导轨式水轮发电机定子槽楔数控液压拆装紧固装置研制

Research and manufacture of CNC hydraulic disassembly and fastening device for stator slots of guide rail type hydrogenerator

针对发电机定子绕组工作环境中振动作用严重和定子槽楔紧固的平整度要求,研制一种采用伺服液压机作为动力源并且具有反馈调节功能的导轨式水轮发电机定子槽楔数控液压拆装紧固装置.给出装置的系统架构,介绍该装置控制系统与伺服系统的基本组成和工作原理,并对主体架构中的进给系统、滚珠丝杠选型、导轨设计、工作台横向进给偏差修正及装置软件构成进行详细论述.现场测试表明,使用该装置进行槽楔紧固,能有效缩短工人工作时长并保证紧固精度和质量.该装置简单实用、安全可靠.

In view of the serious vibration in the working environment of generator stator winding and the flatness requirement of stator slot wedge fastening,we developed a CNC hydraulic disassembly and fastening device for generator stator slot wedges,which adopted servo hydraulic press as power source and had the function of feedback adjustment.We offered the system architecture of the device and introduced the basic composition and working principle of the control system and servo system of the device.We also discussed the feed system,ball screw type selection,guide rail design,workbench transverse feed deviation correction and software structure of the device in detail.The field test shows that the device can effectively shorten the working hours of workers and ensure the fastening precision and quality.The device is simple,practical safe and reliable.
