Grinding device for impeller balance block

The utility model discloses a polishing device for an impeller balance block, which belongs to the technical field of balance block production and comprises a workbench, a fixing plate is slidably connected to the upper end of the workbench, a third motor is fixedly connected to the rear end of the fixing plate through a mounting block, and a friction wheel is fixedly connected to the output shaft end of the third motor. The driving assembly and the clamping assembly are installed at the upper end of the workbench, the extrusion assembly is arranged at the upper end of the workbench, the problem that four sharp corner welding seams exist in the welding process due to the fact that balance blocks of traditional industrial fan impellers are all square is solved, and the service life of the impellers is prolonged. 本实用新型公开了生产平衡块技术领域的一种叶轮平衡块用打磨装置，包括工作台，工作台上端滑动连接有固定板，固定板后端通过安装块固定连接有第三电机，第三电机输出轴端固定连接有摩擦轮，工作台上端安装有驱动组件和夹持组件，工作台上端设置有挤压组件，解决了传统的工业风机叶轮的平衡块的形状都是四方型，在焊接时存在四处尖角焊缝的问题，提高了叶轮使用寿命。
