft 22 and drives the flying fork telescopic shaft 22 to extend or contract. An installation hole is provided at the flying fork seat 30. A flying fork limit seat 23 that cooperates with the flying fork telescopic shaft 22 is provided in the installation hole. The flying fork telescopic shaft 22 passes through the flying fork limit seat 23 and is connected to the flying fork arm 21. A limit groove 221 is provided on the outer surface of the flying fork telescopic shaft 22. A limit waist-shaped hole 231 is provided at the flying fork limit seat 23. A flying fork limit pin 24 corresponding to the limit groove 221 is provided at the limit waist-shaped hole 231. A limit cavity 222 is provided inside the flying fork telescopic shaft 22. A flying fork tensioning pin 25 is provided in the limit cavity 222. The flying fork tensioning pin 25 cooperates with the flying fork limit pin 24 to lock the flying fork telescopic shaft 22 and the flying fork limit seat 23 through the limit waist-shaped hole 231. The flying fork tensioning pin 25 includes an integrally formed locking part and a transmission part. The locking part is located at the front end of the transmission part. The locking part is located inside the limit cavity 222. An unlocking hole 223 is provided at the rear end of the flying fork telescopic shaft 22. The unlocking hole 223 communicates with the limit cavity 222. The transmission part extends outside the flying fork limit cavity 222 through the unlocking hole 223. The flying fork power component is in transmission connection with the transmission part. The cross-sectional area of the locking part is larger than the cross-sectional area of the transmission part. A return spring 26 is provided in the limit cavity 222. One end of the return spring 26 abuts against the inner wall of the front end of the limit cavity 222, and the other end of the return spring 26 abuts against the front end of the locking part. The flying fork connecting piece further includes a return tension spring 27. A first tension spring fixing hole is provided at the flying fork limit seat 23. A second tension spring fixing hole 224 is provided at the front end of the flying fork telescopic shaft 22. Both ends of the return tension spring 27 are respectively fixed to the first tension spring fixing hole and the second tension spring fixing hole 224 by fixing screws.The flying fork arm 21 is connected to the winding component 10 through the flying fork seat 30. A flying fork telescopic shaft 22 that can move back and forth is provided at the flying fork seat 30. The rear end of the flying fork arm 21 is connected to the front end of the flying fork telescopic shaft 22. The flying fork power component is drivingly connected to the rear end of the flying fork telescopic shaft 22. By pushing the flying fork telescopic shaft 22 with the flying fork power component, the flying fork telescopic shaft 22 moves forward, thereby driving the flying fork arm 21 to move forward and finally making the end face of the front end of the flying fork arm 21 located on the front side of the end face of the front end of the winding component 10; when the flying fork arm 21 needs to move forward, when the flying fork power component pushes the flying fork telescopic shaft 22, the flying fork power component first contacts the transmission part of the flying fork tensioning pin 25 and pushes the flying fork tensioning pin 25, causing the flying fork tensioning pin 25 to move forward in the limiting cavity 222. As the flying fork tensioning pin 25 moves forward, the gap between the locking part and the flying fork limiting pin 24 increases, enabling the unlocking between the flying fork telescopic shaft 22 and the flying fork limiting seat 23. At the same time, as the flying fork tensioning pin 25 moves forward, the return spring 26 will be compressed to store energy. After the transmission part enters the limiting cavity 222 through the unlocking hole 223 after the flying fork tensioning pin 25 moves forward a certain position, at this time the flying fork power component contacts the flying fork telescopic shaft 22. Since the flying fork telescopic shaft 22 has been unlocked from the flying fork limiting seat 23, the flying fork telescopic shaft 22 can be pushed. When the flying fork telescopic shaft 22 moves forward, the return tension spring 27 will be stored with energy, and then the flying fork arm 21 is driven to move forward by the flying fork telescopic shaft 22; when the flying fork arm 21 needs to move backward, the flying fork power component automatically resets. At this time, the return tension spring 27 provided between the flying fork limiting seat 23 and the flying fork telescopic shaft 22 will generate a pulling force on the flying fork telescopic shaft 22, causing the flying fork telescopic shaft 22 to move toward the flying fork limiting seat 23 and finally return to its original position. At the same time, the return spring 26 will also generate a pushing force on the flying fork tensioning pin 25, causing the flying fork tensioning pin 25 to move backward and pushing the transmission part along the unlocking hole 223 out of the limiting cavity 222. At the same time, since the backward movement of the locking part will squeeze the flying fork limiting pin 24, causing the flying fork limiting pin 24 to slightly lift upward and cooperate with the limiting waist-shaped hole 231 provided at the flying fork limiting seat 23 to limit the flying fork telescopic shaft 22, thereby making the flying fork telescopic shaft 22 fixedly connected to the flying fork limiting seat 23, so as to fix the flying fork arm 21, and then making the flying fork arm 21 stably follow the winding component 10 to move synchronously.

[0027] The flying fork power part includes a flying fork pushing cylinder 28, the piston rod end of the flying fork pushing cylinder 28 is arranged toward the flying fork telescopic shaft 22, a flying fork pushing plate 281 is arranged at the piston rod end of the flying fork pushing cylinder 28, and a flying fork pushing shaft 29 is arranged on the side of the flying fork pushing plate 281 facing the flying fork telescopic shaft 22, and the flying fork pushing shaft 29 is used to push the flying fork telescopic shaft 22 and the flying fork tensioning pin 25. In this embodiment, the flying fork pushing plate 281 is controlled by the piston rod of the flying fork pushing cylinder 28, and then the flying fork pushing shaft 29 is driven to push the flying fork telescopic shaft 22, and in addition, the radius of the flying fork pushing shaft 29 is greater than the radius of the transmission part and smaller than the radius of the flying fork telescopic shaft 22.
