本实施例提供了一种发动机打标面的二次磨削装置，能够控制机构实现精确控制，无需拆除任何发动机零部件，大大简化了操作流程，降低了操作复杂度，同时也避免了因拆卸零部件可能引起的油道、水道等连接处的泄漏，减少了质量问题的发生。

如图1和图2所示，发动机打标面的二次磨削装置包括支架1、移动组件2、磨削组件4和进给组件3，支架1用于固定安装于发动机；移动组件2固定安装于支架1；进给组件3能够沿第一方向移动地安装于移动组件2，进给组件3包括固定件31、第一螺杆32和承载件33，第一螺杆32一端穿过固定件31与承载件33连接以调节承载件33沿第二方向的进给量；磨削组件4安装于进给组件3，磨削组件4被进给组件3驱动以沿第二方向靠近或者远离打标面。

由于进给组件3能够沿第一方向移动地安装于移动组件2，这样磨削组件4可沿第一方向移动，而第一螺杆32一端穿过固定件31与承载件33连接以调节承载件33沿第二方向的进给量，这样磨削组件4可沿第二方向移动，如此可通过进给组件3和移动组件2对磨削组件4进行精确控制，无需拆除任何发动机零部件，大大简化了操作流程，降低了操作复杂度，同时也避免了因拆卸零部件可能引起的油道、水道等连接处的泄漏，减少了质量问题的发生。

在一些实施例中，如图3和图4所示，固定件31具有与第一螺杆32的螺纹配合的螺纹通孔，第一螺杆32具有内螺纹孔，承载件33设置有第二螺杆34，第二螺杆34插入内螺纹孔内与内螺纹孔螺纹配合，螺纹通孔的旋向与内螺纹孔的旋向相同，内螺纹孔与第一螺杆32的外螺纹旋向相反。举例地，第一螺杆32的内螺纹孔与第二螺杆34均是左旋螺纹，第一螺杆32的外螺纹与螺纹通孔均是右旋螺纹，当第一螺杆32向右旋拧时，第二螺杆34会向前移动，反之也会向后移动，这样来控制承载件33沿第二方向移动，以实现对承载件33的进给控制。

在其他一些实施例中，固定件31具有与第一螺杆32螺纹配合的螺纹通孔，第一螺杆32具有内螺纹孔，承载件33设置有第二螺杆34，第二螺杆34插入内螺纹孔内与内螺纹孔螺纹配合，内螺纹孔、螺纹通孔、第一螺杆32的外螺纹旋向相同，内螺纹孔的螺距与外螺纹的螺距不同。当第一螺杆32向右旋拧时，由于第二螺杆34的螺距与第一螺杆32的螺距不同，这样，第二螺杆34会向前移动，反之也会向后移动，这样来控制承载件33沿第二方向移动，以实现对承载件33的进给控制。

第一螺杆32远离第二螺杆34的一端设置有磨削深度控制罗盘35，磨削深度控制罗盘35与第一螺杆32螺纹连接。磨削深度控制罗盘35为现有技术，在此不详细赘述。

在有一些实施例中，为了保证固定件31和承载件33二者在初始位置贴合，避免二者之间的距离过大造成磨削屑较多的进入，为此，承载件33朝向第一螺杆32的一侧设置有供第一螺杆32穿入的凹槽331，第二螺杆34背离第一螺杆32的一端安装于凹槽331的槽底。凹槽331的直径大于第一螺杆32的直径，如此可便于第一螺杆32插入凹槽331内。

在有一些实施例中，承载件33设置有两个间隔设置的条形孔332，条形孔332的长度沿第二方向延伸，螺栓穿过条形孔332与移动组件2连接以限制承载件33行程。如此可避免第一螺杆32旋拧过渡造成承载件33脱离移动组件2。

在一些实施例中，移动组件2包括直线滑轨21和导向件22，导向件22与直线滑轨21滑动连接，导向件22具有容纳固定件31和承载件33的容纳槽221，固定件31固定安装于容纳槽221内，承载件33能够在容纳槽221内沿第二方向移动。容纳槽221的设置可为承载件33的移动提供导向，避免承载件33移动时发生位置偏移，导向件22与直线滑轨21滑动连接能够沿第一方向移动，进而可带动磨削组件4沿第一方向一同移动，直线滑轨21和导向件22的结构简单，可使发动机打标面的二次磨削装置整体体积减小，由于磨削组件4可在第一方向和第二方向调节位置，可避免空间限制，实现打标面的二次加工。

为了保证承载件33在移动过程中更为平稳不发生抖动，容纳槽221为燕尾槽，承载件33形状与燕尾槽的形状相同。也即承载件33的两端具有与燕尾槽的槽壁相贴合的倾斜侧壁，以提高承载件33的移动平稳性。

需要说明的是，直线滑轨21的两端固定安装于支架1。

具体而言，磨削组件4通过安装架5固定安装于承载件33上。

如图1和图2所示，支架1包括连接杆11和两个支撑杆12，连接杆11的两端分别安装有一支撑杆12，两个支撑杆12安装于连接杆11的同侧。连接杆11形状为C型，此处提供了一种连接杆11的具体形状，只要能够实现将磨削组件4固定在发动机上均在保护范围内。连接杆11上具有连接孔111，螺栓穿过连接孔111将该支架1整体安装在发动机的机体上。

此外，如图5所示，发动机打标面的二次磨削装置还包括防护罩6和透明观察板7，防护罩6安装于支撑杆12，透明观察板7安装于防护罩6。防护罩6用于避免磨削屑飞溅，透明观察板7则可帮助操作人员实时获知打磨实况。
