[0021] Please refer to Figures 1-4 , Figures 1-4 which schematically shows the coil clamping and fixing structure according to the present utility model.

[0022] A coil clamping and fixing structure, characterized in that it comprises:

[0023] A bottom plate 1, a first pressing cylinder 2 and a bearing slide 13 arranged on the bottom plate. The first pressing cylinder 2 is connected with a first connecting plate 3. The first connecting plate 3 is rotatably connected with a first rotating rod 4 through the bearing slide 13. A first pin 5 is provided on the first rotating rod 4. A first spiral bronze bushing 6 cooperating with the first rotating rod 4 and the first pin 5 is provided on the first connecting plate 3. A first pressing block 16 is arranged at the top of the first rotating rod 4. The first connecting plate 3 is hinged with a second connecting plate 7. A first side pressing plate 8 is provided at the top of the second connecting plate 7. The first side pressing plate 8 is an inverted triangle. First side pressing blocks 9 which are slidably connected are provided on both sides of the first side pressing plate 8. When the second connecting plate 7 moves downward, the two first side pressing blocks 9 press the inner side of the coil.

[0024] In the present utility model, the first pressing block 16 and the first side pressing blocks 9 are driven by the first pressing cylinder 2 to press the coil. The first pressing block 16 presses the pins, restricting the up and down movement of the pins and preventing the coil from being distorted and deformed due to the twisting of the coil during the operation of the mechanism, thus solving the problem that the coil needs to be fixed and clamped during bending.

[0025] Among them, the first pin 5 is connected to the first rotating rod 4. Under the action of the cylinder, the first pin 5 rotates and lifts along the track of the first spiral bronze bushing 6, thereby driving the lifting of the first pressing block 16.

[0026] Among them, when the first pressing block 16 rotates and rises, a certain space will be left, facilitating the placement of the coil pins from top to bottom. As Figure 4 shown, it is the state where the first pressing block 16 is opened.

[0027] Among them, under the action of the first pressing cylinder 2, the first side pressing plate 8 moves downward, and the triangle becomes larger from smaller, squeezing the first side pressing blocks 9 to both sides.

[0028] Furthermore, it also includes a spiral seat 11 and a sealing plate 12. A hollow cylindrical channel is provided in the spiral seat 11. The first rotating rod 4 is connected to the first clamping block 16 through the hollow cylindrical channel. The sealing plate 12 is provided on one end of the spiral seat 11 away from the first clamping block 16.

[0029] Furthermore, the first pressing block 16, the spiral seat 11, the sealing plate 12 and the first rotating rod 4 form a coil pin to press the coil.

[0030] Furthermore, it also includes a first bearing 14 and a second bearing 15. The first bearing 14 is connected to the first side clamping plate 8. The first rotating rod 4 is slidably connected through the second bearing 15. During the rotation of the first rotating rod 4, the second bearing 15 pushes the first rotating rod 4 so that the first rotating rod 4 rotates freely.

[0031] Furthermore, a first locking block 17 is disposed above the first pressing block 16 .

[0032] The working principle of the utility model is as follows: the first clamping cylinder 2 retracts, all the first clamping blocks 16 are in the open state, the coil is put in, and then the first clamping cylinder 2 extends, the first connecting plate 3 drives the first rotating rod 4 to rotate and descend, the first side clamping plate 8 moves downward through the second connecting plate 7, and the first side clamping block 9 moves away from the center direction, thereby clamping the coil, and the first clamping block 16 rotates counterclockwise and descends to press the pin to limit the upward and downward movement of the pin.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions. The sentence "includes an element defined by ... does not exclude the existence of other identical elements in the process, method, article or device including the element".

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
