我车间制造模、夹具等分零件,一般用正弦夹具加工分度精度仅可达±2′,在大搞群众性技术革新活动中,我厂协作加工了六工位钻床上一种六方体零件,由于其分度精度要求高达±30″,所以,只能用光学分度头控制精度。但这样做,很不经济,并且也影响生产效率。老师傅田定创同志,看在眼里,急在心里,他提出用钢球定位进行分度的建议,这一建议受到了车间党组织的重视和支持,通过发动群众,并三结合小组的积极努力,经过一个月时间的努力,终于试制成功了钢球定位分度夹具(附图)。从半年多来
I workshop to create molds, fixtures and other sub-parts, the general use of sinusoidal fixture processing indexing accuracy of only ± 2 ’, in the mass of technological innovation activities, I collaborated processing plant six-bit drilling machine a hexagonal parts , Because of its indexing accuracy requirements of up to ± 30 ", therefore, can only use optical indexing head control accuracy.But doing so, it is not economical, and also affect the production efficiency.Maddy Tian Dingchuang comrades, in the eyes, Urgently in the heart, he proposed the use of ball positioning for indexing proposals, this proposal by the workshop party organizations attach importance to and support through the mobilization of the masses, and three combined with the positive efforts of the team, after a month of hard work, and finally trial Successful ball positioning indexing fixture (with photos). From more than six months
