Embodiment

[0014] Example: see figure 1 , a method for detecting the inner hole and outer diameter of a disc clutch hub, using a disc hub detection tool for detection, the disc hub detection tool includes a detection cylinder 1, the detection cylinder 1 is an open upper end and a lower end respectively Cylindrical structure. A detection pin is vertically provided in the detection cylinder 1 , and the detection pin includes aperture detection through gauges 21 and aperture detection stop gauges 22 distributed up and down, the axis of which coincides with the axis of the detection cylinder 1 . The inner diameter of the upper part of the inner wall of the detection cylinder 1 is larger than that of the lower part, and the inner diameter gradually decreases from the upper part to the lower part of the inner wall, so that the upper part of the side wall of the detection cylinder 1 forms a through gauge for outer diameter detection, and the lower part forms a stop gauge for outer diameter dete...

Abstract

The invention discloses a detection method for an inner bore and an external diameter of a disc type clutch disc hub. The method using a disc type disc hub detection tool to carry out detection comprises: (1), a to-be-detected disc hub is placed into a detection cylinder and a bore diameter detection go gauge sleeves into a shaft hole of the to-be-detected disc hub, and whether the to-be-detected disc hub is placed into the detection cylinder is observed; (2), if so, whether the bore diameter detection go gauge can pass through the shaft hole of the to-be-detected disc hub is observed; and (3), under the circumstances that the shaft hole is qualified, the to-be-detected disc hub is pressed down and whether disc hub penetrates the bore diameter detection go gauge is observed. Therefore, the detection speed becomes fast; the detection accuracy is improved; and no leak detection occurs.

Description

technical field [0001] The invention relates to the field of auto parts manufacturing, in particular to a method for detecting the inner hole and the outer diameter of a disk hub of a disc clutch. Background technique [0002] In the production process of automobiles, auto parts such as clutch hubs, etc. need to be inspected for the size of their shaft holes and outer diameters after production. During the inspection process, they are mainly inspected by special inspection tools; the existing inspection Most of the tools can only detect the aperture or outer diameter alone, so that a variety of detection tools need to be used to cooperate with the keyway during the detection process, resulting in high detection costs and inconvenient detection. The detection speed is slow and the detection efficiency is low. At the same time, due to the need to change the detection tool back and forth during the detection process, the situation of missed detection is prone to occur. Co...
