Axial fan blade detection device

Abstract

The invention discloses an axial flow fan blade detection device, which comprises a reference platform (1), the upper surface of the reference platform (1) is a plane, and the upper surface of the reference platform (1) is provided with a blind hole (2), a A scale (4) used to measure the distance between the lowest axial point and the highest axial point of the blade of the axial flow fan and a center of the blind hole (2) for fixing the hub of the axial flow fan The annular groove (3), the blind hole (2) is provided with a bearing (5) for inserting the rotating shaft on the hub of the axial fan blade, and the scale (4) is arranged in the annular groove (3) and the reference platform ( Between the edges of 1), the axis and scale of the bearing (5) are set perpendicular to the upper surface of the reference disc (1). The present invention can detect whether the lowest point in the axial direction of each blade of the produced axial flow fan is on the same plane, and the distance between the lowest point in the axial direction and the highest point in the axial direction of each blade.

Description

technical field [0001] The invention relates to an axial flow fan blade detection device. Background technique [0002] Axial flow blades generally include a hub and several blades installed on the outer peripheral surface of the hub. One end of the hub is provided with a rotating shaft for connecting the motor rotor. When the rotating shaft is placed downward, the axial flow of each blade of the axial flow fan is required. The lowest point is on the same plane, and there are strict requirements on the distance between the axial lowest point and the axial highest point of each blade. At present, the above requirements are guaranteed through strict control of the production process, but there is no A device can be used to check whether the axial lowest point and the axial highest point of each blade of the completed axial flow fan blade are on the same plane, and the distance between the axial lowest point and the axial highest point of each blade is It is impossible to know...
