The utility model provides a stator coil dismantling device, which includes a top piece, an outer die, an inner mold and a driving mechanism, which is used to penetrate the core part of the winding. The outer die is a cylindrical structure; the inner mold is matched with the inner cavity of the stator; the stator is placed on the outer die so that the bottom end of the stator's iron core is limited to the upper end face of the outer die. The windings and the top parts exposed at the bottom of the core are placed in the inner cavity of the outer die, then the inner die is placed in the inner cavity of the stator and the top part is restricted to the inner cavity of the stator; the driving mechanism is started, the driving mechanism drives the internal mold to move down, the internal model drives the top part to move down, and the top part drives the coil to pull away from the iron core. The device has simple structure and high dismantling efficiency, and is suitable for various types of stator. Through the coordination of internal and external modules and top parts, the winding can be dismantled once and for all. In addition, the iron core will not be damaged because of the limiting action of the outer die step, and the iron core is limited to the step in the step in the process of pumping out of the line, so that the deviation will not occur to ensure the safety of the device.
【技术实现步骤摘要】
一种定子线圈拆除装置
本技术涉及电机维修
,具体来说是一种定子线圈拆除装置。
技术介绍
电动机定子的线圈缠绕在定子槽上,众多定子槽沿着定子的圆周分布。因此,定子线圈缠绕在定子槽上在定子的两端皆外露一定长度的闭合漆包线线圈端头。电动机定子线圈返修时,用錾子把线圈一端錾掉,再把槽楔去掉,最后把旧的漆包线拔出,或者用扁铁硬把线圈打出来,再清槽。由于定子槽数量众多,每槽皆需要这样做,一个人拆一台电机耗时长,成本高。
技术实现思路
本技术的目的是为了解决现有技术中采用人工拆除定子线圈,耗时耗力的缺陷,提供一种定子线圈拆除装置及线圈拆除方法来解决上述问题。为了实现上述目的,本技术的技术方案如下:一种定子线圈拆除装置,包括用于穿入绕组露出铁芯部分的连接部分的顶件、外模、内模、驱动机构;所述外模为筒状结构;所述内模与定子内腔相匹配;定子放置在外模上,使定子的铁芯的底端限位在外模的上端面,铁芯底端露出的绕组及顶件处于外模内腔,然后将内模放置在定子内腔后,并被顶件限位在定子内腔内;启动驱动机构,驱动机构驱动内模向下运动,内模带动顶件向下运动,顶件带动线圈从铁芯中抽离。优选的,所述外模的上端面具有限位台阶,铁芯限位在台阶内。优选的,所述顶件包括至少两根顶杆交叉组成。优选的,所述内模为与定子内腔相匹配的圆柱体。本技术还提供一种定子线圈拆除方法,使用上述的拆除装置进行线圈拆除;包括以下步骤:1)先将定子一端的绕组切断;2)在定子的另一端,用至少两根顶杆交叉穿入绕组露出铁芯部分的连接部分;3)将定子放置在外模上,使铁芯的底端限位在外模的台阶内;4)将内模放置在定子内腔;5)启动驱动机构 ...
