Grinding wheel dressing device of bearing ring raceway grinding machine

Abstract

The invention relates to a grinding wheel dressing device of a bearing ring raceway grinding machine. The grinding wheel dressing device comprises a machine tool mounting platform, an X-direction moving platform, a Y-direction moving platform, a grinding wheel electric spindle, a grinding wheel shaft, an insulating coupling, a shaft box, an electric spark shaping device and an online electrolysisdressing device. The X-direction moving platform is arranged on one X-axis side of the machine tool mounting platform, the Y-direction moving platform is arranged on the X-direction moving platform, and the grinding wheel shaft penetrates into the shaft box and is horizontally arranged on the other X-axis side of the upper portion of the machine tool mounting platform through the shaft box. The electric spark shaping device is arranged on the Y-direction moving platform, and the online electrolysis dressing device is arranged above the shaft box. The grinding wheel dressing device has the beneficial effects that the electric spark dressing device is arranged on a machine tool while the online electrolysis dressing technology is adopted, by means of synthetic use of the two manners, the dressing effect of a grinding wheel is optimal, and the working efficiency of the grinding wheel can be greatly improved.

Description

technical field [0001] The invention relates to a grinding wheel dressing technology for a bearing raceway grinding machine, in particular to a grinding wheel dressing device for a bearing raceway grinding machine. Background technique [0002] Superabrasive grinding wheels are widely used in the finishing of bearings due to their good wear resistance. The dressing technology of superabrasive grinding wheels is a new field of dressing technology. Since the development of dressing technology, dressing tools have formed a rich series of families. Many new Advanced dressing tools are high-tech products, and the development of dressing technology tends to be high-precision, efficient and automated, which brings new topics to the dressing of superabrasive grinding wheels. [0003] At present, on more advanced machine tools, the dressing of the grinding wheel usually includes two parts, one part refers to the dressing of the grinding wheel, and the other part refers to the sharpen...

Problems solved by technology

[0003] At present, on more advanced machine tools, the dressing of the grinding wheel usually includes two parts, one part refers to the dressing of the grinding wheel, and the other part refers to the sharpening of the grinding wheel, and these two methods basically use a dressing method on a machine tool , the common trimming methods include diamond pen trimming method, diamond roller trimming method, ELID trimming method, etc.; but these single trimming methods cannot get good trimming effects, among which the diamond pen and diamond roller method have good trimming effects. However, a good sharpening effect cannot be obtained at the same time, and the grinding wheel is not sharp after shaping; the ELID repairing method is complicated in equipment and is only suitable for metal bonded grinding wheels. Easy to lose, low repair efficiency
