1.行程过程建议还是使用直线轴承。
2.导向柱固定板可以考虑使用图示定位方式。

四杆导向要求同轴度、平行度很高的，其实只需要2个导杆就可以了
丝杆升降机挺好用的

大侠最近也是社区里的常客，有不少很有见地的文章。
关于导向机构，我在很多帖子里也写了很多次了。当然我 ...
分享的相对到位，正好也在做这类导向机构，避免走弯路了
学习了
这个结构就算四根镀铬轴绝对平行，你怎么保证气缸顶的力使四根镀铬轴受力均匀，只要稍微有点晃动刘卡死了
我这个四导杆也实现不了吗？行程只有30mm
看了第一个图，觉得最明显的错误就石墨铜套太短，容易自锁卡死。把铜套加长就好了。
直线轴承受力大容易把珠子憋出来。

这才是专业，我刚上班的第一个产品，接触的就是导向自锁，公司还经常给设计工程师考试，就是把机械原理的这个图给抓出来。现在对各种导向中的自锁都很敏感。

铜套太短，自锁了。每个上面用俩铜套
