A method of using an automatic grinding machine for grinding small rollers with a repairing and sharpening wheel

Abstract

The invention discloses an application method of an automatic grinding machine used for grinding a small roller and provided with a patching sharpening grinding wheel. The automatic grinding machine comprises a lathe bed, a marble table board, a bottom plate, a graphite wheel sliding plate drive device, a graphite wheel drive device, a grinding wheel device, a sharpening copper ring device, a vertical sharpening sliding plate device, a vertical sharpening drive device, an electric spindle device, a guide wheel transverse feed device, a guide wheel drive device, a supporting wheel device, the small roller, a graphite wheel sharpening device and angle plates. According to the automatic grinding machine, the small roller is subjected to grinding machining, meanwhile, the grinding wheel can becorrected online, the sharpening grinding wheel can be electrolyzed online, and therefore the grinding forming precision of the small roller is improved, the grinding efficiency is greatly improved,and cost is low; and due to the fact that the grinding size consistency of the small roller is good, the quality is stable and reliable, and the advantages that adjustment, mounting, maintaining and use are convenient are achieved.

Description

technical field [0001] The invention belongs to the technical field of small roller grinding machine grinding for bearings, and in particular relates to an automatic grinding machine using method for grinding small rollers with a modified and sharpened grinding wheel. Background technique [0002] The grinding of the crown of the small roller of the bearing generally adopts the processing method of centerless penetration. The processing method of centerless penetration has the advantage of high processing efficiency. The method of forming the convexity curve is the Fancheng method. The shape and amount of convexity depend on the attitude of the roller. , through the trajectory and the contour shape of the grinding wheel face. [0003] Although the centerless grinding method has high production efficiency and is easy to realize automation and mass production, its machining accuracy depends heavily on the mechanical structure and precision of the machine tool, and there are st...

Problems solved by technology

[0003] Although the centerless grinding method has high production efficiency and is easy to realize automation and mass production, its machining accuracy depends heavily on the mechanical structure and precision of the machine tool, and there are still changes in the center position of the workpiece, errors between the linear motion of the workpiece center and the axis of the grinding wheel, and the The error of the movement speed, the instability of the contact with the working surface of the pallet, and the wear of the grinding wheel and the guide wheel itself have greatly affected the improvement of the machining accuracy and consistency.

Therefore, the existing centerless cylindrical grinding technology and machine tools have been difficult to meet the technical requirements of the market, and further in-depth research and upgrading are urgently needed in terms of processing principles, machine tool structure design and processing technology.
