【摘要】：随着数字化工厂的诞生,企业也越来越人性化,绿色环保型的工作环境已经遍布全球,因此数控机床的噪音也越来越引起人们的关注,对机床噪音研究具有重要的实际意义。本文对重型双立柱立式车床工作台运行过程中噪音产生的原因和噪音控制措施开展研究,论文的主要研究工作有:(1)数控双立柱立式车床的结构与工作台传动原理分析首先,对数控双立柱立式车床的各主要组成部件进行介绍,了解其各主要部件的功能,熟悉其工作原理,并对工作台、齿圈、底座和主传动箱体作了详细介绍。其次,通过对数控双立柱立式车床工作台传动系统各组成部件的认识了解其传动原理,结合其传动原理图分析出工作台运行过程噪音产生的部位。(2)对多台不同型号的数控双柱立式车床在各种状态下的噪音进行检测,比较,对数据进行分析,确定产生噪音的主要因素。首先对数十台不同型号的数控双柱立式车床工作台在正常情况下运行的噪音进行检测,比较找出噪音最大的机床型号;其次将噪音最大的一类机床的不同状态进行反复测试,多组数据进行统计分析;最后根据数据寻找出工作台运行过程中产生噪音的最主要的因素。(3)根据分析出的要因制定出相应降低噪音的措施主要通过工艺手段提高关键零件的精度和装配精度,增加一些检测监控手段,确保各个环节达标且可控。(4)对降低工作台运行噪音的措施进行效果验证对噪音超标的五台产品修复的零件精度进行精度检测,合格后组装再次检测噪音确定是否超标来验证措施的可行性;并通过价值结算来判断改进措施的实用性,最后将使用改进后的加工方法对完成的产品噪音情况进行统计,进一步确定改进措施的效果。
[Abstract]:With the birth of digital factory, enterprises are becoming more and more humanized, and the environment of environmental protection has spread all over the world. Therefore, the noise of CNC machine tools has attracted more and more attention, which is of great practical significance to the research of machine tool noise. In this paper, the causes of noise and noise control measures in the running process of double column vertical lathe are studied. The main research work of this paper is as follows: (1) the structure and driving principle of CNC double vertical lathe are analyzed. This paper introduces the main components of the CNC double vertical lathe, understands the functions of the main components, and is familiar with its working principle, and introduces in detail the worktable, the gear ring, the base and the main transmission box. Secondly, through the understanding of the components of the table transmission system of the CNC double-column vertical lathe, the transmission principle is understood. Combined with its transmission schematic diagram, the position of noise generated in the running process of the worktable is analyzed. (2) the noise of several different types of NC double-column vertical lathe in various states is detected, compared, and the data are analyzed. Identify the main causes of noise. First of all, the noise of dozens of different types of NC double-column vertical lathe worktables are detected under normal conditions, and the most noisy machine models are compared to find out; secondly, the different states of the first kind of lathe with the greatest noise are repeatedly tested. Statistical analysis of multiple groups of data; Finally, according to the data to find out the most important factors that produce noise in the running process of the worktable. (3) according to the analysis of the reasons to formulate the corresponding measures to reduce the noise, mainly through the technical means to improve the accuracy of key parts and assembly accuracy, Adding some inspection and monitoring means to ensure that each link is up to standard and controllable. (4) to verify the effect of the measures to reduce the operating noise of the worktable and to check the accuracy of the parts repaired by the five products whose noise exceeds the standard. After passing the test, the assembly again detects whether the noise is over the standard to verify the feasibility of the measure; and the value settlement is used to judge the practicability of the improvement measure. Finally, the noise situation of the finished product will be counted using the improved processing method. Further determine the effect of improvement measures.
