The invention relates to a clamping structure of flange cutter for integral blade disc milling. The disc milling cutter is mounted on one side of the flange by a key, and the internal threads of the two compacting blocks are rotated with the external threads on the flange to make the compacting blocks compress the disc milling cutter to form a high rigid clamping structure of the disc milling cutter. When changing the cutter, the wrench is stuck in the slot corresponding to the two pressing blocks respectively, and the two pressing blocks are removed in turn to change the cutter of the disk milling cutter. The structure can effectively reduce the vibration of the disc milling cutter during the machining process, increase the rigidity of the disc milling structure, improve the machining quality of the aircraft blade disc, and realize the rapid tool change and improve the machining efficiency of the integral blade disc. The number of the parts in the invention is small, including flange, disk milling cutter, big pressing block, small pressing block and flat key. By locating the end face of the flange and locking the big and small pressing block, not only the installation and positioning accuracy of the disk milling cutter can be improved, but also the tool changing speed of the disk milling cutter can be greatly improved, and the tool changing time of the background technology can be increased by three times. Up.

技术介绍
文献1“授权公告号CN203019101U的中国技术”,公开了一种开式整体叶盘快速换刀装置。结合附图1,该装置中所有的零件都安装在箱体9内,盘铣刀2与铣刀轴22通过两个平键14连接,铣刀轴22的锥面与铣刀齿轮轴8的锥孔配合,拉钉7沿铣刀齿轮轴8内的拉钉孔穿过铣刀齿轮轴8与铣刀轴22螺纹连接,锁紧螺母21与铣刀轴22通过螺纹连接,凸块13和套环15对铣刀2进行轴向定位,第一轴套10、第二轴套11、轴瓦16、第三轴套17、第四轴套18、第五轴套19、第六轴套20起到调整轴向间隙的作用。换刀时,松开锁紧螺母21和拉钉7,将铣刀轴22沿轴线方向外抽到足够的空间可更换盘铣刀2。该装置中零件数目多,造成安装定位不精确,换刀时间长,从而不能起到快速换刀的作用。整体叶盘是高推重比、高性能发动机的核心部件,也是航空航天、国防、能源、动力等领域重大装备实现减重、增效和改善性能的关键零件。与传统叶片和轮毂装配结构相比,整体叶盘省去榫头、榫槽及相 ...
