【摘要】：利用磁力研磨法,使安装在六自由度机械手的磁力研磨装置带动弯管内部的磁粒刷沿弯管中心轴线往复运动,同时磁力研磨装置旋转,解决空间弯管内表面研磨加工的技术难题。选取了影响磁力研磨工艺抛光弯管内表面的主要工艺参数(磁极转速、加工间隙、磁性磨粒粒径、轴向进给速度)并应用正交试验设计法对钛合金弯管内表面进行了研磨试验,结合试验数据对工艺参数进行了分析和优化。通过对比钛合金弯管内表面研磨前后的表面粗糙度及形貌变化,验证了采用磁力研磨工艺对弯管内表面进行光整加工的可行性和可靠性。
[Abstract]:By using magnetic abrasive method, the magnetic abrasive device installed in the six degree of freedom manipulator drives the magnetic particle brush inside the bend pipe to move back and forth along the axis of the center of the bend pipe, while the magnetic force grinding device rotates. To solve the technical problem of grinding the inner surface of the space bend pipe. The main technological parameters (magnetic pole rotation speed, machining gap, magnetic abrasive particle size, axial feed speed) which affect the inner surface of the curved pipe polished by magnetic abrasive grinding process are selected and the internal surface of the titanium alloy bend pipe is ground by orthogonal test design. The process parameters are analyzed and optimized based on the test data. By comparing the change of surface roughness and morphology before and after grinding the inner surface of titanium alloy bend pipe, the feasibility and reliability of finishing the inner surface of curved pipe by magnetic grinding technology are verified.
