Description

油石补偿进给机构
一、技术领域：本实用新型涉及轴承滚子及圆柱形外表面的超精加工装置，尤其是油石补偿进给机构。 
二、背景技术：目前，油石进给机构对被超精工件的进给有一个汽缸来实现，由一个压力来完成，即油石的快进与超精时的压力相同；油石的装卡方式让油石有很长的距离在安装面外。由于快进时力量过大，造成油石在接触到工件时会有撞碎的情况发生。这样不但影响油石的使用寿命，油石碎片更影响超精的效果。 
三、发明内容：本实用新型的目的是提供一种工作效率较高的油石补偿进给机构，它为了克服现有的油石进给机构的缺陷，本实用新型的目的是这样实现的，本实用新型是由下托板、导轨、支架、联结块、气缸、上托板、气缸支架、销轴、气缸、导向座、挡块、压紧块、油石连接而成，下托板固定在导轨的滑块上，支架固定在下托板上，第一气缸由联结块与支架连接。 
上托板分别与联结块、导轨相连接，气缸支架固定在上托板的上端，第二气缸通过销轴与气缸支架相连接，导向座固定在上托板的下端。 
油石位于导向座的槽里面，挡块位于导向座的槽里面，挡块的前端与油石接触，压紧块由螺钉固定导向座上。 
本实用新型工作时，动作1：第一气缸的活塞杆在压缩空气的推动下，沿Z轴(向下)方向移动到限定位置，和其相连装配在一起的上托板板、气缸支架、销轴、第二气缸、导向座、挡块、压紧块、油石也随之移动到位。即让油石接触到工件。 
动作2：在油石接触到工件后，第二气缸的活塞杆在压缩空气的推动下，沿Z轴(向下)方向移动，第二气缸的活塞杆的前端压到挡块上，挡块推动油石紧压在工件上，适当调节螺钉使压紧块能使油石在合适的推力上向下移动。当油石磨损之后，第二气缸的活塞杆在压缩空气的推动下，进行补偿，直至油石消耗值设定的长度。 
动作3：当油石消耗值设定长度时，第一气缸的活塞杆在压缩空气的推动下，沿Z轴(向上)方向移动到原始位置，松开固定压紧块的螺钉，更换油石。完成一个循环。 
本实用新型的意义是：在油石进给方向上设置两层进给机构。可以方便的实现油石的快进/快退，当快进到位之后，油石已经接触到工件，然后由进给机构对工件保持一定的压力，当油石消耗后进行自动补偿。 
四、附图说明：图1为油石补偿进给机构的结构示意图，图中1、下托板    2、导轨    3、支架    4、联结块    5、气缸    6、上托板    7、气缸支架    8、销轴    9、气缸    10、导向座    11、挡块    12、压紧块    13、油石。 
五、具体实施方式：实施例1、本实用新型是由下托板1、导轨2、支架3、联结块4、气缸5、上托板6、气缸支架7、销轴8、气缸9、导向座10、挡块11、压紧块12、油石13连接而成，下托板1固定在导轨2的滑块上，支架3固定在下托板1上，第一气缸5由联结块4与支架3连接。 
实施例2、上托板6分别与联结块4、导轨2相连接，气缸支架7固定在上托板6的上端，第二气缸9通过销轴8与气缸支架7相连接，导向座10固定在上托板6的下端。 
实施例3、油石13位于导向座10的槽里面，挡块11位于导向座10的槽里面，挡块11的前端与油石13接触，压紧块12由螺钉固定导向座10上。
