我厂检验工黄华强,最近研制成功三针测量螺纹中径百分尺。解决了检验工长期以来检测螺纹中径的困难,保证了加工螺纹的质量,工效大幅度提高。原来测量螺纹是用三针放在工件上再用分厘卡测量。由于针极易落下,因而检验者必须小心操作,速度慢,无法做到只只测量,所以就会出现有些螺纹中超差的现象。我厂生产的闸阀产品上的68根阀杆螺纹件,就是因为测量螺纹中径困难而发生超差报废
Our factory inspector Huang Huaqiang, recently developed three-pin thread diameter caliper measurement. Solve the inspection workers long-term detection of thread diameter of the difficulties to ensure the quality of processing thread, a substantial increase in efficiency. The original measurement of the thread is to use three pins on the workpiece and then points PCT measurement. Due to the needle easily fall, so the examiner must be careful operation, slow, can not do only measurement, so there will be some threads in the ultra-poor phenomenon. I plant production of the valve stem valve stem 68 pieces of material, it is because of the difficulty of measuring the diameter of the thread and the ultra-poor scrapped
