Five-axis fixture for machining double-end T-shaped blade root

The utility model discloses a fixture for five-axis machining of a double-end T-shaped blade root, and relates to the technical field of machining. In order to solve the problems that an existing blade clamp can only clamp one blade every time, a clamp body needs to be turned over for machining in the machining process, consequently, the machining efficiency is low, errors exist between the machined tooth profile on the other side and the machined tooth profile datum, and the technological requirement cannot be met. A first positioning block and a second positioning block are evenly arranged on the upper surface of the base and are arranged in parallel, two threaded holes are evenly formed in the side face of the first positioning block in the length direction, a locking bolt is arranged in each threaded hole, and two pressing plates are evenly arranged on the upper surface of the second positioning block in the length direction. Each pressing plate is connected with the second positioning block through a bol
