Description

Technical Field

[0001] This utility model relates to the technical field of testing equipment for flexible flywheels, and in particular to a device for detecting the tooth profile of a flexible flywheel signal tooth. Background Technology

[0002] The flexible flywheel signal teeth detect engine speed and provide a signal to the speed sensor. The speed sensor then transmits the signal to the computer, which controls fuel injection and ignition. Without this signal, the computer cannot control fuel injection and ignition, causing the engine to malfunction. The flywheel typically has a signal disc or signal teeth for the crankshaft position sensor to detect engine speed.

[0003] The efficiency of flexible flywheel signal tooth profile detection has always been a problem for manufacturing companies, as 100% detection cannot be guaranteed; tooth profile detection equipment has a long detection time and low efficiency; resulting in difficult delivery, high costs, and inability to meet customer needs. Utility Model Content

[0004] In view of the above problems, this utility model provides a flexible flywheel signal tooth profile detection device, which can not only improve production efficiency, save costs, and shorten the delivery cycle, but also improve the reliability of detection.

[0005] To achieve the above and other related objectives, the technical solution provided by this utility model is as follows:

[0006] A flexible flywheel signal tooth profile detection device includes a base and a housing. The housing is fitted around the outer periphery of the base. A support shaft is axially positioned at the center of the base. A groove is fitted around the lower part of the support shaft. The upper surfaces of both sides of the groove are concave. A support body is fitted around the upper part of the support shaft. The top of the support body has a stop that matches the shape of the flexible flywheel. The bottom of the support body has a circular roller that mates with the concave surfaces. Both ends of the groove are connected to pull rods. One pull rod passes through a limiting groove in the housing and is hinged to the power arm of a sliding handle. The fulcrum of the sliding handle is hinged to the side wall of the housing. A toothed cover plate is provided on the top of the housing. The central limiting hole of the toothed cover plate is slidably connected to the outer periphery of the support body.

[0007] Preferably, the toothed cover plate has a toothed detection groove at its outer circumference.

[0008] Preferably, the fulcrum of the sliding handle is hinged to a support block fixed to the side of the housing.

[0009] Preferably, the toothed detection groove is configured to correspond to the flexible flywheel signal tooth of the flexible flywheel.

[0010] Preferably, the cross-sectional shape of the groove is V-shaped.

[0011] Preferably, the shell is integrally cast.

[0012] This utility model has the following positive effects:

[0013] This utility model features a support shaft and a support body that are nested and slidably connected. The bottom of the support body is equipped with a circular roller, and below the circular roller is a pull rod with a groove on it. The groove is matched and connected to the circular roller. One end of the pull rod passes through the housing and is hinged to a sliding handle. One end of the sliding handle is hinged to a support block. This not only improves the detection efficiency and reduces labor intensity, but also shortens the delivery cycle, reduces costs, and improves the reliability of the detection.
