The invention provides a grinding loading disc and a grinding device which are applicable to a bearing ring. The grinding loading disc comprises a rotating outer tooth ring, a grinding mother-disk anda grinding sub-disk which are mutually nested, wherein outer teeth are arranged on the periphery of the rotating outer tooth ring; disk holes which can be matched with the appearance of the grindingsub-disk are formed in the grinding mother-disk; and positioning holes are formed in the grinding sub-disk. The grinding loading disc and the grinding device which are applicable to the bearing ring can be applicable to the grinding and machining of double end surfaces of many varieties of bearings with different specifications, is convenient for machining, reduces the machining cost and improvesthe convenience, interchangeability and universality of operation; the application range of the grinding loading disc and the grinding device is extended; meanwhile, the material performances are improved, the machining method is simple, and the machining efficiency is high, and the machining difficulty is reduced; the machining efficiency is substantially improved; and the production cycle is shortened.

Description

technical field [0001] The invention belongs to the technical field of bearing processing, and in particular relates to a carrier plate and a device for grinding double-end surfaces of bearing rings. Background technique [0002] The basic structure of the existing bearing ring double-end grinding machine grinding device is as follows: figure 1 As shown, it includes an upper grinding disc 1 and a lower grinding disc 2. The lower grinding disc 2 is evenly distributed with a grinding carrier disc 3. The grinding carrier disc 3 is the only device for processing and positioning of the grinding machine. Its structure is shown in the appendix figure 2 As shown, it is a steel integrated structure with a number of circumferentially distributed positioning holes for fixing the bearing ring. Therefore, the structure of the grinding carrier 3 is a key device that determines the processing range, processing capacity and processing accuracy of the bearing ring. There are many defects i...

AI Technical Summary

Problems solved by technology

[0003] 1. The grinding carrier is a steel integrated structure, and the structure size is single. Every time a bearing ring of a specification is processed, each grinding carrier needs to be replaced at the same time. Restricted, unable to meet the double-face grinding requirements of multi-standard and multi-variety bearing rings

Bearing processing is a multi-variety and multi-standard production method, and the two end faces of the bearing product belong to the positioning reference of the subsequent process, and the precision requirements are high. Therefore, plane grinding must be carried out. Therefore, multi-standard grinding discs are required for convenient replacement. Existing equipment cannot meet the above needs;

[0004] 2. The manufacturing cost of the grinding carrier is relatively high

Every time a bearing ring of a single specification is processed, each grinding carrier needs to be replaced at the same time to form a set of grinding device for grinding. All the grinding carriers are required to be evenly distributed on the lower grinding wheel, and all steel structures are used. The diameter of the grinding carrier is up to Φ314mm, the current market processing and manufacturing cost of the grinding carrier is quoted at about 10,000 yuan, which will occupy a large amount of cost in actual production, which is not conducive to the development of the enterprise;

[0005] 3. The manufacturing precision of the grinding carrier is high, and the processing is difficult

Among them, the machining accuracy, dimensional tolerance, verticality, and parallelism of the upper and lower end surfaces of the grinding carrier are carefully controlled. Ordinary machining equipment cannot meet the technical requirements, and the use of high-end equipment has the problem of doubling the cost;

[0006] 4. The manufacturing cycle of the grinding carrier is long

Grinding discs with steel structure need to go through many tedious processes such as rough turning, heat treatment, surface grinding, and hole grinding. Using the above equipment, it is estimated that the processing of 5 grinding discs with a single specification will take 3-4 months, which is seriously strained. long production cycle

[0007] To sum up, the configuration of the above-mentioned grinding machine cannot meet the needs of bearings with multiple varieties and specifications due to the fact that the grinding carrier plate adopts a steel integrated structure, and the size design is single, the application range is narrow, the processing is difficult, the processing accuracy is high, and the processing cycle is long. The double-end surface grinding of the ring leads to limited application range, high processing cost and long processing cycle in actual production and use. It is not suitable for the production and processing of small batches of bearing double-end surface grinding by small and medium-sized bearing manufacturers.
