小批量的成组螺母锁丝孔(图1)的加工,过去一直使用专用夹具或结构复杂的通用夹具。前者生产周期长,经济效益差,特别在小批量生产中更不利。后者则在每一品种零件加工时都要进行一次调整,同时也受φd、h、L尺寸的影响需换钻模板,这不便管理,易出废品。为此制作了这套磁性夹具(图2)。 Small batch group nut lock wire hole (Figure 1) of the processing, the past has been the use of special fixtures or complex structure of the common fixture. The former long production cycle, poor economic efficiency, especially in small batch production is more detrimental. The latter is in each variety of parts processing must be adjusted once, but also by the φd, h, L size need to drill template, which is not easy to manage, easy to waste. To do this made the magnetic fixture (Figure 2).
