Description

Technical Field

[0001] The invention relates to motor wire embedding, in particular to a wire embedding mechanism and an assembly method for motor wire embedding. Background Art

[0002] The stator is an important part of the motor. There are many occasions where motors are used in industrial products. Many electrical products use them as a driving power source. The stator is the main part of the motor. The main part of the stator is the coil. At present, the processing flow of the stator is mostly to wind the copper wire on the wire mold, and then manually embed the copper coil into the motor core. This processing method has many disadvantages: low efficiency; high requirements for manual skills, manual wire embedding is relatively loose, affecting the performance of the stator; many existing factories use wire embedding mechanisms to embed the wires, so as to ensure the performance of the stator; the wire embedding mechanisms currently used in factories are mostly equipped with fixed guide bars and push-in guide bars for use in combination, and the push-in guide bars are used to embed the wires. The coil is embedded in the stator core to complete the wire embedding work, but the fixed guide bars and push-in guide bars currently used generally have an annular array of mounting grooves on the fixed seat or the push block, and then a number of guide bars are installed in the mounting grooves for use. For example, a Chinese patent with publication number CN204179876U discloses a patent named "Wire embedding mold for multi-station wire embedding machine", which records the wire embedding mold for multi-station wire embedding machine, including a mouth guard, the mouth guard is a hollow cylinder, the inner wall surface of the mouth guard is evenly provided with mounting grooves, a storage strip is provided in the mounting groove, and a movable guide strip is connected to the storage strip, and the lower end of the mouth guard is provided with a countersunk hole, and a mouth guard bottom plate is provided in the countersunk hole. A mounting hole is provided in the middle of the bottom plate of the mouthguard, a connecting seat is provided in the mounting hole, guide bar holes corresponding to adjacent storage bars are evenly distributed on the bottom plate of the mouthguard in a circular shape, a guide bar seat is provided above the bottom plate of the mouthguard, the guide bar seat is connected to the connecting seat, a through hole is provided in the middle of the guide bar seat, a receiving cavity is provided at the upper end of the through hole, a clutch mechanism is provided in the receiving cavity, and the clutch mechanism is connected to a copper head of a push wire; however, this method is troublesome to assemble, generally a guide bar mounting groove of an annular array is provided on the fixed seat, and then several guide bars are installed one by one on the guide bar mounting groove, and a single guide groove is provided on each guide bar, which causes the fixed seat to be processed with guide bar mounting grooves corresponding to each guide bar. The grooves are complicated in production process and high in production cost. The assembly of each guide bar is complicated and time-consuming. The guide bars are independent and there are gaps between them, which results in weak rigidity and strength. Each guide bar needs to be assembled separately, which takes a long time to assemble. The guide bar has poor rigidity and strength. It is easy to deform due to force during use, which will cause pressure on the enameled wire, causing the enameled wire to deform or even wear, thus causing problems with motor performance. When one end of the guide bar is worn or otherwise damaged and cannot be used, it can only be replaced, but cannot be turned around and clamped for continued use. The cost is high, reassembly is troublesome, and the service life is short. To this end, a wire embedding mechanism and assembly method for motor wire embedding are proposed.
