Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing, and in particular to a motor winding coil winding device. Background Technology

[0002] A coil is a loop or cylinder made of wire with an insulated outer sheath. Coils are an important component of motors. In the process of manufacturing motors, several sets of coils need to be evenly wound on the iron core. In the existing technology, coils with the required parameters are mostly wound by different winding dies.

[0003] A search of Chinese Patent Publication No. CN216072448U reveals a portable motor coil winding device, including a bracket with a winding machine and a reel mounted on it. The winding machine includes a base fixedly connected to the bracket. A column is mounted on the upper surface of the base, and three parallel gear shafts (first, second, and third) are horizontally arranged on the column. A first gear is connected to the end of the first gear shaft, a second gear is mounted to the end of the second gear shaft, and a third gear is mounted to the end of the third gear shaft. The first gear meshes with the second gear, and the second gear meshes with the third gear. A hand crank is connected to the other end of the shaft, and a winding frame is connected to the third gear shaft. When the hand crank is turned, the first gear shaft drives the second gear to rotate, and the second gear drives the third gear to rotate, thereby rotating the winding frame. The winding frame includes two parallel first baffles and second baffles. The middle of the first baffle and the second baffle are connected to the second gear shaft. Two spacing adjustment grooves are respectively provided on the first baffle and the second baffle. An upper wire groove frame is clamped between the upper end of the first baffle and the upper end of the second baffle by a set of fastening bolts. A lower wire groove frame is clamped between the lower end of the first baffle and the lower end of the second baffle by a set of fastening bolts.

[0004] In the prior art, before winding the coil, the end of the wire is usually wound around the gear shaft between two winding dies. In order to ensure the wire is fixed, the gear shaft is usually provided with several grooves to increase the friction between the gear shaft and the wire. This makes it difficult to remove the wire fixed on the gear shaft after winding multiple sets of coils. Utility Model Content

A driven gear 304 is fixedly connected to the drive shaft 202, and the driven gear 304 meshes with the drive gear 303.

[0021] The top of the base 1 is also provided with a wire feeding mechanism, which includes a first upright plate 501 fixedly connected to the top of the base 1, a first support rod 502 fixedly connected to the rear side of the first upright plate 501, a second upright plate 503 fixedly connected to the top of the base 1, a second support rod 504 slidably connected inside the second upright plate 503, the rear end of the second support rod 504 extending out of the second upright plate 503 and fixedly connected to a ball handle, a limit plate 505 fixedly connected to both the first support rod 502 and the second support rod 504, and a wire reel 506 inserted into the first support rod 502 and the second support rod 504, the wire reel 506 being located between the two limit plates 505.

[0022] An auxiliary mechanism is provided between the two sets of winding dies 204. The auxiliary mechanism includes a limiting plate 401. The front end of the drive shaft 202 extends out of the mounting plate 203 and is fixedly connected to the limiting plate 401. A central shaft 402 is installed on the front side of the limiting plate 401. Several grooves are provided on the central shaft 402 to ensure the fixation effect of the wire wound on the central shaft 402. The central shaft 402 is composed of two symmetrical parts. A limiting groove is provided on the front side of the limiting plate 401. Both parts of the central shaft 402 are slidably connected in the limiting groove.

[0023] An adjustment assembly is provided between the two central shafts 402. The adjustment assembly is used to adjust the distance between the two central shafts 402. The adjustment assembly includes two telescopic plates 404 arranged symmetrically at the top and bottom. A receiving groove is opened in the wall of the central shaft 402. The telescopic plates 404 slide in the receiving groove. A toggle block 405 is rotatably connected between the upper and lower telescopic plates 404. The two ends of the toggle block 405 are protruding semi-circles. A screw block 406 is rotatably connected to the top of the upper telescopic plate 404. The screw block 406 is fixedly connected to the toggle block 405. A slot is opened on the top of the screw block 406 to facilitate the use of tools such as screwdrivers to drive the screw block 406 to drive the toggle block 405 to rotate. Several springs 403 are fixedly connected between the two central shafts 402.

[0024] Working principle: In use, first pull the second support rod 504 backward so that the limiting plate 505 on the second support rod 504 abuts against the second upright plate 503. Then, insert one end of the spool 506 into the first support rod 502, and make the limiting plate 505 on the first support rod 502 abut against the spool 506. Then push and pull the second support rod 504 forward so that the second support rod 504 extends into the spool 506, thereby installing the spool 506. After installation, wind the end of the wire on the spool 506 onto the central shaft 402, and then wind it onto the two sets of winding molds 204. The rocker arm 302 drives the drive shaft 301 to drive the drive gear 303 to rotate. The drive gear 303 meshes with the driven gear 304, thereby driving the driven gear 304 to drive the drive shaft 202 to rotate. The drive shaft 202 drives the spool 506 to rotate. The mounting plate 203 drives the two sets of winding molds 204 to rotate, and the coil is started to be wound. After a certain number of turns, the wound coil is fixed with cable ties. Then, the remaining wire is cut after leaving a sufficient length. When it is necessary to remove the wound coil from the winding mold 204, the screwdriver is used to turn the screwing block 406, which drives the actuating block 405 to rotate 90 degrees. After the two central shafts 402 lose the pressure of the actuating block 405, they move towards each other under the action of the spring 403, which reduces the distance between the two central shafts 402, making it easier to remove the wire wound on the central shaft 402. Then, the nuts at both ends of the mounting shaft 205 are loosened in turn, and the two winding molds 204 are moved towards each other. Finally, the coil on the winding mold 204 is removed.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
