When the electrostrictive block no longer abuts against the output rotating shaft of the motor, the connecting sleeve can also be supported by the roller and the driving shaft to ensure the stable posture of the connecting sleeve. The connecting sleeve is combined with the current-variable fluid and the elastic outer layer. Not only can it adapt to transmission parts with different inner diameters through simply increasing or decreasing the current-variable fluid, expanding the applicable range in different fields, but also by using the characteristic that the current-variable fluid instantaneously solidifies under the action of a strong electric field, combined with the characteristic that the elastic outer layer bulges out as a whole in a plum blossom shape under the action of the pressurized current-variable fluid, as long as the inner diameter of the transmission part is also made into a plum blossom shape, through the flexible characteristics of the elastic outer layer and the liquid current-variable fluid, the gaps between the transmission parts with different inner diameters and the connecting sleeve can be filled, so as to achieve stable transmission effects for transmission parts of different sizes, and the replacement and disassembly are extremely convenient and fast.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] To enable those skilled in the art of the present technology to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0046] See Figures 1 to 4, an elastic twisting device, including a twisting bracket. This elastic twisting device includes: a flying fork mechanism 1, a spring-loaded wire releasing mechanism 2, and a wire hanging mechanism 3. Specifically, the flying fork mechanism 1 is detachably arranged on one side of the twisting bracket, used to fix one end of the copper wire and quickly rotate to twist three-strand wires into one strand; the spring-loaded wire releasing mechanism 2 is arranged in parallel with the flying fork mechanism 1, used to cooperate with the flying fork mechanism 1 to release the wire after fixing and twisting the other end of the copper wire; the wire hanging mechanism 3 can move between the spring-loaded wire releasing mechanism 2 and the flying fork mechanism 1 in the X-Y plane. Among them: when the wire hanging mechanism 3 makes one cycle, it transports the three-strand wires to the flying fork mechanism 1 for twisting into one strand of wire. Then, the spring-loaded wire releasing mechanism 2 pushes the twisted wire away from the spring-loaded wire releasing mechanism 2 to prepare for the next time. During the whole process, the spring-loaded wire releasing mechanism 2 cooperates with the flying fork mechanism 1 to elastically release the wire after twisting, effectively ensuring that no large copper wire ears are generated during wire release and improving the withstand voltage performance of the finished product.

[0052] Based on the above embodiments, the flying fork mechanism 1 includes: a flying fork mounting base 11, a third power source 12, a rotating shaft 13, a pressing wheel assembly 14, and a flying fork assembly 15.

In this embodiment, the third power source 12 is a servo motor, and the servo motor is fixedly mounted on the flying fork mounting base 11 by bolts. Of course, in other embodiments, the third power source 12 can also be a rotary cylinder type, an electric cylinder type, or a rotary motion mechanical structure; the rotating shaft 13 is rotatably disposed on the shaft mounting hole 111 through a bearing, and a through wire hole is provided on the rotating shaft 13; the third power source 12 can drive the rotating shaft 13 to rotate through a belt transmission device; the belt transmission device is adjustably mounted on the second elongated hole 112; the pressing wheel assembly 14 is self-adjustably mounted on the third elongated hole 113 and is located directly above the rotating shaft 13 for pressing the belt transmission device to prevent tooth skipping; the flying fork assembly 15 is detachably mounted on the other end of the rotating shaft 13 for twisting three strands of wire into one strand.

[0055] In summary, through the setting of the elastic wire releasing mechanism, it can effectively ensure that no large copper wire ears are generated during wire release, and effectively ensure the withstand voltage performance of the finished product.

[0056] See Figures 5 to 8As shown, optionally, since each structural member has a large mass, if a servo motor is used for the third power source 12 and the connecting transmission device 32, the servo motor needs to have a large torque. Since the servo motor is mechanically complex, there are more potential failure points and it is expensive, and torque is not its forte. Therefore, a brushed DC motor or other ordinary motors with stable speed and large torque can be selected here, which can save costs and reduce operation and debugging requirements. However, even if an ordinary motor has a stable speed, it is difficult to meet the accuracy requirements of the actions of this application. Therefore, a connecting sleeve 4 is sleeved outside the motor output rotating shaft 6 to achieve the transition between the motor output rotating shaft 6 and the transmission member, and precise power and stroke transmission are obtained through the connecting sleeve 4, achieving a suitable balance among simple structure, powerful torque, and precise transmission.

[0057] The connecting sleeve 4 includes a star-shaped frame body 41, and partition plates 42 are arranged between adjacent star-shaped frame bodies 41; electrostrictive blocks 43 are fixed between two adjacent star-shaped frame bodies 41 below the partition plates 42; the electrostrictive blocks 43 extend towards the motor output rotating shaft 6 side and press against the motor output rotating shaft 6 in the energized state to transmit the rotational torque of the motor output rotating shaft 6; a friction layer is coated on the outer circumferential surface of the motor output rotating shaft 6 and / or the bottom surface of the electrostrictive block 43 to increase the friction force, and rollers 44 are arranged at the bottom of the star-shaped frame body 41; the rollers 44 abut against and can roll around the outer circumferential surface of the motor output rotating shaft 6; a cylindrical elastic outer layer 45 is fixedly arranged at the outer end of the star-shaped frame body 41; the elastic outer layer 45 and the star-shaped frame body 41 and the partition plates 42 enclose a plurality of sealed cavities 46; a liquid pipe is connected to the sealed cavities 46; an electrorheological fluid 47 is filled into the sealed cavities 46 through the liquid pipe; electrodes 48 are oppositely arranged in the sealed cavities 46; a strong electric field is applied to the electrorheological fluid 47 in the sealed cavities 46 through the electrodes 48 to instantaneously solidify the electrorheological fluid 47.

[0058] Based on the above embodiment, the rollers 44 are arranged on a slider 49, and a chute 50 is formed at the bottom of the star-shaped frame body 41 corresponding to the slider 49; the slider 49 is slidably inserted into the chute 50; a spring 51 is fixed at the bottom of the chute 50; the spring 51 provides a pre-thrust force for the slider 49.

[0059] Based on the above embodiment, an electrostrictive ring 52 is arranged at one end of the connecting sleeve 4 close to the motor; the electrostrictive ring 52 extends towards the motor side and presses against a fixed friction surface to brake in the energized state.

[0060] First, the connecting sleeve 4 is sleeved on the output rotating shaft 6 of the motor. Then, after the corresponding transmission part is sleeved on the connecting sleeve 4, an external liquid pump pumps the electrorheological fluid 47 into the sealed cavity 46 through a liquid pipe, causing the elastic outer layer 45 to bulge outwards into a plum blossom shape, outwardly supporting the transmission part from the inside to the outside. Then, a strong electric field is applied to the electrorheological fluid 47 through the electrode 48, and the electrorheological fluid 47 instantaneously transforms into a solid state, thus ensuring the fixed insertion and matching of the connecting sleeve 4 with transmission parts of various models. At the same time, the electrostrictive block 43 is energized and extends towards one side of the output rotating shaft 6 of the motor, pressing against the outer circumferential surface of the output rotating shaft 6 of the motor. On the one hand, it can adapt to output rotating shafts 6 of different sizes of the motor, and on the other hand, it can ensure the axial center coincidence of the connecting sleeve 4 and the output rotating shaft 6 of the motor, ensure dynamic balance, and can also stably transmit the rotational torque of the output rotating shaft 6 of the motor. When the winding is completed, the electrostrictive block 43 is powered off and retracts, and the electrostrictive block 43 no longer abuts against the output rotating shaft 6 of the motor. The power of the output rotating shaft 6 of the motor is no longer transmitted to the connecting sleeve 4. The connecting sleeve 4 generates support with the output rotating shaft 6 of the motor through the roller 44. At the same time, the electrostrictive ring 52 is energized, and the electrostrictive ring 52 extends towards the friction surface side and presses the fixedly arranged friction surface, realizing braking through friction, similar to an automotive brake pad, thus enabling rapid braking of the connecting sleeve 4, and further enabling rapid braking of the transmission part. When it is necessary to replace or disassemble the transmission part, only the electric field of the electrorheological fluid 47 needs to be disconnected, and a certain amount of the electrorheological fluid is pumped out to easily remove the transmission part.

[0061] An annular magnetic block ring 7 is also fixedly arranged on the friction surface; the annular magnetic block ring 7 includes multiple magnetic blocks arranged alternately; the positive and negative poles of adjacent magnetic blocks are opposite; one end of the connecting sleeve 4 corresponding to the annular magnetic block ring 7 is also provided with a magnetoelectric sensor, and a Hall sensor can be used. During the rotation of the connecting sleeve 4, the magnetoelectric sensor senses the magnetic field change of the annular magnetic block ring 7 and converts it into an electrical signal to accurately record the number of rotation turns and the angle of the connecting sleeve 4, and transmits the information to the controller of the device. The controller controls the power on and off of the electrostrictive block 43 and the electrostrictive ring 52 according to the set action parameters, and controls the forward and reverse rotation of the motor.

[0062] The above are only embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
