Wherein the second rotation shaft 22 constitutes a rotation body and the inner ring to be detected constitutes a collar to be detected. In other embodiments, the inner ring mounting seat can be directly rotatably assembled on the hinge seat through the second rotating shaft.
When the detection device is used, if the ferrule to be detected is the outer ring to be detected, the outer ring mounting seat 27 is mounted on the hinge seat 14, then the hinge seat 14 is rotated in any direction, so that a certain surface of the outer ring to be detected is clearly arranged in a microscope lens, then the hinge seat 14 is locked on the ball head 16 through the set screw 13, and finally the outer ring mounting seat 27 is rotated for a circle to observe a circle of the outer ring to be detected. In the rotating process of the outer ring mounting seat 27, the groove body 19 of the outer ring mounting seat 27 rubs against the hinge seat 14, and the outer ring to be detected is not affected.
If the ferrule to be detected is the inner ring to be detected, the inner ring mounting seat 28 is mounted on the hinge seat 14, then the hinge seat 14 is rotated in any direction, so that a certain surface of the inner ring to be detected is clearly placed in a microscope lens, the hinge seat 14 is locked on the ball head 16 through the set screw 13, and finally the inner ring mounting seat 28 is rotated for one circle to observe one circle of the inner ring to be detected. During the rotation of the inner ring mounting seat 28, the partition plate 23 of the inner ring mounting seat 28 rubs against the hinge seat 14 without affecting the inner ring to be detected.
Generally, the hinge base 14 moves counterclockwise in the state shown in fig. 1, even though the outer ring mounting base 27 and the inner ring mounting base 28 are always supported on the hinge base 14 by their own weight, so that the outer ring mounting base 27 and the inner ring mounting base 28 cannot be separated from the hinge base 14, and at the same time, are supported on the mounting base by their own weight after the bearing or the ferrule to be detected is mounted on the corresponding mounting base.
The appearance detection of the outer ring to be detected mainly comprises an inner chamfer, an outer chamfer, an inner channel, an end face and the like of the outer ring; the appearance detection of the inner ring to be detected mainly comprises an inner chamfer, an outer channel, an end face and the like of the inner ring.
It should be noted that, since the bearing to be detected includes an inner ring and an outer ring, the outer ring mount 27 and the inner ring mount 28 in this embodiment can mount the bearing to be detected to detect the appearance of the inner ring and the outer ring of the bearing to be detected.
The bearing ring appearance detection auxiliary device in the embodiment can rotate any angle after the to-be-detected ring is installed so as to observe any surface of the to-be-detected ring under a microscope, and compared with handheld detection, the bearing ring appearance detection auxiliary device avoids shaking of the to-be-detected ring and guarantees accuracy of a detection result; in addition, it is comparatively convenient not only to wait to detect the installation of lasso on the mount pad, and the change of outer lane mount pad and inner circle mount pad is also comparatively convenient moreover, treats under the big circumstances that detects of lasso, has improved detection efficiency.
