摘要
电梯曳引机箱体零件的轴承孔在加工中因尺寸深度大、刀杆悬臂过长、加工振动大等问题,产生明显的表面振纹,造成加工质量不合格的现象。通过分析零件生产的工艺过程,排查了夹具、刀粒材料、刀具角度等影响因素,锁定振动源头,设计制作刀杆的支撑装置缩短刀杆悬臂尺寸,研究和优化箱体轴承孔的加工策略,有效地避免了加工中的振动情况,使产品生产的质量问题得到了很好地解决。
In the processing of the bearing hole of the elevator traction chassis parts, problems such as large dimensional depth, too long cantilever of the tool holder, large processing vibration, etc., and obvious vibration marks on the surface, resulting in unqualified processing quality. By analyzing the process of parts production, the influencing factors such as fixture, tool grain material and tool angle are checked, the vibration source was locked, the support device of the tool holder was designed to shorten the cantilever size of the tool holder, and the processing strategy of the bearing hole of the box was studied and optimized. The vibration in the process is effectively avoided, and the quality problem of the product production is well solved.
