怎样才能找到自己想要的导轨丝杠?

来源:http://www.jngongrun.com/ 日期:2022-03-26 发布人:

直线导轨又称滑轨、线性导轨、线性滑轨,用来支撑和引导运动部件按给定的方向做往复直线运动。在相同运动组件体积下,拥有比直线轴承更高的额定负载及运动精度,同时可以承担一定的扭矩负载。直线导轨可用作水平空间的重载搬运、定位运动及竖直空间的导向运动,实现了在较小空间的可靠运动,在机床、电子电器、机器人行业都有较为广的应用。

Linear guide rail, also known as slide rail, linear guide rail and linear slide rail, is used to support and guide moving parts to make reciprocating linear motion in a given direction. Under the same moving component volume, it has higher rated load and motion accuracy than linear bearing, and can bear a certain torque load at the same time. Linear guide rail can be used as heavy load handling, positioning movement in horizontal space and guiding movement in vertical space, which realizes reliable movement in small space. It is widely used in machine tool, electronic appliance and robot industry.
直线导轨如何选型?
How to select linear guide rail?
1. 确定直线导轨的宽度;导轨宽度是决定导轨负载大小的关键.
1. Determine the width of linear guide rail; The width of guide rail is the key to determine the load of guide rail
2. 确定直线导轨长度;确定导轨的总长,如果设计增加防护罩,需要计算两端防护罩的压缩长度.一般直线导轨的整轨是4米,个别有超过4米的,需要和品牌商家确认.如果选型的导轨长度超过现有的长度需要对接处理. 需要对接并且用户想事先在机器上加工安装孔的情况下提供接口图纸。另一点请特别注意,导轨上的安装孔孔间距是固定的,用户在确定轨长时要注意位置,例:15的轨,长600。如果不告诉供应商需要的端部尺寸,一般到货的状态是10个安装孔,导轨两端面到各自近的安装孔中的距离是30、30,但也有可能是其他尺寸。各品牌对端部尺寸的出货规定略有差异,多数是默认两端相等。如果用户要求比较,在订购时注明误差值或提供图纸.
2. Determine the length of linear guide rail; Determine the total length of the guide rail. If the protective cover is designed to be added, the compression length of the protective cover at both ends needs to be calculated Generally, the whole track of linear guide rail is 4 meters, and some are more than 4 meters, which needs to be confirmed with brand merchants If the length of the selected guide exceeds the length of the existing docking guide When docking is required and the user wants to process the mounting hole on the machine in advance, the interface drawing shall be provided. On the other hand, please pay special attention to that the distance between the mounting holes on the guide rail is fixed. Users should pay attention to the position when determining the rail length, for example, the rail of 15 is 600 long. If the supplier is not informed of the required end size, the general arrival status is 10 mounting holes, and the distance from the two ends of the guide rail to the respective adjacent mounting holes is 30, 30, but it may also be other sizes. The shipping regulations of each brand on the end size are slightly different, and most of them are equal at both ends by default. If the user requires comparison, indicate the error value or provide drawings when ordering
3. 确定滑块类型和数量;常用规格的滑块有两种,法兰型和方型.法兰型高度低一点,滑块宽度较宽,安装孔是贯穿螺纹孔.方型高度高一点,滑块窄一些,安装孔是螺纹盲孔.两种滑块都分别有短型,标准型,加长型.主要区别是滑块金属长度不同.同时安装孔也会不同,一般短型都是2个安装孔.推荐基本原则是:少到可以承载,多到可以安装.
3. Determine the type and quantity of sliding blocks; There are two kinds of commonly used sliding blocks, flange type and square type The width of the slide block is lower, and the height of the threaded hole is lower The height of the square is higher, the slider is narrower, and the mounting hole is a threaded blind hole The two sliders are short, standard and extended respectively The main difference is that the metal length of the slider is different At the same time, the mounting holes will be different. Generally, the short type has 2 mounting holes The basic principle of recommendation is: as little as possible to carry, as much as possible to install
4. 确定精度等;每个厂家的直线导轨都会标注精度等.一般采用精度名称的头一个字母,普通(N),超精度(SP),精度(UP).精度是一个综合概念,一般由滑块基准面对导轨基准侧面的行走直线误差.组合高度误差,导程侧面滑块基准侧面宽度误差,成对高度误差和成对宽度误差构成.对于多数产业机械,普通精度就可以满足,要求精度高一点就选择H,数控等机床就选择P.后面两个等是需要苛刻的安装和条件才展现得出它的性能.
4. Determine the accuracy, etc; The linear guide rail of each manufacturer will be marked with accuracy, etc Generally, the first letter of precision name, ordinary (n), super precision (SP) and precision (up), is used Precision is a comprehensive concept, which is generally determined by the linear error of the sliding block datum facing the side of the guide rail datum Combined height error, lead side slider reference side width error, paired height error and paired width error For most industrial machinery, ordinary precision can be met. If the precision is higher, choose h, and CNC machine tools choose P. the latter two need harsh installation and conditions to show its performance
5. 确定其他参数;直线导轨和滑块的配合预压等,配件,加工工艺等.
5. Determine other parameters; Linear guide rail and slide block matching, preloading, accessories, processing technology, etc
