Abstract

The invention discloses a flatness detection device which is used for detecting flatness of an oil seal of a transmission and comprises a detection platform, a dial and a rotator. The rotator is provided with a probe. The detection device is characterized in that the dial comprises a large dial and a small dial; the detection platform and the large dial are an integrated disc; the small dial is disposed above the large dial; and the small dial and the large dial share the same center of a circle. The flatness detection device has a simple structure and high detection precision, and can be used to rapidly and accurately detect flatness of an oil seal of a transmission. A flatness detection method is simple to operate, has small error and can be adopted to effectively solve the oil leakage problem of the oil seal of the transmission.

Description

technical field [0001] The invention relates to a flatness detection device and a detection method, in particular to a transmission oil seal flatness detection device and a detection method. Background technique [0002] Automobile transmission is a transmission device used to coordinate the speed of the engine and the actual driving speed of the wheels. It is an important component that affects the safety of the car. The oil leakage of the transmission oil seal has always been a research topic in the industry. [0003] The main cause of transmission oil seal oil leakage failure is the abnormal wear of the oil seal. Forced press-fitting of the oil seal during assembly, improper press-fitting, and unclean assembly environment will lead to unqualified flatness of the oil seal, resulting in abnormalities in the use of the oil seal. Wear and tear will affect the use effect of the transmission and even affect the safety performance of the car. [0004] Therefore, it is a problem...
