我厂生产的φ1.5×3m等型号的矿用球磨机中,均有一副轴承座和轴承支座是内、外球面相结合的重要零件。由于它们配合的球体大(SR550±0.1),球面粗糙度要求高(R_α1.6～0.2μm),内、外球表面在90°～120°区域内每25×25mm~2面积上接触不少于2点。因此,我们根据零件加工难度较大这一实际困难,专门设计制造了一套内、外合一的球面加工工具。经实际使用证明,该工具不但结构简单、性能良好、操作方便,而且成本低、效率高、应用范围广,特别适用于车削大尺寸,互相匹配的内、外球面。
I plant the φ1.5 × 3m other types of mining ball mill, there is a bearing and bearing support is inside and outside the spherical combination of important parts. Due to their large spherical size (SR550 ± 0.1), spherical surface roughness requirements (R_α1.6 ~ 0.2μm), the inner and outer ball surface in the 90 ° ~ 120 ° area 25 × 25mm ~ 2 area of contact on a lot At 2 o’clock. Therefore, we have designed and manufactured a set of spherical and spherical machining tools, both inside and outside, based on the practical difficulty of machining parts. The actual use proved that the tool not only has the advantages of simple structure, good performance and convenient operation, but also has the advantages of low cost, high efficiency and wide application range, and is particularly suitable for turning the inner and outer spherical surfaces of large size and matching each other.
