具体实施方式
为使本实用新型实施例的目的、技术方案和优点更加清楚，下面将结合本实用新型实施例的附图，对本实用新型实施例的技术方案进行清楚、完整 地描述。显然，所描述的实施例是本实用新型的一部分实施例，而不是全部的实施例。
基于所描述的本实用新型的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本实用新型保护的范围。除非另外定义，本公开使用的技术术语或者科学术语应当为本实用新型所属领域内具有一般技能的人士所理解的通常意义。

如附图1-2所示，一种超高速电磁铁，包括骨架3，骨架3外围设有线圈部，骨架3内轴向设有腔体10，所述腔体10中安装有与线圈部对应的滑杆部，所述线圈部用以通电产生磁场以驱使所述滑杆部轴向往返运动，线圈部包括固定套设于所述骨架3外围的第一线圈2、第二线圈4，第一线圈2、第二线圈4沿骨架3外周面32轴向排列分布，以用于在骨架轴向方向形成两个可同步变换磁极方向、且两个磁极方向总处于相异状态的磁场(即两个线圈彼此靠近的一端磁极相同)。
其中，所述滑杆部包括，
永磁体部6，所述永磁体部6磁场的两个磁极沿所述骨架3轴向分布；
传动杆780，固接于所述永磁体部6上。
改进后的电磁铁工作运行流程如图2-3所示：
如图3，以纸面方向作为参考，图中永磁体部6的磁极左端为S，右端为N，将第一线圈2、第二线圈4通过相应的接线引脚接入可改变电流方向的电路结构(此为现有技术，本文不做赘述)中，通入电流后第一线圈2所形成的磁场左为N’，右为S’，而第二线圈4所形成的磁场磁极方向则与第一线圈2为异向，即磁场左为S”，右为N”。此时第一线圈2的磁极N’会与永磁体部6的磁极S形成吸引力，第一线圈2的磁极S’、第二线圈4的磁极S”与永磁体部6的磁极N形成吸引力，而第二线圈4的磁极N”与永磁体部6的磁极N形成排斥力，在三个力量的配合作用下使得滑杆部向左端运动。
如图4，改变第一线圈2、第二线圈4中的电流方向，第一线圈2左端为磁极S’，右端为磁极N’，第二线圈4左端为磁极N”，右端为磁极S”。此时，第一线圈2的磁极S’会与永磁体部6的磁极S形成排斥力，第一线圈2的磁极N’、第二线圈4的磁极N”与永磁体部6的磁极S形成吸引力，而第二线圈4的磁极S”与永磁体部6的磁极N形成吸引力，在三个力量的配合作用下使得滑杆部向右端运动。
以上，通过双线圈接入电路形成两个磁极方向相异的磁场，再与磁极方向固定的永磁体部6配合，通过线圈电流方向的改变来切换磁场之间的配合作用力，达到推拉滑杆部做直线往返运动的目的。以往电磁铁中滑杆部是一个单纯的受力结构，其被动的接收磁场作用力从而运动。而改进后，滑杆部在受到双线圈磁场力之余，还通过其自身永磁体部6与双线圈磁场的配合加强这种受力，使得其能实现的运动行程更长、力量更足。此外，改进后的框 架式电磁铁无需弹簧，不受弹簧性能衰减的影响，使用寿命得到保证，且运行更加安静。
永磁体部6可以采用单个整体结构(永磁体常为永磁铁)，但在实际运用中，为了满足滑杆部行程需求可能永磁体部的体积会较大，而大体积结构难以安装，因此本案中的永磁体部6可以采用两个或以上的小永磁体60，而相邻小永磁体60之间夹持固定电工纯铁61，由此组合形成一个磁极方向固定且磁场力较大的永磁体部6，如图8所示。
腔体10开口端11、封闭端12可以根据具体需求来设置，一些实施例中，骨架3两端设有盖板5，对应在腔体10外端的盖板5留有开口形成开口端11，对应腔体10内端的盖板5全封闭形成封闭端12，所述传动杆固接于所述永磁体部6的外侧，即传动杆靠近开口端11。传动杆可以包括导杆7和导块8，导杆7具有一定长度以满足导块8与外部其他结构实现传动配合的距离需求，而导块8则与外部结构实现直接的传动，在滑杆部直线往返运动时，传动杆沿着开口端11内外运动。
沿所述骨架3外周面32形成有两个独立的环形槽9以分别安装所述第一线圈2、第二线圈4，两个环形槽9靠近的一端具有共同的隔墙30，背离的一端各自具有挡墙31，环形槽9可以将线圈稳定于其中，避免线圈松动影响磁场效果。同时在骨架3外围包覆有外壳1，对电磁铁内部形成保护。
又如图5-7所示，提供一种电磁铁组件，组件包括前述的超高速电磁铁以及辅助磁体101，辅助磁体101用于安装在超高速电磁铁外部且靠近永磁体部6一端，通过辅助磁体101与永磁体部6之间的磁场配合可以加强对滑杆部的作用力。
图5中，在相应产品结构上安装固定电磁铁，再将磁极方向固定的永磁 铁作为辅助磁体安放在电磁铁旁，且其位置对应滑杆部永磁体部6。如图中永磁铁左端为磁极N，右端为磁极S，那么滑杆部右行运动时，辅助磁体与永磁体部6的同性相斥作用力会帮助滑杆部右行行程更快、更长。而在滑杆部左行时，双线圈与永磁体部6之间的作用力大过辅助磁体的相斥作用力即可，此处可以根据具体的使用环境需求预先配套设置好组件，即使得辅助磁体101所产生的作用力能对滑杆部右行方向起到推力作用，又不至于完全阻碍滑杆部左行回收的运动。图4所示方案，适用于对滑杆部右行有相应需求的产品，如产品对滑杆部左行运动有加强的需求，也可以通过将调换辅助磁体使其磁极方向改变。
前述采用的辅助磁体101是磁极方向固定的永磁铁，虽然可以满足一定的需求，但无法对滑杆部往返两个方向都起到助力作用，因此优选的将铁芯线圈103作为辅助磁体安装在电磁铁一旁。安装时将铁芯线圈103接入可改变电流方向的电路结构中，如图5所示，当滑杆部右行时，铁芯线圈103所产生的磁场对滑杆部的永磁体部6形成相斥作用力，从而助力推动滑杆部右行；当滑杆部左行时，铁芯线圈103电流方向改变，磁场磁极对换，对永磁体部6产生吸引作用力，从而将滑杆部拉回。辅助磁体101与框架式电磁铁之间具有一定的间隔空间102，以更好的发挥磁场之间的配合作用，在安装至相应结构上时，可以通过塑胶或者不导磁材料实现辅助磁体的固定。
改进后的框架式电磁铁通过双线圈电流方向的改变达到双磁场方向的切换，并借助磁极方向固定的永磁体部6与双线圈磁场的配合，实现完全通过磁场作用力驱使滑杆部直线往返运动的目的，其行程长、噪音小以及使用寿命长。且通过辅助磁极的配合，对电磁铁的行程、传动力做出进一步的改善。
以上所述仅为本实用新型的优选实施例而已，并不用于限制本实用新型， 对于本领域的技术人员来说，本实用新型可以有各种更改、组合和变化。凡在本实用新型的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本实用新型的权利要求范围之内。
