The invention discloses a multi-coordinate measuring bracket for blade grid surface performance measurement. The bracket comprises a pedestal; the pedestal comprises a pedestal body, a moving slidingblock is disposed in the pedestal body, and a lead screw and a positioning rod are respectively disposed at one end of the moving sliding block in a penetrating manner; the lead screw is parallel to the positioning rod and is consistent with the blade unfolding direction of a blade grid, and the output end of a lead screw driving mechanism is connected with the lead screw; a measurement sliding block comprises a sliding block base, a sliding groove is formed in the end face of the sliding block base, and a sliding block body is arranged in the sliding groove in a matched mode. A buckle is arranged on the sliding block body and is used for fixing a measuring probe. According to the invention, the measuring probe is arranged on the sliding block body, and the sliding block body is arranged on the sliding block base in a sliding manner, so that moving measurement of the blade surface normal direction of the blade grid is realized; the sliding body is connected with the movable sliding block, and the movable sliding block is arranged on the lead screw in a sliding manner, so that the movable measurement of the blade span direction of the blade grid is realized, the movable measurementin multiple coordinate directions is met, and the structure is simple.
Description
technical field [0001] The invention belongs to the technical field of cascade performance measurement, and in particular relates to a multi-coordinate measurement bracket used for cascade surface performance measurement. Background technique [0002] The measurement of the performance parameters of the plane cascade surface is of great significance to the design of the plane cascade flow field. In order to measure the characteristics of the cascade surface, the measurement bracket needs to drive the measuring instrument to move in the four-dimensional direction; It is difficult to use large-scale measurement tools such as wind tunnels, and the measurement process is time-consuming and labor-intensive. Contents of the invention [0003] Aiming at the technical problems existing in the prior art, the present invention provides a multi-coordinate measurement support for cascade surface performance measurement to solve the problem of difficult operation and time-consuming and...
