【摘要】：機(jī)床導(dǎo)軌主要分為滑動(dòng)導(dǎo)軌、滾動(dòng)導(dǎo)軌和靜壓導(dǎo)軌三種。滑動(dòng)導(dǎo)軌剛性好、抗震動(dòng)性能強(qiáng)、制造成本低等特點(diǎn),得到比較廣泛的應(yīng)用。但是經(jīng)過長(zhǎng)時(shí)間的使用后滑動(dòng)導(dǎo)軌會(huì)出現(xiàn)一定的磨損和損傷,如果不及時(shí)對(duì)損傷的導(dǎo)軌進(jìn)行修復(fù),會(huì)嚴(yán)重影響機(jī)床的精度和使用壽命。但是由于大多的滑動(dòng)導(dǎo)軌與機(jī)床床身相連,所以對(duì)滑動(dòng)導(dǎo)軌整體更換工程量大施工困難。因此對(duì)損傷的滑動(dòng)導(dǎo)軌的修復(fù)研究具有重要意義。通過對(duì)現(xiàn)有的滑動(dòng)導(dǎo)軌修復(fù)方法進(jìn)行分析和對(duì)比后,研究了將導(dǎo)軌軟帶粘貼到動(dòng)導(dǎo)軌底面來修復(fù)導(dǎo)軌表面的修復(fù)方法,即導(dǎo)軌貼膜修復(fù)技術(shù)。本文通過對(duì)滑動(dòng)導(dǎo)軌摩擦界面的分析,探討了選用聚四氟乙烯做基材制作導(dǎo)軌軟帶。通過研究聚四氟乙烯導(dǎo)軌軟帶的特性,分析了用軟帶代替金屬做滑動(dòng)表面的可行性。同時(shí)本文研究了兩物體表面的粘接原理和導(dǎo)軌軟帶適用的膠黏劑的特性。通過研究導(dǎo)軌軟帶、膠黏劑與機(jī)床導(dǎo)軌的金屬表面相互作用的物理化學(xué)原理和結(jié)合機(jī)理,論證利用導(dǎo)軌貼膜技術(shù)修復(fù)滑動(dòng)導(dǎo)軌表面的可行性。通過對(duì)貼膜導(dǎo)軌結(jié)合面動(dòng)態(tài)特性的對(duì)比和分析,論證了導(dǎo)軌貼膜修復(fù)技術(shù)可以有效改善導(dǎo)軌動(dòng)態(tài)特性。以某生產(chǎn)線需要進(jìn)行導(dǎo)軌修復(fù)的機(jī)床為例,根據(jù)實(shí)際情況設(shè)計(jì)了導(dǎo)軌修復(fù)的總體方案。根據(jù)機(jī)床導(dǎo)軌的尺寸和貼膜厚度設(shè)計(jì)出導(dǎo)軌各部分的粗加工方案。同時(shí)設(shè)計(jì)了具體的導(dǎo)軌貼膜修復(fù)的步驟和工藝,并且根據(jù)相應(yīng)的工藝設(shè)計(jì)了對(duì)應(yīng)的輔助工具以方便修復(fù)工作的進(jìn)行。最后檢測(cè)了修復(fù)后的導(dǎo)軌位置精度,并根據(jù)導(dǎo)軌精度要求對(duì)導(dǎo)軌的位置進(jìn)行精度補(bǔ)償。
[Abstract]:The machine tool guide is mainly divided into three kinds: sliding guide, rolling guide and static pressure guide. The sliding guide rail is rigid, strong anti-vibration performance, low manufacturing cost and so on. But after a long time of use, the sliding guide rail will appear certain wear and damage, if the damaged rail is not repaired in time. The accuracy and service life of the machine tool will be seriously affected. However, most of the sliding guide rails are connected to the machine bed. Therefore, it is difficult to replace the sliding guide rail with large amount of work. Therefore, it is of great significance to study the repair of the damaged slide guide rail. Through the analysis and comparison of the existing sliding guide rail repair methods. This paper studies the method of repairing the guide rail surface by attaching the soft belt of the guide rail to the bottom surface of the moving guide rail, that is, the repair technology of the guide rail surface. The friction interface of the sliding guide rail is analyzed in this paper. The characteristics of PTFE guideway soft tape were studied by using PTFE as substrate material. The feasibility of using soft tape instead of metal as sliding surface is analyzed. At the same time, the adhesion principle of two object surfaces and the characteristics of adhesive suitable for guide rail soft belt are studied. The physicochemical principle and binding mechanism of the interaction between the adhesive and the metal surface of the guide rail of the machine tool. The feasibility of repairing the sliding guideway surface by using the technology of guide-sticking film is demonstrated. The dynamic characteristics of the bonding surface of the slide-guide-rail are compared and analyzed. The dynamic characteristics of guideway can be effectively improved by the technique of guide-patch repair. Take the machine tool needed to repair guideway in a production line as an example. According to the actual situation, the overall plan of the guide rail repair is designed. According to the size and thickness of the machine tool guide rail, the rough machining scheme of each part of the guide rail is designed. At the same time, the concrete steps and technology of the guide rail film repair are designed. According to the corresponding process, the corresponding auxiliary tools are designed to facilitate the repair work. Finally, the position accuracy of the repaired guide rail is detected, and the accuracy compensation of the guide rail position is carried out according to the precision requirements of the guide rail.
