Description

固定销的安装工具及安装方法 技术领域
本发明涉及发动机装配领域，尤其涉及一种固定销的安装工具及安装方法。
背景技术
高压涡轮转子是航空发动机的重要组成部分，作为转动部件，安装到发动机上之前要进行动平衡。加配重就是消除转子不平衡量的一种重要措施。图1是一种高压涡轮转子的结构示意图。参考图1所示，配重块30通过固定销20固定在法兰边上。由于该固定销20体积较小，属于微型件，因而难以固定，手工安装时难度较大。
现有的装配模式一般是采用镊子夹取固定销20，对齐安装孔(图中未标示)后，通过手锤将固定销20敲入安装孔。然而，固定销20安装的附近区域形面较为复杂。例如，涡轮盘10的内外两侧均有较为复杂的异形凹槽(即凹槽11和凹槽12)。若采用镊子夹持的方式，固定销20容易脱落，从而掉入内外两侧的凹槽中。由于固定销20过于微小，加上凹槽为非规则的异形复杂形面，一旦固定销20掉入两侧的凹槽中，很难找到并从凹槽内取出固定销20。
发明内容
本发明所要解决的技术问题是提供一种固定销的安装工具，该安装工具可以减小固定销的掉落风险，增加装配的安全性，降低了安装难度，提高了装配效率，结构简单、易于操作且成本较低。

本发明的较佳实施方式
为让本发明的上述目的、特征和优点能更明显易懂，以下结合附图对本发明的具体实施方式作详细说明。
在下面的描述中阐述了很多具体细节以便于充分理解本发明，但是本发明还可以采用其它不同于在此描述的其它方式来实施，因此本发明不受下面公开的具体实施例的限制。
如本申请和权利要求书中所示，除非上下文明确提示例外情形，“一”、“一个”、“一种”和/或“该”等词并非特指单数，也可包括复数。一般说来，术语“包括”与“包含”仅提示包括已明确标识的步骤和元素，而这些步骤和元素不构成一个排它性的罗列，方法或者设备也可能包含其他的步骤或元素。
在详述本发明实施例时，为便于说明，表示器件结构的剖面图会不依一般比例作局部放大，而且所述示意图只是示例，其在此不应限制本发明保护的范围。此外，在实际制作中应包含长度、宽度及深度的三维空间尺寸。
为了方便描述，此处可能使用诸如“之下”、“下方”、“低于”、“下面”、“上方”、“上”等等的空间关系词语来描述附图中所示的一个元件或特征与其他元件或特征的关系。将理解到，这些空间关系词语意图包含使用中或操作中的器件的、除了附图中描绘的方向之外的其他方向。例如，如果翻转附图中的器件，则被描述为在其他元件或特征“下方”或“之下”或“下面”的元件的方向将改为在所述其他元件或特征的“上方”。因而，示例性的词语 “下方”和“下面”能够包含上和下两个方向。器件也可能具有其他朝向(旋转90度或处于其他方向)，因此应相应地解释此处使用的空间关系描述词。此外，还将理解，当一层被称为在两层“之间”时，它可以是所述两层之间仅有的层，或者也可以存在一个或多个介于其间的层。
在本申请的上下文中，所描述的第一特征在第二特征之“上”的结构可以包括第一和第二特征形成为直接接触的实施例，也可以包括另外的特征形成在第一和第二特征之间的实施例，这样第一和第二特征可能不是直接接触。
应当理解，当一个部件被称为“在另一个部件上”、“连接到另一个部件”、“耦合于另一个部件”或“接触另一个部件”时，它可以直接在该另一个部件之上、连接于或耦合于、或接触该另一个部件，或者可以存在插入部件。相比之下，当一个部件被称为“直接在另一个部件上”、“直接连接于”、“直接耦合于”或“直接接触”另一个部件时，不存在插入部件。
本发明的以下实施例提出一种固定销的安装工具，该安装工具可以减小固定销的掉落风险，增加装配的安全性，降低了安装难度，提高了装配效率，结构简单、易于操作且成本较低。
图2是本发明一实施例的一种固定销的安装工具的示意图。图3是本发明一实施例的一种固定销的安装工具的剖面示意图。其中，图3显示的是沿图2所示的虚线作为剖面线的剖面示意图。
下面结合图2和图3对该固定销的安装工具进行说明。可以理解的是，下面所进行的描述仅仅示例性的，本领域技术人员可以在不脱离本发明的精神的情况下，进行各种变化。
参考图2和图3所示，该固定销的安装工具100包括管体110、压销120以及驱动螺母140。
管体110内设有腔室111，腔室111适于容纳多个固定销20，管体110的表面具有相对设置且与腔室111连通的第一滑槽112和第二滑槽(图未示)。管体110的两端分别设有连通腔室111的第一开口113和第二开口114，多个固定销20适于通过第一开口113进入腔室111且适于通过第二开口114退出腔室111。
可以理解，腔室111的内径应当与固定销20的直径相匹配。优选的，在 本发明的以下实施例中，腔室111的内径等于固定销20的直径。
在一些实施例中，腔室111的内壁还可以为弹性材质，腔室111的内径则可以略小于固定销20的直径，从而保证多个固定销20在未受外部推力的情况下，无法在腔室111内移动。
第一滑槽112和第二滑槽可以在管体110表面沿着管体110的延伸方向而分布。
优选的，在图2和图3所示的一些实施例中，管体110的外形为圆柱状。第一滑槽112的中心线与第二滑槽的中心线以及管体110的中心线共面，但本发明并非以此为限。
压销120穿过第一滑槽112和第二滑槽而可移动地设于管体110上，压销120的至少一部分露出管体110的表面。第一滑槽112和第二滑槽可以在压销120的移动过程中起到引导的作用。
在一些示例中，压销120可以只有一端露出管体110的表面。在另一些示例中，压销120的两端可以同时露出管体110的表面，本领域技术人员可以根据实际需要做出相应的调整，本发明并非以此为限。
驱动螺母140连接管体110，且适于驱动压销120朝第二开口114的方向移动。
示例性的，可以将压销120穿过第一滑槽112和第二滑槽，并移至多个固定销20中最靠近第一开口113的固定销的靠近第一开口113的端面上。这样，在压销120受驱动螺母140驱动而朝第二开口114的方向移动的过程中，会推动腔室111内的多个固定销20朝第二开口114的方向移动。
在本发明的一实施例中，管体110的表面设有外螺纹(图未示)，驱动螺母140设有内螺纹(图未示)，驱动螺母140与管体110螺接。这样，当转动驱动螺母140时，驱动螺母140在管体110的表面通过螺纹副的方式进行移动，进而可以驱动压销120朝第二开口114的方向移动。
优选的，管体110表面的外螺纹分布可以使驱动螺母140在管体110表面朝第二开口114的方向移动至极限位置时，压销120可以将腔室111内的全部多个固定销20推出腔室111外。
在本发明的一实施例中，安装工具100还包括位于压销120和驱动螺母140 之间的压盖130，压盖130穿设于管体110的表面，驱动螺母140通过压盖130驱动压销120朝第二开口114的方向移动。
在图2所示的一个示例中，压盖130上位于压销120的一侧设有与压销120对应的固定槽131。压销120可以在朝第二开口114的方向移动的过程中固定于压盖130的固定槽131中。
参考图3所示，在本发明的一个优化例中，压销120的两端同时露出管体110的表面，且压销120的直径与压盖130的直径相匹配(例如相同)。这样，在驱动螺母140通过压盖130驱动压销120朝第二开口114的方向移动的过程中，压销120的两端可以保持良好的平衡。
在本发明的一实施例中，固定销20的直径可以小于等于2mm。在一些实施例中，固定销的高度可以小于等于4mm。
参考图1所示，在本发明的一实施例中，固定销20可以用于固定涡轮转子的配重块30。
图4是本发明一实施例的一种固定销的安装工具的收敛部的剖面示意图。参考图2至图4所示，在本发明的一实施例中，管体110还包括收敛部115。其中，位于收敛部115内的至少一部分腔室111的内径小于固定销20的直径。
示例性的，可以仅有部分位于收敛部115内的腔室111的内径小于固定销20的直径；也可以全部位于收敛部115内的腔室111的内径均小于固定销20的直径。
通过使位于收敛部115内的至少一部分腔室111的内径小于固定销20的直径，可以保证多个固定销20在未受外部推力的情况下，无法经第二开口114退出腔室111。
继续参考图2所示，在本发明的一实施例中，收敛部115的表面可以设有多个条形槽115a。多个条形槽115a可以将收敛部115分隔为多个瓣状结构，从而使得收敛部115具有一定的弹性。
在一些示例中，收敛部115还可以为弹性材质。
这样，在腔室111内的多个固定销20受到外部推力(例如来自压销120的推动)而朝第二开口114的方向移动的过程中，位于收敛部115内的至少一部分腔室111的内径受到挤压力的作用而相应地变大，从而使得多个固定销20 可以经第二开口114依次退出腔室111。
在本发明的以上实施例中，收敛部115是管体110的一部分。在本发明的另一些实施例中，收敛部115还可以是一个独立的部件。收敛部115可以通过包括螺接在内的多种连接方式与管体110固定连接，本发明并非以此为限。
本领域技术人员可以根据实际需要对收敛部115的具体尺寸(例如长度)做出相应的调整，本发明并非以此为限。
本发明的固定销的安装工具100通过将多个固定销20装入管体110的腔室111内，可以有效避免在安装过程中固定销20掉落至涡轮盘10内外两侧的异形凹槽(例如凹槽11和凹槽12)中，增加了装配的安全性。
此外，通过设置合适的腔室111容量，使该安装工具100可以同时容纳多个固定销20，减少了分次拿取固定销20所花费的时间，缩短了安装周期，提高了装配效率。
另一方面，本发明通过将微型的固定销20放大为可手持操作的固定销的安装工具100，降低了安装的难度。该固定销的安装工具100结构简单、易于操作且成本较低。
本发明的以上实施例提出了一种固定销的安装工具，该安装工具可以减小固定销的掉落风险，增加装配的安全性，降低了安装难度，提高了装配效率，结构简单、易于操作且成本较低。
本发明的另一方面提出一种固定销的安装方法，该安装方法可以减小固定销的掉落风险，增加装配的安全性，降低了安装难度，提高了装配效率，易于操作且成本较低。
该固定销的安装方法包括以下步骤：a.通过第一开口将多个固定销装入管体的腔室内；b.将压销穿过第一滑槽和第二滑槽；c.转动驱动螺母，以驱动压销朝第二开口的方向移动，直至多个固定销中最靠近第二开口的固定销的一部分通过第二开口退出腔室；d.将最靠近第二开口的固定销对准安装孔，继续转动驱动螺母，直至最靠近第二开口的固定销完全退出腔室并进入安装孔内；e.重复步骤c到d，直至完成多个固定销的安装。
图5是本发明一实施例的一种固定销的安装方法的流程图。图6是本发明一实施例的一种固定销的安装方法的示意图。
下面结合图5和图6对该安装方法进行说明。可以理解的是，下面所进行的描述仅仅示例性的，本领域技术人员可以在不脱离本发明的精神的情况下，进行各种变化。
应当注意，该安装方法可以通过例如图2至图4所示的固定销的安装工具100或其变化例来实施，但本发明并非以此为限。
参考图5所示，该安装方法包括以下步骤：
步骤a，通过第一开口113将多个固定销20装入管体110的腔室111内。
示例性的，可以通过第一开口113将多个固定销20首尾相连地装入管体110的腔室111内。
参考图2所示，在本发明的一实施例中，安装工具100还包括位于压销120和驱动螺母140之间的压盖130，压盖130穿设于管体110的表面，驱动螺母140通过压盖130驱动压销120朝第二开口114的方向移动。
在本发明的一实施例中，固定销20的直径可以小于等于2mm。在一些实施例中，固定销的高度可以小于等于4mm。
参考图1所示，在本发明的一实施例中，固定销20可以用于固定涡轮转子的配重块30。
可选地，步骤a之前还可以包括将压销120从管体110上取下。
可选地，步骤a之前还可以包括将压销120、压盖130以及驱动螺母140分别从管体110上取下，但本申请的实施例并非以此为限。
步骤b，将压销120穿过第一滑槽112和第二滑槽(图未示)。
将压销120穿过第一滑槽112和第二滑槽，并移至多个固定销20中最靠近第一开口113的固定销的靠近第一开口113的端面上。压销120的至少一部分露出管体110的表面。第一滑槽112和第二滑槽可以在压销120的移动过程中起到引导的作用。
在一些示例中，压销120可以只有一端露出管体110的表面。在另一些示例中，压销120的两端可以同时露出管体110的表面，本领域技术人员可以根据实际需要做出相应的调整，本发明并非以此为限。
参考图3所示，在本发明的一个优化例中，压销120的两端同时露出管体110的表面，且压销120的直径与压盖130的直径相匹配(例如相同)。这样， 在驱动螺母140通过压盖130驱动压销120朝第二开口114的方向移动的过程中，压销120的两端可以保持良好的平衡。
可选地，步骤b之后还可以包括将压盖130和驱动螺母140分别安装在管体110上。
在图2所示的一个示例中，压盖130上位于压销120的一侧设有与压销120对应的固定槽131。压销120可以在朝第二开口114的方向移动的过程中固定于压盖130的固定槽131中。
步骤c，转动驱动螺母140，以驱动压销120朝第二开口114的方向移动，直至多个固定销20中最靠近第二开口114的固定销的一部分通过第二开口114退出腔室111。
在本发明的一实施例中，管体110的表面设有外螺纹(图未示)，驱动螺母140设有内螺纹(图未示)，驱动螺母140与管体110螺接。这样，当转动驱动螺母140时，驱动螺母140在管体110的表面通过螺纹副的方式进行移动，进而可以驱动压销120朝第二开口114的方向移动。
参考图2至图4所示，在本发明的一实施例中，管体110还包括收敛部115。其中，位于收敛部115内的至少一部分腔室111的内径小于固定销20的直径。
示例性的，可以仅有部分位于收敛部115内的腔室111的内径小于固定销20的直径；也可以全部位于收敛部115内的腔室111的内径均小于固定销20的直径。
通过使位于收敛部115内的至少一部分腔室111的内径小于固定销20的直径，可以保证多个固定销20在未受外部推力的情况下，无法经第二开口114退出腔室111。
继续参考图2所示，在本发明的一实施例中，收敛部115的表面可以设有多个条形槽115a。多个条形槽115a可以将收敛部115分隔为多个瓣状结构，从而使得收敛部115具有一定的弹性。
在一些示例中，收敛部115还可以为弹性材质。
这样，在腔室111内的多个固定销20受到外部推力(例如来自压销120的推动)而朝第二开口114的方向移动的过程中，位于收敛部115内的至少一部分腔室111的内径受到挤压力的作用而相应地变大，从而使得多个固定销20 可以经第二开口114依次退出腔室111。
在本发明的以上实施例中，收敛部115是管体110的一部分。在本发明的另一些实施例中，收敛部115还可以是一个独立的部件。收敛部115可以通过包括螺接在内的多种连接方式与管体110固定连接，本发明并非以此为限。
本领域技术人员可以根据实际需要对收敛部115的具体尺寸(例如长度)做出相应的调整，本发明并非以此为限。
优选的，在此步骤中，最靠近第二开口114的固定销退出腔室111的部分可以小于或等于单个固定销20的高度的一半，但本发明并非以此为限。
步骤d，将最靠近第二开口114的固定销对准安装孔31，继续转动驱动螺母140，直至最靠近第二开口114的固定销完全退出腔室111并进入安装孔31内。
参考图6所示，可以将安装工具100移至需要固定的涡轮转子的配重块30的上方，并将最靠近第二开口114的固定销对准相应的安装孔31。然后，继续转动驱动螺母140，直至最靠近第二开口114的固定销完全退出腔室111并进入安装孔31内。
步骤e，重复步骤c到步骤d，直至完成多个固定销20的安装。
经过以上步骤，可以将腔室111内的全部多个固定销20分别安装到对应的安装孔31内。
本发明的固定销的安装方法通过将多个固定销20装入安装工具100的管体110的腔室111内，可以有效避免在安装过程中固定销20掉落至涡轮盘10内外两侧的异形凹槽(例如凹槽11和凹槽12)中，增加了装配的安全性。
此外，通过设置合适的腔室111容量，使该安装工具100可以同时容纳多个固定销20，减少了分次拿取固定销20所花费的时间，缩短了安装周期，提高了装配效率。
另一方面，本发明通过将微型的固定销20放大为可手持操作的固定销的安装工具100，降低了安装的难度。该安装方法易于操作且成本较低。
应当注意，在此使用了图5所示的流程图来说明根据本申请的实施例的安装方法所执行的步骤/操作。可以理解的是，这些步骤/操作不一定按照顺序来精确地执行。相反，可以按照倒序或同时处理各种步骤/操作。同时，或将其他 步骤/操作添加到这些过程中，或从这些过程移除某一步或数步步骤/操作。
本实施例的安装方法的其他实施细节可参考图2至图4所描述的实施例，在此不再展开。本领域技术人员可以根据实际需要对该安装方法的具体操作步骤的优先顺序做出适当的调整，本发明并非以此为限。
本发明的以上实施例提出了一种固定销的安装方法，该安装方法可以减小固定销的掉落风险，增加装配的安全性，降低了安装难度，提高了装配效率，易于操作且成本较低。
可以理解，尽管上述披露中通过各种示例讨论了一些目前认为有用的发明实施例，但应当理解的是，该类细节仅起到说明的目的，附加的权利要求并不仅限于披露的实施例，相反，权利要求旨在覆盖所有符合本申请实施例实质和范围的修正和等价的任意组合。
上文已对基本概念做了描述，显然，对于本领域技术人员来说，上述发明披露仅仅作为示例，而并不构成对本申请的限定。虽然此处并没有明确说明，本领域技术人员可能会对本申请进行各种修改、改进和修正。该类修改、改进和修正在本申请中被建议，所以该类修改、改进、修正仍属于本申请示范实施例的精神和范围。
同时，本申请使用了特定词语来描述本申请的实施例。如“一个实施例”、“一实施例”、和/或“一些实施例”意指与本申请至少一个实施例相关的某一特征、结构或特点。因此，应强调并注意的是，本说明书中在不同位置两次或多次提及的“一实施例”或“一个实施例”或“一替代性实施例”并不一定是指同一实施例。此外，本申请的一个或多个实施例中的某些特征、结构或特点可以进行适当的组合。
此外，除非权利要求中明确说明，本申请所述处理元素和序列的顺序、数字字母的使用、或其他名称的使用，并非适于限定本申请流程和方法的顺序。尽管上述披露中通过各种示例讨论了一些目前认为有用的发明实施例，但应当理解的是，该类细节仅起到说明的目的，附加的权利要求并不仅限于披露的实施例，相反，权利要求旨在覆盖所有符合本申请实施例实质和范围的修正和等价组合。例如，虽然以上所描述的系统组件可以通过硬件设备实现，但是也可以只通过软件的解决方案得以实现，如在现有的服务器或移动设备上安装所描 述的系统。
同理，应当注意的是，为了简化本申请披露的表述，从而帮助对一个或多个申请实施例的理解，前文对本申请实施例的描述中，有时会将多种特征归并至一个实施例、附图或对其的描述中。但是，这种披露方法并不意味着本申请对象所需要的特征比权利要求中提及的特征多。实际上，实施例的特征要少于上述披露的单个实施例的全部特征。
一些实施例中使用了描述成分、属性数量的数字，应当理解的是，此类适于实施例描述的数字，在一些示例中使用了修饰词“大约”、“近似”或“大体上”来修饰。除非另外说明，“大约”、“近似”或“大体上”表明所述数字允许有±20％的变化。相应地，在一些实施例中，说明书和权利要求中使用的数值参数均为近似值，该近似值根据个别实施例所需特点可以发生改变。在一些实施例中，数值参数应考虑规定的有效数位并采用一般位数保留的方法。尽管本申请一些实施例中适于确认其范围广度的数值域和参数为近似值，在具体实施例中，此类数值的设定在可行范围内尽可能精确。
虽然本发明已参照当前的具体实施例来描述，但是本技术领域中的普通技术人员应当认识到，以上的实施例仅是用来说明本发明，在没有脱离本发明精神的情况下还可作出各种等效的变化或替换，因此，只要在本发明的实质精神范围内对上述实施例的变化、变型都将落在本申请的权利要求书的范围内。
