Under multiple actions, the threaded connection is gradually released.
  • the main reason for the failure of the threaded connection is that the thread is loose due to the reduction of the pre-tightening force. Therefore, the essence of the threaded connection is to prevent the reverse rotation of the thread pair (that is, the reverse between the threaded hole and the external threaded portion). Such as the reverse between the bolt and the nut.

Description

一种紧固连接组件及结构、安装及拆卸方法、曲轴连杆机构、轨道结构、骨连接装置及骨连接方法 技术领域:
本发明涉及一种螺纹副机械静联接两个以上的物体的紧固连接技术;特别是涉及一种通过螺纹副机械静连接曲轴连杆机构、轨道结构、飞机、船舶、设备、航空航天设备、航母、飞船、火箭、发动机、核反应设备、火车、高铁、铁轨、钢结构建筑、钢结构桥梁、汽车等等机械设备上的关键部位上的机械零件的紧固连接组件、紧固连接结构及连接方法、拆卸方法,这些机械零件的使用环境特别恶劣如震动大、高温环境、载荷大等,且对螺纹副机械静连接的连接可靠性要求特别高。
背景技术
物体间的螺纹副机械静联接出现一些关键部位连接的螺栓断裂、螺纹连接的失效引起的安全问题和安全事故,经常碰到,是全球面临的通病,也是本领域的技术人员不断研究改进急待解决还没有解决的问题。小螺栓、大事故,经常因螺栓断裂发生重大事故,如汽车的发动机的连杆螺栓断裂造成捣缸事故;2009年4月18日发生的哈尔滨塔吊螺栓断裂造成的1死4伤的事故;据台湾媒体报道的核二厂一号机反应炉检出7支锚定螺栓断裂、毁损可能引起核安全的事故;2012年6月29日16时45分发生的、5号座舱支撑系统的中导柱螺栓发生疲劳断裂、造成深圳东部华侨城“太空迷航”娱乐项目发生6人死亡、10人受伤的重大安全事故;作为高端车辆的代表厂家,因无法解决螺丝断裂的技术问题,导致宝马发动机因螺丝断裂瞬间失去动力熄火事件导致召回23万辆车(宝马(中国)汽车贸易有限公司、华晨宝马汽车有限公司决定自2014年6月18日起,召回23万辆车),制造厂家受到巨大经济损失和商誉损失,更严重的是会造成车主的生命财产安全。虽然在很多情况下,特别是在振动状态下,经常需要对已经锁紧的紧固连接件定期检修加固,防止螺纹副反转松动甚至是松脱带来的安全事故,但全世界每年因为螺纹连接失效导致的一系列安全事故非常多,例子不胜枚举。
螺纹连接的可靠性是靠螺纹副的摩擦产生自锁以及螺纹副的接触面间的摩擦来保证。一般来说,连接螺纹具有一定的自锁性,在静载荷条件下并不会自动松脱。但是,由于连接的工作条件不可避免地会存在冲击、振动、变载荷作用。在这些工况条件下,螺纹副之间的摩擦力会出现瞬时消失或减小;同时在高温或温度变化比较大的场合,材料会发生蠕变和应力松弛,也会使摩擦力减小。在多次作用下,就会造成螺纹连接的逐渐松脱。
螺纹连接的失效,主要原因是由于预紧力减少导致螺纹松脱,因此螺纹连接防松的本质,就是防止螺纹副的反转(也就是内螺纹孔与外螺纹部之间的反转),如螺栓与螺母间的反转。
现有的机械机械防松方法主要包括利用开口销、止动垫片及串钢丝绳等机械防松方法。现在飞机上很多还采用串联钢丝绳的防松方法。
为了防止螺纹连接松脱,人们一直在不懈努力。
专利号为US1755807、申请日为1929年4月6日、公开日为1930年4月22日的美国专利中,公开了一种防松的螺杆螺母结构,包括螺杆、锁紧螺母、止转套。锁紧螺母内设有螺纹通孔和与其连通的内齿轮形的止转孔,止转孔的最小孔径大于螺纹通孔的孔径。止转套设有止转通孔,止转套外周为外齿轮形,止转通孔孔壁上设有止转条,在螺杆上设有与止转条配合的止转槽。止转套的外齿轮形外周与锁紧螺母止转孔内齿轮型孔壁配合约束锁紧螺母相对止转套旋转,止转套的止转套插入螺杆的止转槽约束螺杆相对止转套旋转,因此螺杆与锁紧螺母不可转动地安装在一起。该专利中,由于止转套完全容置在锁紧螺母的止转孔中,止转套很难从锁紧螺母的止转孔中取出;而且在螺杆、螺母的使用过程中,由于止转套、螺杆和螺母生锈、灰尘进入止转套与螺杆和螺母间、止转套与螺杆和螺母的相互渗透等会造成止转套与螺杆螺母间产生很大的咬合力,从而造成止转套无法从螺杆与螺母间取出。如果止转套很难或无法从螺杆与螺母间取出,就很难或无法将螺母和螺杆分离,因而却失去了使用螺 纹副连接就是为了能够很方便地将螺杆和螺母分离的最基本用途,因而这种螺杆和螺母结构是没有多大的使用价值。
专利号为ZL201510198765.5、申请公布号为CN 104819197A、申请日为2015年4月24日、公布日为2015年8月6日的发明专利中,一种防松动螺母连接结构,包括连接件及穿过连接件的螺杆,螺杆上旋合螺母将连接件紧固,螺母外侧套接一防松套圈,防松套圈与连接件间设有防旋转结构,防旋转结构包括连接件上对应螺母设置的沉槽,螺母旋合后底部设于沉槽内,防松套圈外圈设有卡头,沉槽内侧壁设有供卡头卡入的卡槽;防松套圈高度小于沉槽的高度,防松套圈与螺母和沉槽之间为过盈配合。该发明的防松动螺母连接结构,由于增加了一个防松套圈,且防松套圈与连接件间设有防旋转结构,防松套圈内圈为与螺母配合的正六边形结构,防松套圈内圈与螺母间不能相对旋转,同时防旋转结构防止防松套圈与连接件相对旋转,因而可以防止螺母紧固后松动。这种防松动螺母连接结构,虽然实现了防止螺母的松动,但一方面由于防松套圈高度小于沉槽的高度、防松套圈与螺母和沉槽之间为过盈配合,在拆卸防松动螺母连接结构时,防松防松套圈是无法从沉槽内取出,无法取出防松防松套圈,就无法将螺母和螺杆分离,因而却失去了使用螺纹副连接就是为了能够很方便地将螺杆和螺母分离的最基本用途,,因而这种结构是没有任何意义的;另一方面,沉槽内侧壁设有供卡头卡入的卡槽,这种卡槽结构无法机械加工出来,如果不是事先与被连接件一起成型,则需要用电火花等工艺才能加工出来,因而使用成本特别高;还有,如果不对螺杆止转,螺杆相对锁紧螺母还是会转动,只对螺母止转也是没有任何现实意义。上述种种原因,会使本领域的技术人员认为该发明的技术方案无任何使用价值,大大阻碍了本领域的技术人员改进该专利的技术方案的积极性。
专利号为ZL97112246.6、公开日为97112246.6的发明专利中,公开了一种防松螺母,包括工具安装部及与其同轴向上突出设置的环形突出部,它们中间有贯通的螺纹孔。这种防松螺母,就是HardLock螺母,号称世界上唯一的绝不松动的螺母,是哈德洛克工业株式会社的社长若林克彦用了近20年的时间,通过不断技术改进而研究出来的技术成果,现在高铁上应用比较多。高铁运营时,高速行驶的列车和铁轨不断接触,形成的震动非常大,一般的螺丝在这种震动中会被震松震飞。不想被震飞,那么就需要螺丝和螺母丝丝入扣,永不松动才行。这个要求看起来很简单,但是要满足它并不容易。高铁代表中国创造,却用日本螺母,因而有媒体发出类似从一颗螺母看出中国制造和日本制造的差距的感叹。但这种螺母制造工艺非常复杂,制造精度要求特别高,现在的情况是,有产品图、有产品,没有哈德洛克公司的独特的技术和诀窍,却无法制造出来,因而价格昂贵,一个至少几十元钱;这种螺母也无法做到完全不松,只是在现有的防松螺母中防松效果算很好的;这种螺母,重复使用几十次后就不能再用。
专利号为ZL201520399393.8的实用新型专利中,公开了一种自紧螺母、螺栓紧固件,紧固件包括自紧螺母本体、自紧垫圈和普通螺栓;自紧螺母本体与自紧垫圈接触面为平滑过渡的螺旋面;自紧螺母本体与普通螺栓螺纹连接;螺栓紧固件包括自紧螺栓、自紧垫圈和普通螺母;普通螺母与自紧螺栓螺纹连接。该自紧螺母、螺栓紧固件,采用自紧原理,在螺母或螺栓上设置一自紧结构,使其锁紧后达到自紧的效果,让螺母不再出现移位或者松动。这种自己螺母,又称自紧王螺母和永不松动的螺母,并宣称其防松能力超过hardlock螺母,在央视中有报道。这种螺母由于没有广泛使用,其防松效果如何,无法判断。
公开号为CN201934467 U、公开日为2011年8月17日的实用新型专利中,公开了一种前端单螺纹螺旋式后双线锚固螺钉,它主要包括螺杆,螺杆上设有自攻螺纹,螺杆尾端设有连接结构件,连接结构件为外六角头,外六角头上设有垫片,垫片底部设有防松齿。该实用新型中,公开的仅是一种螺钉结构,所描述的所有结构均是螺钉结构的一部分,从图和外六角头上设有垫片的文字表达上来看,均可以毫无异议理解为垫片是螺钉的一部分,故不存在在垫片上设有与外六角头配合的止转通孔,垫片安装在外六角头外,垫片与螺杆是分开的两个构件。由于垫片是螺钉的一部分,在螺钉的旋入过程中,垫片及垫片上的防松齿也随着螺杆一起旋转,这样虽然在垫片上设有防松齿,防松齿在嵌入被连接的物体时并不是仅轴向嵌入被连接的物体,而是在旋转的过程产生轴向和周向位移嵌入被连接的物体,这样在螺钉旋转的过程中防松齿会在被连接物体的表面形成一条沿螺钉旋入方向由浅渐深的周向槽。周向槽一方面破坏被连接物体外观的美观;另一方面大大减小防松齿与被连接的物体的嵌入力, 可以说防松齿对螺钉的反向防松脱作用是十分有限的;特别是由于嵌入齿的存在,使螺钉很难锁紧被连接的物体。因此这种结构的螺钉的防松齿,是起不了放松的作用的,这种结构的螺钉,是没有任何使用价值的。
从专利号为US1755807、申请日为1929年4月6日的美国专利中,发明了用止转套来限制螺栓相对螺母转动的防松技术,到专利号为ZL201510198765.5、申请日为2015年4月24日的中国发明专利中,再次提出止转套来限制螺母转动的技术方案,历时八十六年,都没有解决既能用止转套对螺栓和螺母防松或用止转套对螺栓和螺母防松、又能方便快速可靠的将止转套从止转孔中取出从而使螺栓和螺母拆离的技术问题。现有的认为防松效果好的hardlock螺母、自紧王螺母,都不是通过采用止转套阻止螺母转动来实现螺栓螺母防松;快一个世纪过去了,还没有通过采用止转套阻止螺母转动来实现螺栓螺母防松的技术应用;可见,人们陷入了虽然采用止转套能阻止螺母转动来实现螺栓螺母防松、但螺栓螺母却很难或无法拆卸的技术误区,形成了采用止转套阻止螺母转动来实现螺栓螺母防松的技术无使用价值的惯性思维,从而阻止了本领域的技术人员改进采用止转套阻止螺母转动来实现螺栓螺母防松的技术方案的积极性
发明内容
针对现有技术中存在的问题,本发明要解决的技术问题是,克服现有的本领域的技术人员认采用止转套限制螺纹副反转松脱的防松技术方案、因止转套很难或无法从第一止转孔中取出、导致无使用价值的惯性思维,提供一种使螺杆不会因为反转而松脱且螺杆的拆离快速、方便、可靠的紧固连接组件及结构、安装及拆卸方法、曲轴连杆机构、轨道结构、骨连接装置及骨连接方法。
一种紧固连接结构,包括紧固连接组件、母体、附体;紧固连接组件包括螺杆;螺杆包括第一外螺纹部、止转抵挡部,止转抵挡部径向凸出第一外螺纹部;附体上设有与螺杆的第一外螺纹部配合的通孔;
紧固连接组件还包括止转套;
螺杆的止转抵挡部的外周设有轴向的第一止转部;
在止转套上仅设有一个轴向的止转通孔,止转通孔的孔壁上设有与螺杆的止转抵挡部的第一止转部配合、轴向的第二止转部;在止转套的外周设有轴向的第三止转部;
在附体背离母体的一侧设有第一止转孔,第一止转孔与附体上与第一外螺纹部配合的通孔连通并同轴,第一止转孔的孔径大于附体上的通孔孔径;或紧固连接结构还包括与附体不可转动地安装在一起的第一止转件,在第一止转件上设有第一止转孔;第一止转孔的孔壁与止转套的外周配合;在第一止转孔的孔壁上设有与第三止转部配合的第四止转部;
在第一止转孔的孔壁和/或止转套上、设有将安装在螺杆的止转抵挡部外和第一止转孔内的止转套取出的取出结构;
母体上设有螺纹孔,螺杆的第一外螺纹部穿过附体上的通孔与母体的螺纹孔螺纹连接,螺杆将母体和附体紧固连接在一起;或在母体上设有与螺杆的第一外螺纹部配合的通孔,在母体背离附体的一侧设有与母体不可转动地安装在一起的锁紧螺母,螺杆的第一外螺纹部穿过附体上的通孔、母体上的通孔与锁紧螺母螺纹连接,螺杆和锁紧螺母将母体和附体紧固连接在一起;
螺杆的止转抵挡部置于第一止转孔内,螺杆的止转抵挡部的第一止转部和第一止转孔的第四止转部位置关系对应;
止转套安装在螺杆的止转抵挡部外和第一止转孔内并被轴向限位在第一止转孔内;第一止转部与第二止转部配合约束螺杆的止转抵挡部相对止转套旋转;第三止转部与第四止转部配合约束止转套相对附体旋转,螺杆与附体、母体不可转动地安装在一起。
作为方案一的改进,取出结构包括设置在止转套上两个轴向的夹持孔或设置在止转套的外周上、与止转套外周连通的两个轴向的夹持凹陷部。
在止转套上设有两个以上用来将止转套从第一止转孔中夹持取出的夹持孔或夹持凹陷 部,取出止转套时,只需伸入两个夹持孔或夹持凹陷部内夹持住止转套从而将止转套从第一止转孔中取出,使止转套从第一止转孔中取出快速、方便、可靠。一般情况下可借助夹持工具夹持止转套将止转套从第一止转孔中取出,从而使止转套从第一止转孔中取出更加快速、方便且可确保止转套从第一止转孔中取出。
在止转套上设有两个以上用来将止转套从第一止转孔中夹持取出的夹持孔,不需在第一止转孔的孔壁上再设计取出止转套的结构,在成型止转套时成型夹持孔,几乎不增加成本,且止转套一般设计成标准件,因此可大大降低成本。
在止转套壁厚较薄、没有足够的空间设置夹持孔的情况下,在止转套外周设有夹持凹陷部结构,还可在第一止转孔的孔壁上设计与夹持凹陷部配合的结构形成一个夹持孔,在保证止转套刚性和强度的情况下,还能使夹持凹陷部的孔径满足夹持需要。
作为方案一的改进,取出结构还包括在止转套朝向第一止转孔的底面的一侧与第一止转孔底部形成与夹持孔或夹持凹陷部连通、供拆卸工具的夹持钩穿过夹持孔或夹持凹陷部进入的取出空间。
作为方案一的改进,取出结构包括设置在第一止转孔的孔壁上、与第一止转孔的孔壁及第一止转孔的顶面连通的两个取出槽。
作为方案四的改进,取出结构还包括在止转套朝向第一止转孔的底面的一侧与第一止转孔间设有与取出槽连通的取出空间。
作为方案一的改进,紧固连接组件包括第一止转件;
在止转套的外周设有六个以上周向均匀排列、轴向的第三止转部;
在第一止转件上设有一个以上的第一止转孔及贯穿相应的第一止转孔的底壁、与螺杆的第一外螺纹部配合、与第一止转孔同轴的通孔;在第一止转孔的孔壁上设有与止转套的第三止转部配合的第四止转部;
螺杆的第一外螺纹部穿过第一止转件上的通孔、附体上的通孔与母体安装在一起;
螺杆将母体、附体、第一止转件紧固连接在一起。
作为方案六的改进,在附体背离母体的一侧设有附体止转孔;
在第一止转件背离第一止转孔的一个端面上轴向凸出一个以上约束第一止转件相对附体转动、与附体止转孔配合的止转凸部;第一止转件的止转凸部插入附体止转孔内;螺杆的第一外螺纹部穿过第一止转件上的通孔、附体上的通孔与母体安装在一起;第一止转件的止转凸部插入附体的附体止转孔内、螺杆穿过第一止转件上的通孔共同约束第一止转件相对附体旋转;
或在止转套的一个端面上轴向凸出一个以上约束第一止转件相对附体转动、与附体止转孔配合的止转凸部,在第一止转件上设有与止转套的止转凸部配合的止转件止转孔;止转套安装在第一止转孔内,止转套的止转凸部穿过止转件止转孔插入附体止转孔内;螺杆的第一外螺纹部穿过第一止转件上的通孔、附体上的通孔与母体安装在一起;止转套的止转凸部插入附体的附体止转孔内、螺杆穿过第一止转件上的通孔共同约束第一止转件相对附体旋转。在附体上加工与第一止转件的止转凸部、止转套的止转凸部配合的附体止转孔,附体止转孔一般为圆孔,加工特别简单,加工成本低,一方面不需在附体上加工与第一止转件外周配合并需对第一止转件止转的止转件止转孔,大大降低成本;另一方面第一止转件与附体的拆离特别方便;还有第一止转件不需要与附体焊接固定等,使第一止转件相对附体也是随便可以拆卸的。
作为方案一的改进,在设有第一止转孔的附体上或设有第一止转孔的第一止转件上、对应每个第一止转孔均设有与第四止转部对应、过第一止转孔的轴线的径向的第一刻度线,第一刻度线分布在第一止转孔的外周。
一种紧固连接结构的拆卸方法,包括以下步骤:
用夹钳将止转套从第一止转孔中取出:夹钳包括可转动地枢接在一起地左钳体、右钳体,在左钳体的夹持端部的底面设有夹持凸柱,在右钳体的夹持端部的底面设有夹持凸柱,左钳体 的夹持凸柱、右钳体的夹持凸柱最大外径小于止转套的夹持孔或夹持凹陷部的最小孔径;将夹钳张开,左钳体的夹持凸柱、右钳体的夹持凸柱分别伸入相应的夹持孔或夹持凹陷部内,再收拢夹钳,夹钳将止转套从第一止转孔中取出;
再将螺杆从附体、母体中取出,完成紧固连接结构的拆卸。
用夹钳的两个夹持凸柱夹持止转套将止转套从第一止转孔中取出,不但止转套的取出快速、方便、可靠,且止转套上的夹持孔或夹持凹陷部不需要多大,就可以满足夹持的需要。从而可大大缩小止转套和与之相配的第一止转孔的尺寸,降低成本,更符合现有的紧固件的使用习惯。
作为方案九的改进,在止转套朝向第一止转孔的底面的一侧与第一止转孔底部、形成与夹持孔或夹持凹陷部连通的取出空间;
在左钳体的夹持凸柱的端部上、朝右钳体方向凸设有夹持钩,在右钳体的夹持凸柱的端部上、朝左钳体方向凸设有夹持钩;
左钳体的夹持凸柱和夹持钩、右钳体的夹持凸柱和夹持钩伸入相应的夹持孔或夹持凹陷部内且夹持钩径向伸入取出空间内,再收拢夹钳,夹钳的左夹持凸柱和右夹持凸柱夹紧止转套、左钳体的夹持钩和右钳体的夹持钩在背离止转套的取出方向抵挡止转套,夹钳将止转套从第一止转孔中取出。由于增加了夹持钩对止转套的抵挡,而不单纯是依靠夹持凸柱与止转套的夹紧摩擦力来夹持取出止转套,在拆卸紧固连接组件时,夹钳与止转套之间除了夹持摩擦力、还增加了夹持钩的轴向抵挡力,因而大大增加了夹钳夹持止转套的夹持力,可以非常可靠地取出止转套。
一种紧固连接结构的拆卸方法,包括以下步骤:
用夹钳将止转套从第一止转孔中取出:夹钳包括可转动地枢接在一起地左钳体、右钳体,在左钳体的夹持端部朝右钳体方向凸设有夹持钩,在右钳体的夹持端部朝左钳体方向凸设有夹持钩,左钳体的夹持端部和夹持钩、右钳体的夹持端部和夹持钩与取出槽配合,左钳体的夹持钩和右钳体的夹持钩与取出空间配合;将夹钳张开,左钳体的夹持端部和夹持钩伸入一个取出槽内且夹持钩径向伸入止转套与第一止转孔的底面间的取出空间内,右钳体的夹持端部和夹持钩伸入另一个取出槽内且夹持钩径向伸入取出空间内,再收拢夹钳,夹钳的左夹持端和右夹持端夹紧止转套、左钳体的夹持钩和右钳体的夹持钩在背离止转套的取出方向抵挡止转套,夹钳将止转套从第一止转孔中取出。
在第一止转孔的孔壁上设有两个取出槽,便于拆卸工具如夹钳从取出槽和取出空间夹持取出止转套,在拆卸紧固连接组件时,用拆卸工具夹持取出止转套,能非常省力、快速、快速、可靠地将止转套从第一止转孔中取出来。在止转套与第一止转孔间设有取出空间,在夹持取出止转套时,拆卸工具伸入取出空间内,这样不仅依靠夹持工具与止转套的夹紧摩擦力来夹持取出止转套,而且增加了拆卸工具对止转套在背离取出方向的抵挡力,因而可以非常可靠地取出止转套。在止转套和第一止转孔间增加取出槽和取出空间,特别适用于止转套壁厚薄和需较大的夹持力才能将止转套从止转孔中取出的情况;这种结构的紧固连接组件,若不在止转套和第一止转孔间增加取出结构,很难甚至无法将止转套从第一止转孔中取出;对因在使用过程中,止转套与第一止转孔间因生锈、灰尘等进入、长期使用产生止转套与第一止转孔咬合等导致止转套完全卡死在第一止转孔内的情况,借助拆卸工具,这种结构的紧固连接组件的止转套也能很可靠地从第一止转孔中取出。
一种紧固连接结构的安装方法,包括以下步骤:
将附体上的通孔正对母体上的通孔,螺杆的第一外螺纹部穿过附体上的通孔与母体安装在一起,螺杆将母体和附体安装在一起;螺杆的止转抵挡部置于第一止转孔内;
通过套筒扳手微调螺杆的止转抵挡部:在套筒扳手上设有与螺杆的止转抵挡部的外周面配合的止转抵挡部容置孔,在套筒扳手的止转抵挡部容置孔的外周面上设有与第一止转部和第一刻度线对应的轴向的第二刻度线,第一刻度线径向凸出套筒的外周;将套筒扳手套在螺杆的 止转抵挡部外,通过套筒扳手正向或反向旋转微调螺杆的止转抵挡部的角度使第二刻度线与第一刻度线共面,从而使螺杆的止转抵挡部的第一止转部与第一止转孔的第四止转部位置关系对应;
止转套安装在螺杆的止转抵挡部外和第一止转孔内,止转套被轴向限位在螺杆的止转抵挡部外和第一止转孔内;螺杆的止转抵挡部的第一止转部与止转套的第二止转部配合约束螺杆的止转抵挡部相对止转套旋转,止转套的第三止转部与第一止转孔的第四止转部配合约束止转套相对附体旋转,螺杆不可转动地与母体和附体安装在一起。
通过套筒扳手正向或反向旋转微调螺杆的止转抵挡部角度,因第一刻度线径向凸出第一止转孔、第一刻度线径向凸出套筒的外周,通过目测使第二刻度线与第一刻度线共面,从而很方便、准确地使螺杆的止转抵挡部的第一止转部与第一止转孔的第四止转部位置关系对应,使止转套能快速、准确地放置在螺杆的止转抵挡部外和第一止转孔内。
一种紧固连接结构的第一次安装方法,紧固连接组件包括第一止转件,第一止转孔贯通第一止转件;
安装方法包括以下步骤:
安装完螺杆后,将止转套安装在螺杆的止转抵挡部外,止转套的第二止转部置于螺杆的止转抵挡部的第一止转部外;
将第一止转件的第四止转部与止转套的第三止转部位置关系对应,再将第一止转件安装在止转套外,止转套的第三止转部安装在第一止转孔内;
将止转套轴向限位在螺杆的止转抵挡部的第一止转部外和第一止转孔的第四止转部内;
将第一止转件与附体固定;
第二止转部与第一止转部配合约束螺杆的止转抵挡部相对止转套旋转,第三止转部与第四止转部配合约束止转套相对附体旋转,螺杆不可转动地与母体和附体安装在一起。
第一次安装紧固连接结构时,在安装完止转套后再安装第一止转件,安装特别方便。在紧固连接组件重复使用的过程中,拆卸时,只需将止转套从第一止转孔中夹持取出,第一止转件还是固定在附体上;重新安装紧固连接组件时,由于螺杆的止转抵挡部相对第一止转孔的位置关系基本不会改变,因此螺杆的止转抵挡部不需要调整,拧紧螺杆的止转抵挡部,螺杆的止转抵挡部的第一止转部就和第一止转孔的第四止转部位置关系对应,再次重复安装安装特别方便。
一种紧固连接组件,包括螺杆,螺杆包括第一外螺纹部、止转抵挡部,止转抵挡部径向凸出第一外螺纹部;还包括止转套;螺杆的止转抵挡部的外周设有轴向的第一止转部;
在止转套上仅设有一个轴向的止转通孔,止转通孔的孔壁上设有与螺杆的止转抵挡部的第一止转部配合、轴向的第二止转部;在止转套的外周设有轴向的第三止转部;
在止转套上设有两个以上用来将止转套从第一止转孔中夹持取出的夹持孔或在止转套的外周设有两个以上用来将止转套从第一止转孔中夹持取出、与止转套外周连通的夹持凹陷部;
止转套安装在螺杆的止转抵挡部外,第一止转部与第二止转部配合约束螺杆的止转抵挡部相对止转套旋转。
作为方案十四的改进,还包括弹性垫圈。弹性垫圈可为蝶形弹簧或压缩弹簧或塔形弹簧等。弹性垫圈一般安装在螺杆的止转抵挡部和附体间。为了将止转套安装在螺杆的止转抵挡部外和第一止转孔内,需要使螺杆的止转抵挡部的第一止转部与第一止转孔的第四止转部位置关系对应,需正转或反转微调螺杆的止转抵挡部时,增加弹性垫圈,利用弹性垫圈的弹性变形来调节螺纹连接的预紧力,避免螺纹连接的预紧力过大或过小。
作为方案十四的改进,在止转套的一个端面上设有三个轴向凸出止转套端面、使止转套朝向第一止转孔的底面的一侧与第一止转孔底部形成与夹持孔或夹持凹陷部连通的取出空间的支撑部。支撑部与第一止转孔的底面形成与夹持孔或夹持凹陷部连通、供拆卸工具的夹持钩穿过夹持孔或夹持凹陷部进入的取出空间。
因在止转套上容易形成用来形成取出空间的支撑部,如可与止转套一起冲压而成,因而成本 低。
作为方案十四的改进,紧固连接组件还包括对止转套背离螺杆的第一外螺纹部的一侧轴向限位的止转套限位件;止转套限位件为卡环或为设有两个以上弹性卡扣的扣盖,卡环或扣盖的最大外径大于止转套的止转通孔的最小内径。可在螺杆上设有与卡环或扣盖配合的卡槽,也可在第一止转孔的孔壁上设有与卡环或扣盖配合的卡槽。安装紧固连接结构时,只需将卡环安装在卡槽内,或将扣盖的弹性卡扣扣在卡槽内,就可对止转套轴向限位。止转套限位件为扣盖,扣盖不但能对止转套背离止转抵挡部的一侧轴向限位,还有盖子的作用,使止转套和螺杆不会暴露在空气中,从而大大增加止转套和螺杆的使用寿命,使用更安全,外观更美观,扣盖还可起装饰作用。止转套限位件为卡环或扣盖,在螺纹联接容易失效的场合,卡环或扣盖轴向限位更可靠。
作为方案十四的改进,紧固连接组件包括第一止转件;
在止转套的外周设有六个以上周向均匀排列、轴向的第三止转部;
在第一止转件上设有一个以上的第一止转孔及贯穿相应的第一止转孔的底壁、与螺杆的第一外螺纹部配合、与第一止转孔同轴的通孔;在第一止转孔的孔壁上设有与止转套的第三止转部配合的第四止转部。
作为方案十八的改进,在第一止转件本体背离第一止转孔的一个端面上轴向凸出一个以上约束第一止转件相对附体转动的止转凸部;
或在止转套的一个端面上轴向凸出一个以上约束第一止转件相对附体转动的止转凸部,在第一止转件上设有与止转套的止转凸部配合的止转件止转孔;止转套安装在第一止转孔内,止转套的止转凸部插入止转件止转孔并凸出止转件止转孔。
作为方案十八的改进,第一止转件包括第一止转件本体,在第一止转件本体同一侧凸设有两个以上、与第一止转件上与螺杆配合的通孔同轴的扇形的凸出部,在凸出部的内侧壁上设有与止转套的第三止转部配合第四止转部;凸出部设有第四止转部的内侧壁形成非闭合的第一止转孔;取出结构为相邻两凸出部周向间的间隙形成的取出凹陷部。
这种结构的止转件一般为冲压件,冲压成型止转件上的通孔、第一止转孔和取出结构等,成本低;取出结构的周向间隙大,便于用手直接将止转套从第一止转孔中取出,而不需要专门的拆卸工具;特别是这种结构的第一止转孔为非闭合的止转孔,在使用过程中,止转套与止转件的咬合力会大大减小,进一步方便止转套不需要专门的工具就能从第一止转孔中取出。

在止转套上设有两个以上止转通孔,通过安装在止转套内的两个以上的螺杆的止转抵挡部、螺杆约束止转套相对附体旋转,不需要再设计其它止转结构,如不需要止转件,也不需要在附体上设计与止转套配合的止转结构来约束止转套相对附体旋转等,结构简单;拆卸时先拆卸止转套限位件,再直接将止转套与螺杆的止转抵挡部分离,在拆螺杆的止转抵挡部,拆卸时非常方便,不需要专门的工具。对一些母体、附体上与第一外螺纹部配合的孔的孔距相等且孔距比较小、或呈现某种固定的规则排列的紧固连接结构来说,特别适用。

采用本发明的紧固连接组件的轨道结构,通过紧固连接组件固定在一起的弹条和垫板,由于螺杆相对垫板、预埋套管不会旋转,因此即使弹条承受很大地力、或轨道结构处于剧烈震动的环境,螺杆和预埋套管的连接也很可靠,不会因为螺杆与预埋套管的螺纹连接副反转松脱导致螺纹连接失效,这样确保弹条可靠地压住绝缘块、绝缘块可靠地压住导轨,导轨可靠地与垫板安装在一起,防止事故发生。
本发明的有益效果是:
既要阻止螺纹副反转防松,又要保持机械螺纹连接的方便、快速、可靠地可拆卸性,是人们一直长期以来致力解决却没有彻底解决的技术难题。
本发明通过止转套限制螺杆相对母体、附体转动,从而使螺杆不可转动地安装在母体和附体上,防止紧固连接组件在使用过程中螺杆反转松脱。止转套与第一止转孔和螺杆抵挡部之间一般为间隙配合,便于止转套的安装和取出。
为了螺杆的止转抵挡部安装在第一止转孔内后,螺杆的止转抵挡部的第一止转部和第一止转孔的第四止转部位置关系能对应,在设计止转套时注意止转套的第二止转部与第三止转部的位置对应关系,也就是第二止转部与第三止转部要有对应的规律。
在第一止转孔的孔壁上和/或止转套上、设有将安装在螺杆的止转抵挡部外和第一止转件的第一止转孔内的止转套取出的取出结构,使止转套能方便、快速、可靠地从第一止转孔中取出,即使是止转套完全容置在第一止转孔中。止转套从第一止转孔中取出后,螺杆的拆卸与传统的螺杆拆卸完全是一样的,因而螺杆的拆卸方便、快速、可靠。
第一止转孔约束止转套相对附体旋转,第一止转部与第二止转部配合约束螺杆的止转抵挡部相对止转套旋转,这样螺杆无法转动,螺杆就不会因为反转而松脱,使螺杆保持在最初需要的锁紧位置,螺杆的螺纹连接的夹紧力在使用过程中基本无变化;即使采用普通的螺杆连接,在剧烈震动、高温等恶劣环境下,螺杆的螺纹连接的夹紧力在使用过程中基本无变化;因此达到最好的锁紧效果,能有效避免螺杆螺纹螺纹连接失效。
在止转套上仅设有一个止转通孔,紧固连接组件的适用范围广,不受母体和附体上用来安装螺杆的孔的孔距限制,但需在附体上设计对止转套止转的第一止转孔,或用相对附体无转动地第一止转件来约束止转套旋转;这种紧固连接结构,结构更紧凑,更符合通用的标准件紧固件的安装和使用习惯,可以设计成标准件。
这种结构的紧固连接结构,在螺杆的止转抵挡部的第一止转部与第一止转孔的位置关系没有通过计算事先确定的情况下,一般必须在螺杆的止转抵挡部的外周设有至少六个以上的第一止转部,在止转套的止转通孔上设有第一止转部整数倍的第二止转部,一个第一止转与一个以上的第二止转部配合;和/或在止转套的外周设有至少六个以上的第三止转部,在第一止转孔上设有六个以上的第四止转部,一个第三止转部与一个以上的第四止转部配合;这样才能保证螺杆连接的预紧力。

紧固连接组件,包括螺杆3、止转套4、止转套限位件。止转套限位件为抵挡螺母5。
螺杆3包括依次排列的第一外螺纹部6、光杆部7、止转抵挡部、第二外螺纹部8。止转抵挡部包括外周为圆柱形的抵挡圆凸环9和外周为花键形的止转部10,止转部10与第二外螺纹部8相连。止转部10的外周形成五个凸出部,每个凸出部形成一个第一止转部11。抵挡圆凸环9径向凸出光杆部7、止转部10,止转部10径向凸出第二外螺纹部8。
