A detection device and detection method for detecting fan blades by using standard blades

Abstract

The invention discloses a detection device and a detection method for detecting fan blades by using standard blades. It comprises a bottom mold and a lifting mold. Housing, the middle housing is provided with a second positioning groove for positioning the fan blades, the first positioning groove and the second positioning groove are the same and aligned, the bottom of the second positioning groove is provided with a number of second through holes, and the top plate cover is set on the The top of the first positioning groove is provided with a number of first through holes aligned with the second through holes one by one. The first through hole is pierced with a first push rod that can be lifted, and the second through hole is pierced with an upper end with a limit position. The liftable second ejector rod at the top, several second ejector rods are of equal length, each second ejector rod upper end is provided with a tact switch, and several tact switches are connected to the indicator light and the power supply to form a series circuit. The device and method can quickly and accurately detect whether the fan blades meet the requirements, and are applicable to the detection of various fan blades with different specifications.

Description

technical field [0001] The invention belongs to the technical field of fan processing and testing equipment, and in particular relates to a detection device and a detection method for detecting fan blades by using standard blades. 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] The blades of the fan have different welding angles according to the power of the motor, and the blades of the existing fans do not have good detection tools after processing, especially the radian of the blades, which is difficult to measure. The quality of the blades must be checked. And installation consistency is very difficult to detect. Existing fan manufacturers generally only use visual inspection to inspect t...

Problems solved by technology

[0003] The blades of the fan have different welding angles according to the power of the motor, and the blades of the existing fans do not have good detection tools after processing, especially the radian of the blades, which is difficult to measure. The quality of the blades must be checked. and installation consistency is very difficult to detect

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.
