我厂在加工85×136往复水泵的十字头座时,根据曹乃剛同志的建議并结合沈阳机械修配厂的先进经驗,試制了一种加工胎具。利用这个胎具加工十字头座,可以保証質量,提高生产效率。同时亦解决了十字头座的1M24×2絲孔与小軸孔(φ57.3)的的中心線互相垂直問題,从而提高了十字头座的使用寿命。現將这一胎具的构造和使用方法介紹如下,供参考。
When processing the cross head of 85×136 reciprocating pumps, our factory produced a kind of processing equipment according to the suggestions of Comrade Cao Naigang and the advanced experience of Shenyang Machinery Repair Factory. The use of this tool for machining the crosshead can guarantee quality and increase production efficiency. At the same time, the problem that the centerline of the 1M24×2 wire hole and the small-axis hole (φ57.3) of the crosshead seat is perpendicular to each other is solved, thereby improving the service life of the crosshead base. The structure and method of use of this piece of equipment are described below for reference.
