电动机端盖定子压合装置

Motor end cover stator pressing device

Abstract

The utility model relates to motor assembly processing equipment and particularly relates to a motor end cover stator pressing device. The device is provided with a floating plate, a stator pressing fixture upper mounting plate and a lower template. The middle part of the lower surface of the floating plate is provided with a guide plate. The center of the lower surface of the guide plate is provided with a spherical groove. The floating plate is provided with stepped holes which are internally provided with compression springs. Screws with gaskets pass through the stepped holes on the floating plate and are connected with the lower template. Two ends of each of the compression spring are respectively in contact with an upper stepped hole lower end face and the lower surface of a gasket. The center of the upper surface of the lower template is provided with a cylindrical ball head which is sleeved into the spherical groove of the guide plate, and the lower template and the guide plate are movably connected and a gap is formed between them. Four corners of the floating plate are respectively provided with a guide sleeve. The four corners of the lower surface of the stator pressing fixture upper mounting plate are respectively and correspondingly provided with a guide column which is coaxial with the guide sleeve. The motor end cover stator pressing device has the advantages of simple structure and safe and reliable operation, a phenomenon that pressing surfaces are not in parallel when pressing an end cover and a stator is eliminated, and an electromagnetic sound caused by the poor assembly of the end cover and the stator is prevented.
本实用新型涉及电动机装配加工设备,特别是一种电动机端盖定子压合装置,设有浮动板、定子压入治具上安装板和下模板,浮动板的下表面中部有导正板,该导正板下表面中央有球形凹槽,浮动板上设有阶梯孔,该阶梯孔内有压缩弹簧,带有垫片的螺钉穿过浮动板上的阶梯孔与下模板连接,压缩弹簧的两端分别与上阶梯孔下端面和垫片的下表面接触,在下模板上表面中央设有柱形球头,该柱形球头套入所述导正板的球形凹槽内,使下模板与导正板之间有间隙的活动连接,浮动板四角分别设有导套,所述定子压入治具上安装板下表面四角分别对应设有与导套同轴的导柱。本实用新型结构简单,操作安全可靠,消除端盖与定子压合时压装面不平行的现象,杜绝因端盖与定子装配不良而造成的电磁音。
