我厂机械车间阀类小组张祥龙、顾莜兴、陈阿大等同志,在加工机、货车各种阀类产品中,经过两年来的刻苦钻研,积累了一套先进经验。从去年春天以来,他们采取边使用、边改进、边创造的办法,陆续制造了许多先进工夹具。到目前为止,这套拥有150个附件的夹具,可以加工10类阀体,共22种工件、56道工序,逐步形成为一套“万能拼合夹具”。一、“万能拼合夹具”的结构万能拼合夹具的结构如图1所示。它是由三角铁Ⅰ、龙门支架Ⅲ和一套定位了元件组成。 Zhang Xianglong, Gu 莜 Xing, Chen A and other comrades in the valve workshop of our plant have accumulated a set of advanced experience in the various valve products of processing machines and trucks for two years. Since spring last year, they have adopted a series of advanced jigs and fixtures in succession, while improving their skills and creating new ones. So far, this fixture with 150 attachments can process 10 types of valve body, a total of 22 kinds of workpieces, 56 procedures, and gradually formed into a “universal splice fixture.” First, the “universal fixture fixture” structure Universal fixture fixture structure shown in Figure 1. It consists of triangular iron Ⅰ, gantry bracket Ⅲ and a set of components.
