【技术实现步骤摘要】
一种用于电梯、自动扶梯或自动人行道的失电附加制动器
本技术涉及一种辅助制动器,具体涉及一种用于电梯、自动扶梯或自动人行道的失电附加辅助制动器。
技术介绍
附加制动器(暨电磁铁),用于电梯、自动扶梯和自动人行道的附加制动的执行元件。在传统的制动器执行元件中,筒身和后端盖是一个整体,机加工切削刀在加工时只能从筒身口进入,距离过长,加工精度得不到保证,致使机加工成品率低。若采用机加工后再焊接后盖的方法,也会由于焊接时产生的高温因素,导致工件变形,精度无法保证,机加工成品率同样会低。在装配前端盖和筒身时,传统方法采用压机压铆连接,压铆后制动器就无法拆卸返修或者是调整,装配工艺性差,致使装配不良品相应增多,无形中增加了成本。
技术实现思路
本技术的目的是为了解决以上现有技术的不足,提供一种用于电梯、自动扶梯或自动人行道的失电附加辅助制动器,相较于传统的制动器具有加工精度高,方便拆卸维修,大批量生产时制造成本低的特点。本技术是一种用于电梯、自动扶梯或自动人行道的失电附加制动器,包括主轴、前端盖、后端盖、筒身、衔铁、铜质隔磁片、弹簧、线包和底板;所述底板焊接固定于筒身下部外壁;所述前端盖固定于筒身前端内侧,配合方式为过盈配合并通过多个螺丝和筒身固定连接;所述后端盖内壁上设置有内螺纹,筒身后端外壁设置有外螺纹,后端盖与筒身后端通过内、外螺纹实现连接;所述主轴设置并固定于衔铁内,且与筒身同轴并贯穿筒身和前、后端盖;所述线包设于筒身内壁,所述衔铁插入线包内并设置于主轴后端;所述铜质隔磁片固定在前端盖靠近衔铁端部;前端盖和衔铁相对位置处分别设有相对的定位孔,所述弹簧悬空缠绕在主轴上,弹 ...
