Device for calibrating engine blade measuring equipment

The invention belongs to the field of aviation engine blade detection, and particularly relates to a device for calibrating engine blade measuring equipment. Great measurement errors exist no matter what measurement equipment is adopted in the field of aviation engine blade detection at present, relevant dimension parameters of blades cannot be acquired accurately. In allusion to defects of existing blade measurement technologies, the invention provides a series of devices for calibrating the engine blade measuring equipment, and an equipment measurement error of the blade measuring equipment when measuring different blades can be acquired through measuring standard profiles of the devices. The invention provides an engine blade measuring equipment calibrating standard profile, an equipment system error of aviation engine blade detection can be acquired by using the profile, and a purpose of greatly improving the accuracy and the consistency of aviation engine blade measurement is achieved.
