The invention provides a similar threshold beam mistake proofing method. The similar threshold beam mistake proofing method comprises the following steps that S1, preliminary clamping is conducted; s2, the sensor is moved to a designated position; s3, optical fiber sensor detection; s4, magnetic sensor detection; s5, distinguishing by a judgment module; and S6, assembling and disassembling. Program processing of a PLC is adopted to judge whether the threshold beam is matched with the threshold beam needing to be machined or not, if not, equipment cannot carry out the next step, on the basis that an existing tool clamp is not changed, an optical fiber sensor and a magnetic sensor do not make contact with the product, meanwhile, threshold beam distinguishing is accurately recognized, errors are clamped in the first step of machining, and the machining efficiency is improved. The problem that assembly errors are found after machining is completed is solved, manpower and financial expenditure is greatly saved, and the problem that N60/61 threshold beam assembly errors are perfectly solved.

    本发明提供了一种相似门槛梁的防错方法,包括以下步骤:S1.初步装夹;S2.传感器至指定位置;S3.光纤传感器检测;S4.磁性传感器检测;S5.判断模块辨别;S6.装配及拆卸。本发明采用PLC的程序处理来判断是否与需要加工的门槛梁匹配,如果不匹配,设备无法进行下一步,在不改变现有的工装夹具的基础上,使用光纤传感器、磁性传感器不接触产品的本身,同时准确识别门槛梁区别,将错误卡在加工的第一步,避免了等加工完成才发现组装错误的问题,大大节约了人力和财力的支出,完美解决了N60/61门槛梁组装错误的问题。
