具体实施方式
为使本发明的目的、技术方案和优点更加清楚明了，下面结合具体实施方式并参照附图，对本发明进一步详细说明。应该理解，这些描述只是示例性的， 而并非要限制本发明的范围。此外，在以下说明中，省略了对公知结构和技术的描述，以避免不必要地混淆本发明的概念。
如图1-4所示，本发明提出的一种便于检测轴承的微动测量台架，包括台架1，台架1外侧壁连接有升降套2，台架1外侧壁上方对应升降套2位置处设有支撑板3，支撑板3下表面中间位置处连接有转轴4，台架1外侧壁下方对应升降套2位置处设有环套5，环套5内侧壁连接有轴承8，转轴4外侧壁通过伸缩杆64连接有挤压板65，挤压板65靠近轴承8的一侧开设有凹槽610，凹槽610内侧壁远离轴承8的一侧连接有弹簧69，弹簧69一端连接有滑板68，凹槽610内侧壁一侧连接有金属块67，挤压板65外侧壁一侧连接有蜂鸣器66。
在本实施例中，为了解决工作人员在对轴承8进行检测时，采用人工转动轴承8进行轴承8转动是否卡顿的检测，判断轴承8内部是否发生损坏的情况，人工进行判断存在较大的误差，影响检测结果准确性的问题。
如图1-3所示，工作人员在对轴承8进行检测时，可将轴承8放置在环套5内部夹持并调节升降套2的位置将转轴4插入轴承8内侧，后通过调节伸缩杆64使挤压板65与轴承8内壁紧密接触，使马达61在带动轴承8内壁进行转动的时，轴承8因内部损伤发生卡顿时，轴承8内壁与滑板68发生相对滑动，使滑板68一侧的第二金属块与金属块67接触，使电路接通蜂鸣器66发出蜂鸣告知工作人员该轴承8内部发生损伤，防止因人工判断误差造成检测结果准确性降低的情况。
需要说明的是，马达61的转速在经过减速箱62内部齿轮的减缓后带动转轴4进行转动，滑板68在弹簧69的作用下与轴承8内壁紧密接触，使轴承8内壁在发生卡顿时滑板68在转动惯性的作用下滑动与金属块67接触，金属块67、第二金属块、电源和蜂鸣器66串联在同一电路上。
在本实施例中，为了解决工作人员在对轴承8进行检测时，轴承8的外部损伤采用肉眼观测和手指滑动抚摸得到方法进行判断，使工作人员在抚摸过程中易因轴承8外部破损发生划伤的情况，给工作人员工作带来不便的问题。
如图4所示，工作人员在对轴承8进行检测时，第一红外警报器72和第二红外警报器73发出的红外线可分别被轴承8内壁和外壁阻挡，在轴承8转动过程中，破损处反射的红外线回传的距离不同，使第一红外警报器72和第二红外警报器73在检测到距离发生变化时发出警示，防止人工检测造成工作人员受伤的情况。
需要说明的是，第一红外警报器72和第二红外警报器73分别安装在对应轴承8内壁和外壁的位置处，工作人员在进行轴承8一侧的外部破损检测后，可将轴承8取下翻转进行另一面破损的检测，使台架1对轴承8的检测不会发生遗漏的情况。
在本实施例中，为了使得第二金属块与金属块67接触使电路接通，进一步的是滑板68靠近金属块67的一侧连接有第二金属块。
为了使得环套5可打开进行轴承8的放置和夹持，进一步的是环套5外侧壁一侧连接有转轮63。
为了使得转轴4得到动力，进一步的是支撑板3上表面对应转轴4位置处连接有减速箱62，减速箱62上表面连接有马达61。
为了使得灯珠71发出警示告知工作人员轴承8破损，进一步的是支撑板3上表面一侧连接有灯珠71。
为了使得轴承8一侧是否发生破损得到检测，进一步的是支撑板3下表面对应轴承8位置处连接有第一红外警报器72。
为了使得轴承8另一侧是否发生破损得到检测，进一步的是挤压板65外侧壁下方连接有连接板74，连接板74上表面对应轴承8位置处连接有第二红外警报器73。
本发明的工作原理及使用流程：工作人员在对轴承8进行检测时，可将轴承8放置在环套5内部夹持并调节升降套2的位置将转轴4插入轴承8内侧，后通过调节伸缩杆64使挤压板65与轴承8内壁紧密接触，使马达61在带动轴承8内壁进行转动的时，轴承8因内部损伤发生卡顿时，轴承8内壁与滑板68发生相对滑动，使滑板68一侧的第二金属块与金属块67接触，使电路接通蜂鸣器66发出蜂鸣告知工作人员该轴承8内部发生损伤，防止因人工判断误差造成检测结果准确性降低的情况，第一红外警报器72和第二红外警报器73发出的红外线可分别被轴承8内壁和外壁阻挡，在轴承8转动过程中，破损处反射的红外线回传的距离不同，使第一红外警报器72和第二红外警报器73在检测到距离发生变化时发出警示，防止人工检测造成工作人员受伤的情况。
应当理解的是，本发明的上述具体实施方式仅仅用于示例性说明或解释本发明的原理，而不构成对本发明的限制。因此，在不偏离本发明的精神和范围的情况下所做的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。此外，本发明所附权利要求旨在涵盖落入所附权利要求范围和边界、或 者这种范围和边界的等同形式内的全部变化和修改例。
