在机械制造中,有许多另件的加工部位相互之间既不平行又不垂直,保持着一定的角度关系。在设计这些另件的机床夹具时,如何使夹具上不平行又不垂直的表面之间,保持准确的位置和尺寸,的确是一个困难问题。近来在苏联夹具设计专家杰斯连柯的亲自指导下,采用了工艺孔的办法来解决了这一问题。所谓工艺孔,就是在夹具的适宜部位,做出一个二级精度的小孔,然后再利用这个孔间接的测出夹具各部件间的相互位置与尺寸。为了叙述方便起见,在下面
In the machinery manufacturing, there are many other parts of the processing parts are neither parallel nor vertical, maintaining a certain angle. In designing these parts of the machine tool fixture, it is indeed a difficult problem to maintain the exact position and size between the non-parallel and non-perpendicular surfaces of the fixture. Recently in the Soviet Union fixture design expert Jessica Ko personally under the guidance of the use of the method of hole approach to solve this problem. The so-called process hole, is in the appropriate parts of the fixture to make a two-precision hole, and then use this hole indirect measurement of each component of the fixture between the position and size. For the sake of narrative convenience, below
