A high-precision polishing machine tool

Abstract

The invention discloses a high-precision polishing machine tool. The polishing machine tool comprises a machine shell, a reference part, a clamping device, a drive device, a polishing device, a cooling device and a sealing door. According to the high-precision polishing machine tool, a bearing is clamped through the clamping device, sealing is conducted through the sealing door, cooling is conducted through the cooling device, and therefore the bearing can enter a constant-temperature closed environment, the bearing in the polishing process can be cooled in time and cannot deform in the polishing process, and the polishing precision is improved. Polishing wheels which are distributed in an array manner are synchronously driven by the same drive device and make contact with the bearing at the same time, and therefore the bearing can evenly bear force in the polishing process, and the polishing efficiency is improved while precision is ensured. The reference part is in meshed transmission with a first gear through transmission teeth. Meshing is conducted on the transmission teeth through a second gear, stability of the reference part in the rotation process is improved, and the improvement of the polishing precision is facilitated.

Description

technical field [0001] The invention relates to a machine tool, in particular to a high-precision polishing machine tool. Background technique [0002] Bearings are widely used in mechanical equipment, and the structure of the bearing directly affects the maintenance cycle, service life, noise level and product qualification rate of the equipment. The bearing is composed of bearing inner ring, bearing outer ring, balls, cage, sealing ring, and grease. The surface roughness of the bearing outer ring directly affects the difficulty of assembly, the service life of the bearing, and the size of the noise during use. , the polishing in the prior art uses a single polishing wheel to polish the bearing, the efficiency is low, in the process of polishing, the force on the bearing is uneven, the heat generated during polishing is very easy to deform, and the bearing is in deformation during the polishing process After the polishing is completed and the bearing is cooled, the shape o...

The bearing is composed of bearing inner ring, bearing outer ring, balls, cage, sealing ring, and grease. The surface roughness of the bearing outer ring directly affects the difficulty of assembly, the service life of the bearing, and the size of the noise during use. , the polishing in the prior art uses a single polishing wheel to polish the bearing, the efficiency is low, in the process of polishing, the force on the bearing is uneven, the heat generated during polishing is very easy to deform, and the bearing is in deformation during the polishing process state, after the polishing is completed and the bearing is cooled, the shape of the bearing changes, and the surface roughness also changes accordingly. For bearings with high precision requirements, the expected effect cannot be achieved.
