The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a three-phase alternating current brushless motor stator convenient for winding comprises a stator iron core ring 1, a bearing 2, a shaft lever 3, a first clamping groove 4, a second clamping groove 5, a fixed rod 6, a clamping block 7, a clamping plate piece 8, a winding rod 9 and a limiting block 10, wherein the bearing 2 is arranged on the inner side of the stator iron core ring 1, the shaft lever 3 is arranged on the inner side of the bearing 2, the first clamping groove 4 is arranged on the periphery of the outer wall of the bearing 2, the second clamping groove 5 is arranged on the periphery of the outer wall of the stator iron core ring 1, the fixed rod 6 is arranged in the second clamping groove 5, the clamping block 7 is arranged at one end of the fixed rod 6, the clamping plate piece 8 is arranged at the other end of the fixed rod 6, the winding rod 9 is arranged on the outer;

the clamping plates 8 and the limiting blocks 10 at the two ends of the winding rod 9 are distributed in a rectangular shape, the winding rod 9 is distributed in a flat shape, the winding rod 9 mainly plays a role in winding and fixing a coil, and the two ends of the winding rod 9 need to limit and block the winding rod when the coil is wound so as to prevent the coil from sliding out of the winding rod 9 and causing ineffective winding, so that the clamping plates 8 and the limiting blocks 10 can limit and block the two ends of the winding rod 9, thereby ensuring that the coil cannot slide out of the winding rod 9, and meanwhile, the clamping plates 8 also play a role in reinforcing and stabilizing the space between the winding rod 9 and the stator core coil 1;

the clamping plate pieces 8, the fixing rods 6 and the second clamping grooves 5 are distributed in an embedded mode, the second clamping grooves 5 are uniformly distributed along a circle of the stator iron core coil 1, the second clamping grooves 5 mainly have the effects that the clamping plate pieces 8 and the fixing rods 6 can be embedded and fixed, the clamping plate pieces 8 and the fixing rods 6 can be conveniently detached and inserted, most of ordinary stators are manually operated during later-stage maintenance winding, but the limiting blocks 10 on the periphery of the stators are distributed tightly, so that coil winding is extremely inconvenient, the winding rods 9 can be taken out at any time during later-stage maintenance through the embedded fixing mode, and therefore coil winding of the winding rods 9 is facilitated for operators;

the fixture block 7 at one end of the fixed rod 6 is embedded with the first clamping groove 4 on the outer wall of the bearing 2, and the first clamping groove 4 is uniformly distributed along the outer wall of the bearing 2, because the fixed rod 6 is movably connected with the stator iron core ring 1, and the stator iron core ring 1 cannot completely fix the fixed rod 6 through the second clamping groove 5, the fixture block 7 and the first clamping groove 4 have the effects of not only embedding and fixing the bearing 2 and the fixed rod 6, but also forming the fixed rod 6, the stator iron core ring 1 and the bearing 2 into a whole, and enabling the disassembly and assembly of parts to be more convenient through an embedded fixing mode;

the shaft lever 3 is movably connected with the stator iron core ring 1 through the bearing 2, the stator iron core ring 1 is distributed in a cylindrical shape, and the shaft lever 3 needs to rotate continuously during operation and the stator iron core ring 1 and the shaft lever 3 need to be movably connected, so that the bearing 2 has the effects of fixing the shaft lever 3 and the stator iron core ring 1 and enabling the shaft lever 3 to rotate smoothly;

dead lever 6 and fixture block 7, cardboard piece 8, wire winding rod 9 and stopper 10 are fixed an organic whole, and wire winding rod 9 is along stator iron core circle 1 a week evenly distributed, because it is fixed an organic whole between its wire winding rod 9 of ordinary stator device and stator iron core circle 1, and it is extremely inconvenient when carrying out coil winding operation in the later stage, consequently dead lever 6 and fixture block 7, cardboard piece 8, wire winding rod 9 and stopper 10 are fixed an organic whole and lie in can enough carrying out the block between wire winding rod 9 and stator iron core circle 1 and the bearing 2 and fix, make the dismouting between wire winding rod 9 and the stator iron core circle 1 and the bearing 2 more convenient simultaneously again, also further improve winding efficiency to the later stage.

The working principle is as follows: for the three-phase AC brushless motor stator convenient for winding, firstly, the fixing rod 6 and the clamping plate sheet 8 at one end of the winding rod 9 are inserted into the second clamping groove 5, so that a clamping structure is formed between the winding rod 9 and the stator core coil 1, then the first clamping groove 4 on the outer wall of the bearing 2 is embedded with the clamping block 7 at one end of the fixing rod 6, so that the winding rod 9, the stator core coil 1 and the bearing 2 are completely fixed, here, because the two ends of the winding rod 9 need to limit and block the winding rod 9 when winding coils, the coils cannot slide out of the winding rod 9, so that the clamping plate sheet 8 and the limiting block 10 can block and limit the two ends of the winding rod 9, thereby ensuring that the coils cannot slide out of the winding rod 9, and meanwhile, the clamping plate sheet 8 also plays a role in strengthening and stabilizing the winding rod 9 and the stator core coil 1, simultaneously, ordinary stator is mostly by manual operation when the later maintenance is twined, and because stator outlying stopper 10 distributes comparatively inseparably to it is extremely inconvenient when causing the winding coil, consequently can make winding rod 9 take out at any time when later stage maintenance through the fixed mode of gomphosis, thereby makes things convenient for operating personnel to carry out the coil winding to winding rod 9.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
