我厂工具车间经常要磨制数量较大的各种小直径(φ3~10)的光杆冲子端面。为了保证图纸提出的端面较高垂直度和光洁度要求,我们曾先后采用过单工位单卡和多工位多卡的通用夹具和专用夹具。虽然工件质量基本得到了保证,但生产效率都很低。为了满足生产的需要,我们又设计制造了图示结构的单工位群卡专用夹具,大大提高了生产效率。若与原多工位多卡专用夹具相比,可以提高生产效率9~16.5倍,加工出的工件质量要比用原夹具好的多。
Our factory tool workshop often have to grind a large number of small diameter (φ3 ~ 10) Polish pole punch face. In order to ensure the higher verticality and finish requirements of the drawings, we have successively adopted general fixtures and special fixtures for single-station single-card and multi-station multi-card. Although the basic quality of the workpiece has been guaranteed, but the production efficiency is very low. In order to meet the needs of production, we have also designed and manufactured a single station group card dedicated fixture with graphic structure, greatly improving the production efficiency. If compared with the original multi-station multi-card fixture, you can increase the production efficiency of 9 to 16.5 times, the quality of the workpiece is much better than the original fixture.
