Description

Technical Field

[0001] This invention belongs to the field of electrical machinery and equipment technology, specifically relating to a fixing and issuing device for a flat wire stator layering machine. Background Technology

[0002] After the flat wire stator is inserted with the hairpin wires, the hairpin wires need to be layered outwards in pairs for subsequent twist welding. Therefore, the hairpin layering equipment is used to layer the stator hairpins. There are two main challenges in layering the flat wire stator hairpins outwards in pairs: firstly, ensuring that the pairs of flat wire hairpins enter the layering mold; and secondly, separating the hairpins introduced into the layering mold by the required distance. After the flat wire stator is inserted with the hairpin wires, it cannot be guaranteed that all the hairpin wires in each slot will be straight and not tilted outwards. Currently, the method for introducing the pairs of hairpin wires into the layering mold is to process a relatively large chamfer at the entrance of the layering mold, using the chamfer size to eliminate the influence of hairpin wire tilt. When the stator hairpin wire insertion quality is good, the pairs of hairpin wires... The hairpins can be introduced into the layered mold cavity through the chamfering of the layered mold. However, if the hairpins are severely tilted or have been bumped during storage and transportation, causing significant tilting, they need to be manually straightened; otherwise, they cannot smoothly enter the layered mold cavity. Another method is to create a height difference between pairs of hairpins, with the outer two hairpins being the tallest, the inner two the next tallest, and the very innermost two the shortest. Because of the uneven hairpin lengths, subsequent processes require cutting off the longer hairpins, resulting in wasted hairpins. Summary of the Invention

[0003] In order to overcome the shortcomings of the above-mentioned technologies, the purpose of this invention is to provide a simple and efficient fixing and issuing device for a flat wire stator layering machine.

[0005] Beneficial effects This invention employs a combined cam structure. First, protective teeth safeguard the root of the hairpin wire. Then, grippers clamp the hairpin wire and move it to a specific position, ensuring accurate positioning and allowing it to smoothly enter the layering mold cavity later. Furthermore, it avoids the waste caused by cutting off hairpins later due to increased height differences. This invention improves the stability and automation level of the flat wire stator layering machine while reducing production costs for manufacturers, making it highly valuable for widespread application.

[0009] The working steps of a fixing and issuing device for a flat wire stator layering machine are as follows: like Figure 1 , 2As shown, the right electric cylinder 5 extends, driving the protective tooth advance / retreat turntable 7 to rotate.

[0010] This invention solves the problem that in the original structure, when separating the hairpin wires of a flat wire stator, a large tilt of the hairpin wire could not guarantee smooth entry into the separation mold cavity, potentially causing collisions or requiring manual straightening of the tilted hairpin wire. This invention uses grippers to hold the hairpin wire and move it to a specific position, ensuring accurate positioning and thus guaranteeing smooth entry into the separation mold cavity. Furthermore, it avoids the waste caused by increased hairpin height differences during later hairpin cutting. This invention improves the stability and automation level of the flat wire stator separation machine while reducing production costs for manufacturers, making it highly valuable for widespread application.
