Description

Technical Field

[0001] The utility model relates to the technical field of turbine blade processing, in particular to a turbine blade processing auxiliary fixture. Background Art

[0002] Turbine blades are an important component of the turbine section of a turbine engine. They include blade roots and blades connected to the blade roots. Since each turbine blade cannot be exactly the same, there will be some differences in weight and size. Therefore, the turbine blades must be clamped first during processing to facilitate measurement and subsequent processing.

[0003] In the turbine blade fixture disclosed in the Chinese utility model patent application disclosure CN211684168U, the positioning reference part and each support part are fixed on the base plate, and the limiting device is installed on the base plate through the first slide rail. When the limiting device moves along the first slide rail in the direction close to the positioning reference part to a preset locking position, the blade root included in the turbine blade is clamped between the base plate, the positioning reference part and the limiting device, so as to fix the position of the blade root. At the same time, each support part can support the blade body included in the turbine blade. It can be seen that the turbine blade can be mechanically fixed by using the fixture, thereby facilitating the marking of the QR code on the predetermined surface of the turbine blade by the marking machine needle, and then the QR code on each blade can be identified by using a barcode scanner, which helps to improve the accuracy of turbine blade position identification. However, the existing auxiliary fixture structure is relatively simple, and can only limit the turbine blade, but cannot quickly measure the size of the turbine blade, and the manual measurement accuracy is low.
