Problems solved by technology

[0003] However, the blades of the existing fans do not have good detection tools after the processing is completed, especially the radian of the blades, which is difficult to measure, and it is very difficult to detect the quality and installation consistency of the blades
Existing fan manufacturers generally only use visual inspection to inspect the fan blades, and in the process of fan blade processing and assembly, the blades will inevitably bump, resulting in a certain deformation of the final assembled fan blades. The deformation of the blades will lead to increased fan noise, reduced energy conversion rate, and poor balance.

Abstract

The invention discloses a fan blade detection device, comprising a bottom mold and a lifting mold. The bottom mold is provided with a positioning groove for positioning the fan blades, the bottom of the lifting mold is provided with a plurality of ejector rods that can be lifted and lowered, and a plurality of The upper end of the top rod is provided with an elastic piece, and each of the top rods is provided with a conductive contact piece, wherein an indicator light and a power supply are connected between the two conductive contact pieces. When the leaf is on, a plurality of the top rods rise and fall relative to each other to connect the plurality of the conductive contacts, and form a series energizing circuit with the indicator light and the power supply. The fan blade detection device can quickly and accurately detect whether the fan blades meet the requirements, effectively prevent defective fan blades from leaving the factory, and improve product quality.

Description

technical field [0001] The invention belongs to the technical field of fan processing and testing equipment, in particular to a fan blade testing device. Background technique [0002] A fan is a commonly used ventilation device. It is mainly used for air circulation and smoke exhaust. In the production process of fans, different fans have different blade parameters, which have high requirements for the radian parameters and installation angle of the blades in the fan blades. [0003] However, the blades of the existing fans do not have good inspection tools after the processing is completed, especially the radian of the blades, which is difficult to measure, and it is very difficult to inspect the quality and installation consistency of the blades. Existing fan manufacturers generally only use visual inspection to inspect the blades, but in the process of blade processing and assembly, the blades will inevitably bump, resulting in a certain deformation of the final assemble...
