[0002] The rotor coil is an important component in the motor. It is mainly used to generate a magnetic field on the rotating motor rotor, thereby interacting with the magnetic field on the stator to drive the motor to rotate.

[0026] The utility model provides the following technical solutions:

[0027] Embodiment 1

[0028] Combination Figures 1 to 6 A DC motor rotor coil winding bending device comprises a bending arm 1, a reinforcement mechanism 2 is arranged at the left end of the bending arm 1, a replacement mechanism 4 is arranged on the left side of the reinforcement mechanism 2, and a bending column 3 is arranged on one side of the replacement mechanism 4;

[0029] The reinforcement mechanism 2 includes a fixed box 21, which is fixedly connected to the left end of the bending arm 1. A spring 22 is fixedly connected to the inner wall of the fixed box 21. A slide plate 23 is fixedly connected to the end of the spring 22 away from the fixed box 21. An insert block 24 is fixedly connected to the side of the slide plate 23 away from the spring 22. A support frame 25 is fixedly connected to the top of the slide plate 23. A stop block 26 is provided at the left end of the bending arm 1. A limiting ring 27 is provided on one side of the replacement mechanism 4.

[0030] Furthermore, the left end of the bending arm 1 is fixedly connected to a long shaft, and the stopper 26 is rotatably connected to the outer wall of the long shaft, so that the stopper 26 can limit the support frame 25.

[0031] Furthermore, a bayonet is provided inside the limiting ring 27, and the insert block 24 is inserted into the inner wall of the bayonet. The limiting ring 27 is limited by the cooperation between the insert block 24 and the bayonet, thereby achieving the purpose of strengthening the connection.

[0032] Furthermore, a moving opening is opened on the top of the fixed box 21, and the support frame 25 passes through the moving opening and moves, so that the support frame 25 can push the slide plate 23 to move.

[0033] Furthermore, the slide plate 23 is slidably connected to the inner wall of the fixed box 21 , and the insert block 24 penetrates the left side of the fixed box 21 and moves, so that the slide plate 23 can move stably to compress the spring 22 .

[0034] Embodiment 2

[0035] See also Figures 1 to 6 On the basis of the first embodiment, the replacement mechanism 4 further comprises an empty cylinder 41, the empty cylinder 41 is fixedly connected to the right end of the bending column 3, the outer wall of the empty cylinder 41 is threadedly connected with a threaded sleeve 1 42, the left end of the bending arm 1 is fixedly connected with a threaded sleeve 2 44, and the left end of the threaded sleeve 2 44 is fixedly connected to the solid column 43, so as to facilitate the disassembly of the bending column 3.

[0036] Furthermore, the solid column 43 is movably connected to the inner wall of the hollow cylinder 41, the threaded sleeve 1 42 is threadedly connected to the outer wall of the threaded sleeve 2 44, and the limiting ring 27 is fixedly connected to the right end of the threaded sleeve 1 42 to improve the stability of the connection.

[0037] In actual operation, when this device is used, first, when the bending column 3 needs to be disassembled and replaced, the stopper 26 is rotated to allow the support frame 25 to move through the stopper 26, and then the support frame 25 can be pushed to move, and the support frame 25 can drive the slide plate 23 to compress the spring 22. At this time, the slide plate 23 will also drive the plug block 24 to disengage from the inside of the limit ring 27, canceling the reinforcement limit of the limit ring 27, and facilitating the further disassembly of the bending column 3. While achieving the purpose of disassembling and replacing the bending column 3, the stability of the connection and installation of the bending column 3 is also guaranteed. Under the mutual cooperation of the plug block 24 and the spring 22, it can be ensured that the connection will not easily produce shaking and deviation, thereby enhancing the practicality of the device;

[0038] When the limit on the limit ring 27 is cancelled, the threaded sleeve 42 can be rotated at this time. Since the threaded sleeve 42 and the threaded sleeve 44 are threadedly connected to the empty cylinder 41, the threaded sleeve 42 can be moved in the direction close to the bending column 3, so that the connection limit on the empty cylinder 41 and the solid column 43 is cancelled. Then the empty cylinder 41 can be pulled out from the outer wall of the solid column 43 to realize the disassembly of the bending column 3. Similarly, the installation of the bending column 3 can also be realized, which makes it convenient for the bending device to be suitable for processing operations in different processing environments, and the bending diameter can be flexibly adjusted. At the same time, good disassembly and replacement efficiency can be achieved.

[0039] 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 elements defined by the statement "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.
