[0002] In the production process of gas turbine turbine equipment, turbine blades are important parts. They are made of high-temperature alloys. Turbine blades are located near the nozzle of the gas turbine, and the stability of the gas turbine is relatively high. In the production and processing of turbine blades, it is often necessary to clamp and position the turbine blades. The existing positioning fixture of turbine blades is to clamp a single blade through the existing claw equipment, and then carry out subsequent production and processing. The existing clamping operation of a single turbine blade has low production efficiency and cannot meet the requirements of mass production.
