Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-4 As shown, this embodiment provides a coil winding support, including a winding frame 1. A rotating roller mechanism 2 is arranged above the winding frame 1. The rotating roller mechanism 2 includes an outer roller 3 and an inner roller 4. The outer diameter of the inner roller 4 matches the inner diameter of the outer roller 3. An inner limiting slot 301 is formed in an annular array on the inner sidewall of the outer roller 3. A limiting block 401 is installed at one end of the inner roller 4 corresponding to the position of the inner limiting slot 301. The limiting block 401 engages with the inner limiting slot 301. The outer side of the inner roller 4 is located at... A circular stop block 402 is installed at one end away from the limit block 401. A rotating bolt 403 is installed in a circular array inside the circular stop block 402. The rotating bolt 403 is engaged with the circular stop block 402 for rotational connection. A three-jaw chuck 405 is installed inside the inner insert roller 4. The three-jaw chuck 405 is fixedly connected to the inner insert roller 4. A rotating rod insertion hole 404 is opened on the side surface of the inner insert roller 4. A positioning claw 406 is arranged in an array inside the three-jaw chuck 405. A movable through hole is opened on the outer side wall of the inner insert roller 4 at the position corresponding to the positioning claw 406.

[0022] like Figure 2-3 As shown, in this embodiment, a rotating roller bracket 5 is installed on the outer side of both the outer roller 3 and the inner roller 4. A rotating bearing is installed inside the rotating roller bracket 5 on the outer side of both the outer roller 3 and the inner roller 4. A guide slider 501 is installed on the lower surface of the rotating roller bracket 5 located near the inner roller 4. A guide groove 6 is provided below the guide slider 501 on the upper surface of the winding frame 1. An extension slide rail 7 is installed on the side of the winding frame 1 near the guide groove 6. A rotating bracket is installed at one end of the winding frame 1 on the outer side of the extension slide rail 7. The rotating roller bracket 5 is slidably connected to the guide groove 6 through the guide slider 501. A positioning screw hole 8 is provided on the upper surface of the winding frame 1 on one side of the guide groove 6. A drive gear is installed on the outer side of the outer roller 3 located away from the inner roller 4.

[0023] The working principle of this utility model is as follows: When in use, the roller for winding the coil is first fitted onto the outside of the inner roller 4. The outer diameter of the inner roller 4 is smaller than the inner diameter of the roller. The position of the rotating rod insertion hole 404 of the inner roller 4 is left on the outside. Then, by applying torque to the rotating bolt 403 on the outside of the annular stop block 402, the rotating bolt 403 is controlled to abut against the end of the roller. The rotating rod is then inserted from the inside of the rotating rod insertion hole 404 into the inside of the inner roller 4 and then into the rotating hole inside the three-jaw chuck 405. The positioning jaws 406 on the three-jaw chuck 405 are then extended to abut against and limit the roller. Then, by pushing the guide slider 501 at the lower end of the roller bracket 5 on the outer side of the inner roller 4 inside the guide groove 6, the limiting block 401 at the end of the inner roller 4 is inserted into the inner limiting slot 301 inside the outer roller 3, completing the overall assembly of the outer roller 3 and the inner roller 4. After installing the limiting bolt inside the positioning screw hole 8 at the corresponding position, the roller mechanism 2 can be driven to drive the roller to wind the coil. After the winding is completed, the extension slide rail 7 is rotated and docked with the guide groove 6, and then the roller bracket 5 drives the inner roller 4 to move, so that the roller can be removed from the outside of the inner roller 4.
