钢坯因生产工序的原因其表面有氧化层及缺陷，故必须通过磨削的方法进行表面修磨。针对目前没有专用的设备对大型的方形钢坯料进行表面修磨的问题，设计了一种方形钢坯修磨设备，并利用ADAMS软件完成了运动学仿真验证。结果表明，修磨设备可同时平稳完成对两相邻面的打磨作业。利用有限元软件ANSYS，对修磨机进行受载下的应力分析、模态分析，并对结构进行了改进；根据简化运动学模型进行静力学分析，得到了所需输入驱动力矩，并对关键部件弹簧完成了选型。理论计算及仿真结果表明，此修磨设备能够高效地完成对大型方形钢坯表面的磨削任务。

Billets have oxidized layers and defects on their surface due to the production process, so they must be surface?regulated by grinding. There is no special equipment for surface regrinding of large square steel billets; a square steel regrinding equipment was designed. Kinematic simulation verification was completed using ADAMS software. The results show that the regrinding equipment can simultaneously and smoothly complete the grinding operation on two adjacent surfaces. Using finite element software ANSYS to carry out stress analysis and modal analysis of the regrinding machine under load, and improve the structure; according to the simplified kinematic model, static analysis was carried out to get the required input driving torque, and the selection of the critical components of the spring was completed. Theoretical calculations and simulation results show that this regrinding machine can efficiently grind the surface of large square billets.
