一种WINCC刀具补偿控制系统A WINCC Tool Compensation Control System

技术领域technical field

本实用新型涉及铝合金轮毂机加工刀具损耗的安全护栏外在线补偿系统，特别是设计一种不需要进入机床加工内部就能实现的不停机刀具补偿赋值系统。The utility model relates to an external on-line compensation system of a safety guardrail for machining tool wear of an aluminum alloy wheel hub, in particular to a design of a non-stop tool compensation and assignment system that can be realized without entering the machining interior of a machine tool.

背景技术Background technique

随着企业制造自动化程度的不断提高，当前轮毂生产过程中的搬运工作已经逐渐由机器人代替人工搬运。目前轮毂加工普遍采用机床加工的方式，同时企业对生产过程效率和产品质量的要求越来越高，这就要求轮毂搬运机械手拥有更高的精度、效率和可靠性。之前同一款轮型加工分为两种方式去区分加工：1、人工测量每个轮毂毛胚尺寸，然后手动补偿测量数据差，写进加工机床系统；2、人工通过区分轮毂模号去对照之前得出的标准数值表(对应的补偿数据需要人工记忆或是手写记录下来)，进行一一对应补偿数值，当更换当前生产模号时，需要停下整套加工线，打开安全门进去加工区域，手动写进机床。研究发现，人工在发现机床在加工过程中需要人工停机进去修改加工参数所花费的时间占一天停机时间的1/3。With the continuous improvement of the manufacturing automation of enterprises, the handling work in the current wheel production process has been gradually replaced by robots instead of manual handling. At present, the processing of wheel hubs is generally carried out by machine tools. At the same time, enterprises have higher and higher requirements for production process efficiency and product quality, which requires wheel hub handling robots to have higher precision, efficiency and reliability. Previously, the same wheel type processing was divided into two ways to distinguish the processing: 1. Manually measure the size of each wheel hub blank, and then manually compensate for the difference in measurement data and write it into the processing machine system; 2. Manually distinguish the wheel hub model number to compare before The standard value table obtained (corresponding compensation data needs to be manually memorized or recorded by hand), and the compensation values shall be corresponded one by one. When changing the current production model, it is necessary to stop the entire processing line, open the safety door to enter the processing area, and manually Write into the machine. The study found that the time spent manually finding out that the machine tool needs to be stopped manually to modify the processing parameters during the processing process accounts for 1/3 of the downtime in a day.
