[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.
