Description

一种用于转台框架同轴度检测的装置 技术领域
本发明涉及一种用于转台框架同轴度检测的装置，属于精密装配工艺工装领域。
背景技术
转台框架为薄壁腔型结构，主要有“O”和“U”两种结构形式。转台轴孔同轴度和轴孔端面垂直度、平行度，都是转台框架的重要精度指标，其精度直接影响着转台的精度和稳定性。由于转台框架结构的特殊性和较高的精度要求，现有机床的加工的转台框架精度很难满足设计要求，而目前一些通用的检测方法也并不适用于转台框架的精度检测。虽然三坐标测量仪能够满足一部分小尺寸转台框架的精度检测要求，比如轴孔同轴度的检测，但三坐标测量仪存在以下局限性：(1)对尺寸较大的转台框架，三坐标测量仪测量范围和精度不能满足要求；(2)三坐标测量仪测量环境要求高于转台框架的装配环境要求，因此不能完全真实反应检测数据；(3)转台的框架较多，三坐标测量仪检测工作量较大，不能满足转台产业化发展的需求；(4)使用三坐标测量仪，工作量大，效率低，不便于实时检测转台框架修配后的精度；(5)三坐标测量仪需专业使用和维护，使用成本较高。
鉴于以上原因，现有技术缺乏在转台装配环境中有效、便利地测量转台轴孔同轴度的检测工具。特别的，在转台的装配过程中，为了达到较高的精度要求，往往需要对转台框架的配合端面进行修配，修配量的合理与否直接影响转台轴系的回转精度，但由于现有技术的缺陷，装配工人无法随时对转台框架的轴孔和端面进行检测，无法知晓具体修配量，修配量完全取决于装配人员的经验，一方面对操作人员要求非常高，另一方面也导致需要经过多次试凑、反复修配才能达到轴系回转精度，且在多次调修的过程中，容易造成轴系精度不稳 定和对高精度轴承等成件的损坏、零件报废等问题。为了保证装配精度，提高装配效率，降低装配成本，有必要研制有效的转台框架检测装置，可以快速、便利地在转台装配环境中测量转台框架的同轴度等精度指标。

如图1、图2、图3所示，滑动V型块4和V型块5方向平行，滑动V型块4和V型块5上的每个斜面上均固定联接有一个圆棒8，该圆棒采用黄铜制成，可称为铜棒8。滑动V型块4、V型块5各通过两个螺钉(图3中用虚线表示)固定连接在滑块组件3的两端。滑动V型块4与螺钉配合的孔为腰型孔(图3中用虚线表示)；松动螺钉，可调节滑动V型块4在滑块组件3上的位置，滑动V型块4的滑动方向与滑块组件3的平行移动方向相互垂直，锁紧螺钉，可固定滑动V型块4在滑块组件3上的位置。
如图1、图2、图6所示，心轴组件6放置在滑动V型块和V型块上的铜棒8上。心轴组件6的轴线方向垂直于滑块组件3的平行移动方向。心轴组件6由心轴和两个安装盘组成，心轴上拧有4个螺钉以方便用手使心轴组件6在铜棒8上沿心轴轴线转动。安装盘中心有顶尖孔，以方便心轴组件6进行精磨。两个安装盘用螺钉组装在心轴上，心轴和两个安装盘用高精度外圆磨床精磨，保证心轴外圆的圆柱度0.005mm以内，粗糙度在Ra0.4以内，两个安装盘的平行度在0.005mm以内。
如图1所示，心轴组件的两端各安装有一个支架组件7。每个支架组件7上均安装有表架16，每个表架16上均安装有千分表17。每个支架组件7均由法兰座和调整杆组成，法兰座与心轴组件上的安装盘固定联接。调整杆嵌入法兰座，并能够沿法兰座的轴向方向移动，即调整杆可在法兰座中伸缩，法兰座上有多个螺纹孔，通过螺钉可调节调整杆在法兰座中的伸出长度，从而调节表架16、千分表17与心轴组件6的相对位置，以满足不同尺寸的转台框架的检测要求。调整杆端部设有螺纹孔，能够通过安装螺钉穿过所述调整杆端部的螺纹孔，用来调节固定表架16在调整杆中的尺寸，调整范围在50～350mm，从而能实现对不同尺寸转台框架轴孔的同轴度检测。千分表17通过螺钉固定在表架16上，并可通过螺钉调节千分表17的俯仰角度，在检测时可实现局部微调。
如图1、图2、图3、图7所示，安装座9、螺杆10、L板11、法兰盘12、把手13和转柄14组成检测装置的驱动部分。安装座9通过螺钉固定联接在滑块组件3中的上滑块上，L板11通过螺钉固定联接在导轨组件2上，螺杆安装在安装座9和L板11之间，通过螺母固定联接在安装座9上。法兰盘12与L板11固定联接，转柄14具有凸缘，凸缘嵌入法兰盘12内，法兰盘12内均匀抹润滑脂，转柄14可在法兰盘12中灵活转动。转柄14上设计有螺纹孔，通过螺纹连接在螺杆10上，转动转柄14能够带动螺杆10沿轴线方向移动，螺杆10的长度方向与滑动组件3的平行移动方向保持一致。把手13通过螺纹固定联接在转柄14下端。通过转动把手13，可带动转柄14转动，并通过螺纹传动带动滑块组件3在导轨组件2上平行滑动。
本发明的工作过程是：用夹持工具将转台框架稳定放置于检测平台上，比如大理石平台，然后本发明的检测装置放置于转台框架中间位置，通过调整地脚15调整检测装置的高度，也将检测装置稳定放置于同一检测平台上。如大理石平台。夹持工具可以为千斤顶，以便于调整转台框架的高度，使得转台框 架与检测装置的高度匹配。然后微调地脚15高度，保证心轴组件6轴线与转台框架的轴线致处于同一高度。通过螺钉调节支架组件7、支架组件中调整杆在法兰座的的伸出长度，以满足不同尺寸的转台框架，通过螺钉调节表架16在支架组件7中调整杆的长度，以满足不同直径的轴孔测量。使用把手13转动转柄14，通过螺纹旋转使螺杆10转动驱动滑块组件3在导轨组件2平行滑动，进而带动支架组件7和表架16上的千分表17的平行移动，保证心轴组件6轴线与转台框架轴孔轴线处于同一直线上。通过螺钉调节并锁紧滑动V型块4在滑块组件3上的位置，使心轴组件6上的两个安装盘分别与V型块5和滑动V型块4紧密结合，防止心轴组件的左右窜动。在心轴组件6上的螺钉上均匀用力，使心轴组件6匀速转动，带动千分表17在转台框架轴孔中转动，并通过微调地脚15、转动转柄14，微调千分表17在表架16上的位置，使得心轴组件6转动时，千分表17具有读数，两块千分表17的读数差值即为转台框架两轴孔的同轴度。
此外，本发明的检测装置也可以用以检测转台框架轴孔端面的垂直度。在心轴组件6上的螺钉上均匀用力，使心轴组件6尽量匀速转动，带动心轴组件6的安装盘上一端的千分表17在轴孔端面上转动，千分表的读数视为转台框架轴孔端面的垂直度。
本发明未详细描述内容为本领域技术人员公知技术。
