Description

Technical Field

[0001] The utility model relates to the technical field of fan blade support frame detection, in particular to a fan blade support frame detection device. Background Art

[0002] The fan is a machine that relies on input mechanical energy to increase gas pressure and transport gas in parallel. It is a driven fluid machine. The fan blade support frame needs to be inspected during the production process to prevent the fan from malfunctioning due to unqualified support frame quality when the fan is in use.

[0003] For example, the Chinese utility model patent with application number 202322094566.2 discloses a detection device for a fan blade support frame. The patent includes a bottom plate, a detection display device is fixedly connected to the top of the front end of the fixing plate, a screw is fixedly connected to the output end of the second motor, a nut pair is passed through and threadedly connected to the middle of the outer diameter of the screw, and a first electric push rod is fixedly connected to the bottom of the nut pair. The motor drives the screw to rotate, so that the nut pair drives the probe to move forward and backward to detect different points of the support frame;

[0004] Although the above document solves the problem that the existing detection equipment of the fan blade support frame cannot move the probe left and right when in use, and the existing detection equipment of the fan blade support frame cannot flip the support frame during detection, there is still a disadvantage of low detection efficiency. The support frame is conveyed to the clamping mechanism for clamping by a conveyor belt, which not only cannot ensure the correct clamping position, but also cannot be easily removed after the detection is completed. For this reason, a detection equipment for the fan blade support frame is introduced here. Utility Model Content
