[0041] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.
[0042] like Figures 1 to 9As shown, this embodiment provides an all-in-one torque expansion device, comprising a torque expansion mechanism. The torque expansion mechanism includes at least one torque expansion assembly 1. Each torque expansion assembly 1 includes a torque expansion disk and multiple torque expansion members 13. The torque expansion disk is capable of driving the multiple torque expansion members 13 to move synchronously along the radial direction of the stator and rotate about the axial direction of the stator. The torque expansion member 13 includes a main body 131, which is provided with a wire insertion slot toward the first end of the stator. The stator wire can be inserted into the wire insertion slot. When the multiple main bodies 131 move synchronously along the radial direction of the stator, the stator wire can be expanded. When the multiple main bodies 131 rotate synchronously about the axial direction of the stator, the stator wire can be twisted. The all-in-one torque expansion device provided in this embodiment can both expand and twist the stator wire. Compared with separately providing expansion and twisting mechanisms, the device structure of this all-in-one torque expansion device is simpler. Moreover, the wire only needs to be fixed once for expansion and twisting, making operation more convenient.
[0043] Specifically, the torsion expansion disk includes a coaxially arranged drive disk 12 and a limit disk 11, a spiral groove 121 is provided on the drive disk 12, and a plurality of slide grooves 111 are provided on the limit disk 11. The plurality of slide grooves 111 are arranged at intervals along the circumference of the stator and each slide groove 111 extends radially along the stator. The torque expander 13 also includes a follower portion 132. The main body 131 is located within the chute 111. The follower portion 132 is provided on the main body 131 and is located within the spiral groove 121. The spiral groove 121 is different from the circular groove. The radial distances of each position within the spiral groove 121 from the center of the drive disk 12 are different. Therefore, when the drive disk 12 rotates relative to the limit disk 11, the groove wall of the spiral groove 121 will press against the follower portion 132 located within the spiral groove 121, forcing the follower portion 132 to move. The main body 131 connected to the follower portion 132 is located within the chute 111 and is limited by the extension direction of the chute 111. Therefore, the main body 131 can only move in the radial direction of the stator. In specific implementation, the drive disk 12 can first be rotated in the forward direction relative to the limit disk 11, so that the multiple main bodies 131 move in the radial direction of the stator toward the side closer to the stator, so that the stator wire can be inserted into the wire insertion slot at the first end. Once the wires are fully inserted, the drive disk 12 can be rotated in the opposite direction relative to the limit disk 11, causing the multiple body portions 131 to move radially away from the stator to expand the wires. Because the body portions 131 are located within the chute 111, when the limit disk 11 and drive disk 12 rotate synchronously, the torque expander 13 will also rotate synchronously with the limit disk 11 and drive disk 12 around the axial direction of the stator, thereby twisting the wires inserted into the wire insertion slot.
[0044] like Figure 4As shown, in this embodiment, the expansion and torsion assembly 1 includes a first expansion and torsion assembly and a second expansion and torsion assembly. The first expansion and torsion assembly is located above the second expansion and torsion assembly. The first expansion and torsion assembly can respectively expand and twist two layers of stator conductors to improve expansion efficiency. In other embodiments, only one first expansion and torsion assembly can be provided, that is, the expansion and twisting of one layer of stator conductors can be performed at a time.
[0045] Alternatively, as Figure 8 and Figure 9 As shown, the first torque expansion assembly includes a first torque expansion member 1031, with a first protrusion 10311 disposed on the first end of the first torque expansion member 1031, the first protrusion 10311 protruding toward the side of the second torque expansion member, and a wire insertion slot disposed on the first protrusion 10311. The second torque expansion assembly includes a second torque expansion member 1041, with a second protrusion 10411 disposed on the first end of the second torque expansion member 1041, the second protrusion 10411 protruding toward the side of the first torque expansion member, and a wire insertion slot disposed on the second protrusion 10411.
[0046] During specific implementation, the stator is located above the first torque expansion component, and the openings of the wire insertion slots on the first protrusion 10311 and the second protrusion 10411 are both facing upward. In this embodiment, the first torque expansion component 1031 is located above the second torque expansion component 1041, with the first protrusion 10311 protruding downward and the second protrusion 10411 protruding upward, so that the opening of the wire insertion slot on the first protrusion 10311 and the opening of the wire insertion slot on the second protrusion 10411 are in the same plane. In addition, the arrangement of the first protrusion 10311 toward the side of the second torque expansion component can reduce the vertical height of the second protrusion 10411, thereby reducing the torque applied to the second protrusion 10411 when the second torque expansion component performs torque expansion operations on the wires, thereby extending the service life of the second torque expansion component 1041.
[0047] Optionally, the main body 131 includes a first portion 1311 and a second portion 1312 that are detachably connected, with the wire insertion slot provided on the first portion 1311 and the follower portion 132 provided on the second portion 1312. Because the wire insertion slot is provided on the first portion 1311, during multiple expansion and torsion cycles, the first portion 1311 is subjected to greater external forces than the second portion 1312, making the first portion 1311 more susceptible to damage than the second portion 1312. When the first portion 1311 is damaged, the connection between the first portion 1311 and the second portion 1312 can be released, and the first portion 1311 can be replaced independently without affecting the connection between the follower portion 132 and the drive disk 12.
[0048] Optionally, the follower 132 is rotatably connected to the body 131. When the driving disk 12 rotates relative to the limiting disk 11, the follower 132 can rotate in the helical groove 121, which can reduce the friction between the follower 132 and the groove wall of the helical groove 121.
[0049] Optionally, the slide groove 111 includes a first groove 1111 and a second groove 1112 that are connected, and the end of the first groove 1111 away from the second groove 1112 passes through the limit plate 11, and the first part 1311 is slidably set in the first groove 1111 and the first end extends out of the limit plate 11, and the first groove 1111 and the second groove 1112 form a step surface in the radial direction of the stator, and the second part 1312 is slidably set in the second groove 1112 and can abut the radial step surface. The radial step surface is used to limit the distance that the torque expander 13 moves in the slide groove 111, and when the second part 1312 abuts the radial step surface, it is considered that the movement of the torque expander 13 toward the stator side is in place. At this time, the wire can be inserted into the wire insertion slot to perform the expansion action.
[0050] Optionally, the torque expansion mechanism further includes a drive assembly 2, which includes a torsion drive member and an expansion drive member. The output end of the torsion drive member is connected to the limit plate 11, and the torsion drive member is used to drive the limit plate 11 to rotate. The expansion drive member is disposed on the limit plate 11, and the limit plate 11 is used to drive the expansion drive member to rotate. The output end of the expansion drive member is connected to the drive plate 12, and the expansion drive member is used to drive the drive plate 12 to rotate. In a specific implementation, the expansion drive member causes the drive plate 12 to rotate. At this time, the limit plate 11 remains stationary, and the drive plate 12 and the limit plate 11 rotate relative to each other, thereby allowing the torque expansion member 13 to move in the slide groove 111 of the limit plate 11 along the radial direction of the stator. When the expanding action is completed, the torsion drive member can drive the limit plate 11 to rotate. Since the expanding drive member is provided on the limit plate 11, when the limit plate 11 rotates, the expanding drive member will move synchronously with the limit plate 11, and since the output end of the expanding drive member is connected to the drive plate 12, the limit plate 11, the expanding drive member and the drive plate 12 will rotate synchronously at this time, so that the torsion expander 13 rotates around the axial direction of the stator.
[0051] Preferably, the expansion-torsion integrated machine further comprises a truss, the torsion driving member is arranged on the truss, and the torsion driving member except the output end remains relatively fixed to the truss.
[0052] Optionally, a first drive gear 25 is provided at the output end of the torsion drive member, and first transmission teeth 112 are provided circumferentially around the limit plate 11. The first drive gear 25 is capable of meshing with the first transmission teeth 112. When the torsion drive member drives the first drive gear 25 to rotate, the first drive gear 25 can drive the limit plate 11 to rotate through engagement with the first transmission teeth 112. In this embodiment, the torsion drive member is a motor, and the first drive gear 25 is connected to the output shaft of the motor. Rotation of the output shaft of the motor can rotate the first drive gear 25. Preferably, a speed reducer is provided between the output shaft of the motor and the first drive gear 25. The speed reducer can reduce the rotational speed of the output shaft of the motor to increase the output torque of the output shaft.
[0053] Optionally, a second drive gear 26 is provided at the output end of the flaring driver, and second transmission teeth 122 are provided circumferentially around the drive disc 12. The second drive gear 26 is capable of meshing with the second transmission teeth 122. When the flaring driver drives the second drive gear 26 to rotate, the second drive gear 26 can drive the drive disc 12 to rotate through the meshing transmission with the second transmission teeth 122. In this embodiment, the flaring driver is a motor, and the second drive gear 26 is connected to the output shaft of the motor. Rotation of the motor output shaft rotates the second drive gear 26. Preferably, a speed reducer is provided between the output shaft of the motor and the second drive gear 26. The speed reducer can reduce the rotational speed of the motor output shaft to increase the output torque of the output shaft.
[0054] In this embodiment, the torque expansion mechanism further includes a mounting plate, which is disposed around the outer periphery of the limiting plate 11, and the first transmission tooth 112 and the expansion drive member are both disposed on the mounting plate. The first transmission tooth 112 is disposed on the end face of the mounting plate located in the axial direction of the stator. The first transmission tooth 112 is an annular structure and is coaxial with the limiting plate 11. In addition, because the drive plate 12 and the limiting plate 11 are coaxially disposed, when the mounting plate is disposed around the outer periphery of the limiting plate 11, the mounting plate can also be located outside the drive plate 12. The expansion drive member is fixed to the mounting plate, and a transmission hole is provided on the mounting plate, so that the second drive gear 26 disposed on the output shaft of the expansion drive member can be inserted into the transmission hole, thereby abutting against the second transmission tooth 122 located on the outer periphery of the drive plate 12.
[0055] In this embodiment, the mounting plate includes a first mounting plate 1051 and a second mounting plate 1052 . The first mounting plate 1051 is arranged around the outer periphery of the first limiting plate 1011 , and the second mounting plate 1052 is arranged around the outer periphery of the second limiting plate 1012 .
[0056] Alternatively, as Figures 2 to 5 As shown, the first torque expander assembly further includes a first limiting plate 1011 and a first drive plate 1021. The follower portion 132 of the first torque expander 1031 is located within the helical groove 121 of the first drive plate 1021, and the main body 131 of the first torque expander 1031 is located within the slide groove 111 of the first limiting plate 1011. The torsion drive member includes a first torsion drive member 21. A first drive gear 25 disposed at the output end of the first torsion drive member 21 is capable of meshing and transmitting with first transmission teeth 112 disposed circumferentially on the first limiting plate 1011. The flaring drive member includes a first flaring drive member 23. A second drive gear 26 disposed at the output end of the first flaring drive member 23 is capable of meshing and transmitting with second transmission teeth 122 disposed circumferentially on the first drive plate 1021.
[0057] The second torque expansion assembly also includes a second limiting plate 1012 and a second drive plate 1022. The follower portion 132 of the second torque expander 1041 is located within the helical groove 121 of the second drive plate 1022, and the main body 131 of the second torque expander 1041 is located within the slide groove 111 of the second limiting plate 1012. The torsion drive member also includes a second torsion drive member 22. A first drive gear 25 disposed at the output end of the second torsion drive member 22 is capable of meshing and transmitting with the first transmission teeth 112 disposed circumferentially on the second limiting plate 1012. The flaring drive member also includes a second flaring drive member 24. A second drive gear 26 disposed at the output end of the second flaring drive member 24 is capable of meshing and transmitting with the second transmission teeth 122 disposed circumferentially on the second drive plate 1022.
[0058] Alternatively, as Figure 4 As shown, the torque expander assembly 1 further includes a cover plate 14, which is disposed on the limiting plate 11. The cover plate 14 presses the main body 131 against the slide groove 111 in the axial direction of the stator. In this embodiment, the slide groove 111 provided on the limiting plate 11 passes through the limiting plate 11 along the axial direction of the stator. During assembly, the torque expander 13 can be first placed on the driving plate 12, with the follower portion 132 of the torque expander 13 located in the helical groove 121 and the main body 131 of the torque expander 13 located above the driving plate 12. Then, the limiting plate 11 is placed above the driving plate 12, with the main body 131 extending into the slide groove 111. The main body 131 includes a first part 1311 and a second part 1312 which are detachably connected, and the connection position between the two is located in the slide groove 111. A wire insertion slot is provided on the first part 1311 to connect the wires. If the first part 1311 needs to be replaced during multiple expansion and twisting processes, there is no need to remove the limit plate 11. Instead, the connection between the first part 1311 and the second part 1312 can be released to remove the first part 1311 from the slide groove 111.
[0059] In other embodiments, the slide groove 111 on the limit plate 11 can also be set as a stepped groove in the axial direction of the stator. That is, when the limit plate 11 is placed above the driving plate 12, the stepped surface in the axial direction of the stator can press the side of the main body 131 away from the driving plate 12 to prevent the torque expander 13 from detaching from the slide groove 111.
[0060] Optionally, the expansion and torque expansion machine further includes a tooth guard mechanism, which is used to drive the stator to move in the axial direction of the stator and position the stator above the expansion and torque expansion mechanism. In specific implementation, the tooth guard mechanism and the expansion and torque expansion mechanism are both arranged on the truss.
[0061] The above embodiments merely illustrate the basic principles and features of the present invention. The present invention is not limited to the above embodiments. Various changes and modifications are possible without departing from the spirit and scope of the present invention. Such changes and modifications are within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
