Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, in particular to a positioning device for bearing ring processing. Background Art

[0002] The bearing ring is an annular part of a radial rolling bearing with one or more raceways. The bearing ring is an important component of the bearing. At present, due to the high requirements for the machining accuracy of the bearing, the inner wall of the bearing ring needs to be polished after the production is completed. During the polishing, in order to prevent the bearing ring from shifting, a positioning device is also required to position the bearing ring.

[0003] At present, the existing bearing ring positioning devices are generally fixed by clamping. When the bearing ring is initially placed, the position needs to be constantly adjusted to avoid misalignment, which is very troublesome to use. At the same time, most bearing ring positioning devices are only applicable to bearing rings within a small range, and the versatility is relatively poor, thereby increasing the processing cost.

In order to ensure the stability of the movement of the positioning frame, a slide groove (not shown in the figure) can also be provided on the bottom plate, and a slider is provided on the positioning frame, so that the positioning frame can slide stably along the slide groove.

[0029] When in use, the bearing ring 4 is mounted on the supporting sleeve 22, and the baffle 23 is pulled outward so that the baffle 23 can rest on the bearing ring 4, so that the distance between the baffle 23 and the supporting plate 21 is adapted to the width of the bearing ring 4; the adjusting motor 35 drives the adjusting screw 32 to rotate, so that the positioning frame 31 moves downward along the adjusting screw 32, and the spherical limit members 34 on both sides below the positioning frame 31 rest on the outer side of the bearing ring 4, thereby completing the positioning work of the bearing ring 4.
