Detection device and method for hub of electric scooter

Abstract

The invention discloses a detection device and method for a hub of an electric scooter, and relates to the technical field of hub detection, and the key points of the technical scheme are that the detection device comprises a placing table used for placing a hub; a fixing piece which is located on the placing table and used for fixing the hub of the electric scooter; and a sampling piece. The device has the effects that the hub is placed on the placing table, the position of the irradiation lamp is adjusted through the position of the limiting plate, so that the point, irradiated on the hub, of the irradiation lamp coincides with the circle center of the hub, the camera intercepts the top view of the fixed hub, the first image acquisition unit is used for acquiring three different points a, b and c on the outer side face of the hub, the circle center of a circle where the three points are located is determined according to the three points, the circle center and the circle center, irradiated on the hub through an irradiation lamp, of the hub form the circle with the radius being R, the overlap ratio of the two circles with the radius being R is compared, and if the overlap ratio is within the range S, the roundness of the outer side surface of the hub meets the requirement, otherwise, the roundness of the outer side surface does not meet the requirementd.

Description

technical field [0001] The invention relates to the technical field of wheel hub detection, and more specifically relates to a detection device and method for a wheel hub of an electric scooter. Background technique [0002] With the continuous development of society and the continuous improvement of economic level, people pay more attention to green travel. Because electric scooters use electric energy, are environmentally friendly, convenient to charge, and have some advantages such as long standby time, it has become the first choice for people to travel short distances. The electric scooter hub is a barrel-shaped, center-mounted metal part that supports the tire on the scooter tire. [0003] At present, the detection device of the electric scooter hub on the market needs to detect the arc of the outer side of the hub. The hub is easily deformed during the production process. There is no deformation in the center to ensure the safety of the scooter in terms of quality. T...

Problems solved by technology

[0003] At present, the detection device of the electric scooter hub on the market needs to detect the arc of the outer side of the hub. The hub is easily deformed during the production process. There is no deformation in the center to ensure the safety of the scooter in terms of quality. The existing electric scooter hub detection device detects the hub, generally using a fixing device to clamp the hub, and the roundness measuring instrument is placed on the side of the outer arc of the hub , rotate the wheel hub, and judge whether the roundness of the wheel hub meets the requirements by observing the changes in the readings on the roundness measuring instrument. During the maintenance process, it is generally judged by human judgment, which is not reasonable enough. make improvements
