Electronic testing fixture for high-pressure turbine blade clearance

The utility model provides a high-pressure turbine blade gap electronic detection tool, which belongs to the field of turbine blade detection tools and comprises a base, a detection platform, a to-be-detected part and a measurement module fixing seat. A sliding rail and an air cylinder are installed on the base, a sliding block used for driving the detection platform to move is arranged on the sliding rail in a sliding mode, and the sliding block is connected with the output end of the air cylinder; the base is provided with four thin air cylinders used for detecting lifting of the platform. The detection platform is provided with a first positioning seat, a second positioning seat, a third positioning seat and a fourth positioning seat which are used for limiting a to-be-detected part. The device can be used in a detection laboratory and can also be placed on site for operation, so that the transfer cost is saved; the blade clearance of a six-joint blade part can be detected within one minute by using three
