Description

一种行程离合装置及具有行程离合装置的角磨机 技术领域
本发明涉及安全装置技术领域，更具体地说，是涉及一种行程离合装置及具有行程离合装置的角磨机。
背景技术
现有技术中，角磨机工作片或切割片，是通过上压板和下压板及输出轴螺纹来固定。更换工作片时，通过自锁销锁住输出轴不转动，再用专用扳手旋下上压板更换磨。在中国专利CN209007330U中公布了一种角磨机用角工作片更换辅助装置，其使用时，将装置吻合卡装在角工作片固定的反向螺纹片上，转动握轮，通过螺纹缘与螺纹滑板的螺纹啮合作用，使得四个螺纹滑板内缩，继而使得夹持柱对反向螺纹片进行夹持，同时通过定位销的卡装限位，进一步转动，螺纹锁死，通过握轮扭力通过螺纹滑片传递到内盘再传递到卡盘，从而使得反向螺纹片松动，实现对角工作片的拆卸。现有技术中，只有按下自锁销按钮时，才能锁住输出轴，这样一来，拆卸工作片时，必须一手按住自锁销按钮，另一只手拿专用扳手旋上压板，操作较为繁琐、效率低。同时由于工作片是通过上压板与输出轴螺纹旋紧固定，角磨机运转一段时间容易造成下压板、工作片、上压板三者抱死，很难拆卸，使用者在用力拆卸过程中可能会出现意外伤害，造成人身伤害；另外在使用快换角磨机的时候无意触碰或振动，会使夹持装置打开或松动，松开工作片，导致工作片飞出，对人身安全造成很大的影响。

在本发明所述的行程离合装置中，所述活动组件包括移动弹簧24和多个第二活动块23，所述第二活动块23、所述移动弹簧24和所述缓冲腔主体依次连接，所述移动弹簧24和所述第二活动块23均置于所述缓冲腔内，在停止状态下，所述多个第二活动块23之间相互接触截断所述缓冲路径；在工作状态下，所述第二活动块23压缩移动弹簧24，在所述缓冲腔内形成缓冲路径。
在本发明所述的行程离合装置中，所述基座21内部具有凹陷部分，在工作 状态下，所述第二活动块23在所述凹陷部分内进行相对滑动。
