Description

Automatic assembly equipment and method for tapered roller bearing

Technical Field

The invention relates to bearing production equipment and a method, in particular to tapered roller bearing automatic assembly equipment and a method.

Background

A bearing is a mechanical element that limits relative movement to a desired range of movement and reduces friction between moving parts, and is of various types, such as tapered roller bearings, a typical tapered roller bearing having an outer race with an inner race and a set of tapered rollers enclosed by a basket-shaped cage into an inner race assembly. The tapered roller bearing is assembled by the following steps: (1) mounting the cage to the table; (2) loading tapered rollers into a cage; (3) assembling a bearing inner ring; (4) assembling the bearing outer ring. The retainer of the tapered roller bearing is of a tapered structure and comprises a large end and a small end, the side wall of the retainer is hollowed with containing positions of a rectangular structure for containing tapered rollers, the containing positions are uniformly distributed on the side wall of the retainer along the circumferential direction, and the adjacent containing positions are connected with side plates; when the conical roller is installed, the retainer needs to be installed on the workbench, and the small end of the retainer faces downwards, so that the conical roller is conveniently put into the accommodating position from the large end of the retainer. Most of the existing tapered roller bearings rely on workers to install tapered rollers in a retainer manually or by means of semi-automatic equipment, then install an inner ring in the retainer, and finally install an outer ring. However, the manual assembly of tapered rollers is low in efficiency and long in time consumption, and cannot meet the requirements of mass processing and assembly.

In order to solve the above problems, the invention patent application with application publication number CN 111927891A discloses a method for installing a bearing retainer, which comprises a bearing conveying device, a bearing retainer upper frame conveying device, a finished product conveying device, a press machine and a bearing retainer lower frame conveying device, wherein the bearing retainer upper frame conveying device comprises a flat belt, the bearing retainer is orderly placed on the flat belt in sequence after being placed by manpower, and a motor drives the flat belt to move so as to convey the retainer to a pressure head position of the press machine, so that the upper frame function of the retainer is completed. Although the above-described bearing cage installation method solves the problem of automatically transporting the cage, the following problems still remain:

1. the bearing cage loading and conveying device can only convey the orderly-state cage, but for conveying the disordered-state cage, the direction is not uniform, so that the press head of the press is not matched.

2. Before the retainer is loaded on the conveyor belt, a special process is needed to put the chaotic retainer in order, so that the workload is increased, and the working efficiency is poor.

3. The manual operation has errors when loading the retainer, and each time feeding is difficult to ensure that the retainer has the same position and posture in the circumferential direction, so that the tapered roller cannot accurately reach the correct position when blanking.

The invention patent application with the application publication number of CN 113790217A discloses a bearing needle roller assembly device, which comprises a machine body, a feeding device, an adjusting device, a pressing device and a needle loading device, wherein when the needle loading device works, a vibration disc works, a needle roller is sequentially discharged to reach a needle feeding tube, the lower end of the needle feeding tube corresponds to a bearing ring positioned on a rotary disc, the needle roller drops down one at a time, the rotary disc drives the bearing ring to rotate by one position, and the bearing needle roller is filled up by analogy. Although the above-described bearing needle assembly apparatus can replace manual assembly, the following problems still remain:

1. only one needle can be assembled at a time, and the problem of low needle assembly efficiency still exists.

2. After one needle roller is assembled, the turntable is required to rotate for an angle, then the next needle roller is assembled, the waiting time exists for assembling the needle roller, the production efficiency is reduced, and the large-batch processing and assembling are still not facilitated.
