关于一种无轨锻造操作机升降倾斜机构的优化分析

Analysis on Optimization of Lifting and Tilting Mechanism for a Trackless Forging Manipulator

本文例举了一种锻造操作机升降倾斜机构,该机构尤其适用于无轨锻造操作机。对升降轨迹进行数学建模和运动仿真,得出升降过程中相关杆件的关系方程组。在工程设计上,给定一定杆件尺寸时,能计算出剩余杆件的长度和位置,在符合精度的条件下,保证升降过程中轨迹更接近于直线。通过多组参数分析对比,得出其精度控制规律。该分析结果对于锻造操作机的结构设计和优化具有指导意义。

A kind of forging manipulator lift and tilting mechanism has been enumerated in the paper,and it is especially suitable for a trackless forging manipulator. Relation formula of related rods in the lifting process has been obtained by making mathematical modeling and movement simulation on the lifting trajectory. When a certain dimension of rod is given in engineering design,the length and location of the residual rod can be calculated,and it can be ensured that the trajectory is close to the straight line during lifting under the condition of accuracy. The accuracy control law has been obtained by comparing multiple sets of parameters. The analysis results have guiding significance for the structure design and optimization of forging manipulator.
