[0033] Example

[0034] Reference Figure 1-7 , the utility model provides an embodiment: a winding structure for off-line protection of a motor, including a base 1 and a flattening box 7, a sliding groove 2 is opened at the center of the upper end surface of the base 1 near both sides, two No. 1 sliding plates 3 are slidably connected in one of the two sliding grooves 2, and the copper wire spool can be installed and fixed, and two No. 2 sliding plates 8 are slidably connected in the other sliding groove 2, and the workpiece can be installed and fixed, and a rotating shaft 16 is rotatably provided at the upper end of the center of the two No. 1 sliding plates 3 on the opposite side, and a friction sleeve 15 is rotatably sleeved on the outer walls of the two rotating shafts 16, which can limit the rotation speed of the rotating shaft 16, and an extrusion plate 4 is fixedly provided on the opposite side of the two rotating shafts 16, so as to extrude and fix the copper wire spool, and two supporting rings 5 ​​are fixedly provided at the center of the opposite side of the two extrusion plates 4, and the copper wire spool can be sleeved on the supporting ring 5 to support the copper wire spool, and a No. 3 threaded rod 28 is fixedly provided at the upper end of the center of the opposite side of the two No. 2 sliding plates 8;

[0035] A support shaft 27 is fixedly provided at the center of the opposite side of the two No. 3 threaded rods 28. The outer wall of the No. 3 threaded rod 28 near the rear end of the two No. 3 threaded rods 28 is threadedly sleeved with a clamping mechanism 17, which can clamp the workpiece to facilitate the workpiece to rotate and move horizontally. The clamping mechanism 17 includes two telescopic rods 1701, two connecting plates 1702, a lower clamping ring 1703 and an upper clamping ring 1704. A transmission motor 19 is fixedly provided at the center of the rear end surface of the No. 2 sliding plate 8 near the rear end of the two No. 2 sliding plates 8 near the upper end, a sliding rod 10 is fixedly provided at the center of the upper end surface of the base 1 near the front end, and a No. 1 threaded rod 11 is rotatably provided at the center of the upper end surface of the base 1 near the rear end. A plurality of squeezing rollers 25 are rotatably provided at the center of the rear end surface of the inner wall of the flattening box 7 near the upper and lower ends. While rolling the copper wire flat, the tightness of the copper wire can be adjusted by adjusting the height of the flattening box 7;

[0036] When in use, firstly, the four No. 2 threaded rods 14 on the front and rear end surfaces of the two fixed plates 20 are rotated to one side through the handle 9, so that the two No. 1 sliding plates 3 and the two No. 2 sliding plates 8 are moved along the two sliding grooves 2 through the thread grooves 18 respectively, so as to adjust the spacing between the two No. 1 sliding plates 3 and the spacing between the two No. 2 sliding plates 8, and then the copper wire spool is sleeved on the support ring 5 through the support ring 5, and then the two No. 2 threaded rods 14 that penetrate the No. 1 sliding plate 3 are rotated to make the two No. 1 sliding plates 3 move toward each other, and the copper wire spool is squeezed and fixed by the two squeezing plates 4, and at the same time, one end of the workpiece is clamped on the inner wall of the lower clamping ring 1703;

[0037] Then, the upper clamping ring 1704 and the lower clamping ring 1703 are clamped and fixed by the sliding groove 23 and the sliding bar 24, so as to clamp the workpiece, and then the two No. 2 threaded rods 14 penetrating the No. 2 sliding plate 8 are rotated to make the two No. 2 sliding plates 8 move toward each other, and the multiple embedded blocks 21 on one support shaft 27 are embedded into the multiple embedded grooves 22 on the other support shaft 27, so that the joint between the two support shafts 27 is smoother and convenient for the workpiece to slide;

[0038] After the fixation is completed, the copper wire is passed through the opening 12 on one side into the flattening box 7, and after being flattened by the upper and lower rows of squeezing rollers 25, it is passed through the opening 12 on the other side and fixed on the workpiece. Then, the transmission motor 19 is started to drive the rotating ring 26 to rotate, and the upper clamping ring 1704 and the lower clamping ring 1703 are driven to rotate through the telescopic rod 1701. During the rotation process, the upper clamping ring 1704 and the lower clamping ring 1703 are driven by the thread along the No. 3 threaded rod 28 to drive the workpiece to rotate while moving horizontally along the support shaft 27, so as to evenly wind the copper wire on the workpiece.

[0039] When the workpiece is wound with copper wire, the copper wire spool will pass through the rotating shaft 16. During the rotation, the friction force generated by the friction sleeve 15 on the rotating shaft 16 makes the rotation speed of the copper wire spool roughly the same as the rotation speed of the workpiece, and the No. 1 threaded rod 11 can be rotated to drive the flattening box 7 to move downward along the slide bar 10 to achieve the tightening of the copper wire. When there is a difference in the rotation speed of the copper wire spool and the workpiece, the copper wire can be further tightened to prevent the copper wire from becoming loose and causing derailment when it is wound. The upper end positions of the slide bar 10 and the No. 1 threaded rod 11 can be limited by the top plate 6 to prevent the slide bar 10 and the No. 1 threaded rod 11 from being deformed by force during use, and the position of the top plate 6 can be fixed by four brackets 13.

[0040] Working principle: The workpiece is effectively fixed by the clamping mechanism 17, and the rotating ring 26 is driven to rotate by the transmission motor 19, so that the workpiece is driven by the clamping mechanism 17 to slide along the outer wall of the No. 3 threaded rod 28 during rotation, so as to achieve uniform winding of the copper wire and prevent uneven winding of the copper wire from affecting the use effect of the motor. The friction sleeve 15 can bring friction to the rotating shaft 16, so that the rotation speed of the rotating shaft 16 is roughly the same as the rotation speed of the workpiece. When there is a difference in the rotation speed, the copper wire can be tightened by adjusting the position of the flattening box 7 downward, and the copper wire can be flattened by using multiple squeezing rollers 25 to prevent the copper wire from loosening during the winding process and causing the wire to derail.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
