Positioning mode of linear guide rail:

，我们来了解一下直线导轨的结构。如图所示，可以直观的看到构成直线导轨的部件有滑轨、滑块和油嘴，具体结构大家可以参考网上资料自行了解。一般情况下，在滑轨和滑块的侧面有一侧是精加工面，用来做定位的挡面。

First, let's understand the structure of linear guide rail. As shown in the figure, you can intuitively see that the components constituting the linear guide rail include slide rail, slider and nozzle. For the specific structure, you can refer to the online materials to understand by yourself. Generally, one side of the side of the slide rail and slide block is the finishing surface, which is used as the retaining surface for positioning.

其次，我们再来了解一下直线导轨的实际应用。在设计过程中使用直线导轨的主要作用为支撑和引导运动部件，使其按给定的方向做往复直线运动。直线导轨常应用在精度要求比较高的机械结构中，可根据具体参数和设计要求通过计算选择与之相匹配的直线导轨。

Secondly, let's learn about the practical application of linear guide rail. In the design process, the main function of using linear guide rail is to support and guide the moving parts to make them move back and forth in a straight line in a given direction. Linear guide rail is often used in mechanical structures with high precision requirements. The matching linear guide rail can be selected through calculation according to specific parameters and design requirements.

给大家列举三种不同类型的直线导轨定位方式（主要针对双导轨使用来介绍，单导轨和双导轨是一样的机构）

Here are three different types of linear guide rail positioning methods (mainly for the use of double guide rails. Single guide rail and double guide rail are the same mechanism)

1、滑块挡面限位+滑轨定位销限位，如下图所示

1. Sliding block stop + sliding rail locating pin limit, as shown in the figure below

红色圈A：所指位置两个滑块的内侧都做了限位

Red circle a: limit is made on the inner side of the two sliding blocks at the indicated position

红色圈B：所指滑轨定位基准为一侧，另外一侧辅助安装即可。

Red circle B: the positioning reference of the slide rail is one side, and the other side can be installed with assistance.

2、滑块定位销限位+滑轨挡面限位，如下图所示

2. Sliding block locating pin limit + sliding rail stop limit, as shown in the figure below

红色圈A、B：所指位置两滑块的内侧都做了限位

Red circles a and B: limit is made on the inner side of the two sliding blocks at the indicated position

红色圈C、D：所指滑轨定位基准为一侧，另外一侧辅助安装即可。

Red circles C and D: the positioning reference of the slide rail is one side, and the other side can be installed with assistance.

3、滑块和滑轨都用定位销限位，如下图所示

3. The sliding block and slide rail are limited by locating pins, as shown in the figure below

红色圈A：所指位置两个滑块的内侧都做了限位

Red circle a: limit is made on the inner side of the two sliding blocks at the indicated position

红色圈B：所指滑轨位置为定位基准，采用定位销定位

Red circle B: the position of the indicated slide rail is the positioning reference, and the positioning pin is used for positioning

以上内容仅为小编在设计过程中接触到的，只是直线导轨定位结构中的一部分。大家在设计过程中要根据客户的具体要求及公司的内部规定，做合理的结构设计。

The above content is only a part of the linear guide positioning structure that Xiaobian came into contact with in the design process. In the design process, we should make reasonable structural design according to the specific requirements of customers and the internal regulations of the company.

备注：在设计过程中，除了要考虑直线导轨的定位问题之外，还要考虑其防尘问题（如追加防护板）、注油口注油问题（如操作是否方便）以及限制机构的位移问题等，只有这样才能设计出理想的结构。

Note: in the design process, in addition to the positioning of the linear guide rail, we should also consider its dust prevention (such as adding protective plate), oil filling at the oil filling port (such as whether the operation is convenient) and the displacement of the limiting mechanism. Only in this way can we design the ideal structure.
