Abstract

The invention discloses a bearing ring grinding tool and a method, and relates to the field of bearing manufacturing. The bearing ring grinding tool and the method solve the problems in the prior artthat when the inner surface of a bearing ring is ground, process parameters cannot be fixed, the tool adjustment time is long, and the part machining quality is unstable. The end face of a positioningdatum reference scale panel is provided with a scale disc, a pivot base is fixed to the positioning datum reference scale panel through a main positioning pin and an auxiliary positioning pin, and anadjustment knob comprises a first cylinder, a second cylinder and a pointer; the second cylinder is eccentrically arranged on the end face of the first cylinder, the pointer is arranged on the outercircumference of the first cylinder, the adjustment knob is installed on the positioning datum reference scale panel, a centering shaft is installed on the adjustment knob, the outer diameter of the centering shaft is the same as the size of the outer circle of a machined ring, a horizontal pivot is slidably installed in a horizontal pivot slot, and a vertical pivot is slidably installed in a vertical pivot slot. The bearing ring grinding tool and the method are used for stabilizing and improving the grinding quality of the inner surface of the ring.

Description

technical field [0001] The invention relates to the field of bearing manufacturing, in particular to a bearing ring grinding tool and method. Background technique [0002] The stability of the grinding quality of the bearing ring is the reliability guarantee of the grinding process, and the solidification of the grinding process parameters has always been a difficult problem in the processing of bearing parts. The adjustment level of the grinding tooling directly affects the grinding quality of the bearing. Usually, when grinding the outer surface or inner surface of the ferrule, its end face and outer diameter surface are used as the processing reference. For ferrules with different sizes and structures, the operator can only manually adjust the fulcrum angle and ferrule eccentricity when processing different ferrules. Generally, it is necessary to adjust the fulcrum and eccentricity several times until the grinding quality meets the process requirements. Such a processing...
