洗衣机定时器,是洗衣机的关键件之一。有关标准规定、定时器走时精度为15分±1.5分。在大批量生产条件下如何校验15分±.5分的定时精度呢?一般厂家有的采用秒表测试,有的采用定时钟测试。不管采用上述那种方法进行测试,其测试精度均存在较大的误差,效率也很低,操作不便。今年初,我设计了一台用于校验15分±1.5分的定时器定时校验机。经过生产线上几个月的实际使用,较为理想。据我们了解,目前国内尚没有采用此种方法校验的。现简要介绍如下:
Washing machine timer, washing machine is one of the key pieces. Relevant standards, the timer travel time accuracy of 15 points ± 1.5 points. In mass production conditions how to check the accuracy of 15 minutes ± .5 minutes? Some manufacturers use stopwatch test, and some use fixed-time clock test. No matter using the above method for testing, the test accuracy has large errors, the efficiency is very low, and the operation is inconvenient. Earlier this year, I designed a timer for calibrating 15 minutes ± 1.5 minutes. After several months of actual use on the production line, the ideal. According to our understanding, at present, this method has not been adopted in China. Now briefly introduce as follows:
