Description

Technical Field

[0001] The utility model relates to the technical field of clutch housing detection, in particular to a clutch housing inspection tool. Background Technique

[0002] The clutch is a key component of the automotive power transmission system and an important part of the automotive transmission. Its outer shell is particularly important. The materials of the clutch outer shell are generally metal or plastic, which determine the static and dynamic characteristics of the clutch and its ability to resist temperature aging. Therefore, the clutch outer shell is an important part of the automotive transmission.

[0003] Since the automotive clutch housing needs to meet the technical requirements of installation, sealing, positioning, and external dimensions, the dimensions controlled in the technical requirements need to be inspected and qualified before assembly. The main inspection items of the automotive clutch body include: the size and position accuracy of the cover positioning pins, the size and position accuracy of the PCBA board positioning pins, the size and position accuracy of the cover installation thread bottom holes, the size and position accuracy of the sealing ribs, the size and position accuracy of the vehicle installation holes, the DAE gasket installation holes, the ventilation holes, and the external dimensions of the ventilation holes, etc. During the production process of the clutch housing, it is necessary to detect the thickness of the outer shell of the clutch housing. Because improper outer shell thickness is likely to lead to low clutch efficiency, increased noise, or damage, it is necessary to detect the outer shell thickness to ensure that the clutch has sufficient self - protection and anti - seismic capabilities during use. The control of dimensions will also make the performance better.

[0004] However, during the detection process of the clutch housing, it is necessary to fix the clutch outer shell. The existing detection tools can only fix the outer shell that is adapted to the detection tool during detection. If it is necessary to detect outer shells of different sizes, the detection tools need to be replaced. Moreover, when detecting the outer shell thickness, the detection personnel need to constantly change positions to detect the thickness of different positions of the outer shell, making the detection more troublesome. Therefore, a new solution is needed to solve this problem. Content of the Utility Model

[0005] Aiming at the deficiencies and defects in the prior art in the above - mentioned background technique, that is, it is impossible to fix outer shells of different sizes and the detection method is relatively troublesome.
