Description

一种穿刺针的装配治具 技术领域
本发明涉及穿刺针组装技术领域，特别地涉及一种穿刺针的装配治具。
背景技术
穿刺针包括内针和外针，内针穿设于外针的内部，在内针和外针的顶端设置斜切口形成针尖结构，其中，穿刺针使用时需要保证内针的针尖和外针的针尖对齐，即两者的斜切口形成的切面角度相同。外针底部连接外针底座，内针的底部连接内针底座，内针底座和外针底座之间设有限位结构，限位结构可避免内针与外针相对转动，保持针尖对齐。
穿刺针装配时，将外针与外针底座固定连接，将内针放置在内针底座的欲安装位置，之后，将外针套设在内针上，此时，内针底座与外针底座和外针底座之间在限位结构的作用下无法相对转动，但是，由于内针与内针底座之间为非安装状态，内针可自由旋转，通过旋转内针调整针尖角度，使其与外针的针尖对齐，最后，保持内针的角度不便，拔出外针，向内针的底部滴胶，使内针与内针底座固定连接。
但是，现有技术中手动的调整转动内针，导致穿刺针的装配时间较长，工作效率较低，且装配操作步骤复杂；同时，由于手动的操作，在进行滴胶操作时，极易造成内针旋转的误操作，报废率较高，造成生产成本提高。
发明内容
有鉴于此，本发明提供一种穿刺针的装配治具，以达到穿刺针装配操作简单、快速，且成品率高的目的。
为实现上述目的，根据本发明提供了一种穿刺针的装配治具，包括底座和旋转架，所述底座的上表面为操作平面，所述旋转架设于所述操作平面上，并能以竖立在所述操作平面上的轴为旋转中心，在所述操作平面上水平转动；所述旋转中心处还设有竖立在所述旋转架表面的柱形的内针插槽，柱形的内针插槽的轴线重合于所述旋转中心，并且轴线处具有轴向的孔，从而内针底座能够套在所述内针插槽上，并且在装配所述穿刺针的内针时，该内针能够插入所述孔。

具体实施方式
以下结合附图对本发明的示范性实施例做出说明，其中包括本发明实施例的各种细节以助于理解，应当将它们认为仅仅是示范性的。因此，本领域普通技术人员应当认识到，可以对这里描述的实施例做出各种改变和修改，而不会背离本发明的范围和精神。同样，为了清楚和简明，以下的描述中省略了对公知功能和结构的描述。
如图1-6所示，一种穿刺针的装配治具，包括底座1和旋转架2，底座1的上表面为操作平面11，旋转架2设于操作平面11上，并能以竖立在操作平面11上的轴12为旋转中心，在操作平面11上水平转动；旋转中心处还设有竖立在旋转架2表面的柱形的内针插槽，柱形的内针插槽的轴线重合于旋转中心，并且轴线处具有轴向的孔，从而内针底座1能够套在内针插槽上，并且在装配穿刺针的内针时，该内针能够插入孔。优选地，底座1呈圆柱形，其顶部为圆形的操作平面11，旋转中 心与操作平面11的圆心重合。
本实施例提供的装配治具，利用旋转架2调整内针的针尖角度，旋转架2对内针起到固定及调节的作用，区别于现有技术中手动调节的方式，其优点在于，利用旋转架2调整，将内针进行固定后便无需再对内针施加操作，简单地在操作平面11上转动旋转架2即可调节内针的针尖角度，操作简单快捷，可实对现内针的快速调节，提高装配的工作效率；内针角度调节完成后，取下外针，进行滴胶操作时，由于非手动地调整内针，此过程内针仍被固定在内针插槽中，不会产生位置的偏离，进而不会出现误操作的现象，提高产品的成品率。
作为本实施例的优选实施方式，内针插槽沿垂直操作平面11方向剖分为截面为相向的弧形的固定半槽21和移动半槽31，从而固定半槽21和移动半槽31互相贴合时在二者之间形成孔，固定半槽21与旋转架2垂直固定连接，移动半槽31与夹紧盖板3垂直固定连接；旋转架2上设有滑槽22，夹紧盖板3设于滑槽22内，夹紧盖板3于滑槽22内滑动带动移动半槽31移动，使移动半槽31与固定半槽21的对接或分离。
为了方便内针与内针插槽的拆装，将内针插槽设置为分体结构。内针与内针插槽连接时，先使固定半槽21和移动半槽31分离，内针安装到位后，推动夹紧盖板3移动，使固定半槽21和移动半槽31对接，内针的底部被固定在对接成形的孔中，此时，可转动旋转架2调整内针的针尖角度。优选地，夹紧盖板3远离移动半槽31的一端垂直设有推动把手32，在操作移动半槽31与固定半槽21的分离或对接时，可手动的搬动推动把手32来调节。推动把手32和夹紧盖板3为一体结构，且材质为金属。装配操作过程中，操作控制最多的部件是夹紧盖板3，因此，将其设置为金属结构，具有更高的强度，使用寿命更长。
作为本实施例的优选实施方式，旋转架2上位于夹紧盖板3远离移 动半槽31的一端设有夹紧组件，夹紧组件推动夹紧盖板3在滑槽22内滑动，使夹紧盖板3上的移动半槽31与固定半槽21保持对接状态。优选地，夹紧组件包括压紧块4和夹紧按钮5，压紧块4和夹紧按钮5分别与旋转架2转动连接，压紧块4与夹紧按钮5通过连接杆6连接；压紧块4上设有用于按压夹紧盖板3的压头，压头推动夹紧盖板3在滑槽22内滑动。
为了提高移动半槽31和固定半槽21对接连接的稳定性，在夹紧盖板3远离移动半槽31的一端设置夹紧组件，夹紧组件对夹紧盖板3施加压力，确保移动半槽31与固定半槽21之间对接稳定，即保证夹紧内针。具体地操作为，需要取下内针时，手动的搬动夹紧按钮5，夹紧按钮5转动通过连接杆6带动压紧块4转动，压紧块4上的压头与推动把手32分离，此时，可手动的搬动推动把手32，使夹紧盖板3移动，移动半槽31与固定半槽21分离，可取下内针；当需要夹紧内针时，将内针底部放置在固定半槽21中，手动的反向搬动夹紧按钮5，带动压紧块4的压头转动，压头推动夹紧盖板3移动，夹紧按钮5与旋转架2扣合，同时完成压头对夹紧盖板3的顶紧。
作为本实施例的优选实施方式，还包括用于支撑和限位内针底座1的支撑结构7；支撑结构7包括两块平行设置的支撑板71，两块支撑板71垂直操作平面11设置，且两块支撑板71之间设有限定宽度的间隔，间隔的中心与内针插槽的轴线重合；两块支撑板71的一侧端通过支架72与操作平面11固定连接。
支撑结构7的作用是用于固定内针底座1，在进行装配时，将内针底座1卡接在两块支撑板71之间。此操作方式的优点在于，减少人为的手动操作，可更加灵活的进行点胶地操作步骤，另外，可降低由于人为因素(如晃动等)导致的装配出现偏差，进一步提高产品的成品率。
作为本实施例的优选实施方式，旋转架2上设有限位槽；操作平面 11上竖立的轴12插接在限位槽内，旋转架2通过轴12和限位槽的配合在操作平面11上水平转动。旋转架2在操作平面11上转动，其中，在旋转架2上设置一限位槽结构，与操作平面11上的轴12连接便可实现旋转架2的圆周转动，此结构简单，生产制造工艺简便。
作为本实施例的优选实施方式，操作平面11上垂直设有立柱，立柱远离操作平面11的一端设有用于限位外针的外针挡板8，外针挡板8与操作平面11平行设置。外针挡板8对外针其限位作用，即在进行装配时，外针需要于外针挡板8指定的位置相贴合，若外针未在指定位置，则表示为外针位置偏离需要进行调整，通过设置外针挡板8，可进一步地提高装配的工作效率，以及装配产品的成本品率。
本实施例提供的一种穿刺针的装配治具，在进行装配操作时，首先，将底座1放置在一平台上，压紧块4和压紧按钮呈开启状态。将内针底座1卡接在支撑板71之间进行固定，之后，将内针放置在固定半槽21中，按压压紧按钮，使压紧块4转动扣合，压紧块4的压头推动夹紧盖板3在旋转架2的滑槽22内滑动，带动移动半槽31与固定半槽21对接，从而将内针固定。
内针和内针底座1均被固定后，将外针套设在内针上，通过外针挡板8对外针进行限位，内针外针安装到装配治具上后，转动旋转架2，旋转架2带动内针转动，观察内针的针尖角度，待转动至内针针尖角度与外针针尖角度一致后，停止转动旋转架2，此时，可用一只手对旋转架2进行固定，或者，利用辅助的限位结构对旋转架2进行固定，如限位卡扣，限位塞等。之后，取下外针，向内针与内针底座1之间的间隙内滴胶，实现内针与外针的装配。
该穿刺针的装配治具，装配过程中，对内针角度的调节简单快捷，可大大提高装配的工作效率，而且，内针通过内针凹槽进行固定，更加牢固稳定，不易出现误操作导致的产品报废的状况，成品率提高，降低 生产制造成本。
上述具体实施方式，并不构成对本发明保护范围的限制。本领域技术人员应该明白的是，取决于设计要求和其他因素，可以发生各种各样的修改、组合、子组合和替代。任何在本发明的精神和原则之内所作的修改、等同替换和改进等，均应包含在本发明保护范围之内。
