Secondly, let's learn about the practical application of linear guide rail. The main function of using linear guide rail in the design process is to support and guide the moving parts to make them do reciprocating linear motion in a given direction. Linear guides are mostly used in mechanical structures with high precision requirements. According to specific parameters and design requirements, matching linear guides can be selected through calculation.
Finally, I will give you three different types of linear guide positioning methods (mainly for double guide rails, and single guide rail and double guide rail are the same mechanism).
1, the limit of the sliding block surface+the limit of the locating pin of the slide rail, as shown in the following figure:
Red circle A: In the position shown, the inner sides of the two sliders are limited.
Red circle B: The positioning reference of the slide rail refers to one side, and the other side is used for auxiliary installation.
2. Slider locating pin limit+slide rail stop surface limit, as shown in the following figure:
Red circles A and B: In the position shown, the inner sides of the two sliders are restricted.
Red circles C and D: The positioning reference of the slide rail refers to one side and the other side is used for auxiliary installation.
3. Both the slider and the slide rail are limited by the locating pin, as shown in the following figure:
Red circle A: In the position shown, the inner sides of the two sliders are limited.
Red circle B: The position of the slide rail is the positioning reference, and the positioning pin is used for positioning.
