In the following, taking the pressing component 12 located above the bearing component 11 as an example, the technical solution of the embodiment of the present application is further explained and explained in combination with one of the working flows of the coil fixture 100.

First, the caulking part 12 is disposed at a distance from the carrier part 11, and the coil 500 is placed on the carrier part 11. Then, the caulking part 12 is driven to move downward, so that the caulking part 12 and the bearing part 11 clamp and fix the coil 500 from both upper and lower sides of the coil 500. Then, the caulking part 12 is driven to move upward, so that the caulking part 12 is separated from the bearing part 11. Then, the positioning post 13 is driven to move downwards until the first end 131 is separated from the coil 500 supported by the supporting member 11. Finally, the coil 500 carried by the carrier member 11 is taken out.

It can be understood that, on the one hand, in the process that the coil jig 100 clamps and fixes the coil 500, the positioning column 13 can be inserted into the hole at the middle part of the coil 500 to accurately position the coil 500, and then the position accuracy of the coil 500 can be greatly improved when the coil jig 100 transports, bends, shapes or maintains pressure of the coil 500. On the other hand, when the coil 500 in the coil fixture 100 needs to be taken out, the positioning posts 13 can be firstly pulled out from the hole positions in the middle of the coil 500.

The coil fixture 100 can be applied to a coil shaping device as an example. Please refer to fig. 3, fig. 3 is a schematic structural diagram of a coil shaping device according to an embodiment of the present disclosure. The coil shaping apparatus may further include a frame 200, a first driving part 300, and a second driving part 400. The frame 200 is fixedly connected to the bearing member 11.

Illustratively, the first connecting structure 133 may be a threaded hole, and the second driving component 400 of the coil shaping device is in threaded connection with the threaded hole to realize the transmission connection between the second driving component 400 and the positioning column 13. For example, the second drive member 400 may be a cylinder, the piston rod of which is threaded into the threaded bore.

Of course, in some other embodiments, the first connecting structure 133 may also be a snap hole, a threaded column, or the like, which is not limited in this application.

To facilitate the placement of the coil 500 on the bearing member 11, the first end 131 of the positioning column 13 may be provided with a guiding structure to guide the coil 500 during the process of placing the coil 500 on the bearing member 11 from the top to the bottom.

For example, in the direction of the bearing part 11 toward the pressing part 12, or from bottom to top, the outer side surface of the first end 131 of the positioning column 13 is inclined toward the direction close to the axial line of the positioning column 13, and then the inclined surface formed by the outer side surface of the first end 131 can be used as the above-mentioned guiding structure.

In some embodiments, the pressing member 12 has a second through hole 121 opening toward the positioning post 13, and when the pressing member 12 presses the coil 500 carried on the carrying surface 111, the first end 131 is inserted into the second through hole 121.

first, the caulking part 12 is disposed at a distance from the carrier part 11, and the coil 500 is placed on the carrier part 11. Then, the heating assembly 14 starts to heat the bearing component 11 and/or the pressing component 12 until the heating assembly 14 stops heating after the temperature detection assembly 15 detects that the heating assembly 14 heats the bearing component 11 and/or the pressing component 12 to a proper temperature. Then, the caulking part 12 is driven to move downward, so that the caulking part 12 and the carrier part 11 perform caulking shaping on the coil 500 from both upper and lower sides of the coil 500. Finally, after the coil 500 is pressed and shaped for a certain time, the pressing member 12 is driven to move upward and the coil 500 is taken out from the carrier member 11.

Furthermore, during the shaping process of the coil 500, at least part of the stress inside the coil 500 can be eliminated by heating the coil 500, and finally, the spring back of the coil 500 after the press-fit component 12 is separated from the carrier component 11 can be reduced. The temperature detection assembly 15 is used for detecting the temperature of the shaping assembly; furthermore, the heating temperature of the heating assembly 14 can be detected by the temperature detecting assembly 15, so as to adjust the heating temperature of the heating assembly 14 by manual or automatic adjustment of other external devices, so that the coil 500 can be shaped at a proper temperature.
