[0031] See also Figures 1 to 3 The embodiment of the utility model provides a chuck for a stranding machine with automatic clamping, which comprises: a chuck base plate 1, a first pressing block 11 is provided on the upper side of one end of the chuck base plate 1, and a first pressing groove 111 opening upward is provided on the first pressing block 11; a chuck pressing plate 2, a second pressing block 21 is provided on the lower side of one end of the chuck pressing plate 2, and a second pressing groove 211 opening downward is provided on the second pressing block 21, and the chuck pressing plate 2 is rotatably connected to the upper side of the chuck base plate 1; wherein, an electromagnet 12 is provided on the other end of the chuck base plate 1, and the other end of the chuck pressing plate 2 is provided with an electromagnet 12. A magnetic attraction portion 22 is provided at one end. When the electromagnet 12 is energized, the other end of the chuck pressure plate 2 is magnetically attached to the other end of the chuck base plate 1 to separate the first pressure block 11 from the second pressure block 21. A reset elastic member 4 is also provided between the chuck base plate 1 and the chuck pressure plate 2. When the electromagnet 12 is not energized, the reset elastic member 4 provides elastic force to separate the other end of the chuck pressure plate 2 from the other end of the chuck base plate 1 to make the first pressure block 11 fit with the second pressure block 21, and the first pressure groove 111 and the second pressure groove 211 enclose a wire pressing hole 3.
[0032] Optionally, the magnetic attraction portion 22 can be a magnetic member disposed at the other end of the chuck plate 2, and when the electromagnet 12 is energized, the electromagnet 12 and the magnetic member are attracted. Optionally, the magnetic attraction portion 22 can also be a magnetic material possessed by the other end of the chuck plate 2, that is, the other end of the chuck plate 2 is a magnetic material, and when the electromagnet 12 is energized, the electromagnet 12 and the magnetic material are attracted.
[0033] It should be explained that when using the chuck of the automatic wire clamping and twisting machine of the utility model, the operator first places the wire to be twisted between the first pressing groove 111 and the second pressing groove 211. Then, the working state of the electromagnet 12 is controlled by controlling the on and off of the external power supply. When the electromagnet 12 is energized, the magnetic force it generates attracts the magnetic attraction portion 22 on the chuck pressing plate 2, so that the other end of the chuck pressing plate 2 is magnetically attached to the other end of the chuck bottom plate 1. Correspondingly, at this time, the first pressing block 11 is separated from the second pressing block 21, the wire pressing hole 3 is opened, and the wire can be smoothly inserted. When the electromagnet 12 is powered off, the reset elastic member 4 immediately takes effect, providing elastic force to push the other end of the chuck pressing plate 2 away from the other end of the chuck bottom plate 1. Correspondingly, at this time, the first pressing block 11 is tightly attached to the second pressing block 21, and the wire pressing hole 3 is closed to firmly clamp the wire. Optionally, the reset elastic member 4 can be a spring, the upper end of the spring is connected to the chuck plate 2, the lower end is connected to the chuck base plate 1, and when the spring is in the initial state, the first pressing block 11 and the second pressing block 21 are tightly fitted. Preferably, the first pressing block 11, the rotation connection between the chuck plate 2 and the chuck base plate 1, the reset elastic member 4, and the electromagnet 12 are located on the same straight line. Optionally, the first pressing groove 111 is a semicircular groove, the second pressing groove 211 is also a semicircular groove, and the wire pressing hole 3 is a circular hole.
[0034] Furthermore, the chuck of the wire twisting machine also includes a main shaft 5, and the other end of the chuck base plate 1 is provided with a main shaft 5 insertion hole, and the main shaft 5 is inserted into the main shaft 5 insertion hole. The main shaft 5 is used to drive the chuck base plate 1 to rotate. The operator can rotate the main shaft 5 to drive the entire chuck and the clamped wire to rotate together to achieve the twisting of the wire. Optionally, it also includes a driving device, which is used to drive the main shaft 5 to rotate.
[0035] Further, considering the design of the power supply circuit of the electromagnet 12, the present embodiment is provided with a conductor ring on the main shaft 5, the conductor ring is rotatably connected with the main shaft 5, the conductor ring is electrically connected to the electromagnet 12 through the conductor bar, and the conductor ring is also electrically connected to the external power supply. In the present embodiment, the conductor ring is connected to the electromagnet 12 through the conductor bar, and is connected to the external power supply at the same time, forming a complete circuit. When the current flows into the conductor ring through the external power supply, and then is conducted to the electromagnet 12 through the conductor bar, the electromagnet 12 is stimulated by the current to generate a magnetic force, attracting the magnetic suction part 22 on the chuck pressing plate 2, so that the chuck pressing plate 2 and the chuck bottom plate 1 are magnetically attached, and the wire pressing hole 3 is opened, and the wire is smoothly put in. When the current is interrupted, the electromagnet 12 loses its magnetic force, and the chuck pressing plate 2 quickly returns to the original position under the action of the reset elastic member 4, so that the first pressing block 11 and the second pressing block 21 are closely attached, and the wire pressing hole 3 is closed to clamp the wire. At this time, the operator can rotate the main shaft 5 to drive the entire chuck and the clamped wire to rotate together, thereby achieving twisting of the wires. At the same time, since the conductor loop is rotationally connected to the main shaft 5, the conductor loop will not rotate with the main shaft 5, and the circuit remains stable.
[0036] Optionally, the conductor ring is a copper ring, and the conductor bar is a copper bar. The copper ring as the conductor ring can ensure that the current flows smoothly in the conductor ring, reduce energy loss and voltage drop, and improve the efficiency of the circuit. The copper bar as the conductor bar can also ensure the stable transmission of the current, ensuring that the electromagnet 12 is sufficiently excited by the current, thereby generating sufficient magnetic force to attract the magnetic attraction portion 22 on the clamping plate 2.
[0037] Further, the conductor loop includes a first conductor loop 51 and a second conductor loop 52, the first conductor loop 51 is connected to the external positive power line 512, and the second conductor loop 52 is connected to the external negative power line 522; or, the first conductor loop 51 is connected to the external negative power line 522, and the second conductor loop 52 is connected to the external positive power line 512. Specifically, the conductor strip includes a first conductor strip 511 and a second conductor strip 521, the first conductor loop 51 is electrically connected to the electromagnet 12 through the first conductor strip 511, and the second conductor loop 52 is electrically connected to the electromagnet 12 through the second conductor strip 521. In one embodiment, when the current flows out from the positive pole of the external power supply, it enters the first conductor loop 51 through the external positive power line 512, and then enters the first conductor strip 511 through the first conductor loop 51, and then is conducted to one end of the electromagnet 12. At the same time, another part of the current flows out from the negative pole of the external power supply, enters the second conductor ring 52 through the external negative power line 522, and then enters the second conductor strip 521 through the second conductor ring 52, and is transmitted to the other end of the electromagnet 12. Thus, the electromagnet 12 is excited by the complete current loop, generating a magnetic force to attract the magnetic attraction part 22 on the chuck pressure plate 2, thereby realizing the opening of the chuck.
[0038] Furthermore, considering that the main shaft 5 needs to rotate and the electromagnet 12 will rotate during operation, the conductor strips arranged between the conductor ring and the electromagnet 12 need to be considered. In this embodiment, the first conductor strip 511 is embedded in the main shaft 5, and one end contacts the inner side of the first conductor ring 51, and the other end contacts the electromagnet 12; the second conductor strip 521 is embedded in the main shaft 5, and one end contacts the inner side of the second conductor ring 52, and the other end contacts the electromagnet 12. It should be explained that the contact in this embodiment refers to a contact connection. When the main shaft 5 and the electromagnet 12 rotate together, the first conductor ring 51 and the second conductor ring 52 do not rotate, and the first conductor strip 511 and the second conductor strip 521 rotate together with the main shaft 5. However, during the rotation, although the relative position of the first conductor strip 511 and the first conductor ring 51 is constantly changing, and the relative position of the second conductor strip 521 and the second conductor ring 52 is constantly changing, the first conductor strip 511 only rotates around the inner circle of the first conductor ring 51 and is always in contact with the first conductor ring 51; the second conductor strip 521 only rotates around the inner circle of the second conductor ring 52 and is always in contact with the second conductor ring 52, thereby ensuring the stability of the circuit. Optionally, a conductive ring is provided inside the chuck bottom plate 1, and the conductive ring is connected to the electromagnet 12. One end of the first conductor strip 511 contacts the inner ring of the conductive ring, and the other end contacts the inner ring of the first conductor circle 51; one end of the second conductor strip 521 contacts the inner ring of the conductive ring, and the other end contacts the inner ring of the second conductor circle 52, and the inner ring diameter of the conductive ring is the same as the diameter of the circle formed by the rotation trajectory of the first conductor strip 511 and the second conductor strip 521. Preferably, the first conductor strip 511 is completely embedded in the main shaft 5, that is, the middle part of the first conductor strip 511 is not connected to other components outside the main shaft 5, and only the two ends contact the electromagnet 12 and the first conductor circle 51; the second conductor strip 521 is completely embedded in the main shaft 5, that is, the middle part of the second conductor strip 521 is not connected to other components outside the main shaft 5, and only the two ends contact the electromagnet 12 and the second conductor circle 52, thereby further ensuring the stability of the circuit. Preferably, in order to avoid leakage, an insulating coating is provided on the first conductor loop 51, the second conductor loop 52, the first conductor strip 511, and the second conductor strip 521 to prevent workers from accidentally getting an electric shock.
[0039] Optionally, in another embodiment, the first conductor ring 51 is located between the electromagnet 12 and the second conductor ring 52, the first conductor strip 511 is separated from or in contact with the main shaft 5, one end of the first conductor strip 511 is fixedly connected to the first conductor ring 51, and the other end is in contact with the electromagnet 12. When the main shaft 5 rotates, the first conductor strip 511 does not rotate; the second conductor strip 521 is embedded in the main shaft 5, one end is in contact with the second conductor ring 52, and the other end is in contact with the electromagnet 12.
[0040] Furthermore, a switch 6 is provided between the external power supply and the conductor ring, and the switch 6 is used to control whether the circuit between the external power supply and the conductor ring is turned on. Optionally, the switch 6 is a pedal switch 6, and the staff can step on the pedal switch 6 according to the opening and closing requirements of the chuck to control the opening and closing of the chuck.
[0041] Furthermore, a carbon brush 7 is provided on the conductor ring, and the carbon brush 7 is connected to an external power supply. Among them, the carbon brush 7 is a commonly used conductive element with good conductivity and wear resistance. The carbon brush 7 is provided on the conductor ring to ensure the stable flow of current in the conductor ring and reduce the occurrence of electrical faults. At the same time, the contact area between the carbon brush 7 and the conductor ring is large, and the contact pressure is uniform, which helps to extend the service life and improve the reliability of the system.
[0042] Furthermore, a first connecting portion 13 extending upward is provided on the chuck base plate 1, and a second connecting portion 23 extending downward is provided on the chuck pressure plate 2. The first connecting portion 13 and the second connecting portion 23 are rotatably connected via a pin shaft 8, and the chuck base plate 1 and the chuck pressure plate 2 are rotatably connected via the first connecting portion 13 and the second connecting portion 23.
[0043] Compared with the prior art, the automatic wire clamping stranding machine chuck of the utility model realizes the automatic opening and closing of the chuck by adopting the cooperation of the electromagnet and the magnetic attraction part. During the production process, the operator no longer needs to manually adjust the opening and closing state of the chuck, which greatly reduces the labor intensity of the operator and significantly improves the production efficiency.
[0044] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
