Internal grinding machine for bearing ring

Abstract

The invention discloses an internal grinding machine for a bearing ring, comprising a machine body, a reciprocating work table, a workpiece axle box, a grinding wheel dresser, a grinding wheel head assembly, an operational panel, a hydraulic system, an electrical control system and a cooling system; the reciprocating work table is arranged on the machine body, the workpiece axle box is arranged at the upper part of the left end of the machine body, the grinding wheel dresser is fixed at the rear side on the machine body, the grinding wheel head assembly is arranged on the reciprocating work table, the operational panel is arranged above the right side of the machine body, the hydraulic system and the electrical control system are arranged inside the machine body, the cooling system is arranged at the rear end of the machine body. The internal grinding machine for the bearing ring has a simple structure, the rigidity of the internal grinding machine in a static state or a dynamic state is remarkably enhanced, the friction resistance is low, the wear is light, the precision retentivity is good, the vibration-damping and vibration-resisting performance is strong, the control is easy, the cutting amount adjustment is convenient, the size control is more intuitive, the maintenance is easier owning to standardization of spare parts, and the service life of the machine is longer.

Description

technical field [0001] The invention relates to bearing product processing equipment, in particular to an internal grinding machine for bearing rings. Background technique [0002] At present, the equipment used for grinding the inner diameter and inner diameter raceway of bearing products are ordinary internal cylindrical grinders, most of which are the transformation of foreign products in the 1950s and 1960s and the bearing raceways developed in China in the 1970s and 1980s. Special grinding machines, the prominent disadvantages of these equipment are low positioning accuracy, poor running rigidity, vibration, resulting in low dimensional accuracy, geometric accuracy, and surface accuracy of processed products, low efficiency, many faults, poor machine tool accuracy retention, and the processed workpieces are affected by the spindle accuracy and Positioning errors cause poor dimensional accuracy, and large shape errors cannot meet the needs of bearing product quality upgr...
