液压装拆圆锥面过盈联接具有结构简单、定心性好、承载能力大、可多次拆装而不影响联接强度、不易擦伤配合面等特点,因此在齿轮箱制造生产中得到十分广泛的应用。圆锥面过盈联接配合通常采用1:50到1:30锥度面。对圆锥配合面的基本功能要求有两方面。一方面要求配合表面接触均匀,保证配合的紧密程度;另一方面要求锥面的轴向压入量在规定范围内,保证配合的过盈量。因此,在制造中必须严格检验工件内外锥体的锥度和直径。对锥体大端直径小于φ170的工件一般使用锥度环塞规(全形量规)检验。但是,大端直径更大的工件使用锥度环塞规显得笨重和不便,且量规制造成本高。为此,我们设计了一种“锥度片规”,用来检验锥体大端直径较大(φ250～φ450;1:30)的工件。
Hydraulic loading and unloading conical surface interference connection has the advantages of simple structure, good centering, large carrying capacity, can be disassembled and disassembled several times without affecting the connection strength, not easy to scratch with the surface and so on, so gearbox manufacturing in a very wide application. Conical surface interference fit with the commonly used 1:50 to 1:30 taper surface. The basic functional requirements of the cone with the two aspects. On the one hand requires the contact surface with the uniform, to ensure the tightness of the match; the other hand, the amount of axial thrust cone required within the specified range, to ensure the interference with the amount. Therefore, in manufacturing must be strictly tested inside and outside the cone taper and diameter. Cone large end diameter of less than φ170 workpiece generally use taper ring plug gauge (full scale gauge) test. However, taper ring plugs are more cumbersome and inconvenient for larger-end workpieces with larger gauge manufacturing costs. To this end, we have designed a “taper gauge” that is used to inspect workpieces with larger diameters (φ250 to φ450; 1:30) at the large end of the cone.
