Description

一种半自动转轴组件 技术领域
本发明涉及飞行器技术领域，更具体地，本发明涉及一种半自动转轴组件。
背景技术
目前，市面上转轴的种类丰富多样，其应用领域及其广泛。通常来说，只要有旋转的地方，就有转轴的存在。
目前，在一类具有自锁及限位功能的转轴组件中，其包括轴芯、弹性垫片、自锁垫片、活动架、限位垫片、固定架、长孔垫片。转轴旋转时，自锁垫片旋转至一定的角度，设置自锁垫片的锁紧凸体卡入设置在活动架的凹部的底部的锁紧凹槽内，转轴即可进行自锁；同时，限位垫片也随着旋转，设置在其外侧的卡位与设置在活动架的凹部的上部的限位凸体相接处，可对转轴的旋转角度进行限位。这种结构自锁能力一般，无半自动功能。
在另一类转轴组件中，利用凸轮原理，将相对旋转的上、下离合部赋予两个相配合的弧面，该弧面有坡峰有谷底。当转动件的坡峰越过固定件的坡峰时，转动件在弹力作用下自动旋转到固定件的谷底，上、下离合部相互啮合，实现半自锁和半自动化。但是，限于结构形式，该转轴组件对加工要求非常高，两个相对转动的上、下离合部的相啮合表面加工难度高。最中心处设有连接轴，为铆接件，其成型难度比较大。固定件为一体件，制造难度偏大。
因此，有必要对现有转轴组件进行改进。
发明内容
本发明的一个目的是提供一种半自动转轴组件的新技术方案。
根据本发明的第一方面，提供了一种半自动转轴组件。该半自动转轴组件包括第一轴、弹性元件和套于所述第一轴上的套设件，所述第一轴与所述套设件转动连接；其中，在所述第一轴外周表面或套设件内周表面上设有沿周向延伸并呈环形的沟壑，所述沟壑在周向上为波形并且在轴向上具有波峰和波谷；在所述第一轴外周表面或套设件内周表面上设有与所述沟壑扣合的凸起，所述凸起被配置为在所述第一轴与所述套设件相对周向转动时，能沿所述沟壑的长度方向移动；所述弹性元件被配置在所述凸起越过所述沟壑的波峰之后，能将所述凸起推动至并且弹性限位在所述沟壑的波谷。
可选地，在所述沟壑的谷底位置设有对所述凸起进行限位的限位槽，所述凸起被配置为能在所述弹性元件的带动下移动至所述限位槽内、在带动所述第一轴与套设件相对转动的外力作用下离开所述限位槽并沿所述沟壑的长度方向移动。
可选地，所述沟壑在其宽度方向上具有弧形槽。
可选地，所述凸起朝向所述沟壑方向一侧的表面具有球面。
可选地，所述第一轴为转动轴，所述套设件固定设置。
可选地，在所述第一轴上设有用于带动所述第一轴转动的转动臂。
可选地，所述套设件包括位于所述第一轴周侧的多个支撑壁，多个所述支撑壁沿所述第一轴的周向间隔分布，至少在一个所述支撑壁上设有所述凸起。
可选地，还包括底座，所述套设件与所述底座之间可拆卸地安装在一起，所述弹性元件包括轴向压缩在所述底座与所述第一轴之间的弹簧。
可选地，所述底座包括与所述套设件可拆卸安装的底壁和自所述底壁向外突出的侧壁，所述第一轴的穿孔可转动地套于所述侧壁上，所述弹簧被轴向压缩在所述底座与侧壁之间。
可选地，所述弹簧被配置为在扣合所述凸起与所述沟壑时被轴向压缩。
本发明的发明人发现，在具备自锁及限位功能的转轴组件中，要么自锁功能一般，不具备半自动功能；要么具备半自动化和自锁功能，但加工难度高，导致半自动化功能不可靠。因此，本发明所要实现的技术任务或者所要解决的技术问题是本领域技术人员从未想到的或者没有预期到的，故本发明是一种新的技术方案。
根据本公开的一个实施例，在转动连接的第一轴与套设件上分别设有相扣合在一起的沟壑与凸起。其中，沟壑设于第一轴外周表面或套设件内周表面上并且沿周向延伸。沟壑在周向上为波形并且在轴向上具有波峰和波谷。在周向转动第一轴时，凸起能沿沟壑的长度方向移动，从而带动第一轴与套设件相对轴向移动。
在凸起越过沟壑的波峰之后，弹性元件带动凸起在无外力作用下自动移动至沟壑的波谷，实现对转轴组件的自锁、半自动化。
半自动转轴组件的结构简单、制造简单、体积利用率高。沟壑与凸起能可靠地扣合在一起，通过沟壑的曲线形设计配合弹性元件的弹力锁紧作用，实现转轴组件的自锁、半自动化，可靠性高。

在所述第一轴10外周表面或者所述套设件内周表面上设有与所述沟壑12扣合的凸起14。具体地，在将所述第一轴10与所述套设件套在一起后，所述凸起14穿入所述沟壑12内，所述沟壑12与所述凸起14扣合在一起。
例如图1所示，所述沟壑12设置于所述第一轴10的外周表面上。 所述凸起14设置于所述套设件的内周表面上。所述套设件内周表面上的凸起14与所述第一轴10外周表面上的沟壑12扣合在一起。

本公开中，所述第一轴10和所述套设件转动连接在一起，所述凸起14与所述沟壑12的扣合在一起。在所述第一轴10与所述套设件相对周向转动时，所述凸起14能沿所述沟壑12的长度方向移动。由于所述沟壑12为波形并且在轴向上具有波峰和波谷，当所述凸起14沿所述沟壑12的长度方向移动时，所述第一轴10和所述套设件相对轴向移动。
在所述凸起14越过所述沟壑12的波峰后，所述凸起14在所述弹性元件的弹力作用下能自动移动至并限位在所述沟壑12的谷底。实现了对转轴组件的自锁和半自动化。
所述半自动转轴组件的结构简单、制造简单、体积利用率高。所述沟壑12与所述凸起14能可靠地扣合在一起，通过所述沟壑12的波形设计配合所述弹性元件的弹力锁紧作用，实现对转轴组件的自锁、半自动化， 可靠性高。
需要说明的是，所述波峰和波谷分别是沟壑12在轴向上的两个极限位置。本公开中，所述凸起14能在所述弹性元件的弹力作用下自动进入所述波谷，所述波谷和波峰以此被区分。
在所述弹性元件的弹力作用下，所述凸起14还被限位在所述沟壑12的波谷。为了将所述凸起14更可靠地被所述弹性元件限位，可选地，参考图1、图2，在所述沟壑12的谷底位置设有用于对所述凸起14进行限位的限位槽13。所述凸起14越过波峰后，所述凸起14在所述弹性元件的带动下移动至所述限位槽13内。在所述弹性元件的弹性限位和所述限位槽13结构限位双重作用下，所述凸起14被限位在所述限位槽13内。所述凸起14在到达所述沟壑12谷底的过程中，不会因惯性、应力等产生来回晃动，甚至被撞击损坏。
在带动所述第一轴10与套设件相对转动的外力作用下，所述凸起14能离开所述限位槽13，进入所述沟壑12并沿所述沟壑12的长度方向继续移动。例如，所述限位槽13与所述沟壑12的谷底部分可连贯设置，以便于所述凸起14在外力作用下滑出所述限位槽13。
所述限位槽13的具体结构可以有多种。例如，所述限位槽13可以自所述沟壑12的谷底位置向轴向远离所述波峰的方向延伸的凹槽。
所述凸起14与所述沟壑12扣合在一起，而且所述凸起14能沿所述沟壑12的长度方向移动。可选地，参考图2、图3，所述沟壑12在其宽度方向上为弧形槽或者其他形状。例如，所述沟壑12在其宽度方向上可以为半圆形凹槽。
可选地，参考图1、图3，所述凸起14朝向所述沟壑12方向一侧的表面为球面。所述凸起14能可靠地沿所述沟壑12的长度方向滑动。
所述套设件套于所述第一轴10上，所述第一轴10与所述套设件转动连接。
一个实施例中，参考图2、图3，所述套设件固定设置，所述第一轴10在所述套设件内周向转动。在所述第一轴10周向转动时，在所述凸起 14与所述沟壑12的配合作用下，所述第一轴10相对于所述套设件轴向移动。
本实施例中，参考图1、图2，在所述第一轴10上可设有用于带动所述第一轴10转动的转动臂18。在旋转所述转动臂18时，所述第一轴10能同步转动。例如，所述转动臂18可以固定安装于所述第一轴10的轴向一端的表面上。例如，所述转动臂18可通过第二螺钉19等紧固件安装于所述第一轴10上。
本实施例中，参考图1、图2，所述套设件可以包括位于所述第一轴10周侧的多个支撑壁11。多个所述支撑壁11沿所述第一轴10的周向间隔分布。至少在一个所述支撑壁11上设有所述凸起14。例如图3所示，所述支撑壁11的数量可以为两个，两个所述支撑壁11相对地设置于所述第一轴10的周侧。
本实施例中，所述套设件固定设置的方式有多种。参考图1、图2，所述转轴组件还可以包括底座16。所述套设件与所述底座16之间可拆卸地安装在一起。所述弹性元件包括轴向压缩在所述底座16与所述第一轴10之间的弹簧15。所述底座16与所述第一轴10之间具有用于收纳所述弹簧15的放置空间。定义所述第一轴10朝向所述底座16的方向为下，反之为上。
在所述凸起14越过所述沟壑12的波峰之后，在所述弹簧15弹力的带动下，所述凸起14移动至并且弹性限位在所述波谷或者限位槽13内。
所述底座16的具体结构可以有多种。可选地，参考图3，在所述第一轴10的底部设有第一孔100。所述底座16包括底壁160和自所述底壁160向外突出的侧壁161。所述套设件与所述底壁160可拆卸地安装在一起。例如，所述套设件与所述底壁160可通过第一螺钉17固定安装在一起。所述第一轴10通过第一孔100可转动地套于所述侧壁161上，所述弹簧15被轴向压缩在所述底座16与侧壁161之间。例如，在所述侧壁161可以设有与所述第一孔100相对的第二孔162，所述弹簧15被轴向压缩在所述第一孔100与第二孔162之间。
在所述凸起14被移动至所述波谷或者限位槽13之后，所述弹簧15还能施加将所述凸起14弹性限位在所述波谷或者限位槽13内的弹力。参考图3，在扣合所述凸起14与所述沟壑12时，所述弹簧15始终处于被轴向压缩的状态。例如，装配转轴组件时，在将所述第一轴10套在所述底座16的侧壁161上之后，可用夹具按压并夹持所述第一轴10或转动臂18的顶面和所述底座16的底面，以使所述弹簧15被周向压缩，便于将所述凸起14与所述沟壑12扣合。
一个具体实施方式中，参考图1至图3，首先，将第一轴10与转动臂18固定安装。将弹簧15放入底座16的第一孔100或者侧壁161的第二孔162内。然后，将第一轴10套在底座16的侧壁161上。再用夹具按压并夹持转动臂18的顶面和底座16的底面，弹簧15被压缩并保持。之后，将多个支撑壁11与底座16的底壁160固定安装，使得凸起14与沟壑12扣合在一起。
另一实施例中，所述第一轴可被固定设置。所述套设件套于所述第一轴上并且能相对于所述第一轴周向转动。该实施例中，所述套设件为转动轴。例如，所述套设件可以是套于所述第一轴上的套筒。
该实施例中，所述转轴组件的具体结构可以与上一实施例同理设置，在此不作赘述。
虽然已经通过例子对本发明的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上例子仅是为了进行说明，而不是为了限制本发明的范围。本领域的技术人员应该理解，可在不脱离本发明的范围和精神的情况下，对以上实施例进行修改。本发明的范围由所附权利要求来限定。
