直線導(dǎo)軌又稱滑軌、線性導(dǎo)軌、線性滑軌,用來支撐和引導(dǎo)運動部件按給定的方向做往復(fù)直線運動。在相同運動組件體積下,擁有比直線軸承更高的額定負(fù)載及運動精度,同時可以承擔(dān)一定的扭矩負(fù)載。直線導(dǎo)軌可用作水平空間的重載搬運、定位運動及豎直空間的導(dǎo)向運動,實現(xiàn)了在較小空間的可靠運動,在機床、電子電器、機器人行業(yè)都有較為廣的應(yīng)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.
直線導(dǎo)軌如何選型?
How to select linear guide rail?
1. 確定直線導(dǎo)軌的寬度;導(dǎo)軌寬度是決定導(dǎo)軌負(fù)載大小的關(guān)鍵.
1. Determine the width of linear guide rail; The width of guide rail is the key to determine the load of guide rail
2. 確定直線導(dǎo)軌長度;確定導(dǎo)軌的總長,如果設(shè)計增加防護罩,需要計算兩端防護罩的壓縮長度.一般直線導(dǎo)軌的整軌是4米,個別有超過4米的,需要和商家確認(rèn).如果選型的導(dǎo)軌長度超過現(xiàn)有的長度需要對接處理. 需要對接并且用戶想事先在機器上加工安裝孔的情況下提供接口圖紙。另一點請?zhí)貏e注意,導(dǎo)軌上的安裝孔孔間距是固定的,用戶在確定軌長時要注意位置,例:15的軌,長600。如果不告訴供應(yīng)商需要的端部尺寸,一般到貨的狀態(tài)是10個安裝孔,導(dǎo)軌兩端面到各自近的安裝孔中的距離是30、30,但也有可能是其他尺寸。各對端部尺寸的出貨規(guī)定略有差異,多數(shù)是默認(rèn)兩端相等。如果用戶要求比較,在訂購時注明誤差值或提供圖紙.
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. 確定滑塊類型和數(shù)量;常用規(guī)格的滑塊有兩種,法蘭型和方型.法蘭型高度低一點,滑塊寬度較寬,安裝孔是貫穿螺紋孔.方型高度高一點,滑塊窄一些,安裝孔是螺紋盲孔.兩種滑塊都分別有短型,標(biāo)準(zhǔn)型,加長型.主要區(qū)別是滑塊金屬長度不同.同時安裝孔也會不同,一般短型都是2個安裝孔.基本原則是:少到可以承載,多到可以安裝.
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. 確定精度等;每個廠家的直線導(dǎo)軌都會標(biāo)注精度等.一般采用精度名稱的頭一個字母,普通(N),超精度(SP),精度(UP).精度是一個綜合概念,一般由滑塊基準(zhǔn)面對導(dǎo)軌基準(zhǔn)側(cè)面的行走直線誤差.組合高度誤差,導(dǎo)程側(cè)面滑塊基準(zhǔn)側(cè)面寬度誤差,成對高度誤差和成對寬度誤差構(gòu)成.對于多數(shù)產(chǎn)業(yè)機械,普通精度就可以滿足,要求精度高一點就選擇H,數(shù)控等機床就選擇P.后面兩個等是需要苛刻的安裝和條件才展現(xiàn)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. 確定其他參數(shù);直線導(dǎo)軌和滑塊的配合預(yù)壓等,配件,加工工藝等.
5. Determine other parameters; Linear guide rail and slide block matching, preloading, accessories, processing technology, etc
