AI Technical Summary

Technical Problem

Existing oil ring processing is inefficient, and multiple processing steps can easily lead to insufficient calibration accuracy, resulting in gaps or damage at the groove.

Method used

Design a high-precision milling machine for piston rings, including a blank clamping mechanism and a double-sided milling mechanism. It uses pulleys, lead screws, and motor-driven cutters to perform synchronous milling on the oil ring blanks, ensuring precise control of the inner and outer ring grooves.

Benefits of technology

This improved the milling efficiency of oil ring blanks, avoided groove gaps or damage, and enabled high-precision machining of oil rings.

Abstract

本发明涉及活塞环加工技术领域，具体为一种活塞环高精度加工铣口机，包括油环坯料，夹装油环坯料的坯料夹装机构，承载坯料夹装机构的承载驱动机构以及安装在坯料夹装机构上的双面铣口机构；所述坯料夹装机构包括顶压件和底压件，且顶压件和底压件内部均活动安装有两个滑轮。通过利用膨胀螺栓将承载驱动机构固定在工作台上，接着将油环坯料预装配在坯料夹装机构内，直至油环坯料预工作台保持平行状态，而横置后的油环坯料可通过人工或机械臂进行圆周旋转后，被同步驱动且旋转的两个刀头可以沿着油环坯料内圈和外圈实现高效的铣口加工，进一步提高油环坯料的铣口效率。
