数控激光切割机是我厂开发的一种高科技产品,滑套是该产品的一种关键零件,其加工精度直接影响激光光路的准确性,设计要求的精度很高。我们采用了较简单的工装——找正规,成功地解决了这一零件的加工难题。 1.零件的结构 零件的结构如图1,其技术要求是:34.6_(-0.04)~(-0.02)尺寸两侧面要求相互平行控制在0.02以内,且与外圆A基准面对称度控制在0.01以内;6.4_(-0.02)~0尺寸两侧面与A对称度控制在0.01以内。
CNC laser cutting machine is a kind of high-tech product developed by our factory. The sliding sleeve is a key part of this product. Its processing accuracy directly affects the accuracy of the laser light path, and the design precision is very high. We used a relatively simple tooling - to find the formal, successfully solved the machining problems of this part. 1. The structure of the parts The structure of the parts shown in Figure 1, the technical requirements are: 34.6 _ (- 0.04) ~ (-0.02) size requirements on both sides parallel to each other within 0.02 and symmetry with the cylindrical A reference plane control Within 0.01; 6.4 _ (- 0.02) ~ 0 Size Both sides and A symmetry control within 0.01.
