[0002] In the inductor winding process, the clamping fixture is a key positioning component, and its performance directly affects the winding accuracy and yield. Traditional fixtures need to simultaneously meet two core requirements: stable inductor clamping and adjustable winding position. They must prevent inductor displacement during winding and adapt to the processing requirements of inductors of different specifications. This places high demands on the structural design and driving method of the fixture.

[0018] The beneficial effects of this utility model are as follows:

[0019] This utility model relates to a clamping fixture based on inductor winding. The clamping mechanism uses an elastic clamping arm that engages with a movable component to hold the inductor.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components.

[0036] like Figures 1 to 6 As shown, this utility model presents a clamping fixture 100 based on inductor winding, used to clamp an inductor 200. Figure 7 As shown, the inductor 200 to be clamped by the clamping fixture 100 is shown. The inductor 200 is provided with a clamping base 210 and a winding groove 220. The clamping base 210 is used to cooperate with the clamping fixture 100 to achieve clamping, and the winding groove 220 is used for winding copper wire.

[0037] Please see Figure 1 , Figure 2 and Figure 4 The clamping fixture 100 based on inductor winding of this utility model includes a fixed base 10, a drive shaft 20, a connecting block 40, a rotating shaft 30, a clamping component 50, and a movable component 60. The drive shaft 20 is rotatably connected to the fixed base 10 and one end extends out of the fixed base 10 and connects to the connecting block 40. The rotating shaft 30 is fixedly connected to the connecting block 40. The clamping component 50 includes an integrally formed connecting sleeve 51 and at least two elastic clamping arms 52. The connecting sleeve 51 is sleeved on one end of the rotating shaft 30, and the elastic clamping arms 52 are located on one end of the connecting sleeve 51 and extend along the axial direction of the connecting sleeve 51. The inner side of the elastic clamping arms 52 forms a clamping cavity for clamping the inductor 200. The movable component 60 is sleeved on the outer side of the elastic clamping arms 52. The outer wall of the elastic clamping arms 52 is provided with a first conical extrusion surface 521, and the inner circular surface of the movable component 60 is provided with a second conical extrusion surface 61 that cooperates with the first conical extrusion surface 521.

[0038] In practical applications, the inductor 200 is located between the elastic clamping arms 52, and the movable member 60 has a first position and a second position. For example... Figure 3 and Figure 4 As shown, when the movable member 60 is in the first position, the first conical pressing surface 521 and the second conical pressing surface 61 press against each other, causing the elastic clamping arm 52 to contract radially inward along the connecting sleeve 51, thus clamping the clamping base 210 of the inductor 200 and thereby clamping the inductor 200. Conversely, when the movable member 60 is in the second position, the first conical pressing surface 521 and the second conical pressing surface 61 separate, and the elastic clamping arm 52 expands radially outward along the connecting sleeve 51 under its own elasticity, thus releasing the inductor 200. By achieving the mutual pressing or separation of the first conical pressing surface 521 and the second conical pressing surface 61 through the axial displacement of the movable member 60, the radial contraction and expansion of the elastic clamping arm 52 can be controlled, efficiently completing the clamping and release of the inductor 200 and meeting the winding requirements of the inductor 200.

[0039] The drive shaft 20 is used to connect the drive device 400. During the winding process, the drive device 400 drives the drive shaft 20 to rotate. At this time, the connecting block 40, the rotating shaft 30 and the clamping member 50 rotate synchronously, thereby causing the inductor 200 to rotate so that the copper wire can be wound in the winding groove 220.

[0040] Please see Figure 1 and Figure 2 The mounting base 10 provides a foundation for the installation of various components. Multiple rotating bearings 11 are embedded in the mounting base 10, and these bearings 11 are sleeved on the outside of the drive shaft 20 to ensure relative rotation between the drive shaft 20 and the mounting base 10. Additionally, the mounting base 10 has clearance grooves 12 to allow clearance for parts, providing installation space and resulting in a compact overall structure.

[0041] Please see Figure 1 and Figure 2 A transmission gear 21 is fixedly provided on the outer wall of the transmission shaft 20. The transmission gear 21 is used to connect the drive device 400 and realize the rotation of the transmission shaft 20 through gear transmission. Specifically, the transmission gear 21 is installed in the clearance groove 12.

[0042] Please see Figure 2 A cylindrical connecting part 31 is provided in the middle of the rotating shaft 30. The cross-sectional radius of the connecting part 31 is larger than that of the rotating shaft 30. During assembly, the connecting sleeve 51 is fitted onto the outside of the connecting part 31. At this time, the inner wall of the connecting sleeve 51 is in close contact with the outer wall of the connecting part 31. The connecting part 31 can increase the contact area between the rotating shaft 30 and the connecting sleeve 51, thereby improving the contact stability between them. In addition, as... Figure 4 As shown, the end of the rotating shaft 30 away from the transmission shaft 20 extends into the clamping cavity. When the inductor 200 moves a certain distance along the axial direction of the rotating shaft 30 and extends into the clamping cavity, the clamping base 210 of the inductor 200 will abut against the rotating shaft 30 to prevent the inductor 200 from entering the clamping cavity too deeply and to prevent obstruction in the winding groove 220, which would affect the winding quality.

[0043] Please see Figure 2 The elastic clamping arm 52 has clamping surfaces 522 with different angles. When the elastic clamping arm 52 is fully retracted, the clamping surfaces 522 form a closed frame. The shape of the closed frame matches the outer edge of the clamping base 210 of the inductor 200 to ensure clamping stability.

[0044] Please see Figure 1 and Figure 2It also includes a first elastic element 70. The outer wall of the movable member 60 is provided with an abutment ring 62. The first elastic element 70 is sleeved on the outside of the clamping member 50. In this embodiment, the first elastic element 70 is a metal spring. One end of the first elastic element 70 is connected to the abutment ring 62, and the other end of the first elastic element 70 is connected to the connecting block 40. In the automatic state, the elastic force of the first elastic element 70 pushes the movable member 60 to move away from the connecting block 40, so that the first conical extrusion surface 521 and the second conical extrusion surface 61 remain in a state of mutual extrusion during the winding process. That is, the elastic clamping arm 52 always clamps the inductor 200, preventing the inductor 200 from loosening and affecting the winding quality.

[0045] Please see Figure 1 and Figure 2 Both sides of the connecting block 40 are provided with wire end clamping assemblies. The wire end clamping assembly includes a connecting arm 41 fixed to the side of the connecting block 40 and a wire end clamping member 42 fixed to the connecting arm 41; the wire end clamping member 42 is used to clamp the wire end. In this embodiment, each side is provided with two wire end clamping assemblies, that is, a total of four wire end clamping members 42 are provided, which can simultaneously wind two sets of copper wires to meet the complex copper wire winding requirements. The wire end clamping component 42 includes a guide rod 421, a sliding member 422, and a second elastic element 423. The sliding member 422 is slidably connected to the outside of the guide rod 421, and the second elastic element 423 is sleeved on the outside of the guide rod 421. One end of the second elastic element 423 is connected to the sliding member 422, and the other end of the second elastic element 423 is connected to the connecting arm 41. A plug 424 is provided at the end of the guide rod 421 away from the connecting arm 41. The second elastic element 423 drives the sliding member 422 to move along the guide rod 421 toward the plug 424 to clamp the wire end.

[0046] The working principle of the clamping fixture 100 based on inductor winding involved in this utility model is as follows:

[0047] like Figure 5 As shown, when it is necessary to clamp the inductor 200, the clamping fixture 100 based on inductor winding of this utility model needs to be used in conjunction with the unloading device 300. The unloading device 300 includes a linear motor 310 and a pusher block 320. During operation, the linear motor 310 drives the pusher block 320 to move axially along the rotating shaft 30. The pusher block pushes the movable part 60 to compress the first elastic element 70. At this time, the elastic clamping arm 52 expands radially, allowing the inductor 200 to be inserted. After the inductor 200 is inserted between the elastic clamping arms 52, the linear motor 310 drives the pusher block 320 to retract. At this time, under the elastic force of the first elastic element 70, the movable part 60 resets, causing the elastic clamping arm 52 to contract radially, thereby clamping the inductor 200.

[0048] like Figure 6As shown, when winding is required, the clamping fixture 100 based on inductor winding of this utility model needs to be used in conjunction with the driving device 400. The driving device 400 includes a lifting motor 410, a lifting base 420 connected to the lifting motor 410, a driving motor 430 mounted on the lifting base 420, and a gear set 440 mounted on the lifting base 420; the driving motor 430 and the gear set 440 are driven to rotate; during operation, the lifting motor 410 drives the lifting base 420 to move downward, so that the gear set 440 meshes with the transmission gear 21, and at the same time the driving motor 430 drives the gear set 440 to rotate, and the transmission gear 21 rotates accordingly, thereby driving the connecting block 40 and the clamping member 50 to rotate synchronously, so as to meet the winding processing requirements.

[0049] Compared to existing technologies, the clamping fixture 100 based on inductor winding involved in this utility model clamps the inductor 200 by cooperating with the elastic clamping arm 52 in the clamping member 50 and the movable member 60. The conical extrusion surface structure between the elastic clamping arm 52 and the movable member 60 can control the radial contraction and expansion of the elastic clamping arm 52 through the axial displacement of the movable member 60, which ensures the reliability of inductor 200 clamping and avoids damage to inductor 200. In addition, the power transmission through the drive shaft 20, connecting block 40 and rotating shaft 30 enables the clamping member 50 to rotate synchronously to meet the processing requirements of rotary winding. It realizes the integrated function of inductor 200 clamping and rotary winding, and the structure is reasonable and compact. In addition, the integrated wire end clamping component can fix the position of the wire end during the winding process, effectively solving the problem of wire end loosening in traditional winding processes. This fixture has a compact overall structure and all components work together to achieve precise control of the clamping force of the inductor 200 and maintain stable rotational accuracy during the winding process. This greatly improves the yield and production efficiency of the inductor 200 winding and is suitable for large-scale automated production of inductors 200.

[0050] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
