Embodiment 1

[0038]The auxiliary device for detecting the appearance of bearing rings in this embodiment is particularly suitable for the detection of miniature bearings and miniature rings, such asfigure 1 As shown, it includes a base and a hinged base 14. The base has a supporting surface to support it on the testing platform; the hinged base 14 is hinged on the base so that the position of the hinged base 14 in the vertical plane is adjustable, and the hinged base 14 rotates Equipped with mounting base.

[0039]Specifically, the base in this embodiment includes a seat body 11 and a pillar 12. The seat body 11 is a truncated cone structure, the pillar 12 is a cylinder, the pillar 12 extends in the vertical direction, and the lower end of the pillar 12 is fixed on the upper surface of the seat body 11. The upper end of the pillar 12 is provided with a ball head 16. Wherein, the lower end of the pillar 12 is at the center of the upper surface of the seat body 11, and the center of the ball head 16 ...

Embodiment 2

[0055]The difference between this embodiment and embodiment 1 is that in embodiment 1, the hinge seat 14 is provided with a ball socket 15 and the base is provided with a ball head 16, and the hinge seat 14 is hinged on the base through the ball socket 15 and the ball head 16. In this embodiment, the hinge seat is provided with a C-shaped groove, the base is provided with a cylinder, and the hinge seat is hinged on the base through the C-shaped groove and the cylinder.

Embodiment 3

[0057]The difference between this embodiment and embodiment 1 is that in embodiment 1, the hinge seat 14 is provided with a ball socket 15 and the base is provided with a ball head 16, and the hinge seat 14 is hinged on the base through the ball socket 15 and the ball head 16. In this embodiment, the ball socket is arranged on the base, the ball head is arranged on the hinge seat, and the hinge socket is hinged on the base through the ball socket and the ball head.

Abstract

The invention relates to an auxiliary device for detecting the appearance of a bearing / ferrule. The auxiliary device for detecting the appearance of the bearing / ferrule comprises a base which is provided with a supporting surface so as to be supported on a detection table, a hinge seat hinged to the base to enable the position of the hinge seat in a vertical plane to be adjustable, and a mountingbase used for mounting a bearing or a ferrule to be detected, and the mounting base is rotationally assembled on the hinge base around the center line of the bearing or the ferrule to be detected. After a bearing or a ferrule to be detected is mounted on the mounting base, the hinge seat can rotate at any angle, so that any surface of the ferrule to be detected can be observed under a microscope;compared with handheld detection, shaking of the ferrule to be detected is avoided, and the accuracy of a detection result is guaranteed; besides, the mounting base is rotationally assembled on the hinge seat, so that after the hinge seat is adjusted to a set position, the mounting base is rotated for a circle to observe the circle of the bearing or the ferrule to be detected, and the detection efficiency is improved.

Description

Technical field[0001]The invention relates to an auxiliary device for detecting the appearance of a bearing ring.Background technique[0002]The appearance inspection of bearings is an important inspection index for bearing inspection. Whether the appearance is qualified or not directly affects the rotation accuracy and service life of the bearing. Due to the small size of the miniature bearing and its outer diameter D≤26mm, the working surface, mating surface and other surfaces of the ring must be observed under a microscope to find out whether there are cold sensory defects on the surface of the ring, such as cracks. , Inclusions, spots, napping, abrasion, black skin and rust, etc.[0003]Under normal circumstances, the surface of the ring is observed under the microscope by holding the bearing or ring. If the batch of the bearing or ring to be inspected is large, the bearing or ring will be shaken and unstable for too long, which will affect the bearing or ring. The appearance inspec...
