【摘要】：滚齿机是在齿轮生产加工中最为常用的齿轮加工机床设备,一般普通的滚齿机床利用展成加工的方法可以完成斜齿齿轮、直齿齿轮和人字型齿轮、圆柱齿轮以及蜗轮等的齿轮加工。本文首先介绍了普通卧式滚齿机的机床结构、加工方法、普通滚齿加工的工艺原理以及数控滚齿机的加工原理。然后针对ZFWZ12数控滚齿机大修后试加工切削齿轮齿向精度超差大于0.3mm的缺陷,分析了 ZFWZ12型数控滚齿机滚齿加工时产生齿形误差和齿向误差的主要原因以及为提高加工精度采用的对应解决方法。通过齿轮测量机对滚齿机加工试件进行精度检测并对检测结果进行分析,根据分析结论重点对滚齿机各传动部位传动精度进行检测,逐项排除超差原因,并最终发现了产生加工误差的主要原因为工作台转动超差。通过对机床小立柱进行解体,调整工作台转动蜗轮蜗杆间隙,完成机床的静态机械精度调整,再次进行齿轮试加工,通过齿轮测量机对加工试件精度的检测,进行结果分析,发现加工试件齿形误差和齿向误差满足加工产品精度要求。为减少滚齿加工过程中产生的冲击,提高机床加工精度的可靠性,最后对ZFWZ12型数控滚齿机采用双电机消除工作台转动间隙的原理及修正方法进行了分析。根据双电机消除间隙的原理,提出使用SimoComU软件,通过机床自带的611U伺服电机驱动系统,对工作台转动伺服电机参数进行优化的调整方案。介绍了SimoCom U软件的安装方法,详细介绍了 SimoCom U参数设定方法及其对伺服电机参数的优化过程。双电机消隙后,对相同试件进行滚齿加工,并用齿轮测量机进行加工试件的精度检测,发现加工试件齿形误差和齿向误差能更好地满足加工产品精度要求。从而完成大修后设备的所有精度调整。
[Abstract]:Gear hobbing machine is the most commonly used gear processing machine equipment in gear production and processing. The common hobbing machine bed can complete helical gear, spur gear and herringbone gear by the method of generalizing machining. Cylindrical gear and worm gear and other gear processing. This paper first introduces the machine structure, machining method, technology principle of common gear hobbing machine and machining principle of NC gear hobbing machine. Then, aiming at the defects of ZFWZ12 CNC gear hobbing machine, the error of cutting gear tooth direction precision is larger than that of 0.3mm. The main causes of tooth shape error and tooth direction error in hobbing machining of ZFWZ12 type NC gear hobbing machine are analyzed and the corresponding solutions to improve machining accuracy are also analyzed. The gear measuring machine is used to detect the precision of the hobbing machine and the test results are analyzed. According to the analysis conclusion, the transmission accuracy of the gear hobbing machine's transmission parts is tested, and the causes of the overshoot are eliminated one by one. And finally found that the main cause of processing error is the worktable rotation error. By disintegrating the small column of the machine tool, adjusting the clearance of the worm gear and gear of the worktable, adjusting the static mechanical precision of the machine tool, and making the gear trial processing again, the accuracy of the machined specimen is tested by the gear measuring machine, and the result is analyzed. It is found that the tooth shape error and tooth direction error of the processed specimen meet the precision requirement of the processed product. In order to reduce the impact in the process of hobbing and improve the reliability of machining accuracy, the principle and correction method of ZFWZ12 type NC gear hobbing machine using double motors to eliminate the rotary clearance of the worktable are analyzed. According to the principle of eliminating the gap between two motors, this paper puts forward a scheme of adjusting the parameters of the rotary servo motor of the worktable by using SimoComU software through the 611U servo motor drive system of the machine tool. The installation method of SimoCom U software is introduced, and the setting method of SimoCom U parameters and the optimization process of servo motor parameters are introduced in detail. After removing the clearance of the two motors, the hobbing of the same specimen is processed, and the precision of the specimen is tested by the gear measuring machine. It is found that the tooth shape error and the tooth direction error of the processed specimen can better meet the precision requirements of the processed products. In order to complete the overhaul of the equipment after all the accuracy adjustment.
