Detailed Description
The invention will be further described with reference to the drawings and examples.
It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present application. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

when bearing rings are stacked by means of the prior art such as manual placement or traditional automatic stacking equipment, the problems of wrong stacking bearing end surfaces, uneven stacking, unstable bearing rings after being placed, falling of the rings in the process of being conveyed into a heat treatment furnace and the like exist, the conditions can influence the performance of subsequent heat treatment, and complicated picking, bending and stacking operations have very large labor intensity requirements on workers.
In view of the above problems, as shown in fig. 1 and 2, this embodiment provides a device for stacking bearing rings before heat treatment, which can identify the initial state of bearing ring placement, automatically turn over the bearing rings entering in random forward and reverse directions, make the thick end face of the bearing rings downward, then automatically and uniformly stack the bearing rings in a material frame, and automatically convey the stacked material frames to a subsequent heat treatment furnace device by a system. The device comprises a conveying mechanism 1, wherein a limiting mechanism 2 is arranged on the conveying mechanism 1, and the limiting mechanism 2 comprises a first limiting mechanism 201 and a second limiting mechanism 202;
the conveying mechanism 1 is provided with an identification mechanism 3 at the first limiting mechanism 201, and a turnover mechanism 4 is arranged at a position between the first limiting mechanism 201 and the second limiting mechanism 202; when the bearing ring 10 on the conveying mechanism 1 reaches the first limiting mechanism 201, the identifying mechanism 3 judges whether the bearing ring 10 needs to be turned over or not, and when the bearing ring 10 needs to be turned over, the turning mechanism 4 turns over the bearing ring 10 passing through the first limiting mechanism 201; the automatic overturning of the bearing rings during stacking before heat treatment is realized after identification, the problem of error of the stacking bearing end faces is solved, and the uniformity and the stability of the bearing rings are realized by the first limiting mechanism 201 and the second limiting mechanism 202.

It can be appreciated that the bearing ring 10 passes through the first limiting mechanism 201 under the transmission of the conveyor belt 101, so that the bearing ring 10 reaches the turnover mechanism 4 at the middle position of the conveyor belt 101, thus facilitating the execution of turnover action and ensuring the correctness of the end surface of the bearing; the second limiting mechanism 202 is used for arranging a plurality of bearing rings 10 side by side, so that the stacking uniformity is improved.
