Description

Technical Field

[0001] This utility model belongs to the field of transformer tooling technology, specifically to a tooling for transposing an S-bend of a transformer conductor. Background Technology

[0002] The winding of transformer coils is one of the key steps in transformer manufacturing, and its quality directly affects the transformer's performance and efficiency. Transposed conductors are a special type of conductor; by changing the arrangement of the conductors, current distribution can be optimized, eddy current losses reduced, and transformer efficiency improved. When selecting conductor materials, copper is the preferred choice due to its good conductivity and mechanical strength. For small-diameter copper conductors, S-bend transposition can be completed manually or with simple tools during the winding process, which is relatively simple and low-cost, suitable for small-scale production or laboratory research. However, as the conductor size increases, especially when using transposed conductors, the winding difficulty increases significantly. Large-diameter transposed conductors are thicker and heavier, requiring considerable effort from workers to complete the S-bend transposition manually or with simple tools. This results in high workload and long turnaround time, leading to low efficiency, difficulty in ensuring winding uniformity and tightness, and easy damage to the conductors during the winding process, affecting the overall performance of the coil. Utility Model Content

[0003] To address the problem of time-consuming, labor-intensive, and inefficient manual S-bend transposition of large-diameter transposed conductors during winding, this invention provides a transposition tooling for transformer conductors using S-bends.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] This utility model proposes a transformer conductor S-bend transposition tooling, including an installation platform, a fixing part installed on the installation platform for fixing the conductor, a ratchet assembly installed inside the installation platform, a rotating platform connected to the ratchet assembly, S-bend transposition posts symmetrically arranged on the rotating platform, and the conductor passing between two of the S-bend transposition posts; a ratchet wrench is connected to the ratchet assembly.

[0006] A limiting part is provided on the outer end of the S-bend transposition post, and the limiting part is used to fix the wire passing between the two S-bend transposition posts.

[0007] Preferably, the ratchet assembly includes a ratchet with a connecting hole, and the ratchet wrench is connected to the connecting hole;

[0008] The mounting platform is provided with a mounting cavity, in which the ratchet is rotatably mounted. A locking platform is installed in the mounting cavity at the side of the ratchet, and the locking platform provides one-way limiting for the ratchet.

[0009] A spring is connected to the mounting plate at a position away from the ratchet, and the spring is installed inside the mounting cavity;

[0010] A connecting platform is connected to the ratchet. The connecting platform is rotatably mounted in the mounting cavity, and one end of the connecting platform extends out of the mounting cavity. The outer end of the connecting platform is connected to the side face of the rotating platform away from the S-bend transposition post.

[0011] Preferably, a guide sleeve is provided on the side of the mounting platform away from the S-bend transposition post, and one end of the ratchet wrench passes through the guide sleeve.

[0012] Preferably, the limiting part includes a limiting plate, which is installed on the end of the S-bend transposition post, and a fixing member is provided on the S-bend transposition post at a position that fits against the outer end face of the limiting plate.

[0013] Preferably, the fastener includes a locking nut, which is screwed onto the S-bend transposition post; a wrench holder is provided on the outer end face of the locking nut.

[0014] Preferably, the fixing part includes a connecting plate, one end of which is fixedly connected to the mounting platform. The connecting plate has symmetrically arranged clamping plates on the end face of the connecting plate on the same side as the S-bend transposition column, and the distance between the two clamping plates is less than the distance between the two S-bend transposition columns.

[0015] Preferably, an arc-shaped groove is provided on the inner wall of the card plate along its length, and the openings of the arc-shaped grooves on the two card plates are opposite each other.

[0016] Preferably, a second anti-slip pad is provided on the outer wall of the connecting plate at a position away from the mounting platform.

[0017] Preferably, the ratchet wrench is in the shape of a "7".

[0018] Preferably, a second anti-slip pad is provided on the outer wall of the ratchet wrench.

[0019] Compared with the prior art, the present invention has the following beneficial technical effects:

[0020] This utility model proposes a transformer conductor S-bend transposition fixture. The fixture's fixing part on the mounting table can firmly clamp the conductor, ensuring that the conductor will not shift or loosen during the transposition process, thereby guaranteeing the quality and accuracy of the transposition. The combination of the ratchet assembly and the rotary table allows the conductor to easily bend between the two S-bend transposition posts. The operation of the ratchet wrench enables precise control of the rotary table, improving the stability and reliability of the transposition operation. The limiting part on the outer end of the S-bend transposition post can effectively restrict the conductor placed between the two S-bend transposition posts, preventing the conductor from slipping or misaligning during the transposition process. This fixture has a simple structure, is easy to operate, and has ideal transposition effect and high work efficiency, greatly reducing the labor intensity of workers and improving the efficiency and quality of transformer manufacturing and maintenance work.

[0021] Furthermore, the connecting hole on the ratchet of this fixture can securely connect to the ratchet wrench, ensuring that the ratchet is driven stably and powerfully during operation. The mounting cavity inside the mounting platform provides sufficient space and support for the ratchet's rotation, allowing it to rotate smoothly and steadily. The clamping table can unidirectionally limit the ratchet, effectively preventing it from rotating on its own when no force is applied, thus ensuring the accuracy and stability of the repositioning operation. The spring allows the clamping table to move flexibly when under force, ensuring both unidirectional ratchet limiting and avoiding operational difficulties caused by excessive limiting. The connecting table allows the ratchet and the rotary table to be securely connected together, ensuring that they can rotate synchronously during the repositioning process. At the same time, one end of the connecting table extends out of the mounting cavity, facilitating connection with the rotary table and further improving the convenience of the repositioning operation.

[0022] Furthermore, this tooling has a guide sleeve on the side of the mounting platform away from the S-bend transposition post, and one end of the ratchet wrench passes through the guide sleeve to increase the stability of the connection between the ratchet wrench and the connecting hole.

[0023] Furthermore, this fixture features arc-shaped grooves along the length of the inner wall of the clamping plate, with the openings of the arc-shaped grooves on the two clamping plates facing each other. This makes the clamping of the wire between the clamping plates more flexible and stable. The arc-shaped grooves can adapt to the shape of the wire, reducing friction and wear between the wire and the clamping plate. At the same time, it ensures that the wire can maintain a stable posture during the transposition process, improving the reliability of wire clamping and extending the service life of the fixture.

[0024] Furthermore, the second anti-slip pad on the outer wall of the connecting plate enhances the operator's grip stability when using the tool, effectively preventing operational errors caused by hand slippage. The "7"-shaped ratchet wrench allows the operator to perform rotation operations with less effort, improving work efficiency. The second anti-slip pad on the outer wall of the ratchet wrench ensures operational stability and safety, avoiding injury or tool damage caused by wrench slippage, and improving the ease of use and safety of the transformer conductor S-bend transposition tool.

[0035] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0036] See Figures 1-4This utility model proposes a transformer conductor S-bend transposition fixture, including a mounting platform 6, which is cylindrical. A fixing part 4 is mounted on the outer wall of the mounting platform 6 for fixing the conductor 11. The fixing part 4 includes a connecting plate 40, one end of which is fixedly connected to the outer wall of the mounting platform 6, and the upper end face of the connecting plate 40 is flush with the upper end face of the mounting platform 6. Simultaneously, the length direction of the connecting plate 40 is perpendicular to the axial direction of the mounting platform 6, and the lower end face of the connecting plate 40 is flush with the upper end face of the mounting platform 6. The device is equipped with a clamping plate 41, which is set along the length of the connecting plate 40. The two clamping plates 41 are used to place the wire 11 and fix the wire through the clamping plates 41. The inner walls of the two clamping plates 41 are provided with arc-shaped grooves along their length. The openings of the arc-shaped grooves on the two clamping plates 41 are opposite each other. When fixing the wire 11, the wire 11 is clamped in the arc-shaped groove for fixation, so as to prevent the wire from falling off the clamping plate 41 during the S-bend transposition process and affecting the S-bend transposition of the wire 11.

[0037] Preferably, a second anti-slip pad is provided on the outer wall of the connecting plate 40 at a position away from the mounting platform 6, thereby increasing the stability of the connecting plate 40 during use.

[0038] See Figure 1 and Figure 2 A rotary table 5 is connected to the ratchet assembly 9, and the top end face of the rotary table 5 is attached to the bottom end face of the mounting platform 6. Two S-bend transposition posts 3 are symmetrically arranged on the bottom end face of the rotary table 5. The length direction of the two S-bend transposition posts 3 is perpendicular to the bottom end face of the rotary table 5. When performing S-bend transposition on the wire 11, the wire 11 is placed between the two S-bend transposition posts 3. The rotary table 5 is rotated by the ratchet assembly 9, and one end of the wire 11 is fixed by the two clamping plates 41. Then, by rotating the two S-bend transposition posts 3, the wire 11 is completely transposed at the S-bend transposition posts 3, thus realizing the S-bend transposition.

[0039] See Figures 1-3 A ratchet wrench 8 is connected to the ratchet assembly 9. The ratchet wrench 8 is in the shape of a "7" and the end of the "7" is connected to the ratchet assembly 9. The ratchet wrench 8 enables the ratchet assembly 9 to start working. A second anti-slip pad is provided on the outer wall of the ratchet wrench 8 at a position away from the ratchet assembly 9. The second protective pad protects the palm of the hand when the person holds it.

[0040] See Figures 1-3The mounting platform 6 has a mounting cavity 60, and a ratchet assembly 9 is installed in the mounting cavity 60. The ratchet assembly 9 includes a ratchet 90, which has a connecting hole 93. One end of a ratchet wrench 8 is connected to the connecting hole 93. A clamping table 91 is installed on the side of the ratchet 90 in the mounting cavity 60. The clamping table 91 limits the ratchet 90 in one direction, that is, by limiting it, the ratchet 90 can only rotate in one direction within the mounting cavity 60. The ratchet assembly 9 enables the tooling to stably handle the wire 11. A spring 92 is connected to the platform 91 at a position away from the ratchet 90. The spring 92 is installed in a mounting hole in the mounting cavity 60. When the ratchet 90 is rotated by the ratchet wrench 8 at a certain angle, and the ratchet wrench 8 is readjusted in the position of the connecting hole 93, the spring 92 pushes the locking platform 91 to limit the ratchet 90, so as to prevent the force of the wire 11 to recover its deformation during the bending process from driving the ratchet assembly 9 to rotate, thereby making the wire 11 return to its initial state and affecting the S-bend repositioning of the wire 11.

[0041] A connecting platform 50 is connected to the lower end face of the ratchet 90. The connecting platform 50 is rotatably installed in the mounting cavity 60, and the lower end of the connecting platform 50 extends out of the mounting cavity 60. The outer end of the connecting platform 50 is connected to the side face of the rotary table 5 away from the S-bend transposition post 3. The rotary table 5 can reduce the friction between the ratchet 90 and the inside of the mounting cavity 60, thereby extending the service life of the ratchet 90.

[0042] See Figure 1 and Figure 2 A guide sleeve 7 is provided on the end face of the mounting platform 6. The inner diameter of the guide sleeve 7 is larger than the maximum diameter of the connecting hole 93. One end of the ratchet wrench 8 is inserted into the guide sleeve 7. The guide sleeve 7 increases the stability of the connection between the ratchet wrench 8 and the connecting hole 93.

[0043] See Figures 1-4 A limiting part is provided on the outer end of the S-bend transposition post 3. The limiting part is used to restrict the wire 11 that passes between the two S-bend transposition posts 3. The limiting part includes a limiting plate 2, which is installed on the end of the S-bend transposition post 3. A fixing member is provided on the S-bend transposition post 3 at a position that fits against the outer end face of the limiting plate 2. The fixing member includes a locking nut 10, which is screwed onto the S-bend transposition post 3. A wrench holder 1 is provided on the outer end face of the locking nut 10.

[0044] When using the tooling, take it to the position of the wire 11 that needs to be repositioned. When repositioning the S-bend, remove the locking nut 10 from the S-bend repositioning post 3, place the wire 11 between the two S-bend repositioning posts 3, and place the other end of the wire 11 into the arc-shaped groove on the two clamping plates 41 on the fixing part 4. Hold it tightly by hand, and at the same time, screw the locking nut 10 onto the S-bend repositioning post 3. Secure it to the wrench holder 1 with a wrench and tighten the locking nut 10. Hold the ratchet wrench 8 and rotate it. After the S-bend meets the requirements of the drawing, stop rotating the ratchet wrench 8, remove the locking nut 10, take out the repositioning tooling, and the S-bend repositioning is completed.
