DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and advantages of the utility model more clear, the technical scheme of the utility model will be described in detail below. Obviously, the described embodiments are only some embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope protected by the utility model.

[0019] Referring to Figs. 1-3As shown, the utility model provides a flexible locking tooling, including a rotating tray 1 (a carrying tray for carrying parts to be processed is fixedly connected to the outer periphery of the rotating tray), a positioning hole sleeve 2, a rotating retaining ring 3, a positioning screw 4, a disc spring 5, and a flange 6. The interior of the rotating tray 1 is a hollow structure, and a receiving cavity 11 for accommodating the disc spring 5 is provided. The disc spring 5 provides elasticity, thereby making the tooling flexible. A positioning hole 12 is provided on the top of the rotating tray 1 to connect the receiving cavity 11 with the outside world. The diameter of the positioning hole 12 is smaller than the diameter of the receiving cavity 11 to prevent the disc spring 5 from leaking out of the receiving cavity 11. The flange 6 is located at the bottom of the receiving cavity 11 and is fixedly connected to the rotating tray 1; after the flange 6 is fixed to the rotating tray 1, a cavity structure with through holes on the top and bottom is formed.
