Problems solved by technology

[0004] However, due to the long distance between the hub, the adjusting cylinder and the guide shaft after assembly, it is impossible to measure the coaxiality between the guide shaft and the hub with existing measuring tools, so that the distance between the guide shaft and the hub cannot be guaranteed. Assembly accuracy between

Abstract

The invention discloses a coaxiality measurement tool and a measurement method, and relates to the technical field of the measurement tool. The coaxiality measurement between a guide shaft and a wheelhub in a rotor of a wind tunnel compressor is realized, thereby guaranteeing assembling precision between the guide shaft and the wheel hub. The main technical scheme of the invention is as follows:the coaxiality measurement tool comprises a body, and a measurement barrel; the body is disciform, and a round first through hole coaxial with the body is arranged on the body, an inner diameter of the first through hole is greater than an outer diameter of the guide shaft, and a connecting part for performing coaxial connection on the body and the wheel hub is arranged on the body; and the measurement barrel is arranged on a surface of the body, the measurement barrel is coaxial with the body, and the inner diameter of the measurement barrel is greater than the outer diameter of an adjustingbarrel in a rotor. The measurement tool disclosed by the invention is mainly used for measuring the coaxiality.

Description

technical field [0001] The invention relates to the technical field of measuring tooling, in particular to a coaxiality measuring tool and a measuring method. Background technique [0002] The wind tunnel laboratory is a pipeline-shaped experimental equipment used to simulate the flow of air around an aircraft or entity, measure the effect of the airflow on the entity and observe physical phenomena. The main function of the wind tunnel compressor is to control the airflow. It is one of the main components of the wind tunnel laboratory. [0003] A wind tunnel compressor usually includes a rotor, and the rotor usually includes a hub and an adjusting cylinder arranged in the hub. The adjusting cylinder is a multi-section composite structure, and the adjusting cylinder can move along the axial direction of the rotor under the driving action of the driving mechanism, so that The blades on the hub are driven by the crank arm to rotate. The rotor is vertically assembled and used h...
