机械加工中,经常遇到加工壁薄的零件,而其内外圆及各台阶孔的同轴度要求很高,并且对端面的垂直度要求也很高。由于零件壁薄,既不好装夹,又容易变形,这就给加工带来较大困难。洛阳油泵厂生产约6120A型泵,其中关键零件——调速套筒就是壁厚仅有2mm的零件。为了解决加工问题,我们设计了双向开槽内夹紧装置。这种装置既能产生夹紧力,又能定位。
Machining, often encountered in the processing of thin wall parts, and its inner and outer circles and the hole of the concentricity of the demanding, and the requirements of the verticality of the end is also high. As part of the wall thin, neither good folder, but also easy to deformation, which gives the processing more difficult. About 6120A pump is produced in Luoyang Pump Factory, in which the key parts - the speed governing sleeve is the part whose wall thickness is only 2mm. In order to solve the processing problem, we designed a two-way slotted clamping device. This device can generate both clamping force, but also positioning.
