Description
Technical Field
The invention relates to the technical field of grinding and polishing of annular parts, in particular to an inner and outer grinding and polishing device for a magnetic suspension bearing ring.
Background
The magnetic suspension bearing uses magnetic force to suspend the rotor in the air, so that the rotor and the stator have no mechanical contact. The principle is that the magnetic induction lines are perpendicular to the magnetic levitation lines, the shaft cores are parallel to the magnetic levitation lines, so that the weight of the rotor is fixed on a running track, the shaft cores which are almost unloaded are propped against the direction of the magnetic levitation lines, and the whole rotor is formed to be suspended and fixed on the fixed running track.
Magnetic levitation is in fact only an auxiliary function and not a separate bearing form, and the specific application also has to be matched with other bearing forms, such as magnetic levitation+ball bearings, magnetic levitation+oil bearing, magnetic levitation+vaporization bearing, etc. Compared with a common bearing, the magnetic suspension bearing also comprises an outer ring, an inner ring, rolling bodies and a retainer in composition, wherein the outer ring and the inner ring are respectively a bearing ring with a raceway on the outer surface and a bearing ring with a raceway on the inner surface; when the bearing ring is used as an outer ring, the bearing ring is usually matched with a bearing seat hole or a shell of a mechanical component to play a supporting role.
The bearing ring is required to undergo forging, heat treatment, grinding and other multi-step processes in the production and processing process, wherein the main purpose of grinding is to eliminate bulges or cracks caused by forging, heat treatment and other rough machining, reduce smoothness errors, and improve the strength and quality of contact surfaces of assembly parts so as to meet the requirement of high-precision assembly.
The grinding process requires special grinding equipment, and for the bearing ring, the high-precision component is usually required to be subjected to double grinding on the inner and outer circumferential surfaces, the conventional grinding and polishing equipment is difficult to meet the complex and high-precision polishing and polishing requirements due to the specificity of the forming surface, and the following several disadvantages exist:
1. in the existing processing technology, the polishing of the outer peripheral surface and the polishing of the inner peripheral surface of the bearing ring are respectively carried out as two completely independent processes, and the polishing of the inner peripheral surface and the outer peripheral surface of the bearing ring are difficult to synchronously carry out on the same equipment by the respective processing technology, and the processing period needs to be subjected to multiple disassembly and installation and adjustment of a clamping reference, so that on one hand, the operation is complicated, the time cost is increased, and the processing efficiency is reduced; on the other hand, the uniformity of the machining standard cannot be guaranteed through repeated disassembly and assembly, and machining errors are easily caused.
2. The clamping position and the clamping mode are not convenient to select. Firstly, in the selection of the clamping part, the bearing ring is similar to the shape of a circular ring, and the inner peripheral surface and the outer peripheral surface of the bearing ring are both processing surfaces, so that the clamping part cannot be selected for avoiding processing interference, and the opposite end surface of the bearing ring is limited by the processing mode when the opposite end surface of the bearing ring is selected as the clamping part; secondly, in the selection of the clamping mode, in the whole processing process of the bearing ring, a single clamping mode which is not invariable is adopted, and is often mutually inserted and matched with static clamping and dynamic clamping, and clamping adjustment is carried out according to actual processing requirements, but the traditional clamping mode cannot achieve the clamping effect.
3. The angle adjustment of the machining feed of the sanding polishing tool is inconvenient. In the polishing process of the bearing ring, the polishing feed and the cutting angle of the cutter are often required to be adjusted according to actual processing requirements, and some adjustment is even required to be performed in real time in the processing process, so that the traditional polishing equipment cannot meet the processing requirements.
In summary, it is clear that the prior art has inconvenience and defects in practical use, so that improvement is needed.
