Combined machining grinder for robot RV speed reducer pin wheel housing

Abstract

The invention relates to a combined machining grinder for a robot RV speed reducer pin wheel housing. The combined machining grinder comprises a grinder body, an inner hole grinding wheel and a turntable are arranged on the grinder body, the inner hole grinding wheel is used for grinding an inner hole of the pin wheel housing, the turntable is used for mounting the pin wheel housing, the inner hole grinding wheel is provided with an inner hole grinding surface for grinding the inner hole of the pin wheel housing, a pin wheel grinding wheel for grinding a pin wheel hole of the pin wheel housingis arranged on the grinder body, the pin wheel grinding wheel is provided with a pin wheel grinding surface for grinding a pin wheel hole of the pin wheel housing, and end grinding surfaces for grinding two axial end surfaces of the inner hole of the pin wheel housing are arranged on two axial end surfaces of the inner hole grinding wheel. The combined machining grinder can be clamped once, so that the pin wheel hole, the inner hole and the two axial end surfaces of the inner hole of the pin wheel housing are grinded, machining accuracy is ensured, and the manufacturing efficiency of the pinwheel housing is improved.

Description

Technical field [0001] The invention relates to a compound processing grinder for the needle tooth shell of a robot RV reducer. Background technique [0002] RV reducer is the core component of the robot, and its transmission performance directly affects the robot's motion accuracy. In the transmission of the RV reducer, the transmission of the cycloid pin wheel has the greatest impact on the accuracy of the movement, and the manufacturing accuracy of the needle gear shell of the cycloid pin wheel determines the stability, carrying capacity and life of the RV reducer. In the prior art, the processing of the needle gear shell is usually performed on the needle gear shell gear grinding machine and the internal cylindrical grinder respectively. The needle gear shell needs to be clamped twice, and the two clamping will cause the needle teeth The circle formed by the geometric center of the shell is geometrically eccentric with the inner hole of the pin tooth shell, which affects the...
